Information retrieval is a fundamental component of human information behavior. The ability to extract useful information from large electronic resources not only is one of the main activities of individuals online but is an essential skill for most professional groups and a means of achieving competitive advantage. Our electronic information world is becoming increasingly complex with more sou...

The goal of this paper is to propose the performance evaluation of the scaling of parallel software for biological sequence alignment and homology searching based on blast algorithm for sequence searching and clustalw algorithm for multiple sequence alignment on the supercomputer BlueGene/P for the case study of influenza virus sequences variability and homology searching with human genome.

Misperception is defined as wrong beliefs, which are generated when an individual receives or processes information. Misperception has been assumed to be harmful in general. However, misperception can be adaptive, for example, in the case that concentrated searching toward specific resources reduces diversity in collective behavior. First, we focus on adaptive property of misperception, and pro...

Many kinds of interactions among individuals construct collective animal behavior, but how to apply this multiplicity of interactions is often unclear when constructing models. We propose multiplicity of interaction in a simple model constructed from three factors: asynchronous updating, learning site patterns, and agent anticipation. We found that the first two contribute to an efficient searc...
