Time-Space Compression by Barney Warf Pdf

If geography is the study of how human beings are stretched over the earth’s surface, a vital part of that process is how we know and feel about space and time. Although space and time appear as "natural" and outside of society, they are in fact social constructions; every society develops different ways of measuring, organizing, and perceiving them. Given steady increases in the volume and velocity of social transactions over space, time and space have steadily "shrunk" via the process of time-space compression. By changing the time-space prisms of daily life – how people use their times and spaces, the opportunities and constraints they face, the meanings they attach to them – time-space compression is simultaneously cultural, social, political, and psychological in nature. This book explores how various social institutions and technologies historically generated enormous improvements in transportation and communications that produced transformative reductions in the time and cost of interactions among places, creating ever-changing geographies of centrality and peripherality. Warf invokes a global perspective on early modern, late modern, and postmodern capitalism. He makes use of data concerning travel times at various historical junctures, maps of distances between places at different historical moments, anecdotal analyses based on published accounts of people’s sense of place, examinations of cultural forms that represented space (e.g., paintings), and quotes about the culture of speed. Warf shows how time-space compression varies under different historical and geographical conditions, indicating that it is not one, single, homogenous process but a complex, contingent, and contested one. This book will be useful book for those studying and researching Geography, History, Sociology, and Political Science, as well as Anthropology, and Philosophy.

Implementing IBM Real-time Compression on the IBM XIV Storage System by Guenter Rebmann,Albert Verhoeff,Megan Gilge,IBM Redbooks Pdf

IBM® Real-time CompressionTM is fully integrated in the IBM XIV® Storage System Gen3 with software version 11.6. Real-time Compression provides the possibility to store 2 - 5 times more data per XIV system, without additional hardware. This technology also expands the storage-replication-related bandwidth, and can significantly decrease the total cost of ownership (TCO). Using compression for replication and for volume migration with IBM Hyper-Scale Mobility is faster, and requires less bandwidth for the interlink connections between the IBM XIV storage systems, because the data that is transferred through these links is already compressed. IBM Real-time Compression uses patented IBM Random Access Compression Engine (RACE) technology, achieving field-proven compression ratios and performance with compressible data. This IBM RedpaperTM publication helps administrators understand and implement IBM Real-time Compression on the IBM XIV Gen3 storage system.

Hyperspectral Data Compression by Giovanni Motta,Francesco Rizzo,James A. Storer Pdf

Hyperspectral Data Compression provides a survey of recent results in the field of compression of remote sensed 3D data, with a particular interest in hyperspectral imagery. Chapter 1 addresses compression architecture, and reviews and compares compression methods. Chapters 2 through 4 focus on lossless compression (where the decompressed image must be bit for bit identical to the original). Chapter 5, contributed by the editors, describes a lossless algorithm based on vector quantization with extensions to near lossless and possibly lossy compression for efficient browning and pure pixel classification. Chapter 6 deals with near lossless compression while. Chapter 7 considers lossy techniques constrained by almost perfect classification. Chapters 8 through 12 address lossy compression of hyperspectral imagery, where there is a tradeoff between compression achieved and the quality of the decompressed image. Chapter 13 examines artifacts that can arise from lossy compression.

Compression of an array of similar crash test simulation results by Stefan Peter Müller Pdf

Big data thrives on extracting knowledge from a large number of data sets. But how is an application possible when a single data set is several gigabytes in size? The innovative data compression techniques from the field of machine learning and modeling using Bayesian networks, which have been theoretically developed and practically implemented here, can reduce these huge amounts of data to a manageable size. By eliminating redundancies in location, time, and between simulation results, data reductions to less than 1% of the original size are possible. The developed method represents a promising approach whose use goes far beyond the application example of crash test simulations chosen here.

Image and Video Compression Standards by Vasudev Bhaskaran,Konstantinos Konstantinides Pdf

New to the Second Edition: offers the latest developments in standards activities (JPEG-LS, MPEG-4, MPEG-7, and H.263) provides a comprehensive review of recent activities on multimedia enhanced processors, multimedia coprocessors, and dedicated processors, including examples from industry. Image and Video Compression Standards: Algorithms and Architectures, Second Edition presents an introduction to the algorithms and architectures that form the underpinnings of the image and video compressions standards, including JPEG (compression of still-images), H.261 and H.263 (video teleconferencing), and MPEG-1 and MPEG-2 (video storage and broadcasting). The next generation of audiovisual coding standards, such as MPEG-4 and MPEG-7, are also briefly described. In addition, the book covers the MPEG and Dolby AC-3 audio coding standards and emerging techniques for image and video compression, such as those based on wavelets and vector quantization. Image and Video Compression Standards: Algorithms and Architectures, Second Edition emphasizes the foundations of these standards; namely, techniques such as predictive coding, transform-based coding such as the discrete cosine transform (DCT), motion estimation, motion compensation, and entropy coding, as well as how they are applied in the standards. The implementation details of each standard are avoided; however, the book provides all the material necessary to understand the workings of each of the compression standards, including information that can be used by the reader to evaluate the efficiency of various software and hardware implementations conforming to these standards. Particular emphasis is placed on those algorithms and architectures that have been found to be useful in practical software or hardware implementations. Image and Video Compression Standards: Algorithms and Architectures, emSecond Edition uniquely covers all major standards (JPEG, MPEG-1, MPEG-2, MPEG-4, H.261, H.263) in a simple and tutorial manner, while fully addressing the architectural considerations involved when implementing these standards. As such, it serves as a valuable reference for the graduate student, researcher or engineer. The book is also used frequently as a text for courses on the subject, in both academic and professional settings.

Compression Schemes for Mining Large Datasets by T. Ravindra Babu,M. Narasimha Murty,S.V. Subrahmanya Pdf

This book addresses the challenges of data abstraction generation using a least number of database scans, compressing data through novel lossy and non-lossy schemes, and carrying out clustering and classification directly in the compressed domain. Schemes are presented which are shown to be efficient both in terms of space and time, while simultaneously providing the same or better classification accuracy. Features: describes a non-lossy compression scheme based on run-length encoding of patterns with binary valued features; proposes a lossy compression scheme that recognizes a pattern as a sequence of features and identifying subsequences; examines whether the identification of prototypes and features can be achieved simultaneously through lossy compression and efficient clustering; discusses ways to make use of domain knowledge in generating abstraction; reviews optimal prototype selection using genetic algorithms; suggests possible ways of dealing with big data problems using multiagent systems.
