Nowadays, there are several programming languages, which are found to be difficult for a novice programmer to understand. According to Robins [RRR03], students have often difficulties in building mental model of computer programs, since a programming language differs from the structure of natural language. Even when the students have learned the programming concepts and languages, they may stil...

We report on the design and implementation of an extensible programming language and its intrinsic support for formal verification. Our language is targeted at low-level programming of infrastructure like operating systems and runtime systems. It is based on a cross-platform core combining characteristics of assembly languages and compiler intermediate languages. From this foundation, we take l...

reFLe t is a new fun tional language, developed at Intel for use in hardware design and veri ation. It ontains features intended to fa ilitate the onstru tion, analysis, and manipulation of the language's own programs. It is also intended to be the exe utable subset of the term language of a theorem prover based on higher order logi . In this paper, we onsider ore reFLe t|a language that extend...

Word segmentation is an important task in natural language processing, especially for languages without word boundaries, such as Thai language. Many Thai word segmentation programs have been developed. Researchers and developers in Thai documents usually spend a tremendous amount of time in studying and trying different Thai word segmentation programs. This paper presents the performance of six...

With the developments of new technologies appearing very quickly, the attention has been focused more on technology than learning. English centers and institutes have mostly been busy accommodating new programs and technologies and hence have not spent enough time to evaluate the CALL programs and technologies employed to find their affordances and limitations. The present study was an attempt ...

Many software maintenance problems are caused by using text editors to change programs. A more systematic and reliable way of performing program updates is to express changes with an update language. In particular, updates should preserve the syntaxand typecorrectness of the transformed object programs. We describe an update calculus that can be used to update lambdacalculus programs. We develo...

Euclid is a language for writing system programs that are to be verified. We believe that verification and reliability are closely related, because if it is hard to reason about programs using a language feature, it will be diff icult to write programs that use it properly. This pape, discusses a number of issues in the design of Euclid, including such topics as the scope of names, aliasing, mo...

Relative debugging is a technique which addresses the problem of debugging programs developed using evolutionary software techniques. Recent developments allow relative debugging to be used on programs that have been ported from serial to parallel architectures. Such programs may change significantly in the porting process, and this raises many issues for the debugging process. This paper exami...

As the interest for formal methods grows within industry, the need for convenient and automated tools grows too. SOSSubC is an attempt to help the development of certified programs. It allows formal reasoning about imperative programs by translating programs written in SubC, a simple imperative language, into equations. Programs are then axioms of a logical system within which proofs can be car...

Bulk synchronous parallelism (BSP) offers an abstract and simple model of parallelism yet allows to take realistically into account the communication costs of parallel algorithms. BSP has been used in many application domains. BSPlib and its variants are programming libraries for the C language that support the BSP style. Bulk Synchronous Parallel ML (BSML) is a library for BSP programming with...
