Bored and Brilliant: How Spacing Out Can Unlock Your Most Productive and Creative Self
by Manoush Zomorodi"Bored and Brilliant shows the fascinating side of boredom. Manoush Zomorodi investigates cutting-edge research as well as compelling (and often funny) real-life examples to demonstrate that boredom is actually a crucial tool for making our lives happier, more productive, and more creative. What’s more, the book is crammed with practical exercises for anyone who wants to reclaim the power of spacing out – deleting the Two Dots app, for instance, or having a photo-free day, or taking a 'fakecation'." —Gretchen Rubin, author of #1 NYT Bestseller The Happiness Project"Bored and Brilliant is full of easy steps to make each day more effective and every life more intentional. Manoush’s mix of personal stories, neuroscience, and data will convince you that boredom is actually a gift." —Charles Duhigg, author of The Power of Habit and Smarter, Faster, BetterIt’s time to move “doing nothing” to the top of your to-do list.In 2015 Manoush Zomorodi, host of WNYC’s popular podcast and radio show Note to Self, led tens of thousands of listeners through an experiment to help them unplug from their devices, get bored, jump-start their creativity, and change their lives. Bored and Brilliant builds on that experiment to show us how to rethink our gadget use to live better and smarter in this new digital ecosystem. Manoush explains the connection between boredom and original thinking, exploring how we can harness boredom’s hidden benefits to become our most productive and creative selves without totally abandoning our gadgets in the process. Grounding the book in the neuroscience and cognitive psychology of “mind wandering” what our brains do when we're doing nothing at all—Manoush includes practical steps you can take to ease the nonstop busyness and enhance your ability to dream, wonder, and gain clarity in your work and life. The outcome is mind-blowing. Unplug and read on.

Media Convergence Handbook - Vol. 1
by Cinzia Dal Zotto Artur LugmayrThe Media Convergence Handbook sheds new light on the complexity of media convergence and the related business challenges. Approaching the topic from a managerial, technological as well as end-consumer perspective, it acts as a reference book and educational resource in the field. Media convergence at business level may imply transforming business models and using multiplatform content production and distribution tools. However, it is shown that the implementation of convergence strategies can only succeed when expectations and aspirations of every actor involved are taken into account. Media consumers, content producers and managers face different challenges in the process of media convergence. Volume I of the Media Convergence Handbook encourages an active discourse on media convergence by introducing the concept through general perspective articles and addressing the real-world challenges of conversion in the publishing, broadcasting and social media sectors.
Physical-Layer Security for Cooperative Relay Networks
by Yulong Zou Jia ZhuThis book presents physical-layer security as a promising paradigm for achieving the information-theoretic secrecy required for wireless networks. It explains how wireless networks are extremely vulnerable to eavesdropping attacks and discusses a range of security techniques including information-theoretic security, artificial noise aided security, security-oriented beamforming, and diversity assisted security approaches. It also provides an overview of the cooperative relaying methods for wireless networks such as orthogonal relaying, non-orthogonal relaying, and relay selection. Chapters explore the relay-selection designs for improving wireless secrecy against eavesdropping in time-varying fading environments and a joint relay and jammer selection for wireless physical-layer security, where a relay is used to assist the transmission from the source to destination and a friendly jammer is employed to transmit an artificial noise for confusing the eavesdropper. Additionally, the security-reliability tradeoff (SRT) is mathematically characterized for wireless communications and two main relay-selection schemes, the single-relay and multi-relay selection, are devised for the wireless SRT improvement. In the single-relay selection, only the single best relay is chosen for assisting the wireless transmission, while the multi-relay selection invokes multiple relays for simultaneously forwarding the source transmission to the destination. Physical-Layer Security for Cooperative Relay Networks is designed for researchers and professionals working with networking or wireless security. Advanced-level students interested in networks, wireless, or privacy will also find this book a useful resource.

Los dueños de internet: Cómo nos dominan los gigantes de la tecnología y qué hacer para cambiarlo
by Natalia ZuazoEste libro propone cambiar la lógica monopólica de internet y adueñarnos de nuestro propio modo de relacionarnos con la tecnología para vivir en un mundo más equitativo. En este preciso instante, la mitad de las personas están conectadas a Google, Microsoft, Facebook, Apple y Amazon. En los últimos años, las grandes plataformas tecnológicas se convirtieron en las empresas más ricas del planeta sin usar la violencia. Su poder se consolidó gracias a los millones de usuarios como nosotros que les confían su atención y sus datos a través de teléfonos móviles y algoritmos. Hoy internet es un club de cinco grandes monopolios que generan desigualdad. Un puñado de corporaciones domina el mundo como antes lo hicieron las potencias coloniales. ¿Cómo construyó Microsoft un imperio del conocimiento? ¿Cómo predice Google nuestros movimientos? ¿Cómo cimentó Facebook su poderío informativo? ¿Cómo maneja Uber el mundo de transporte? Pero sobre todo, ¿cómo podemos revertir esta situación? En este libro, la periodista especializada en tecnopolítica Natalia Zuazo se sumerge en el universo de estas grandes corporaciones para entender sus fines. Y cuenta otras historias donde la tecnología está siendo usada con otra lógica: la de una sociedad más equitativa. "Las grandes plataformas tecnológicas son los monopolios que hoy dominan el mundo. Unos pocos jugadores controlan la actividad en cada sector. Google lidera las búsquedas, la publicidad y el aprendizaje automatizado. Facebook, el mercado de las noticias y la información. Amazon dirige el comercio en gran parte de Occidente mientras avanza en generar y distribuir sus propios productos. Uber no sólo quiere intermediar y ganar dinero con cada viaje, sino que busca convertirse en la empresa que transporte los bienes del futuro, incluso sin necesidad de conductores. Con remera y un ejército de relacionistas públicos que difunden anuncios a favor de los más necesitados, hoy el Club de los Cinco ha conquistado el mundo como antes lo hicieron las grandes potencias. La diferencia es que en vez de construir palacios y grandes murallas, se instalan en oficinas abiertas y llenas de luz en Silicon Valley. Y en lugar de evangelizar con sacerdotes y predicadores, se nutren del capitalismo del like y de cada dato que cedemos de nuestra vida. Cien años después, vivimos un nuevo colonialismo."
Numerical Approximation of Exact Controls for Waves
by Enrique Zuazua Sylvain ErvedozaThis book is devoted to fully developing and comparing the two main approaches to the numerical approximation of controls for wave propagation phenomena: the continuous and the discrete. This is accomplished in the abstract functional setting of conservative semigroups.The main results of the work unify, to a large extent, these two approaches, which yield similaralgorithms and convergence rates. The discrete approach, however, gives not only efficient numerical approximations of the continuous controls, but also ensures some partial controllability properties of the finite-dimensional approximated dynamics. Moreover, it has the advantage of leading to iterative approximation processes that converge without a limiting threshold in the number of iterations. Such a threshold, which is hard to compute and estimate in practice, is a drawback of the methods emanating from the continuous approach. To complement this theory, the book provides convergence results for the discrete wave equation when discretized using finite differences and proves the convergence of the discrete wave equation with non-homogeneous Dirichlet conditions. The first book to explore these topics in depth, "On the Numerical Approximations of Controls for Waves" has rich applications to data assimilation problems and will be of interest to researchers who deal with wave approximations.
