Understanding Spectrum Liberalisation

Understanding Spectrum Liberalisation

Until the 1990s almost all spectrum licenses were given away practically for free—even the first mobile licenses which laid the foundation for multi-billion dollar companies that dominate stock markets around the world. In the past fifteen years there has been a concerted attempt to liberalise the sector and make it more open to market forces. This book examines this attempt. Exploring the new frontier for spectrum policy Understanding Spectrum Liberalisation identifies the successes and failures of the main policy initiatives of the past decade. It explains in layman’s terms the technical and policy background needed to understand these debates. For those already working in the field the book provides a lively analysis of recent policy initiatives along with an authoritative interpretation of the latest developments in spectrum policy. It examines individual liberalisation initiatives in detail and explains the logic behind moves towards spectrum sharing which is seen as the next policy phase. This book will help non-specialists climb the formidable learning curve quickly. It is ideal for those who have just become involved in the spectrum field whether in industry government or as a regulator as well as those with expertise in one area of spectrum management who want to learn more about the other areas. History is about the concerns of the present so the saying goes and the authors hope that their interpretation of the very recent past will stimulate debate about future policy and help you make substantive contributions to ongoing policy debates.

Flavonoids and Anti-Aging The Role of Transcription Factor Nuclear Erythroid 2-Related Factor2

Flavonoids and Anti-Aging The Role of Transcription Factor Nuclear Erythroid 2-Related Factor2

The nuclear factor erythroid 2-related factor 2 (Nrf2) was described as a master regulator of the cellular antioxidant response. Moreover many critical biological functions linked to cell viability metabolism autophagy inflammation immunity and differentiation have been attributed to Nrf2 which regulates over 600 genes. It is well known that oxidative stress which Nrf2 can ameliorate plays a key role in many pathologic processes such as aging obesity diabetes cancer and neurodegenerative diseases. Flavonoids on the other hand through their ability to activate and upregulate Nrf2 can have anti-oxidative anti-inflammatory anti-mutagenic and anti-carcinogenic properties. Flavonoids are an essential ingredient in nutraceuticals functional foods and pharmaceuticals. The present book Flavonoids and Anti-Aging: The Role of Transcription Factor Nuclear Erythroid 2-Related Factor2 focuses on the interaction between Nrf2 and flavonoids and their applications in various conditions such as aging osteoporosis cardiovascular diseases and neurodegenerative disease and many other areas. Key Features: Focuses on the mechanisms and use of flavonoids in activating Nrf2 as an anti-aging and WELLNESS molecule Provides a specific approach to flavonoid activation of Nrf2 and its implications in aging and various disease conditions and its applications as nutraceuticals Presents flavonoid-based functional foods Discusses the flavonoid nutraceuticals market and future trends Written by experts in the field this book provides a unique approach to understanding the flavonoid activation of the transcription factor Nrf2 which is responsible for many different disease conditions due to increased reactive oxidative species in the body caused by some physiological triggers. | Flavonoids and Anti-Aging The Role of Transcription Factor Nuclear Erythroid 2-Related Factor2

Modern Optimization Methods for Decision Making Under Risk and Uncertainty

Modern Optimization Methods for Decision Making Under Risk and Uncertainty

The book comprises original articles on topical issues of risk theory rational decision making statistical decisions and control of stochastic systems. The articles are the outcome of a series international projects involving the leading scholars in the field of modern stochastic optimization and decision making. The structure of stochastic optimization solvers is described. The solvers in general implement stochastic quasi-gradient methods for optimization and identification of complex nonlinear models. These models constitute an important methodology for finding optimal decisions under risk and uncertainty. While a large part of current approaches towards optimization under uncertainty stems from linear programming (LP) and often results in large LPs of special structure stochastic quasi-gradient methods confront nonlinearities directly without need of linearization. This makes them an appropriate tool for solving complex nonlinear problems concurrent optimization and simulation models and equilibrium situations of different types for instance Nash or Stackelberg equilibrium situations. The solver finds the equilibrium solution when the optimization model describes the system with several actors. The solver is parallelizable performing several simulation threads in parallel. It is capable of solving stochastic optimization problems finding stochastic Nash equilibria and of composite stochastic bilevel problems where each level may require the solution of stochastic optimization problem or finding Nash equilibrium. Several complex examples with applications to water resources management energy markets pricing of services on social networks are provided. In the case of power system regulator makes decision on the final expansion plan considering the strategic behavior of regulated companies and coordinating the interests of different economic entities. Such a plan can be an equilibrium − a planned decision where a company cannot increase its expected gain unilaterally. | Modern Optimization Methods for Decision Making Under Risk and Uncertainty

Forensic Gait Analysis Principles and Practice

Forensic Gait Analysis Principles and Practice

Gait analysis is the systematic study of human walking using the eye and brain of experienced observers augmented by instrumentation for measuring body movements body mechanics and the activity of the muscles. Since Aristotle’s work on gait analysis more than 2000 years ago it has become an established clinical science used extensively in the healthcare and rehabilitation fields for diagnosis and treatment. Forensic Gait Analysis details the more recent and rapidly developing use of gait analysis in the forensic sciences. The book considers the use of observational gait analysis based on video recordings to assist in the process of identification or exclusion. With the increase in use of CCTV and surveillance systems over the last 20 to 30 years there has been a steady and rapid increase in the use of gait as evidence. Currently gait analysis is widely used in the UK in criminal investigations with increasing awareness of its potential use in the US Europe and globally. The book details the history of the science current practices and of the emergent application to establish best-practice standards that conform to those of other forensic science disciplines. Engagement with the Forensic Science Regulator and the Chartered Society of Forensic Sciences in the UK and the International Association for Identification has helped to ensure and enhance the quality assurance of forensic gait analysis. However there remains a fundamental lack of standardized training and methodology for use in evidentiary and investigative casework. This book fills that void serving as one of the first to describe the current state of practice capabilities and limitations and to outline methods standards of practice and expectations of the gait analyst as a forensic practitioner. Forensic Gait Analysis reflects current research and forensic practice and will serve as a state-of-the-art guide to the use of gait analysis in the forensic context—for both education and training purposes. It will be a welcome addition to the libraries of professionals in the areas of podiatry gait analysis forensic video analysis law enforcement and legal practice. | Forensic Gait Analysis Principles and Practice
