Many statisticians have been using object-oriented languages such as S-PLUS, R, and MATLAB to make programs for new data analysis methods. S-PLUS and R are slower in computation as well as in processing large data sets than MATLAB. Recently MATLAB is often used for developing statistical analysis programs owing to its fast computing ability and abundant mathematical algorithm modules. Sometimes it is hard for non-statistician to understand MATLAB programs which are developed by statisticians. Therefore Graphical User Interface(GUI) is needed to facilitate the usage of MATLAB codes. In this paper, we introduce how to develop a GUI for MATLAB codes which is executable on Windows with examples.

A geortor type pump is widely used in lubrication and actuator systems. Especially the pump is an essential machine element of an automotive engine to feed lubrication oil and power source of automatic transmission. A gerotor is a planar mechanism consist of a pair of rotor and circular tooth of stator assembly which forms a closed space. However, related industries do not have necessary technology to design and optimize the pump and paid royalties of gerotor profile on an advanced company. Also, gerotor profiles with setting design parameter have not been sufficiently analyzed from a theoretical view. Therefore, it is very difficult for designer to decide the specifications of the gerotor profiles, and calculation and fluctuation of flow rate is not yet confirmed. In this study, theoretical analyses and optimal design of the gerotor profiles have been performed numerical method by mathematical base. An automated design system of the tooth profile has been developed through MATLAB GUI Program considering various design parameters.

This paper introduces a MATLAB graphical user interface (GUI) based software for performance analysis of navigation message and wide area differential correction of regional navigation satellite system (RNSS). This software was developed to analyze satellite orbit/clock-related performance of navigation message and wide area differential correction simulating RNSS for regions near Korea based on different distributions of monitor and reference stations. As a result of software operation, navigation message and wide area differential correction are given as output in MATLAB file format. From the analysis of output, it was confirmed that valid navigation message and wide area differential correction could be generated from the results about statistical feature of orbit and clock prediction errors, cm-level fitting errors for navigation message parameters, and 81.9% enhancement in range error for wide area differential correction.

In this paper, multi-GNSS network RTK MAC correction generation software developed based on MATLAB GUI is introduced. The software was developed as a post-processing software based on simulation data to evaluate the feasibility of an algorithm for generating correction for multi-GNSS including GPS, GLONASS, and Galileo. As a result of software operation, network RTK correction for each system of multi-GNSS is output in MATLAB file format. In this paper, to evaluate the performance of the developed software, the residual error was analyzed after applying the correction generated through the software to the user. As a result of the analysis, it was confirmed that effective network RTK correction could be generated by confirming that the residual errors of users were maintained at 10 cm or less.

Arcing fault on overhead lines can be detected by amplitude of the arc voltage using numerical algorithm. In the case of transient fault, the arc voltage has any high value. In the case of permanent fault, the arc voltage is near zero. Thus, fault distance estimation should be performed by digital distance relay algorithm[3]. The purpose of this study is to build a structure for modeling of arcing fault detection and fault distance estimation algorithm using Matlab programming. Additionally, this algorithm has been designed in Graphical User Interface(GHI). So, this method using GUI interface of Matlab can reduce the number of simulation steps in modeling the distance relay.

본 연구는 철도 선로변에 설치되는 LDTS(Local Data Transmission System)와 EIS(Electronic Interlocking System) 사이의 인터페이스를 위한 정보전송 프로토콜에 대한 성능검증 시뮬레이션을 위한 것으로, LDTS와 EIS사이의 링크사양, 전송 메시지 정보 및 형식, 장치간 전송 프로토콜 기준 등을 분석하여 파라미터들을 추출한 후, 이들을 ARQ, FEC, HARQ 방식들에 적용하여 처리율(Throughput) 및 여러 설계변수들에 대한 시뮬레이션 결과를 비교하였다. 시뮬레이션 프로그램은 Matlab과 Matlab GUI 툴을 이용하여 작성하여 사용자가 손쉽게 시뮬레이션 파라미터들을 조정할 수 있도록 하였고, Matlab 프로그램 완성후에는 이를 Stand-alone C++ 프로그램으로 코드변환하여 Matlab이 설치되지 않은 컴퓨터에서도 프로그램 사용이 가능하도록 하였다.

Development of the reliability-based design program in the GUI environment is inadequate for engineers familiar with the deterministic design to deal with the international design criterion based on the probabilistic design. In this study, the design program based on the GUI environment is developed in order to more efficiently input the design factor and more easily carry out the design works. The GUI environment is the GUIDE (Graphic User Interface Development Environment) tool supported by the latest MATALB version 7.1. In order to test the model reliability, the probabilities of failure (POF) on the breakwater armor block (AB) and gravity quay-wall (QW) in the sliding mode are computed using the model in the Level II and Level III. The POF are 55.4~55.7% for breakwater AB and 0.0006~0.0007% for gravity QW. A non-GUI environment program results of the POF are 55.6% for breakwater AB and 0.0018% for gravity QW. In comparison, the POF difference is negligible for breakwater AB because the exact input design parameters are available, whereas the large POF difference, but within the same order, for gravity QW can be explained by the difference of the input design factors because of the poor input data information.
