A diagram-first engineering guide that turns half-remembered aerodynamics into calculable physics, from pressure distributions and boundary layers to drag polars, critical Mach number and shock waves.

Passing the journeyman exam is not a memory test—it is a speed test in a book you are allowed to bring.

This study guide teaches you to navigate the National Electrical Code the way the exam demands: find the article, read the exception, run the numbers, move on. Instead of memorizing isolated facts, you will learn a repeatable method for locating code requirements quickly, applying exceptions correctly, and performing the calculations that appear on every journeyman examination. The focus is on the skills that actually save time in the exam room: knowing how the Code is organized, recognizing which article governs a question, and working through the math without hesitation.

You will work through conductor ampacity and correction factors, voltage drop, raceway and box fill, branch circuits and required outlets, dwelling and commercial load calculations, services, grounding and bonding, overcurrent protection, motor and air conditioning circuits, transformers, and special occupancies. More than four hundred practice questions across four timed exams show the calculation and the article behind every answer, so you can see not only what the correct answer is but where it comes from in the Code. Each chapter builds the habits that separate candidates who finish from those who run out of time.

What you will learn:

• How the National Electrical Code is organized and how to find the right article fast
• Electrical theory the exam assumes you already know
• Conductor ampacity, correction factors, and adjustment for temperature and conduit fill
• Voltage drop calculations and conductor selection
• Wiring methods, raceway fill, boxes, conduit bodies, and enclosures
• Branch circuits, required outlets, and receptacle placement
• Dwelling, commercial, and multifamily load calculations
• Services, service equipment, grounding, bonding, and overcurrent protection
• Motors, air conditioning circuits, transformers, and special occupancies

Written for apprentices sitting the journeyman exam, electricians upgrading their licence, and instructors running exam-prep classes, this guide turns the Code into a working tool. If you need to build speed, accuracy, and confidence with the National Electrical Code before exam day, this book is designed for you.

L’algèbre linéaire occupe une place centrale dans les mathématiques contemporaines. Véritable langage universel, elle offre un formalisme rigoureux et un cadre conceptuel puissant, indispensables à tout étudiant souhaitant poursuivre des études approfondies en mathématiques. Au-delà de son importance théorique, elle constitue également un outil fondamental pour la modélisation et l’analyse de nombreux phénomènes issus de disciplines variées telles que la mécanique, l’électronique, l’économie ou encore l’informatique.

Cette nouvelle édition, soigneusement corrigée et enrichie de nombreux exercices supplémentaires, est le fruit de plusieurs années d’enseignement de l’algèbre générale, linéaire et bilinéaire, dispensé successivement en MPII puis en SMA. Elle s’adresse principalement aux étudiants de licence en mathématiques, aux élèves des classes préparatoires de la filière MP, ainsi qu’à toute personne préparant les concours de l’enseignement.

L’ouvrage est structuré de manière progressive en onze chapitres avec :

• Les démonstrations des théorèmes et des propositions, présentées avec rigueur et clarté afin de permettre au lecteur d’acquérir des méthodes de raisonnement solides.
• Des exemples explicatifs.
• De nombreux exercices résolus facilitant l’assimilation des notions fondamentales. Plusieurs exercices classiques ont été intégrés au corps du cours sous forme de propositions démontrées, renforçant ainsi la cohérence et la continuité de l’exposé.

Start at a single logic gate and finish able to explain how a pipelined processor executes your C code.

This book never skips a layer. You build combinational blocks into an arithmetic logic unit, add flip-flops and timing constraints, design finite state machines, and model all of it in a hardware description language with testbenches. Then you meet the instruction set: register formats, encodings, assembly control flow, procedures and the stack, and the exact path from C source through compiler and linker to memory.

From there you construct a single-cycle datapath, pipeline it, resolve data and control hazards with forwarding and stalls, and measure the result. Caches, virtual memory, multicore parallelism and device input and output close the book. Every chapter connects the abstract model to the concrete hardware, so you always know which layer you are standing on and why the next one matters.

What you will learn:

• Convert between number systems and represent signed and unsigned values in binary
• Apply Boolean algebra to simplify expressions and build logic gates
• Combine gates into adders, multiplexers, decoders and other combinational blocks
• Use flip-flops, clocks and timing constraints to create reliable sequential logic
• Design finite state machines and implement them in a hardware description language with testbenches
• Read and write RISC-V assembly, including control flow, procedures and stack discipline
• Trace the path from C source through compiler and linker to machine code in memory
• Construct a single-cycle datapath and then pipeline it with forwarding and stalls
• Evaluate branch prediction, caches, virtual memory, parallelism and input-output

For computer engineering students and self-taught systems programmers who want a complete, hands-on path from digital logic to a working pipelined RISC-V processor. If you have basic programming experience and are ready to understand the hardware-software interface from the ground up, this book is for you.

Treatment plants run on numbers—and this book gives you all of them in order.

Water and wastewater treatment is a discipline of measured inputs and verified outputs. This practical guide walks you through the calculations, process fundamentals, and laboratory methods that decide compliance and plant performance. You will begin with source water demand and the permitting framework, then move into the chemistry and sampling protocols that underpin every operational decision—from oxygen demand and suspended solids to coliform testing and proper sample preservation.

Design chapters show you how to size flocculation basins by mixing energy, clarifiers by overflow rate, filters by loading and backwash, and disinfection systems by contact time and ultraviolet dose. Wastewater chapters cover screening and grit removal, activated sludge control by sludge age and mixed liquor solids, fixed-film and lagoon systems, nitrogen and phosphorus removal, and digestion with biogas recovery. Throughout, worked control calculations and end-of-part review questions reinforce each concept, preparing you for certification exams and real-world process decisions.

What you will learn:

• Estimate water demand and navigate the regulatory and permitting framework for treatment systems
• Apply water chemistry fundamentals and proper sampling, preservation, and laboratory examination methods
• Perform hydraulic and conveyance calculations for pipes, pumps, and open channels
• Design coagulation, flocculation, and sedimentation units using mixing energy and overflow rate
• Size filtration and membrane systems by loading rate and backwash requirements
• Calculate disinfection contact time and ultraviolet dose for pathogen inactivation
• Control activated sludge processes using sludge age, mixed liquor solids, and oxygen demand
• Evaluate fixed-film, lagoon, and nutrient removal processes for nitrogen and phosphorus
• Manage solids handling, digestion, and biogas recovery for resource recovery

Whether you are a plant operator preparing for certification, a process engineer refining treatment performance, or an environmental engineering student building a working knowledge of treatment design, this book provides the ordered calculations and clear explanations you need to operate and design with confidence.

Radar is not two subjects. It is one continuous path from field physics to detected target.

Most books treat antennas and signal processing as separate disciplines. This book connects them. You start with electromagnetic propagation and the radar range equation, then build aperture and phased-array design directly from radiation integrals. From there, you move into waveform choice, matched filtering, and the complete FMCW chirp chain—from sweep parameters to the range-Doppler map. The result is a single, coherent framework that shows how physics constrains algorithms and how algorithms exploit physics.

Later chapters extend the path to CFAR detection, monopulse and MIMO angle estimation, Kalman tracking, and SAR image formation. Every concept is reinforced with worked numbers you can check against your own designs. Whether you are optimizing an automotive radar sensor or simulating a synthetic aperture system, you will find the equations, block diagrams, and practical trade-offs needed to move from theory to implementation.

What you will learn:

• Apply electromagnetic foundations and the radar range equation to predict system performance
• Design aperture and array antennas using radiation integrals and pattern synthesis
• Implement phased-array beamforming and understand grating lobes, tapering, and scan loss
• Analyze radar cross section and scattering for target and clutter modeling
• Select waveforms using the ambiguity function and apply matched filtering for pulse compression
• Build the complete FMCW chirp chain, from sweep linearity to range-Doppler processing
• Mitigate clutter with Doppler processing and MTI filters
• Detect targets with CFAR and estimate angle using monopulse and MIMO techniques
• Track targets with Kalman filters and form SAR images for high-resolution sensing

Who this book is for: RF and DSP engineers, graduate students, and automotive sensing teams who need the physics and the algorithms in the same volume. If you work with radar hardware, write signal processing code, or study remote sensing, this book gives you the end-to-end understanding to design, simulate, and debug modern radar systems.

You can pass a transport course and still freeze in front of a blank flowsheet. This book closes that gap.

Chemical engineering fundamentals are often taught as separate subjects—fluid mechanics here, heat transfer there, thermodynamics somewhere else—leaving students and early-career engineers without a clear path from theory to a working process design. Chemical Process Design Principles bridges that gap by walking through the elementary foundations of transport, separation, metallurgy, and plant economics in one coherent sequence. You will set up material balances with recycle and purge, carry energy balances through reacting systems, size pipe and pumps with real friction and suction-head limits, and design a shell-and-tube exchanger from an overall coefficient and a corrected log mean temperature difference.

Distillation is built from equilibrium to McCabe-Thiele stages, minimum reflux, and column hydraulics, then extended to absorption, extraction, evaporation, and drying. Reactor sizing, a metallurgy chapter on phase diagrams, reduction thermodynamics, and corrosion-resistant alloy choice, and a closing block on flowsheets, capital cost estimation, cash flow, and hazard review complete the design picture. Each chapter connects directly to the next, so you finish with a working understanding of how unit operations fit into a complete process rather than a collection of isolated equations.

What you will learn:

• Apply dimensional analysis and consistent units to process variables and design calculations
• Set up material balances on non-reacting and reacting systems, including recycle and purge streams
• Carry energy balances and thermochemistry through reacting and non-reacting processes
• Use phase equilibrium and physical property data to support separation and reactor design
• Size pipe, pumps, and fluid movers with real friction and suction-head limits
• Design shell-and-tube heat exchangers using overall coefficients and corrected LMTD
• Build distillation designs from equilibrium stages to McCabe-Thiele, minimum reflux, and column hydraulics
• Extend mass transfer fundamentals to absorption, stripping, extraction, leaching, evaporation, drying, crystallisation, and mechanical separation
• Size reactors and select materials using phase diagrams, reduction thermodynamics, and corrosion-resistant alloy choice
• Read and create flowsheets, estimate capital costs, evaluate cash flow, and apply hazard review

Written for chemical and process engineering students and early-career plant engineers, this book is for anyone who needs to move from passing exams to producing defensible process designs. If you are preparing for a design course, starting a plant assignment, or returning to fundamentals after time in the field, the chapters here give you the elementary foundations and the confidence to fill in that blank flowsheet.

Structure decides everything. This book keeps that connection in view from the first bond to the final material selection.

Why does quenched steel crack, and annealed copper bend forever? Because the arrangement of atoms, defects, and phases controls every property an engineer can measure. Materials Science and Engineering Principles builds that understanding as one continuous argument rather than a catalogue of facts. You begin with atomic bonding, crystal structures, and crystallography, then examine imperfections and diffusion before using dislocations to explain yielding, work hardening, and every strengthening mechanism in real use.

The middle of the book turns theory into practice. You read phase diagrams with the lever rule, take the iron-carbon system through transformation curves into practical heat treatment, and follow the same logic into cast irons, aluminium alloys, ceramics, glasses, polymers, and composites. Failure chapters cover fracture toughness, fatigue crack growth, and creep, while the closing chapters address corrosion mechanisms, protection methods, and a structured procedure for choosing a material and its process together. Worked numbers appear throughout, from diffusion depths to laminate stiffness, so the equations stay tied to components you can picture.

What you will learn

• How atomic bonding and crystal structure set the stage for every later property
• How point, line, and planar defects control real material behaviour
• How diffusion drives processes from carburising to sintering
• How dislocations explain yielding, work hardening, and strengthening mechanisms
• How to read phase diagrams and apply the lever rule with confidence
• How iron-carbon transformation curves translate into practical heat treatment
• How fracture toughness, fatigue crack growth, and creep lead to failure
• How ceramics, glasses, polymers, and composites differ in structure and processing
• How to select a material and its manufacturing process as one integrated decision

Written for engineering undergraduates and design engineers specifying materials, this book assumes only introductory chemistry and mechanics. Each chapter connects structure to processing to performance, giving you the reasoning to predict behaviour instead of memorising tables. Whether you are preparing for a materials course, supporting a design project, or returning to the subject from industry, the integrated approach helps you choose alloys, treatments, and processes with evidence rather than habit.

L’histoire captivante d’une femme de science d’exception En 1930, à l’âge de 23 ans, Marcelle Gauvreau réalise un herbier dans le cadre d’un concours organisé par Le Devoir. On souligne dans les pages du quotidien que son projet, un premier effort de communication du savoir, « révèle une vraie vocation». Cette vocation la portera toute sa vie. Elle sera la première femme francophone à décrocher une maîtrise en science au Québec, contribuera à la Flore laurentienne et établira une école pour les tout-petits consacrée à la nature. Marcelle Gauvreau s’inscrit ainsi parmi les pionniers et pionnières d’une époque où la science en français au Québec est encore à se structurer. Or, ses accomplissements, réalisés dans un contexte où les femmes étaient souvent reléguées à des rôles subalternes, tombent peu à peu dans l’oubli. Pour donner à lire la richesse de la vie et de l’époque de Marcelle, cet ouvrage adopte la forme d’un journal intime imaginé, appuyé sur des documents d’archives et des entrevues inédites. Il met en lumière une scientifique québécoise de génie, trop longtemps restée dans l’ombre de son mentor et de ses pairs, et contribue à lui rendre aujourd’hui la place qui lui revient. Surtout, il nous montre le rôle que Marcelle Gauvreau et tant d’autres femmes ont joué, par de grands gestes comme par de minutieux labeurs, dans l’évolution du Québec.

A structure does not care whether you modelled it as a lumped mass or a continuum; it responds at the frequencies it has.

This book takes you from a single spring and mass to measured spectra on real hardware without breaking that chain. You will derive frequency response functions and extract damping from half-power bandwidth, design isolators against transmissibility targets, tune a mass damper, assemble and solve multi-degree-of-freedom systems in modal coordinates, and handle beams, plates and dispersive bending waves. Random vibration then gives you power spectral density, root-mean-square response and fatigue damage estimation, followed by the spectral analysis choices — sampling, windows, averaging — that decide whether your measurement means anything. Closing coverage includes modal testing and active control.

For graduate students, structural dynamicists and test engineers, the treatment balances theory, modeling, measurement and spectral analysis so that each concept connects directly to the next. Derivations are presented with enough detail to follow by hand, while numerical methods and finite element vibration are introduced where they become necessary. The result is a coherent path from first principles to practical implementation.

What you will learn:

• Derive the free vibration response of single-degree-of-freedom systems and identify natural frequency and damping ratio from physical parameters.
• Extract damping from half-power bandwidth and interpret frequency response functions for harmonic excitation.
• Design vibration isolators against transmissibility targets and analyze base excitation and unbalance.
• Tune a mass damper and solve two-degree-of-freedom systems for absorber performance.
• Assemble and solve multi-degree-of-freedom systems in modal coordinates, including numerical methods and finite element vibration.
• Model continuous systems, beams and plates, and analyze dispersive bending waves in structures.
• Estimate random vibration response using power spectral density, root-mean-square values and fatigue damage.
• Make spectral analysis choices — sampling, windows, averaging — that determine measurement validity.
• Apply modal testing and active control techniques to real hardware.

This book is for graduate students, structural dynamicists and test engineers who need a rigorous yet practical treatment of mechanical vibrations, from theory and modeling to measurement and spectral analysis.

A comprehensive guide to finite element theory and simulation with ANSYS Workbench, covering static, dynamic, and fluid analysis with practical case studies.

A hands-on guide to designing, installing, and maintaining off-grid and hybrid solar power systems for cabins, RVs, vans, and boats, with real numbers instead of guesswork.

You already know your organisation behaves in ways nobody intended. This book gives you the tools to show why.

System dynamics is not a software feature or a diagramming habit. It is a disciplined way of representing how accumulation, feedback, and delay produce the behaviour you observe—and of testing whether your explanation survives contact with data. This book teaches that discipline from the ground up, using the conventions and pitfalls that separate a model you can defend from a sketch that merely looks plausible.

You begin by drawing reference modes and framing a dynamic hypothesis, then learn causal loop diagrams properly, with polarity and naming rules that keep a diagram readable a month later. From there you convert structure to stocks, flows and equations, choose an integration step that does not fabricate behaviour, and model material and information delays. You build growth, oscillation and overshoot structures, calibrate nonlinear relationships, test models with extreme-condition and dimensional checks, and run sensitivity sweeps. Four complete models, from inventory and workforce to an energy transition, are developed end to end.

What you will learn:

• Frame a dynamic hypothesis and draw reference modes that define what a model must explain
• Build causal loop diagrams with correct polarity, loop naming, and readable layout
• Translate feedback structure into stocks, flows, and equations without losing meaning
• Select integration steps and time constants that do not manufacture oscillation or overshoot
• Represent material and information delays, including pipeline and perceptual delays
• Construct and diagnose growth, oscillation, and overshoot structures
• Calibrate nonlinear table functions and avoid common curve-fitting errors
• Validate models with extreme-condition, dimensional, and sensitivity tests
• Develop four complete models: inventory, workforce, and an energy transition

For analysts, operations managers and engineers who must model complex systems before deciding, this book is a practical bridge from whiteboard to simulation. If your decisions depend on how stocks accumulate, how feedback loops interact, and how delays surprise you, the methods here will change both what you build and what you trust.

Stop copying settings. Start understanding sound.

Most recording advice is a list of settings that worked once in someone else's room. This book gives you the reasons instead, so the settings follow. You will learn how level, wavelength and room modes decide what a microphone can capture, why two microphones on one source comb filter and how to place them so they do not, and how polar patterns and proximity effect change a tone before any processing happens.

From there you work through gain staging, converters, latency, compression time constants, filter behaviour, reverb parameters and a full mix structure with automation and monitoring discipline. Closing chapters cover loudspeaker directivity, monitor placement, live reinforcement, system alignment and gain before feedback. For audio engineers, students and studio operators who want the physics behind the practice.

What you will learn:

• How sound level, the decibel and psychoacoustics shape every recording decision
• How room acoustics and treatment control what reaches the microphone
• How polar patterns, proximity effect and microphone technique alter tone before processing
• How stereo and immersive capture techniques create width and depth without phase problems
• How signal flow, impedance and gain staging keep noise low and headroom intact
• How digital audio, converters and latency affect tracking in the DAW
• How compression time constants, equalisation and filters work on real sources
• How reverb, delay and modulation parameters build space and movement
• How to structure a mix with automation, monitoring discipline and loudspeaker directivity in mind

Whether you are an audio engineer, a student of recording, or a studio operator moving between the control room and live sound, this guide connects the physics to the practice. If you want to make decisions from understanding rather than memory, this book is for you.

Every transistor specification is the consequence of a band diagram. This book makes that chain explicit, from crystal physics to the packaged chip.

You will build carrier statistics and transport from band structure, derive junction behavior and breakdown, and follow minority carriers through a bipolar transistor before constructing the metal-oxide-semiconductor capacitor that underlies everything modern. Transistor chapters carry you from long-channel current equations to subthreshold slope, drain-induced barrier lowering and the leakage that ended simple scaling, then into high-permittivity gate stacks, strain, fin and nanosheet devices. Memory, power and optoelectronic chapters widen the scope. Fabrication chapters connect the physics to lithography, etch, implantation and deposition, and closing chapters cover interconnect delay, advanced packaging, compact models, yield and reliability.

Written for electrical engineering students, device and process engineers, and semiconductor professionals, this book bridges the gap between abstract physics and practical chip design. Each chapter builds on the previous one, ensuring a coherent progression from fundamental principles to advanced topics. Whether you are new to the field or seeking to deepen your expertise, this text provides the rigorous foundation needed to understand and innovate in modern semiconductor technology.

What you will learn:

• How energy bands and carrier statistics govern semiconductor behavior
• The mechanisms of doping, drift, diffusion, and carrier transport
• Generation, recombination, and the role of excess carriers
• PN junction operation, including depletion, bias, and breakdown
• Metal-semiconductor contacts and heterojunctions
• Bipolar junction transistor physics and minority carrier action
• MOS capacitor behavior and threshold voltage determination
• MOSFET current-voltage characteristics and short-channel effects
• Modern device structures: high-permittivity gates, FinFET, and nanosheet
• Fabrication processes: lithography, etch, implant, and deposition
• Interconnect, packaging, compact models, yield, and reliability

This book is ideal for electrical engineering students at the advanced undergraduate or graduate level, device and process engineers in the semiconductor industry, and professionals seeking a comprehensive reference on semiconductor device fundamentals. It assumes a basic background in physics and calculus, but builds all necessary concepts from the ground up.

A backup system either carries your loads through the outage or it does not, and the difference is arithmetic you can do yourself.

This guide walks you through that arithmetic step by step, from the first load audit to the final commissioning check. You will measure real appliance draw and build an honest watt-hour budget, size an array from peak sun hours, correct string voltage for the coldest morning of the year, and choose a maximum power point controller that matches it. No hand-waving, no rule-of-thumb shortcuts that fail in February.

You will compare lithium iron phosphate and lead-acid banks, size amp-hours to your runtime, decide between 12, 24 and 48 volt buses, select inverter continuous and surge ratings, and size conductors, fuses, disconnects and bonding correctly. Closing chapters cover the critical loads subpanel, transfer switching, permits, commissioning and fault finding. Written for capable homeowners, cabin and van builders, and new solar installers who want a system that works when the grid does not.

What you will learn:

• Four ways to build a backup system and how to choose the right architecture for your site
• How to run a load audit that measures real appliance draw and produces an honest watt-hour budget
• How to size a solar array from peak sun hours and correct string voltage for the coldest morning of the year
• How to select and configure a maximum power point charge controller that matches your array and bank
• How to compare lithium iron phosphate and lead-acid batteries and size amp-hours to your required runtime
• How to choose between 12, 24 and 48 volt buses and select inverter continuous and surge ratings
• How to size conductors, overcurrent protection, disconnects, grounding and bonding correctly
• How to connect to the house with a critical loads subpanel and transfer switching, including permits
• How to commission, monitor, maintain and troubleshoot the system once it is running

This book is for capable homeowners, cabin and van builders, and new solar installers who want a backup system that carries the loads that matter. If you can read a multimeter and follow a wiring diagram, you can build and maintain the system described here.

Reinforced concrete design goes wrong in the details, not the formulas.

This book builds the mechanics first, deriving the stress block from strain compatibility so you know exactly why a section is tension-controlled, then carries each limit state through to a finished bar schedule. You will design beams in flexure, size stirrups for shear and torsion, calculate development lengths and place cutoffs correctly, control cracking and long-term deflection, construct column interaction diagrams, handle slenderness and moment magnification, and design one-way and two-way slabs including punching shear. Footings and retaining walls follow, with a closing set of licensing-exam problems worked in full under current code provisions.

Every chapter connects theory to practice: start with material behavior and design philosophy, move through flexural analysis and design of rectangular and flanged beams, then tackle shear, torsion, bond, development, and splices. Serviceability, short and slender columns, continuous beams, one-way and two-way slabs, footings, and retaining walls are covered with step-by-step procedures and code-referenced checks. The final chapter integrates systems and provides exam-style practice problems solved in full, so you can verify your understanding and build speed for the structural depth exam.

What you will learn:

• Derive the equivalent stress block from strain compatibility and identify tension-controlled, transition, and compression-controlled sections.
• Analyze and design rectangular and flanged beams for flexure, including reinforcement selection and detailing.
• Size stirrups and design for shear and torsion using ACI 318-25 provisions.
• Calculate development lengths, lap splices, and bar cutoffs, and apply proper detailing rules.
• Control cracking and long-term deflection through serviceability checks.
• Construct column interaction diagrams and handle slenderness and moment magnification.
• Design one-way and two-way slab systems, including punching shear reinforcement.
• Proportion footings and retaining walls for stability and strength.
• Work licensing-exam problems in full, from load takedown to final design.

For structural engineering students, design office engineers, and candidates preparing for the structural depth exam, this book provides a rigorous yet practical path to mastering reinforced concrete analysis and design under current code provisions.

You can read a midship section, but could you build one?

This guide walks you through a steel hull from raw plate to sea trials. You will learn how class rules set scantlings, how plate is nested, cut and formed, and how to choose between stick, flux-cored, MIG and submerged arc welding for each joint in the yard. You will set preheat and heat input, qualify a procedure and a welder, control distortion with sequencing and flame straightening, and judge welds by ultrasonic and radiographic results.

Structural chapters take you through double bottoms, framing, bulkheads, stern frames and superstructure, then coatings, cathodic protection, launching and trials. Closing chapters cover work breakdown, scheduling and man-hour control. Written for naval architecture students, welding inspectors, hull trades supervisors and shipyard project engineers.

What you will learn:

• Interpret class rules and statutory requirements to determine scantlings and gain drawing approval
• Prepare, mark, cut and form steel plate efficiently in a shipyard production environment
• Select and apply arc welding processes—stick, flux-cored, MIG and submerged arc—for specific hull joints
• Qualify welding procedures and welders, and set preheat and heat input parameters
• Control distortion and residual stress using sequencing and flame straightening techniques
• Evaluate weld quality through ultrasonic and radiographic non-destructive examination
• Construct bottom structure, sides, frames, decks, bulkheads, bow, stern and appendages
• Install superstructure, outfit machinery, and apply corrosion protection and coatings
• Manage shipbuilding projects from work breakdown and scheduling to man-hour control and sea trials

Whether you are a naval architecture student, a welding inspector, a hull trades supervisor, or a shipyard project engineer, this book provides the practical knowledge to build and weld ships from the ground up.

You already know your codebase is hard to change. This book tells you which decisions made it that way and what to do next.

Software structure is not a matter of taste. It is a set of decisions about coupling, cohesion, and dependency direction that determine how much every future change will cost. Software Structure by Design is a practical handbook for developers, tech leads, and anyone inheriting a codebase they did not design. It shows you how to read the structure you have, understand why it resists change, and reshape it without stopping delivery.

The book moves from principles to boundaries to the hard work of making structure stick. You will learn to treat coupling and cohesion as a cost you can measure, invert dependencies so frameworks and databases sit at the edges instead of the centre, and draw component boundaries that survive a release. Separate chapters handle the database boundary, the web boundary, and the honest trade between a modular monolith and services. Then you make the structure durable with fitness checks, the humble object pattern, characterisation tests, strangler migrations, and decision records. A complete worked application runs through every boundary at the end, tying the techniques together.

What you will learn:

• Read coupling and cohesion as a cost, not an abstraction, and use that reading to prioritise refactoring
• Apply paradigms as constraints that shape design rather than as academic rules
• Put design principles to work in real code, including dependency inversion and stable abstractions
• Draw component boundaries that hold up across releases and team changes
• Design the domain layer so business rules stay independent of delivery mechanisms
• Place the database and the web/UI at the edges with clear, testable boundaries
• Choose between a modular monolith and services based on honest trade-offs, not fashion
• Test the architecture itself with fitness checks, characterisation tests, and the humble object pattern
• Refactor toward structure safely using strangler migrations and document decisions so the structure survives

Written for developers, tech leads, and architects who need to improve an existing system rather than start from a blank page, this book assumes you can write code and want to make the code you have easier to change. If you are responsible for a codebase that has grown beyond its original design, this handbook gives you a clear path from diagnosis to durable structure.

On exam day you will not be rewarded for deriving anything. You will be rewarded for recognising the problem type, finding the right equation in the reference handbook and substituting cleanly under time pressure. This book trains exactly that.

Every worked solution names the handbook section it comes from, shows the substitution in full, checks units and explains why the near-miss answers are wrong. You get drilled coverage of circuits, linear systems, electronics, power, electromagnetics, digital and computer systems, control, mathematics, statistics, economics and ethics, with hundreds of problems timed to exam pace and a full-length practice exam to finish.

For electrical and computer engineering students and working engineers sitting the FE computer-based exam, this book is built around the way the CBT actually tests you: fast recall, confident handbook navigation and clean arithmetic. Instead of long derivations, each chapter walks through the problem types that appear on the exam, points to the exact reference handbook section, and shows the full substitution step by step. Unit checks are built into every solution, and the distractors are explained so you learn to spot the trap answers before you commit to them.

What you will learn:

• How the CBT exam is structured and how to navigate the supplied reference handbook quickly
• Mathematics and probability and statistics problems solved at exam pace
• Ethics and professional practice questions, plus engineering economics calculations
• Properties of electrical materials and how they are tested
• DC and AC circuit analysis, linear systems and signal processing
• Electronics, power systems and electromagnetics problem types
• Digital systems, computer systems and software questions
• Control systems problems and full-length timed practice under exam conditions

This book is for electrical and computer engineering students preparing for the FE exam, working engineers returning to the fundamentals before sitting the CBT, and anyone who wants a structured, solution-driven way to practise rather than a passive review of theory.

La véranda est aujourd’hui un véritable espace de vie, ouvert vers l’extérieur, généralement chauffé, aménagé et parfaitement intégré à la maison.

Ouvrage à part entière, la véranda peut – et dans beaucoup de cas, doit – atteindre les mêmes performances d’habitabilité et de confort qu’un bâti classique : technique de toiture, parois verticales, stabilité, jonctions avec le gros œuvre, jonctions avec le sol, thermique d’hiver, thermique d’été, étanchéité à l’eau, perméabilité à l’air, performances acoustiques, sécurité, installation électrique, accessibilité, etc.

Autant de contraintes fortes à satisfaire pour obtenir un ouvrage de qualité permettant d’atteindre les performances attendues, de respecter l’usage prévu et de prévenir les désordres.

En matière de véranda, c’est donc essentiellement de la qualité de l’enveloppe que vient la qualité d’usage et d’habitabilité du local ainsi créé.

Cette nouvelle édition prend en compte les évolutions des règles de l’art de la profession. Elle propose une revue des normes et réglementations en vigueur, d’une part, et des exigences sur la conception thermique de la véranda, d’autre part.

Le guide s’intéresse à l’enveloppe de la véranda, à sa conception, à son implantation, à sa fabrication, à sa mise en œuvre et à son entretien.

Le guide s’appuie sur les Règles professionnelles « Vérandas à ossature aluminium » éditées par le SNFA et sur les Règles d’attribution de l’attestation de conformité de la conception des systèmes de vérandas mises au point et développées par le CSTB.

Fruit d’une collaboration entre enseignants-chercheurs de l'université Paris-Saclay et ingénieurs (Renault, Stellantis, Valéo…), cet ouvrage offre aux techniciens et étudiants en construction et maintenance automobile les ressources indispensables pour comprendre et intervenir sur les technologies des véhicules électriques. 
Richement illustré (un véhicule sera même démonté afin que ses différents composants puisse être photographiés) et structuré de manière à faciliter un apprentissage sans pré-requis spécifiques, il permet une découverte progressive des composants, des architectures et des principes de fonctionnement des véhicules électriques, du véhicule urbain léger au camion.
Il accompagnera ainsi les évolutions des métiers de la maintenance, de la conception et du diagnostic dans un secteur en pleine mutation.

Most systems fail at their seams, not their parts. This handbook teaches the discipline that holds the seams together.

Requirements Analysis and Model-Based Design is a practical handbook for designing complex systems using modern principles. It walks you from stakeholder needs and an operational concept through verifiable requirements, traceability, functional analysis, interface control, and architecture allocation. You then move into a full model-based treatment: block definition, internal block, activity, state machine, and parametric diagrams assembled into one coherent model instead of a shelf of documents that disagree.

Trade study chapters give you weighted decision analysis, and risk chapters give you registers and technical performance measures that track margin honestly. Verification chapters cover inspection, analysis, demonstration, and test, along with integration sequencing and review gates. One communications system runs through every chapter, so each method is shown in context rather than as an isolated technique. The result is a repeatable path from needs to a verified, integrated system.

What you will learn:

• Apply systems thinking across the full system life cycle
• Capture stakeholder needs and write a concept of operations
• Elicit and write requirements that can actually be verified
• Manage requirements, traceability, and baselines across a multi-year program
• Perform functional analysis and behavioural modelling
• Define architecture and synthesize design through allocation
• Control interfaces, boundary documents, and system seams
• Build SysML models: block definition, internal block, activity, state machine, and parametric diagrams
• Use parametric models, simulation, and the digital thread
• Run trade studies and weighted decision analysis
• Manage risk, opportunity, and technical performance measures
• Plan verification, validation, and test, including inspection, analysis, demonstration, and test
• Sequence integration, technical reviews, and configuration management
• Address reliability, specialty engineering, and life-cycle support

For engineering students and practitioners new to systems roles, this handbook provides a coherent method you can apply immediately. If you are moving from a component-focused role into systems engineering, or studying systems engineering and want a practical reference that connects requirements, architecture, and models, this book is for you.

A road fails where the design, the mixture and the roller meet, so this book covers all three.

Asphalt and Subgrade Pavement Design is a complete, practice-oriented guide to modern road materials, construction technology and durability analysis. It begins at the ground beneath the road, showing you how to classify and stabilise a subgrade, interpret California bearing ratio and resilient modulus results, and design drainage that keeps water out of the structure. From there it moves upward through aggregates and unbound layers, performance-graded binders, volumetric mixture design, and the performance tests that reveal rutting, fatigue, moisture damage and thermal cracking before they appear on the road.

Construction chapters follow the material from plant to pavement: production, warm-mix technology, segregation control, joints, rolling patterns and density acceptance. The book then shows how to size a structure by both empirical and mechanistic-empirical methods, compute equivalent axle loads, interpret deflection testing, identify distresses in the field, and design recycling, preservation and overlay treatments. Concrete pavements, traffic loading and load spectra, and pavement management complete the picture, giving engineers and students a single reference that connects soil, mix, construction and structural performance.

What you will learn:

• Classify and stabilise subgrade soils, and interpret CBR and resilient modulus results
• Design drainage and frost protection that keep water out of the pavement structure
• Select performance-graded asphalt binders for a given climate and traffic level
• Run a volumetric mixture design and test for rutting, fatigue, moisture damage and thermal cracking
• Manage plant production, warm-mix technology, segregation, joints, rolling patterns and density acceptance
• Size flexible pavements by empirical and mechanistic-empirical methods
• Compute equivalent axle loads and interpret deflection testing
• Identify pavement distresses in the field and plan recycling, preservation and overlay treatments
• Apply pavement management principles to maintenance and rehabilitation decisions

Written for highway and materials engineers, technicians and civil engineering students, this book is equally suited to practising professionals who need a current reference on pavement design and construction, and to students building a foundation in transportation infrastructure.

Recognize the problem type in ten seconds. Solve it in five minutes. That is the reflex this book builds.

The NCEES Civil PE Water Resources and Environmental depth exam rewards speed and judgment as much as calculation. Civil PE Water and Environmental Practice Exams trains you to see a problem, name the governing equation, and execute cleanly under time pressure. Compact reviews cover pipe and channel hydraulics, pump and system curves, rainfall-runoff and detention routing, groundwater drawdown, coagulation through disinfection contact time, activated sludge loading, collection systems, and engineering economics—each written to the depth the exam actually reaches, not to textbook excess.

Then you practice. Conceptual items test judgment rather than arithmetic. Two full-length depth examinations follow, with step-by-step solutions that name the equation, carry the units, and explain why the tempting wrong answer is wrong. Pacing guidance runs throughout, so you learn when to solve, when to estimate, and when to move on.

What you will learn:

• How the depth exam is structured and how to build a preparation plan that fits your schedule
• Fluid mechanics fundamentals as they appear in exam problems
• Closed conduit hydraulics: friction losses, minor losses, and pipe networks
• Open channel flow: Manning equation, specific energy, and hydraulic jumps
• Hydrology: rainfall-runoff relationships, unit hydrographs, and detention routing
• Groundwater and wells: drawdown, well hydraulics, and aquifer testing
• Water treatment: coagulation, sedimentation, filtration, and disinfection contact time
• Wastewater treatment and collection: activated sludge loading and collection system hydraulics
• Stormwater management and engineering economics for water projects

For civil engineering candidates sitting the water resources and environmental depth exam, this book is your focused, practical companion. If you need to convert knowledge into exam-day speed, this is the training you want.

Stop blaming your solver. Start understanding why it fails.

A solver that converges on the textbook problem and stalls on yours is the usual experience. This book explains why and what to do. You will see how conditioning wrecks steepest descent, how quasi-Newton updates recover curvature without a Hessian, and when a trust region beats a line search. You will compute derivatives by finite differences, complex-step, automatic differentiation and adjoints, then move into constrained problems through the Karush-Kuhn-Tucker conditions, duality, augmented Lagrangians, sequential quadratic programming and interior-point methods. Later chapters cover surrogate and Bayesian search, Pareto trade-offs, structural and topology optimisation, dynamic programming, the linear quadratic regulator and model predictive control, and close on regularised inverse problems and the stochastic gradient methods behind modern learning.

Written for engineers, applied mathematicians and graduate students who build and tune solvers, this book connects numerical optimisation theory to the practical decisions that determine whether an algorithm converges, how fast, and to what. Each method is motivated by the failure mode it addresses, so you learn not just the update formula but the diagnostic reasoning that tells you which tool fits the problem in front of you.

What you will learn:

• Formulate optimisation problems with clear objectives, constraints and scaling
• Diagnose conditioning and choose between line search, Newton and quasi-Newton updates
• Apply conjugate gradient and trust-region methods to large and ill-behaved problems
• Compute derivatives by finite differences, complex-step, automatic differentiation and adjoints
• Solve constrained problems with KKT conditions, duality, SQP and interior-point methods
• Use derivative-free, stochastic and surrogate methods, including Bayesian search
• Optimise engineering designs, including structural and topology optimisation
• Apply dynamic programming, LQR and model predictive control to optimal control
• Regularise inverse problems and understand stochastic gradient methods for machine learning

This book is for engineers, applied mathematicians, quantitative scientists and graduate students who need to build, tune and trust optimisation solvers in real applications. If you work at the boundary of numerical methods, engineering design, control and machine learning, the chapters give you the theory and the practical judgement to move from a method that almost works to one that reliably does.

Lubrication chapters cover viscosity selection, contamination control, cleanliness coding and oil analysis interpretation. Condition monitoring chapters teach vibration spectra, thermography and ultrasound routes with practical alarm limits. Final chapters turn all of it into strategy: task selection, planning, spares policy and downtime accounting.

What you will learn:

• Reliability language and metrics that withstand scrutiny
• How to build an asset hierarchy that preserves failure history
• Failure modes of rotating equipment: bearings, gears, seals, couplings

Cette question se pose aujourd’hui à chacune et à chacun d’une manière urgente, et se posera d’une manière plus urgente encore dans les mois et dans les années à venir. Il ne s’agit pas seulement de savoir comment conserver son travail, mais également comment survivre dans ce nouveau monde. Nous sommes aujourd’hui à la veille d’une transformation radicale, peut-être comparable aux plus grands bouleversements technologiques du passé.

L’objectif de ce livre est de guider les lecteurs et lectrices dans ce nouveau monde. Pour commencer, en leur donnant les clés pour comprendre exactement ce en quoi consiste la technologie rendant possible ces innovations révolutionnaires, d’une manière précise et technique mais toujours accessible. Ensuite, en corrigeant les lieux communs qui obscurcissent le paysage et empêchent de comprendre comment utiliser correctement ces machines. Enfin, en donnant la parole à quelques-uns des explorateurs et exploratrices de ce nouveau monde, qui nous expliquent quelles compétences, mais aussi quelles vertus (honnêteté, patience, prudence…), nous permettront d’y prospérer.

Process safety is not a chapter at the back of chemical engineering. It is the reason most of the design equations exist.

This reference puts the two together, section by section, in the order a practising engineer works. You will find the property data and estimation methods your calculations rest on, reactor design equations extended into thermal stability and runaway criteria, flammability and ignition behaviour, source terms and dispersion, fire and explosion consequences, and relief sizing including two-phase scenarios.

Hazard identification, fault and event trees, layer of protection analysis and inherently safer design follow, each with worked numbers rather than description alone, and the closing chapter supplies PE-format problems mapped back to every section. For chemical engineers in design and operations and for PE candidates.

What you will learn:

• Apply process safety management principles and risk concepts to real plant decisions
• Estimate physical properties and use them correctly in hazard calculations
• Use material and energy balances as diagnostic tools for abnormal situations
• Extend chemical reaction engineering fundamentals to thermal stability and runaway criteria
• Evaluate flammability limits, ignition behaviour, and their impact on safe operation
• Model source terms and dispersion for accidental releases
• Assess fire and explosion consequences with practical methods
• Size pressure relief systems, including two-phase flow scenarios
• Perform hazard identification, quantitative risk analysis, and layer of protection analysis
• Apply inherently safer design and plant layout principles
• Solve PE-format problems mapped to each section of the handbook

This book is for chemical engineers in design and operations who need a working reference that connects fundamentals to process safety, and for PE candidates preparing for the chemical engineering exam. It assumes a background in chemical engineering principles and provides worked numbers, not just descriptions, so you can apply the methods directly.

A practical beginner's workbook for reading hydraulic schematics, calculating circuits, and troubleshooting mobile machinery.

Astrodynamics is not hard because the ideas are strange; it is hard because one skipped substitution wrecks the answer. This workbook shows every step.

You set up frames and time systems properly, derive the two-body result, convert state vectors to elements and back, solve Kepler's equation by iteration, and build a delta-v budget from Hohmann transfers and plane changes. Then you take on rendezvous with Clohessy-Wiltshire, Lambert targeting with porkchop plots, gravity assists by patched conics, J2 drift used deliberately to design a sun-synchronous orbit, and orbit determination from real observation types. Four full mission case studies close the book.

Written for aerospace students, self-taught mission analysts and engineers preparing for spaceflight design work, this illustrated workbook treats every derivation as a sequence of checkable steps. Each chapter pairs the governing equations with worked numerical examples, so you can follow the algebra from first principles to a final answer and see exactly where a sign error or a unit slip would change the result. The mission case studies tie the individual techniques together into end-to-end design exercises.

What you will learn:

• Set up reference frames and time systems correctly before any orbit calculation
• Derive the two-body problem and convert between state vectors and orbital elements
• Solve Kepler's equation by iteration and compute time of flight for elliptic, parabolic and hyperbolic orbits
• Build delta-v budgets from impulsive manoeuvres, Hohmann transfers and plane changes
• Analyse rendezvous and relative motion using the Clohessy-Wiltshire equations
• Solve Lambert's problem and read porkchop plots for interplanetary transfer
• Apply patched conics and gravity assists to design planetary flybys
• Use J2 drift deliberately to design sun-synchronous and other special orbits
• Perform orbit determination from real observation types and close the loop with four full mission case studies

This book is for aerospace engineering students taking a first or second course in orbital mechanics, for self-taught mission analysts who need the missing steps, and for practising engineers moving into spaceflight design work who want a single illustrated reference that connects theory to mission planning.

Stop memorizing formulas. Start solving problems with confidence.

Certification exams test arithmetic under pressure and process judgement you can defend on shift. This review builds both. You will drill conversions, flow, detention time, loading rates and the pounds formula until the setup is automatic, then work through coagulation and jar testing, sedimentation and filtration rates, chlorine demand, breakpoint and contact time credit, ultraviolet dose and corrosion control. Distribution chapters cover head loss, pump horsepower, storage turnover, cross-connection control and main disinfection. Wastewater chapters take you through lift stations, primary clarifiers, and activated sludge control by mixed liquor solids, food-to-microorganism ratio, mean cell residence time and sludge volume index, then fixed-film systems, nutrient removal, digestion, dewatering and biosolids. Laboratory, reporting, safety chapters and two full practice exams finish the book.

Written for water and wastewater operators at every certification grade, this guide connects each calculation to the process it controls. You will move from basic unit conversions to complex process control scenarios, learning not just how to solve a problem but why the answer matters for plant performance and permit compliance. Each chapter includes worked examples, practice questions, and clear explanations that reinforce the math and the operational logic behind it.

What you will learn:

• Master operator mathematics: conversions, flow, detention time, loading rates, and the pounds formula
• Apply coagulation, flocculation, sedimentation, and filtration calculations in water treatment
• Calculate chlorine demand, breakpoint, contact time credit, UV dose, and corrosion control parameters
• Solve distribution problems: head loss, pump horsepower, storage turnover, and cross-connection control
• Operate collection systems, lift stations, and preliminary treatment with confidence
• Control activated sludge using MLSS, F/M ratio, MCRT, and SVI
• Manage fixed-film, lagoon, and nutrient removal processes
• Handle solids: digestion, dewatering, and biosolids calculations
• Prepare for lab, sampling, permits, reporting, safety, and maintenance responsibilities

This book is for water and wastewater operators preparing for certification exams at any grade, from entry-level to advanced. Whether you are new to the field or upgrading your license, the focused review and practice exams will help you build the speed and accuracy needed to pass and the process understanding to excel on the job.

Between the laser and the recovered bit sit a dozen circuits that must all meet budget. This book designs them with you.

An optical transceiver is not one invention but a chain of compromises: a laser that must be biased, modulated and kept cool; a driver that must swing fast without ringing; a photodiode whose every stray picofarad costs sensitivity; a transimpedance amplifier pushed against the transimpedance limit; and a clock recovery loop that must lock onto a signal already blurred by jitter and dispersion. Each stage has its own budget, and a link only closes when every one of them does. This book works through that chain from first principles, with the equations and the practical numbers side by side.

You will begin with the optical link budget and the fibre propagation limits that set the target, then work through laser rate equations to understand chirp, relaxation oscillation and noise, and use that understanding to choose between direct modulation, electroabsorption and Mach-Zehnder drive. On the receive side you will select PIN or avalanche detection, size a shunt-feedback transimpedance amplifier against the transimpedance limit and its input-referred noise, chain limiting stages, cancel offset, and close a clock recovery loop that survives real jitter. Later chapters extend the design to equalisation and four-level signalling, silicon photonic waveguides, couplers and ring modulators, and the layout, shielding, electrostatic discharge and packaging choices that decide whether a transceiver works on the bench and in the field.

What you will learn

• Build and close an optical link budget from transmitter power to receiver sensitivity
• Apply laser rate equations to chirp, relaxation oscillation and noise in diode laser design
• Compare direct modulation, electroabsorption and Mach-Zehnder drive for a given reach and rate
• Design laser and modulator driver circuits that meet speed and integrity targets
• Choose between PIN and avalanche photodetectors and predict their noise contribution
• Size a shunt-feedback transimpedance amplifier against the transimpedance limit
• Chain post-amplifiers, AGC and offset control without losing dynamic range
• Close a clock and data recovery loop that tolerates real jitter
• Extend a link to equalisation, PAM4 and higher data rates
• Lay out, shield, protect and package a transceiver so it works outside simulation

Written for analog and photonics IC engineers and graduate students, the book assumes comfort with small-signal circuit analysis and basic semiconductor device physics, and takes you from the link budget to the packaged module. It is equally suited to engineers moving into optical communications from wireline or RF design, and to graduate students who need the full signal chain in one place rather than scattered across papers.

En France, les écosystèmes lacustres, qui regroupent plus de huit cent mille plans d’eau, concentrent à la fois une biodiversité remarquable, de multiples usages et des enjeux environnementaux majeurs. Pourtant, dans le contexte actuel de l’Anthropocène — marqué par l’aggravation des crises écologiques — ces milieux figurent parmi les plus menacés au monde, avec un déclin accéléré de leur biodiversité.

Face à ce constat, la science ne peut plus se limiter à décrire et à prédire les évolutions en cours : elle doit aussi accélérer l’appropriation de ses résultats par la société et proposer des solutions concrètes pour limiter, voire inverser, les impacts de ces transformations.

C’est dans cette optique que le Pôle Recherche et Développement Écosystèmes Lacustres (Pôle R&D ECLA), créé en 2009 et renforcé en 2019, agit à l’interface entre recherche et gestion. Porté par un partenariat entre l’Office français de la biodiversité (OFB) et les principales équipes académiques françaises spécialisées en écologie lacustres (INRAE, Université Savoie Mont Blanc), il produit des connaissances et des outils opérationnels pour préserver, restaurer et adapter les lacs aux défis de l’Anthropocène.

Ce numéro présente vingt-trois résultats marquants issus de son programme 2019-2024, organisés en quatre axes principaux : 1) Évaluation et gestion de la biodiversité lacustre ; 2) Impacts du changement climatique et leviers d’atténuation ; 3) Effets de l’anthropisation et solutions de restauration écologique ; 4) Valorisation et transfert des connaissances

A motor nameplate carries everything you need, once you know how to read it.

This book teaches machines from the magnetic circuit up so the numbers mean something. You work transformers from the ideal model through the equivalent circuit to open-circuit and short-circuit tests, regulation and efficiency, then three-phase connections, tap changers and parallel operation. Direct current machines, induction motors, single-phase and special types and synchronous machines each get their magnetic explanation, equivalent circuit and torque-speed behaviour before any application.

You learn across-the-line, wye-delta and soft starting, then variable frequency drive stages, volts-per-hertz and vector control and harmonic effects. Protection, insulation testing, vibration and thermography chapters connect theory to maintenance. Every chapter builds from first principles, with clear explanations and practical context, so you can move from basic electrical fundamentals to the behaviour of complete drive systems.

What you will learn:

• Electrical fundamentals for machines, including power, energy and circuit laws
• Magnetic circuits and core losses, and why they set the limits of machine performance
• Single-phase and three-phase transformers, including equivalent circuits, tests, regulation, efficiency, connections, tap changers and parallel operation
• Autotransformers and instrument transformers for measurement and protection
• Direct current machines: construction, equivalent circuit and torque-speed behaviour
• Three-phase induction motors, plus starting, testing and rating methods
• Single-phase and special machines for applications where three-phase is not available
• Synchronous machines, including their magnetic explanation and operating characteristics
• Variable frequency drives: stages, volts-per-hertz and vector control, and harmonic effects
• Protection, maintenance and testing, including insulation testing, vibration and thermography
• How machines behave inside complete power systems

For electrical technicians, apprentices, maintenance engineers and students meeting machines for the first time, this book provides a complete, beginner-friendly path from magnetic circuits to drives and power systems. If you want to understand what the nameplate really means and how to keep machines running, this is where to start.

L’analyse est au coeur de la pensée mathématique : comment passe-t-on du discret au continu, des entiers naturels aux nombres réels ? Comment décrit-on la régularité d’une suite de nombres et d’une fonction à valeurs réelles ? Comment approche-t-on un nombre ou une fonction ? Voilà quelques-unes des questions fondamentales auxquelles on répond dans cet ouvrage.

On y présente de façon progressive et rigoureuse les concepts centraux de limite, de convergence, de continuité et de dérivabilité. Les principales suites, séries et fonctions numériques ainsi que leurs propriétés sont introduites au fur et à mesure à titre d’exemples. On y annexe des éléments de géométrie pour les fonctions trigonométriques dans le souci de ne rien affirmer sans justification. On y ajoute 109 exercices avec corrigés détaillés pour bien approfondir la matière. Tout est mis en oeuvre pour assurer une entrée réussie dans le monde fascinant de l’analyse mathématique.

Cette introduction à l’analyse s’adresse aux étudiantes et étudiants des filières mathématiques au niveau de la licence (ou du « baccalauréat » selon les pays). Les préalables sont des connaissances de base en calcul différentiel et intégral, en algèbre linéaire et en mathématiques discrètes.

Before you can troubleshoot an instrument, you have to read the drawing that says what it is supposed to do. This book gets you there from the beginning.

Instrumentation for Industrial Process Systems is a practical, ground-up guide for anyone who needs to understand how measurement and control loops actually work in a plant. You will start with the electrical basics that every loop depends on—circuits, power, grounding, and the noise that corrupts a millivolt signal—then learn what accuracy, span, zero, and hysteresis actually cost you in a real measurement. From there you cover pressure, level, temperature, flow, and analytical instruments with their installation rules and failure modes.

The second half of the book turns to the drawings themselves: identification letters, tag numbers, instrument balloons, line conventions, full piping and instrumentation diagrams (P&IDs), loop sheets, and panel wiring. Valves, drives, controllers, and safety systems follow, and a graded workbook with answer keys closes the book. Each chapter builds on the last, so you finish with a working knowledge of both the hardware and the documents that describe it.

What you will learn:

• Electrical fundamentals for instrumentation: circuits, power supplies, grounding, and noise control
• How sensor performance is specified—accuracy, span, zero, hysteresis, and error
• Standard signal types and transmission methods used in process loops
• Pressure, level, temperature, flow, and analytical measurement principles, installation rules, and failure modes
• Instrument identification letters, tag numbers, and P&ID symbols
• How to read process drawings, loop sheets, and panel wiring diagrams
• Final control elements, drives, controllers, and safety systems
• A graded workbook with answer keys to test your understanding

For instrumentation students and new technicians, this book is designed to take you from basic electrical concepts to reading real process drawings. If you are starting a career in process instrumentation or need a clear reference for the symbols and standards used in industrial facilities, this is your starting point.

A practical guide to numerical methods for engineers and scientists, teaching each technique in MATLAB, Excel, and VBA with chemical engineering applications.

Answer the question first, then find out what you actually knew.

That is how this book works. Each chapter puts exam-realistic structural problems in front of you, then explains the solution in full engineering detail: how the load combination was chosen, why the section is compact or slender, where the development length came from, what changed when the wall became slender. You cover gravity and lateral loads, analysis, reinforced and prestressed concrete, steel members and connections, wood, masonry, foundations, retaining structures and temporary works, then close with mixed timed sets that mimic exam pacing. Every rationale names the reference you should have opened on screen.

For civil engineers taking the structural depth exam and for structural engineers returning to licensure after a gap, this book builds the habit of answering before reading the explanation, so you learn what you truly know and where to focus next.

What you will learn:

• Navigate the structural depth exam format and question types with confidence.
• Apply gravity load combinations and load factors correctly for buildings and bridges.
• Determine lateral loads from wind and seismic provisions and distribute them through structural systems.
• Perform structural analysis for determinate and indeterminate structures, including approximate methods.
• Design reinforced concrete members for flexure, shear, and development, and handle slender walls.
• Analyze prestressed concrete members for service and strength limit states.
• Select and check structural steel members and connections, including bolted and welded details.
• Design wood and masonry elements according to code requirements.
• Evaluate foundations, earth retention systems, and temporary structures for constructability.

This book is for civil engineers preparing for the structural depth portion of the PE exam and for structural engineers returning to licensure after time away. If you want to test your knowledge under realistic conditions and learn from detailed, reference-backed explanations, this book is for you.

Most control texts bury the idea under transform algebra. This one tells you what each plot means before it derives anything.

Control Systems Theory and Analysis is a working outline of feedback control, digital signal processing and analog circuit analysis, written for readers who want to understand what a control system is doing before they wrestle with the mathematics behind it. The book opens with the circuit analysis and op-amp building blocks you need to model real hardware, then builds transfer functions and reads time-domain responses in terms of damping, overshoot and settling time. Stability is introduced through Routh-Hurwitz and pole locations, steady-state error through system type, and design through root locus, Bode plots, gain and phase margin and the Nyquist criterion.

From there the book moves into practical compensation: lead, lag and PID tuning, with windup and derivative-filtering fixes that matter when a controller meets a real plant. The later chapters extend the same ideas into state-space pole placement, observers, sampling, the z-transform and digital filtering. A single motor loop runs through every method, so you can compare designs honestly instead of learning each technique in isolation.

What you will learn:

• Circuit analysis and analog building blocks, including op-amp configurations used to model real hardware
• Laplace transforms, transfer functions and the modelling of physical systems
• Time-domain response: damping, overshoot, rise time and settling time
• Stability by Routh-Hurwitz and pole location, and steady-state error by system type
• Root locus, frequency response, Bode plots, gain and phase margin, and the Nyquist criterion
• Lead, lag and PID compensation, including windup and derivative-filtering fixes
• State-space methods: pole placement and observer design
• Sampling, the z-transform and digital control loops
• Digital signal processing techniques applied to control systems

Written for electrical and mechanical engineering students and for self-taught engineers who want a clear, method-by-method outline they can return to while studying or designing, this book keeps the focus on what each tool tells you about a system and when to reach for it.

High-hazard facilities rarely fail for want of a rule. They fail where the rule was written for a plant that no longer exists, or where the procedure was accurate but nobody used it as written.

This book addresses both halves of that failure. On the engineering side, it covers hazard analysis and layer of protection work, inherently safer design, layout and separation, materials and corrosion allowance, relief and effluent design, area classification, fire and gas detection, and safety instrumented function integrity. On the operating side, it covers procedure development from task analysis, conduct of operations with handover and field verification, management of change, risk-based inspection and deficiency handling, contractor oversight and permit systems, and investigation with metrics that actually lead.

Written for operating companies and contractors in high-hazard service, the book connects engineering design guidelines to the operational discipline that keeps them valid over time. It treats process safety as an integrated system, not a collection of documents. Each chapter provides practical guidance that can be applied directly to existing facilities, new projects, and contractor scopes of work.

What you will learn:

• How to build and sustain a risk-based process safety programme that fits your organisation
• Methods for process hazard analysis and layer of protection analysis that produce usable results
• How to apply inherently safer design principles and plant layout to reduce risk at the source
• Materials selection, corrosion allowance, and design for mechanical integrity
• Pressure relief and effluent handling design that accounts for real operating scenarios
• Electrical area classification, ignition control, and fire and gas detection system design
• Safety instrumented system integrity, including function testing and proof test intervals
• Procedure development from task analysis, plus conduct of operations and operational discipline
• Management of change, risk-based inspection, contractor control, permit systems, and incident investigation with leading metrics

Who it is for: Process safety engineers, operations and maintenance managers, EHS professionals, and contractors working in oil and gas, chemicals, petrochemicals, and other high-hazard industries. It is also suitable for engineers moving into process safety roles and for teams responsible for closing the gap between written procedures and actual practice.

A practical guide to designing, deploying and operating production machine learning systems, from framing the prediction task through feature pipelines, serving, monitoring, retraining and MLOps orchestration.

Rungs are easy to copy and hard to trust. This book teaches you to write logic you can commission and hand over.

Most PLC knowledge is passed around as screenshots and tribal memory. This book replaces that with a structured path through Studio 5000, from controller selection and project organisation to the scan cycle, tag architecture, and machine safety. You will configure a controller, set a communication path, go online, and build a tag structure with user-defined types and aliases that still makes sense a year later. The emphasis throughout is on logic that can be read, tested, and maintained by someone other than its author.

You will write seal-in motor circuits with correct stop priority, apply on-delay, off-delay and retentive timers to conveyor and dwell problems, scale analog inputs from raw counts to engineering units, and tune a process loop without integral windup. Later chapters cover task structure and scan behaviour, industrial Ethernet, produced and consumed tags, drive control, reusable add-on instructions, safety controller logic for emergency stops, guard doors and light curtains, and operator screen, alarm and commissioning work. Each topic is tied to the practical decisions a controls engineer or maintenance technician makes on the plant floor.

What you will learn:

• Select and configure ControlLogix and CompactLogix hardware, then create a project and go online with a communication path
• Build tag structures with user-defined types and aliases that remain readable across the life of a machine
• Write bit instructions and seal-in motor control logic with correct stop priority and safe restart behaviour
• Apply timers and counters to conveyor, dwell, and sequencing problems, including retentive and off-delay cases
• Use compare, math, move, and array instructions to process data and handle recipes and part tracking
• Structure tasks, programs, and routines, and understand how scan behaviour affects logic execution
• Configure I/O and scale analog inputs from raw counts to engineering units
• Tune process loops and avoid integral windup in flow, pressure, and temperature control
• Implement industrial Ethernet, produced and consumed tags, and drive control between controllers
• Create reusable add-on instructions and structured text, and apply safety controller logic for emergency stops, guard doors, and light curtains
• Design HMI screens, alarms, and commissioning and troubleshooting workflows

Written for maintenance technicians, controls engineers, and automation students, this book assumes you want to move beyond copying rungs to writing logic you can defend. If you work with Rockwell Automation platforms and need a practical reference that connects programming decisions to commissioning and handover, this is for you.
