Lucid, the Dataflow Programming Language


Book Description

Lucid is anew dataflow language, designed to exploit the capabilities of the multi-processor machines which are more powerful than single-processor machines, and require a language in which highly parallel algorithms can be easily expressed. The primary objective of this book is to prove that dataflow is a real alternative to sequential/imperative computing and that dataflow algorithms can be expressed naturally and concisely in Lucid.




Programming Language Implementation and Logic Programming


Book Description

This volume contains the papers which have been accepted for presentation atthe Third International Symposium on Programming Language Implementation andLogic Programming (PLILP '91) held in Passau, Germany, August 26-28, 1991. The aim of the symposium was to explore new declarative concepts, methods and techniques relevant for the implementation of all kinds of programming languages, whether algorithmic or declarative ones. The intention was to gather researchers from the fields of algorithmic programming languages as well as logic, functional and object-oriented programming. This volume contains the two invited talks given at the symposium by H. Ait-Kaci and D.B. MacQueen, 32 selected papers, and abstracts of several system demonstrations. The proceedings of PLILP '88 and PLILP '90 are available as Lecture Notes in Computer Science Volumes 348 and 456.




Multidimensional Programming


Book Description

This book describes a powerful language for multidimensional declarative programming called Lucid. Lucid has evolved considerably in the past ten years. The main catalyst for this metamorphosis was the discovery that Lucid is based on intensional logic, one commonly used in studying natural languages. Intensionality, and more specifically indexicality, has enabled Lucid to implicitly express multidimensional objects that change, a fundamental capability with several consequences which are explored in this book. The author covers a broad range of topics, from foundations to applications, and from implementations to implications. The role of intensional logic in Lucid as well as its consequences for programming in general is discussed. The syntax and mathematical semantics of the language are given and its ability to be used as a formal system for transformation and verification is presented. The use of Lucid in both multidimensional applications programming and software systems construction (such as a parallel programming system and a visual programming system) is described. A novel model of multidimensional computation--education--is described along with its serendipitous practical benefits for harnessing parallelism and tolerating faults. As the only volume that reflects the advances over the past decade, this work will be of great interest to researchers and advanced students involved with declarative language systems and programming.







Programming Languages and Systems


Book Description

This book constitutes the refereed proceedings of the Third Asian Symposium on Programming Languages and Systems, APLAS 2005, held in Tsukuba, Japan in November 2005. The 24 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 78 submissions. Among the topics covered are semantics, type theory, program transformation, static analysis, verification, programming calculi, functional programming languages, language based security, real-time systems, embedded systems, formal systems design, Java objects, program analysis and optimization.




Formal Techniques in Real-Time and Fault-Tolerant Systems


Book Description

This book presents state-of-the-art research results in the area of formal methods for real-time and fault-tolerant systems. The papers consider problems and solutions in safety-critical system design and examine how wellthe use of formal techniques for design, analysis and verification serves in relating theory to practical realities. The book contains papers on real-time and fault-tolerance issues. Formal logic, process algebra, and action/event models are applied: - to specify and model qualitative and quantitative real-time and fault-tolerant behavior, - to analyze timeliness requirements and consequences of faulthypotheses, - to verify protocols and program code, - to formulate formal frameworks for development of real-time and fault-tolerant systems, - to formulate semantics of languages. The integration and cross-fertilization of real-time and fault-tolerance issues have brought newinsights in recent years, and these are presented in this book.




New Trends in Software Methodologies, Tools and Techniques


Book Description

Software is the essential enabler for the new economy and science. It creates new markets and new directions for a more reliable, flexible, and robust society. It empowers the exploration of our world in ever more depth. However, software often falls short behind our expectations. Current software methodologies, tools, and techniques remain expensive and not yet reliable for a highly changeable and evolutionary market. Many approaches have been proven only as case-by-case oriented methods. This book presents a number of new trends and theories in the direction in which we believe software science and engineering may develop to transform the role of software and science in tomorrow’s information society. This publication is an attempt to capture the essence of a new state of art in software science and its supporting technology. Is also aims at identifying the challenges such a technology has to master.




Languages for Developing User Interfaces


Book Description

This book brings together a number of researchers and developers from industry and academia who report on their work. It is of interest to language designers and the creators of toolkits, UIMSs, and other user interface tools.




Distributed Communities on the Web


Book Description

Communities are groupings of distributed objects that are capable of com- nicating, directly or indirectly, through the medium of a shared context. To support communities on a wide scale will require developments at all levels of computing, from low-level communication protocols supporting transparent - cess to mobile objects, through to distributed operating systems, through to high-level programming models allowing complex interaction between objects. This workshop brought together researchers interested in the technical issues of supporting communities. This workshop was the third in the DCW series. The ?rst two, entitled D- tributed Computing on the Web, took place in 1998 and 1999 at the University of Rostock, with proceedings published by the University of Rostock Press. This year, the workshop also incorporated the ISLIP (International Symposium on Languages for Intensional Programming) symposium. The ISLIP symposia have taken place every year since 1988, and have led to two volumes published by World-Scienti?c (Intensional Programming I, 1995, and Intensional Progr- ming II, 2000). While the two conferences emerged from di?erent needs, their focus merged to such an extent that it became clear that a joint conference promised to o?er great opportunities.




Declarative Agent Languages and Technologies II


Book Description

The second edition of the workshop on Declarative Agent Languages and Te- nologies (DALT 2004) was held July 2004 in New York City, and was a great success. We saw a signi?cant increase in both the number of submitted papers and workshop attendees from the ?rst meeting, held July 2003 in Melbourne. Nearly 40 research groups worldwide were motivated to contribute to this event by submitting their most recent research achievements, covering a wide variety of the topics listed in the call for papers. More than 30 top researchers agreed to join the Program Committee, which then collectively faced the hard task of selecting the one-day event program. The fact that research in multi-agent systems is no longer only a novel and promising research horizon at dawn is, in our opinion, the main reason behind DALT’s (still short) success story. On the one hand, agent theories and app- cations are mature enough to model complex domains and scenarios, and to successfully address a wide range of multifaceted problems, thus creating the urge to make the best use of this expressive and versatile paradigm, and also pro?t from all the important results achieved so far. On the other hand, bui- ing multi-agent systems still calls for models and technologies that could ensure system predictability, accommodate ?exibility, heterogeneity and openness, and enable system veri?cation.
