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...

UNLABELLED BACKGROUND/STUDY CONTEXT: Typical measures for assessing the useful field (UFOV) of view involve many components of attention. The objective of the current experiment was to examine differences in visual search efficiency for older individuals with and without UFOV impairment. METHODS The authors used a computerized screening instrument to assess the useful field of view and to cha...

A robust archived differential evolution algorithm is put forward by means of embedding a flexibility processing operator and an efficiency processing operator based on original DE and ADE. A special constraint-handling mechanism based on dynamic penalty functions and fitness calculation of individuals is adopted in the proposed method to deal with various constraints effectively, which is furt...

We present an animation in Java for exact string matching algorithms 3]. This system provides a framework to animate in a very straightforward way any string matching algorithm which uses characters comparisons. Already 27 string matching algorithms have been animated with this system. It is a good tool to understand all these algorithms.

The number of copyright registrations for music documents is increasing each year. Computer-based systems may help to detect near-duplicate music documents and plagiarisms. The main part of the existing systems for the comparison of symbolic music are based on string matching algorithms and represent music as sequences of notes. Nevertheless, adaptation to the musical context raises specific pr...

The Range Next Value problem (Problem RNV) is a recent interesting variant of the range search problems, where the query is for the immediate next (or equal) value of a given number within a given interval of an array. Problem RNV was introduced and studied very recently by Crochemore et. al [Finding Patterns In Given Intervals, MFCS 2007]. In this paper, we present improved algorithms for Prob...

In this study an efficient and accurate algorithm is proposed for Content-Based Image Retrieval (CBIR). The CBIR is performed in two steps: features extraction in images and similarity measurement for searching of similar images in image database. For efficient and effective CBIR system the features extraction must be fast and the searching must be accurate. In the proposed algorithm, the effec...

The widespread use of recent Peer-to-peer (P2P) file sharing has been mainly influenced by the scalability of their architecture and high versatile search mechanisms. However, most of the P2P networks construct loosely coupled overlay on the top of the internet based on the physical network constraints without taking user preferences or relationship into account. It leads to high inefficiency i...
