This investigation was completed as part of the ITS-IDEA Program which is one of three IDEA programs managed by the Transportation Research Board (TRB) to foster innovations in surface transportation. It focuses on products and result for the development and deployment of intelligent transportation systems (ITS), in support of the U.S. Department of Transportation's national ITS program plan. T...

Air brake system has been widely used in heavy trucks and intercity buses for its great superiority over other brake system. The practical performance of air brake system may be greatly different from if we analyze it with static theory. Thus, it is necessary to build an integrate air brake system model to simulate the process of brake accurately. However, the dynamic mathematic model of air br...

In this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in XU7/L3 engine. In this study, considering the strength and accuracy of simulation GT-POWER software in researches on the internal combustion engine...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Use of fuel blend in place traditionally used fossil fuel, significantly reduced carbonated emissions from internal combustion engine. Further reduction such with controlled ‘NOx yield’ is a challenge faced by researchers. Modification muffler geometry an engine while using blended helps temperature and subsequently diminish NOx formation alters CO2 emissions. This paper investigates hybrid met...

With the development of brake-by-wire system, more and advanced driver assistance systems have been applied to automobiles. The system can collect driver’s braking intention through displacement sensor thus realize accurate by motor. Based on we design an algorithm that vehicle Comfort Stop Technology (CST) in this paper. CST control drop rise brake fluid pressure during stop vehicle, therefore...

purpose: to compare the short and long-term efficacy and complications of releasable suture vs conventional interrupted suture for scleral flap in trabeculectomy. methods: in a prospective randomized clinical trial, 42 eyes of 42 consecutive patients requiring trabeculectomy for uncontrolled primary glaucoma underwent conventional trabeculectomy (group a) and trabeculectomy with releasable sutu...
