complexity is always checked in advance whether it is below a predefined threshold for providing an efficient early termination opportunity. If this early termination condition is not met, three mode types... prediction direction, to determine in advance whether the optimal prediction direction is in the temporal prediction direction or not, for skipping unnecessary disparity estimation. Experimental results......
characteristics, may impact the backfilling effect from the aspects of control of roof subsidence in advance, support stress, backfilling process and the support design. Firstly, the reason why horizontal... face deployment, roof subsidence in advance, mining height and backfilling during engineering application, the horizontal roof gap is optimized. The research results can be served as theoretical basis......
:In this paper, the recent advance of processes for treating Baotou mixed-type rare earths concentrate, bastnasite, and ionic adsorption deposit in China was reviewed. The R & D circumstance and new progresses......
-dimensional similar simulation test-bed was constructed. The stress and displacement that change along with the advance of mining were acquired and analyzed automatically by data system. The processes... the safe advance of stoping work face. Caving of safety roof puts in practice at the first two mining intervals when the third interval of continuous mining is finished, and one interval as the safety......
cathode for lithium–O2 batteries(LOBs). As a proof-of-concept experiment, the photo-initiated in situ polymerization of GPE was carried out via incorporating the precursor solution in advance......
基于ACC支付模式的两层信用支付的EOQ模型张冲,张俊,王海燕南京邮电大学管理学院东南大学经济管理学院摘 要:为了避免坏账,同时刺激下游零售商订购批量,上游供应商要求零售商采取ACC支付模式(提前支付advance,现金支付cash和延期支付credit).针对顾客资金情况,将顾客分为如下两类:第1类顾客资金充足,顾客会提前支付部分比例的货款,同时获得价格折扣,剩余货款采取延期支付的方式,这类顾客不仅享受价格折扣,同时享受延期支付策略;第2类顾客资金不足,顾客会采取部分货款货到付款,剩余货款采取延期支付的方式,这类顾客仅享受延期支付策略.构建由1个供应商与1个零售商和两类资金情况不同的顾客构成的两层信用支付供应链库存模型,证明最优解的存在性和唯一性.研究表明,零售商可以通过提高销售价格,争取更大的价格......
of solidifi cation shrinkage is analyzed. The results demonstrate that solidifi cation shrinkage delays the advance of the solidifi cation front and intensifi es the segregation.关键词:......
of inflexion appeared is in advance for thermal process of cement hydration and worsened for the structure forming process.Comparison with the control specimen,adding Na2SO4 makes the minimum critical point......
of the sample containing CaCO3 appears in advance and is higher and narrower than that of the pure sample. Key words: 3CaO?SiO2 (C3S); CaCO3; hydration performance; effect mechanism 石灰石作为水泥生产原料和混凝土的粗,细骨料......
