Preference :

It is important to consider the fundamental definition of trend, which for this book is defined as the general direction in which something tends to move. The trends referenced or presented in this book should not be taken literally but rather considered as a general indication of both the direction and the magnitude of the subject matter. The intended audience for this document includes

• planners and managers of datacom facilities,
• facility design teams planning and designing datacom facilities, and
• facility architects and engineers who require insight on datacom equipment energy density and installation planning trends.

The variety of backgrounds and educational and practical experience among the intended audience can result in many different methods used to apply the information in this book. Fortunately, the book is designed for these multiple methods with the understanding that any methodology employed focuses on the concept of growth patterns.
Some practical examples of ways the growth patterns can be extracted are provided in this book, but there are additional methods that can be considered in the planning, design, and operation of a datacom facility.

Construction Inspection Manual 8th Edition

Construction Inspection Manual 8th Edition

William D. Mahoney

Preference :

Today, more than ever, construction requires a team effort. The escalation of costs, the need for faster scheduling and changes in the industry require full cooperation and understanding among all the parties. Successful production of the work under the traditional process requires the utmost order and efficiency to obtain the highest potential benefits. This goal can be reached only through the understanding that all parties have a mutual function and obligation to perform. Successful construction requires continuous checking, coordination, foresight, good judgment and overlapping
efforts by informed and qualified parties. The following parts reflect the Editorial Committee’s recommendations concerning the duties and responsibilities of the construction inspector, design
professional (architect/engineer), contractor/subcontractor, owner, lawyer, manufacturer’s representative and special consultants.

By definition, a contract is a legally enforceable agreement that sets forth the obligations of each party to the other. Any violation of these obligations (breach) can expose the party committing the breach to sanctions of law. The significant benefit of having an agreement is that a mutual understanding is developed by communicating expectations through clear definition of scope
and general/terms and conditions. Contracts come in many shapes and sizes. The most recognized standard document is the Standard Form of Agreement Between Owner and Architect –
AIA B141; however, many public owners, major private enterprises and design firms use their own “custom contracts”. In order to provide contracts that equitably serve the interest of both parties and meet the specific concerns of the project, amendments to both standard AIA and custom agreements are negotiated. It is of the utmost importance that the project inspector thoroughly review the agreements and the family of documents that define duties and responsibilities among the construction team composed of the owner, contractor and architect. The AIA A201/General Conditions of the Contract for Construction is the part of this family of contract documents that
establishes the ground rules for this construction team, where contractual relationships exist between the owner and the contractor and the owner and the architect but not between the contractor and the architect. Additionally, the supplementary conditions are prepared to modify the provisions of the general conditions in order to meet the particular requirements of the project by changing, adding to or deleting this document. The general conditions can also be drafted as “custom general conditions” by many public owners and major private enterprises.

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.



Content :
  • Preface
  • Channel Characterization
  • Electromagnetic Compatibility
  • Coupling
  • Digital Transmission Techniques
  • Medium Access Control and Layers Above in PLC
  • PLC for Home and Industry Automation
  • Multimedia PLC Systems
  • PLC for Smart Grid
  • PLC for Vehicles
  • Conclusions

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.
