Personalized Privacy Protection in Big Data (Data Analytics)
by Shui Yu Youyang Qu Mohammad Reza Nosouhi Lei CuiThis book presents the data privacy protection which has been extensively applied in our current era of big data. However, research into big data privacy is still in its infancy. Given the fact that existing protection methods can result in low data utility and unbalanced trade-offs, personalized privacy protection has become a rapidly expanding research topic.In this book, the authors explore emerging threats and existing privacy protection methods, and discuss in detail both the advantages and disadvantages of personalized privacy protection. Traditional methods, such as differential privacy and cryptography, are discussed using a comparative and intersectional approach, and are contrasted with emerging methods like federated learning and generative adversarial nets.The advances discussed cover various applications, e.g. cyber-physical systems, social networks, and location-based services. Given its scope, the book is of interest to scientists, policy-makers, researchers, and postgraduates alike.
Personalized Psychiatry: Big Data Analytics in Mental Health
by Ives Cavalcante Passos Benson Mwangi Flávio KapczinskiThis book integrates the concepts of big data analytics into mental health practice and research.Mental disorders represent a public health challenge of staggering proportions. According to the most recent Global Burden of Disease study, psychiatric disorders constitute the leading cause of years lost to disability. The high morbidity and mortality related to these conditions are proportional to the potential for overall health gains if mental disorders can be more effectively diagnosed and treated. In order to fill these gaps, analysis in science, industry, and government seeks to use big data for a variety of problems, including clinical outcomes and diagnosis in psychiatry. Multiple mental healthcare providers and research laboratories are increasingly using large data sets to fulfill their mission. Briefly, big data is characterized by high volume, high velocity, variety and veracity of information, and to be useful it must be analyzed, interpreted, and acted upon. As such, focus has to shift to new analytical tools from the field of machine learning that will be critical for anyone practicing medicine, psychiatry and behavioral sciences in the 21st century. Big data analytics is gaining traction in psychiatric research, being used to provide predictive models for both clinical practice and public health systems. As compared with traditional statistical methods that provide primarily average group-level results, big data analytics allows predictions and stratification of clinical outcomes at an individual subject level.Personalized Psychiatry – Big Data Analytics in Mental Health provides a unique opportunity to showcase innovative solutions tackling complex problems in mental health using big data and machine learning. It represents an interesting platform to work with key opinion leaders to document current achievements, introduce new concepts as well as project the future role of big data and machine learning in mental health.
Personalizing Haptics: From Individuals' Sense-Making Schemas to End-User Haptic Tools (Springer Series on Touch and Haptic Systems)
by Hasti SeifiThis monograph presents a vision for haptic personalization tools and lays the foundations for achieving it. Effective haptic personalization requires a suite of tools unified by one underlying conceptual model that can easily be incorporated into users’ workflows with various applications. Toward this vision, the book introduces three mechanisms for haptic personalization and details development of two of them into: 1) an efficient interface for choosing from a large haptic library, and 2) three emotion controls for adjusting haptic signals. A series of quantitative experiments identifies five schemas (engineering, sensation, emotion, metaphor, and usage examples) for how end-users think and talk about haptic sensations and characterizes them as the underlying model for the personalization tools. Personalizing Haptics highlights the need for scalable haptic evaluation methodologies and presents two methodologies for large-scale in-lab evaluation and online crowdsourcing of haptics. While the work focuses on vibrotactile signals as the most mature and accessible type of haptic feedback for end-users, the concepts and findings extend to other categories of haptics. Taking haptics to the crowds will require haptic design practices to go beyond the current one-size-fits-all approach to satisfy users’ diverse perceptual, functional, and hedonic needs reported in the literature. This book provides a starting point for students, researchers, and practitioners in academia or industry who aim to adapt their haptic and multisensory designs to the needs and preferences of a wide audience.
Personas - User Focused Design
by Lene NielsenPeople relate to other people, not to simplified types or segments. This is the concept that underpins this book. Personas, a user centered design methodology covers topics from interaction design within IT, through to issues surrounding product design, communication, and marketing. Project developers need to understand how users approach their products from the product's infancy, and regardless of what the product might be. Developers should be able to describe the user of the product via vivid depictions, as if they - with their different attitudes, desires and habits - were already using the product. In doing so they can more clearly formulate how to turn the product's potential into reality. With contributions from professionals from Australia, Brazil, Finland, Japan, Russia, and the UK presenting real-world examples of persona method, this book will provide readers with valuable insights into this exciting research area. The inspiration to create user descriptions includes character-driven narratives, and the film Thelma & Louise is analyzed in order to understand how the development process can also be an engaging story in various professional contexts. With a solid foundation in her own research at the IT University of Copenhagen and more than five years of experience in solving problems for businesses, Lene Nielsen is Denmark's leading expert in the persona method. She has a PhD in personas and scenarios, and through her research and practical experiences she has developed her own approach to the method - 10 Steps to Personas. Personas - User Focused Design presents a step-by-step methodology of personas which will be of interest to developers of IT, communications solutions and innovative products.

Perspectives in Electronic Structure Theory
by Roman F. NalewajskiThe understanding in science implies insights from several different points of view. Alternative modern outlooks on electronic structure of atoms and molecules, all rooted in quantum mechanics, are presented in a single text. Together these complementary perspectives provide a deeper understanding of the localization of electrons and bonds, the origins of chemical interaction and reactivity behavior, the interaction between the geometric and electronic structure of molecules, etc. In the opening two parts the basic principles and techniques of the contemporary computational and conceptual quantum chemistry are presented, within both the wave-function and electron-density theories. This background material is followed by a discussion of chemical concepts, including stages of the bond-formation processes, chemical valence and bond-multiplicity indices, the hardness/softness descriptors of molecules and reactants, and general chemical reactivity/stability principles. The insights from Information Theory, the basic elements of which are briefly introduced, including the entropic origins and Orbital Communication Theory of the chemical bond, are the subject of Part IV. The importance of the non-additive (interference) information tools in exploring patterns of chemical bonds and their covalent and ionic components will be emphasized.
