Level Doubling Network and Ripple Correlation Control MPPT Algorithm for Grid-Connected Photovoltaic Systems (Springer Theses)
by Manel HammamiThis 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 multilevel inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors.

Level Set Method in Medical Imaging Segmentation
by Ayman El-Baz Jasjit S. SuriLevel set methods are numerical techniques which offer remarkably powerful tools for understanding, analyzing, and computing interface motion in a host of settings. When used for medical imaging analysis and segmentation, the function assigns a label to each pixel or voxel and optimality is defined based on desired imaging properties. This often includes a detection step to extract specific objects via segmentation. This allows for the segmentation and analysis problem to be formulated and solved in a principled way based on well-established mathematical theories. Level set method is a great tool for modeling time varying medical images and enhancement of numerical computations.

Level Set Methods for Fluid-Structure Interaction (Applied Mathematical Sciences #210)
by Georges-Henri Cottet Emmanuel Maitre Thomas MilcentThis monograph is devoted to Eulerian models for fluid-structure interaction by applying the original point of view of level set methods.In the last 15 years, Eulerian models have become popular tools for studying fluid-structure interaction problems. One major advantage compared to more conventional methods such as ALE methods is that they allow the use of a single grid and a single discretization method for the different media. Level set methods in addition provide a general framework to follow the fluid-solid interfaces, to represent the elastic stresses of solids, and to model the contact forces between solids.This book offers a combination of mathematical modeling, aspects of numerical analysis, elementary codes and numerical illustrations, providing the reader with insights into the applications and performance of these models.Assuming background at the level of a Master’s degree, Level Set Methods for Fluid-Structure Interaction provides researchers in the fields of numerical analysis of PDEs, theoretical and computational mechanics with a basic reference on the topic. Its pedagogical style and organization make it particularly suitable for graduate students and young researchers.

Levels of Perception
by Laurence Harris Michael JenkinIn this book the authors relate and discuss the idea that perceptual processes can be considered at many levels. A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level. For example "induced motion" can be analyzed in terms of eye movements or at the retinal level or at a much higher cognitive level: how do these analyses fit together? The concept of levels also makes us think of the flow of information between levels, which leads to a consideration of the roles of top-down and bottom-up (or feed-forward, feed-back) flow. There are sections devoted to vestibular processing, eye movement processing and processing during brightness perception. The final section covers levels of processing in spatial vision. All scientists and graduate students working in vision will be interested in this book as well as people involved in using visual processes in computer animations, display design or the sensory systems of machines.
Levels of Reality in Science and Philosophy: Re-examining the Multi-level Structure of Reality (Jerusalem Studies in Philosophy and History of Science)
by Stavros Ioannidis Gal Vishne Meir Hemmo Orly ShenkerThis book offers a unique perspective on one of the deepest questions about the world we live in: is reality multi-leveled, or can everything be reduced to some fundamental ‘flat’ level? This deep philosophical issue has widespread implications in philosophy, since it is fundamental to how we understand the world and the basic entities in it. Both the notion of ‘levels’ within science and their ontological implications are issues that are underexplored in the philosophical literature. The volume reconsiders the view that reality contains many levels and opens new ways to understand the ontological status of the special sciences. The book focuses on major open questions that arise at the foundations of cognitive science, cognitive psychology, brain science and other special sciences, in particular with respect to the physical foundations of these sciences. For example: Is the mental computational? Do brains compute? How can the special sciences be autonomous from physics, grounded in, or based on, physics and at the same time irreducible to physics? The book is an important read for scientists and philosophers alike. It is of interest to philosophers of science, philosophers of mind and biology interested in the notion of levels, but also to psychologists, cognitive scientists and neuroscientists investigating such issues as the precise relation of the mental to the underlying neural structures and the appropriate approach to study it.
Levels of Selection in Evolution
by Laurent KellerEver since the groundbreaking work of George Williams, W. D. Hamilton, and Richard Dawkins, evolutionary biologists have recognized that natural selection generally does not operate for the good of the group, but rather for the good of lower-level units such as the individual, the cell, even the gene. One of the fundamental problems of biology is: what keeps competition between these various levels of natural selection from destroying the common interests to be gained from cooperation? In this volume twelve prominent scientists explore this question, presenting a comprehensive survey of the current theoretical and empirical research in evolutionary biology. Recent studies show that at many levels of biological organization, mechanisms have evolved to prevent potential conflict in natural selection. Editor Laurent Keller's aim in this book is to bring together leading researchers from all biological disciplines to outline these potential conflicts and discuss how they are resolved. A multi-level approach of this kind allows important insights into the evolution of life, as well as bridging the long-standing conceptual chasm between molecular and organismal biologists. The chapters here follow a rigorous theoretical framework, giving the book an overall synergy that is unique to multi-authored books. The contributors, in addition to the editor, are H. Charles J. Godfray, Edward Allen Herre, Dawn M. Kitchen, Egbert Giles Leigh, Jr., Catherine M. Lessells, Richard E. Michod, Leonard Nunney, Craig Packer, Andrew Pomiankowski, H. Kern Reeve, John Maynard Smith, and Eörs Szathmáry.

Leveraging Mobile Media: Cross-Media Strategy and Innovation Policy for Mobile Media Communication (Information Age Economy)
by Valerie FeldmannMobile communications and next generation wireless networks emerge as new distribution channels for the media. This development offers exciting new opportunities for media companies: the mobile communication system creates new usage contexts for media content and services; the social use of mobile communications suggests that identity representation in social networks, impulsive access to trusted media brands, and micro-coordination emerge as new sources of value creation in the media industries. In the light of this background, this book takes two different viewpoints on the development of mobile media: from a competitive strategy point of view it analyzes the extension of cross-media strategies and the emergence of cross-network strategies; from a public policy point of view it develops demands and requirements for an innovation policy that fosters innovation in mobile media markets.
Leveraging Technology as a Response to the COVID Pandemic: Adapting Diverse Technologies, Workflow, and Processes to Optimize Integrated Clinical Management (Intelligent Health Series)
by Harry P. Pappas Paul H. FrischIn 2019 the world was struck with the Coronavirus (COVID-19) infecting major portions of the world’s population. There were no vaccines or treatments available to help mitigate the disease or offer a cure. The world's health systems were inundated with massive numbers of patients with varying ranges of symptoms, acuity, and levels of criticality. The world's healthcare organizations soon found themselves in an unmanageable situation, directly impacting the ability to manage patients across the entire healthcare environment. Most healthcare institutions had plans for emergency preparedness and procedures to deal with temporary crises, none of which were effective against the impact of COVID-19. COVID-19 was a highly contagious disease, resulting in high volumes of admissions with long lengths of stay. The virus quickly overwhelmed institutions with large patient volumes, resulting in shortages of patient beds, medical equipment, personal protective devices, cleaning agents, and other critical supplies. Hospital operations were further impacted by staff shortages due to exposure, resulting contagion, the shutdown of transit systems, and responsibilities at home due to school and business closures. This timely and important book describes the impact on the hospital ability to provide patient care and how healthcare institutions leveraged diverse technology solutions to combat the impact of COVID-19 on providing patient care. The authors also discuss implementation of these technology solutions and the many lessons learned of how healthcare institutions can enhance their emergency preparedness in the future from the COVID experience. The authors would like to acknowledge, thank, and dedicate this book to the hundreds of thousands of healthcare workers around the world who spent countless hours and put their own lives and families lives at risk to help patients though this pandemic.
