In this project, we work towards a continuous and spatial extension of stochastic π calculus. The continuous semantics is a useful alternative to the discrete semantics and has been recently provided for other process algebras. Ability to express spatial properties of the models is an important practical extension, specially in Systems Biology. Inspired by previous work [7][20], after showing r...

CreditRisk+ is an influential and widely implemented model of portfolio credit risk. As a close variant of models long used for insurance risk, it retains the analytical tractability for which the insurance models were designed. Value-at-risk can be obtained via a recurrence-rule algorithm, so Monte Carlo simulation can be avoided. Little recognized, however, is that the algorithm is fragile. U...

We present a method to accelerate line-ofsight computation for computer generated forces (CGF) using graphics processing units (GPUs). GPUs have become commodity processors and they are part of every game console or PC system. Moreover, their performance has been increasing at a rate faster than CPUs and the trend is expected to continue in the foreseeable future. We present a hybrid algorithm ...

The United Kingdom (UK) Ministry of Defence’s (MOD) Defence Science and Technology Laboratory (Dstl) have sponsored two key development activities relating to the OneSAF Computer Generated Forces (CGF) system and development of a Common Chemical, Biological and Radiological (CBR) modelling capability. The first is an interface to enable OneSAF to operate in a High Level Architecture (HLA) 1516-...

Classification is one of the most important task in application areas of artificial neural networks (ANN).Training neural networks is a complex task in the supervised learning field of research. The main difficulty in adopting ANN is to find the most appropriate combination of learning, transfer and training function for the classification task. We compared the performances of three types of tr...

A weighted version of Lindley Distribution has been presented in this paper, offering a new single-parameter lifetime distribution. The expressions for the moment generating function (mgf), cumulant (cgf), characteristic function, moments, reliability and hazard rate functions distribution have also obtained. Tierney Kadane approximation method used to derive Bayes estimators its parameter (θ),...
