关于“云消费”基本特征的研究

当前我们已经进入一个全新的以消费者为核心的商业时代——“云消费”时代.“云消费”在技术层面上表现为三大基本特征,即体现云消费发展内涵和容量的“云内容”,代表云消费终端平台的“云终端”,反映云消费的交易形式和支付方式的“云支付”.本文对此进行了较全面的研究.     

变风量空调系统风机风量控制方法研究与实现

变风量空调系统运行的不稳定以及新风等问题是影响变风量空调系统性能的主要原因.通过对我国变风量空调系统所采用的几种主要控制方法进行优劣分析,结合末端风阀状态反馈,提出了一种新的控制方法:末端风量调节控制法(TRAV).     

“北斗”救生终端海上自适应功率退避算法

受海况、浸水、结冰、对星等因素影响,飞行员海上遇险后报位可靠性较低,工作时长较短。为此,提出一种自适应功率退避方法,在对报位影响因素分析基础上,利用深度神经网络,通过对经纬度、高度、俯仰角、方向、加速度、速度、浸水、信号、电量等多维度数据进行学习,拟合出覆冰、浪涌、液面等信号特征与环境特征联想模型,自适应控制信号发射时机,实现功耗的有效控制。试验表明,该方法将通信成功率及工作时长分别由36.3%、6.0 h提升至73.3%、8.6 h。     

Key drivers of passengers' overall satisfaction at klia2 terminal

The purpose of this study is to examine the airport service quality dimensions based on the ASQ survey and investigate the best predictor for overall satisfaction. The context of this study is the klia2 terminal passengers, which are predominantly users of the low-cost carriers at Kuala Lumpur International Airport. Secondary data obtained from the airport operator on the 2016 ASQ survey for the klia2 terminal was analysed using the PLS-SEM method. The grouping and impact of the thirty-three service quality elements from the ASQ survey were tested against the overall satisfaction element. The findings indicated that twenty-two out of the thirty-three elements were valid measures for the klia2 terminal users which forms the eight dimensions i.e. access, airport environment, airport facilities, arrival services, check-in, finding your way, passport and security. Airport environment was found as the best predictor in determining passengers’ overall satisfaction at klia2 terminal and should be given particular focus by the airport operator for continuous improvements.     

航站楼火灾场景下的人员疏散仿真研究

机场航站楼结构复杂,发生火灾时极易对人员的生命财产安全造成威胁。为直观了解航站楼中不同位置发生火灾时产生的烟雾对人员疏散的影响,建立航站楼到达厅与夹层通道的火灾模型与人员疏散模型,分析3种不同火源情况下各关键位置烟气的温度、CO浓度和减光系数与疏散情况。结果表明,行李转盘区与夹层通道发生火灾时烟气会弥漫整个夹层通道,影响疏散安全。在航站楼现有建筑结构下,到达口联动开启可有效缩短人员疏散时间。     

Book Reviews

Rail privatisation was a controversial, widely unpopular policy whose implementation was not inevitable. This article employs counterfactual history methodology to examine whether the move to rail privatisation in Britain might have failed. It places the privatisation proposals in context by examining opposition within the Conservative Party and British Rail. The paper then focuses on three key counterfactual questions, including the significance of New Labour's reversal of its commitment to renationalise rail under its ‘third way’ policy and the possible consequences had the move to privatise rail failed. Based on the historical evidence available, it concludes that the move to rail privatisation could have failed, and that performance would have been better had rail remained an integrated, nationalised industry.
