We propose the system of charge and current densities realizing static and non-static electric solenoids. There is a non-trivial electric vector potential outside the electrical cylindrical or toroidal solenoids. It cannot be eliminated by the gauge transformation. The non-static solenoids emit waves of electromagnetic potentials propagating with the velocity of light. Conditions under which th...

This document describes how to use the 'static-static Elliptic Curve Diffie-Hellman key-agreement scheme (i.e., Elliptic Curve Diffie-Hellman where both participants use static Diffie-Hellman values) with the Cryptographic Message Syntax. In this form of key agreement, the Diffie-Hellman values of both the sender and receiver are long-term values contained in certificates. Status of This Memo T...

due to the high penetration of wind farms in the networks, they can have a significant role in the control of power systems. in this paper, wind farms (wfs) are used to improve the static security margins of the power system. generation rescheduling is one of the remedies to improve the static security margins of the power system. in this paper, the generation rescheduling is presented based on...

the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...

conclusions it seems that plantar changes have insignificant effect on static and dynamic indices evaluated by the biodex balance system. objectives the current study aimed to evaluate the relation between these structural characteristics and balance indices. patients and methods the study population was 100 male and female students from semnan university of medical sciences, semnan, iran. to e...

power stations produce a range of magnetic fields more than 20 mt which are harmful to those working or living around them. several investigators have reported an increased health risk due to exposure to electric and magnetic fields (emf) at 50 and 60 hz. several studies have been reported especially with increased tumor incidence, effects on reproduction and development, and neural and behavio...

stretching is an ancient method of treating soft tissue structures amongst the historical cultures. this method, in addition to other manual techniques such as, massage and manipulation has been taught in ancient medicine. nowadays, a wide range of studies have been performed to reveal the effects of this manual method on different muscle groups in patients, as well as healthy athlete subjects....
