Improving the frequency precision by synchronizing a lattice of N oscillators with disparate frequencies is studied in the phase reduction limit. In the general case where the coupling is not purely dissipative the synchronized state consists of targetlike waves radiating from a local source, which is a region of higher-frequency oscillators. In this state the improvement of the frequency preci...

A method of relative location for explosions using Rayleigh waves is developed and tested. It involves cross correlating a wavetrain with a previously recorded signal from the same source region and &?.t&mining a relative "travel-time" from the peak in the -ross correlation trace. Locations are fairly accurate, but do not compare with the precision obtained with body waves and relative travel-t...

Transcranial Magnetic Stimulation (TMS) applying magnetic stimulation directly on neurons of the brain noninvasively is being used to treat stroke, Parkinson’s disease, depression, and so on. TMS can provide treatment through more effective stimulation when accurate stimulation is applied to an anatomical position of the patient. So a navigation system for obtaining accurate information about l...

We address the problem of inducing word alignment for language pairs by developing an unsupervised model with the capability of getting applied to other generative alignment models. We approach the task by: i) proposing a new alignment model based on the IBM alignment model 1 that uses vector representation of words, and ii) examining the use of similar source words to overcome the problem of r...

sink location is considered as a basic service in geographic routing in wireless sensor networks. obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. in this paper, a sink location algorithm based on fano plane is proposed. the research challenge is how to ensure the intersection of two slq and sla rou...
