In this paper, we report on an underground water-source water-loop heat-pump (UWSWLHP) air-conditioning system for a tall apartment building in Beijing. Water at 14 °C was used as an external low-temperature heat-source. By analyzing field-test data for two years, the authors assessed the...

We study the 52-week high momentum strategy in international stock markets proposed by George and Hwang [George, T., Hwang, C.Y., 2004. The 52-week high and momentum investing. Journal of Finance 59, 2145-2176.]. This strategy produces profits in 18 of the 20 markets studied, and the profits are...

We investigate whether there is a U-shaped relationship between GDP per capita and country patent protection for pharmaceuticals. Using the Pharmaceutical Intellectual Property Protection (PIPP) Index, we find no evidence of a U-shaped relationship for any of the 154 countries in our sample or...

The purpose of our research in China is to develop a small-scale solar PV system with the features of higher conversion efficiency, higher reliability, reasonable price and ease of operation, which is composed of a PV panel, battery, controller, inverter, etc. The main research work includes the...

Designing a cost-effective phase change thermal storage system involves two challenging aspects: one is to select a suitable storage material and the other is to increase the heat transfer between the storage material and the heat transfer fluid as the performance of the system is limited by the...

This work studies a variant of the online generalized assignment problem, where there are m⩾2 heterogeneous servers to process n requests which arrive one by one over time. Each request must either be assigned to one of the servers or be rejected upon its arrival, before knowing any...

This paper presents a system to upgrade faecal matter in an environmentally friendly way by the deployment of plasma gasification and SOFC (solid oxide fuel cells). The entire system chain, including a dryer, a microwave-assisted plasma gasifier, a gas processing system and an SOFC system, is...
