  • This paper presents a new hybrid method for solving nonlinear complementarity problems with $P_0$-functions. It can be regarded as a combination of smoothing trust region method with ODE-based method and line search technique. A feature of the proposed method is that at each iteration, a linear system is only solved once to obtain a trial step, thus avoiding solving a trust region subproblem. Another is that when a trial step is not accepted, the method does not resolve the linear system but generates an iterative point whose step-length is defined by a line search. Under some conditions, the method is proven to be globally and superlinearly convergent. Preliminary numerical results indicate that the proposed method is promising.

  • Objectives : An atlas of tripple energizer affords to make us understand what the ancients thought it shaped. Methods : All pictures of it were picked out from traditional east Asian medical books where the atlas of every organ had been inserted. To be sure what it shaped, they were classified according to shape. Results : Shang Han Lun Tiao Bian(傷寒論條辨) has been one of the 4 books that shows it in the entire atlas drawing all organs in traditional Chinese, Korean and Japanese medical books. 14 books have a picture of it, while 18 books have an atlas of each organ except it. Since its multiple functions could not be expressed on a canvas at once, it had 6 different shapes, including the picture in Shang Han Lun Tiao Bian. Conclusions : Most of them were more representational or conceptualized than realistic, because ancient people had drawn it to inform the various functions, rather to show the actual feature. As anatomy went out into the east world, the more actually it was drawn, the further it was away from the own purpose.

  • IPTV (Internet Protocol Television) is an efficient system which serves various contents to subscribing consumers by using the IP over a broadband connection. The IPTV services can be multi-channel broadcasting service, VoD, T-Commerce, video conference, on-line game and so on. TV Anytime metadata provides various description tools for TV program contents by which TV program contents can serve more information. In this paper, we mention about the overview and feature of IPTV and TV Anytime metadata, propose the essential functions in the EPG program of IPTV and survey the description tools for the proposed functions in EPG. Finally, we show the authored metadata and the implementation of advanced EPG application.

  • Pattern classification is one of the most important topics for machine learning research fields. However incomplete data appear frequently in real world problems and also show low learning rate in classification models. There have been many researches for handling such incomplete data, but most of the researches are focusing on training stages. In this paper, we proposed two classification methods for incomplete data using triangular shaped fuzzy membership functions. In the proposed methods, missing data in incomplete feature vectors are inferred, learned and applied to the proposed classifier using triangular shaped fuzzy membership functions. In the experiment, we verified that the proposed methods show higher classification rate than a conventional method.

  • On the basis of comprehensive analysis and summarization of the image fusion algorithms provided by PCI Geomatica software, deficiencies in image fusion processing functions of this software are put forwarded in this paper. This limitation could be improved by further developing PCI Geomatica on the user’ side. Five effective algorithms could be added into PCI Geomatica. In this paper, the detailed description of how to customize and further develop PCI Geomatica by using Microsoft Visual C++ 6.0, PCI SDK Kit and GDB technique is also given. Through this way, the remote sensing imagery fusion functions of PCI Geomatica software can be extended.

  • In this paper we present a microprocessor-based interpolator using algebraic arithmetic method. The interpolator consists of 2910 "bit-slice" microprocessor chips and 0.5K ROMs of microprogram memory. The system design is an instruction-data-based architecture with 250ns cycle time. A significant feature of the interpolator is that it has flexibility, very fast interpolatioon speed of (max) 250K pulses/sec, and performs additional functions simultaneously. Throughout the paper detailed explanations are given as to how one can design the hardware and software of the interpolator efficently. In addi- tion to hardware and software design, experimental results are pressented.ressented.

  • In this paper, I propose the experimental models to classify the consonants in the Vowel-Consonant-Vowel (VCV) speech chain into four phonemic groups such as nasals, liquids, plosives and the others. To classify the fuzzy patterns like speech, it is necessary to analyze the distribution of acoustic feature of many training data. The classification rules are maximum 4 th order polynomial functions obtained by regression analysis, contributing collectively the result. The final result shows about 87% success rates with the data spoken by one man.

  • Classification is an important research field in pattern recognition with high-dimensional predictors. The support vector machine(SVM) is a penalized feature selector and classifier. It is based on the hinge loss function, the non-convex penalty function, and the smoothly clipped absolute deviation(SCAD) suggested by Fan and Li (2001). We developed the algorithm for the multiclass SVM with the SCAD penalty function using the local quadratic approximation. For multiclass problems we compared the performance of the SVM with the $L_1$, $L_2$ penalty functions and the developed method.

  • We present a high resolution spectrum of PU Vul observed at Bohyunsan Optical Astronomy Observatory (BOAO) on April 9, 2004. Permitted emission and nebular lines of PU Vul had been significantly changed compared to all spectra observed since its eruption in 1979. Therefore all new lines should be re-identified and were done so. We do-convoluted a $H{\beta}$ line into several emission components with Gaussian functions. Then we carefully discussed the geometrical feature of PU Vul in April 2004.

  • Current web-server deals a multimedia data as well as text data. But dealing a multimedia data is high burden to web-server. So it can degrade web-server response. We introduce H/W feature CDA (Contents Delivery Accelerator). Main function of this H/W is transferring data between SCSI disk and NIC by direct path, and TCP offloading. These 2 functions can accelerate web-server performance. In this paper we will explain problem of current web-server and suggest our new architecture and say various implementation issues.
