PURPOSE To assess the feasibility and therapeutic benefits of a combination of external beam radiotherapy (EBRT) and high-dose-rate intraluminal brachytherapy (ILBT) for treating patients with inoperable carcinoma of the extrahepatic bile ducts. METHODS AND MATERIALS Of 31 patients who received RT at the Yonsei Cancer Center, Yonsei University College of(More)
The unified approach algorithm to control a mobile robot is useful in simplifying path planning and inverse kinematics by considering a mobile platform as hypothetical joints. Applying the damped least square method by using the Jacobian prevents the divergence of the joint angle. However, it is possible to violate the nonholonomic constraint on mobility by(More)
In this paper, a BLE (Bluetooth Low Energy) based new sensor fusion algorithm is proposed. We can estimate distance by using the signal strength from the BLE beacons. Other sensors support the estimation process which uses the proposed “constrained extended Kalman Filter”. BLE is more efficient than the existing wireless communication, and is(More)
