The lubrication performance of journal bearings with different sorts of uniformly distributed micro-spherical textures are studied in this paper.Geometries and dynamic models of journal bearings with pure concave/convex textures are developed.The validity of the proposed models is verified against the oil film pressure distribution from the literat
Flutter analysis is considered for the minimum altitude at which the minimum designed Mach number is achieved, for the maximum altitude at which the maximum designed dynamic pressure superdry baseball top is obtained and for the minimum altitude at which transonic effects begin occurring.Moreover, analyzes is performed color block iphone case for a
Nanoscopic materials have demonstrated a versatile role in almost every emerging field of research.Nanomaterials have come to be one of the most important fields of advanced research today due to its controllable particle size in the nanoscale range, capacity to adopt diverse forms and morphologies, high surface area, and involvement of transition
Cheleleka peatland is located at the eastern side of Lake Hawassa and its biological communities read more face a variety of anthropogenic factors such as agricultural expansion, water diversion, settlement and subsequent peatland drainage and peat extraction.The decomposing products were influenced by various anthropogenic activities.This study ai
With the continuous and rapid growth of electric vehicle (EV) ownership, a large number of disorderly charging loads accessed to the regional grid may lead to problems such as widening of the peak-to-valley load difference and deterioration of power quality.This study proposes an optimal EV charging and discharging regulation strategy based on dyna
