The collision smearing of the nucleon momenta about their initial values during relativistic nucleus-nucleus collisions is investigated.To Nail Scissors a certain degree, our model belongs to the transport type, and we investigate the evolution of the nucleon system created at a nucleus-nucleus collision.However, we parameterize this development by

Abstract Local tri-directional pattern (LtriDP) is a method of extracting local intensity features from each pixel based on direction.However, this method has not been able to provide good performance in extracting features for image retrieval.One reason that makes image retrieval performance worse is the effect of lighting.Lighting can cause large

Abstract With the advantages of its fast speed, effective and moderate controllable conditions, desulfurization of coal by microwave has become research focus in the field of clean coal technology.Coal is a homogeneous mixture which consists of various components with different dielectric properties, so their abilities to absorb microwaves are diff

Owing to the increasing energy demand, producing more oil from the residual in the old reservoir by water flooding and enhanced oil recovery (EOR) methods should be considered.Water flooding has become the most widely used process by injecting water into the reservoir to displace oil.The chemical EOR is a chemical injection into the reservoir.When

In order to accurately calculate the meshing efficiency of the Power Inlet new internal S-gears, a time-varying friction model of the elastohydrodynamic lubrication is established considering the surface sliding of the gear tooth, lubricating oil condition and load.The lubrication mechanism of the meshing tooth surface is analyzed, and the sliding
