R2,861 Discovery Miles 28 610 Ships in 10 - 15 working days

Wireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.

The past few years have seen a major change in computing systems, as growing data volumes and stalling processor speeds require more and more applications to scale out to clusters. Today, a myriad data sources, from the Internet to business operations to scientific instruments, produce large and valuable data streams. However, the processing capabilities of single machines have not kept up with the size of data. As a result, organizations increasingly need to scale out their computations over clusters. At the same time, the speed and sophistication required of data processing have grown. In addition to simple queries, complex algorithms like machine learning and graph analysis are becoming common. And in addition to batch processing, streaming analysis of real-time data is required to let organizations take timely action. Future computing platforms will need to not only scale out traditional workloads, but support these new applications too. This book, a revised version of the 2014 ACM Dissertation Award winning dissertation, proposes an architecture for cluster computing systems that can tackle emerging data processing workloads at scale. Whereas early cluster computing systems, like MapReduce, handled batch processing, our architecture also enables streaming and interactive queries, while keeping MapReduce's scalability and fault tolerance. And whereas most deployed systems only support simple one-pass computations (e.g., SQL queries), ours also extends to the multi-pass algorithms required for complex analytics like machine learning. Finally, unlike the specialized systems proposed for some of these workloads, our architecture allows these computations to be combined, enabling rich new applications that intermix, for example, streaming and batch processing. We achieve these results through a simple extension to MapReduce that adds primitives for data sharing, called Resilient Distributed Datasets (RDDs). We show that this is enough to capture a wide range of workloads. We implement RDDs in the open source Spark system, which we evaluate using synthetic and real workloads. Spark matches or exceeds the performance of specialized systems in many domains, while offering stronger fault tolerance properties and allowing these workloads to be combined. Finally, we examine the generality of RDDs from both a theoretical modeling perspective and a systems perspective. This version of the dissertation makes corrections throughout the text and adds a new section on the evolution of Apache Spark in industry since 2014. In addition, editing, formatting, and links for the references have been added.

Computational Prediction of Protein Complexes from Protein Interaction Networks (Hardcover): Sriganesh Srihari, Chern Han Yong,... Computational Prediction of Protein Complexes from Protein Interaction Networks (Hardcover)
Sriganesh Srihari, Chern Han Yong, Limsoon Wong; Series edited by M.Tamer Ozsu
R2,493 Discovery Miles 24 930 Ships in 18 - 22 working days

Complexes of physically interacting proteins constitute fundamental functional units that drive almost all biological processes within cells. A faithful reconstruction of the entire set of protein complexes (the "complexosome") is therefore important not only to understand the composition of complexes but also the higher level functional organization within cells. Advances over the last several years, particularly through the use of high-throughput proteomics techniques, have made it possible to map substantial fractions of protein interactions (the "interactomes") from model organisms including Arabidopsis thaliana (a flowering plant), Caenorhabditis elegans (a nematode), Drosophila melanogaster (fruit fly), and Saccharomyces cerevisiae (budding yeast). These interaction datasets have enabled systematic inquiry into the identification and study of protein complexes from organisms. Computational methods have played a significant role in this context, by contributing accurate, efficient, and exhaustive ways to analyze the enormous amounts of data. These methods have helped to compensate for some of the limitations in experimental datasets including the presence of biological and technical noise and the relative paucity of credible interactions. In this book, we systematically walk through computational methods devised to date (approximately between 2000 and 2016) for identifying protein complexes from the network of protein interactions (the protein-protein interaction (PPI) network). We present a detailed taxonomy of these methods, and comprehensively evaluate them for protein complex identification across a variety of scenarios including the absence of many true interactions and the presence of false-positive interactions (noise) in PPI networks. Based on this evaluation, we highlight challenges faced by the methods, for instance in identifying sparse, sub-, or small complexes and in discerning overlapping complexes, and reveal how a combination of strategies is necessary to accurately reconstruct the entire complexosome.

Silver Bullets - How Interoperable Data Will Revolutionize Information Sharing and Transparency (Hardcover): Pete O'Dell Silver Bullets - How Interoperable Data Will Revolutionize Information Sharing and Transparency (Hardcover)
Pete O'Dell
R917 Discovery Miles 9 170 Ships in 18 - 22 working days

Silver Bullets isn't about understanding the technology of standard, interoperable data; it's about why the technology is important and how you can use it. If you care about effective operations, no matter your job title, this book is for you. Interoperable data is a major game changer for business and information technology, government and commercial, national and international organizations. This book will let you make it happen, versus wondering what happened and how you were left behind. As Frederick Brooks famously noted in The Mythical Man-Month: Essays on Software Engineering, there is no single-approach solution - no Silver Bullet - that delivers significant improvements in productivity, reliability, or simplicity. But in Silver Bullets, Pete O'Dell shows how a single concept - standardized data interoperability - yields improvements in any industry to which it is applied. O'Dell builds his case by reviewing the past. From the Great Wall of China to shipping containers, from punched cards to the VISA network, standardization has fueled enormous breakthroughs. O'Dell investigates current data standardization including XML and the Common Alerting Protocol, using case studies to illustrate success stories ranging from homeland defense to diabetes management. Finally, O'Dell offers practical suggestions on how to get started with interoperable data and points to emerging leaders in commercial, governmental and not-for-profit fields. This accessible, plain-spoken book is full of parables, anecdotes and stories, delivering humor as well as insight. Reading it enables you to make practical decisions about your organization's future and growth. Silver Bullets shines a clear light into your inoperable future.
