Background: Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess the personal and environmental noise level and project the sound map of an Iranian tire manufacturing complex using Surfer V.14 and Noise At Work tools. Materials and Methods: This descriptive study was conducted in the curing hall [including curing, sandblast,...

This paper discusses the development of a deformable terrain database to be used in a co-simulation environment with a multibody dynamics vehicle model. The implementation of the model includes a general tire-terrain traction model which is modular to allow for any type of tire model that supports the Standard Tire Interface[1] to operate on the terrain. Rather than utilizing empirical terramec...

the natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. tire rubber materials and cord layers are represented independently using “shell element” available in cosmos. the effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural fre...

Following recent studies, the automatic analysis of intracranial pressure pulses (ICP) seems to be a promising tool for forecasting critical intracranial and cerebrovascular pathophysiological variations during the management of many neurological disorders. MOCAIP algorithm has recently been developed to automatically extract ICP morphological features. The algorithm is able to enhance the qual...

Introduction IV-VI compounds are regarded as average group V material. In crystalline group V elements and IV-VI compounds, the Peierls distortion occurs. Strong bonds with short bond length and relatively weak bonds with long bond length coexist in the crystal. Therefore anisotropic contraction of the local structure is expected under pressure [1]. In crystalline SnSe, atoms form two dimension...

Despite tremendous progress in the understanding and management of hypertension, control of elevated blood pressure (BP) in the general hypertensive population remains unsatisfactory, with only an approximate one third of patients 1 achieving the recommended BP goals. Consequently, cardiovascular risk as a result of target organ damage, notably in the heart, kidneys and brain remain high among ...

Complex flow features within rocket nozzles can exert significant influence on both the dynamics and safety of rockets during flight. Specifically, under over-expanded flow conditions, during, low altitude flight, random, often large side loads can appear within nozzles. While significant research has focused on this classical problem, due to the high nozzle pressure ratios (NPR) extant across ...

Low arterial pressure* (Hypopiesis) is a term applied to low arterial pressure in general, whether physiological or pathological, temporary or permanent, congenital or acquired. Hypopiesia (primary low arterial pressure) is a clinical series of primary congenital, constitutional or familial origin, characterised by persistently lowered arterial pressure occurring as a part of a low vitality sta...

The tire pressure monitoring system (TPMS) can not only make the driver more safety, but also save fuel and protect the tire. Tire safety is attracting the driver's attention, the United States had developed laws to enforce the TPMS installation in the car. In this paper, the basic structure and the implement method of TPMS are introduced. The SAW theory and some surface acoustic wave (SAW) tem...
