One of the most persistent concerns about the future is whether it will be dominated by the predictive algorithms of AI – and, if so, what this will mean for our behaviour, for our institutions and for what it means to be human. AI changes our experience of time and the future and challenges our identities, yet we are blinded by its efficiency and fail to understand how it affects us. At the heart of our trust in AI lies a paradox: we leverage AI to increase our control over the future and uncertainty, while at the same time the performativity of AI, the power it has to make us act in the ways it predicts, reduces our agency over the future. This happens when we forget that that we humans have created the digital technologies to which we attribute agency. These developments also challenge the narrative of progress, which played such a central role in modernity and is based on the hubris of total control. We are now moving into an era where this control is limited as AI monitors our actions, posing the threat of surveillance, but also offering the opportunity to reappropriate control and transform it into care. As we try to adjust to a world in which algorithms, robots and avatars play an ever-increasing role, we need to understand better the limitations of AI and how their predictions affect our agency, while at the same time having the courage to embrace the uncertainty of the future.

This book covers the principles of modeling and simulation of nonlinear distortion in wireless communication systems with MATLAB simulations and techniques In this book, the author describes the principles of modeling and simulation of nonlinear distortion in single and multichannel wireless communication systems using both deterministic and stochastic signals. Models and simulation methods of nonlinear amplifiers explain in detail how to analyze and evaluate the performance of data communication links under nonlinear amplification. The book addresses the analysis of nonlinear systems with stochastic inputs and establishes the performance metrics of communication systems with regard to nonlinearity. In addition, the author also discusses the problem of how to embed models of distortion in system-level simulators such as MATLAB and MATLAB Simulink and provides practical techniques that professionals can use on their own projects. Finally, the book explores simulation and programming issues and provides a comprehensive reference of simulation tools for nonlinearity in wireless communication systems. Key Features: Covers the theory, models and simulation tools needed for understanding nonlinearity and nonlinear distortion in wireless systems Presents simulation and modeling techniques for nonlinear distortion in wireless channels using MATLAB Uses random process theory to develop simulation tools for predicting nonlinear system performance with real-world wireless communication signals Focuses on simulation examples of real-world communication systems under nonlinearity Includes an accompanying website containing MATLAB code This book will be an invaluable reference for researchers, RF engineers, and communication system engineers working in the field. Graduate students and professors undertaking related courses will also find the book of interest.

The Self-Taught Computer Scientist is Cory Althoff's follow-up to The Self-Taught Programmer , which inspired hundreds of thousands of professionals to learn how to program outside of school. In The Self-Taught Programmer , Cory showed readers why you don't need a computer science degree to program professionally and taught the programming fundamentals he used to go from a complete beginner to a software engineer at eBay without one. In The Self-Taught Computer Scientist , Cory teaches you the computer science concepts that all self-taught programmers should understand to have outstanding careers. The Self-Taught Computer Scientist will not only make you a better programmer; it will also help you pass your technical interview: the interview all programmers have to pass to land a new job. Whether you are preparing to apply for jobs or sharpen your computer science knowledge, reading The Self-Taught Computer Scientist will improve your programming career. It's written for complete beginners, so you should have no problem reading it even if you've never studied computer science before.

Smith-Acu?a illuminates the structural hierarchy, roles, and boundaries that give a system structure. The relationship between parts and wholes is both simple and profound, and particularly important in looking at systems structure. These morsels of wisdom are good examples of Smith-Acu?a's grace as a systems theory tour guide: one moment she's digging deeper into the nuances among the theories, the next moment she's simplifying without dumbing down, but in a manner that is enormously liberating. We enjoy the fun, full, and informed journey with her. —Frank S. Pittman III, MD A practical presentation of systems theory as a fundamental model for clinical practice Valuable for seasoned mental health professionals as well as those in training, Systems Theory in Action presents systems theory—the unifying principles surrounding the organization and functioning of systems—as it applies to individual, couples, and family therapy. This innovative book explores systems theory as an effective model for general mental health practice. It examines the role systems theory can play, specifically in understanding clients' presenting problems in context, within the various systems and subsystems in which the problems are embedded. Filled with realistic clinical stories illustrating relevant concepts that tie theory to technique, Systems Theory in Action takes an in-depth look at: Systems theory as a solid guide through the dynamic process of psychotherapy The multilayered value of observing human interactions through a systems view Systemic thinking, its core components, and how it serves to reveal a «big picture» view of clients and their presenting problems Systems Theory in Action is a unique contribution to the field, translating the technical terminology of general systems thinking into common, everyday language.
