Understanding wood: a craftsman's guide to wood technology
Title: Understanding Wood
A craftsman's guide to wood technology
Author: R. Bruce Hoadley
Published by: The Taunton Press
63 South Main, PO Box 5506
Newton, CT 06470-5506
ISBN 1-56158-358-8
In this essential reference for woodworkers, R. Bruce Hoadley explains everything from how trees grow to how best to cut, season, machine, join, bend, and finish wood. Why do miters open and glue joints loosen? How do you get a really sharp edge? Examples of problems and solutions help woodworkers puzzle through their own projects, while full-color photos and helpful tables illustrate key points.
Wood is a complex, dynamic material that can only be used successfully if the craftsperson understands it. It reacts to changes in humidity, and the various species have widely different working and structural properties (in addition to their many colors and textures). Both Hoadley and Peters do a good job of helping readers understand the factors that must be considered when using wood and products such as plywood. A frequent writer on home improvement topics, Peters offers a colorful book geared toward hobbyist woodworkers. He covers the process of making lumber from start to finish, including how trees grow, their structure, common ways of milling and drying lumber, grading, and possible defects found in wood. One section shows wood samples (both finished and plain) and describes their basic working characteristics. This particularly attractive book is filled with colorful photographs and illustrations and includes both a glossary and an excellent appendix showing the hazards posed by the sawdust of specific wood species. Hoadley, a professor of wood science and technology, has revised his classic title for its 20th anniversary. While the original is still great, the new title incorporates the latest technologies in adhesives, finishes, and wood products. Color photographs are a welcome addition as the original edition's photos were drab and unappealing. Hoadley covers much of the material that Peters does but in far greater depth. While this complexity may intimidate beginners, it is just what advanced users and professionals need. For example, Hoadley's wood identification section consists of macrophotographs of wood samples magnified ten times so that the correct species can be determined from the pattern of wood cells. This title also includes an in-depth glossary, bibliography, and index. Hoadley's work is an improvement of a classic while Peters's is good enough that it will likely stand the test of time as well. The difference is in complexity, not quality. General public library collections will get more use from Peters's title, while in-depth public and academic libraries will want Hoadley.

This is a classic article published in 1968 that proposed a foundation of probabilistic method in seismic hazard analysis. Many scientists are agreed this paper is pioneered in probabilistic seismic hazard analysis method.
Cornell, CA (1968). Engineering Seismic Risk Analysis, Bulletin of the Seismological Society of America. Vol. 58, No. 5, pp. 1583-1606.
This paper introduces a method for the evaluation of the seismic risk at the site of an engineering project. The results are in terms of a ground motion parameter (such as peak acceleration) versus average return period. The method incorporates the influence of all potential sources of earthquakes and the average activity rates assigned to them. Arbitrary geographical relationships between the site and potential point, line, or areal sources can be modeled with computational ease.

New version and new medicine not detected as virus
DPlot graphs and manipulates 2D and 3D data from a variety of sources in many different formats. While designed for scientists, engineers, and other technical fields, DPlot's straightforward interface will appeal to anybody interested in creating presentation-quality X-Y plots and/or contour plots of 3D data. DPlot runs on Windows 95, 98, 2000, ME, NT, 2003, XP, Vista, and 2008.
DPlot include these features:
• Multiple scaling types, including linear, logarithmic, and probability scales on the X and/or Y axes.
DPlot also provides several special purpose scale types, including grain size distribution plots, tripartite grids (shock spectra), polar charts, triangle plots, N1.85 hydraulic scales, and Mercator projection.
• DPlot Jr now supports file export plugins. It is distributed with image export plugins for BMP, GIF, JPG, PNG, and TIF formats.
• The legend in XY plots may now contain line breaks (using the character sequence \n) in the same way that the title lines and axis labels do.

IMPORTANT NOTICE: You may use this software for evaluation purposes only.
If you like it, it is strongly suggested you buy it to support the developers.
By any means you may not use this software to make money or use it for commercial purpose.
This is a wellknown article in performance-based earthquake engineering which is authored by Dr. Vamvatsikos and the late Prof. Cornell.
Dimitrios Vamvatsikos and C. Allin Cornell (2002). Incremental dynamic analysis, Earthquake Engineering Structural Dynamics; 31:491–514.
Incremental dynamic analysis (IDA) is a parametric analysis method that has recently emerged in several different forms to estimate more thoroughly structural performance under seismic loads. It involves subjecting a structural model to one (or more) ground motion record(s), each scaled to multiple levels of intensity, thus producing one (or more) curve(s) of response parameterized versus intensity level.
