Download or read book Massive Change written by Bruce Mau and published by London : Phaidon. This book was released on 2004-10 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive Change is a modern illustrated primer on the new inventions, technologies, and events that are affecting the human race worldwide. The book is a part of a broader research project by Bruce Mau Design intended to provoke debate and discussion about the familiar objects and techniques that are transforming our lives. In essays, interviews, and provocative imagery aimed at a broad audience, Massive Change explores the changing force of design in the contemporary world, and in doing so expands the definition of design to include the built environment, transportation technologies, revolutionary materials, energy and information systems, and living organisms. The book is divided into 11 heavily illustrated sections covering major areas of change in contemporary society - such as urbanism and architecture, the military, health and living, and wealth and politics. introductory essay, extended captions, and interviews with leading thinkers, including engineers, designers, philosophers, scientists, architects, artists, and writers. Concluding the book is a graphic timeline of significant inventions and world events from 10,000 B.C. to the present. Massive Change is the umbrella name for wide-ranging research project initiated by Bruce Mau Design and the Institute Without Boundaries, a new post-graduate design program headquartered at his studio. The project will include not only this book but also a travelling exhibition, public events, an on-line forum, a documentary television project, posters, and a product line. The overall aim of the project is to explore the changing force of design in the contemporary world. The book focuses on the powerful, newly designed technologies and systems (and the failure of outmoded ones) that increasingly influence our daily lives. the debate about genetically modified foods, the race to decode human the human genome, the development and worldwide trafficking of sophisticated military weapons - even the increasingly intrusive security systems at airports: all are examples of massive changes that involve the field of design. The book presents images and text that explore the impact of these subjects, both the seemingly mundane as well as the mind-boggling and microscopic. As the text in Massive Change explains: No longer associated simply with objects and appearances, design is increasingly understood in a much wider sense as the human capacity to plan and produce desired outcomes. The book is divided into 11 sections, each focusing on a specific economy at work in the world today, both the traditional (such as manufacturing), and the often-invisible (globalization and politics). The pages combine images, extended captions, general essays, and interviews in a clean, simple design. The imagery in Massive Change is irresistible, and stands alone as a compelling reason to own this book. beautiful. For example, a photo of a smoky blue blob, as the caption explains, is really Aerogel, a material developed by NASA to collect fast-moving space dust. And a featherless, naked chicken staring at us from the page is just that: a new, genetically engineered broiler that requires no plucking and yields more meat, a boon to poultry producers yet a frightening harbinger of our future food supply. Massive Change is a well designed, intelligent, visually provocative exploration of the myriad subjects percolating through popular culture: those we read about in magazines and on Web sites but rarely understand in any meaningful way. It poses the question: Now that the human race can do almost anything, what will we do next?

Available in PDF, EPUB and Kindle. Book excerpt: The last ten years have seen a massive growth in the number of connected wireless devices. Billions of devices are connected and managed by wireless networks. At the same time, each device needs a high throughput to support applications such as voice, real-time video, movies, and games. Demands for wireless throughput and the number of wireless devices will always increase. In addition, there is a growing concern about energy consumption of wireless communication systems. Thus, future wireless systems have to satisfy three main requirements: i) having a high throughput; ii) simultaneously serving many users; and iii) having less energy consumption. Massive multiple-input multiple-output (MIMO) technology, where a base station (BS) equipped with very large number of antennas (collocated or distributed) serves many users in the same time-frequency resource, can meet the above requirements, and hence, it is a promising candidate technology for next generations of wireless systems. With massive antenna arrays at the BS, for most propagation environments, the channels become favorable, i.e., the channel vectors between the users and the BS are (nearly) pairwisely orthogonal, and hence, linear processing is nearly optimal. A huge throughput and energy efficiency can be achieved due to the multiplexing gain and the array gain. In particular, with a simple power control scheme, Massive MIMO can offer uniformly good service for all users. In this dissertation, we focus on the performance of Massive MIMO. The dissertation consists of two main parts: fundamentals and system designs of Massive MIMO. In the first part, we focus on fundamental limits of the system performance under practical constraints such as low complexity processing, limited length of each coherence interval, intercell interference, and finite-dimensional channels. We first study the potential for power savings of the Massive MIMO uplink with maximum-ratio combining (MRC), zero-forcing, and minimum mean-square error receivers, under perfect and imperfect channels. The energy and spectral efficiency tradeoff is investigated. Secondly, we consider a physical channel model where the angular domain is divided into a finite number of distinct directions. A lower bound on the capacity is derived, and the effect of pilot contamination in this finite-dimensional channel model is analyzed. Finally, some aspects of favorable propagation in Massive MIMO under Rayleigh fading and line-of-sight (LoS) channels are investigated. We show that both Rayleigh fading and LoS environments offer favorable propagation. In the second part, based on the fundamental analysis in the first part, we propose some system designs for Massive MIMO. The acquisition of channel state information (CSI) is very importantin Massive MIMO. Typically, the channels are estimated at the BS through uplink training. Owing to the limited length of the coherence interval, the system performance is limited by pilot contamination. To reduce the pilot contamination effect, we propose an eigenvalue-decomposition-based scheme to estimate the channel directly from the received data. The proposed scheme results in better performance compared with the conventional training schemes due to the reduced pilot contamination. Another important issue of CSI acquisition in Massive MIMO is how to acquire CSI at the users. To address this issue, we propose two channel estimation schemes at the users: i) a downlink "beamforming training" scheme, and ii) a method for blind estimation of the effective downlink channel gains. In both schemes, the channel estimation overhead is independent of the number of BS antennas. We also derive the optimal pilot and data powers as well as the training duration allocation to maximize the sum spectral efficiency of the Massive MIMO uplink with MRC receivers, for a given total energy budget spent in a coherence interval. Finally, applications of Massive MIMO in relay channels are proposed and analyzed. Specifically, we consider multipair relaying systems where many sources simultaneously communicate with many destinations in the same time-frequency resource with the help of a massive MIMO relay. A massive MIMO relay is equipped with many collocated or distributed antennas. We consider different duplexing modes (full-duplex and half-duplex) and different relaying protocols (amplify-and-forward, decode-and-forward, two-way relaying, and one-way relaying) at the relay. The potential benefits of massive MIMO technology in these relaying systems are explored in terms of spectral efficiency and power efficiency.

This book was released on 2014-07-17 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded the American Astronomical Society (AAS) Rodger Doxsey Travel Prize, and with a foreword by thesis supervisor Professor Shardha Jogee at the University of Texas at Austin, this thesis discusses one of the primary outstanding problems in extragalactic astronomy: how galaxies form and evolve. Galaxies consist of two fundamental kinds of structure: rotationally supported disks and spheroidal/triaxial structures supported by random stellar motions. Understanding the balance between these galaxy components is vital to comprehending the relative importance of the different mechanisms (galaxy collisions, gas accretion and internal secular processes) that assemble and shape galaxies. Using panchromatic imaging from some of the largest and deepest space-based galaxy surveys, an empirical census of galaxy structure is made for galaxies at different cosmic epochs and in environments spanning low to extremely high galaxy number densities. An important result of this work is that disk structures are far more prevalent in massive galaxies than previously thought. The associated challenges raised for contemporary theoretical models of galaxy formation are discussed. The method of galaxy structural decomposition is treated thoroughly since it is relevant for future studies of galaxy structure using next-generation facilities, like the James Webb Space Telescope and the ground-based Giant Magellan Telescope with adaptive optics.
