The proposed research performs the capacity analysis of wireless channel described by fluctuating double-Rayleigh with line-of-sight model. closed-form analytical expressions for conditional (in case arbitrary noninteger fading parameter) and ergodic integer are derived in terms extended generalized bivariate Meijer G-function. exact solutions succeeded approximating deduced cases small large r...

Sparse matrix factorization is a critical step for the circuit simulation problem, since it is time consuming and computed repeatedly in the flow of circuit simulation. To accelerate the factorization of sparse matrices, a parallel CPU+FPGA based architecture is proposed in this paper. While the preprocessing of the matrix is implemented on CPU, the parallelism of numeric factorization is explo...

Military Operations Research makes extensive use of large complex simulation models. These simulation models are often black-boxes; i.e. they are opaque and incomprehensible. A considerable effort is involved in commissioning a new model into service. We characterise this activity as the construction of gray-box approximate causal models of the functional behaviour of black-box simulation softw...

Substantial progress has been made in building and simulating qualitative models . However, the result s of qualitative simulation may be difficult to under stand and programs for explaining them have been fe w and have had a number of limitations . This paper describes a system, Expound, which provides causal natural language explanations of events in provabl y "faithful" abstractions of behav...
