This paper studies modeling of tangential compliance as two rigid bodies collide in the space. Stronge’s spring-based contact structure [13, pp. 95-96] is extended to three dimensions. Slip or stick is indicated by the tangential motion of a massless particle connected to the contact point (viewed as an infinitesimal region) on one body via three orthogonal springs. We show that the effect of t...
Stability and performance during rhythmic motor behaviors such as locomotion are critical for survival across taxa: falling down would bode well for neither cheetah nor gazelle. Little is known about how haptic feedback, particularly during discrete events such as the heel-strike event during walking, enhances rhythmic behavior. To determine the effect of haptic cues on rhythmic motor performan...
The present study analyzed the effect of increased distance on basketball jump shot outcome and performance. Ten male expert basketball players were filmed and a number of kinematic variables analyzed during jump shot that were performed from three conditions to represent close, intermediate and far distances (2.8, 4.6, and 6.4m, respectively). Shot accuracy decreased from 59% (close) to 37% (f...
Several scenarios used in teaching feature a rolling motion with slipping that transitions to one without through friction the ground. We summarise these by introducing an unknown impulse is transferred Accounting for this conservation of angular and linear momentum, we can deduce final state compact manner requiring details friction. Contrasting technique explicit calculation illustrates how c...
impulse buying is a significant aspect of consumer behavior and a critical concept in the marketplace. dramatic increases in consumption and possibility of credit buying all over the world has provided appropriate situations for impulse buying, however there is little information about impulse buying in eastern and in transition societies and economies. the purpose of this study is to develop a...
the aim of this research work was to investigate on the ball filling estimation of miduk semi-autogenous (sag) mill via an utilized method. miduk copper concentrator is located in kerman province, iran, and its size reduction stage includes one gyratory crusher which feeds one sag mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). after sag mill, a tromm...
Using the mathematical aspects of Schwarzschild metric, we present different variables transformation which proves that central singularity hypothesis does not exist. The geometric interpretation black hole from metric is mathematically convincing. approaches taken by many authors were viewed, such as Painleve and its complex variant, to deduce a with throat sphere leads mirror space-time. Subs...
مقدمه: به علت مشکلات دنچرها، امروزه اوردنچرهای متکی بر ایمپلنت رواج یافتهاند. به رغم موفقیت بالای ایمپلنت، از دست رفتن ایمپلنت هنوز معضل اساسی است. افزایش نیروی وارد بر ایمپلنت فاکتور مهم تحلیل استخوان و از دست رفتن ایمپلنت میباشد. این مطالعه با آنالیز اجزای محدود اوردنچرهایی با سه ایمپلنت، به بررسی بهترین طراحی و ترکیب اتچمنت که باعث حداقل استرس در استخوان آلوئول شود، پرداخته است. مواد و روش...
