As the existed eye tracking devices are so complex that the restrictions on the position are too many and people have to wear special equipment, this paper introduces a novel method against eye tracking: using the five near-infrared light as the source of corneal reflex. With the help of our method, people won’t need any equipment against eye tracking. Our method is able to adapt to the natural...

This paper presents the methodology of tuning two position servo drive systems with Permanent Magnet Synchronous Motors (PMSM): Field Oriented Control (FOC) based on current model of motor and FOC based on voltage model of motor. These two strategies are Vector Control (VC) methods and provide a solution for high performance drives but the choice one of these algorithms determines the type of i...

Object tracking is a process of segmenting a region of interest from a video scene and keeping track of its motion, position and occlusion. The tracking is performed by monitoring objects’ spatial and temporal changes during a video sequence, including its presence, position, size, shape, etc. Object tracking is used in several applications such as video surveillance, robot vision, traffic moni...

In the field of motion estimation for surveillance video, various techniques have been applied. One of the common approaches is Kalman filtering technique and it is interesting to explore the extension of this technique for the prediction and estimation of motion via the image sequences. In this paper, a moving object tracking in surveillance video using Kalman filter is proposed. The typical K...

The wake position is crucial feedback information for closed loop wind farm control. This paper presents a center tracking approach based on turbine rotor loads, which feasible to track the while impinging downstream turbine. equivalent characteristics are estimated blade root bending moments. Furthermore, wake-wind model developed describe relationship between averaged and position, in velocit...

In this note, a continuous, time-varying tracking controller is designed that globally exponentially forces the position/orientation tracking error of an underactuated surface vessel to a neighborhood about zero that can be made arbitrarily small [i.e., global uniformly ultimately boundedness (GUUB)]. The result is facilitated by fusing a filtered tracking error transformation with the dynamic ...

Socially differentiated tracking of health and health behaviours may contribute to health inequalities in adulthood. The modifying effect of socio-economic position on the tracking of overweight from mid-adolescence (age 15 years) into adulthood (age 27 years) was assessed in a randomly sampled Danish cohort (n = 561). The tracking was studied by prediction analyses conducted by logistic regres...
