Since the reforming and opening up of China, domestic and foreign scholars have made deep researches on the total factor productivity of China, but the different estimation results led to much controversy. Herein, the new method is used to estimate the two key indexes of capital and labor input in the paper. Based on that, by extended Solow residual value Method to undertake an empirical study on...
Logic obfuscation can protect designs from reverse engineering and IP piracy. In this paper, a new attack strategy based on applying brute force iteratively to each logic cone is described and shown to significantly reduce the number of brute force key combinations that need to be tried by an attacker. It is shown that inserting key gates based on MUXes is an effective approach to increase security...
In this paper we present a method to stimulate multiple muscles in a human arm to perform interaction tasks, using an implanted Functional Electrical Stimulation (FES) neuroprosthesis. The unstable effect arising from interaction tasks is considered, and the arm stability is directly treated as one of the control objectives in the controller design. By exploiting the kinematic and muscular redundancy...
We present a method for controlling a neuroprosthesis for a paralyzed human arm using functional electrical stimulation (FES) and characterize the errors of the controller. The subject has surgically implanted electrodes for stimulating muscles in her shoulder and arm. Using input/output data, a model mapping muscle stimulations to isometric endpoint forces measured at the subject's hand was identified...
We present a method for controlling a neuroprosthesis for a paralyzed human arm using functional electrical stimulation (FES). The subject has surgically implanted electrodes for stimulating muscles in her shoulder and arm. Using input/output data, a model is identified that describes the mapping from muscle stimulations to the endpoint force measured at the subject's hand. To compute the muscle stimulations...
It is known that for an external push a humanoid robot can take three strategies, i.e. ankle strategy, hip strategy and step strategy, to recover balance. For the limited joint torque, the response strategy depends on the external push applied. This paper proposes a criterion for balance recovery based on initial phase plane by using inverted pendulum mode including angular moment. The step length...
Humanoid robots are widely discussed in recent years. The motion planning and control of humanoid robots can be discussed based on mobility of platforms and manipulations of arms. In this paper, we propose a robotic arm which manipulation is analog to the motion of humanpsilas upper extremities. The proposed robotic arm is designed as a seven degree-of-freedom configuration. To increase the interactivity...
