To study the lubrication characteristics of grease-lubricated rolling ball bearings, such as film thickness and pressure variations in elastohydrodynamic lubrication with elliptical point contact, a numerical analysis model of elastohydrodynamic grease lubrication is firstly constructed.This model is based on the Herschel-Bulkley rheological model
In this paper, we are concerned with data pertinent to transportation networks, which model situations in which objects move along a graph-like structure.We assume that these networks are equipped with sensors that monitor the network and the objects moving along it.These sensors Bosch BFL553MS0B Serie 4 900 Watt Microwave Built In Stainless Steel
In this study, five groups of numerical models with different conditions were established by using PFC2D (particle Dresser and Mirror flow code) to simulate the direct shear tests of noncoplanar nonthrough jointed rock mass.It is proved that normal stress and shear rate, as well as the connectivity rate, relief angle, and inclination angle of joint
One dimensional nanostructures, like nanowires and nanotubes, are increasingly being researched for the development of next generation devices like logic gates, transistors, and solar cells.In particular, semiconducting nanowires with a nonsymmetric wurtzitic crystal structure, such as zinc oxide (ZnO) and gallium nitride (GaN), have drawn immense
Abstract Background In radiotherapy, minimizing the time between referral and start of treatment (waiting time) is important to King Set possibly mitigate tumor growth and avoid psychological distress in cancer patients.Radiotherapy pre-treatment workflow is driven by the scheduling of the first irradiation session, which is usually set right after
