A GOOD translation of a novel requires many qualities from the translator. He must be a native speaker or have at least native-like command of the language into which he translates, the target language; he must have a good knowledge of the language from which he translates, the source language, and preferably have lived among the people who habitually speak the source language; he must have som...

We consider software verification of imperative programs by theorem proving in higher-order separation logic. Of particular interest are the difficulties of encoding and reasoning about sharing and aliasing in pointer-based data structures. Both of these are difficulties for reasoning in separation logic because they rely, fundamentally, on non-separate heaps. We show how sharing can be achieve...

abstract quantitative analysis of production through evaluating the level of factor usage is a major part in agricultural management, which aims at increasing production by optimum usage of resources. this study has estimated and analyzed stochastic frontier production function and calculated technical efficiency of semi-mechanized broiler farms located in gorgan district. the survey data were ...

There is a growing interest in the integration of mechanized reasoning systems such as automated theorem provers, computer algebra systems, and model checkers. State-of-the-art reasoning systems are the result of many man-years of careful development and engineering, and usually they provide a high degree of sophistication in their respective domain. Yet they often perform poorly when applied o...

Consider two abstract machines abc and def (described using B notation below). Both models represent the addition of two natural numbers. The second, however, introduces the limitation that, when implemented on a computer, the set of natural numbers cannot be infinite. It is felt that both of these models are needed within a development. The first for use at the abstract level when describing s...

We can adapt existing techniques for the statistical modeling of music to the modeling of the quality of musical performance, resulting in a fine-grained statistical understanding of ’hardness’ in music performance. This drives AI-assisted applications for improving skill. We present modeling results using various probabilistic models to model performance in the simplified setting of rhythm games.

Proof assistants and the programming languages that implement them need to deal with a range of linguistic expressions that involve bindings. Since most mature proof assistants do not have built-in methods to treat this aspect of syntax, they have been extended with various packages and libraries that allow them to encode such syntax using, for example, de Bruijn numerals and nominal logic feat...

Over a decade ago, the POPLmark challenge [2] suggested that the theorem proving community had tools that were close to being usable by programming language researchers to formally prove properties of their designs and implementations. The authors of the POPLmark challenge looked at existing practices and systems and urged the developers of proof assistants to make improvements to existing syst...

As many others, we too are developping a Massive Online Open Course or MOOC. This MOOC will teach recursive programming to beginners and will heavily use an already existing infrastructure for mechanical grading (Queinnec, 2010). This position paper discusses how these two components are combined in order to increase students’ involvement. Developping a MOOC is now a common activity in the Acad...
