Outline of research and education

Outline of the chair of Biophysical system engineering

The primary concern of the lectureship is to study wide theories and techniques for the future development in the field of the laboratory science, which will not always met by conventional approaches. A fusion of a number of research areas such as in system and control, computer science, electronics, mechanics and operation research is aimed at with an expanding in new directions and opening new horizons to solve the problems of this challenging field.

Background of Research

Our interest has been concentrated to regulatory mechanisms of biological systems, which are mostly represented by bilinear systems relating to Volterra functional series. Our work had been for about 15 years related to Volterra series and its applications to the synthesis of control systems. In parallel, had been studied modeling and analysis of biological systems such as a regulatory system of estrous cycle and real-time study of rat sleep stage and physiological stages.

Outline of Education

Undergraduate education

In order to meet the ever increasing demands of medicine, highly sophisticated technology is required. To ensure what can be achieved and maintained in such an environment, students are requested to study widely engineering sciences such as system and information theories inclusive of applications of electronics and computers. Required course subjects are "Computer for Laboratory Automation","Practice in Computer for Laboratory Automation","Medical Instruments","Medical Engineering" and "Practice in Medical Engineering".

Postgraduate course

Taking into account a significant need to achieve higher degrees of autonomous operations for laboratory science, appropriate subjects are provided such as "Measurement of living systems" and "Medical information science". Students are required to study principle and method of measurements including developments of new intelligent sensors and their information processing systems.

Recent Research

Since more than 10 years we have developed electronic safeguard systems for controlling aimless behavior in senile elderly patients and their network system using distribution line and telecommunication network. The recent works are realization of physiological eye movements by automatic selection of control laws using artificial neural network, stereoscopic display of the inside image of brain and development of force display system to realize reactive force feeling on stereoscopic cutting of stereoscopically viewed image. Above all, artificial control of human respiration has been studied for more than 10 years, in which various methods have been tried such as Volterra series, fuzzy control, model reference adaptive control, adaptive pole placement method. The last method is being prepared for clinical application. In parallel with control of respiration, we have developed a new type of 2-cylindrical respirator whose various operational modes are set by outside signal. Flow sensor to measure flow velocity and volume is very essential for our development of above new type of a respirator.

The following research projects are listed, which are relevant to system theory and its applications to the synthesis of biomedical measurement and control systems and to the analysis of biomedical regulatory systems:

Biomedical measurement and control systems. The real-time processing and analyzing system of long term physiological data has been developed for laboratory automation.
Welfare system for the care of senile elderly people. For the care of aimless behavior in senile elderly patients, electronic safeguard systems and their network using public telecommunication lines have been developed.
Bionics of eye movements for industrial application. Physiological eye movements are realized for their application to industrial robots by automatic selection of control laws using artificial neural network.
Virtual reality for anatomy- and surgery- simulation. The force display system is one of the main subjects of virtual reality in this laboratory. The system is for the realization of reactive force feeling on stereoscopic cutting of stereoscopically viewed image, which is applied to the education of anatomy and surgery.
Control theories and their application to physiological system. Artificial control of human respiration has been studied, in which various methods have been tried such as Volterra series method, Fuzzy control, Model reference adaptive control and Adaptive pole placement method. In parallel with a control of respiration, a new type of respirator has been developed, of which various operational modes can be set by outside signals.
