Crossing of bunches at an angle in a storage ring is studied. A case when a particle trajectory intersects the opposing bunch off-center and at an angle to the main axis of the bunch charge distribution is considered. Formulae for a kick experienced by a particle are derived for crossing in both horizontal and vertical planes. This kick is a function of the off-center distance in the longitudin...

slow sand filters are as a proper technology for pre-treatment of raw water, with a fine and medium trubidity in small communities in developing countries. thus, with a minimum operation cost and minimum need for expest bodies have the maximum efficiency. the purpose of this research is carried out to evaluate the efficiency of two processes of horizontal flow roughing filter and vertical flow ...

Tel./fax: +4 ess: info@norrisassociat Summary The purpose of this study was to determine if an association exists between hamstring muscle length and the angle of pelvic tilt during forward bending in a student sporting population. A bubble goniometer was used to determine angle of pelvic tilt, and the active knee extension (AKE) test used to a...

Quantifying spatial and temporal variations in optimal tilt angle of a solar collector relative to a horizontal position assists in maximizing its performance for energy collection depending on changes in time and space. In this study, optimal tilt angles were quantified for solar collectors based on the monthly global and diffuse solar radiation on a horizontal surface across Turkey. The datas...

To explore the effect of posture on muscle performance, we tested the effects of body tilt angle on the strength, endurance, and fatigue of, and blood flow into, the plantar flexors. Human subjects were fixed to a tilt table that could tilt them from the horizontal (0 degrees ) to upright (90 degrees ) position and enabled force to be applied to a footplate through isometric action of the right...

purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...

Van Beuzekom, A. D. and J.A.M. Van Gisbergen. Properties of the internal representation of gravity inferred from spatial-direction and body-tilt estimates. J Neurophysiol 84: 11–27, 2000. One of the key questions in spatial perception is whether the brain has a common representation of gravity that is generally accessible for various perceptual orientation tasks. To evaluate this idea, we compa...

The aerodynamic design and analysis of an Unmanned Air Vehicle, capable vertical take-off landing by employing fixed four rotors on the tilt-wing two tilt-tail, will be presented in this study. Both main wing horizontal tail can tilted 90°. During VTOL, transition forward flight, thrust forces have been employed. Different flight conditions, including effects angle attack, side slip, tilt contr...

Abstract One of the main goals interpretation magnetic data is imaging boundaries subsurface structures. In this study, a new edge detector called improved horizontal tilt angle (impTDX) has been introduced and tested on synthetic measured data. The filter exhibits high efficiency not only in detecting sources, but also determining sources from different depth levels. impTDX produces more preci...
