— Effective robotic simulation depends on accurate modeling of physics and the environment as well as the robot, itself. This paper describes validation studies examining feature extraction, WaveLan radio performance, and human interaction for the USARSim robotic simulation. All four feature extraction algorithms showed strong correspondences between data(More)
—Attitude control refers to controlling the pitch and roll of a mobile robot. As environments become more complex and cues to a robot's pose become sparser, it becomes easy for a teleoperator using an egocentric (camera) display to lose situ-ational awareness. Reported difficulties with teleoperated robots frequently involve rollovers and sometimes even(More)
We provide a progress update on the spin wave nanofabric. The nanofabric comprises magneto-electric cells and spin wave buses serving for spin wave propagation. The magneto-electric cells are used as the input/output ports for information transfer between the charge and the spin domains, while information processing inside the nanofabric is via spin waves(More)
BACKGROUND The authors conducted a Phase II study to evaluate the activity of the combination of gemcitabine and vinorelbine in patients with advanced nonsmall cell lung carcinoma (NSCLC). METHODS Patients were eligible if they had Stage IIIB (malignant pleural effusion) or Stage IV NSCLC, no prior chemotherapy, and Cancer and Leukemia Group B performance(More)
