The importance of real-time pattern recognition in streaming media is rapidly growing (Liu, Wang, & Chen, 1998). Extracting information from audio and video streams in an e-collaboration scenario is getting increasing relevance as the networking infrastructure develops. This development enables the use of rich media content. Shared archives of this kind of knowledge need tools for exploration, ...

functional response, as describing the rates of predation in different prey density, and determining the predator efficiency, is important in the regulation of prey populations. the functional response of male and female adult of lady beetle, hippodamia variegata, was studied at different densities of green peach aphid under laboratory conditions on canola brassica napus l. (cv. rgs003). nymphs...

In sub-micron processes, resistive path defects are increasingly contributing to the yield loss and the customer fail pareto. Data has been collected on a series of ASIC products and compares the effectiveness of full vector set transition delay fault tests with reduced vector sets, minVDD, customer functional tests and customers system fails. Results show that fault models do not predict the d...

Autonomous intelligent robotic systems that can survive in dynamic changing environments have yet to be realized. The robot must process incoming information, make decisions, and learn from previous actions concurrently and in real time. Reliance on one all-encompassing system with one overburdened processor, no matter how fast, makes this goal unreachable. One of the primary reasons the goal i...

Similarity searching finds application in a wide variety of domains including multilingual databases, computational biology, pattern recognition and text retrieval. Similarity is measured in terms of a distance function (edit distance) in general metric spaces, which is expensive to compute. Indexing techniques can be used reduce the number of distance computations. We present an analysis of va...

In RFID-assisted applications, the customers often request to provide tag searching service determine which specific tags are present in system. practice, usually divided into different groups represent categories or brands. We found that traditional protocols not very appropriate for multi-group RFID scenarios because they cannot ensure results of each group satisfy predefined reliability requ...

Combinatorial auctions are promising auction formats for industrial and public procurement. Potential advantages of using combinatorial auctions include lower overall spend, low transaction costs for multi-item negotiations, fairness and market transparency for suppliers, as well as high allocative efficiency. A number of fundamental design considerations are relevant to the application of comb...

Immune responses are based on the coordinated searching behaviors of immunocytes that are aimed at tracking down specific targets. The search efficiency of immunocytes significantly affects the speed of initiation and development of immune responses. Previous studies have shown that not only the intermittent walk but also the zigzag turning preference of immunocytes contributes to the search ef...

Searching and Browsing on E-commerce Sites: Frequency, Efficiency and Rationale

We develop a theoretical framework on the mechanism of combinatorial binding of transcription factors (TFs) with their specific binding sites on DNA. We consider three possible mechanisms viz. monomer, hetero-oligomer and coordinated recruitment pathways. In the monomer pathway, combinatorial TFs search for their targets in an independent manner and the protein-protein interactions among them w...
