World Wind lets you zoom from satellite altitude into any place on Earth.
NASA thanks Sun Microsystems for their support in the development of World Wind Java. This generous support has led to the very artful and exemplary use of the Java OpenGL API. The possibilities for portable, high-performance 3D graphics rendering are now wide open

This practical text is an essential source of information for those wanting to know how to deal with the variability that exists in every engineering situation. Using typical engineering data, it presents the basic statistical methods that are relevant, in simple numerical terms. In addition, statistical terminology is translated into basic English.
In the past, a lack of communication between engineers and statisticians, coupled with poor practical skills in quality management and statistical engineering, was damaging to products and to the economy. The disastrous consequence of setting tight tolerances without regard to the statistical aspect of process data is demonstrated.
This book offers a solution, bridging the gap between statistical science and engineering technology to ensure that the engineers of today are better equipped to serve the manufacturing industry.
Inside, you will find coverage on:
* the nature of variability, describing the use of formulae to pin down sources of variation;
* engineering design, research and development
, demonstrating the methods that help prevent costly mistakes in the early stages of a new product;
* production, discussing the use of control charts, and;
* management and training, including directing and controlling the quality function.
The Engineering section of the index identifies the role of engineering technology in the service of industrial quality management. The Statistics section identifies points in the text where statistical terminology is used in an explanatory context.
Engineers working on the design and manufacturing of new products find this book invaluable as it develops a statistical method by which they can anticipate and resolve quality problems before launching into production. This book appeals to students in all areas of engineering and also managers concerned with the quality of manufactured products.
Academic engineers can use this text to teach their students basic practical skills in quality management and statistical engineering, without getting involved in the complex mathematical theory of probability on which statistical science is dependent.

Seismic Design of Cast-in-Place Concrete Diaphragms, Chords, and Collectors : A Guide for Practicing Engineers
Author: Moehle, Jack P., Hooper, John D., Kelly, Dominic J., and Meyer, Thomas R. | Size: 1.8 MB | Format:PDF | Publisher: NIST | Year: 2010 | pages: 33 | ISBN: none
Building structures generally comprise a three-dimensional framework of structural elements configured to support gravity and lateral loads. Although the complete three-dimensional system acts integrally to resist loads, we commonly conceive of the seismic force-resisting system as being composed of vertical elements, horizontal elements, and the foundation (Figure 1-1). The vertical elements extend between the foundation and the elevated levels, providing a continuous load path to transmit gravity and seismic forces from the upper levels to the foundation. The horizontal elements typically consist of diaphragms, including collectors. Diaphragms transmit inertial forces from the floor system to the vertical elements of the seismic force-resisting system. They also tie the vertical elements together and thereby stabilize and transmit forces among these elements as may be required during earthquake shaking. Diaphragms are thus an essential part of the seismic force-resisting system and require design attention by the structural engineer to ensure the structural system performs adequately during earthquake shaking.

Strength of Materials (Materials Science and Technologies Series)
Author: Gustavo Mendes, Bruno Lago | Size: 10.2 MB | Format:PDF | Publisher: Nova Science Publishers | Year: 2009-09-25 | pages: 272 | ISBN: 1607415003 9781607415008
The strength of a material refers to the material's ability to withstand an applied stress without failure. The applied stress may be tensile, compressive, or shear. A material's strength is dependent on its micro structure. The engineering processes to which a material is subjected can alter this microstrucure. This book provides a variety of material strength research including an extensive overview on the state of the art ceramic composite material BIOLOX delta which, since 2001, has successfully implanted more than 500,000 artificial hip joints. Due to the unique strength and toughness of this material, the risk of fracture has been substantially reduced when compared to conventional ceramic materials. Several different aspects of ionomer research from a physical property standpoint is discussed as well, including the history and current trends in ionomer research and a discussion on the immediate needs in this field. Furthermore, particle modeling (PM) as an innovative particulate dynamics based modeling approach is examined as a robust tool for simulating fracture problems of solids under extreme loading conditions, including situations of collapse, impact, blasting or high strain rate tension/compression. This book includes research on the ability of particle modeling to correctly predict dynamic fragmentation of materials with good accuracy.

This book presents the basic principles of soil dynamics, and a variety of solutions of practical interest for geotechnical engineering, geophysics and earthquake engineering. Emphasis is on analytical solutions, often including the full derivation of the solution, and giving the main parts of computer programs that can be used to calculate numerical data. Reference is also made to a website from which complete computer programs can be downloaded. Soil behaviour is usually assumed to be linear elastic, but in many cases the effect of viscous damping or hysteretic damping, due to plastic deformations, is also considered.
Special features are: the analysis of wave propagation in saturated compressible porous media, approximate analysis of the generation of Rayleigh waves, the analysis of the response of soil layers to earthquakes in the deep rock, with a theoretical foundation of such problems by the propagation of Love waves, and the solution of such basic problems as the response of an elastic half space to point loads, line loads, strip loads and moving loads.
A CD accompanies this book containing programs for waves in piles, propagation of earthquakes in soils, waves in a half space generated by a line load, a point load, a strip load or a moving load, and the propagation of a shock wave in a saturated elastic porous material. The book contains the source code for the main functions of these programs.

This book presents a systematic approach to numerical solution for a wide range of spatial contact problems of geotechnics. On the basis of the boundary element method new techniques and effective computing algorithms are considered. Special attention is given to the formulation and analysis of the spatial contact models for elastic bases. Besides the classical schemes of contact deformation, new contact models are discussed for spatially nonhomogeneous and nonlinearly elastic media properly describing soil properties.
