This paper suggests two advantages of the biarticular muscle which has been said to play an important role in human's motion control; one is stiffness direction stabilization of an end effector which results in stabilization of the posture, and the other is inertia matrix diagonalization in the dynamics of a robot manipulator. In order to analyze these characteristics, we adopt three-pair six-muscle...
To confirm the long-term reliability of Cu(In,Ga)Se 2 (CIGS) solar cells, we investigated the I-V and C-V characteristics during tests under irradiation or dark condition. Under irradiation, the test samples showed a little increase in efficiency (η) and open-circuit voltage (V oc ) which showed their electrical durability to light irradiation. But the diode factor (η) and series...
