Description:
The book has two aims: to introduce basic concepts of environmental modeling and to facilitate the application of the concepts using modern numerical tools such as MATLAB. It is targeted at all natural scientists dealing with the environment: process and chemical engineers, physicists, chemists, biologists, biochemists, hydrogeologists, geochemists and ecologists.
MATLAB was chosen as the major computer tool for modeling, firstly because it is unique in it's capabilities, and secondly because it is available in most academic institutions, in all universities and in the research departments of many companies.

The objective of this book is to describe the numerical methods for modeling water waves that have been developed primarily at the Los Alamos National Laboratory over the last four decades and to describe some examples of the applications of these methods. Some of the applications of the numerical modeling methods were performed while the author was working at the Joint Institute for Marine and Atmospheric Research at the University of Hawaii, some as Mader Consulting Co. research projects, and the rest as a Fellow of the Los Alamos National Laboratory.

BS EN 12810:2003 Facade scaffolds made of prefabricated components
BS EN 12810-1:2003 Facade scaffolds made of prefabricated components. Product specifications
BS EN 12810-1:2003 specifies the performance requirements and the general requirements for the structural design and assessment of prefabricated façade scaffold systems. The façade scaffolds are intended for use while connected to the façade with ties. It is limited to façade scaffold systems that have standards made of steel or aluminium alloy and have other elements made of these materials or timber based materials. It defines a standard set of system configurations under which the structural design is carried out.
This standard does not specify requirements for protection fans. It does not give information about erection, use, dismantling or maintenance.
BS EN 12810-2:2003 Facade scaffolds made of prefabricated components. Particular methods of structural design
This European standard applies to façade scaffold systems conforming with EN 12810-1. It defines rules for the
structural analysis and design of these systems by calculation and testing, in addition to those defined in
EN 12811-1,prEN 12811-2, EN 12811-3 and EN 12810-1.
Basic requirements are given in ENV 1993-1-1 and ENV 1999-1-1.

Physical Geology is the first introductory course in the field of Geology. The faculty and staff of Lamar University, Department of Earth and Space Sciences have collaborated to produce a laboratory manual that is informative and easily understood. It has been customized to present the concepts and ideas the faculty feel are most important in Physical Geology. It is intended to supplement the main lecture course by exposing the student to conceptual exercises and hands-on experience of the subjects introduced in lecture.

This book is concerned with the fundamental principles of guidance and stability, which are a consequence of the mechanics of wheel-rail interaction as embodied in the equations of motion. For research purposes, where the objective is to achieve an understanding of an innovative system or a particular problem, simple models can be very useful and can provide productive insights. Analytical studies which describe the mechanics of various phenomena by the simplest model possible can be used to explore new suspension and vehicle design concepts.

Commentary on BS 5400-3: 2000 Code of practice for the design of steel bridges SCI PUBLICATION P295
The use of steel and composite construction for bridges is now recognised as economical over a wide range of spans and is versatile in the many forms in which it may be applied. This Commentary is one of several documents published by The Steel Construction Institute to provide guidance for the designers of steel and composite bridges. The guides are intended for practising engineers, to enable them to apply the design codes with ease.
The Commentary discusses in detail the provisions in the clauses of BS 5400-3:2000, provides background information where appropriate and comments on their practical application. The comments and discussion represent the considered opinion of experienced engineers and researchers. In some cases information about the basis of the clauses has been difficult to obtain; for such cases, the commentary presents the consensus view of the background to these clauses.
The scope of this publication is limited to those aspects of BS 5400-3: 2000 most commonly used by bridge designers. Comments are given on a clause-by-clause basis. The design of cross frames and diaphragms in box girder design (Clauses 9.16 and 9.17) is not discussed.
The Commentary is intended as a reference document to be used in conjunction with the Code. References and comparisons are made to other codes where appropriate (viz. BS 5950, BS EN 10025 and BS 153). References are given at the end of each principal Section and are referred to in the text in the form[2.3], where ‘2’ indicates Section 2 and ‘3’ is the third reference in that Section.

This document is a guide to the design of stainless steel structures for engineers. The guide gives design recommendations, design examples, section properties and member capacities for commonly used stainless steel sections. This guide applies to the design of the grades of stainless steel that are widely used in structural applications, including the austenitic grades 1.4301 (304), 1.4401 (316) and their low carbon variants. Duplex grades 1.4362 (SAF 2304) and 1.4462 (2205) are also covered. The recommendations on structural design given in the guide have, as far as is practicable, been harmonized with BS 5950-1: 2000. The guide gives recommendations on how to select the most appropriate grade of stainless steel for a given application. It provides information on the mechanical properties, physical properties and design strength of stainless steel. The guide covers aspects of material behaviour, cross-section design, member design, connections, fabrication and fire resistant design. Design examples are included to illustrate the use of the design recommendations.
Based on these design recommendations, a comprehensive set of design tables is presented, giving gross and effective section properties, section classification and member capacities for a wide range of cold formed stainless steel sections. The structural forms covered by the design tables are circular, rectangular and square hollow sections, channels, double channels back to back, equal angles and equal angles back to back. The grades of stainless steel covered in the tables are austenitic stainless steel grades 1.4301 (304), 1.4401 (316), 1.4404 (316L) and the duplex grades 1.4362 (SAF 2304) and 1.4462 (2205).

The purpose of this guide is to advise structural engineers, architects and fabricators of the properties and capabilities of iron, carbon steel and stainless steel castings. It emphasises that the high strength, ductility and toughness of these castings, coupled with their efficient production method, offer cost-effective solutions for a variety of structural components. Additionally, castings have excellent surface finish, together with good welding and machining characteristics. Functional shapes can be streamlined to give the best combination of strength, stiffness, slenderness and weight, thus saving on materials and minimising manufacturing costs. The guide explains the basic processes and techniques of casting and provides information for the designer on welding, surface finishes, tolerances and inspection and testing methods. The guide emphasises that the specification of the correct casting techniques and the appropriate level of quality are very important and require close liaison between the foundry and the design and construction teTahme .
procurement process is explained and illustrated with flowcharts. Appendices give exampleos f recent projects using structural castings, including four detailed case histories featuring main trussc onnections, glazing connections, beam to column connections and compression members in a bridge. Lists of sources of further information and the addresses of some UK foundries are also given.
