This book is an introduction to surgery theory: the standard classification method for high-dimensional manifolds. It is aimed at graduate students, who have already had a basic topology course, and would now like to understand the topology of high-dimensional manifolds.

Hello
I had been developing a spreadsheet for the calculation of Elastic settlements in foundations on granular soils using theory of Elasticity . I had problem for calculating "Depth Influence Factor" . I can only find a chart in literature generated using Fox's (1948) equation from where every time i had to read values and insert in the cell.
Can any one guide me that how can I find this Fox's equation or any other alternate way to get this factor without reading chart for every time.

I'm looking for the following parts of ISO 17123 Optics and optical instruments - Field procedures for testing geodetic and surveying instruments:
Part 1 - Theory
Part 3 - Theodolites
Part 4 - Electro-optical distance meters
Part 5 - Electronic tacheometers
Any edition (standard, draft, for comment) would be appreciated.
Nuclear Safety is a comprehensive reference for heath & safety and engineering professionals in the nuclear industry and related bodies, including regulatory authorities, environmental and energy scientists, students, researchers and consultants.
It provides the methods and data needed to evaluate and manage the safety of nuclear facilities and related processes using risk-based safety analysis, and provides readers with the techniques to assess the consequences of radioactive releases.
The book covers relevant international and regional safety criteria (US, IAEA, EUR, PUN, URD, INI). The contents deal with each of the critical components of a nuclear plant, and provide an analysis of the risks arising from a variety of sources, including earthquakes, tornadoes, external impact and human factors. It also deals with the safety of underground nuclear testing and the handling of radioactive waste.
. Covers all plant components and potential sources of risk including human, technical and natural factors
. Brings together information on nuclear safety for which the reader would previously have to consult many different and expensive sources
. Provides international design and safety criteria and an overview of regulatory regimes
. Includes case studies and analysis of major accidents with data and calculations on accompanying website
Gianni Petrangeli has 40 years of experience in the nuclear industry. He was Director of the Departmental Area for Integrated Systems and New Technologies of ANPA, the Italian Regulatory body responsible for nuclear and industrial safety. He is a consultant to the United Nations Atomic Energy Agency and a researcher for nuclear safety for the European Commission. He lectures on Nuclear and Industrial Safety at the University of Pisa.

Minimization of welding distortion and buckling: Modelling and implementation >> Edited by P Michaleris, Penn State University, USA
Author: Edited by P Michaleris, Penn State University, USA | Size: 15.92 MB | Format:PDF | Quality:Original preprint | Publisher: Woodhead Publishing Limited | Year: May 2011 | pages: 314 | ISBN: ISBN 1 84569 662 X ISBN-13: 978 1 84569 662 7
- provides a systematic overview of the methods of minimizing distortion and buckling in welded structures
- focuses on understanding welding stress and distortion featuring computational welding mechanics and modelling the effect of phase transformations
- explores different methods of minimizing welding distortion discussing differential heating and dynamic thermal tensioning
Welding is a cost-effective and flexible method of fabricating large structures, but drawbacks such as residual stress, distortion and buckling must be overcome in order to optimize structural performance. Minimization of welding distortion and buckling provides a systematic overview of the methods of minimizing distortion and buckling in welded structures.
Following an introductory chapter, part one focuses on understanding welding stress and distortion, with chapters on such topics as computational welding mechanics, modelling the effect of phase transformations on welding stress and distortion and using computationally efficient reduced-solution methods to understand welding distortion. Part two covers different methods of minimizing welding distortion. Chapters discuss methods such as differential heating for minimizing distortion in welded stiffeners, dynamic thermal tensioning, reverse-side heating and ways of minimizing buckling such as weld cooling and hybrid laser arc welding.
With its distinguished editor and international team of contributors, Minimization of welding distortion and buckling is an essential reference for all welders and engineers involved in fabrication of metal end-products, as well as those in industry and academia with a research interest in the area.
