this study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. after incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. there was a significant (p

" استاپ موشن" (stop motion) یا انیمیشن ایست – حرکتی یکی از تکنیک های ساخت انیمیشن که در آن با استفاده از فیلمبرداری فریم به فریم اشیاء فیزیکی را به حرکت در می آورند و از پشت سر هم قراردادن تصاویر این حرکت های فریم به فریم، تصور حرکت القا می شود. "موشن گرافیک" (motion graphic) نیز یکی دیگر از تکنیک های ساخت انیمیشن است. این تکنیک با استفاده از تکنولوژی ویدئو و با ایجاد توهم حرکت یا تغییر در ظاهر...

stability and performance are two main issues in motion of bipeds. to ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. however, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. step length and step perio...

We show that the large corrections due to final state interactions (FSI) in the D+ → π−π+π+ , D+ s → π−π+π+ , andD+ → K−π+π+ decays can be accounted for by invoking scattering amplitudes in agreement with those derived from phase shifts studies. In this way, broad/overlapping resonances in S-waves are properly treated and the phase motions of the transition amplitudes are driven by the scatteri...

The aim of this dissertation is to study stochastic Navier-Stokes equations with a fractional Brownian motion noise. The second chapter will introduce the background results on fractional Brownian motions and some of their properties. The third chapter will focus on the Stokes operator and the semigroup generated by this operator. The Navier-Stokes equations and the evolution equation setup wil...

In this research we design a passive controller for an above knee prosthesis. The controller is a linear spring and damper for swing phase motion, parameters of which determined via optimization of adjustment of the prosthesis shank motion with a desired shank angle trajectory comes from experimental data. In this way, we exerted a certain thigh motion, hip movement included, into the system as...
