基于热释电红外传感的智能交通系统研究

介绍了一种基于热释电红外检测的智能红绿灯设计方案。该方案是在模糊算法的支持下,可根据交叉路口不同方向上动态的车流数量,确定红绿灯的时长分配,以替代传统的固定配时,从而最大限度地提高道路的通畅度。     

Z28 80A型滚丝机液压系统的改造

Ｚ２８ ８０Ａ型滚丝机的液压系统采用节流调速方式，系统功率损失大，传动速度不稳定；采用容积节流调速方式，并在系统中加装压力补偿器，则系统速度稳定性好，且有明显的节能效果     

Convertible bond issuance volume,capital structure,and firm value

We investigate whether convertible bond (CB) issuance volume that causes capital structure change would affect firm value. We focus on either the hand-collected data due to multiple CB issues or diverse CB issuance volume (CB-IV) measures, including CB-IV over debt, equity, and assets. We reveal that the firms with higher CB-IV would enhance firm value, somewhat different from previous findings that CB might not be a cheap financing instrument for raising funds. We infer that because increased CB-IV might not be easily permitted by Taiwan authorities, enterprises might endeavor to exploit profits by using the funds raised by CBs. We argue that, to our understanding, our explored issues are essential for enterprises because they link CB-IV and firm value through the capital structure channel. Given that these issues have rarely been a comprehensive focus, this study may contribute to the existing literature.     

When bigger is better: Investment volume drivers in infrastructure public-private partnership projects

This research studies the factors that favour the establishment of high-investment infrastructure public-private partnership (PPP) projects. We analyse 9121 PPPs, hosted in 107 developing countries, in the period 1997–2017. We find that PPP projects adopting contractual forms in which the private party takes more risks, awarded through competitive methods and benefitting from indirect government support programmes, are characterized by a larger investment volume. A more business-friendly economy and robust institutions configure the most conducive environment to establish larger investment PPPs. Furthermore, multilateral development banks’ support of the projects relates positively to their investment volume.     

基于SEEA2012的矿泉水资产清查价格研究

论文在SEEA2012总体框架的基础上,收集全国主要矿泉水资源的相关信息,对全国矿泉水探矿权和采矿权的数量、分布、权属、矿泉水类型、已探明的B级及以上允许开采量等情况进行摸底,通过对区内矿泉水资源量、企业生产成本、资源税费和矿泉水产品价格等相关信息的收集分析,在此基础上对相关参数进行清查价格体系研究,研究提出矿泉水资产清查价格建议。     

Return–volume nexus in financial markets: A survey of research

This paper provides a systematic review of the return–volume literature, broadly defined to include theoretical and empirical research relating to the intramarket and cross-market interlinkages between security return and trading volume characteristics in four financial markets, namely, the stock, bond, foreign exchange, and futures markets. Viewed through this lens, this paper attempts to review previous empirical research within a unified theoretical framework that relates the interlinkages between return and volume characteristics in various financial markets. Overall, this paper marks several interesting areas of debate and controversy based on several controversial theories and empirical findings in the literature, suggesting directions for future research.
