    A novel DC current transformer (CT) based on the Faraday Effect has developed for DC railway power system. The advantages of the developed optical fiber CT are simple and light structure, easiness to handle and robustness to the external magnetic field caused by the adjacent electric current. The basic characteristics of the optical fiber CT are confirmed and compared with those of the conventional Hall CT and saturable reactor CT. Through the fired test and DC short circuit test, it is shown that the optical fiber CT realizes enough response and enough resolution for the practical application. Furthermore, its strong robustness to the external magnetic field is experimentally confirmed.

  3. [해외논문]   方向サイズ可変フィルタを用いた下水道内面ひび割れ候補画素の検出  

    Hatada, Toshiyuki , Goto, Kunihiro , Saitoh, Fumihiko , Oosaka, Takayoshi , Numao, Shinji , Harimoto, Noriyuki

    초록

    This paper proposes a method to detect cracks in the inner side of a drain by using the edge detection techniques. Cracks can be recognized as lines with a thin width. Therefore a method for extracting edges is assumed to be useful to detect cracks. To detect a crack with an arbitrary global form, the variable-sized directional filter is applied. This filter can be set at every pixel with an optimal size and with an optimal direction. After the filter process, the threshold technique that determines a threshold to detect a crack by using its global feature is processed. The experimental results show that the proposed variable-sized directional filter and the threshold technique were effective to detect cracks in the images of inner side of drain.

  5. [해외논문]   Large-Scale Traffic Network Control Based on Convex Programming Coupled with B&B Strategy  

    Kato, Tatsuya (Nagoya University ) , Kim, YoungWoo (Toyota Technological Institute ) , Okuma, Shigeru (Nagoya University ) , Narikiyo, Tatsuo (Toyota Technological Institute)
    電氣學會論文誌. IEEJ Transactions on Electronics, Information and Systems. C : 電子·情報·システム v.126 no.6 ,pp. 752 - 760 , 2006 , 0385-4221 ,

    초록

    This paper presents a new framework for traffic flow control based on an integrated model description by means of a Hybrid Dynamical System (HDS). The geometrical information on the traffic network is characterized by a Hybrid Petri Net (HPN). Then, the algebraic behavior of traffic flow is transformed into a Mixed Logical Dynamical System (MLDS) form in order to introduce an optimization technique. These expressions involve both continuous evolution of traffic flow and event driven behavior of traffic light. HPN allows us to formulate the problem easily for complicated and large-scale traffic network due to its graphical understanding. MLDS enables us to optimize the control policy for traffic light by means of its algebraic manipulability and use of model predictive control framework. Since the behavior represented by HPN can be directly transformed into corresponding MLDS form, the seamless incorporation of two different modeling schemes provide a systematic design scenario for traffic flow control.

    In this paper, we show an approach to acquire a rule which is capable of achieving effective elevator services. The allocation of elevators to hall calls is taken as the decision variable and the Pitt approach of a Genetics-Based Machine Learning (GBML) method is designed according to the representation and the characteristics of the problem. We use a rule architecture in which a combination of some measures is directly encoded as a unit-rule and an elevator allocation procedure is represented as a rule set composed of some unit-rules. Five measures are developed based on the results of the preliminary experiment and it is shown that the rule as the weighted summation of the measures (called WS) is more effective than a conventional elevator allocation rule. In computational experiments, the up-peak, down-peak and two-way traffic patterns are considered and three rule sets are acquired by applying the GBML method. Based on the results, we can confirm that the GBML method can acquire some unit-rules appropriate for the targeting traffic patterns, and we can mention that, for some presumed traffic patterns, the possibility of constructing an effective rule set by combining some specific rule sets.

    초록

    In this paper, we propose an autonomous decentralized scheduling method with an optimization function of lotsizing and scheduling for multi-stage aluminum production line. The proposed method repeats the generation of schedule at each production process and data exchange among scheduling subsystems until a feasible schedule for the entire plant is derived. Two types of lotsizing and scheduling methods are compared for various size of example problems. The results demonstrate that the simultaneous optimization of lotsizing and scheduling must be considered when intermediate storage cost is embedded in the objective function.

    This paper proposes a robust independent component analysis (ICA) approach for noise reduction. Noise reduction is a difficult problem in ICA model. In general signal processing applications, there are more than one interference signal which may have unknown characteristics. In these situations, traditional linear ICA may lead to poor results. Hence, noise reduction is preferred to be performed with nonlinear adaptive filtering. In this paper, a radial basis function network (RBFN) is employed to transform the observed signals into output space in a nonlinear manner. The weights of RBFN are updated by utilizing a modified fixed-point algorithm. The proposed method has not only the capacity of recovering the mixed signals, but also reducing noise with unknown characteristics from observed signals. The simulation results and analysis show that the proposed algorithm is suitable for practical unsupervised noise reduction problem.
