This book was released on 2016-03-02 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational perspective on partial order and lattice theory, focusing on algorithms and their applications This book provides a uniform treatment of the theory and applications of lattice theory. The applications covered include tracking dependency in distributed systems, combinatorics, detecting global predicates in distributed systems, set families, and integer partitions. The book presents algorithmic proofs of theorems whenever possible. These proofs are written in the calculational style advocated by Dijkstra, with arguments explicitly spelled out step by step. The author’s intent is for readers to learn not only the proofs, but the heuristics that guide said proofs. Introduction to Lattice Theory with Computer Science Applications: Examines; posets, Dilworth’s theorem, merging algorithms, lattices, lattice completion, morphisms, modular and distributive lattices, slicing, interval orders, tractable posets, lattice enumeration algorithms, and dimension theory Provides end of chapter exercises to help readers retain newfound knowledge on each subject Includes supplementary material at www.ece.utexas.edu/~garg Introduction to Lattice Theory with Computer Science Applications is written for students of computer science, as well as practicing mathematicians.

Download or read book On the feasibility of multi leader replication in the early tiers written by Jungnickel, Tim and published by Universitätsverlag der TU Berlin. This book was released on 2018-09-27 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In traditional service architectures that follow the service statelessness principle, the state is primarily held in the data tier. Here, service operators utilize tailored storage solutions to guarantee the required availability; even though failures can occur at any time. This centralized approach to store and process an application’s state in the data tier implies that outages of the entire tier cannot be tolerated. An alternative approach, which is in focus of this thesis, is to decentralize the processing of state information and to use more stateful components in the early tiers. The possibility to tolerate a temporary outage of an entire tier implies that the application’s state can be manipulated by the remaining tiers without waiting for approval from the unavailable tier. This setup requires multi-leader replication, where every replica can accept writes and forwards the resulting changes to the other replicas. This thesis explores the feasibility of using multi-leader replication to store and process state in a decentralized manner across multiple tiers. To this end, two replication mechanisms, namely Conflict-free Replicated Data Types and Operational Transformation, are under particular investigation. We use and extend both mechanism to demonstrate that the aforementioned decentralization is worth considering when designing a service architecture. The challenges that arise when following our approach go back to fundamental impossibility results in distributed systems research, i.e. the impossibility to achieve a fault-tolerant consensus mechanism in asynchronous systems and the inevitable trade-off between availability and consistency in the presence of failures. With this thesis, we contribute to close the exposed gaps of both results by providing usable alternatives for standard IT services. We exemplify the feasibility of our alternatives with a fully distributed IMAP service and a programming library that provides the necessary extension to utilize our approach in a variety of web-based applications. All contributions of this thesis are based on both theory and practice. In particular, all extensions to the existing multi-leader replication mechanisms were proven to satisfy the necessary properties. Moreover, those extensions were also implemented as prototypical applications and evaluated against the corresponding de facto standard software from the industry. Basierend auf dem “service statelessness principle” ist es üblich, Softwaredienste so zu entwerfen, dass der Zustand des Dienstes primär in einer gekapselten Datenschicht verarbeitet wird. Innerhalb der Datenschicht werden spezielle Lösungen verwendet, um die Verfügbarkeit der Daten sicherzustellen. Dieser zentralisierte Ansatz hat zur Folge, dass ein Ausfall oder eine temporäre Nichtverfügbarkeit der gesamten Datenschicht zwangsweise zur Nichtverfügbarkeit des gesamten Dienstes führt. Ein alternativer Ansatz, welcher in dieser Arbeit erforscht wird, ist die dezentralisierte Speicherung und Verarbeitung der Daten in den darüberliegenden Softwareschichten. Um in diesem Ansatz einen Ausfall der gesamten Datenschicht zu kompensieren, ist es zwingend notwendig, dass die verbleibenden Schichten die eingehenden Anfragen ohne die Bestätigung durch die Datenschicht beantworten können. Hierfür wird eine Replikationsarchitektur benötigt, in der jedes Replikat die Anfragen direkt beantworten kann; die so genannte “multi-leader replication”. In dieser Arbeit werden diese Replikationsarchitekturen verwendet, um den Zustand und die Daten eines Dienstes zu dezentralisieren und über mehrere Schichten zu replizieren. Hierbei werden zwei Mechanismen detaillierter betrachtet: “Conflict-free Replicated Data Types” und “Operational Transformation”. Anschließend werden beide Mechanismen erweitert und hinsichtlich der Verwendbarkeit für den beschriebenen Ansatz geprüft. Als Ergebnis dieser Arbeit wird gezeigt, dass ein dezentralisierter Ansatz mit den vorgestellten Mechanismen in Betracht gezogen werden kann. Die Herausforderungen, die bei der Anwendung dieses Ansatzes entstehen, basieren auf nachweislich unlösbaren Problemen aus der Forschung von Verteilten Systemen. Dazu gehört die Unlösbarkeit von Konsensus und die unausweichliche Abwägung zwischen Verfügbarkeit und Konsistenz in einem verteilten System mit Ausfällen. Diese Arbeit trägt dazu bei, die entstehenden Lücken, welche aus diesen fundamentalen Ergebnissen resultieren, zu schließen und die vorgeschlagenen Lösungen für reale IT Dienste anwendbar zu machen. Dieses wird anhand eines dezentralen IMAP Dienstes und einer Programmierbibliothek für Webanwendungen verdeutlicht. Alle Bestandteile dieser Doktorarbeit verbinden Theorie und Praxis. Alle vorgeschlagenen Erweiterungen für bestehende Replikationssysteme werden in formalen Modellen verifiziert und prototypisch implementiert. Die Implementierungen werden außerdem mit vergleichbarer Standardsoftware, welche dem heutigen Stand der Technik entspricht, in praktischen Experimenten evaluiert.

Download or read book Parts of a Whole written by Lucas Champollion and published by Oxford University Press. This book was released on 2017-03-09 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran all the way to the store for five minutes? Why is five pounds of books acceptable, but *five pounds of book not acceptable? What prevents us from saying *sixty degrees of water to express the temperature of the water in a swimming pool when sixty inches of water can express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.

Download or read book Introduction to Lattices and Order written by B. A. Davey and published by Cambridge University Press. This book was released on 2002-04-18 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Introduction to Lattices and Order presents a radical reorganization and updating, though its primary aim is unchanged. The explosive development of theoretical computer science in recent years has, in particular, influenced the book's evolution: a fresh treatment of fixpoints testifies to this and Galois connections now feature prominently. An early presentation of concept analysis gives both a concrete foundation for the subsequent theory of complete lattices and a glimpse of a methodology for data analysis that is of commercial value in social science. Classroom experience has led to numerous pedagogical improvements and many new exercises have been added. As before, exposure to elementary abstract algebra and the notation of set theory are the only prerequisites, making the book suitable for advanced undergraduates and beginning graduate students. It will also be a valuable resource for anyone who meets ordered structures.

Download or read book Mathematical Methods in Linguistics written by Barbara B.H. Partee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elementary set theory accustoms the students to mathematical abstraction, includes the standard constructions of relations, functions, and orderings, and leads to a discussion of the various orders of infinity. The material on logic covers not only the standard statement logic and first-order predicate logic but includes an introduction to formal systems, axiomatization, and model theory. The section on algebra is presented with an emphasis on lattices as well as Boolean and Heyting algebras. Background for recent research in natural language semantics includes sections on lambda-abstraction and generalized quantifiers. Chapters on automata theory and formal languages contain a discussion of languages between context-free and context-sensitive and form the background for much current work in syntactic theory and computational linguistics. The many exercises not only reinforce basic skills but offer an entry to linguistic applications of mathematical concepts. For upper-level undergraduate students and graduate students in theoretical linguistics, computer-science students with interests in computational linguistics, logic programming and artificial intelligence, mathematicians and logicians with interests in linguistics and the semantics of natural language.
