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 Jasjit S. Suri Ayman El-BazLevel 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.

Levels of Organization in the Biological Sciences (Vienna Series in Theoretical Biology)
by Daniel S. Brooks, James DiFrisco, and William C. WimsattScientific philosophers examine the nature and significance of levels of organization, a core structural principle in the biological sciences.This volume examines the idea of levels of organization as a distinct object of investigation, considering its merits as a core organizational principle for the scientific image of the natural world. It approaches levels of organization--roughly, the idea that the natural world is segregated into part-whole relationships of increasing spatiotemporal scale and complexity--in terms of its roles in scientific reasoning as a dynamic, open-ended idea capable of performing multiple overlapping functions in distinct empirical settings.The contributors--scientific philosophers with longstanding ties to the biological sciences--discuss topics including the philosophical and scientific contexts for an inquiry into levels; whether the concept can actually deliver on its organizational promises; the role of levels in the development and evolution of complex systems; conditional independence and downward causation; and the extension of the concept into the sociocultural realm. Taken together, the contributions embrace the diverse usages of the term as aspects of the big picture of levels of organization.ContributorsJan Baedke, Robert W. Batterman, Daniel S.

Leveraging Blockchain Technology: Governance, Risk, Compliance, Security, and Benevolent Use Cases (Security, Audit and Leadership Series)
by Shaun AghiliBlockchain technology is a digital ledger system that allows for secure, transparent and tamper-proof transactions. It is essentially an often decentralized, distributed, peer-to-peer database that is maintained by a network of computers instead of a single entity, making it highly resistant to hacking and data breaches. By providing greater security, transparency and efficiency, blockchain technology can help to create a more equitable and sustainable world.Blockchain technology has the potential to help mankind in various ways, some of which include but are not limited to: Decentralization and Transparency: Blockchain technology allows for decentralization of data and transactions, making them more transparent and accountable. This is particularly important in fields such as finance, where trust and transparency are critical. Increased Security: Blockchain technology is inherently secure due to its distributed nature, making it very difficult for hackers to compromise the system. This makes it an ideal solution for data and information storage, particularly in areas such as health and finance, where privacy and security are of utmost importance. Faster Transactions: Blockchain technology eliminates the need for intermediaries, reducing the time and cost associated with transactions. This makes it an ideal solution for international trade, remittances and other types of financial transactions, especially in parts of the world where a great number of individuals do not have access to basic banking services. Immutable Record: One of the fundamental attributes of blockchain is its immutability. Once data is added to the blockchain, it becomes nearly impossible to alter or delete. This feature ensures a tamper-resistant and reliable record of transactions, crucial for maintaining integrity in various industries, including supply chain management and legal documentation. Smart Contracts: Blockchain technology supports the implementation of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. This automation streamlines processes and reduces the risk of fraud, particularly in sectors like real estate and legal agreements. Interoperability: Blockchain’s ability to facilitate interoperability allows different blockchain networks to communicate and share information seamlessly. This attribute is pivotal for creating a unified and interconnected ecosystem, especially as various industries adopt blockchain independently. Interoperability enhances efficiency, reduces redundancy and fosters collaboration across diverse sectors. Leveraging Blockchain Technology: Governance, Risk, Compliance, Security, and Benevolent Use Cases discusses various governance, risk and control (GRC) and operational risk-related considerations in a comprehensive, yet non-technical, way to enable business leaders, managers and professionals to better understand and appreciate its various potential use cases. This book is also a must-read for leaders of non-profit organizations, allowing them to further democratize needs that we often take for granted in developed countries around the globe, such as access to basic telemedicine, identity management and banking services.
Leveraging Digital Tools to Assess Student Learning (Student Assessment for Educators)
by Stephanie Smith BudhaiLeveraging Digital Tools to Assess Student Learning provides a practical approach to using technology to collect, interpret, and curate assessment data in K-12 in-person, online, hybrid, and dual learning environments. Digital media, emerging learning technologies, and handheld devices play larger roles than ever in students’ 21st-century educational experiences. Digital tools, meanwhile, can also transform assessment practices for teachers, allowing more efficient means of identifying gaps and modifying instruction to maximize student learning. Situating assessment practices in today’s networked, flexible, and virtual classrooms, this book reframes polling and quizzing, social media and memes, and multimedia platforms as digital learning tools for engaging, interactive, and meaningful formative, summative, open-ended, peer and self-paced assessments. The final chapter discusses technology’s role in organizing, evaluating, and disseminating assessment data to students, their families, and administrators.
Leveraging Distortions: Explanation, Idealization, and Universality in Science
by Collin RiceAn examination of how scientists deliberately and justifiably use pervasive distortions of relevant features to explain and understand natural phenomena.A fundamental rule of logic is that in order for an argument to provide good reasons for its conclusion, the premises of the argument must be true. In this book, Collin Rice shows how the practice of science repeatedly, pervasively, and deliberately violates this principle. Rice argues that scientists strategically use distortions that misrepresent relevant features of natural phenomena in order to explain and understand--and that they use these distortions deliberately and justifiably in order to discover truths that would be otherwise inaccessible. Countering the standard emphasis on causation, accurate representation, and decomposition of science into its accurate and inaccurate parts, Rice shows that science's epistemic achievements can still be factive despite their being produced through the use of holistically distorted scientific representations. Indeed, he argues, this distortion is one of the most widely employed and fruitful tools used in scientific theorizing. Marshalling a range of case studies, Rice contends that many explanations in science are noncausal, and he presents an alternate view of explanation that captures the variety of noncausal explanations found across the sciences. He proposes an alternative holistic distortion view of idealized models, connecting it to physicists' concept of a universality class; shows how universality classes can overcome some of the challenges of multiscale modeling; and offers accounts of explanation, idealization, modeling, and understanding.

Leviathan
by James Byron HugginsWith the creation of an unholy beast comes the end of the world in this diabolical thriller from the international bestselling author of Crux and Hunter. On an Icelandic Island, an illegal experiment intended to create the perfect biological weapon has transformed a once-innocent creature into the biblical Leviathan that once terrorized the world. Able to shatter steel and granite as easily as it can melt the strongest containment shields, Leviathan escapes from its pen and is loose in a vast underground chamber harboring soldiers and scientists. The installation cannot allow Leviathan to reach the surface. For if Leviathan reaches the world, it could well be the end of the Earth. They must hold the line, here, and destroy it . . . even if they must detonate a last-chance nuclear failsafe built into the chamber itself. But, first, they must fight with every weapon at their disposal to discover if the beast can be killed at all. It is a battle many will not survive. As soldiers and scientists are vaporized by Leviathan&’s hellish flame, or ripped apart by the dragon&’s claws and fangs, a lone electrical engineer is forced to join the fight. And in the midst of what might well be the last battle for Mankind, Connor must find a way—any way—to save his family and kill this powerful, bloodthirsty Beast of Legend that has never been killed before. Before it feasts upon the world.Praise for James Byron Huggins &“Huggins writes like a man possessed.&”—Steve Jackson, New York Times bestselling author &“May be the thriller of the year.&”—BookPage on Cain &“Pure entertainment.&”—Publishers Weekly on Hunter
