R744 is the most competitive, and R744 is the most ideal when flammability and toxicity are strictly limited. There are some problems in the current R744 heating system, for example the pressure at the heat release side is often more than 10.0MPa. High operating pressure brings high cost....

The presence of silicon oxyphosphide in the heavily phosphorus-doped n + -type polycrystalline silicon film (poly Si) of TOPCon solar cell has been mainly revealed through a depth-profile X-ray photoelectron spectroscopy (XPS) characterization of chemical components. X-ray diffraction (XRD)...

Direct synthesis of valuable aromatics, such as xylene from CO2 hydrogenation is of highly interest for carbon emission reduction and reutilization, but it remains a challenge due to the poor product yield limited by low CO2 conversion. On the other hand, toluene methylation with methanol...

The influence of discharge price on user willingness to participate in the vehicle-to-grid (V2G) market is explored in this paper by constructing critical discharge electricity price (CDEP) and user participation willingness (PW) models. Based on the CDEP model, 12 typical EV models are measured...

Hydrocarbon-fueled scramjet is one of the most promising air-breathing propulsion systems for hypersonic flight, but the wall thermal protection issue strictly limits its maximum flight Mach number. This study presents a fuel indirect cooling based thermal management system (TMS) scheme, in...

The rise of environmental awareness changes consumers’ behavior. European Commission stated that 75% of Europeans are “ready to buy environmentally friendly products even if they cost a little bit more” (Brécard, 2014). With the growth of consumer’s willingness to pay(WTP), the...

Capital gains tax significantly affects investors' optimal investment policies. Inflation varies stochastically and can become elevated for a long period of time. However, the impact of inflation on tax timing and consumption is largely ignored in the existing literature. We develop an optimal...

In this report, we discuss our recent analysis of incorporating higher moments in factor models. We have used a simplified data set and assumptions to conduct an initial feasibility study in this area. Our expectation is that this initial work, if sufficiently promising, can be extended with...
