Dissemination of information in communication networks : Broadcasting, gossiping, leader election, and fault-tolerance

Preface Due to the development of hardware technologies (such as VLSI) in the early 1980s, the interest in parallel and distributive computing has been rapidly growingandinthelate1980sthestudyofparallelalgorithmsandarchitectures became one of the main topics in computer science. To bring the topic to educatorsandstudents,severalbooksonparallelcomputingwerewritten. The involvedtextbook“IntroductiontoParallelAlgorithmsandArchitectures”by F. Thomson Leighton in 1992 was one of the milestones in the development of parallel architectures and parallel algorithms. But in the last decade or so the main interest in parallel and distributive computing moved from the design of parallel algorithms and expensive parallel computers to the new distributive reality – the world of interconnected computers that cooperate (often asynchronously) in order to solve di?erent tasks.

Discrete Differential Geometry

Discrete differential geometry is an active mathematical terrain where differential geometry and discrete geometry meet and interact. It provides discrete equivalents of the geometric notions and methods of differential geometry, such as notions of curvature and integrability for polyhedral surfaces. Current progress in this field is to a large extent stimulated by its relevance for computer graphics and mathematical physics. This collection of essays, which documents the main lectures of the 2004 Oberwolfach Seminar on the topic, as well as a number of additional contributions by key participants, gives a lively, multi-facetted introduction to this emerging field.

Dioxygen Binding and Sensing Proteins : A Tribute to Beatrice and Jonathan Wittenberg

Following their own brilliant careers in haeme protein research, the outstanding scientists Jonathan and Beatrice Wittenberg continue to provide inspiration to the research community in the study of oxygen-binding proteins. Their research has provided the intellectual stimulus to bring together scientists from all over the world with the common goal of developing fascinating new ideas and performing innovative experiments.This book is dedicated to Jonathan’s and Bea’s lifetime careers. It further illuminates the facts and ideas which dot the paths they traced in Biochemistry and Physiology, elaborating on how these landmark achievements were made and how the haeme proteins community still refers to them. With the field of haeme protein science such a flourishing area, the contributors to this book predict Jonathan and Bea, having played such a seminal role, will continue to be key figures for quite some time to come.

Dilute III-V Nitride Semiconductors and Material Systems : Physics and Technology

A major current challenge for semiconductor devices is to develop materials for the next generation of optical communication systems and solar power conversion applications. Recently, extensive research has revealed that an introduction of only a few percentages of nitrogen into III-V semiconductor lattice leads to a dramatic reduction of the band gap. This discovery has opened the possibility of using these material systems for applications ranging from lasers to solar cells. Physics and Technology of Dilute III-V Nitride Semiconductors & Novel Dilute Nitride Material Systems reviews the current status of research and development in dilute III-V nitrides, with 24 chapters from prominent research groups covering recent progress in growth techniques, experimental characterization of band structure, defects carrier transport, transport properties, dynamic behavior of N atoms, device applications, modeling of device design, novel optoelectronic integrated circuits, and novel nitrogen containing III-V materials.

Diagrammatology : An investigation on the borderlines of phenomenology, ontology, and semiotics

Diagrammatology investigates the role of diagrams for thought and knowledge. Based on the general doctrine of diagrams in Charles Peirce's mature work, Diagrammatology claims diagrams to constitute a centerpiece of epistemology. The book reflects Peirce's work on the issue in Husserl's contemporanous doctrine of "categorial intuition" and charts the many unnoticed similarities between Peircean semiotics and early Husserlian phenomenology. Diagrams, on a Peircean account, allow for observation and experimentation with ideal structures and objects and thus furnish the access to the synthetic a priori of the regional and formal ontology of the Husserlian tradition.

Development and characterization of a dispersion-encoded method for low-coherence interferometry

This book discusses an extension to low-coherence interferometry by dispersion-encoding. The approach is theoretically designed and implemented for applications such as surface profilometry, polymeric cross-linking estimation and the determination of thin-film layer thicknesses. During a characterization, it was shown that an axial measurement range of 79.91 µm with an axial resolution of 0.1 nm is achievable. Simultaneously, profiles of up to 1.5 mm in length were obtained in a scan-free manner. This marked a significant improvement in relation to the state-of-the-art in terms of dynamic range.

Developing Organogel of CoEnzyme Q10

Coenzyme Q10 is a small lipophilic molecule composed of a benzoquinone ring and a hydrophobic isoprenoid tail and is present in all cell membranes. It is also an antioxidant. It plays a substantial role in energy production by acting as a mobile electron carrier in the electron transport chain. It has poor intestinal absorption and is prepared in topical forms. Organogel is a non-crystalline, non-glassy thermoreversible (thermoplastic) solid material and viscoelastic system can be regarded as a semi-solid preparation which has an immobilized external apolar phase, it is compatible with high molecular weight ingredients. The objective of present work is to prepare new dosage form with studying of different factors and conditions affecting preparation. Materials and methods: stearic acid and Flaxseed oil organogel was prepared by three methods and confirmed by quality assessment methods including: transparency, structure analysis, inverted tube test, kinetic of organogalation and stability test.

Desertification in the Mediterranean Region : A security issue ; Proceedings of the NATO Mediterranean Dialogue Workshop, held in Valencia, Spain, 2-5 December 2003

This book focuses on two basic concepts: security and desertification in the Mediterranean Region and their linkages. Desertification is recognized as a process of land degradation in arid, semi-arid, and dry sub-humid areas of the world that is the result of natural phenomena (e.g. climate variation) and anthropogenic factors. The outcome of this type of degradation has typically been considered to be either a reduction or a loss of both biological and economic productivity. The scope of the book includes the identification of the physical processes of desertification specific to both the north and south Mediterranean Region. Additionally, it specifically questions how changing environmental conditions may potentially reduce stability and peace in the world and thus affect "environmental security."

Defects in High-k Gate Dielectric Stacks : Nano-Electronic Semiconductor Devices

One of the key obstacles to high-k integration into Si nano-technology are the electronic defects in high-k materials. It has been established that defects do exist in high-k dielectrics and they play an important role in device operation. However, very little is known about the nature of the defects or about possible techniques to eliminate, or at least minimize them. Given the absence of a feasible alternative in the near future, well-focused scientific research and aggressive development programs on high-k gate dielectrics and related devices must continue for semiconductor electronics to remain a competitive income producing force in the global market.
