  • 무선을 이용한 위치 추적방법은 최근에 많은 관심을 받고 있다. 이 방법들은 적용지역환경 및 대상에 따라 적절한 방법을 선정하여 사용하는 것이 중요할 뿐만 아니라 신뢰성을 갖는 것 또한 매우 중요하다. 본 논문에서는 일정한 노선으로 움직이는 열차라는 이동체를 대상으로 하여 적용 가능한 알고리즘에 대하여 검토하였으며, 이는 1차원에서 물체의 위치를 추적하는 방법으로써, 열차와 같은 일정한 노선 위를 이동하는 물체의 위상을 추적하여 이동체의 위치를 결정하는 알고리즘 구현을 위한 방법과 조건을 제시하였다.

  • 본 논문은 기존의 수동적 위치 추적 응용을 사용자가 시스템과 상호작용이 가능하도록 확장함으로 계속적으로 이 동하는 센서노드에게 사용자가 원하는 명령을 전달할 때 메시지의 양이 많아지는 문제점을 해결하기 위한 기법을 제시한다. 이 기법은 상황에 따라 전체 센서 필드에 데이터를 전파하는 full-scale flooding 과 지역적으로 데이터를 전파하는 constrained flooding을 상황에 따라서 선택 사용하는 방식으로 서로의 약점을 보완함으로 최대의 효과를 얻는다. 시뮬레이션을 바탕으로 full-scale flooding만을 사용했을 때와 비교했을 때 이동 노드의 수가 늘어 나는 과정에서 $10\%-90\%$까지 메시지의 양을 줄일 수 있었고, 최악의 상황에서도 full-scale flooding보다 그 결과가 나쁘지 않다.

  • In order to improve the voltage profile of the system we introduce the reactive power devices. However, it is difficult to know which bus will be the most effective bus when we inject the reactive power supplier in it. This paper systematically determines indices of the system in order to locate reactive power devices in a power system. To prove the validity and effectiveness of the system we apply the proposed method to the 9 bus system.

  • The primary clue for locating protein-coding regions is the open reading frame and the determination of ORFs (Open Reading Frames) is the first step toward the gene prediction, especially for prokaryotes. In this respect, we have developed a web-based ORF search tool called ORF Miner. The ORF Miner is a graphical analysis utility which determines all possible open reading frames of a selectable minimum size in an input sequence. This tool identifies all open reading frames using alternative genetic codes as well as the standard one and reports a list of ORFs with corresponding deduced amino acid sequences. The ORF Miner can be employed for sequence annotation and give a crucial clue to determination of actual protein-coding regions.

  • Locating text data in images automatically has been a challenging task. In this approach, we build a three stage system for text detection purpose. This system utilizes tensor voting and Completed Local Binary Pattern (CLBP) to classify text and non-text regions. While tensor voting generates the text line information, which is very useful for localizing candidate text regions, the Nearest Neighbor classifier trained on discriminative features obtained by the CLBP-based operator is used to refine the results. The whole algorithm is implemented in MATLAB and applied to all images of ICDAR 2011 Robust Reading Competition data set. Experiments show the promising performance of this method.

  • We develop a wireless, contact free power transfer mechanism that is safer than the direct metallic contact and robust to imperfect alignment on landing at the base station. A magnetic field is created using inductors on both the transmitting and receiving sides. We use the inductive wireless recharging to increase autonomy and decrease the sensor interference by reducing the inductor loop size. By locating four independent small receiver loops and corresponding four circuits around the quadrotor UAV, we can increase safety from circuit malfunctions in comparison to the use of just one loop. On the base station, four folding robotic bars are used to realign the receiver loops over the transmitter loops. After adequate recharging as measured by battery voltages or power consumption at the bae station, the UAV sends a signal to the base station to open the robotic bars and takes off once freed from the robotic bars.

  • This paper presents the design of an algorithm to detect, identify, and locate faults in radial distribution feeders of Provincial Electricity Authority (PEA). The algorithm consists of three major steps. First, the adaptive algorithm is applied to track/estimate the system electrical parameter, i.e. current phasor, voltage phasor, and impedance. Next process, the impedance rule base is used to detect and identify the type of fault. Finally, the current compensation technique and a geographic information system (GIS) are applied to evaluate a possible fault location. The paper also shows the results from field tests of the automate fault location and illustrates the effectiveness of the proposed fault location scheme.

  • The problem treated is that of locating distribution centers(depot) in a network, so as to minimize the total cost which is the sum of transportation cost, (from factory to centers and from centers to demand points), construction cost, inventory cost and traffic increasing cost. This problem is mathematically an integer program and a non-linear model. This study avoids various inefficient aspects, which many studies have shown, by introducing a matrix notation, node and link function. An algorithm, for determining the optimal location of distribution center which has zone in which demand points are located at some node of a network, is presented. Finally this paper describes a numerical example and discusses its results.
