In this paper, absolute positioning instrument using trilateration ultrasonic sensor is mainly proposed to estimate absolute position errors combined with estimated position and orientation from differential odometry integrated with gyroscope to calculate absolute position of mobile robot. In the method, the indirect Kalman filter is mainly used to estimate absolute position errors and the esti...

I alone am responsible for the opinions as they are expressed in this paper. The members of the Board were placed under great obligations by the kindness of planters, administrators, and doctors in Malaya, Java, and Sumatra, and I feel especially indebted to Dr. Chas. Lane Sansom, c.m.g., p.m.o., Fed. M. S.; Hon. W. Gilmore Ellis, p.c.m.o., Straits Settlements, and to Den Hogg. Ed. Gestr., Herr...

In this review we summarized literatures about biomechanical researches in kayaking. Biomechanical methods provide data on a number of analytical techniques and kayak moving posture for coaches and athletes. 3-D kinematic analysis, on-water dynamic analysis and surface electromyography measurement are the most common methods through which we can assess and describe effects of paddling technique...
