Outline of research activities1. About the ions constituting of the artificial breeding water, the influence of those components and concentration on the aquatic organisms is under study. Also, we investigate about the physiological effect caused by feeding a long time period and are developing “more suitable environment water”.
2. In the initial breeding of some types, so many aquatic organisms would die than in the mid-term breeding. This case would happen because of the unsuitable environment around the larvae and the low tolerance to the change. So we have been solving these problems and demonstrating the environment for the initial breeding of the larvae.
3. In the long term breeding of R.A.S., some materials derived from the feed to the breeding water will often accumulate. So we study the efficient methods of draining these materials out of the system.- Desired cooperation

Outline of research activitiesThe efficiency and performance of many industrial control systems depend on embedded servocontrollers. However, the presence of non-linear, time-varying unmeasurable disturbanses often lead to inability of the system to achieve low values of steady state error and may limit the closed loop bandwidth. Hence, the disturbance rejection is one of the most important and applicable design problem. I work in design and analysis of intelligent control systems including online identification of unknown system model parameters and rejection of unmeasurable disturbances. Another major research topic is development of intelligent UAV (drones) robots and their application in autonomous inspection of electrical energy transmission facilities, buildings etc..

Outline of research activitiesMy recent research activity is to find sufficient conditions for global asymptotic stability of equilibrium solutions of delayed partial differential equations with diffusion. An application is the SIR or SEIR epidemic model, which visualizes the results obtained in general theory using a computer (SDGs03). In addation, we have main study to search the sufficient condition which is equivalent to some kind of weakly asymptotically stable, in order to obtain the existence theorem and property of the family of almost periodic solutions to the functional difference equations with time delay. For this example, we construct a model of the erectile dysfunction by the radiational minimal explosion and by analyzing this model, and also we are studying the condition of coefficient on functional difference equations to adapt the real case of erectile dysfunction. Moreover, we verify from aspect of the sex medicine that this constructed model well explains a family of almost periodic system which appears the case of the erectile dysfunction by the radiation minimal explosion whether or not, by cooperating with a team of the department of urology in Kawasaki Medical University (SDGs03,SDGs15).

Outline of research activitiesAshworth scales have been used as a method to evaluate the muscle tonus of the patient having spasticity.This method however cannot evaluate it without the enforcer’s subjective judgment.Therefore we analyze the motion of leg by measuring pendulum motion (Pendulum Test) to evaluate the spasticity objectively.
The picture shows two one axis accelerometer were attached to a leg to measure leg motion.Because the angle output of the leg is only provided by the motion capture directly, 2 times differential calculus operation is necessary to obtain the angular acceleration output convenient to evaluate.In contrast, the angular acceleration output is provided directly with our method.- Desired cooperation
