Vehicle dynamic analysis has been a hot research topic due to its important role in ride comfort, vehicle safety and overall vehicle performance.. For proper designing of suspension system, nonlinearities in suspension parameters must be considered. In this paper, nonlinearities of spring and damper are considered while preparing quarter car model. For this a simplified model and experimental s...

Present work aims at developing an active suspension for a passenger car by designing a controller using linear quadratic optimal control theory, based on two different control approaches [conventional method (CM), acceleration dependent method (ADM)]. Performance of the active suspension system of a quarter car model with 3 degrees-of-freedom with two control approaches has been compared with ...

The on-going RSSB/EPSRC UK SafeCap project develops modelling techniques and tools for improving railway capacity while ensuring that safety standards are maintained. This paper reports recent SafeCap results on designing a Domain Specific Language (DSL), a verification infrastructure and the approaches to estimating and improving capacity. © 2012 Newcastle University.

Vehicle traffic is responsible for the resuspended road dust. Substantial fraction of PM10 in urban air is mainly due to non-exhaust traffic emissions and resuspension from street surfaces. These road non-exhaust emissions are often uncontrolled and information about the effectiveness of mitigation measures on paved roads is still scarce. The present work is aimed to design a dust collector sys...

BACKGROUND Much of the research into cyclist safety in Australia has focused on behaviour with less focus on the impact of the urban transport environment on cyclist safety. A greater understanding of the urban transport system and the improvements needed to create a safer cycling environment are essential if cyclists are to be safe and increased cycling participation targets are to be achieved...

Today, the problem of designing suitable multiprocessor architecture tailored for a target application field raises the need for a fast and efficient multiprocessor system-on-chip (MPSoC) design environment. Additionally, the implementation of image processing applications on MPSoC system will need to exploit the parallelism and the pipelining in algorithms with the hope of delivering significa...

spinal cord injuries (sci) are highly disabling and injuries. this study aims to describe the demographic and epidemiologic data on auto accident patients who were admitted at khatam alanbia hospital. the results obtained from 73 sci patients treated on the sci inpatient units of the khatam alanbia hospital (from march 2009 to march 2013) were evaluated retrospectively. then patient gender, age...

road traffic accident (rta) is a global burden of disease. more than 1.25 million people per year are killed by rtas. more than half of the fatalities strike vulnerable road users (e. g. pedestrians, skaters, cyclists and other non-protected road users). the ongoing challenge is to protect vulnerable road users (vru). as a vru is neither shielded by seatbelts or crumple zones nor by airbags, th...

the optimum road spacing has been studied by many researches. it is an important step of forest road network planning. the goals of this study are determining the optimum road spacing in kheiroudkenar forest of nowshahr in northern iran and study of effect of kind of skidder on skidding cost and road spacing. continues time study method was used to determine the production rate of taf and timbe...
