This paper develops a practical miniature and portable vapor compression refrigerator. The dimensions of the refrigerator are 190mm×190mm×100mm and its weight is 2.75kg. It integrates a miniature variable speed rotary compressor with a miniature electronic expansion valve (EXV) operating in...

In this paper, a common rail diesel research engine was converted to operate in dual-fuel mode and extensive experiments were conducted to investigate the effects of natural gas injection timing on the combustion and emissions performance under different pilot injection pressure and timing at...

Purpose – The algorithm of disjoint literature‐based knowledge discovery provides a convenient, efficient and effective auxiliary method for scientific research. Based on an analysis of Swanson's A‐B‐C model of disjoint literature‐based knowledge discovery and Gordon's intermediate...

Green digital finance plays a crucial role in driving green production, consumption and facilitating the low-carbon transition of energy consumption structures. This paper delves into the impact of green digital finance on this transformation from a multidimensional perspective for the first...

We show that the recent results on the Fundamental Theorem of Asset Pricing and the super-hedging theorem in the context of model uncertainty can be extended to the case in which the options available for static hedging (hedging options) are quoted with bid-ask spreads. In this set-up, we need...
