## Structural Stability of Steel: Concepts and Applications for Structural Engineers

Theodore V. Galambos

Preference :

In order to truly understand the behavior and design of metal structures, an engineer needs to have a fundamental understanding of structural stability. More so than structures designed using other construction materials, steel structures are governed to a great extent on stability limit states. All major international design specifications include provisions based on stability theory. The purpose of this book is to provide students and practicing engineers with both the theory governing the stability of steel structures and a practical look at how that theory translates into design methodologies currently implemented in steel design specifications. The topics presented in the text pertain to various aspects of elastic buckling and inelastic instability. An understanding of stability limits is very important in the design of structures: Catastrophic failures can, and tragically have resulted from violating fundamental principles of stability in design. Maintaining stability is particularly important during the erection phase of construction, when the structural skeleton is exposed prior to the installation of the final stabilizing features, such as slabs, walls, and/or cladding.

## Bridge Engineering: Rehabilitation, and Maintenance of Modern Highway Bridges

Demetrios Tonias

Preference :

Highway bridges dot our landscape by the hundreds of thousands. We pass over and under them, paying no more attention to these structures than we would a tree or a hill. Indeed, the highway bridge has become part of our environment. From a historical perspective, the modern highway bridge was born in the depression years of the 1930s, came of age in the 1950s to 1970s, and it is entering its golden years in the 1980s and 1990s. These structures have performed so well, and they have been so durable, that most of us, engineers or not, tend to take the highway bridge for granted. We simply cannot envision a time when the life of these structures will reach the stage when they will no longer be so durable; when we will no longer be able to take the highway bridge for granted. We have, however, reached that time.

## Mark's Calculations For Machine Design

Thomas H. Brown

Preference :

As the title of this book implies, Marks’ Calculations for Machine Design was written to be a companion to Marks’ Standard Handbook for Mechanical Engineers, providing detailed calculations to the important problems in machine design. For each of the over 175 examples presented, complete solutions are provided, including appropriate figures and diagrams, all algebra and arithmetic steps, and using both the U.S. Customary and SI/Metric systems of units. It is hoped that Marks’ Calculations for Machine Design will provide an enthusiastic beginning for those just starting out in mechanical engineering, as well as provide a comprehensive resource for those currently involved in machine design projects. Marks’ Calculations for Machine Design is divided into two main parts: Part 1, Strength of Machines, and Part 2, Application to Machines. Part 1 contains seven chapters on the foundational principles and equations of machine design, from basic to advanced, while Part 2 contains three chapters on the most common machine elements based on these principles and equations.

## Principles of Testing Soils, Rocks and Concrete

T.S. NAGARAJ

Preference :

In civil engineering, a wide spectrum of materials, natural as well as processed, are adopted for usage. However, a significant involvement is with soils, rocks, and concrete. While rocks and soils are materials of geological origin, concrete is a processed material using these geological materials as ingredients at different stages. The inherent nature and diversity of geological processes involved in the formation of rocks and soils lead to wide variability in their in-situ state. Hence, the geotechnical engineer usually has to adjust his designs to accommodate the prevailing properties of in-situ soils and/or resort to appropriate ground engineering methods. On the other hand, concrete has become an indispensable construction material that most obligingly conforms to new concepts in design with the possibility of realizing the same through advanced construction technology.

## Basic Civil Engineering

Satheesh Gopi

Preference :

The aim of compiling this book has been to give a working knowledge of the important details of civil construction, materials used in civil engineering, including the source of raw materials, their characteristics, the process of manufacture, their defects, structure, and uses in the industry, and the basics of surveying and leveling and several other major topics in civil engineering to all engineering students in a systematic way.

# Solved Example on Design And Detailing Of Counterfort Retaining Wall

When the height of the retaining wall exceeds about 6 m, the thickness of the stem and
heel slab works out to be sufficiently large and the design becomes uneconomical. In
such a case counterforts having trapezoidal section fixed at the base slab are provided
at intervals of 1.5 m to 3 m. The counterforts support the heel slab and the vertical stem.
The design principles for different components of the wall are discussed below.

## Power Line Communications: Theory and Applications for Narrowband and Broadband Communications over Power Lines

Hendrik C. Ferreira

Preference :

With this book, we took on the challenge to cover most of the technical field of Power Line Communications (PLC) with wide-ranging contributions on selected topics. The scope of this book is thus uniquely wide, not only for a book on PLC but also to our knowledge for any book in the general field of Telecommunications. The inspiration for this wide coverage came from a survey of the many papers that contributed to the International Symposium on Power Line Communications from 1997. The reader will thus find information widely dispersed in the literature, including research publications, standards documentation, and even trade literature. We have attempted coverage of both techniques and information on which there is currently consensus, as well as a limited selection of promising ones still under investigation. The goal of this book is thus to inform newcomers to the exciting field of PLC, to inspire further research, and perhaps to contribute to future consensus. This book may also pave the way for future books focusing more deeply on perhaps just one individual subfield of the various subfields covered here.

Content :
• Introduction
• Channel Characterization
• Electromagnetic Compatibility
• Coupling
• Digital Transmission Techniques
• Protocols for PLC Systems.
• Industrial and International Standards on PLC-based Networking Technologies
• Systems and Implementations

## Engineering Materials 1: An Introduction to Properties, Applications, and Design

D R H Jones

Preference :

Innovation in engineering often means the clever use of a new material—new to a particular application, but not necessarily (although sometimes) new in the sense of recently developed. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials. When the plastic teaspoon buckles as you stir your tea, and when a fleet of aircraft is grounded because cracks have appeared in the tailplane, it is because the engineer who designed them used the wrong materials or did not understand the properties of those used. So it is vital that the professional engineer should know how to select materials which best fit the demands of the design—economic and aesthetic demands, as well as demands of strength and durability. The designer must understand the properties of materials, and their limitations.

## Principles and Practice of Ground Improvement

Jie Han

Preference :

Ground improvement is popular in many countries to solve difficult geotechnical problems, especially when construction necessarily occurs in problematic soils and under difficult geotechnical conditions. Many recent developments in equipment, materials, and design methods have made ground improvement technologies more effective, efficient, and economic. However, the state of practice for most ground improvement technologies is that the practice is ahead of theory. Some contractors have developed their proprietary technologies, design methods, and construction techniques for their competitive advantages. Most of the existing books on ground improvement are focused on the concept, application, and case study. However, few books have been devoted to the principles and design methods of ground improvement. This book covers both theoretical and practical aspects in the design and construction of a variety of ground improvement technologies commonly used in practice.

## Electricity and Magnetism

EDWARD M. PURCELL

Preference :

The existence of this book is owed (both figuratively and literally) to the fact that the building blocks of matter possess a quality called charge. Two important aspects of charge are conservation and quantization. The electric force between two charges is given by Coulomb’s law. Like the gravitational force, the electric force falls off like 1/r2. It is conservative, so we can talk about the potential energy of a system of charges (the work done in assembling them). A very useful concept is the electric field, which is defined as the force per unit charge. Every point in space has a unique electric field associated with it. We can define the flux of the electric field through a given surface. This leads us to Gauss’s law, which is an alternative way of stating Coulomb’s law. In cases involving sufficient symmetry, it is much quicker to calculate the electric field via Gauss’s law than via Coulomb’s law and direct integration. Finally, we discuss the energy density in the electric field, which provides another way of calculating the potential energy of a system.

## Machine Elements in Mechanical Design

Robert L. Mott

Preference :

The objective of this book is to provide the concepts, procedures, data, and decision analysis techniques necessary to design machine elements commonly found in mechanical devices and systems. Students completing a course of study using this book should be able to execute original designs for machine elements and integrate the elements into a system composed of several elements. This process requires a consideration of the performance requirements of an individual element and of the interfaces between elements as they work together to form a system. For example, a gear must be designed to transmit power at a given speed. The design must specify the number of teeth, pitch, tooth form, face width, pitch diameter, material, and method of heat treatment. But the gear design also affects, and is affected by, the mating gear, the shaft carrying the gear, and the environment in which it is to operate. Furthermore, the shaft must be supported by bearings, which must be contained in a housing. Thus, the designer should keep the complete system in mind while designing each individual element. This book will help the student approach design problems in this way.

## Project Management, 12th Edition

H a r o l d K e r z n e r

Preference :

Project management has evolved from a management philosophy restricted to a few functional areas and regarded as something nice to have to an enterprise project management system affecting every functional unit of the company. Simply stated, project management has evolved into a business process rather than merely a project management process. More and more companies are now regarding project management as being mandatory for the survival of the firm. Organizations that were opponents of project management are now advocates. Management educators of the past, who preached that project management could not work and would be just another fad, are now staunch supporters. Project management is here to stay. Colleges and universities are now offering undergraduate and graduate degrees in project management.

## Problem Solving in Quantum Mechanics

Marc Cathay

Preference :

Over the last two decades, there has been a dramatic increase in the study of physical and biological systems at the nanoscale.

## Building a Project Work Breakdown Structure

DENNIS P. MILLER

Preference :

The origin and exact date of development of the WBS (Work Breakdown Structure) are not exactly clear. It appears that it was developed in response to some unstated problem within the United States Department of Defense (DoD). Most authors (writing on this subject) and their articles do not address the source of the WBS. It was not until 2002 that a booklet clarified what had been, until that time, simply “folklore.” Haugan’s booklet clarified a number of misconceptions that had developed during the previous 45 years. This booklet is an excellent reference for exact details. However, we now know that the WBS was developed as a component of a larger effort to control DoD projects from the early 1960s through to today. The official reference (as of 2002) was the DoD’s site for the WBS. The exact World Wide Web reference has changed and, at this writing, is lost. A recent search for “Work Breakdown Structure” on the World Wide Web (WWW) produced more than 2,260,000 sites. This is an expression of both the commercialism of the WWW and the popularity of the WBS.

## Introduction to Artificial Intelligence

Philip C. Jackson

Preference :

Are we intelligent enough to understand intelligence? One approach to answering this question is "artificial intelligence," the field of computer science that studies how machines can be made to act intelligently. This book is intended to be a general introduction to artificial intelligence (AI). The subjects for discussion are machines that can solve problems, play games, recognize patterns, prove mathematical theorems, understand English, and even demonstrate learning by changing their own behavior to perform such tasks more successfully. In general, this book is addressed to all persons who are interested in studying the nature of thought, and hopefully, much of it can be read without previous formal exposure to computers.

## Principles of Transistor Circuits

S. W. Amos

Preference :

This ninth edition was introduced to bring the material up-to-date and to render all of the diagrams to the same standard. Some of the information from previous editions has been left out; either because it was obsolete or because it is not relevant to modern electronics. Most students are taught discrete component circuit analysis and design with silicon NPN transistors as the main active devices. Although the flexibility of approach is important (i.e. to be able to use both NPN and PNP devices of any semiconductor type), the redrawn diagrams have been changed to conform to the NPN silicon arrangement so that the learning process does not involve unfamiliar configurations. Some of the abbreviations have been modernized, and the gate turns off thyristor introduced along with optically coupled devices. Much of the section on digital techniques has been reworked to reflect current practice.

Content :
• 1 Semiconductor and junction diodes
• 2 Basic principles of transistors
• 3 Common-base and common-gate amplifiers
