A new type of communication between concurrent processes called ‘subjects’ and a synchronization mechanism are presented. Since the communication is carried out only based on reading the internal states of a subject, it is available at any time even in the case of a failure of some subjects.
Color plane separation is very useful in processing color document images. Many reported methods take it as a multi-class classification problem and work not well in overlapped color regions. This paper proposed a simple but effective linear projection based method for separating overlapped color planes. The separation task is taken as a probability problem, i.e., in the output plane, target color...
Quantum-dot (QD) semiconductor optical amplifiers (SOAs) offer large differential gain, good temperature stability, and low chirp due to the discrete energy states of the electrons and holes under three-dimensional quantum confinement by the QDs. And recent reports of their high saturation power, ultra-broad bandwidth, and unique nonlinear properties [1–4] have brought increasingly more attention...
We have developed the tool which is specialized to the target that a user is able to construct a word network while evaluating what word to set as a node. A co-occurrence network of words is a complex network with huge number of nodes and links and is not capable for man to interpret as it is. Therefore, we have designed its interface that displays a network as network confines gradually expand in...
We have utilized neural networks in different applications of bioinformatics such as discrimination of beta-barrel membrane proteins, mesophilic and thermophilic proteins, different folding types of globular proteins, different classes of transporter proteins and predicting the secondary structures of beta-barrel membrane proteins. In these methods, we have used the information about amino acid composition,...
Methods to rectify distortion of digital camera document images of curved papers have become important for camera-based image recognition. In this paper we propose a novel distortion rectification method based on "shape from parallel geodesies." This method considers the following features: parallel lines corresponding to character strings or ruled lines of tables on extended surface become...
We compared positioning accuracy of helium filled drives with that of standard air drives. We report the spectrums of PES and calculated mechanical disturbance. The results revealed that almost all disturbances in higher rpm drives are flow induced vibrations and that disturbances in helium drives are dramatically smaller. The experimental positioning error of helium drives is less than half that...
It is still unclear as to how cardiorespiratory fitness and visceral fat accumulation contribute to coronary heart disease (CHD) risk factors in patients with diabetes mellitus. The purpose of the present study was to investigate whether cardiorespiratory fitness contributes to such risk factors independently of visceral fat accumulation. Two hundred Japanese patients (137 men and 63 women, aged 22...
Purpose: As the second half of a software system for 3D structure prediction of membrane proteins, we have developed a method to determine the positioning, the rotation and the tilting of transmembrane helices, assuming that the polar interactions are essential for the 3D structure formation.Methods: The first stage of the 3D-structure prediction is the search of an energy ground minimum, assuming...
A novel sputter-deposited Al-Si-Pd alloy has been investigated for use for VLSI interconnection in place of Al-Si-Cu-alloy. Workability of the Al-Si-Pd alloy in submicron patterning has proved to be much better than that of Al-Si-Cu alloy, and both electromigration resistance and stress-induced migration resistance are higher than those of Al-Si-Cu alloy. Long-term reliability tests of a resin-molded...
