Fedor V. Fomin, Daniel Lokshtanov, Saket Saurabh, Meirav Zehavi
R1,304 Discovery Miles 13 040 Ships in 10 - 15 working days

Preprocessing, or data reduction, is a standard technique for simplifying and speeding up computation. Written by a team of experts in the field, this book introduces a rapidly developing area of preprocessing analysis known as kernelization. The authors provide an overview of basic methods and important results, with accessible explanations of the most recent advances in the area, such as meta-kernelization, representative sets, polynomial lower bounds, and lossy kernelization. The text is divided into four parts, which cover the different theoretical aspects of the area: upper bounds, meta-theorems, lower bounds, and beyond kernelization. The methods are demonstrated through extensive examples using a single data set. Written to be self-contained, the book only requires a basic background in algorithmics and will be of use to professionals, researchers and graduate students in theoretical computer science, optimization, combinatorics, and related fields.

R1,213 Discovery Miles 12 130 Ships in 10 - 15 working days

High-throughput sequencing has revolutionised the field of biological sequence analysis. Its application has enabled researchers to address important biological questions, often for the first time. This book provides an integrated presentation of the fundamental algorithms and data structures that power modern sequence analysis workflows. The topics covered range from the foundations of biological sequence analysis (alignments and hidden Markov models), to classical index structures (k-mer indexes, suffix arrays and suffix trees), Burrows-Wheeler indexes, graph algorithms and a number of advanced omics applications. The chapters feature numerous examples, algorithm visualisations, exercises and problems, each chosen to reflect the steps of large-scale sequencing projects, including read alignment, variant calling, haplotyping, fragment assembly, alignment-free genome comparison, transcript prediction and analysis of metagenomic samples. Each biological problem is accompanied by precise formulations, providing graduate students and researchers in bioinformatics and computer science with a powerful toolkit for the emerging applications of high-throughput sequencing.

Cybersecurity - Executive Order 13636 & the Critical Infrastructure Framework (Paperback): Anastacia D'Ambrosio Cybersecurity - Executive Order 13636 & the Critical Infrastructure Framework (Paperback)
Anastacia D'Ambrosio
R1,476 Discovery Miles 14 760 Ships in 10 - 15 working days

Cyberthreats to U.S. infrastructure and other assets are a growing concern to policymakers. Information and communications technology (ICT) is ubiquitous and relied upon for government services, corporate business processes, and individual professional and personal pursuits -- almost every facet of modern life. Many ICT devices and other components are interdependent, and disruption of one component may have a negative, cascading effect on others. A denial of service, theft or manipulation of data, or damage to critical infrastructure through a cyber-based attack could have significant impacts on national security, the economy, and the livelihood and safety of individual citizens. The federal legislative framework for cybersecurity is complex, with more than 50 statutes addressing various aspects of it either directly or indirectly. Many observers do not believe that the current framework is sufficient to address the growing concerns about the security of cyberspace in the United States. However, no major cybersecurity legislation has been enacted since 2002. This book provides an overview of the 2013 cybersecurity executive order and discusses considerations for Congress. It also provides ways to improve the critical infrastructure of cybersecurity.

Logic Programming - Theory, Practices and Challenges (Paperback): Marcus J Lambert Logic Programming - Theory, Practices and Challenges (Paperback)
Marcus J Lambert
R2,392 Discovery Miles 23 920 Ships in 10 - 15 working days

Prolog for logic programming is one of the most intensively studied software languages in the 1980s. During the same period, the data-flow model for parallel computation attracted a lot of attention of researchers in the computer science; hence, it was very natural that several approaches were tried toward combining the two and implementing logic programs in parallel machines with the data-flow architecture. These approaches, however, were rather indirect ones in the sense that they developed programs describing AND/OR-parallelism for deduction using a data-flow language and executed them in a data-flow computer, and yet did not devise a direct' model for parallel execution (reasoning) of a logic program. This book discusses fuzzy logic inferencing for Pong; dislog; SEProlog; and provides direct graphical representations of first-order logic for inference.

The Philosophy of Information (Paperback): Luciano Floridi The Philosophy of Information (Paperback)
Luciano Floridi
R684 Discovery Miles 6 840 Ships in 10 - 15 working days

Luciano Floridi presents a book that will set the agenda for the philosophy of information. PI is the philosophical field concerned with (1) the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and (2) the elaboration and application of information-theoretic and computational methodologies to philosophical problems. This book lays down, for the first time, the conceptual foundations for this new area of research. It does so systematically, by pursuing three goals. Its metatheoretical goal is to describe what the philosophy of information is, its problems, approaches, and methods. Its introductory goal is to help the reader to gain a better grasp of the complex and multifarious nature of the various concepts and phenomena related to information. Its analytic goal is to answer several key theoretical questions of great philosophical interest, arising from the investigation of semantic information.

John Von Neumann; Foreword by Ray Kurzweil
R348 Discovery Miles 3 480 Ships in 10 - 15 working days

First published in 1958, John von Neumann's classic work The Computer and the Brain explored the analogies between computing machines and the living human brain. Von Neumann showed that the brain operates both digitally and analogically, but also has its own unique statistical language. And more than fifty years after its inception the von Neumann architecture - an organizational framework for computer design - still lies at the heart of today's machines. In his foreword to this new edition, Ray Kurzweil, a futurist famous for his own musings on the relationship between technology and consciousness, places von Neumann's work in a historical context and shows how it remains relevant today.

R621 Discovery Miles 6 210 Ships in 10 - 15 working days

We -- the users turned creators and distributors of content -- are TIME's Person of the Year 2006, and AdAge's Advertising Agency of the Year 2007. We form a new Generation C. We have MySpace, YouTube, and OurMedia; we run social software, and drive the development of Web 2.0. But beyond the hype, what's really going on? In this groundbreaking exploration of our developing participatory online culture, Axel Bruns establishes the core principles which drive the rise of collaborative content creation in environments, from open source through blogs and Wikipedia to Second Life. This book shows that what's emerging here is no longer just a new form of content production, but a new process for the continuous creation and extension of knowledge and art by collaborative communities: produsage. The implications of the gradual shift from production to produsage are profound, and will affect the very core of our culture, economy, society, and democracy.

TORUS 1 - Toward an Open Resource Using Services - Cloud Computing for Environmental Data (Hardcover): Dominique Laffly TORUS 1 - Toward an Open Resource Using Services - Cloud Computing for Environmental Data (Hardcover)
Dominique Laffly
R3,333 Discovery Miles 33 330 Ships in 7 - 11 working days

This book, presented in three volumes, examines environmental disciplines in relation to major players in contemporary science: Big Data, artificial intelligence and cloud computing. Today, there is a real sense of urgency regarding the evolution of computer technology, the ever-increasing volume of data, threats to our climate and the sustainable development of our planet. As such, we need to reduce technology just as much as we need to bridge the global socio-economic gap between the North and South; between universal free access to data (open data) and free software (open source). In this book, we pay particular attention to certain environmental subjects, in order to enrich our understanding of cloud computing. These subjects are: erosion; urban air pollution and atmospheric pollution in Southeast Asia; melting permafrost (causing the accelerated release of soil organic carbon in the atmosphere); alert systems of environmental hazards (such as forest fires, prospective modeling of socio-spatial practices and land use); and web fountains of geographical data. Finally, this book asks the question: in order to find a pattern in the data, how do we move from a traditional computing model-based world to pure mathematical research? After thorough examination of this topic, we conclude that this goal is both transdisciplinary and achievable.
