in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...
Objectives: The purpose of this study was to investigate relationship between body composition indices with static and dynamic balance and rate of falling in active elderly people. Methods & Materials: This research was a correlation study. Active elderly women volunteered for participation in this research (n=45). Body composition indices (body fat mass, fat free mass, body mass index, wais...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
Cortical control of the sensory output of muscle spindles was studied in thirteen anesthetized cats in the present experiment. Gamma motoneuron activity was monitored during electrical stimulation of the sensorimotor cortex while recording from single primary afferents from the tenuissimus muscle. Findings are as follows: 1. The state of anesthesia is crucial in obtaining reproducible resu...
this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...
در این پایان نامه متر های ریشه -mام انیشتینی را مورد بررسی قرار داده و نشان می دهیم که اگر f یک متر انیشتینی ریشه -mام باشد ، یعنی ric=(n -1 ) kf*f که در آن k یک تابع اسکالر می باشد ،آنگاهk=0 لذا ric=0. همچنین این خاصیت را برای متر های ریشه m-ام انیشتن ضعیف شده مورد بررسی قرار می دهیم. لازم به ذکر است مطالب ذکر شده از مقاله زیر است: y. yu and y. you, on einstein m-th...
The aim of this study was to determine the effect of weight transfer training on static and dynamic balance of older women. 20 accessible subjects that met our criteria divided randomly into two experimental and control groups. The experimental group trained for 6 weeks, 3 times a week and each session 60 minutes a day. Biodex balance system used for training and testing procedures. Data analys...
the aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. for this purpose, 45 old subjects agedbetween 60 and 70 from qom province participated in this study. static balancetask (stand on one leg) and dynamic balance task (sebt test) were instructed withno...
Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Me...
Background and aims: Process systems due to processed under severe operational conditions and deal with large amounts of flammable and explosive materials have always led to many catastrophic accidents. Risk assessment is a useful tool for designing effective strategies for preventing and controlling these accidents. Conventional risk assessment methods have major deficiencies, including uncert...
