We consider the e cient solution of partial di↵erential equations for strongly elliptic operators with constant coe cients and stochastic Dirichlet data by the boundary integral equation method. The computation of the solution’s twopoint correlation is well understood if the two-point correlation of the Dirichlet data is known and su ciently smooth. Unfortunately, the problem becomes much more ...

Multi-FPGA boards are being used for logic emulation, rapid prototyping, custom computing and low volume subsystem implementation. A key feature which characterizes these boards is their routing architecture(RA). Inter-FPGA connections in an RA can be of two types, namely fixed connections through direct wires and programmable connections through intermediate Field-Programmable Interconnect Dev...

A novel Non-negative Matrix Factorization (NMF) based subband decomposition in frequency-spatial domain for acoustic source localization using a microphone array. The proposed method decomposes source and noise subband and emphasizes source dominant frequency bins for more accurate source representation. By employing NMF, we extract Delay Basis Vectors (DBV) and their subband information in fre...

The principal objective of this research is to reduce the elapsed time of largescale nonlinear dynamic structural finite element analysis using parallel computing techniques. The major tasks and contributions of this research are: (a) employing the general sparse matrix technique to reduce the computing time and storage requirements for both sequential and parallel substructure analysis (b) emp...

In order to meet the requirements of high-precision positioning for autonomous underwater vehicles (AUVs) in complex and time-varying marine environments, a novel partitioned matrix-based parameter update method embedded variational Bayesian (PMPU-VB) is proposed deal with accuracy problem caused by inaccurate predicted error covariance measurement noise matrices. By employing (VB) method, accu...

A linear matrix inequality (LMI) based criterion for the global asymptotic stability of discrete-time systems with multiple state-delays employing saturation nonlinearities is presented. Numerical examples highlighting the effectiveness of the proposed criterion are given.
