    使用无线传感器网络的智能交通灯路口管理外文翻译资料

    英语原文共 11 页, 使用无线传感器网络的智能交通灯路口管理 MARIO COLLOTTA, TULLIO GIUFFRE, GIOVANNI PAU, GIANFRANCO SCATA Kore University of Enna Faculty of Engineering and Architecture Cittadella Universitaria, 94100 Enna ITALY (mario.collotta, tullio.giuffre, giovanni.pau, gianfranco.scata}@unikore.it 摘要:近年来,无线传感器网络(WSN)越来越多地参与智能交通系统(ITS)优化,尤其是信号交叉口的动态管理。本文讨论了现有技术,并展示了一种IEEE 802.15.4网络体系结构,用于监视交通信号灯附近的车辆交通流。该体系结构的特征在于创新的算法,可根据交通流的测量值确定交通信号灯的绿灯时间和相序。这项工作的主要目的是减少平均等待时间。为了确认所提出方法的有效性,已经考虑了一些案例研究,并进行了一些模拟。 关键词:无线传感器网络,交通

    用于超快且稳定的锂/钠离子电池的伪电容主导的MoS2-in-Ti3C2上层结构的二维纳米空间受限合成外文翻译资料

    英语原文共 9 页, 附录 A 外文文献(译文) 用于超快且稳定的锂/钠离子电池的伪电容主导的MoS2-in-Ti3C2上层结构的二维纳米空间受限合成 摘 要 探索实现二维纳米材料尺寸和层数精确控制的通用策略,对于实现超快速且稳定的锂/钠离子电池来说是一个巨大的挑战。本文报道了借助静电吸引和随后的十六烷基三甲基溴化铵(CTAB)定向生长,将1-3层MoS2纳米晶体合成至2D Ti3C2中间层纳米空间。MoS2纳米晶体通过2D约束效应和强大的Mo-C共价键牢固地固定在中间层中。 令人印象深刻的是,在实验中首次成功观察到嵌入MoS2还原峰中的Li 的消失,表现出典型的表面控制电荷存储行为。赝电容为主的贡献可确保更快,更稳定的Li / Na存储性能。 如预测的那样,该电极即使在20 A g-1的条件下也表现出340 mAh g-1的很高的Li 存储容量,并且循环

    英语原文共 6 页, 钾镁对不同类型茶品质成分的影响 阮建云,1吴旭1 和 Rolf Hardter2* 1中国农业科学院茶叶研究所,杭州310008 2国际钾盐滴定仪,德国卡利德·萨尔茨有限责任公司,邮政信箱10 20 29,D -34111卡塞尔,德国 摘要:在长期实验中,研究了钾和镁营养对红茶,乌龙茶和绿茶等不同类型茶品质成分的影响。结果表明,钾和镁肥料的施用增加了各种茶类型的游离氨基酸和咖啡因的含量,其中包括过程中这两种营养素的的最大增加量。钾肥的施用也增加了茶叶中多酚的含量。镁对茶多酚含量的影响不一致。通常,镁明显降低茶了多酚的含量,只有在土壤中缺乏植物有效钾和镁的情况下,镁含量才会略有增加。钾肥还增加了茶 红素和茶红素的含量,它们是酿造红茶的重要品质成分。施用钾和镁可大大改善乌龙茶的风味。

    机械设计外文翻译资料

    英语原文共 10 页, Mechanical Design John Ernst Abstract:A machine is a combination of mechanisms and other components which transforms transmits. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines. The term 'mechanical design' is used in a broader sense than 'machine design' to include their design. The motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers. Keywords: Mechanical Design; Mechanisms Design Process;Application 1. The Design Progress Designing starts with a need real. Existing apparatus m

    附录B 外文原文 Goodwill, Profitability, and the Market Value of the Firm Abstract Despite the importance of goodwill to the survival of many businesses, and to the easy working of most, the concept has been the focus of little theoretical and empirical research in accounting or financial economics. This paper identifies a number of firm-specific characteristics with a consistent influence on goodwill, and a consistently positive influence of accounting goodwill numbers on both profitability and the market value of the firm in the nonmanufacturing firm. As such, current accounting goodwill measures offer a useful perspective on the firmrsquo;s intangible capital. Introduction Accounting for goodwill and other intangible assets is a subject of growing academic and public policy interest. From an academic perspective, accountants and financial economists seem increasingly concerned with finding better means for the recognition and valuation of intangibl

    澳大利亚房地产投资信托的利率风险:面板分析外文翻译资料

    附录B 外文原文 INTEREST RATE RISK OF AUSTRALIAN REITS: A PANEL ANALYSIS ABSTRACT Management structures of many Australian REITs have shifted towards internal property management since 2001. Sector returns have been rewarding until the Global Financial Crisis, but rising costs of debt and years of aggressive borrowing have eroded REIT values. Externally managed trusts had relatively higher levels of debt than internally managed counterparts thus increasing the sensitivities to interest rate risks. Yet internally managed REITs engage in a wider set of operating activities which compound market and financial risks. This study uses panel and panel quantile regressions to examine the joint impact of financial leverage and management structure on REIT returns in terms of their sensitivities towards the stock market and changes to interest rates from 1980 to 2013, and how these vary at different parts of an economic cycle. We find that the impact of market returns is grea

    Whats in the parcel locker?Exploring customer value in e-commerce last mile delivery Yulia Vakulenko⁎, Daniel Hellstrouml;m, Klas Hjort LTH, Lund University, Sweden ABSTRACT This study explores customer value in relation to parcel lockers, a self-service tool that reshapes the delivery and returns experience in the context of e-commerce last mile delivery. Parcel lockers offer a response to retail and last mile delivery challenges provoked by the rapid growth of e-commerce worldwide. Retailers, logistics service providers, communities, and other stakeholders now face issues due to increased volumes of goods sold online. The introduction of parcel lockers to service algorithms is intended to address these issues by involving consumers in the service process. However, the existing research fails to provide knowledge about the customers view on this new technological solution. This study followed a focus group design and built on grounded theory to provide insights i

    附录B 外文原文 Bank Risk Management: A Regulatory Perspective Abstract The globalization of financial markets, information technology development, and increasing competition have largely affected bank business and its risk management. Together with these forces, regulatory factors play a significant role. This chapter approaches bank risk management under the regulatorsrsquo; perspective with an emphasis on the risk-based capital regulation. Specifically, how bank risk is regulated under the risk-based capital regulation and whether the regulation shapes bank risk are discussed in detail. In such a way, the chapter provides better understanding of the risk-based capital regulation and bank risk-taking behaviors. Key words: Basel Accords, capital regulation, bank risk, risk management, credit risk 1.Introduction Risk management is important for a bank to ensure its profitability and soundness. It is also a concern of regulators to maintain the safety and
