A method of measuring impulse responses of rooms will be described which uses time reversed electronic reverberation from a single pulse as the excitation. The room response, recorded on DAT, is decoded by playing the tape back through the reverberator. The output can be heard, recorded, or analyzed. The method improves S/N by 20 dB and can be implemented with approximately 14 multiples/sample ...

This paper presents convergence acceleration, a method for computing efficiently the limit of numerical sequences as a typical application of streams and higher-order functions.

A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...

This paper presents a new guided image completion method which fills any missing values by considering information from a guidance image. We develop a confidence propagation scheme that allows the filling process to be carried out globally without the need of deciding the filling order. We conduct experiments in several applications where the problem can be formulated into a guided image comple...

In this paper, A modi£cation of the Homotopy analysis method (HAM) applied to nonlinear Riccati differential equations which yields a series solution with accelerated convergence, has been presented. Illustrative examples have been given .

We present an algorithm animation system, Xaa, which is tailored for string algorithms, and, in general, to algorithms that have as input one or two dimensional sequences of symbols. This system provides data generation tools and statistics of the algorithm's behavior.

A novel reconfigurable hardware accelerator speeds the processing of applications based on the MapReduce programming framework.

We discuss some linear acceleration methods for alternating series which are in theory and in practice much better than that of Euler-Van Wijngaarden. One of the algorithms, for instance, permits one to calculate P (?1) k a k with an error of about 17:93 ?n from the rst n terms for a wide class of sequences fa k g. Such methods are useful for high precision calculations frequently appearing in ...
