Materials with nanoscale structure (i.e. a structure of less than 100 nanometers in size) represent a new and exciting field of research. These materials can be produced in many ways, possess a number of unique properties compared with coarser-scaled structures, and have several possible applications with significant technological importance. Based on a state-of-the-art survey of research findings and commercial prospects, this new book concludes that much work remains to be done in characterizing these structures and their exceptional properties, and presents recommendations for the specific research and development activities needed to fill these gaps in our understanding.

A Challenge of Numbers describes the circumstances and issues centered on people in the mathematical sciences, principally students and teachers at U.S. colleges and universities. A healthy flow of mathematical talent is crucial not only to the future of U.S. mathematics but also as a keystone supporting a technological workforce. Trends in the mathematical sciences' most valuable resource--its people--are presented narratively, graphically, and numerically as an information base for policymakers and for those interested in the people in this not very visible, but critical profession.

Aggressive, effective safety inspection programs are key elements to ensuring that oil- and gas-producing platform operations on the outer continental shelf are conducted in a safe and environmentally sound manner. Although the oil and gas leaseholders themselves are primarily responsible for the soundness of their operations, the Minerals Management Service (MMS) of the Department of the Interior is charged with prescribing safe practices and inspecting platforms. In response to an MMS request, this book examines possible revisions of MMS's inspection system, appraises inspection practices elsewhere--both in government and industry--assesses the advantages and disadvantages of alternative procedures, and recommends potentially more efficient practices aimed at increasing industry's awareness of its accountability for safety.

The flood that greeted the new year in 1988 brought home the uncomfortable realization that many suburban areas of eastern Oahu are at risk from sudden and, in some cases, unpredictable flooding. Torrential rains fell over the southeastern portion of the island on New Year's Eve, precipitating major flooding in several suburban neighborhoods and resulting in $34 million in damages. Neither the current meteorological capabilities nor the present flood control structures for the Oahu area proved adequate to predict or control the deluge. This book documents and analyzes the meteorological conditions leading to the torrential rains, the causes and patterns of flooding, the performance of flood control structures in affected areas, the extent of damages, and the effectiveness of the local emergency response and recovery actions. Conclusions and recommendations are drawn from the analyses.

Unified life-cycle engineering (ULCE), or concurrent engineering, is a design engineering environment in which computer-aided design technology is used to assess and improve the quality of a product--not only during the active design phases but throughout its entire life cycle. This is achieved by integrating and optimizing the design attributes for producibility and supportability as well as for performance, operability, cost, and schedule. This book addresses ULCE approaches to design, manufacture, and application of structural components--especially for advanced military systems. Conclusions and recommendations to support the development of an effective ULCE design engineering environment are presented.

Each time we see grim pictures of aircraft wreckage on a rain-drenched crash site, or scenes of tired holiday travelers stranded in snow-covered airports, we are reminded of the harsh impact that weather can have on the flying public. This book examines issues that affect the provision of national aviation weather services and related research and technology development efforts. It also discusses fragmentation of responsibilities and resources, which leads to a less-than-optimal use of available weather information and examines alternatives for responding to this situation. In particular, it develops an approach whereby the federal government could provide stronger leadership to improve cooperation and coordination among aviation weather providers and users.
