The simulation of the store separation using the automatic coupling of dynamic equations with flow aerodynamics is addressed. The precision and cost (calculation time) were considered as comparators. The method used in the present research decreased the calculation cost while limiting the solution error within a specific and tolerable interval. The methods applied to model the aerodynamic force...
in order to help in the engineering design of rice harvesting machines, there is a need to have exact information concerning the physical and mechanical properties of rice stems. the cutting force for rice stems, therefore, was measured by designing and fabricating a static and dynamic shear test apparatus. the effects of moisture levels and the cross-sectional area of stem as well as the varie...
objectives: the aim of current study was to determine the effects of hata yoga training on dynamic and static balances of elderly women in mashhad. methods and materials: the present study enjoys the semi-experimental design. the statistical population of the study, which has been carried out in 2009, were elderly women of mashhad who were voluntarily invited to participate in the research. 29 ...
A Framework for Adapting Population-Based and Heuristic Algorithms for Dynamic Optimization Problems
In this paper, a general framework was presented to boost heuristic optimization algorithms based on swarm intelligence from static to dynamic environments. Regarding the problems of dynamic optimization as opposed to static environments, evaluation function or constraints change in the time and hence place of optimization. The subject matter of the framework is based on the variability of the ...
Comparison of the Effect of Dynamic and Static Splints on Wrist Spasticity in Post-Stroke Patients J. Eghlidi [1] , D. Elyaspour [2] , S.M. Tabatabaee [3] , A.A. Jamehbozorgi1, F. Farshchi [4] , M. Heidari [5] Received: 10/04/26 Sent for Revision: 08/06/10 Received Revised Manuscript: 02/10/10 Accepted: 09/10/10 Background and Objectives: Among several methods which are accessible...
Introduction: Implant restorations should endure a variable range of forces over long period time. Some commercial brands offer the implant together with an accessory called “implant mount” or holder,” which might be used as temporary abutment. However, scientific literature in use holders abutments for is scarce.Objectives: The purpose this vitro study was to compare load at Direct® and Zimmer...
Objectives: The aim of present study is to determine the effect of two methods of aerobic training on static and dynamic balance in old men. Methods & Materials: 37 aged people over 60 years old who were physically healthy divided into three groups after randomly carrying out pretest: 1) walking or running aerobic exercise group (n=12), 2) cycling aerobic exercise group (n=13) and 3) c...
Objectives: After age of 65, annually 10 percent of older adults> loss their independent in one or more daily task. Because of decreasing changes in neuromuscular system that is important factor in loss the balance and walking ability in this group of people. In according to these sentences, the aim of this research was to the comparison of mental, physical and mixed practices on static and dyn...
Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...
