Power Line Communications: Principles, Standards and Applications

Power Line Communications: Principles, Standards and Applications 

Lutz Lampe, Andrea M. Tonello

Preference :

Power line communications (PLC) reuse existing infrastructures (i.e. power lines) whose
primary purpose is the delivery of AC (50 Hz or 60 Hz) or DC electric power, for the purpose
of data communications. Hence, compared to the electric power ‘signal’, PLC uses highfrequency
signals with frequency components starting from a few hundred Hz up to a few
hundred MHz. The plurality of frequency bands used for PLC is related to different applications
supported by PLC and their data-rate requirements, the specifics of grid topologies over which
PLC is applied, as well as the ability of PLC technology to deal with the harsh communication
environment. Before elaborating on this further, we first briefly review the terminology that
has been used to describe PLC.

This book is the second edition of Power Line Communications: Theory and Applications for
Narrowband and Broadband Communications over Power Lines published in 2010. As for
the first edition, it has been our intention to present the most comprehensive coverage of the
technical field of power line communications (PLC) that is available in a single publication. The
scope of this book is uniquely wide, not only for a book on PLC. Compared to the first edition,
the content has been updated and in part restructured. In particular, we have significantly
expanded the part dedicated to applications of PLC, which is attributed to the further maturity
of PLC technology in terms of consolidated specifications and standards and also reflected in
the modification of the subtitle for this edition. Furthermore, recent innovations and changes
related to channel characterization, transmission techniques and regulation are included in this
edition.

Maintenance Engineering Handbook Seventh Edition

Maintenance Engineering Handbook Seventh Edition

Keith Mobley, Lindley Higgins

Preference :

Some engineering fields change dramatically from year to year, with radical breakthroughs in
technology happening often. These fields may have hundreds or more papers and texts published
each year on the latest best practices. Maintenance engineering is a field which, for the most part,
hasn’t fundamentally changed much over the years. And there aren’t many sources for the latest
information or best practices.
But in recent years, maintenance engineering has, more and more, put an emphasis on true reliability.
A business which is asset-intensive, such as manufacturing, relies on a reliability-centered
field of engineering to be successful. In my opinion, reliability engineering itself has become a technology
used for the purpose of improving manufacturing capacity, without capital investment.
The Maintenance Engineering Handbook has long been regarded as the premier source for
expertise on maintenance theory and practices for any industry. This text has been considered
invaluable and now, this latest edition defines those practices that are critical to developing an
effective reliability engineering function within your business.
This text is no longer just about mechanical, electrical, and civil maintenance engineering.
Instead, the seventh edition also focuses on recognized and proven best practices in maintenance,
repair, and overhaul (MRO) inventory management, root-cause analysis, and performance management.
Keith Mobley, the editor in chief of this text, has more than 35 years of direct experience in
corporate management, process and equipment design, and reliability-centered maintenance
methodologies. For the past 16 years, he has helped hundreds of clients across the globe achieve
and sustain world-class performance through the implementation of maintenance and reliability
engineering principles.
You may spend your career worrying about excessive downtime and high maintenance costs as
a result of repetitive failures. As a fellow veteran maintenance and reliability engineer, I encourage
you to recognize that this field is changing and improvements are being made that empower today’s
business leaders. This text can help you reap the benefits of those changes so that your hard work
produces the best possible results.

Electrical Power Cable Engineering

Electrical Power Cable Engineering

Leonard L. Grigsby

Preference :

Electrical cable can be considered as just a conductor with an overlying insulation or an exterior shield or jacket. Perhaps with this naive, simplistic concept is part of the reason that cable engineering, especially for power cable, has been largely neglected in current electrical engineering education in the United States with its emphasis on computers, electronics, and communication. But power cable does electrically connect the world! The history, so interestingly presented
in Chapter 1 of this book, shows how the subject evolved with both great success and sometimes unexpected failure.
As this book emphasizes, cable engineering is technically very complex. Certainly electrical, mechanical, and even to some extent civil engineering are involved in interrelated ways. Many other disciplines-physics, inorganic chemistry, organic (primarily polymer) chemistry, physical chemistry, metallurgy, corrosion and with tests and standards in all of these areas-are concerns. Of course, it is impossible in one book to deal with all of these aspects in a completely comprehensive way. However, the various components of power cables are discusseded here with sufficient detail to provide an understanding of the basic considerations in each area. Reference to detailed sources provides a means for those with greater interest to pursue specific subjects.
The importance of factors involved in different types of cable installation is stressed. Long vertical cable runs have special problems. Installation in ducts may lead to problems with joints, terminations, elbows, and pulling stresses. At first, cable with extruded insulation was buried directly in trenches without recognition of the then unknown problem of “water treeing” in polyethylene, which was originally thought to be unaffected by moisture. After massive field failures, well over a thousand papers have been written on water treeing! Field failures can involve many factors, e.g., lightning, switching surges, repeated mechanical stressing, and swelling of voltage grading shields in contact with organic solvents such as oil and gasoline. It is important to recognize how such diverse factors can affect the performance of cable in the field.

How to Repair Briggs and Stratton Engines

How to Repair Briggs and Stratton Engines

 Paul Dempsey

Preference :

Briggs & Stratton is the world’s largest producer of small engines with an annual output of 10.5 million units or 30,000 a day. More than 60% of small engines sold worldwide and half of the portable generators carry the blackand-white Briggs logo. Like Harley-Davidson, also based in Milwaukee, Briggs and Stratton is an American icon. One reason why Briggs & Stratton enjoys an almost mythic stature among Americans of a certain age is the belief that its products do not change. Wars and presidents come and go, but the Briggs side-valve lives forever. And when the mower won’t start, you can repair it without a degree in engineering. The skills learned in our youth still have relevance and can be passed on to our grandchildren, that is, if they are open to a world larger
and more real than computer games.
Actually, Briggs engines—even the old side-valve with its rectangular cylinder head and quaint rewind starter—have undergone more-or-less continuous change. And more changes are coming to the products and to the way the company does business.
But, withal, there is a kind of elegant simplicity to Briggs engineering. A case in point is the Easy-Spin compression release that automatically raises the intake valve without adding as single part to the engine. Another example is the nylon Pulsa-Jet carburetor with its built-in fuel pump and an almost zero requirement for machine work. Briggs was the first maker of utility engines to offer overhead valves, the first to build vertical-crankshaft aluminum blocks, and the first to use aluminum cylinder bores. To encourage proper maintenance, spark plugs, air filters and oil-drain plugs are readily accessible. Head bolts can be reached by removing the shroud, an operation that can be accomplished in five minutes or less.

Cost Estimation of Structures in Commercial Buildings

Cost Estimation of Structures in Commercial Buildings

Surinder Singh

Preference :

Approximate cost estimates for structural works are always needed for one reason or another at the initial design stage in the building construction industry, and the techniques generally used for their preparation are the percentage estimate method, the superficial or floor area method (also known as the square metre method) and the approximate quantities method.
A proper application of the first two methods requires an in-depth knowledge of historical cost information of completed buildings and of the effect of design parameters on the construction cost.
Information on constituent quantities of completed buildings is not readily available. Realistic estimates may thus require the engineer to work out different schemes so that the most economical one may be selected. It is time-consuming and unsystematic if this has to be done for every project. With these drawbacks in mind, the author has supplied the basic data and discussed, in relation to commercial buildings ranging from 5 to 50 storeys, the effect of different design parameters on quantities of constituents for common structural systems, namely the reinforced concrete beam and slab system, the flat slab and waffle slab systems, and the prestressed concrete beam and reinforced concrete slab system. This approach to constituent quantities will enable both students and professionals to develop estimates with ease, speed and accuracy.

A critical review of the previous work relating to structural design economics has indicated that the
investigations were either based on records of past completed projects or on first principles by analysis, design and computation of quantities. The former approach has a number of drawbacks and, in view of this, the author decided to follow the more scientific approach of analysis, design and computation of quantities for structures of varying heights and structural systems based on the latest British Standards and Codes.
The information on constituent quantities is presented in the form of charts and the effects of design
parameters such as column grid size, number of storeys, location of structural components, arrangement of beams, grades of concrete, etc. on the quantities of various constituents of concrete construction for different structural systems have been discussed. Using the charts presented, applications for comparative cost estimation to assess the effect of various design parameters, for approximate structural cost estimation of an overall project given its design features, for checking the estimates for structural works, for calculation of quantity index for structural works, and for various other building economics studies have been illustrated.

Communications Industrial Networking and TCP IP Book

Communications Industrial Networking and TCP IP Book

IDC Technologies

Preference :

A LAN is a communications path between one or more computers, file-servers, terminals, workstations and various other intelligent peripheral equipment. A LAN allows access to devices to be shared by several users, with full connectivity between all stations on the network.
The connection of a device into a LAN is made through a node. A node is any point where a device is connected and each node is allocated a unique address number. Every message sent on the LAN must be prefixed with the unique address of the destination node. LANs operate at relatively high speed (i.e. 2 - 100 Mbps range and upwards) with a shared transmission medium over a fairly small local area.
In a LAN, the software that controls the transfer of messages among the devices on the network must deal with the problems of sharing the common resources of the network without conflict or corruption of data. Since many users can access the network at the same time, some rules must be established on which devices can access the network, when and under what conditions. These rules are covered under the general subject of access control. The rules that apply depend on the structure and type of the network, e.g. a star, ring or bus topology and a token passing or CSMA/CD network type.

Handbook of Industrial Engineering Equations, Formulas, and Calculations

Handbook of Industrial Engineering Equations, Formulas, and Calculations

Adedeji B. Badiru, Olufemi A. Omitaomu

Preference :

Calculations form the basis for engineering practice. Engineering researchers, instructors, students, and practitioners all need simple guides for engineering calculations. Although several books are available in the market for general engineering calculations, none is available directly for industrial engineering calculations. This book is designed to fill that void. It presents a general collection of mathematical equations that are likely to be encountered in the practice of industrial engineering.
Industrial engineering practitioners do not have to be computational experts; they just have to know where to get the computational resources that they need. This book provides access to computational resources needed by industrial engineers. Industrial engineering is one of the most versatile and flexible branches of engineering. It has been said that engineers make things, whereas industrial engineers make things better. To make something better requires an understanding of its basic characteristics. The underlying equations and calculations facilitate that understanding. This book
consists of several sections, each with a focus on a particular problem area. The book
include the following topics:


  • Basic math calculations
  • Engineering math calculations
  • Production engineering calculations
  • Engineering economics calculations
  • Ergonomics calculations
  • Facility layout calculations
  • Production sequencing and scheduling calculations
  • Systems engineering calculations
  • Data engineering calculations
  • Project engineering calculations
  • Simulation and statistical equations

The book is unique in the market because it is the first book of its kind to focus exclusively on industrial engineering calculations with a correlation to applications for practice.

HVAC Engineers Handbook

HVAC Engineers Handbook

F. Porges

Preference :

This book contains in a readily available form the data, charts and tables which are regularly
required by heating, ventilating and air conditioning engineers in their daily work.
The data is presented in a concise manner to enable it to be applied directly in the actual
daffy work of the HVAC engineer. The book is designed for everyday use and a comprehensive
bibliography has been included for the benefit of those who wish to pursue the theoretical
side of any particular topic.
For this edition some errors have been corrected, the explanatory notes on the psychr~
metric chart have been improved and the chart in previous editions has been replaced, with
permission, by the well known CIBSE chart. Additional data has been included on design
temperatures and ventilation rates and information has been inserted on precautions against
legionellosis in both hot water systems and air conditioning plant. The data on duct thicknesses
and sizes has been revised to conform to current practice. A new section has been
included on natural ventilation and the information on types of refrigeration compressors
has been expanded. The data on refrigerants has been completely revised to list the new
non4~FC and non-HCFC refrigerants. Practising engineers will still meet old plant which contains
refrigerants which are now obsolete or obsolescent, and therefore the properties of the
more important of these are also given.
The policy of previous editions of giving tabulated data in both SI and Imperial units has
been continued although theoretical expressions are generally given only in SI units.

Operation and Control in Power Systems

Operation and Control in Power Systems

S. R. Murty Book

Preference :

Power system engineering is a branch where practically all the results of modern control
theory can be applied. Such an application will result in economy, better quality of service and
the least inconvenience under abnormal situations, both anticipated and unforeseen.
Control system design, in general, for its analytical treatment, requires the determination
of a mathematical model from which the control strategy can be derived. While much of the
control theory postulates that a model of the system is available. It is also necessary to have a
suitable technique to determine the models for the process to be controlled. Thus, it is
required to model and identify power system components using both physical relationships
and experimental or normal operating data. The objective of system identification is the
determination of a mathematical model characterizing the operation of a system in some form.
The available information is either system outputs or some functions of outputs which may
contain measurement noise. The inputs may be known functions applied for the purpose of
identification, or unknown functions which it may be possible to monitor somehow, or a
combination of both.
The identified model may be in the form of differential equations, difference equations,
transfer functions, etc.
Even though all systems are nonlinear to some extent, the assumption of a linear model
leads to simpler models which can yield meaningful results with fairly good accuracy. A
system may be classified as stationary or non stationary. During the period of operation, when controls are implemented, the system is normally assumed to be stationary. The system equations
may be formulated either in the continuous mode or in the discrete mode. While measurements
and predicted values are available at discrete intervals, continuous representation is the most
familiar mode. Transformation from continuous to discrete formulation is a straight forward
process.

Earthquake Resistant Design of Structures, Second Edition

Earthquake Resistant Design of Structures, Second Edition

Duggal, S. K

Preference :

This book introduces and explains all aspects of earthquake-resistant design of structures. Designed as a textbook for undergraduate and graduate students of civil engineering, practising engineers and architects will also find the book equally useful. It has been assumed that the reader is well acquainted with structural analysis, structural dynamics, and structural design.
The design of earthquake-resistant structures is an art as well as science. It is necessary to have an understanding of the manner in which a structure absorbs the energy transmitted to it during an earthquake. The book provides a comprehensive coverage of the basic principles of earthquake-resistant design with special emphasis on the design of masonry, reinforced concrete, and steel buildings. The text is focussed on the design of structural and non-structural elements in
accordance with the BIS codes.
This book contains 11 chapters, which comprehensively discusses the design of earthquake-resistant structures. Starting with the elements of earthquake theory and seismic design, dynamics of structures and soils and their seismic response, the book goes on to elucidate the conceptualization and actualization of the design of earthquake-resistant structures. Detailed seismic analyses of different types of buildings, such as masonry, timber, reinforced concrete, and steel buildings, follow. Finally, a comprehensive discussion of the behaviour of non-structural elements under seismic forces and an analysis of the 2001 Bhuj earthquake are presented as concluding chapters.

Outboard Engines Maintenance Troubleshooting and Repair

Outboard Engines Maintenance Troubleshooting and Repair

Ed. Sherman

Preference :

Before you can fix a sick engine, you have to know what makes a healthy engine run. The principle is
pretty simple: A piston fits into each cylinder. When fuel explodes on top of the piston, the piston is forced to move in the only direction it can, down the cylinder. The piston, which is connected by a rod to a crankshaft, turns this downward motion into something more useful by rotating the crankshaft. The crankshaft, in turn, shoves the piston back up the cylinder for more
action. Your Engine’s Four Basic Needs All outboard engines must:
• Admit a mixture of fuel and air.
• Compress that mixture.
• Ignite the compressed mixture.
• Clear away the burned gases.

Remember those four needs: fuel, compression, ignition, and exhaust. They’ll come in handy when
you’re troubleshooting. And they’re valid for all kinds of internal combustion engines, two-strokes, and fourstrokes; gasoline engines and diesels. Two-stroke engines complete the full cycle of fuel
induction, compression, ignition, and exhaust with just two strokes of the piston in the cylinder, one up and one down. In four-stroke engines, the piston must travel up twice and down twice—four strokes in all—to complete the same cycle. The pay-off is that four-strokes are more efficient than two-strokes. Later, we’ll discuss in more depth the relative advantages of twostroke and four-stroke engines. Right now, what you need to know is that two-strokes are more powerful for their weight, so you get a lot of horsepower from a light engine. They’re also mechanically simpler.
But they are gas guzzlers and don’t particularly like slow running. Their greatest sin is that they burn their lubricating oil along with the gasoline. This causes so much exhaust pollution that the U.S. Environmental Protection Agency (EPA) is forcing two-stroke outboard-engine manufacturers to reduce hydrocarbon emissions by 75 percent within the next 10 years. (You’ll find more information about that in Chapter 11.)
Four-stroke engines are heavier, and usually costlier because they need fuel-intake valves and exhaust valves. But they’re more economical to run than two-strokes—they get far better mileage. Significantly, they’re also much kinder to the environment. They don’t burn their lubricating oil, so they pollute much less.

Communication Protocol Engineering

Communication Protocol Engineering

Miroslav Popovic 

Preference :

Originally, the term protocol was related to the customs and regulations dealing with diplomatic formality, precedence, and etiquette. A protocol is actually the original draft, minutes, or record from which a document, especially a treaty, is prepared, e.g., an agreement between states. Today, in the
context of computer networks, the term protocol is interpreted as a set of rules governing the format of messages that are exchanged between computers. Sometimes, especially if we want to be more specific, we use the term communication protocol instead.
The title of this book, Communication Protocol Engineering , is used to emphasize the process of developing communication protocols. Like other engineering disciplines, communication protocol engineering typically
• Requirements and analysis
• Design
• Implementation
• Test and verification
The process as described in this book is ideally the union of the UML (Unified Modeling Language)-driven unified development process (Booch et al., 1998), Cleanroom engineering (formal system design verification and statistical usage testing), and some elements of Agile programming (particularly unit testing based on JUnit). Of course, each organization should adapt and tune the process to its own needs and goals. For example, one organization may stick to the UML-driven unified development process, another may prefer Cleanroom engineering, yet another may use the combination of both, and so forth.

Handbook of Electrical Design Details 2nd Edition

Handbook of Electrical Design Details 2nd Edition

Sclater, Traister

Preference :

This is the second edition of the Handbook of Electrical Design Details (HEDD), originally published in 1997. It is a well-illustrated reference book on electrical power and lighting—how it is generated, transmitted, distributed, and used. Considerable new information has been added in this edition but it is a smaller volume, making it more user-friendly and easier to keep on a desk or shelf. Among the topics new to this edition are computer-aided electrical drawing (CAD), basic switch and receptacle circuit wiring, outdoor low-voltage wiring, telephone and structured wiring, and electrical surge protection. This book begins with a discussion of electrical drawing and symbols and the importance of specifications in electrical projects. The chapters that follow cover power generation, transmission, and distribution. Design details of generators and transformers and their role in delivering electric power to consumers’ homes or buildings are included. Aerial and buried service entrances are explained and illustrated, as are main panels or load centers and the principles of earth grounding. Properties of wire and cable are presented, and the dimensions and the details of basic electrical wiring devices are described and illustrated. The rules for installing branch circuit wiring are given along with an example of a load calculation and the reasons for load balancing. Extensive coverage is given to lighting, lamps, and indoor and outdoor lighting design. Other chapters explain telephone and structured wiring, electric motors, emergency and standby electrical systems, and the essentials of surge protection. This edition of HEDD makes many references to the National Electrical Code® (NEC®)* on all topics governed by the code, such as wiring protection, wiring methods and materials, and standard equipment, where appropriate for reader guidance. In the chapters on wire, cable, and wiring devices, individual drawings represent whole classes of standard products such as switches, receptacles, and lamps, replacing the many repetitive catalog pages that appeared in the first edition. Each chapter begins with a content summary called “Contents at a Glance” and an Overview of the chapter. In addition, there are separate glossaries of technical terms at the ends of the chapters on transformers, electrical service entrance, wiring, lighting, motors, telecommunications, emergency and standby systems, and surge protection, for handy reference and quick memory refreshing. This second edition of HEDD has been written in an informal descriptive style, with minimal use of mathematics. The readers most likely to benefit from this book are electrical contractors, electricians, and instructors. Others who will find this volume helpful are those employed in the electrical industry in manufacturing, service.
