Monte Carlo simulation is an essential tool in emission tomography that can assist in the design of new medical imaging devices, the optimization of acquisition protocols and the development or assessment of image reconstruction algorithms and correction techniques. GATE, the Geant4 Application for Tomographic Emission, encapsulates the Geant4 libraries to(More)
Influx of Ca(2+) through store-operated Ca(2+) channels (SOCs) is a central component of receptor-evoked Ca(2+) signals. Orai channels are SOCs that are gated by STIM1, a Ca(2+) sensor located in the ER but how it gates and regulates the Orai channels is unknown. Here, we report the molecular basis for gating of Orais by STIM1. All Orai channels are fully(More)
— The disturbance observer (DOB) has been widely utilized for high precision and high speed motion control applications. In this paper, we suggest the robustness measure of DOB, as a criterion to design the robust DOB systems. Also, we suggest its design guidelines especially for second-order systems. Experimental results for an optical disk drive system(More)
Giant swing via forward upward circling of the acrobat-robot, " Proc.lization of a class of underactuated mechanical systems via interconnection and damping assignment, " IEEE Trans. Abstract—This paper proposes the walking pattern generation method, the kinematic resolution method of center of mass (CoM) Jacobian with embedded motions, and the design(More)
— This paper proposes a method to accommodate multiple tasks for redundancy utilization, which is based on a specific weighted pseudo-inverse. The proposed method also has task priority imposition property as those conventional task priority based method. In order to deal with general situations of task specification, the so-called semi-definitely weighted(More)
— This paper proposes the walking pattern generation method, the kinematic resolution method of CoM(center of mass) Jacobian with an embedded motion, and the walking controller design method for humanoid robots. First, the walking pattern is generated using the simplified model for bipedal robot. Second, the kinematic resolution of CoM Jacobian with(More)
— In this paper, we present a simple method for visual localization of indoor mobile robots based on a natural landmark model. Only two natural lines and an intersection point are used for localization to take the advantage of fast detection. T o track the landmark model, Lucas-Kanade optical flow algorithm is applied by using gradient descent. Then, by(More)
