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.
Digital watermarking ; Vol. 3304 ; 3rd International Workshop, IWDW 2004, Seoul, Korea, October 30 - November 1, 2004, revised selected papers
We are happy to present to you the proceedings of the 3rd International Workshop on Digital Watermarking, IWDW 2004. Since its modern reappearance in the academic community in the early 1990s, great progress has been made in understanding both the capabilities and the weaknesses of digital watermarking. On the theoretical side, we all are now well aware of the fact that digital watermarking is best viewed as a form of communication using side information. In the case of digital watermarking the side information in question is the document to be watermarked. This insight has led to a better understanding of the limits of the capacity and robustness of digital watermarking algorithms. It has also led to new and improved watermarking algorithms, both in terms of capacity and imperceptibility. Similarly, the role of human perception, and models thereof, has been greatly enhanced in the study and design of digital watermarking algorithms and systems. On the practical side, applications of watermarking are not yet abundant. The original euphoria on the role of digital watermarking in copy protection and copyright protection has not resulted in widespread use in practical systems. With hindsight, a number of reasons can be given for this lack of practical applications.

Developmental Biology of Neoplastic Growth
In this book, tumour growth is perceived as a deviation from the normal development of the human organism. The molecular, cellular, and tissue determinants of different tumours are discussed showing that each is a different disease, often corresponding to a particular developmental stage. The natural history of several cancers illustrates how clinical incidence can be just the visible part of the iceberg, while the first changes at the tissue level sometimes occur several years before tumour growth becomes manifest.
Detection and Disposal of Improvised Explosives
It including: Methods of detection of Improvised Explosives (IE). Methods of detection of Improvised explosives devices (IED). Disposal and safe handling of ID and IED. The treatment of detection methods may be divided in the following groups: Overview about the different methods; Trace- and vapor detection; Electromagnetic methods; Neutron methods; Laser techniques. Because of different definitions of Improvised Explosives the parti- pants of the workshop agreed after some discussions with the following definition: An Improvised Explosive (IE) can be any chemical compound or mixture capable of an explosive reaction. They are normally easily prepared by a knowledgeable layman under simple conditions. Components of IE are typically inorganic salts containing molecular bound oxygen like nitrates, chlorates or perchlorates etc. or organic compounds with nitro-, nitami- or nitrate-groups or peroxides. Admixtures of military or commercial explosive materials are also used. From the chemical point of view IE can be divided into the following types: Salts containing chemical groups with oxygen (like nitrates, chlorates or perchlorates etc.) in mixtures with combustible substances like carbon-hydrogen compounds.

Design and Analysis of Simulation Experiments
This is an advanced expository book on statistical methods for the Design and Analysis of Simulation Experiments (DASE). Though the book focuses on DASE for discrete-event simulation (such as queuing and inventory simulations), it also discusses DASE for deterministic simulation (such as engineering and physics simulations). The text presents both classic and modern statistical designs. Classic designs (e.g., fractional factorials) assume only a few factors with a few values per factor. The resulting input/output data of the simulation experiment are analyzed through low-order polynomials, which are linear regression (meta)models. Modern designs allow many more factors, possible with many values per factor. These designs include group screening (e.g., Sequential Bifurcation, SB) and space filling designs (e.g., Latin Hypercube Sampling, LHS). The data resulting from these modern designs may be analyzed through low-order polynomials for group screening and various metamodel types (e.g., Kriging) for LHS.

Deep neural networks and data for automated driving : robustness, uncertainty quantification, and insights towards safety
Environment perception for highly automated driving heavily employs deep neural networks, facing many challenges. How much data do we need for training and testing? How to use synthetic data to save labeling costs for training? How do we increase robustness and decrease memory usage? For inevitably poor conditions: How do we know that the network is uncertain about its decisions? Can we understand a bit more about what actually happens inside neural networks? This leads to a very practical problem particularly for DNNs employed in automated driving: What are useful validation techniques and how about safety? This book unites the views from both academia and industry, where computer vision and machine learning meet environment perception for highly automated driving. Naturally, aspects of data, robustness, uncertainty quantification, and, last but not least, safety are at the core of it. This book is unique: In its first part, an extended survey of all the relevant aspects is provided. The second part contains the detailed technical elaboration of the various questions mentioned above.
Decentralisation and Privatisation in Education : The Role of the State
The book examines the overall interplay between privatisation, decentralisation and the role of the state. The authors draw upon recent studies in the areas of decentralisation, privatisation and the role of the state in education. By referring to Bourdieu’s call for critical policy analysts to engage in a ‘critical sociology’ of their own contexts of practice, and poststructuralist and postmodernist pedagogy, this collection of book chapters demonstrate how central discourses surrounding the debate of privatisation, decentralisation and the role of the state are formed in the contexts of dominant ideology, power, and culturally and historically derived perceptions and practices.
Data mining with computational intelligence

Cryocoolers 13
The last two years have witnessed a continuation in the breakthrough shift toward pulse tube cryocoolers for long-life, high-reliability cryocooler applications. New this year are papers de scribing the development of very large pulse tube cryocoolers to provide up to 1500 watts of cooling for industrial applications such as cooling the superconducting magnets of Mag-lev trains, coolmg superconducting cables for the power mdustry, and liquefymg natural gas. Pulse tube coolers can be driven by several competing compressor technologies. One class of pulse tube coolers is referred to as "Stirling type" because they are based on the linear Oxford Stirling-cooler type compressor; these generally provide coolmg m the 30 to 100 K temperature range and operate ^t frequencies from 30 to 60 Hz. A second type of pulse tube cooler is the so-called "Gifford-McMahon type. " Pulse tube coolers of this type use a G-M type compressor and lower frequency operation (~1 Hz) to achieve temperatures in the 2 to 10 K temperature range. The third type of pulse tube cooler is driven by a thermoacoustic oscillator, a heat engine that functions well in remote environments where electricity is not readily available. All three types are described, and in total, nearly half of this proceedings covers new developments in the pulse tube arena. Complementing the work on low-temperature pulse tube and Gifford-McMahon cryocoolers is substantial continued progress on rare earth regenerator materials.
Critical Success Factors of Offshore Software Develpment Projects : The Perspective of German-Speaking Companies
In an effort to cut costs and re-focus on their core competences, The author develops a model that comprises 29 critical success factors which are classified into four distinct groups: internal suitability, internal management, external suitability, and external management factors. With regard to the developed model, both the implementation of an online survey and the conduction of two in-depth case studies show that the external management factors are particularly relevant for the successful implementation of an offshore software development project and that the perception of the individual critical success factors greatly depends on the company perspective.
Creativity, Psychology and the History of Science
The present book includes papers from a wide range of topics. In the contributions to creativity research, Gruber proposes his key ideas for studying creative work. Gruber focuses on how the thinking, motivation and affect of extraordinarily creative individuals evolve and how they interact over long periods of time. Gruber’s approach bridges many disciplines and subdisciplines in psychology and beyond, several of which are represented in the present volume: cognitive psychology, developmental psychology, history of science, aesthetics, and politics. The volume thus presents a unique and comprehensive contribution to our understanding of the creative process. Many of Gruber's papers have not previously been easily accessible; they are presented here in thoroughly revised form. The book is for psychologists, historians and philosophers of science interested in the intersection of psychology and the history of science.
Creating the European Area of Higher Education : Voices from the Periphery
This volume brings together a group of higher education researchers across Europe and looks into the implementation of the Bologna Process in the countries often attributed a peripheral status. Although it is also obvious that if the Process has a center, it stands external to higher education systems and universities it concerns. One can possibly find it either in Brussels or across the Atlantic in the United States, internationally perceived as the main competitor to European higher education. In addition to cultural and political issues the European higher education project faces in various countries, the volume pays particular attention to the role of students as well as the changing position of the intellectuals under its impact.
