gears are one of the most critical components in power transmission system of an automobile and also many rotating machinery. many studies have been conducted on optimum gear design. the main objective is to design different aluminium metal matrix composite spur gears before and after optimization. aluminium metal matrix material composites are preferred mostly due to their low density. also th...
The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity. In this work, the di...

Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...
[1] Recent spectroscopic detections of CH4 in the atmosphere of Mars are the first definitive observations of an organic compound on that planet. The relatively short photochemical lifetime of CH4 ( 300 years) argues for a geologically young source. We demonstrate here that lowtemperature alteration of basaltic crust by carbon-bearing hydrothermal fluid can produce the required CH4 flux of 1 10...
[1] The Kaoiki Seismic Zone at Mauna Loa’s east flank is the locus of some of the largest earthquakes on Hawaii. In this paper we examine the link of those earthquakes to volcanic activity at Mauna Loa. We calculate the changes of Coulomb failure stress along the Kaoiki faults for typical volcanic events at Mauna Loa volcano. We simulate the dislocation associated with the 1950 eruption at the ...
More and more natural disasters are happening every year: floods, earthquakes, volcanic eruptions, etc. In order to reduce the risk of possible damages, governments all around the world are investing into development of Early Warning Systems (EWS) for environmental applications. The most important task of the EWS is identification of the onset of critical situations affecting environment and po...
طراحی PLL دو حلقه ای مبتنی بر آشکارسازی فاز پنجرهای با سرعت قفل بالا، توان مصرفی و اسپور مرجع پایین
In this paper, a dual loop PLL with short locking time, low power consumption and low reference spur is presented. The output frequency and reference frequency of the designed circuit are 3.2 GHz and 50 MHz, respectively, aimed to WiMAX applications. In the proposed circuit in locked state, some parts of the circuit could be powered off, to reduce overall power consumption. Phase detection in t...
