基于帧间预测的HEAC-X搜索算法

无线传输、移动端技术的发展,掀起了移动视频监控系统的热潮。由于无线网络传输带宽的限制、视频在网络传输中需要大量流量,导致无法实时传输、高流量消费等问题,因此,视频在网络传输中必须压缩。该文从帧间物体运动相关性理论为出发点,提出了HEAC-X算法,以六边形块确定首次搜索范围,随后以六边形中心点组成的对角线四点为中心的菱形细化搜索算法,有效确定运动矢量,减少视频传输所占带宽,有效的对视频进行了压缩。

Window Air Conditioners Transition and Restriction in Saudi Arabia

This paper will provide a proposed solution for saving energy consumption due to residential air conditioners by reducing the window air conditioners type which is the most consumed energy and has a big percent of spreading inside KSA than the split type, also it will discuss some restrictions for trading and manufacturing of air conditioner devices inside KSA besides some restrictions on market and buildings to achieve the objective of reducing the consumption of energy which become a big trend in kingdom vision 2030. The results of this suggesting solution will help the decision-makers to start its plan for execution as it has a big difference between using window type from 2022 till 2030 and if we stop its sales and replace by an efficient one of split AC type in energy consumption in addition to CO2 emission reduction and decreasing of energy cost, hence our kingdom can save petroleum raw materials and keeping the environment to become clean from pollutants so that these resources are delivered to successive generations correct and clean as we received them from those before us.

H13钢表面激光熔覆AlCoCrFeNiW_(x)高熵合金涂层及其性能

以热作模具钢H13作为基体,通过激光熔覆制备AlCoCrFeNiW_(x)(x=0,0.5)高熵合金涂层,并研究W元素的添加对其组织结构以及热稳定性和耐磨性的影响。激光熔覆AlCoCrFeNiW_(x)高熵合金涂层相组织结构随W元素的添加会发生变化,W的添加会促进BCC相的形成,并且在晶界处形成富含W的第二相,其生长方向会沿着冷却方向形成细长状的枝晶,这些第二相会起到耐磨和强化涂层的作用。经800℃长时间保温后测试AlCoCrFeNiW_(x)高熵合金涂层的热稳定性。结果表明,AlCoCrFeNiW_(x)高熵合金涂层均能够保持较高的硬度和耐磨性,14 h保温后的硬度仍大于400 HV0.2,加入W元素后的涂层抗回火软化能力更强,800℃保温14 h后的耐摩擦磨损性能是基体的两倍以上。
