Download or read book Regional Failure Events in Communication Networks written by Balázs Vass and published by Springer Nature. This book was released on 2022-08-31 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive study covering the design and application of models and algorithms for assessing the joint device failures of telecommunication backbone networks caused by large-scale regional disasters. At first, failure models are developed to make use of the best data available; in turn, a set of fast algorithms for determining the resulting failure lists are described; further, a theoretical analysis of the complexity of the algorithms and the properties of the failure lists is presented, and relevant practical case studies are investigated. Merging concepts and tools from complexity theory, combinatorial and computational geometry, and probability theory, a comprehensive set of models is developed for translating the disaster hazard in informative yet concise data structures. The information available on the network topology and the disaster hazard is then used to calculate the possible (probabilistic) network failures. The resulting sets of resources that are expected to break down simultaneously are modeled as a collection of Shared Risk Link Groups (SRLGs), or Probabilistic SRLGs. Overall, this book presents improved theoretical methods that can help predicting disaster-caused network malfunctions, identifying vulnerable regions, and assessing precisely the availability of internet services, among other applications.

This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IMA Volume in Mathematics and its Applications DISCRETE EVENT SYSTEMS, MANUFACTURING SYSTEMS AND COMMUNICATION NETWORKS is based on the proceedings of a workshop that was an integral part of the 1992-93 IMA program on "Control Theory. " The study of discrete event dynamical systems (DEDS) has become rapidly popular among researchers in systems and control, in communication networks, in manufacturing, and in distributed computing. This development has created problems for re searchers and potential "consumers" of the research. The first problem is the veritable Babel of languages, formalisms, and approaches, which makes it very difficult to determine the commonalities and distinctions among the competing schools of approaches. The second, related, problem arises from the different traditions, paradigms, values, and experience that scholars bring to their study of DEDS, depending on whether they come from control, com munication, computer science, or mathematical logic. As a result, intellectual exchange among scholars becomes compromised by unexplicated assumptions. The purpose of the Workshop was to promote exchange among scholars representing some of the major "schools" of thought in DEDS with the hope that (1) greater clarity will be achieved thereby, and (2) cross-fertilization will lead to more fruitful questions. We thank P. R. Kumar and P. P. Varaiya for organizing the workshop and editing the proceedings. We also take this opportunity to thank the National Science Foundation and the Army Research Office, whose financial support made the workshop possible. A vner Friedman Willard Miller, Jr.

Download or read book Distributed Model Predictive Control with Event Based Communication written by Groß, Dominic and published by kassel university press GmbH. This book was released on 2015-02-25 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, several algorithms for distributed model predictive control over digital communication networks with parallel computation are developed and analyzed. Distributed control aims at efficiently controlling large scale dynamical systems which consist of interconnected dynamical systems by means of communicating local controllers. Such distributed control problems arise in applications such as chemical processes, formation control, and control of power grids. In distributed model predictive control the underlying idea is to solve a large scale model predictive control problem in a distributed fashion in order to achieve faster computation and better robustness against local failures. Distributed model predictive control often heavily relies on frequent communication between the local model predictive controllers. However, a digital communication network may induce uncertainties such as a communication delays, especially if the load on the communication network is high. One topic of this thesis is to develop a distributed model predictive control algorithm for subsystems interconnected by constraints and common control goals which is robust with respect to time-varying communication delays.

Download or read book Event Triggered and Time Triggered Control Paradigms written by Roman Obermaisser and published by Springer Science & Business Media. This book was released on 2006-01-27 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Event-Triggered and Time-Triggered Control Paradigms presents a valuable survey about existing architectures for safety-critical applications and discusses the issues that must be considered when moving from a federated to an integrated architecture. The book focuses on one key topic - the amalgamation of the event-triggered and the time-triggered control paradigm into a coherent integrated architecture. The architecture provides for the integration of independent distributed application subsystems by introducing multi-criticality nodes and virtual networks of known temporal properties. The feasibility and the tangible advantages of this new architecture are demonstrated with practical examples taken from the automotive industry. Event-Triggered and Time-Triggered Control Paradigms offers significant insights into the architecture and design of integrated embedded systems, both at the conceptual and at the practical level.

Download or read book Spaces and Places in Central and Eastern Europe written by Gyula Horváth and published by Routledge. This book was released on 2014-08-21 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across Europe there is a rapidly changing context for undertaking regional development. In the 20th century, development of the former planned economies (Bulgaria, Czech Republic, Hungary, Poland, Romania and Slovakia), was defined by these countries differences, rather than their common ideological roots. These disparities altered over time and were marked by changing social structures. However, the ranking of regions has remained the same as core areas have strengthened their positions while the structural obstacles to the modernisation of peripheral areas have remained due to a lack of coherent regional policy. This book examines the specific regional development paths of Central and Eastern European countries and evaluates the effects of the determining factors of this process. Through analysis of the system of objectives, instruments and institutions used in different eras, and case studies of Hungary, East Germany and Germany, development models are established and compared with Western European patterns. The book summarises the experiences of Central and Eastern European regional cooperation and examines the basic nature of the cohesion problems of the Carpathian Basin trans-national macro region. It confirms by comparative historical analyses that the transformation was indeed unique. This book will make a welcome addition to the literature for students and academics interested in the broader picture of Central and Eastern European politics, future integration within the European Union and the history of regional development processes.
