Principles and Practice of Ground Improvement

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.

Water Treatment: Principles and Design

Water Treatment: Principles and Design 

John C. Crittenden

Preference :

This book is written to serve several purposes: (1) an undergraduate textbook appropriate for elective classes in water treatment, (2) a graduate-level textbook appropriate for teaching water treatment, groundwater remediation, and physical-chemical treatment, and (3) a reference book for engineers who are designing or operating water treatment plants. To convey ideas and concepts more clearly, the book contains the following important elements: (1) 170 example problems worked out in detail with units, (2) 399 homework problems, designed to develop students understanding of the subject matter, (3) 232 tables that contain physical properties of chemicals, design data, and thermodynamic properties of chemicals, to name a few, and (4) 467 illustrations and photographs. Metric SI and U.S. customary units are given throughout the book. Instructors will find the example problems, illustrations, and photographs useful in introducing students to fundamental concepts and practical design issues. In addition, an instructor’s solutions manual is available from the publisher.

Electricity and Magnetism

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

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.

Content :

• 1 The Nature of Mechanical Design
• 2 Materials in Mechanical Design
• 3 Stress and Deformation Analysis
• 4 Combined Stresses and Stress Transformation
• 5 Design for Different Types of Loading
• 6 Columns
• 7 Belt Drives, Chain Drives, and Wire Rope
• 8 Kinematics of Gears
• 9 Spur Gear Design
• 10 Helical Gears, Bevel Gears, and Wormgearing
• 11 Keys, Couplings, and Seals
• 12 Shaft Design
• 13 Tolerances and Fits
• 14 Rolling Contact Bearings

Project Management: A Systems Approach to Planning, Scheduling, and Controlling , 12th Edition

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.

Content :

• Overview
• Project Management Growth: Concepts and Definitions
• Organizational Structures
• Organizing and Staffing the Project Office and Team
• Management Functions
• Comm unications Management
• Conflicts

Structural Steel Design 3rd Edition

Structural Steel Design 3rd Edition 

Jason Vigil

Preference :

The knowledge and expertise required for the design of steel-framed structures is essential to architectural, civil and structural engineers, as well as to students intending to pursue careers in the field of structural design and construction. This textbook provides the fundamentals of structural steel design from a structural systems framework that involves not only the isolated design of the individual structural steel elements, but the design of these elements within the context of the entire structural system. This enables the reader to see the connection between each structural element and how and where they fit within the entire structural system, in addition to engendering a big picture view of structural steel design.

Content :

• Introduction to Steel Structures
• Design Methods, Load Combinations, and Gravity Loads and Load Paths
• Lateral Loads and Lateral Force Resisting Systems
• Tension Members
