Formales SQL-Tuning für Oracle-Datenbanken: Praktische Effizienz - effiziente Praxis (Xpert.press)

by Leonid Nossov Hanno Ernst Victor Chupis

Das Ziel des SQL-Tunings ist eine Verbesserung des bestehenden Ausführungsplans. Die in diesem Buch beschriebene Methode kann man „Bremsenbeseitigung im Ausführungsplan“ nennen. Solche „Bremsen“ oder Engpässe lassen sich durch eine formale Analyse des Ausführungsplans erkennen. Dafür sind keine Datenmodellkentnisse notwendig. Das ist besonders vorteilhaft für Datenbankadministratoren, weil sie in der Regel gar nicht oder unzureichend gut mit dem Datenmodell vertraut sind. Im Buch werden zahlreiche praktische Erfahrungen mit dieser Methode präsentiert.

Formalisieren und Beweisen: Logik für Informatiker (Lehrbuch Informatik)

by Dirk Siefkes

Gregory Bateson -Biologe, Anthropologe, Psychiater, Systemtheoretiker -erzählt in der Ein­ l leitung zu seinem Buch Geist und Natur eine Geschichte: Ein Mann gibt in seinen Computer die Frage ein: "Wirst Du jemals denken wie ein Mensch? Rechne mal nach!" Der Computer rechnet und rechnet und gibt schließlich aus: Dabei fallt mir eine Geschichte ein. Die Geschichte dieses Buches handelt von Menschen. "Fangt doch jeden Abschnitt mit einem Beispiel an", schlug Ralf-Detlef Kutsche vor, als er mir 1982 zusammen mit Peter Padawitz, Simone Pribbenow und Andreas Schulze half, die Lehrveranstaltung Logik für Informatiker durchzuführen. "Fragen und Aufgaben regen besser zum Arbeiten an als Begriffe und Sätze. " Deswegen beginnt jeder Teil dieses Buches mit einer Geschichte, die als Arbeitsmaterial dient: Die Einführung mit dem Problem des Affen mit der Banane, die Aussagenlogik mit der Ballwurf­ logelei, die Offene Prädikatenlogik mit dem Architektenbeispiel und die volle Prädikatenlogik mit der Geometrie Euklids. Deswegen endet jeder Abschnitt mit Aufgaben und Fragen, die wesentlich fürs Verstehen sind. Deswegen sieht man beim Blättern so wenig Beweise: Ich ent­ wickle einen Beweis lieber aus einer Fragestellung und formuliere das Ergebnis als Satz, statt mit dem Satz zu beginnen. Deswegen sind die Themen des Buches Formalisieren und Verstehen, Tätigkeiten, und nicht Logik und Informatik, Gebiete. Ich behandle in dem Buch im wesentlichen die klassischen Grundthemen der mathematischen Logik: logische Folgerung, Ableitung, Vollständigkeit, logische Theorie, Axiomensystem. Es geht mir aber nicht darum, diese Begriffe und ihre Eigenschaften darzustellen.

Formalisms for Reuse and Systems Integration (Advances in Intelligent Systems and Computing #346)

by Thouraya Bouabana-Tebibel Stuart H. Rubin

Reuse and integration are defined as synergistic concepts, where reuse addresses how to minimize redundancy in the creation of components; while, integration focuses on component composition. Integration supports reuse and vice versa. These related concepts support the design of software and systems for maximizing performance while minimizing cost. Knowledge, like data, is subject to reuse; and, each can be interpreted as the other. This means that inherent complexity, a measure of the potential utility of a system, is directly proportional to the extent to which it maximizes reuse and integration. Formal methods can provide an appropriate context for the rigorous handling of these synergistic concepts. Furthermore, formal languages allow for non ambiguous model specification; and, formal verification techniques provide support for insuring the validity of reuse and integration mechanisms. This edited book includes 12 high quality research papers written by experts in formal aspects of reuse and integration to cover the most recent advances in the field. These papers are extended versions of some of the best papers, which were presented at the IEEE International Conference on Information Reuse and Integration and the IEEE International Workshop on Formal Methods Integration - both of which were held in San Francisco in August 2014.

The Formalisms of Quantum Mechanics: An Introduction (Lecture Notes in Physics #893)

by Francois David

These lecture notes present a concise and introductory, yet as far as possible coherent, view of the main formalizations of quantum mechanics and of quantum field theories, their interrelations and their theoretical foundations.The “standard” formulation of quantum mechanics (involving the Hilbert space of pure states, self-adjoint operators as physical observables, and the probabilistic interpretation given by the Born rule) on one hand, and the path integral and functional integral representations of probabilities amplitudes on the other, are the standard tools used in most applications of quantum theory in physics and chemistry. Yet, other mathematical representations of quantum mechanics sometimes allow better comprehension and justification of quantum theory. This text focuses on two of such representations: the algebraic formulation of quantum mechanics and the “quantum logic” approach. Last but not least, some emphasis will also be put on understanding the relation between quantum physics and special relativity through their common roots - causality, locality and reversibility, as well as on the relation between quantum theory, information theory, correlations and measurements, and quantum gravity.Quantum mechanics is probably the most successful physical theory ever proposed and despite huge experimental and technical progresses in over almost a century, it has never been seriously challenged by experiments. In addition, quantum information science has become an important and very active field in recent decades, further enriching the many facets of quantum physics. Yet, there is a strong revival of the discussions about the principles of quantum mechanics and its seemingly paradoxical aspects: sometimes the theory is portrayed as the unchallenged and dominant paradigm of modern physical sciences and technologies while sometimes it is considered a still mysterious and poorly understood theory, waiting for a revolution. This volume, addressing graduate students and seasoned researchers alike, aims to contribute to the reconciliation of these two facets of quantum mechanics.

Formalization of Complex Analysis and Matrix Theory

by Zhiping Shi Yong Guan Ximeng Li

This book discusses the formalization of mathematical theories centering on complex analysis and matrix theory, covering topics such as algebraic systems, complex numbers, gauge integration, the Fourier transformation and its discrete counterpart, matrices and their transformation, inner product spaces, and function matrices. The formalization is performed using the interactive theorem prover HOL4, chiefly developed at the University of Cambridge. Many of the developments presented are now integral parts of the library of this prover.As mathematical developments continue to gain in complexity, sometimes demanding proofs of enormous sizes, formalization has proven to be invaluable in terms of obtaining real confidence in their correctness. This book provides a basis for the computer-aided verification of engineering systems constructed using the principles of complex analysis and matrix theory, as well as building blocks for the formalization of more involved mathematical theories.

Formalizing Data-Centric Web Services (Web-Scale Workflow and Analytics)

by Iman Saleh

This book presents a methodology to model and specify the data aspect of Web services, as it is overlooked by current standards for specifying Web services. The formal specification enables verification of service behavior, and the proposed methodology is based on formal methods and design-by-contract techniques. The Web has evolved from an information sharing medium to a wide-scale environment for sharing capabilities or services. Currently, URLs not only point to documents and images, but are also used to invoke services that potentially change the state of the Web. Major online organizations today, such as Amazon, PayPal and FedEx, provide services for users and consumers. They also allow third-party vendors to resell their services. In both cases, this requires precise and complete specification of service offerings. Several online discussions demonstrate the challenges faced by these organizations and others while describing their data-centric Web services. These challenges surrounding data specification can lead consumers to use a service erroneously. Case studies demonstrate how formal methods, and specifically design-by-contract techniques, can be leveraged to address the lack of formal specification of data when it comes to developing Web applications such as Amazon and PayPal.

Formation and Containment Control for High-order Linear Swarm Systems (Springer Theses)

by Xiwang Dong

This book focuses on analysis and design problems for high-order linear time-invariant (LTI) swarm systems (multi-agent systems) to achieve consensus, formation, containment and formation-containment. As a first step, the concepts of practical consensus and formation-containment are introduced. Unlike previous research, the formation in this book can be time-varying. A general framework for consensus, consensus tracking, formation, containment and state formation-containment is presented for the first time.Sufficient/necessary and sufficient conditions, and approaches to designing the protocols for swarm systems to achieve these control objectives, are respectively proposed. Autonomous time-varying formation experiments using five quadrotor unmanned aerial vehicles (UAVs) are conducted in an outdoor setting to demonstrate the theoretical results.

Formation and Early Growth of Business Webs: Modular Product Systems in Network Markets (Information Age Economy)

by Florian Steiner

Networks of firms have been in the focus of management research for several years. Recently, special attention has been paid to so-called business webs. Business webs are networks of firms which provide complements to a common product architecture. In the past, research focused on management issues of such webs but neglected the important question of how they actually came into being. The present book explicitly examines the formation and early growth of business webs. The author illustrates the early growth phases with two in-depth cases of the formation of the wireless internet ecosystem i-mode and the leading person-to-person online auction platform eBay. The book uncovers the contingencies under which the establishment of business webs is likely to succeed. Business researchers will benefit from the theoretical framework, while interested business managers will find explanations and advice for establishing a business web.

Formation Control: Approaches for Distributed Agents (Studies in Systems, Decision and Control #205)

by Hyo-Sung Ahn

This monograph introduces recent developments in formation control of distributed-agent systems. Eschewing the traditional concern with the dynamic characteristics of individual agents, the book proposes a treatment that studies the formation control problem in terms of interactions among agents including factors such as sensing topology, communication and actuation topologies, and computations. Keeping pace with recent technological advancements in control, communications, sensing and computation that have begun to bring the applications of distributed-systems theory out of the industrial sphere and into that of day-to-day life, this monograph provides distributed control algorithms for a group of agents that may behave together. Unlike traditional control laws that usually require measurements with respect to a global coordinate frame and communications between a centralized operation center and agents, this book provides control laws that require only relative measurements and communications between agents without interaction with a centralized operator. Since the control algorithms presented in this book do not require any global sensing and any information exchanges with a centralized operation center, they can be realized in a fully distributed way, which significantly reduces the operation and implementation costs of a group of agents. Formation Control will give both students and researchers interested in pursuing this field a good grounding on which to base their work.
