Product Description:
More than 50% of the world's population already live in cities, and the proportion is rising extremely rapidly towards developed country levels of more than 90%. Groundwater from wells is the major source of water supply for many of these cities, however, groundwater is polluted by the cities that overlie it and sewerage systems are often absent, or leak. Industrial landuse implies the use of large quantities of chemicals, and it is the poor disposal and accidental spillage of these chemicals which results in the contamination of virtually every industrial site in the world. Much of this pollution migrates deeper to damage groundwater. Groundwater has slow turnover time, often measured in decades and centuries, reducing the self-cleansing capacity. Urban aquifers are therefore vitally important but very fragile, easily damaged and slow to repair. Urban groundwater problems and solutions vary greatly around the world. Mature cities often have remote and clean water supplies, good sewerage systems, strict controls on groundwater and land use, and declining industries. However, they have a legacy of more than one hundred years of waste disposal and industrially-contaminated land which continues to cause problems. Rapidly urbanising cities are frequently dependent on local groundwater and have poor sanitation and uncontrolled industry. These factors present many immediate risks to human health. This book explains the nature and value of urban groundwater, discussing the types of pollutants that are found, and their sources. The unique aspect of this book is the in-depth discussion of six different urban environments, complete with case studies. These environments are: Mature industrial cities; Arid-zone cities; Weathered crystalline aquifers in sub-Saharan Africa; Cities overlying karst aquifers; Alluvial aquifer systems; Shallow aquifers in Mediterranean climates.

Book Description:
Real-world problems and data sets are the backbone of this book, which provides a unique approach to the topic, integrating statistical methods, data analysis, and applications. Now extensively revised, the book includes new information about mixed effects models, applications of the MIXED procedure, regression diagnostics with the corresponding IML procedure code, and covariance structures. The authors' approach to the information will aid professors, researchers, and students in a variety of disciplines and industries. Extensive SAS code and the corresponding high-resolution output accompany sample problems, and clear explanations of SAS procedures are included. Emphasis is on correct interpretation of the output to draw meaningful conclusions. Featuring both the theoretical and the practical, topics covered include multivariate analysis of experimental data and repeated measures data, graphical representation of data including biplots, and multivariate regression. In addition, a quick introduction to the IML procedure with special reference to multivariate data is available in an appendix. SAS programs and output integrated with the text make it easy to read and follow the examples.

Mechanical Behavior of Multi-Spherical Sliding Bearings
Author: Daniel M. Fenz and Michael C. Constantinou | Size: 4.08 MB | Format:PDF | Publisher: MCEER | Year: 2008 | pages: 186
This report describes the principles of operation and the development of cyclic force-displacement relationships for three variations of multi-spherical sliding bearings: the double FP bearing, the triple FP bearing, and the modified single FP bearing. The force-displacement relationships of devices with increasingly complex behavior were determined by extending the fundamental principles of operation that apply to sliding on a single concave surface. It was shown that each device is capable of exhibiting displacement dependent adaptive behavior, i.e., desirable changes in stiffness and damping over the course of motion. These changes are determined by the relative values of each surface’s coefficient of friction, effective radius of curvature, and displacement capacity. Since all are predefined design parameters (aside from the inherent uncertainty and variability in the coefficient of friction), their behavior is completely controllable by the engineer. In addition, it was shown that in cases where multiple surfaces are of equal friction, the complexity of behavior exhibited by these devices is reduced. This is important because bearings of smaller plan dimension can still use familiar and proven methods of analysis and design, resulting in significant cost savings. A future report will detail the development, experimental verification and application of tools for dynamic analysis of structures isolated with these bearings.
