Model Checking for Programming Languages using VeriSoft

by Patrice Godefroid - IN PROCEEDINGS OF THE 24TH ACM SYMPOSIUM ON PRINCIPLES OF PROGRAMMING LANGUAGES , 1997
"... Verification by state-space exploration, also often referred to as "model checking", is an effective method for analyzing the correctness of concurrent reactive systems (e.g., communication protocols). Unfortunately, existing model-checking techniques are restricted to the verification of ..."

of properties of models, i.e., abstractions, of concurrent systems. In this paper, we discuss how model checking can be extended to deal directly with "actual" descriptions of concurrent systems, e.g., implementations of communication protocols written in programming languages such as C or C++. We

Formal Languages

by Ning Yu , 1973
"... Close to 30 percent of all patents are chemical patents, of which roughly 10 percent claim IP rights over novel chemical structures using the Markush notation[1-5]. An example of an approved patent with claims on a series of 4-anilino-3-quinolinecarbonitriles-based chemical structures for the ..."

An Overview of the C++ Programming Language

by Bjarne Stroustrup , 1999
"... This overview of C++ presents the key design, programming, and language-technical concepts using examples to give the reader a feel for the language. C++ is a general-purpose programming language with a bias towards systems programming that supports efficient low-level computation, data abstraction, ..."

The Ponder Policy Specification Language

by Nicodemos Damianou , Naranker Dulay , Emil Lupu , Morris Sloman - LECTURE NOTES IN COMPUTER SCIENCE , 2001
"... The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management ..."

of networks and distributed systems. Ponder can also be used for security management activities such as registration of users or logging and auditing events for dealing with access to critical resources or security violations. Key concepts of the language include roles to group policies relating to a position

The Lorel Query Language for Semistructured Data

by Serge Abiteboul, Dallan Quass, Jason Mchugh, Jennifer Widom, Janet Wiener - International Journal on Digital Libraries , 1997
"... We present the Lorel language, designed for querying semistructured data. Semistructured data is becoming more and more prevalent, e.g., in structured documents such as HTML and when performing simple integration of data from multiple sources. Traditional data models and query languages are inapprop ..."

are inappropriate, since semistructured data often is irregular, some data is missing, similar concepts are represented using different types, heterogeneous sets are present, or object structure is not fully known. Lorel is a user-friendly language in the SQL/OQL style for querying such data effectively. For wide

The synchronous dataflow programming language LUSTRE

by N. Halbwachs, P. Caspi, P. Raymond, D. Pilaud - Proceedings of the IEEE , 1991
"... This paper describes the language Lustre, which is a dataflow synchronous language, designed for programming reactive systems --- such as automatic control and monitoring systems --- as well as for describing hardware. The dataflow aspect of Lustre makes it very close to usual description tools in t ..."
Abstract - Cited by 646 (50 self) - Add to MetaCart
formalism is very similar to temporal logics. This allows the language to be used for both writing programs and expressing program properties, which results in an original program verification methodology. 1 Introduction Reactive systems Reactive systems have been defined as computing systems which

Principles and Practice in Second Language Acquisition

by Stephen D Krashen , 1982
"... This is the original version of Principles and Practice, as published in 1982, with only minor changes. It is gratifying to point out that many of the predictions made in this book were confirmed by subsequent research, for example, the superiority of comprehensible-input based methods and sheltered ..."

best through comprehensible input (Krashen, 1989; 2003). I have changed my position on only one issue: At the end of Principles and Practice, I suggest the use of a form of deception- students may think they are acquiring vocabulary or learning subject matter, but unknown to them, they are acquiring

The Magma Algebra System I: The User Language

by Wieb Bosma , John Cannon , Catherine Playoust , 1997
"... In the first of two papers on Magma, a new system for computational algebra, we present the Magma language, outline the design principles and theoretical background, and indicate its scope and use. Particular attention is given to the constructors for structures, maps, and sets. ..."

A Maximum Entropy approach to Natural Language Processing

by Adam L. Berger, Stephen A. Della Pietra , Vincent J. Della Pietra - COMPUTATIONAL LINGUISTICS , 1996
"... The concept of maximum entropy can be traced back along multiple threads to Biblical times. Only recently, however, have computers become powerful enough to permit the widescale application of this concept to real world problems in statistical estimation and pattern recognition. In this paper we des ..."

describe a method for statistical modeling based on maximum entropy. We present a maximum-likelihood approach for automatically constructing maximum entropy models and describe how to implement this approach efficiently, using as examples several problems in natural language processing.

The Semantics of Predicate Logic as a Programming Language

by M. H. Van Emden, R. A. Kowalski - JOURNAL OF THE ACM , 1976
"... Sentences in first-order predicate logic can be usefully interpreted as programs In this paper the operational and fixpoint semantics of predicate logic programs are defined, and the connections with the proof theory and model theory of logic are investigated It is concluded that operational seman ..."
