In the decommissioning of the nuclear power plant, especially, for decontamination by radioactive substances caused by 2011 Fukushima nuclear power plant accident has affected the reconstruction after the earthquake, the dose evaluation and validation of the decontamination effect is very important. In order to prepare a novel passive-type dosimeter system which can applied to radiation dose monitoring...
The rapidly increase of personal robotic platforms and their applications in Japan represents a great challenge for universities to introduce undergraduate students the basic knowledge required to develop intelligent automated mechanisms. For this purpose; in this paper, we are presenting our approach to introduce first year undergraduate students of the Department of Modern Mechanical Engineering...
Skilled workers decrease in these years. Then it is a problem that skilled techniques and know-how of specific work are not taken over to next generations. Therefore, a controller which is based on human-skill is needed to design. On the other hand, various neural networks (NNs) have been proposed. These technologies of the NNs enable us to deal with the nonlinear systems, and they play an important...
This paper proposes a new visualizing method for analyzing a pulse caused by a heart beat signal from a car seat. The pulse signal is measured by piezoelectric sensors in the seat, in order to analyze characteristic frequency of the pulse with wavelet transform. It is needed a method for visualization of these signals based on the wavelet transform although there are 18 channels with different delays...
We propose an input interface using Foot-Step which is gestures of foot for information appliances while jogging. When we use information appliances while jogging, an input by Foot-Step is briefer way than conventional physical interfaces because of the hands-free capability.We developed a prototype of a Foot-Step system which enables a user to operate a menu selection system which is widely used...
This paper proposes training equipment using a balloon actuator-sensor system (BASS) for persons unable to move their hands because of injury or disease. BASS is able to control the stiffness adaptively using an adaptive learning impedance controller. The pneumatic actuator has excellent compliance and flexibility, which is good for a human-mechanical system. However, it is also nonlinear, hence high...
Ion-sensitive field effect transistors (ISFETs) produced on hydrogen-terminated homoepitaxial intrinsic diamond films exhibit pronounced sensitivity to pH of aqueous electrolyte solutions. Gating of the transistor channels is realized by immersing the ISFET into pH buffer solution which is in contact with the platinum gate electrode. Conductivity through the ISFET channel is studied as a function...
