The paper is focused on the estimate of the uncertainty of the results obtained by a hybrid experimental/numerical procedure for the evaluation of the electric field induced in a human body radiated by a LF magnetic field produced by unknown sources. The procedure is based on magnetic field measurements in a limited number of points around the field source and makes use of the Boundary Element. A...
The byproduct gas in steel industry is one of the most significant energy resources of an enterprise. Due to the large quantity of yield, fluctuation, and various categories of users encountered in a blast furnace gas (BFG) system, it is very difficult to accurately predict the amount of gas to be generated and forecast the users' consumption demand. In this paper, a two-stage online prediction method...
The objective of this study is to design a robot system to assist the rehabilitation of patients so that they can afterwards do various daily activities. It is difficult to determine the desirable posture of a 9-DOFs exoskeleton manipulator in such a system and each joint control design as well. In this paper, we resolve the difficulties by mapping the kinematics of a human arm to that of the manipulator...
Zero-Moment Point (ZMP) is the most popular concept that is applied to stabilize the gait motion of a biped robot. However, the computation of the ZMP position and the dynamic model is highly complex, and so requires a considerable time. Therefore, to eliminate complex computation, this work designs a new locomotion control system for humanoid robots, which yields walking gait characteristics that...
In this study human motor cortical activity was recorded with a customized micro-ECoG grid during individual finger movements. The quality of the recorded neural signals was characterized in the frequency domain from three different perspectives: (1) coherence between neural signals recorded from different electrodes, (2) modulation of neural signals by finger movement, and (3) accuracy of finger...
This paper presents a fuzzy logic model to decode the hand posture from electro-corticographic (ECoG) activity of the motor cortical areas. One subject was implanted with a micro-ECoG electrode array on the surface of the motor cortex. Neural signals were recorded from 14 electrodes on this array while subject participated in three reach and grasp sessions. In each session, subject reached and grasped...
