The loss minimum reconfiguration problem in the open loop radial distribution system is basically one of complex combinatorial optimization, since the normal open sectionalizing switches must be determined appropriately. The genetic algorithm was successfully applied to the loss minimum reconfiguration problem. In the proposed algorithm, strings consist of sectionalizing switch status or radial configurations, and the fitness function consists of the total system losses and penalty value of voltage drop and current capacity violations. The loss minimum reconfiguration problem is formulated as a mixed integer programming problem. The essential components of the genetic algorithm are briefly described. A detailed solution methodology by the use of genetic algorithm is outlined. Numerical examples demonstrate the validity and effectiveness of the proposed methodology 相似文献

This paper proposes deep and fundamental structures of communication among persons in a “coexistential” setting. The basic
framework for this formalization of communication structures is Leibnizian notions of space and time together with the notion
of the Existential Graph by C. S. Peirce and that of the Petri net, more precisely, the occurrence net. The fundamental structures
of coexistential communication are then formalized as co-creation of Leibnizian space and time in such a manner that they
are used to link the communicated messages, thus establishing the “coexistential atmosphere and field” (“Ba” in Japanese)
among the individuals. This framework is then applied to the analysis of theater play communication. Finally, the framework
of information edaphology is also introduced to discuss the growth processes of individuals and communities through coexistential
communication. 相似文献

A framework for “improvisational” social acts and communication is introduced by referring to the idea of “relationalism”
such as natural farming, permaculture and deep ecology. Based on this conception, the notion of Existential Graph by C. S.
Peirce is introduced. The notion of extended self in deep ecology is substantiated based on the Roy Adaptation Model in Nursing
Theory and Narrative approaches. By focusing on Leibnizian notions of space and time and by introducing Petri net, a spatio-temporal
model of improvisation is constructed. This model is expected to substantiate the interesting notion of “Ba” proposed by H.
Shimizu reflecting Japanese culture. 相似文献

Conventional humanoid robotic behaviors are directly programmed depending on the programmer's personal experience. With this method, the behaviors usually appear unnatural. It is believed that a humanoid robot can acquire new adaptive behaviors from a human, if the robot has the criteria underlying such behaviors. The aim of this paper is to establish a method of acquiring human behavioral criteria. The advantage of acquiring behavioral criteria is that the humanoid robots can then autonomously produce behaviors for similar tasks with the same behavioral criteria but without transforming data obtained from morphologically different humans every time for every task. In this paper, a manipulator robot learns a model behavior, and another robot is created to perform the model behavior instead of being performed by a person. The model robot is presented some behavioral criteria, but the learning manipulator robot does not know them and tries to infer them. In addition, because of the difference between human and robot bodies, the body sizes of the learning robot and the model robot are also made different. The method of obtaining behavioral criteria is realized by comparing the efficiencies with which the learning robot learns the model behaviors. Results from the simulation have demonstrated that the proposed method is effective for obtaining behavioral criteria. The proposed method, the details regarding the simulation, and the results are presented in this paper. 相似文献

In this paper, we report the case of an Inclusive Design workshop. Inclusive Design is a design method that includes elderly
and disabled people not only in interviews, but also in the upstream design process such as basic design and survey analysis.
In the workshop, participants designed scientific educational materials that visually impaired and sighted people can use
together. To work together regardless of visual disability, participants used the image-processing system and the stereo copying
machine to make images tactile. We think that collaborative work with elderly and disabled people in Inclusive Design can
teach participants different perspectives and help to correct their biased view of each other. In fact, participants of the
workshop noticed several facts that they were not aware of before. That is, the Inclusive Design workshop can improve social
awareness. 相似文献

We propose a novel concept toward interfaces that can provide visually impaired persons with the opportunity to recover the
freedom to conceptualize their environment without depending on conventional voice synthesizer systems. Fourteen subjects
participated in ten experiments to provide results that evaluated their performances to conceptualize spatial information
based on cues in “artificial-sounding” (AS) and “natural-sounding” (NS) tones. The source of AS tones was the digitized sound
used by the vOICe Learning Edition, and the source of NS tones was fan noise with analogs in everyday listening. Experimental
results revealed that the use of NS tones was essential for improving the conceptualization performance of subjects as the
eventual users of novel human–environment interfaces.
