夏天的天气简直熱得都快要赶上e浪潮了,让e诸葛实在有点不受用。于是乎,e诸葛抽了个空到大商场去查探了一番。虽然这不是一个大老爷们愿意干的事,但是既然是“微服私访”,就有几个原因:一是想吹吹空调,吸吸凉气,驱走烦躁;二是想在商场中找寻一些关于传统零售业迟迟不肯进入电子商务的蛛丝马迹。走了走大商场.他好象明白了其中一二。都说“购物是一种享受”,大概只有抱着研究的心态,e诸葛才注意到:商场中不但有凉爽的环境、柔和的灯光、优美的音乐,就连货物的摆放、位置也有讲究。似乎大型商场一层总是化妆品和首饰,二、三层铁定是男装女装,超市嘛,肯定在地下……这就是传统商家的一些经验吧。有层次感、丰富多样的物品加上员工的服务态度……加在一起 相似文献

对于每一个人来说,“小人”都是一个极端的蔑称。所谓“两面三刀、阳奉阴违”,人人都敬而远之,古龙在其书中说到,他最痛恨的就是“嘴里叫哥哥,手里捅刀子”的家伙。猫王的一位朋友就曾有感而发:“千万不要轻信那些表面的现象,也不要被那些甜言蜜语所迷惑,不了解实际情况决不能轻易下手。那些奸商……”朋友很是愤怒,因为他受过骗。那年,他要买打印机,“就想买个耐用的,便宜点的。”于是,这老兄四处查找信息,终于在某杂志上找到他所中意的对象,便宜、耐用、不偏不倚。朋友打电话去询问,销售小姐很热情,各项情况娓娓道来,并保证广告所说一切属实,敬请现场查看。朋友一时喜不自禁,第二天就驱车前 相似文献

初遇Hero,是在I社区里,那时候自己刚到这家公司,对各种图片软件一窍不通,而主编交给我的一大堆任务全跟那些PHOTOSHOP,DREAMWEAVER什么的有关,我看着它们,这里改改,那里改改,都不得要领,简直被他们弄得焦头烂额了。于是百无聊赖之际,走走停停地就来到I社区,开始以为这不过是个供人扯淡的茶庄,谁知才说了一两句话就发现这里高手如 相似文献

处理机的指令级并行能力只有通过编译器才得以发挥。代码生成是编译器后端中直接针对目标处理机的优化阶段的集合,因而它是提高目标处理机指令级并行的重要组成部分。ORC(Open Research CompiLer)是一款针对IA-64体系结构的开放源码编译器,它具有丰富的优化阶段和良好的性能。本文介绍了ORC的代码生成的关键技术,这些技术包括区域构造、谓词相关优化、全局指今调度、参数化的机器描述以及微调度。实测结果表明,这些技术取得了显著的优化结果,ORC相对于Pro64能取得平均23%的加速比。 相似文献

The Au-Ni nanoparticles (NPs) were prepared by oleylamine solvothermal synthesis from metal precursors. The Au-Ni phase diagram prediction respecting the particle size was calculated by the CALPHAD method. The hydrodynamic size of the AuNi NPs in a nonpolar organic solvent was measured by the dynamic light scattering (DLS) method. The average hydrodynamic sizes of the nanoparticle samples were between 18 and 25 nm. The metallic composition of the AuNi NP samples was obtained by inductively-coupled plasma atomic emission spectroscopy (ICP-OES). The metallic fraction inside AuNi NPs was varied Au-(30–70) wt%Ni. The steric alkylamine stabilization was observed. The individual AuNi NPs were investigated by transmission electron microscopy (TEM). The dry nanopowder was also studied. The structures of the aggregated samples were investigated by scanning electron microscopy (SEM). The AuNi NPs reveal randomly mixed face-centered cubic (FCC) crystal lattices. The phase transformations were studied under inert gas and air. The samples were studied by differential scanning calorimetry (DSC). 相似文献

Simulation of partially observed Markov decision process and dynamic quality improvement 总被引:1,自引:0,他引:1
Computer simulation is used to compare three quality policies. The first policy is ‘do-nothing’. The second is an appraisal policy. The third policy includes prevention that leads to process quality improvement. The simulation model is based on a Partially Observed Markov Decision Process (POMDP). The unobserved states of the process depend on the failure rate, λ. The observed process output is the number of conforming and nonconforming products. The process performance is measured by quality costs per unit. The simulation language used is SLAM II. The power of using computer simulation to model the dynamics of process quality improvement is discussed. 相似文献

The present paper deals with the variational approach for solving a clamped rectangular plate under a uniform load. The increasing use of composite materials for plate-type structures intensified the need for solutions of rectangular plates. The variational approach has a broad range of applications in solid mechanics. The methods used to solve the problem consider the minimum total potential energy approach. The maximum deflection is obtained for a square plate by the Ritz, Galerkin and Kantorovich methods. The aim of this paper is to find an approximate solution of higher accuracy. Numerical results for various components of stresses are found and plotted in the form of curves. The results obtained by various methods are compared with those reported earlier. The results show reasonable agreement with the known results, but with a simple and practical approach. The physical aspect of the concept is the immediate use of these results in solid and structural mechanics. 相似文献
