To address the problems of poor adaptability to pulse loss, susceptibility interfered pulses, and need sub-PRI (Pulse Repetition Interval) ranking in existing signal sorting algorithms, this paper proposes an algorithm for staggered PRI signals based on congruence transform. According analysis characteristics signal, proposed transforms arrival time a fixed value, which sequence extraction can ...

We study the stable marriage problem in a distributed environment, in which there are 2n players, n men and n women, each holding a private ranking of the n persons of the opposite set, and there is a server who communicates with the players and finds a matching for them. We restrict our attention on two communication models: the sketch model and the query model. In the sketch model, each playe...

Hemoglobin is a tetrameric oxygen transport protein in animal bodies. However, there is a paucity of information regarding differences between alpha and beta subunits of hemoglobin in terms of oxygen affinity. The sequential model of Koshland, Nemthy and Filmer (KNF model) has attributed similar affinities to both alpha and beta subunits. The main purpose of the present study is to construct a ...

We describe our approach and results towards the Hyperlinking sub-task at MediaEval 2012. We approached this as an Information Retrieval task and used re-ranking strategies for finding relevant videos. A three-step approach was then applied on results to extract the most relevant part of the video regarding the query content. Our results show that reranking strategies and integration of metadat...
