Scientists and engineers in academic and industrial research experience a strong evolving discipline: Computational Materials Science. This discipline provides materials insights that are not readily achievable by experiments, and it offers the opportunity to design materials and composites ?ab-initio?.
This book presents the methods and the practical use of Computational Materials Science using two distinct examples: the development of optimized or alternative materials for CIGS (Copper-Indium-Gallium-di-Selenide) photovoltaics and the optimization of CIGS thin film solar cells for maximum efficiency.
After a general introduction the theoretical background of the book is illustrated:
The strategies and principles of High Performance Computing (HPC) for materials science are covered and rounded out by a number of examples for highly parallel computing.
Next theory and working principles of solar cells are depicted with emphasis on CIGS.
Finally the theory of the quantum mechanical simulations (Density Functional Theory, Monte Carlo simulations for canonical and grand-canonical ensembles, cluster expansions) and the software used for these purposes are presented.
In the practical section of the book the simulation work for the various functional layers of the CIGS cell is described in detail:
After general electronic structure calculations for the CIGS photo absorber light is shed on the role of the Indium/Gallium distribution as well as on the influence of vacancies in chalcopyrite structures.
Base requirements for the buffer layer are defined and simulation results from a search for alternative (Cadmium-free) buffer compounds are presented. Experimental results for synthesized replacement materials complete this part of the work.
The optimization of the system transparent conductive oxide (TCO) / contact grid for maximum overall cell efficiency is described. The charge transport through TCO/grid is modelled by a Finite Element Method and cell efficiencies are calculated considering ohmic as well as optical losses.
The last section of the book outlines the simulation results implications on the optimization of thin film cell processing. Special emphasis is placed on the influence of process temperatures on film homogeneity and cell efficiency as well as on the requirements for substrate selection. The calculations are validated by experimental results.
The Handbook of Computational Neurodegeneration provides a comprehensive overview of the field and thus bridges the gap between standard textbooks of research on neurodegeneration and dispersed publications for specialists that have a narrowed focus on computational methods to study this complicated process.
The handbook reviews the central issues and methodological approaches related to the field for which the reader pursues a thorough overview. It also conveys more advanced knowledge, thus serving both as an introductory text and as a starting point for an in-depth study of a specific area, as well as a quick reference source for the expert by reflecting the state of the art and future prospects. The book includes topics that are usually missing in standard textbooks and that are only marginally represented in the specific literature.
The broad scope of this handbook is reflected by five major parts that facilitate an integration of computational concepts, methods and applications in the study of neurodegeneration. Each part is intended to stand on its own, giving an overview of the topic and the most important problems and approaches, which are supported by examples, practical applications, and proposed methodologies. The basic concepts and knowledge, standard procedures and methods are presented, as well as recent advances and new perspectives.
This book highlights the applications of signal and image processing to acoustical imaging. The book first describes the basic tools involved ? the 2D transform, fast Fourier transform (FFT) and applications, and deconvolution ? before introducing readers to higher order statistics, wavelets, and neural networks. The important topic of digital signal processing is also described, focusing on the example of homomorphic signal processing. The book also details the design of digital filters and array signal processing, before examining applications to image processing in the final section: image enhancement and optimization, image restoration, and image compression.
This three-volume encyclopedia comprises approximately uniform 600 entries.
Computer vision problems are much larger than ever before. One way to satisfy demand is to design more efficient and clever algorithms that optimize computations in an existing processor. Such fast algorithms are becoming increasingly important for tele-reality, interactive media and visual serving applications. This book presents fast and reliable algorithms for dense stereo matching ? for every point on the image ? and optical-flow estimations using a general language, such as C, rather than dedicated hardware implementation.
Techniques described are: fast algorithms for similarity measure, use of subregioning technique to expedite similarity calculation, multiresolution scheme, fast 3-D surface technique for stereo matching, and stereo matching using warping. Fast Algorithms for Stereo Matching is a useful reference for academics, professionals, researchers, practitioners, and advanced graduate students in the areas of computer vision, digital photogrammetry, and 3-D video coding.

This thesis addresses practical data quality and variant detection issues regarding research on next-generation DNA sequencing. It develops for the first time a hidden Markov model (HMM) to describe the error pattern and data generation of next-generation DNA sequencers. Further, it proposes using a haplotype-based method, which employs the HMM and re-alignment to suppress the interference of sequencing errors and incorrect alignments, in order to improve the detection accuracy of SNPs and InDels. Lastly, the thesis sheds new light on the interpretation and application of error modeling for next-generation DNA sequencing.

Zero-knowledge interactive proofs play a central role in the design and study of cryptographic protocols and are rich objects for complexity-theoretic study. Statistical zero-knowledge (SZK) proofs achieve strong information-theoretic security, and can provide a clean test bed for the study of more general notions that incorporate computational security.
This monograph is a revised and extended version of the author's PhD thesis, the winning thesis of the 2000 ACM Doctoral Dissertation Competition. It is a comprehensive investigation of statistical zero-knowledge (SZK) proofs. It begins by showing that SZK has two natural complete problems, and then uses these complete problems to address a wide variety of fundamental questions about SZK. It also includes a chapter that surveys recent developments in the area, in particular how the results and techniques of this thesis have been extended to computational zero-knowledge proofs and arguments.
The presentation offers clarity and intuition, assuming only a basic background in computational complexity and cryptography, and thus the book can bring a graduate student or a researcher in a related area up to date on this topic. At the same time, it includes clear statements of numerous open problems and research directions, which are likely to interest experts in the area.
A memristor is a two-terminal device whose resistance depends on one or more internal state variables of the device and it is defined by a state-dependent Ohm's law. Its resistance depends on the entire past signal waveform of the applied voltage, or current, across the memristor. Using memristors one can achieve circuit functionalities that are not possible to establish with resistors, capacitors and inductors, therefore the memristor is of great pragmatic usefulness.Potential unique applications of memristors are in spintronic devices, ultra-dense information storage, neuromorphic circuits, and programmable electronics. This handbook focuses on design, fabrication, modelling of and implementation of computation in spatially extended discrete media with many memristors. The World's authorities in computer science, mathematics, electronics, physics and computer engineering present:
- foundations of the memristor theory and applications
- demonstrate how to design neuromorphic network architectures based on memristor assemblies
- analysis varieties of the dynamic behaviour of memristive networks
- show how to realise computing devices from memristors
The Handbook of Memristor Networks is a unique self-contained compendium of results on memristor research developed by top world experts in the field. All aspects of memristor networks are presented in detail, in a fully accessible, often tutorial like style. The book is an indispensable source of information and an inspiring reference text for future generations of computer scientists, mathematicians, physicists and engineers.

This book is an introduction to relevant aspects of the foraging literature for algorithmic design, and an overview of key families of optimization algorithms that stem from a foraging metaphor. The authors first offer perspectives on foraging and foraging-inspired algorithms for optimization, they then explain the techniques inspired by the behaviors of vertebrates, invertebrates, and non-neuronal organisms, and they then discusses algorithms based on formal models of foraging, how to evolve a foraging strategy, and likely future developments.
No prior knowledge of natural computing is assumed. This book will be of particular interest to graduate students, academics and practitioners in computer science, informatics, data science, management science, and other application domains.
