In my view, the “verification problem” is the theorem proving problem, restricted to a computational logic. My approach is: adopt a functional programming language, build a general purpose formal reasoning engine around it, integrate it into a program and proof development environment, and apply it to model and verify a wide variety of computing artifacts, usually modeled operationally within t...

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...

In vitro studies on cancer cell lines still constitutes a major part of cancer research. It is very important that the researchers consider the importance of basic conditions of working with different cell lines. To the best of authors knowledge, this study is the first one to report the effect of seeding density on the growth curve of three human cancer cell lines. These cell lines include hum...

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.

In the 1990s numerous winter orographic cloud seeding experiments were conducted over Utah’s Wasatch Plateau. Several previously published case studies successfully documented the physical response in clouds and precipitation to ground-based seeding with silver iodide and liquid propane. A previously unpublished case study that shows additional evidence of positive seeding effects is presented ...
