This paper considers a linear regression model with censored data where each error term follows a multivariate normal distribution. In this paper we consider the diffuse prior distribution for parameters of the linear regression model. With censored data we derive the full conditional densities for parameters of a multiple regression model in order to obtain the marginal posterior densities of the relevant parameters through the Gibbs Sampler, which was proposed by Geman and Geman(1984) and utilized by Gelfand and Smith(1990) with statistical viewpoint.

In this article, new microstrip slow-wave bandpass filters using open loop resonator loaded with inter-digital capacitive fingers is proposed. The filter features not only compact in size, but also exhibits spurious stop-band rejection. Filters of this type with elliptic function and Chebyshev response are demonstrated. There is good agreement between experimental and full-wave electromagnetic (EM) simulation results.

비구조화된 전문DB는 이용자가 필요로 하는 부분을 지정하여 다양하게 탐색한 수 없고, 또한 부적합 정보가 다량 탐색된다는 단점이 있다. 이러한 문제점을 해결하기 위해서 문헌의 구조화가 시도되고 있으나, 지금까지는 대부분 형태적 논리구조에 기반한 탐색기법이 연구되어 왔다. 따라서 본 논문에서는 문헌의 구조화에 형태적인 논리구조 뿐만 아니라 의미적인 논리구조도 반영될 수 있도록 단락을 객체단위로 한 의미구조 관계를 규명하고 이를 전문DB 구조에 적용하기 위한 타당성을 고찰하였다.

본 연구는 전문 D/B의 본문 필드를 텍스트 언어학적 상부구조로 분할하고 태그를 부여함으로써 이용자의 목적이나 상황에 따라서 필요한 부분만을 검색할 수 있는 전문탐색기법의 타당성을 고찰하였다. 한 문헌은 다수의 텍스트 단위로 구성되며, 이 텍스트는 의사소통이나 인지과정의 기본 단위로써 문헌 전체를 통괄하는 상부구조에 의해 연결된다. 상부구조는 텍스트의 생성과 이해에 중요한 매개체 역할을 하며, 정보요구의 상황이나 목적과 밀접하게 관련되어 있음을 밝히고 정보검색시스템의 주요 대상인 학술문헌의 상부구조를 고찰하였다.

This paper CMOS full adder design method based on carry-propagation-free addition trees and a circuit technique, so called multiple-valued current-mode (MVCM) circuits. The carry-paopagation-free addition method uses a redundant digit sets called redundant positive-digit number representations. The carry-propagation-free addition is by three steps, and the adder can be designed directly and efficiently from the algorithm using MVCM circuit. We demonstrate the effectiveness of the proposed method through simulation(SPICE).

A method fully utilizing multiscale line filter responses is presented to estimate the point spread function(PSF) of a CT scanner and diameters of small tubular structures based on the PSF. The estimation problem is formulated as a least square fitting of a sequence of multiscale responses obtained at each medical axis point to the precomputed multiscale response curve for the ideal line model. The method was validated through phantom experiments and demonstrated through phantom experiments and demonstrated to accurately measure small-diameter structures which are significantly overestimated by conventional methods based on the full width half maximum(FWHM) and zero-crossing edge detection.

Among the compression methods of moving picture information, a motion estimation method is used to remove time-repeating. The Block Matching Algorithm in motion estimation methods is the commonest one. In recent days, it is required the more advanced high quality in many image processing fields, for example HDTV, etc. Therefore, we have to accomplish not by means of Partial Search Algorithm, but by means of Full Search Algorithm in Block Matching Algorithm. In this paper, it is suggested a structure that reduce total calculation quantity and size, because the structure using Bit Plane select and use only 3bit of 8bit luminance signal.
