Introduction SOSORT Consensus Conference (Milan 2005) developed about the main important features of a correct treatment based on physical exercises states that the main point is self correction. The SEAS school of treatment focuses on Active Self Correction (ASC) that is the series of movements of reallignemnt as a whole that the patients autonomously performs in order to reduce the scoliotic ...

6 grade students learned about horizontal projectile motion through Compare and Contrast (CC) instruction or Invention (INV) activities using identical contrasting cases generated by a Physics Education Technology (PhET) computer simulation. Results showed that the INV treatment led to superior learning outcomes over the CC condition. Worksheet analyses revealed that CC students mainly focused ...

introduction abnormal neural impulses in the nervous system may lead to various diseases and disabilities. high frequency alternating currents (hfac) has been used to block the propagation of such impulses and improve the symptoms or disabilities. the technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

Interactive computer simulations with complex representations and sophisticated graphics are a relatively new addition to the classroom, and research in this area is limited. We have conducted over 200 individual student interviews during which the students described what they were thinking as they interacted with simulations. These interviews were conducted as part of the research and design o...

For students using carefully designed computer simulations, we nd that the type of guidance provided to the student during interviews strongly in uences the amount of independent exploration and inquiry in which they engage. What would be considered relatively little guidance for typical educational activities appears to limit the bene ts of a complex simulated environment. In a study of studen...

The present study involves a novel computational technique, regarding simultaneous use of the pseudo particle method, Poisson integral method and a special-purpose computer originally designed for molecular dynamics simulations (MDGRAPE-3). In the present calculations, the dynamics of two colliding vortex rings have been studied using the vortex method. The present acceleration technique allows...

This paper deals with fuzzy cellular neural networks (FCNNs) with leakage delays and proportional delays. Applying the differential inequality strategy, fixed point theorem and almost periodic function principle, some sufficient criteria which ensure the existence and global attractivity of a unique almost periodic solution for fuzzy cellular neuralnetworks with leakage delays and p...

 The widespread use of the social media has recently created a lot of interest in research on human interactions, and how ideas propagate among individuals. We review the standard rumor model adopted from the literature. These models assume that people spreading the rumor (spreaders) keep spreading it, and those who hear the rumor (ignorant) can become a spreader with a certain probability. We ...

Identifying the projective group for patterns by developing the camera model, the projective Fourier transform and its inverse are obtained in analogy with the classical, that is, Euclidean Fourier analysis. Projectively adapted properties are demonstrated in a numerical test. Using the expression of the projective Fourier integral by a standard Fourier integral in the coordinates given by the ...
