Large Turbo-Generators: Malfunctions and Symptoms
by Isidor Kerszenbaum Geoff KlempnerThis book presents a comprehensive, ordered relationship between malfunctions and symptoms occurring in large turbogenerators. With this book, the operator and/or engineer in a generating station could identify underlying causes of a developing component degradation or a failure quicker, which could potentially save both time and money and reduce the trial-and-error troubleshooting process. Large turbogenerators are the most important source of electricity. They can be found in thousands of power stations in every country. Forced outages, failures and degradation of these very expensive machines have an enormous aggregate cost to society. As such, any tool that can ameliorate loss of production by shaving time from troubleshooting activities, and avoiding unnecessary costs by detecting and promptly responding to component degradation, represents a step forward.

Laser Cooling: Fundamental Properties and Applications
by Galina NemovaIn the recent decades, laser cooling or optical refrigeration—a physical process by which a system loses its thermal energy as a result of interaction with laser light—has garnered a great deal of scientific interest due to the importance of its applications. Optical solid-state coolers are one such application. They are free from liquids as well as moving parts that generate vibrations and introduce noise to sensors and other devices. They are based on reliable laser diode pump systems. Laser cooling can also be used to mitigate heat generation in high-power lasers. This book compiles and details cutting-edge research in laser cooling done by various scientific teams all over the world that are currently revolutionizing optical refrigerating technology. It includes recent results on laser cooling by redistribution of radiation in dense gas mixtures, three conceptually different approaches to laser cooling of solids such as cooling with anti-Stokes fluorescence, Brillouin cooling, and Raman cooling. It also discusses crystal growth and glass production for laser cooling applications. This book will appeal to anyone involved in laser physics, solid-state physics, low-temperature physics or cryogenics, materials research, development of temperature sensors, or infrared detectors.

Laser Filamentation: Mathematical Methods and Models (CRM Series in Mathematical Physics)
by Andre D. Bandrauk Emmanuel Lorin Jerome V. MoloneyThis book is focused on the nonlinear theoretical and mathematical problems associated with ultrafast intense laser pulse propagation in gases and in particular, in air. With the aim of understanding the physics of filamentation in gases, solids, the atmosphere, and even biological tissue, specialists in nonlinear optics and filamentation from both physics and mathematics attempt to rigorously derive and analyze relevant non-perturbative models. Modern laser technology allows the generation of ultrafast (few cycle) laser pulses, with intensities exceeding the internal electric field in atoms and molecules (E=5x109 V/cm or intensity I = 3.5 x 1016 Watts/cm2 ). The interaction of such pulses with atoms and molecules leads to new, highly nonlinear nonperturbative regimes, where new physical phenomena, such as High Harmonic Generation (HHG), occur, and from which the shortest (attosecond - the natural time scale of the electron) pulses have been created. One of the major experimental discoveries in this nonlinear nonperturbative regime, Laser Pulse Filamentation, was observed by Mourou and Braun in 1995, as the propagation of pulses over large distances with narrow and intense cones. This observation has led to intensive investigation in physics and applied mathematics of new effects such as self-transformation of these pulses into white light, intensity clamping, and multiple filamentation, as well as to potential applications to wave guide writing, atmospheric remote sensing, lightning guiding, and military long-range weapons.The increasing power of high performance computers and the mathematical modelling and simulation of photonic systems has enabled many new areas of research. With contributions by theorists and mathematicians, supplemented by active experimentalists who are experts in the field of nonlinear laser molecule interaction and propagation, Laser Filamentation sheds new light on scientific and industrial applications of modern lasers.

Laser-Generated Functional Nanoparticle Bioconjugates: Design for Application in Biomedical Science and Reproductive Biology
by Annette BarchanskiAnnette Barchanski deals with the question how to design nanoparticles for biomedical research. She considers properties such as size, charge, biocompatibility, and functionalization of nanoparticles from a biologist’s point of view in order to achieve specific cellular responses. The author discusses the structure-function relationship of nanoparticle conjugates derived from a laser-based fabrication method. Both the limits and perspectives of tunable conjugate functions are presented, providing a general outline for researchers to configure functionalized nanoparticles with a specifically optimized design for biomedical requests, e.g. in biomedical engineering regenerative science and reproductive biology.
Lasso-MPC – Predictive Control with ℓ1-Regularised Least Squares (Springer Theses)
by Marco GallieriThis thesis proposes a novel Model Predictive Control (MPC) strategy, which modifies the usual MPC cost function in order to achieve a desirable sparse actuation. It features an ℓ1-regularised least squares loss function, in which the control error variance competes with the sum of input channels magnitude (or slew rate) over the whole horizon length. While standard control techniques lead to continuous movements of all actuators, this approach enables a selected subset of actuators to be used, the others being brought into play in exceptional circumstances. The same approach can also be used to obtain asynchronous actuator interventions, so that control actions are only taken in response to large disturbances. This thesis presents a straightforward and systematic approach to achieving these practical properties, which are ignored by mainstream control theory.

Lattices of Dielectric Resonators (Springer Series in Advanced Microelectronics #53)
by Alexander TrubinThis book provides the analytical theory of complex systems composed of a large number of high-Q dielectric resonators. Spherical and cylindrical dielectric resonators with inferior and also whispering gallery oscillations allocated in various lattices are considered. A new approach to S-matrix parameter calculations based on perturbation theory of Maxwell equations, developed for a number of high-Q dielectric bodies, is introduced. All physical relationships are obtained in analytical form and are suitable for further computations. Essential attention is given to a new unified formalism of the description of scattering processes. The general scattering task for coupled eigen oscillations of the whole system of dielectric resonators is described. The equations for the expansion coefficients are explained in an applicable way. The temporal Green functions for the dielectric resonator are presented. The scattering process of short pulses in dielectric filter structures, dielectric antennas and lattices of dielectric resonators is discussed.
Layout Techniques in MOSFETs (Synthesis Lectures on Emerging Engineering Technologies)
by Salvador Pinillos GimenezThis book aims at describing in detail the different layout techniques for remarkably boosting the electrical performance and the ionizing radiation tolerance of planar Metal-Oxide-Semiconductor (MOS) Field Effect Transistors (MOSFETs) without adding any costs to the current planar Complementary MOS (CMOS) integrated circuits (ICs) manufacturing processes. These innovative layout styles are based on pn junctions engineering between the drain/source and channel regions or simply MOSFET gate layout change. These interesting layout structures are capable of incorporating new effects in the MOSFET structures, such as the Longitudinal Corner Effect (LCE), the Parallel connection of MOSFETs with Different Channel Lengths Effect (PAMDLE), the Deactivation of the Parallel MOSFETs in the Bird's Beak Regions (DEPAMBBRE), and the Drain Leakage Current Reduction Effect (DLECRE), which are still seldom explored by the semiconductor and CMOS ICs industries. Several three-dimensional (3D) numerical simulations and experimental works are referenced in this book to show how these layout techniques can help the designers to reach the analog and digital CMOS ICs specifications with no additional cost. Furthermore, the electrical performance and ionizing radiation robustness of the analog and digital CMOS ICs can significantly be increased by using this gate layout approach.

Learning Analytics in R with SNA, LSA, and MPIA
by Fridolin WildThis book introduces Meaningful Purposive Interaction Analysis (MPIA) theory, which combines social network analysis (SNA) with latent semantic analysis (LSA) to help create and analyse a meaningful learning landscape from the digital traces left by a learning community in the co-construction of knowledge. The hybrid algorithm is implemented in the statistical programming language and environment R, introducing packages which capture – through matrix algebra – elements of learners’ work with more knowledgeable others and resourceful content artefacts. The book provides comprehensive package-by-package application examples, and code samples that guide the reader through the MPIA model to show how the MPIA landscape can be constructed and the learner’s journey mapped and analysed. This building block application will allow the reader to progress to using and building analytics to guide students and support decision-making in learning.
