in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...
Purpose: The aim of this survey was to evaluate the effects of fatty acids, nutrients and vibration on bone mechanical properties and its metabolic parametr’s in rat.Materials and Methods: 56 male wistar rats weighting 150±30 were used. Rats divided into control and six experimental groups as below: Vibration, Vibration+nutrients, Vibration+nutrients+ Canola oil, Sunflower oil, Canola oil+Sunfl...
In multiperiod stochastic optimization problems, the future optimal decision is a random variable whose distribution depends on parameters of problem. I analyze how expected value this changes as function dynamic in context Markov processes. call analysis comparative statics. derive both statics results and showing current decisions change response to single-period payoff function, discount fac...
