In the current study, numerical analysis of passive control flow with a rod for Ahmed body is performed at different slant angles and velocities placed locations on surface. The aim study to improve aerodynamic performance by preventing separation surface using rod. This method uses that has not been applied simplified ground vehicles before. Therefore, it can be said this new example in point ...
Excessive vibration can be detrimental to the structural integrity of structures or can adversely affect the performance of instruments such as telescopes or antennas. One field in Structural Dynamics is the design and application of systems that reduce the amplitude and duration of vibration. There are two types of vibration suppression systems: passive and active. Passive means that the dampi...
This paper introduces a novel passive suspension system for ground vehicles. This system is based on a flexible Electromagnetic Shock Absorber (EMSA). In the proposed system, efforts are made to a) select a high damping coefficient usable in a car b) determine Physical dimensions and geometry not much different from those of the mechanical shock absorbers and c) seletct EMSA weight and volume l...
background : few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. the purpose of this study was to determine threshold levels of meningitis outbreak in hamadan province, west of iran . methods : data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 march 2010 to 20 march 2012 were use...
evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
abstract this paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. the proposed algorithm is expanded by using multiobjective optimization schemes. the objectives to be optimized in this paper are determined so as to reduce the sinr fluctuations as well as maintaining the sinr to an acceptable level with minimizing an average tra...
