Hardware correctness is becoming ever more important in the design of computer systems. The authors introduce a powerful new approach to the design and analysis of modern computer architectures, based on mathematically well-founded formal methods which allows for rigorous correctness proofs, accurate hardware costs determination, and performance evaluation. This book develops, at the gate level, the complete design of a pipelined RISC processor with a fully IEEE-compliant floating-point unit. In contrast to other design approaches, the design presented here is modular, clean and complete.
Paul Wenz was born in France in 1869, lived in Australia, and wrote stories dealing mainly with his Australian experiences for the French. He wrote ten books from 'Nanima', his homestead in Forbes, New South Wales, including two collections of short stories and four Australian novels. He also translated Jack London and Joseph Conrad, both who came to visit him in Australia. Diary of a New Chum and Other Lost Stories contains many stories never before published in English, and includes correspondence with authors such as Andre Gide, Miles Franklin and Christopher Brennan. Always the very essence of the Australia of Wenz's period, Diary of a New Chum and Other Lost Stories sparkles with irony and psychological insight and represents Paul Wenz at his powerful best.
A richly illustrated guide to the wildflowers and other flora of coastal Britain, Ireland and Northwest Europe The rugged and beautiful coastal regions of Britain and Ireland are among the crowning glories of these islands. Few visitors can fail to marvel at the stunning sight of Cornwall’s clifftops resplendent with flowering Thrift, or be struck by the resilience of plants that thrive on the inhospitable shingle beaches of Dungeness on the coast of Kent. This field guide covers more than 600 species of wildflowers and other coastal flora found in Britain and Ireland, and coastal mainland Northwest Europe. Detailed species accounts describe wildflowers, grasses, sedges and rushes that occur on the coast or in abundance within sight of the sea. Stunningly illustrated throughout, this comprehensive, user-friendly guide also covers trees and shrubs, a range of other groups from mosses and seaweeds, and more broadly, the natural history of coastal habitats. Covers more than 600 species of flowering plantsFeatures over 1,500 spectacular colour photosDescribes other groups such as ferns, mosses, liverworts, lichens, fungi and seaweedsProvides up-to-date colour distribution maps for Britain and Ireland
This volume contains seven synchronic and diachronic empirical investigations into the expression and conceptualization of linguistic action in English, focusing on figurative extensions. The following issues are explored: • Source domains, and their relation to the complexities of linguistic action as a target domain. • The role of axiological parameter, the experiential grounding of metaphors expressing value judgements and the part played by image-schemata, how value judgements come about and their socio-cultural embedding. • The graded character of metaphoricity and its correlation with degrees of recoverability/salience. • The interaction of metonymy and metaphor, e.g. the question what factors motivate the conventionalization of metonymies, which includes the perspective that conventionalized metaphors frequently have a metonymic origin. • The role of image-schemata in the organization and development of a lexical subfield, which raises new questions on the nature of metaphor, the identification of source and target domains and the Invariance Hypothesis.
Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements
The stepwise refinement method postulates a system construction route that starts with a high-level specification, goes through a number of provably correct development steps, and ends with an executable program. The contributions to this volume survey the state of the art in this extremely active research area. The world's leading specialists in concurrent program specification, verification, and the theory of their refinement present latest research results and surveys of the fields. State-based, algebraic, temporal logic oriented and category theory oriented approaches are presented. Special attention is paid to the relationship between compositionality and refinement for distributed programs. Surveys are given of results on refinement in partial-order based approaches to concurrency. A unified treatment is given of the assumption/commitment paradigm in compositional concurrent program specification and verification, and the extension of these to liveness properties. Latest results are presented on specifying and proving concurrent data bases correct, and deriving network protocols from their specifications.
Reading Public Romanticism is a significant new example of the linking of esthetics and historical criticism. Here Paul Magnuson locates Romantic poetry within a public discourse that combines politics and esthetics, nationalism and domesticity, sexuality and morality, law and legitimacy. Building on his well-regarded previous work, Magnuson practices a methodology of close historical reading by identifying precise versions of poems, reading their rhetoric of allusion and quotation in the contexts of their original publication, and describing their public genres, such as the letter. He studies the author's public signature or motto, the forms and significance of address used in poems, and the resonances of poetic language and tropes in the public debates. According to Magnuson, "reading locations" means reading the writing that surrounds a poem, the "paratext" or "frame" of the esthetic boundary. In their particular locations in the public discourse, romantic poems are illocutionary speech acts that take a stand on public issues and legitimate their authors both as public characters and as writers. He traces the public significance of canonical poems commonly considered as lyrics with little explicit social or political commentary, including Wordsworth's "Immortality Ode"; Coleridge's "This Lime-Tree Bower My Prison," "Frost at Midnight," and "The Ancient Mariner"; and Keats's "On a Grecian Urn." He also positions Byron's Dedication to Don Juan in the debates over Southey's laureateship and claims for poetic authority and legitimacy. Reading Public Romanticism is a thoughtful and revealing work. Originally published in 1998. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Uniting dozens of seemingly disparate results from different fields, this book combines concepts from mathematics and computer science to present the first integrated treatment of sequences generated by 'finite automata'. The authors apply the theory to the study of automatic sequences and their generalizations, such as Sturmian words and k-regular sequences. And further, they provide applications to number theory (particularly to formal power series and transcendence in finite characteristic), physics, computer graphics, and music. Starting from first principles wherever feasible, basic results from combinatorics on words, numeration systems, and models of computation are discussed. Thus this book is suitable for graduate students or advanced undergraduates, as well as for mature researchers wishing to know more about this fascinating subject. Results are presented from first principles wherever feasible, and the book is supplemented by a collection of 460 exercises, 85 open problems, and over 1600 citations to the literature.
This monograph is based on the third author's lectures on computer architecture, given in the summer semester 2013 at Saarland University, Germany. It contains a gate level construction of a multi-core machine with pipelined MIPS processor cores and a sequentially consistent shared memory. The book contains the first correctness proofs for both the gate level implementation of a multi-core processor and also of a cache based sequentially consistent shared memory. This opens the way to the formal verification of synthesizable hardware for multi-core processors in the future. Constructions are in a gate level hardware model and thus deterministic. In contrast the reference models against which correctness is shown are nondeterministic. The development of the additional machinery for these proofs and the correctness proof of the shared memory at the gate level are the main technical contributions of this work.
