Installation of Mechatronics Education Using the MindStorms for Dept. of Mechanical Engineering, O.N.C.T

The author constructed an installation course of mechatronics and conducted on the students of department of mechanical engineering, Oita national college of technology. The course is composed of six sessions and is aiming to grow up the mechanical engineers who can adapt quickly to changes in industrial society. Then, the education programs of computer technology and information processing are more emphasized in this course. Certainly the specific subjects involved with mechatronics are constructed as a part of curriculum in the older grades, however there is some difficulties to make students of department of mechanical engineering to have interests in electronics and/or information science. Viewed in this light, it is better to begin mechatronics education with undergoing experiments like this course since they were in early grade

CHANGES IN INTER-LIMB MUSCLE COORDINATION INDUCED BY MUSCLE FATIGUE DURING PEDALING

The purpose of this study was to investigate the changes in inter-limb muscle coordination brought about by muscle fatigue during pedaling. Four healthy male road cyclists pedaled for 15 min under a 150 W exercise load and a 90 rpm cadence. First, the surface electromyography (sEMG) of the muscles of both lower limbs was measured along with crank angle. Second, the slope of median frequency of a short-time Fourier transform was used to estimate muscle fatigue. Next, non-negative matrix factorization was applied to the time-frequency components of the sEMG to investigate the inter-limb muscle coordination. The result showed that asymmetrical inter-limb muscle coordination was seen in all subjects regardless of muscle fatigue. Failure to counteract muscle fatigue could be explained by the redistribution patterns of the asymmetrical inter-limb muscle coordination, which is considered a muscle fatigue compensation strategy

Use of the Structure of Blood Vessel for Detection of Brain Aneurysm and Route Search to Brain Aneurysm

Abstract: In this research, we constructed functions that are necessary for the operation simulation system which assists medical students to inhibit brain aneurysm from exploding. The system reported in this paper is “detection of blood vessels”, “detection of brain aneurysm ” and “route planning to brain aneurysm”. Not only the detection method but also the method to reduce the miss detection is realized for the detection of blood vessel. Finally, the future work will be shown including construction of head model consisting of artery, vein, brain and craniu
