Spatially explicit agent-based models have a great potential to mitigate their computational costs by taking advantage of parallel and high-performance computing. However, the spatial dependency and heterogeneity of interactions pose challenges for parallel SE-ABMs to achieve good scalability. This paper applies the principle of data locality to tackle these challenges by extending a theoretica...

This paper proposes a technique to encourage the interest of students in learning formal methods. Our course is focused on the B method, involving basic knowledge of set theory, invariance proofs, refinement techniques and so on. While lectures and tutorials cover a large range of such concepts, the practical work is focused on applying the principles of a model-based approach in the context of...

In this paper we make use of formal methods and tools as means to specify and reason about the behavior of distributed systems in the presence of faults. The approach used is based on the observation that a fault behavior can be modeled as an unwanted but possible transition of a system. It is then possible to define a transformation of a model M1 of a distributed system into a model M2 represe...

In a Hindi to Bengali transfer based machine translation system the baseline lexical transfer module replaces a Hindi word by its most frequent Bengali translation. Some pronouns in Hindi can have multiple translations in Bengali. The choices of actual translations have big impact on the accessibility of the translated sentence. The list of Hindi pronouns is small and their corresponding Bengal...

In 2003, Augot et al. introduced the Fast Syndrome-Based hash family (in short FSB), which follows the generic construction of Merkle-Damg̊ard and is based on the syndrome decoding problem. In 2007, Finiasz et al. proposed an improved version of FSB. In this work, we propose a new efficient hash function, which incorporates the ideas of FSB and the sponge construction introduced by Bertoni et al...

In this paper we overview one specific approach to the formal development of multi-agent systems. This approach is based on the use of temporal logics to represent both the behaviour of individual agents, and the macro-level behaviour of multi-agent systems. We describe how formal specification, verification and refinement can all be developed using this temporal basis, and how implementation c...

Mobile telephone service was first introduced to Japanese market in the mid-1980s and from then on, this area of business has shown a rapid growth of the number of the subscribers. However, recently, the mobile telephone market in Japan has become saturated. Most of the adult populations have at least one mobile phone set nowadays. Moreover, there are hardly any distinct differences in the qual...

in this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. the conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. this study evaluates the advantages of using the integral form of the equations in the...

Despite decades of research, the takeup of formal methods for developing provably correct software in industry remains slow. One reason for this is the high cost of proof construction, an activity that, due to the complexity of the required proofs, is typically carried out using interactive theorem provers. In this paper we propose an agent-oriented architecture for interactive theorem proving ...
