  • This book provides a modern and basic introduction to a branch of international law constantly gaining in importance in international life, namely international humanitarian law (the law of armed conflict). It is constructed in a way suitable for self-study. The subject matters are discussed in self-contained chapters, allowing each to be studied independently of the others.

  • In response to the enactment by the U.S. Congress of the Intermodal Surface Transportation Efficiency Act (ISTEA), the Federal Highway Administration (FHWA) requested that the National Research Council (NRC) conduct a study on nonconventional concrete technology for renewal of the highway infrastructure. ISTEA directed the FHWA to initiate a comprehensive, long-range infrastructure research and development (R&D) program.

  • That philosophy is "materialism", which holds a number of bogus views about why and how we came into being. Materialism maintains that there is nothing but the matter and that matter is the essence of everything, be it organic or inorganic. Starting out from this premise, it denies the existence of a divine Creator, that is, Allah. Reducing every- thing to the level of matter, this notion transforms man into a creature that heeds only matter and turns away from moral values of whatever kind. This is the beginning of big disasters that will befall a man's life....

  • In the past decades, significant advances in tribology have been made as engineers strive to develop more reliable and high performance products. The advancements are mainly driven by the evolution of computational techniques and experimental characterization that leads to a thorough understanding of tribological process on both macro- and microscales.

  • In the early 1970s, the United States government identified and became wary of hazardous materials in soil, surface water, groundwater, and building structures. Most of these contaminants resulted from the evolution of technology without the benefit of chemical regulatory controls. The cost for cleanup of such sites was projected to exceed a trillion dollars, the burden of which was to be borne by the taxpayer and responsible parties. The term “responsible party” is a broad term but, in the final analysis, a responsible party is usually a property owner....

  • Reporting that rare species are more abundant on larger islands, they make the case for greater conservation efforts on larger islands. In the next chapter, Hugo Mejía-Madrid evaluates the roles of heterochrony and ecological fitting in the evolution of helminth fish parasites. Contrary to expectations, helminth speciation lags substantially behind that of their hosts, tending to occur in pulses associated with continent jumps among hosts. Next in this section, Toshiharu Mita et al.

  • In the past several years, there have been many developments in the materials for lead–acid batteries. Silver in grid alloys for high temperature climates in SLI batteries has increased the silver content of the recycled lead stream. Concern about silver and other contaminants in lead for the active material for VRLA batteries led to the initiation of a study by ALABC at CSIRO. The study evaluated the effects of many different impurities on the hydrogen and oxygen evolution currents in float service for flooded and VRLA batteries at different temperatures and potentials. ...

  • In recent years, it was realized that the Multiple Input Multiple Output (MIMO) communication systems seems to be inevitable in accelerated evolution of high data rates applications. The MIMO systems, have received considerable att ention of researchers and commercial companies due to their potential to dramatically increase the spectral effi ciency and simultaneously sending individual information to the corresponding users in wireless systems.

  • Since the first edition of this handbook, semiconductor technology has gone through a continued evolution of new devices and materials like never before. Wafer sizes continue to grow with most of the new fabs equipped for 12-inch wafers. The changes are triggered by many considerations: continued need to provide more functions at lower cost; technology features less than 1000 Å requiring new processes, and exponential increase in the number of device elements.

  • Since the birth of the field of optical biosensors, the pace of evolution of this field has been swift. While myriad reports have appeared describing applications and advancements in optical biosensor technology, few existing volumes are dedicated to a synopsis of this field. Since the development of optical biosensors mirrors the advances in the rapidly evolving telecommunications industry, we deemed the time to be ripe for such an opus.

  • This thesis presents time-resolved measurements of the spin evolution of transient carrier populations in III-V quantum wells. Non-equilibrium distributions of spin polarisation were photoexcited and probed with picosecond laser pulses in three samples; a high mobility modulation n-doped sample containing a single GaAs/AlGaAs quantum well, an In0.11Ga0.89As/GaAs sample containing three quantum wells and, a multi-period GaAs/AlGaAs narrow quantum well sample.

  • In a 1786 letter to a friend, Thomas Jefferson called for “the diffusion of knowledge among the people. No other sure foundation can be devised for the preservation of freedom and happiness.”1 Jefferson saw clearly what has become increasingly evident since then: the fortunes of a nation rest on the ability of its citizens to understand and use information about the world around them. We are about to enter a century in which the United States will be even more dependent on science and technology than it has been in the past.

  • Robots can be considered as the most advanced automatic systems and robotics, as a technique and scientific discipline, can be considered as the evolution of automation with interdisciplinary integration with other technological fields. A robot can be defined as a system which is able to perform several manipulative tasks with objects, tools, and even its extremity (end-effector) with the capability of being reprogrammed for several types of operations.

  • My primary purpose in writing and revising this book has been to provide an updated introduction to the history of medicine. Although the text began as a ‘‘teaching assistant’’ for my own one-semester survey course, I hope that this new edition will also be of interest to a general audience, and to teachers who are trying to add historical materials to their science courses or science to their history courses.

  • This book deal with the modern developing of microwave and millimeter wave technologies. The first chapter is aimed at describing the evolution of technological processes for the design of passive functions in millimetre-wave frequency range. From the results HR SOI seems to be a good candidate in the coming year to address both low cost and low power mass market CMOS digital and RF/ MMW applications.

  • Differential evolution is one of the most recent global optimizers. Discovered in 1995 it rapidly proved its practical efficiency. This book gives you a chance to learn all about differential evolution. On reading it you will be able to profitably apply this reliable method to problems in your field. As for me, my passion for intelligent systems and optimization began as far back as during my studies at Moscow State Technical University of Bauman, the best engineering school in Russia. At that time, I was gathering material for my future thesis.
