HDPE Geomembranes in Geotechnics
HDPE (High-density polyethylene) geomembranes are nowadays widely used for large-area liners and construction sealings in geotechnical engineering. Lining of water ponds, dams and dykes, landfill base liners and cover systems, remediation of contaminated sites, waterproof for tunnels, beneath highways and for various other civil engineering constructions are a few examples of application. The book covers all aspects of the HDPE geomembrane field: HDPE materials, geomembrane manufacture, textured geomembranes, properties, long-term performance and testing, installation and welding of geomembranes, quality assurance and control, leak detection, standards, recommendations and regulations. Various important topics are treated in detail. As part of it, the basic physical and chemical facts necessary to fully understand HDPE geomembrane properties and performance are carefully developed and explained.
Geotechnics of Roads : Fundamentals
Presents stresses and strains in road structures, water and heat migration within and between layers of road materials, and the effects of water on the strength and stiffness of those materials. It includes a deep analysis of soil compaction, one of the most important issues in road construction. Compaction accounts for only a small proportion of a construction budget but its effects on the long-term performance of a road are decisive. In addition, the book describes methodologies for nondestructive road evaluation including analysis of continuous compaction control, a powerful technique for real-time quality control of road structures.
Geological Storage of Highly Radioactive Waste : Current Concepts and Plans for Radioactive Waste Disposal
The book describes and assesses current concepts for long-term disposal of highly radioactive waste. Different types of rock are discussed and assessed with respect to practical difficulties in construction of a repository, and the efficiency in isolating radioactive waste. Safety matters are most important and are treated in the respective chapters and in a final, conclusive chapter. Cost issues and related quality matters are discussed for the case of constructing a virgin repository and repositories in the form of converted abandoned mines.
CCD Image Sensors in Deep-Ultraviolet : Degradation Behavior and Damage Mechanisms
As the deep-ultraviolet (DUV) laser technology continues to mature, an increasing number of industrial and manufacturing applications are emerging. For example, the new generation of semiconductor inspection systems is being pushed to image at increasingly shorter DUV wavelengths to facilitate inspection of deep sub-micron features in integrated circuits. DUV-sensitive charge-coupled device (CCD) cameras are in demand for these applications. Although CCD cameras that are responsive at DUV wavelengths are now available, their long-term stability is still a major concern. This book describes the degradation mechanisms and long-term performance of CCDs in the DUV, along with new results of device performance at these wavelengths.
