"Spreadsheets in Science and Engineering" shows scientists and engineers at all levels how to analyze, validate and calculate data and how the analytical and graphic capabilities of spreadsheet programs (ExcelR) can solve these tasks in their daily work. The examples on the CD-ROM accompanying the book include material of undergraduate to current research level in disciplines ranging from chemistry and chemical engineering to molecular biology and geology.

This book will help structural geologists keep abreast of rapid changes in work practices resulting from the personal computer revolution. It is organized into six parts: I Computer-Aided Learning; II Microstructural Analysis; III Analysis of Orientation Data; IV Strain and Kinematic Analysis; V Mathematical and Physical Modeling; VI Structural Mapping and GIS. The 45 contributing authors explain how to: set up computer-aided teaching and learning facilities on a low budget; illustrate tectonic strain concepts with a drawing program; integrate multimedia presentations into structural coursework; analyze microstructures with computer-aided microscopy; produce sophisticated stereonets with custom software for both the Mac and IBM PC; evaluate orientation data using a spreadsheet program; model the development of macrostructures and microstructures numerically; integrate structural and geophysical data; and apply PC technology to the production of structural maps, cross sections, and block diagrams. The editor's own contributions reveal the inner workings of his renowned structural research applications which are used in hundreds of universities worldwide. Commercial and non-commercial applications of particular interest to structural geologists are reviewed.This volume will prove an invaluable resource for professors, instructors, and research students, as well as research scientists in the public services and exploration industries. If you are such a person, have you lectured with the aid of a gyroscopic mouse? Or used Bézier curves to model heterogeneous deformation? Or analyzed a fold structure using a digital terrain model? If not, you'll need to rush out and buy this book before the next wave of new technology hits!

Most geoscientists are aware of recent IT developments, but cannot spend time on obscure technicalities. Few have considered their implications for the science as a whole. Yet the information industry is moving fast: electronic delivery of hyperlinked multimedia; standards to support interdisciplinary and geographic integration; new models to represent and visualize our concepts, and control and manage our activities; plummeting costs that force the pace. To stay on course, the scientist needs a broad appreciation of the complex and profound interactions of geoscience and IT, not previously reviewed in a single work.The book brings together ideas from many sources, some probably unfamiliar, that bear on the geoscience information system. It encourages readers to give thought to areas that, for various reasons, they have taken for granted, and to take a view on forces affecting geoscience, the consequences for themselves and their organisations, and the need to reconsider, adapt and rebuild.Practicing geoscientists with a general interest in how IT will affect their work and influence future directions of the science; geoscientists familiar with IT applications in their own specialist field who need a broader perspective; and students or educators specializing in IT applications in geoscience who require a top-down overview of their subject will find this title valuable. The IT background from this book should help geoscientists build a strategy for the new century.

This unique book is the key to computer contouring, exploring in detail the practice and principles using a personal computer. Contouring allows a three dimensional view in two dimensions and is a fundamental technique to represent spatial data. All aspects of this type of representation are covered including data preparation, selecting contour intervals, interpolation and griding, computing volumes and output and display. Formulated for both the novice and the experienced user, this book initially conducts the reader through a step by step explanation of PC software and its application to personal data, and then presents the rationale and concepts for contouring using the computer. Accompanying the book is a set of BASIC programs, in ASCII format, on an MS-DOS 360KB floppy disk. These programs implement eighteen interpolation methods, five gradient estimation techniques, and seven types of display, and are designed to be adapted or combined to suit a wide range of possible objectives concerning either the comparative study of contouring methodology or the practical production of contour displays.

The book introduces procedures for simulating migration and entrapment of oil in three dimensions in sequences of sandstones and shales. A principal purpose is to show how simulation experiments can represent oil migration routes and predict places where oil may be trapped in sandstones and intercalated shales. The book derives the differential equations used to represent three-dimensional motions of porewater and oil in sedimentary sequences, and shows how the equations may be transformed into finite form for numerical solution with computers. There is emphasis on the graphic display of solutions, and results of example theoretical and actual applications are presented. The book is directed to geologists who have backgrounds in mathematics and computing and who are engaged in oil exploration and production.
