This thesis presents first successful experiments to carrier-envelope-phase stabilize a high-power mode-locked thin-disk oscillator and to compress the pulses emitted from this laser to durations of only a few-optical cycles. Moreover, the monograph introduces several methods to achieve power-scalability of compression and stabilization techniques. All experimental approaches are compared in detail and may serve as a guideline for developing high-power waveform controlled, few-cycle light sources which offer tremendous potential to exploit extreme nonlinear optical effects at unprecedentedly high repetition rates and to establish table-top infrared light sources with a unique combination of brilliance and bandwidth. As an example, the realization of a multi-Watt, multi-octave spanning, mid-infrared femtosecond source is described. The thesis starts with a basic introduction to the field of ultrafast laser oscillators. It subsequently presents additional details of previously published research results and establishes a connection between them. It therefore addresses both newcomers to, and experts in the field of high-power ultrafast laser development.

This book describes an original improvement in power quality of photovoltaic generation systems obtained by the use of a multilevel inverter implemented with level doubling network (LDN). Modulation principles and harmonic analysis of output voltages are proposed and introduced in detail for both single and three-phase LDN configurations. The analysis is then extended to dc-link current and voltage, with emphasis to low-frequency harmonics and switching frequency ripple. This work represents the first comprehensive implementation of maximum power point tracking (MPPT) schemes using the ripple correlation control (RCC) algorithm in the presence of multiple ripple harmonics, such as in the case of multi level inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors.
The book gathers the chapters of Cognitive InfoCommunication research relevant to a variety of application areas, including data visualization, emotion expression, brain-computer interfaces or speech technologies. It provides an overview of the kind of cognitive capabilities that are being analyzed and developed. Based on this common ground, it may become possible to see new opportunities for synergy among disciplines that were heretofore viewed as being separate. Cognitive InfoCommunication begins by modeling human cognitive states and aptitudes in order to better understand what the user of a system is capable of comprehending and doing. The patterns of exploration and the specific tools that are described can certainly be of interest and of great relevance for all researchers who focus on modeling human states and aptitudes. This innovative research area provides answers to the latest challenges in influence of cognitive states and aptitudes in order to facilitate learning or generally improve performance in certain cognitive tasks such as decision making. Some capabilities are purely human, while others are purely artificial, but in general this distinction is rarely clear-cut. Therefore, when discussing new human cognitive capabilities, the technological background which makes them possible cannot be neglected, and indeed often plays a central role. This book highlights the synergy between various fields that are perfectly fit under the umbrella of CogInfoCom and contribute to understanding and developing new, human-artificial intelligence hybrid capabilities. These, merged capabilities are currently appearing, and the importance of the role they play in everyday life are unique to the cognitive entity generation that is currently growing up.

Nanostructured Semiconductors focuses on the development of semiconductor nanocrystals, their technologies and applications, including energy harvesting, solar cells, solid oxide fuel cells, and chemical sensors. Semiconductor oxides are used in electronics, optics, catalysts, sensors, and other functional devices. In their 2D form, the reduction in size confers exceptional properties, useful for creating faster electronics and more efficient catalysts. Since the first edition of the book, there has been significant progress in the development of new functional nanomaterials with unique and sometimes unpredictable quantum-confined properties within the class what it called two-dimensional (2D) semiconductors. These nanocrystals represent extremely thin nano-structures with thickness of just few nano-meters. Since that time, not only were 2D semiconductor oxides further developed, more importantly, 2D metal dichalcogenides, such as MoS2, MoSe2, WS2, WSe2 and others also progressed significantly in their development demonstrating their superior properties compared to their bulk and microstructural counterparts. The book has been expanded to include these advancements. The book begins with the structure and properties of semiconductor nanocrystals (chapter 1), addresses electronic device applications (chapter 2), discusses 2-Dimensional oxides and dichalcogenide semiconductors (chapters 3 through 5), and ends with energy, environment, and bio applications (chapters 6 through 8).

This text is a hands-on guide to time-frequency transforms for radar imaging and signal analysis. It explores more efficient ways to: extract dispersive scattering features; detect and extract weak signals in noise; form clear radar images; estimate parameters and perform motion compensation; detect and track moving targets in the synthetic aperture radar; and analyze vibration and rotation induced micro-Doppler. This resource introduces an image formation algorithm based on time-frequency-transforms, showing its advantage over the more conventional Fourier-based image formation. Referenced with over 170 equations and 80 illustrations, the book presents algorithms that help improve the result of radar imaging and signal processing. Moreover, the authors discuss future trends in time-frequency to analyze micro-Doppler, and provide a newly developed time-frequency approach to radar signal and image processing to help solve problems associated with conventional approaches.
Since publication of the first edition in 1988 many significant advances have occurred in IC chips that have driven the hybrid packaging processes toward even higher densities and greater performance. The almost exponential increase in density, complexity, and performance of integrated circuits over the past ten years (for example, ASIC (Application Specific Integrated Circuit), VHSIC (Very High Speed IC), VLSIC (Very Large Scale IC), and ULSIC (Ultra Large Scale IC) have driven developments in the interconnect substrates culminating in what is now known as multichip modules (MCM). However, the fundamentals of design, fabrication, and testing of MCMs are essentially the same as for hybrid microcircuit. In the authors' opinion MCMs are extensions of hybrid circuits that can accommodate the new generation of high-speed high-performance chips. In this revised edition they have therefore expanded their treatment of hybrid circuits without finding it necessary to change the fundamentals. They have included a separate chapter on multichip modules and throughout the book have included new and emerging materials and processes that are beginning to be used. Examples include: metal-matrix composites and aluminum nitride as substrate materials, plastic encapsulated microcircuits and chip-on-board as low-cost alternatives to hermetic sealed packages, atmospheric friendly cleaning solvents and methods, and advanced high I/O density quad flat packages (QFP) and ball grid array (BGA) packages. Since the first edition, there have also been tremendous advances in software programs for thermal and electrical analysis and these are also treated in this new edition. The abbreviated Table ofContents below includes the chapter titles and selected sub-headings.

Over the past decade, the Command and Control (C2) field has been making a transformation from top-down, directive command to Network Centric Operations (NCO), peer-to-peer negation, self-synchronization, and agility. As the terms NCO and NEC suggest, C2 systems are regarded as networks, rather than a hierarchy. Accordingly, it is appropriate to view the C2 process and C2 systems through the lens of network theory. Network Topology in Command and Control: Organization, Operation, and Evolution aims to connect the fields of C2 and network science. Featuring timely research on topics pertaining to the C2 network evolution, security, and modelling, this publication is ideal for reference use by students, academicians, and security professionals in the fields of C2 and network science.
This significantly extended second edition addresses the important physical phenomenon of Surface Plasmon Resonance (SPR) or Surface Plasmon Polaritons (SPP) in thin metal films, a phenomenon which is exploited in the design of a large variety of physico-chemical optical sensors. In this treatment, crucial materials aspects for design and optimization of SPR sensors are investigated and described in detail. The text covers a selection of nanometer thin metal films, ranging from free-electron to the platinum-type conductors, along with their combination with a large variety of dielectric substrate materials, and associated individual layer and opto-geometric arrangements. Whereas the first edition treated solely the metal-liquid interface, the SP-resonance conditions considered here are expanded to cover the metal-gas interface in the angular and wavelength interrogation modes, localized and long-range SP's and the influence of native oxidic ad-layers in the case of non-noble metals. Furthermore, a selection of metal grating structures that allow SP excitation is presented, as are features of radiative SP's. Finally, this treatise includes as-yet hardly explored SPR features of selected metal-metal and metal-dielectric superlattices. An in-depth multilayer Fresnel evaluation provides the mathematical tool for this optical analysis, which otherwise relies solely on experimentally determined electro-optical materials parameters. |
