  • DevOps研习社:品质决定成败——漫谈非功能性需求

    在互联网的世界里,“用户就是上帝”这句话只体现在支付环节。而在日常生活中,几乎每一个人都清楚的知道,不论是产品还是服务,品质决定竞争力,而对于一个软件、应用或者App来说,功能是生命线,确定能否安身立命,而非功能需求则是它的品质。一个软件、应用或者App的特性表现在两个方面,功能性与非功能性。功能性好理解,硬指标,开发过程中的里程碑,一定要啃下的山头,而非功能性需求更偏“软”,如App好不好用,速度快不快,设计是否反人类等。在我们的日常生活中,非核心、非会员,只要带了一个“非”字,往往都不是那么重要的,可不能因为非功能性带了一个“非”字就常规鄙视它,。在遥远的古代(10年前),IT市场上的物资

  • Flexible resource allocation adaptive to communication strategy selection for cellular clients using Stackelberg game

    In cooperative communication Networks (or cooperative cognitive radio networks), a source node usually recruits non-altruistic relays to execute cooperative communication with a target node, through compensating these potential relays with a fraction of its licensed frequency band. When a source node is far apart from a target node, it is difficult to achieve the desired transmission performance by cooperative communication. In this paper, a source node's communication strategy can dynamically b

  • Anti-resonant reflecting guidance in alcohol-filled hollow core photonic crystal fiber for sensing applications

    Mechanism and sensing applications of antiresonant reflecting guidance in an alcohol-filled simplified hollow-core (SHC) photonic crystal fiber (PCF) are demonstrated. By filling one air hole in the air cladding of the PCF with alcohol, anti-resonant reflecting guidance of light can be achieved and energy leakage of the core modes can be induced at resonant wavelengths of the Fabry-P´erot (F-P) resonator formed by the alcohol-filled layer combined with the silica cladding in the cross-sect

  • 如何用Axure快速制作APP交互原型

    对于产品经理来说,熟练使用一些常用软件是一项十分必要的技能。其中,作为一个专业的快速原型设计工具,AxureRP无疑在产品人心中拥有一个难以撼动的地位。但就要PS一样,虽然足够专业,但同样也会存在使用灵活性的一些问题。今天我们就谈谈,如何用Axure快速制作APP交互原型,不对,更准确的说法应该是:如何用Axure快速制作一份有水准的APP交互原型。作为一名优秀的产品人不仅要保证效率,也要保证质量才行。首先抛出我的方法论:制作属于自己的元件库并要学会善用母版,熟悉APP设计规范并要有自己一套交互风格样式。我会以仿照「读读日报」IOS版做的一个交互原型稿为实例,表述整个制作过程的思路,希望能对你

  • 测试工程能力容器化改造方案

    随着容器时代的到来,开源社区中诞生了以Docker、Rocket为代表的优秀的容器引擎方案。本文旨在介绍通过容器技术对不同测试类型(应用层测试、中间层测试、内核测试、硬件驱动测试、编译测试)进行容器化改造的方案和收益,并通过具体实例的方式来展示容器化时代为软件测试带来的机遇。容器时代为云产业带来了前所未有的机遇,容器云平台如雨后春笋般的出现在大家的视野中。大部分容器云都提供了代码托管、镜像存储、编译、测试、打包、运维等功能。容器云中的容器通常配置有一致的内核,相近的硬件资源。很多的软件测试任务可以通过容器云进行改进或加速。然而,还有一些类型的测试任务不适用容器云。需要说明的是容器云和容器是两个

  • Light transmission in porous silicon dioxide filled with liquids of different refractive indices

    Optical transmission at 532 nm from nonabsorbing disordered porous silicon dioxide has been studied experimentally. The transmission behaviors can be adjusted by filling the pores with liquids of different refractive indics, which are analyzed based on the theory of diffusion in a weak scattering regime. In our experiment, the transmission coefficient changes from a value less than 1% to one that is greater than 75%, that is, the opaque sample becomes transparent, which means that the transport

  • Electron impact total (elastic + inelastic) cross sections with simple molecules consisting of N & O atoms at 100 - 1600 eV

    A model complex optical potential rewritten by the conception of bonded atom, which considers the overlapping effect of electron cloud, is employed to calculate the total (elastic + inelastic) cross sections with simple molecules (N_(2), O_(2), NO_(2), NO, N_(2)O) consisting of N & O atoms over an incident energy range of 100 - 1600 eV by the use of additivity rule at Roothaan-Hartree-Fock level. In the study, the complex optical potential composed of static, exchange, correlation polarization p
