Abstract There is a large amount of medium and low frequency noise in the interior certain vehicle type under constant speed driving conditions. Through identifying source, it determined that mainly caused by road noise. The suspension rubber bushing, mounting inching stiffness, body sheet metal are optimized, reduced 3 to 5 dB (A).

The luminol test for blood was carried out on a set of interior fittings and surfaces inside three different makes of modern motor car. The surfaces and fittings provided little interference with the test for blood, although there was some detectable chemiluminescence when the test was applied to blood-free material from a seatbelt, a boot-lining and a gear-knob. The case with which haemoglobin...

we present a modified version of the infeasible-interior- we present a modified version of the infeasible-interior-point algorithm for monotone linear complementary problems introduced by mansouri et al. (nonlinear anal. real world appl. 12(2011) 545--561). each main step of the algorithm consists of a feasibility step and several centering steps. we use a different feasibility step, which targ...

An infeasible interior-point algorithm for mixed symmetric cone linear complementarity problems is proposed. Using the machinery of Euclidean Jordan algebras and Nesterov-Todd search direction, the convergence analysis of the algorithm is shown and proved. Moreover, we obtain a polynomial time complexity bound which matches the currently best known iteration bound for infeasible interior-point ...

Road traffic accidents account for approximately 3000 deaths on a daily basis, and 50 million injuries and 1.2 million deaths each year. In low-income and middle income countries, road traffic accidents account for 85% of deaths and 90% of annual disability. Casualties of this magnitude are a serious problem throughout the world and create a significant impact on society. In addition, neurologi...

this study is to report characteristics of people killed in road traffic crashes and to describe major patterns of traffic crashes in china.descriptive and inferential statistical analyses were conducted. road traffic death national data, population denominator data and motor vehicles data of 2009 were obtained from the bureau of traffic management at ministry of public security and national bu...

in this paper, we deal to obtain some new complexity results for solving semidefinite optimization (sdo) problem by interior-point methods (ipms). we define a new proximity function for the sdo by a new kernel function. furthermore we formulate an algorithm for a primal dual interior-point method (ipm) for the sdo by using the proximity function and give its complexity analysis, and then we sho...

Road Traffic injuries are known as the most prevalent childhood injury and besides being the greatest cause of child mortality, place an extraordinary burden on health care system. Children’s limitation in cognitive, physical and social development makes them more vulnerable in road traffic injuries than adults. Their small structure cause challenges to see and be seen and their risk taki...
