We consider network clustering as the way to improve the performance of locating data in unstructured P2P systems. Connectivity-based Distributed node Clustering (CDC), and SCM-based Distributed Clustering (SDC) are two major protocols that allow partitioning a network topology into clusters, based on node connectivity. These protocols focus on the accuracy of the clustering scheme, i.e. using ...

Motion estimation (ME) is one of the most time-consuming parts in video encoding system, and significantly affects the quality of the reconstructed sequences. In this paper, we propose a new fast algorithm, or the Feature Assisted Search Technique for Motion Estimation (FASTME), which is a gradient descent search combined with a new search strategy, namely, one-dimensional feature matching base...

Graphs are prevailingly used in many applications to model complex data structures. In this paper, we study the problem of supergraph containment search. To avoid the NP-complete subgraph isomorphism test, most existing works follow the filtering-verification framework and select graph-features to build effective indexes, which filter false results (graphs) before conducting the costly verifica...

The explosive growth of string databases makes similarity search a challenging problem. Current search tools are non-interactive in the sense that the user has to wait a long time until the entire database is inspected. We consider the problem of interactive searching, and propose a set of innovative -NN ( -Nearest Neighbor) search algorithms. We propose a new model for the distance distributio...

I describe a framework for the presentation of search results which is motivated by frequentist statistics. The most well-known use of this framework is for the combined search for the Higgs boson at LEP. A toy neutrino oscillations experiment is used to illustrate the rich information available in the framework for exclusion and discovery. I argue that the so-called technique for setting limit...

abstract background: in recent years, infrared thermography tools are used for viral disease detection. however, no study has been to evaluate the value of this device. the current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports. materials and methods: this study was conducted as a systematic review. all...
