In manual order picking systems, order pickers walk or ride through a warehouse in order to collect items requested by customers. The performance of such a system is significantly dependent on its layout which determines the lengths of the order pickers’ tours and the corresponding picking times. Whereas for classic warehouse layouts all picking aisles are arranged in parallel to each other, in...

User-adaptive tour planning systems are tourist information systems that can make tour plans customized for individual users. Several systems have been already proposed, but such usability issues as frustrating preference/personality registration process and lack of sense of participation still remain. In this paper, we review these usability issues and discuss the following challenges for more...

A Response surface design of experiment has been performed based on the Muschelknautz method of modeling (MM) for 64 test cases using Box-Behnken design to study the effect of seven geometrical cyclone dimensions on the pressure drop and cut-off diameter. It is found that the most significant geometrical parameters are, the vortex finder diameter, the inlet section width and height, and the cyc...

SUMMARY To facilitate the designing process for vector-based siRNA and siRNA cassette, a tool set has been developed consisting of a siRNA target finder, a siRNA construct builder and a siRNA sequence scrambler. The siRNA target finder is used to identify candidate siRNA target sites. The program automates homology filtering, minimizes non-specific cross-reaction, filters target sites based on ...

This article describes a Hopfield-Tank model of the Euclidean traveling salesman problem (using Aiyer’s subspace approach) that incorporates a “fuzzy” interpretation of the rows of the activation array. This fuzzy approach is used to explain the network’s behavior. The fuzzy interpretation consists of computing the center of mass of the positive activations in each row. This produces real numbe...

Recommending and planning tour itineraries are challenging and time-consuming for tourists, hence they may seek tour operators for help. Traditionally tour operators have offered standard tour packages of popular locations, but these packages may not cater to tourist’s interests. In addition, tourists may want to travel in a group, e.g., extended family, and want an operator to help them. We in...

We present a new symmetric traveling salesman problem tour construction heuristic. Two sequential matchings yield a set of cycles over the given point set; these are then stitched to form a tour. Our method outperforms all previous tour construction methods, but is dominated by several tour improvement heuristics. c © 2004 Elsevier B.V. All rights reserved.

It is often difficult for individual tourists to make a sightseeing tour plan because they do not have prior knowledge about the destination. Although several systems have been developed for assisting the user’s tour planning, these systems lack interactivity, while demanding a lot of data input from the user. In this paper, we introduce a new computer-aided tour planning system, called CT-Plan...

作物の系譜情報は育種を行う上で必要不可欠であり，特に交配親の選定において極めて重要である．しかし，系譜情報の分析基盤や可視化ツールは少なく，育種家は範囲が限定された系譜図を使用せざるを得ない．本研究では，育種や作物データの解析に系譜情報を広く活用するため，系譜情報グラフデータベース「Pedigree Finder」（https://pedigree.db.naro.go.jp/）を構築した．系譜情報を整備するために語彙やデータフォーマットの統一を行うとともに，品種・系統の標準化されたIDを利用することにより，関連するゲノム情報および形質情報との紐づけを可能にした．系譜情報の整備にはデータモデルとしてリソース・ディスクリプション・フレームワーク（Resource Description Framework, RDF）を採用し，共通性と永続性を高めた上で，グラフデータベースを構築した．グ...
