ABSTRACT The quality of ride is predominantly controlled by the design of the secondary suspension in rail vehicles. That is why air springs are increasingly important suspension component in rail vehicles. This is necessary for higher preload, higher speed as well as improved ride dynamics and noise levels. These necessities have created an interest for modeling the air springs for the simulat...
In this paper, for the first time, a comprehensive experimental study is performed on hydroforming process of metallic bellows. For this purpose, the effects of the main process parameters and their interactions on the characteristics of hydroformed metallic bellows are investigated using Response Surface Methodology (RSM). The selected parameters as input variables are internal pressure, die s...
air pollution in industrial and urban areas is one of the most important problems of environment which endangers humans' health; an example of these pollutants is the suspended particles in the air that with the increase of 10 in the air, the rate of mortality increases by 1 to 3 precent. this study was done during three seasons by determining ten sampling stations in each season and according ...
Introduction: In recent decades, with the emergence of new industrial activities and increase production of waste production, industries require the existence of treatment equipment and sanitation. These devices sometimes spread infectious microorganisms into the air. These include waste recycling industries and wastewater treatment plants. Bioaerosols are produced at different stages of the wa...
Two-point boundary value problems for conservative systems are studied in the context of the least action principle. One obtains a fundamental solution, whereby two-point boundary value problems are converted to initial value problems via an idempotent convolution of the fundamental solution with a cost function related to the terminal data. The classical mass-spring problem is included as a si...
We developed a model to demonstrate how a hopping kangaroo breathes. Interestingly, a kangaroo uses less energy to breathe while hopping than while standing still. This occurs, in part, because rather than using muscle power to move air into and out of the lungs, air is pulled into (inspiration) and pushed out of (expiration) the lungs as the abdominal organs "flop" within the kangaroo's body. ...
frost is one of the atmospheric phenomena which seriously threaten crop production. it also causes numerousaccidents in mountainous roads. in this research the spatial synoptic classification ssc method was employed toclassify the type of air masses. for the classification, such meteorological data as: temperature, dew point, mean sealevel pressure, cloudiness, direction and speed of wind were ...
