With the launch of a feed-in tariff (FIT), together with a renewable portfolio standard (RPS) and a photovoltaic FIT, three renewable electricity support policies have temporarily coexisted in Japan since 2012. In the policy cost shift scheme, the amount of the purchased kWh from renewable electricity, with avoided costs subtracted, is added to electricity fee as a type of cost, called additional...
This paper proposes a new method of the interaction force control based on impedance control and B-spline interpolations for a human training system. The supporting interaction force to the human training is adjusted by the automatic load regulation. The automatic load regulation based on impedance control and B-spline function for training system in human stroke is developed. The robotic features...
The growth of the internet brings up new keywords for the information technology, such as cloud computing and big data. The increasing data in the information society has a potential to offer new insight into the real world. On the other hand, the increasing demand for rehabilitation of aged people has resulted in increased demand for physical therapy robots. Therefore, this paper proposes the construction...
This paper shows the experimental measurement results of the myoelectric signals of upper limb for the evaluation of the individual physical function. The evaluation is based on the functionally effective muscular strength (FEMS) theory. FEMS theory can express the relationship between each muscle strength and the force distribution of the arm end-effector. Then, the measurement experiments are conducted...
This paper reports high-performance position and force control of helical motion motors. This motor is an axial-gap surface permanent magnet (SPM) synchronous motor having helical stator and rotor. Thanks to this shape, this direct-drive motor can generate high thrust force without using any mechanical transmission system. The experimental results show that thrust force of 200N is achieved by the...
Japan has involved several social problems, e.g., large scale disasters and aging of infrastructures, and the robots working in a related special environment have been expected for the countermeasures. In order to accelerate the utilization of the robots, we need not only the development of technology but also the enforcement of comprehensive social system. In this aim, New Energy and Industrial Technology...
This paper reports a study on disaster response robots that would be built in and institutional problems that should be solved for evolution of promising unmanned construction system. This study has been conduction as part of the Council on Competitiveness-Nippon 2012 project [1]. First, this paper presents importance of promising unmanned construction system. Secondly, are presented technologies...
In the phases of mitigation, response and recovery of disaster, robots are needed for remote/automatic reconnaissance and task execution in inaccessible/dangerous area as agents of human. This paper presents proposed priority issues of disaster robotics for reducing risks, which were discussed at committees of NEDO (New Energy and Industrial Technology Development Organization) and COCN (Council on...
In March 11, 2011, worst disaster called Sendai Quake attacked the north east side of Japan. In the disaster area, Tsunami removed the all building, so, we need simple and easy medical equipment. As the portable device, Electric doctor bag has been invented. In the traditional and alternative medicine, a pulse diagnosis is one of the most important diagnostic methods. However, there was no paper in...
The eastern part of Japan experienced a magnitude 9.0 earthquake followed by a tsunami on the afternoon of March 11, 2011. A significant number of people were displaced from their homes and began living in temporary shelters. These shelters were located in schools, gymnasiums and 1 community centers, some of which were damaged and had inadequate facilities for the number of people they housed. I Subsequently,...
This paper reports basic methods of victim identification actually used in the Great East Japan Earthquake and Tsunami on March 11, 2011. In this disaster, it was proved that dental identification is very effective compared with other biometric identification methods such as fingerprint/palmprint identification and DNA-based identification. We designed and implemented a workflow of dental identification...
Automated detection of lesions in retinal fundus image can be aid in the detection of diabetic retinopathy. Exudates are the early sign of diabetic retinopathy so the proper detection of these lesions is an essential task in an automatic retinal screening. On the research work leading to automatic analysis of exudate detection, the knowledge of Optic Disk (OD) location is very useful. An efficient...
In many companies of the province of Tohoku (North-East Japan), stock prices were declining just after the East-Japan earthquake. However, on the other hand, some companies' stock prices rose in Tohoku. We have analyzed the reasons using text mining technologies on web data. In our studies, a combination of a stock price analysis and the text mining of the company can weave unexpected facts like a...
The remote sensing Synthetic using Aperture Radar can obtain the information of moving targets on the earth surface using MTI (Moving Target Indication) technique, which detects differentiation of the surface image data obtained in successive sessions taken with two antennas mounted on one satellite or two satellites flying in a close formation. In the latter case, the operation of the differentiation...
Displays are the key devices for reading data without errors at factories and offices efficiently. In addition, selection of displays is very important to keep the human eyes healthy if displays are contiguously operated for a long time of more than 100 min. Readability is the performance of display defined as the human-machine interface, strongly related to the physical capability of human eyes to...
Nowadays Java has been educated in many universities and professional schools as a reliable, portable, and practical programming language. To assist self-studies by students, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS has the two main functions of code writing problem and fill-in-the-blank problem to support studies at different levels. The former function...
Natural disasters results in large scale destruction of infrastructure including communication and buildings. With the communication infrastructure failure, it is very difficult to identify people related to us and confirm their safety. In such contexts reliable real-time information is critical. The paper discusses a method for personal identification during disaster situations by ID tagging. The...
