This book focuses on how machine learning techniques can be used to analyze and make use of one particular category of behavioral biometrics known as the gait biometric. A comprehensive Ground Reaction Force (GRF)-based Gait Biometrics Recognition framework is proposed and validated by experiments. In addition, an in-depth analysis of existing recognition techniques that are best suited for performing footstep GRF-based person recognition is also proposed, as well as a comparison of feature extractors, normalizers, and classifiers configurations that were never directly compared with one another in any previous GRF recognition research. Finally, a detailed theoretical overview of many existing machine learning techniques is presented, leading to a proposal of two novel data processing techniques developed specifically for the purpose of gait biometric recognition using GRF. This book · introduces novel machine-learning-based temporal normalization techniques · bridges research gaps concerning the effect of footwear and stepping speed on footstep GRF-based person recognition · provides detailed discussions of key research challenges and open research issues in gait biometrics recognition · compares biometrics systems trained and tested with the same footwear against those trained and tested with different footwear

In this book, Justin DePlato examines and analyzes the reasons and justifications for, as well as instances of, executive emergency power in political thought and action. The book begins by analyzing the theory of executive emergency power across a wide breadth of philosophical history, from Ancient Greek, Renaissance, through modern American political thought. This analysis indicates that in political philosophy two models exist for determining and using executive emergency power: an unfettered executive prerogative or a constitutional dictatorship. The modern American approach to executive emergency power is an unfettered executive prerogative, whereby the executive determines what emergency power is and how to use it. The book addresses the fundamental question of whether executive power in times of crisis may be unfettered and discretionary or rather does the law define and restrain executive emergency power. The author reviews and analyzes seven U.S. presidencies that handled a domestic crisis—Washington, Jefferson, Madison, Jackson, Lincoln, G. W. Bush, and Obama—to show that presidents become extraordinarily powerful during crises and act unilaterally without oversight. The use of executive emergency power undermines the normal processes of democratic republicanism and harms the rule of law. The author analyzes the U.S. Constitution, formerly classified Department of Justice Memos, primary sourced letters, signing statements, executive orders, presidential decrees, and original founding documents to comprehensively conclude that presidential prerogative determines what emergency powers are and how they are to be executed. This book challenges the claim that presidents determine their emergency power with appropriate congressional oversight or consultation. The analysis of the empirical data indicates that presidents do not consult with Congress prior to determining what their emergency powers are and how the president wants to use them. Justin DePlato joins the highly contentious debate over the use of executive power during crisis and offers a sharp argument against an ever-growing centralized and unchecked federal power. He argues that presidents are becoming increasingly reckless when determining and using power during crisis, often times acting unconstitutional.

With the advent of the internet as a medium for performing business transactions, the need for a secure communication channel has never been more paramount. The study of behavioral biometrics - the verification and/or identification of individuals based on the way they provide information to an authentication system - originated from the need for a small footprint, versatile alternative to expensive hardware-based, or physiological, biometrics. As an emerging alternative to these traditional and more well-known physiological biometrics such as fingerprinting or iris scans, behavorial biometrics can offer state-of-the-art solutions to identity management requirements as either a stand-alone system or part of a multi-biometric security system. Whilst there are many existing texts that focus on physiological biometrics or algorithmic approaches deployed in biometrics, Behavioral Biometrics addresses a gap in the existing literature for a text that is solely dedicated to the topic of behavioral biometrics. The author presents a thorough analysis of the latest research into well-known techniques such as signature verification and voice recognition, as well more recently developed and ground-breaking techniques including keyboard/ mouse dynamics, gait analysis, odour analysis and salinity testing, which are ever increasing in reliability; discusses exciting future trends that focus on the brain-computer interface using EEG technology and may one day enable human-machine interaction via brainwave patterns; describes the central applications for the technology within e-commerce and related industries, and provides a number of comprehensive case studies of major implementations that provide the user with a strong sense of the approaches employed in the various subdomains of behavioral biometrics. provides a comprehensive glossary of terms as well as a rich set of references and websites that enable the reader to explore and augment topics as required. Behavioral Biometrics will appeal to graduate and postgraduate students, as well as researchers wishing to explore this fascinating research topic, in areas of biometrics and computer science including classification algorithms, pattern recognition, artificial intelligence & security and digital forensics. In addition, it will serve as a reference for system integrators, CIOs, and related professionals who are charged with implementing security features at their organization.

Human Identification Based on Gait is the first book to address gait as a biometric. Biometrics is now in a unique position where it affects most people's lives. This is especially true of "gait", which is one of the most recent biometrics. Recognizing people by the way they walk and run implies analyzing movement which, in turn, implies analyzing sequences of images, thus requiring memory and computational performance that became available only recently. Human Identification Based on Gait introduces developments from distinguished researchers within this relatively new area of biometrics. This book clearly establishes how human gait is biometric. Human Identification Based on Gait is structured to meet the needs of professionals in industry, as well as advanced-level students in computer science.

When New York–based graphic designers and long-time friends Timothy Goodman and Jessica Walsh found themselves single at the same time, they decided to try an experiment. The old adage says that it takes 40 days to change a habit—could the same be said for love? So they agreed to date each other for 40 days, record their experiences in questionnaires, photographs, videos, texts, and artworks, and post the material on a website they would create for this purpose. What began as a small experiment between two friends became an Internet sensation, drawing 5 million unique (and obsessed) visitors from around the globe to their site and their story since it was launched in July 2013. 40 Days of Dating: An Experiment is a beautifully designed, expanded look at the experiment and the results, including a great deal of material that never made it onto the site, such as who they were as friends and individuals before the 40 days and who they have become since. Note: 40 Days of Dating has a special binding that allows it to open very flat by attaching the endpapers to the inside covers.
