Vicon system is implemented in almost every motion analysis systems. It has many applications like robotics, gaming, virtual reality and animated movies. The motion and orientation plays an important role in the above mentioned applications. In this paper we propose a method to estimate arm joint angles from surface Electromyography (s-EMG) signals using Artificial Neural Network (ANN). The neu...

We applied information-theoretic methods to multi-electrode array recordings in the primary visual cortex of cats to quantify the cooperation and temporal structure that arise in the responses of neural populations to drifting sinusoid gratings. The temporal structure and joint firing in these responses contributed information useful for discriminating small (<10o) orientation differences. The ...

Recently, inertial sensors have been widely used in the measurement of 3D orientations because their small size and relative low cost. One useful applications area Neurorehabilitation is to assess upper limb motion for patients who are under neurorehabilitation. In this paper, computation orientation discussed utilising outputs from accelerometers, gyroscopes magnetometers. Different representa...

The neural control of hand movement involves coordination of the sensory, motor, and memory systems. Recent studies have documented the motor coordinates for hand shape, but less is known about the corresponding patterns of somatosensory activity. To initiate this line of investigation, the present study characterized the sense of hand shape by evaluating the influence of differences in the amo...

OBJECTIVE This research investigated factors associated with sexual orientation disparities in chronic pain frequency among youth. METHOD Data were analyzed from 4534 female and 3785 male youth from Waves I-IV (1995-2009) of the U.S. National Longitudinal Study of Adolescent to Adult Health. Gender-stratified weighted logistic regression models controlled for sociodemographic characteristics ...

There is no clear link between the broad tuning of single neurons and the fine behavioral capabilities of orientation discrimination. We recorded from populations of cells in the cat visual cortex (area 17) to examine whether the joint activity of cells can support finer discrimination than found in individual responses. Analysis of joint firing yields a substantial advantage (i.e., cooperation...

The ball-and-socket joint model is used to represent articulations with three rotational degrees of freedom (DOF), such as the human shoulder and the hip. The goal of this paper is to discuss two related problems: the parametrization and the deÞnition of realistic joint boundaries for ball-andsocket joints. Doing this accurately is difÞcult, yet important for motion generators (such as inverse ...

In this paper, we study the estimation problems for the Burr type III distribution based on a complete sample. The maximum likelihood method is used to derive the point estimators of the parameter. An exact confidence interval and an exact joint confidence region for the parameters are constructed. Two numerical examples with real data set and simulated data, are presented to illustrate the met...

Welding is one of the most successful applications for industrial robots, which encourages intensive research and development in the area of the CAD-based and off-line programming (Pires et al., 2003, Yagi, 2004). At present, relevant software tools allow to optimise the process parameters, which directly influence the product quality and the system working cycle. Besides, they enable users to ...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...
