Blind Speech Separation
This is the first book to provide a cutting edge reference to the fascinating topic of blind source separation (BSS) for convolved speech mixtures. Through contributions by the foremost experts on the subject, the book provides an up-to-date account of research findings, explains the underlying theory, and discusses potential applications. The individual chapters are designed to be tutorial in nature with specific emphasis on an in-depth treatment of state of the art techniques. Blind Speech Separation is divided into three parts:Part 1 presents overdetermined or critically determined BSS. Here the main technology is independent component analysis (ICA). ICA is a statistical method for extracting mutually independent sources from their mixtures. Part 2 addresses underdetermined BSS, where there are fewer microphones than source signals. Here, the sparseness of speech sources is very useful; we can utilize time-frequency diversity, where sources are active in different regions of the time-frequency plane.Part 3 presents monaural BSS where there is only one microphone. Here, we can separate a mixture by using the harmonicity and temporal structure of the sources. We can build a probabilistic framework by assuming a source model, and separate a mixture by maximizing the a posteriori probability of the sources.
Blameworthy Belief : A Study in Epistemic Deontologism
Believing the wrong thing may sometimes have drastic consequences. The question as to when a person is not only ill-guided, but genuinely at fault for holding a particular belief is an important one: It touches upon the roots of our understanding of such notions as criminal negligence and moral responsibility. The answer to this question may influence the extent to which we are willing to submit each other to punishments ranging from mild resentment to harsh prison terms. This book presents an extensive effort to shed light on the conditions under which we may appropriately deem someone blameworthy for holding a particular belief. It regiments and unifies several debates within contemporary epistemology, ethics and legal scholarship. Finally, the book brings a new philosophical look on issues like our power to control beliefs and the extent and nature of foresight.

Bioremediation of Soils Contaminated with Aromatic Compounds
Environmental biotechnology, which was in its infancy in the early 80's, has evolved thanks to the revolution brought about by molecular biology. Multiple successes in the biological cleanup of civil and industrial wastewater and of hydrocarbon soil pollution, demonstrate the vast power of clean technologies. In addition, the buildup of information on the activities of microorganisms as catalysts in all sorts of natural, industrial and animal environments has flourished. There is a continuing realization of the critical role of microbial processes in biological, industrial and geological systems. Since environmental biotechnology has matured, it is ready to tackle bigger challenges: the scaling up of many bioremediation systems still in progress, the search for novel biocatalysts for industrial applications, the continuing effort against common human life-threatening processes such as antibiotic resistance, the accumulation of hormone-mimicking substances (endocrine disrupters), the deposition of air-borne pesticides in the environment and, the degradation of recalcitrant contaminants. These endeavors will help prevent the contamination of food chains, protect human life and allow for human activity and economic development that do not compromise environmental sustainabijity.

Biomineralization II : Mineralization Using Synthetic Polymers and Templates
In nature, biological organisms produce mineralized tissues such as bone, teeth, diatoms, and shells. Biomineralization is the sophisticated process of production of these inorganic minerals by living organisms. Construction of organic–inorganic hybrid materials with controlled mineralization analogous to those produced by nature has recently received much attention because it can aid in understanding the mechanisms of the biomineralization process and development of biomimetic materials processing. The biomineralization processes use aqueous solutions at temperatures below 100 ◦C and no toxic intermediates are produced in these systems. This series presents critical reviews of the present position and future trends in modern chemical research. The short and concise reports on chemistry are each written by world renowned experts. This series is still valid and useful after 5 or 10 years.

Biogeochemistry of Trace Elements in Arid Environments
Global warming has worsened the water resource crisis in many arid zones worldwide, from Africa to Asia, affecting millions of people and putting them at risk of hunger. Effective management of arid zone resources, including understanding the risks of toxic trace and heavy elements to humans, coupled with the need to produce more food to feed the world’s growing population, has thus become increasingly important. This very timely book, the only one of its kind on the market, fills the gap of our knowledge of trace elements in these regions. This book begins by introducing the nature and properties of arid zone soil, followed by an updated overview and comprehensive coverage of the major aspects of the trace elements and heavy metals of most concern in the world’s arid and semi-arid soils. These aspects include: - content and distribution - solution chemistry - solid-phase chemistry - selective sequential dissolution techniques - transfer fluxes - bioavailability - pollution and remediation In order to illustrate the themes, a comprehensive and focused case study on transfer fluxes of trace elements in Israeli arid soils is presented. Finally it closes with the global perspectives on anthropogenic interferences in the natural trace elements’ distribution.
Biofuels
In line with the current focus on a sustainable economy, bioethanol and other biofuels have received tremendous attention, making many headlines.
