To support legacy migration to service-oriented architecture (SOA), this paper presents a method that derives candidates of SOA services from procedural programs. In SOA, every service is supposed to be a process (procedure) with (1) open interface, (2) self-containedness, (3) coarse granularity for business. We identify such services from the source code and its data flow diagram (DFD), by analyzing...
Neural networks are able to learn more patterns with the incremental learning than with the correlative learning. The incremental learning is a method to compose an associative memory using a chaotic neural network. In the former work, it was found that the capacity of the network increases along with its size, with some threshold value and that it decreases over that size. The threshold value and...
We propose methods to control viewing zones of large screen consisted of full-color LED panel. Large parallax barriers have been developed for public 3-D display. By changing pixel arrangements, locations and number of perspectives can be reconstructed. Response of viewer's position caused by a shift of viewing was detected to evaluate the design of stereoscopic viewing zone. Furthermore, an array...
Er2SiO5 crystal shows strong and sharp Er-related PL emissions at room temperature. It is expected as a basic material of waveguide amplifiers in silicon photonics. Recently we have proposed Er2SiO5 crystal preparation by Pulsed Laser Deposition (PLD) method for device applications. In this paper we introduce PLD approach to modify crystalline structures of Er2SiO5 crystal and the related materials...
ErxY2-xSiO5 (x=0.1~2) crystalline thin films with the same structure of Er2SiO5 crystal are demonstrated. ErxY2-xSiO5 films with various x values were prepared by the sol-gel method. ErxY2-xSiO5 films show a highly-ordered crystalline structure still for x~0.1. With decreasing the Er content, the photoluminescence intensity was almost constant till x~0.5, and then increased strongly for x below 0...
Removing noise while preserving and enhancing edges is one of the most fundamental operations of image/video processing. However, removing noise and edge enhancement are conflicting requests, thus it is difficult to realize these two requests at the same time. Zhang and Allebach have proposed the adaptive bilateral filter (ABF) in order to realize the nose removing and edge enhancement at the same...
It is very important to develop 3D audio display systems compatible with future 3D visual displays in order to realize future 3D multimodal communications systems such as 3D television. In this paper, two 3D audio display systems using the radiated loudspeaker, that were developed by the authors, are described. In one system, the spherical radiated loudspeaker, which consists of 26 loudspeaker units...
A new design method called MORDE (multi-objective robust design exploration), which conducts both a multi-objective robust optimization and data mining for analyzing trade-offs, is proposed. For the robust optimization, probabilistic representation of design parameters is incorporated into a multi-objective genetic algorithm. The means and standard deviations of responses of evaluation functions to...
Bit-length (i.e., resolution of signal amplitude) of digital images is decided by the quantization. The bit-length expansion technique is necessity for the high-quality display such as the liquid crystal display (LCD) and the plasma display. Since, these displays have more the 10 bit resolution for each color component. However, in general, color image signals are defined by 8 bit resolution for each...
