We observed structure and form of adult anulus fibrous of lumbar intervertebral disc at fibrous layer level. Anulus fibrosus of lumbar interverbral disc was delaminated microsurgical technique. 8 testing points were taken in each layer and the angles between their fibers going and horizontal plane were measured. We got the results: Fiber going angle at each measurement point ceaselessly increased...
Cognitive radio has become an effective theory to solve the inefficiency of the spectrum usage, especially the energy detection in spectrum sensing technique. Recently several researches have focused on the performances of sensing using Gaussian approximation instead of real chi-square distribution based on central limit theory. In this paper, we specifically investigated the errors caused by approximation...
A disturbance estimator was designed and integrated into an existing proportional and integral controller DC motor speed control system to improve the speed regulation. The DC motor in the existing control system possessed a large amount of cogging torque, causing a periodic speed error. This cogging torque was treated as an equivalent input disturbance which then was estimated using a disturbance...
A number of decoding methods, varying from common linear Gaussian models to more complicated point process frameworks, have been developed to infer hand movement from neuronal firing activity in the motor cortex. Most of these methods focus on estimating subjectpsilas hand trajectory in a continuous movement. We recently proposed a template-based time identification decoding approach and showed that...
In this paper, a weighted joint prediction mode is proposed. It not only compares the motion prediction and disparity prediction, but also compares the motion prediction, disparity prediction and the weighted joint prediction. Then, the prediction mode which leads the least prediction distortion is chosen as inter prediction. Experimental results show that the proposed encoding scheme can solve the...
This paper is motivated by networked control systems deployed in a large-scale sensor network where data collection from all sensors is prohibitive. We model it as a class of discrete-time stochastic control systems for which the observations available to the controller are not fixed, but there are a number of options to choose from, and each choice has a cost associated with it. The observation costs...
