In the paper, aimed at the shortcoming of trust region method, we proposed a algorithm using negative curvature direction as its searching direction. The convergence of the algorithm was given. Furthermore, combing trust region method and curve-linear searching techniques, a trust region algorithm, using general curvelinear searching direction, was proposed. We proved its efficiency and feasibi...

the functional response is an important characteristic of predator–prey interactions that determinate which predator species or stage classes of predator is the most effective for pest control. host plant morphological characteristics are the effective factors on predator’s functional response. the objective of this study was to determine whether differences in trichome density of wheat cultiva...

the parasitoid trichogramma brassicae bezdenko is used for inundative releases in biological control programs against lepidopteran pests in agro-ecosystems. age-specific functional responses of t. brassicae to different egg densities (5, 10, 20, 30, 40, 60, and 80) of sterilized eggs of ephestia kuehniella at 23±1°c, 60±5% rh, and 16:8 h (l:d photoperiod ) were studied. e. kuehniella densities ...

To enable the geometrical freedom envisioned for wireless power transfer (WPT), fast dynamic adaptation to unpredictable changes in receiver position is needed. In this paper, we propose an adaptive impedance-searching system that achieves good impedance matching quickly. For fast and robust operation, the proposed method consists of three steps: system calibration, coarse search, and fine sear...

This paper presents recent extensions to Poliqarp, an open source tool for indexing and searching morphosyntactically annotated corpora, which turn it into a tool for indexing and searching certain kinds of treebanks, complementary to existing treebank search engines. In particular, the paper discusses the motivation for such a new tool, the extended query syntax of Poliqarp and implementation ...

Various efficient generalized sphere decoding (GSD) algorithms have been proposed to approach optimal ML performance for underdetermined linear systems, by transforming the original problem into the full-column-rank one so that standard SD can be fully applied. However, their design parameters are heuristically set based on observation or the possibility of an ill-conditioned transformed matrix...

In order to enhance inter-particle cooperation and information sharing capabilities, an improved particle swarm algorithm optimization model is proposed by introducing the centroid of particle swarm in the standard PSO model to improve global optimum efficiency and accuracy of algorithm, then parameter selection guidelines are derived in the convergence of new algorithm. The results of Benchmar...

In this paper, we proposed a new type of seed for Blast-like homology search tools called "half seed''. This new seed is better than the "consecutive seed'' used by the original Blast tools in both sensitivity and efficiency. When compared with the "gapped seed'', which is proposed together with a new Blast-like searching tool, PatternHunter, this new seed offers a much wider range of choices f...

Personal photo retrieval is different from many search tasks in that all the targets are either known to the user, or they are about something the owner has seen. For this reason, generating queries for searching personal photos will more likely rely on an individual’s memory. In a pilot study of Personal file re-finding, the results suggested a change of retrieval efficiency over time for diff...

This study investigates alternative approaches to locating bumble bee nests for scientific research. We present results from three trials designed to assess: 1. The comparative efficiency of two detection dogs; 2. The ability of a dog to locate nests when carrying out repeat searches of agricultural habitats through the season; 3. The efficiency of a dog compared with human volunteers at findin...
