In this paper, a real-time implementation of second-order adaptive windowing technique for acceleration estimation is presented slider crank mechanism. It shown that there are some critical parameters which should be carefully set to proper values satisfactory estimation. technique, the size window automatically enlarged until position errors will not out error bands defined by user. order show...

Adverse weather conditions have been shown to have a substantial impact on traffic flow operations following substantial adaptation effects in driving behavior. In quantifying these effects psycho-spacing models may be used. In this contribution it was examined to what extend adverse weather conditions influence the position of action points in the relative speed-spacing plane in these models, ...

Skilled throwers achieve accuracy in overarm throwing by releasing the ball on the handpath with a timing precision as low as 1 ms. It is generally believed that this remarkable ability results from a precisely timed command from the brain that opens the fingers. Alternatively, precise timing of ball release could result from a backforce from the ball that pushes the fingers open. The objective...

Dysphagia, a swallowing disorder, is a problem encountered frequently in the rehabilitation of stroke and head injury patients. In normal individuals, safe passage of a food bolus into the esophagus is ensured by laryngeal elevation and closure of the airway. Inadequate laryngeal elevation can lead to aspiration, choking, and even death. The course of recovery in the current clinical practice i...

In this paper, we have developed an efficient method for real time computation of Center of Pressure (CoP) sway area using a fast search and sort based on a numerical approximation of the Green-Gauss method. In addition, we investigated the correlations among the velocity, acceleration, path length, sway area, and mean frequency of CoP signals during quiet standing in healthy children and in ch...

This study investigated relationships between 10 m sprint acceleration, step kinematics (step length and frequency, contact and flight time), and leg muscle performance (power, stiffness, strength). Twenty-eight field sport athletes completed 10 m sprints that were timed and filmed. Velocity and step kinematics were measured for the 0-5, 5-10, and 0-10 m intervals to assess acceleration. Leg po...

It has been demonstrated that the acceleration signal has potential to monitor heart function and adaptively optimize Cardiac Resynchronization Therapy (CRT) systems. In this paper, we propose a non-invasive method for computing myocardial acceleration from 3D echocardiographic sequences. Displacement of the myocardium was estimated using a two-step approach: (1) 3D automatic segmentation of th...

Linear colliders (LC) on the energy 0.5–1 TeV are considered as the next step in the particle physics. High acceleration gradients, small beam sizes, precision tolerances, beam collision effects are main problems for linear colliders. In this paper we discuss physics motivation, parameters and status of current LC projects, ee, γγ and γe modes of operation, physical limitations on the energy an...
