Title: Structural Analysis of Geodesic Domes
Author: Marek Kubic, Supervised by: Charles Augarde
Publication: April 29, 2009, Durham University School of Engineering
File: PDF 3.6MB, 68 Pages
Description:
Taken from Abstract: A project to house 40 families in the Maharashtra region of India which began in January 2005 was halted shortly after it commenced due to concerns over the loading applied to a series of geodesic domes which form a large portion of the whole complex. Vigyan Ashram, the organisation that manufactures the domes, issued a request for the development of an affordable computer program that would allow them to model the structural response of the domes. The ensuing research into the design of the geodesic domes and the development of a spreadsheet based finite element package are the subject of this dissertation.
Structural Analysis of Geodesic Domes was written by Marek Kubik, under supervisory of Charles Augarde.

Piping and Pipeline Calculations Manual: Construction, Design Fabrication and Examination
Piping and Pipeline Calculations Manual: Construction, Design Fabrication and Examination
Butterworth-Heinemann | ISBN:1856176932 | 2010-02-19 | PDF | 375 pages | rar 10.8 MB | pdf 9.2 MB
The integrity of a piping system depends on the considerations and principles used in design, construction, and maintenance of the system. Piping systems are made of many components such as pipes, flanges, supports, gaskets, bolts, valves, strainers, flexibles, and expansion joints. These components can be made in a variety of materials, in different types and sizes, and may be manufactured to common national standards or according a manufacturers proprietary item. This book provides engineers and designers with a quick reference guide to the calculations, codes, and standards.The lack of commentary, or historical perspective, regarding the codes and standards requirements for piping design and construction is an obstacle to the designer, manufacturer, fabricator, supplier, erector, examiner, inspector, and owner who want to provide a safe and economical piping system. An intensive manual, this book will utilize hundreds of calculation and examples based on of 40 years of personal experiences of the author as both an engineer and instructor. Each example demonstrates how the code and standard has been correctly and incorrectly applied.

These components can be made in a variety of materials, in different types and sizes, and may be manufactured to common national standards or according a manufacturers proprietary item. This book provides engineers and designers with a ?quick reference guide? to the calculations, codes, and standards.
The lack of commentary, or historical perspective, regarding the codes and standards requirements for piping design and construction is an obstacle to the designer, manufacturer, fabricator, supplier, erector, examiner, inspector, and owner who want to provide a safe and economical piping system. An intensive manual, this book will utilize hundreds of calculation and examples based on of 40 years of personal experiences of the author as both an engineer and instructor. Each example demonstrates how the code and standard has been correctly and incorrectly applied.
This book is a no nonsense guide to the principle intentions of the codes or standards and provides advice on compliance. After using this book the reader should come away with a clear understanding of how piping systems fail and what the code requires the designer, manufacturer, fabricator, supplier, erector, examiner, inspector, and owner to do to prevent such failures. The focus of the book is to enhance participants? understanding and application of the spirit of the code or standard and form a plan for compliance. The book is enhanced by a multitude of calculations to assist in problem solving, directly applying the rules and equations for specific design and operating conditions to illustrate correct applications. Each calculation is based on a specific code. The major codes covered in the book are:

LAYMAN'S HANDBOOK ON HOW TO DEVELOP A SMALL HYDRO SITE 2nd Ed.
Title: LAYMAN’s Guidebook on how Develop a Small Hydro Site
Author: Celso Penche, Dr Ingeniero de Minas (U.Politécnica de Madrid)
Publication: June, 1998 Directorate General for Energy (DGXVII) European Commission
File: PDF 11.7MB, 266 Pages
Book Description:
Taken from Introduction: This handbook, an updated version of the original Layman’s Handbook on how to develop a Small Hydro Site, published by the Commission in 1993, has been written, in the frame of the ALTENER programme, under contract with the Commission of the European Communities (Directorate General for Energy, DG XVII). It has not been designed to replace professional expertise but it is hoped it is comprehensive enough to advise laymen on all necessary procedures that should be followed to develop a site. However its content includes enough technical information, so a non-specialist engineer would be able to produce a primary feasibility report.
Contents:
■Introduction [ A free fuel resource potentially everlasting. ~ Definition of small hydropower ~ Site configurations ~ Planning a small hydropower scheme ]
■2 Fundamentals of Hydraulic Engineering [ Introduction ~ Water flow in pipes ~ Water flow in open channels ~ Computer programs ]
■3 The water resource and its potential [ Introduction ~ Evaluating streamflows by discharge measurements ~ Streamflow characteristics ~ Residual, reserved or compensation flow ~ Estimation of plant capacity and energy output ~ Firm energy . ]
■4 Site evaluation methodologies [ Introduction ~ Cartography ~ Geotechnical studies ~ Learning from failures ]
■5 Hydraulic structures [ Structures for storage and water intake ~ Onlinefreeebooks.net ~ Waterways ]
■6 Electromechanical equipment [ Powerhouse ~ Hydraulic turbines ~ Speed increasers ~ Generators ~ Turbine control ~ Switchgear equipment ~ Automatic control ~ Ancillary electrical equipment ~ Examples. ]
■7 Environmental impact and its mitigation [ Introduction ~ Burdens and impacts identification ~ Impacts in the construction phase ~ Impacts arising from the operation of the scheme ~ Impacts from transmission lines ~ Conclusions ]

This document serves as the Reference Manual for the 1½-day FHWA workshop on concrete pavement preservation. The purpose of the document is to provide the most up-to-date information available on the design, construction, and selection of cost-effective concrete pavement preservation strategies. It concentrates primarily on strategies and methods that are applicable at the project level, and not at the network level, where pavement management activities function and address such issues as prioritizing and budgeting.
Detailed information is presented on seven specific concrete pavement preservation treatments: slab stabilization, partial depth repairs, full-depth repairs, retrofitted edge drains, load transfer restoration, diamond grinding, and joint resealing. In addition, information is provided on pavement evaluation techniques and strategy selection procedures.

Integrated Materials and Construction Practices for Concrete Pavement
Library of Congress Catalog Card Number: 2006936814
ISBN: 978-0-9652310-9-1
File Format: PDF - 355 pages (high quality) - 18 Mb file size
This manual provides a ready reference and/or instruction guide for anyone involved in designing or constructing concrete pavements. The emphasis is on the concrete material itself—specifically, on optimizing concrete’s performance. To optimize concrete’s performance in today’s pavement construction environment, everyone in concrete paving projects must understand concrete as the central component of a complex, integrated pavement system.
Readers will find some overlap and repetition of information among the chapters. This is a result of the integrated nature of the various stages and considerations involved in designing and constructing concrete pavement projects.
