In data analysis and signal processing, the recovery of structured functions from given sampling values is a fundamental problem. Many methods generalized Prony method have been developed to solve this problem; however, current research mainly deals with represented in sparse expansions using single generating function. paper, we generalize expansion problem for two functions, so that more type...

We introduce a numerical method and python package, chimes, that simulates quantum systems initially well approximated by mean field theory using second order extension of the classical approach. call this moment expansion method. In way, we can accurately approximate evolution first moments beyond where breaks down. This allows us to estimate break time approximation without any calculations e...

web search engines are one of the most popular tools on the internet which are widely-used by expert and novice users. constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. query expansion is a way to reduce this concern and increase user satisfaction. in this paper, a new method of query expa...
