We empirically examine the effectiveness of referral marketing and price promotion in generating sales in a large e-commerce platform. Our results show that although referral marketing increases sales, its effect is attenuated by price promotion. We argue that price promotion arouses quality...

Online communities provide a social sphere for people to share information and knowledge. While information sharing is becoming a ubiquitous online phenomenon, how to ensure information quality or induce quality content, however, remains a challenge due to the anonymity of commentators. This...

Liquid fuel cells operated at room-temperature are promising candidates for the next-generation of power sources for microelectronic devices. Enabling high-concentrated or even neat fuel operation of fuel cells, which is currently limited by adverse fuel crossover through membrane, could...

Numerical simulations were carried out to investigate the performance of shape-stabilized phase change material (SSPCM) wallboard with sinusoidal heat flux waves on the outer surface and compared with traditional building materials - brick, foam concrete and expanded polystyrene (EPS)....

The interconnection between a renewable power generation facility and a power grid poses challenges because of volatility and intermittent characteristics. Energy storage is one of the best solutions for this problem. This paper presents an integrated energy storage system (ESS) based on...

An experimental research was conducted to investigate the heat transfer characteristics of steam condensation on horizontal twisted elliptical tubes (TETs) with different structural parameters. Experiments were carried out at the steam saturation temperature of around 100.5°C with the wall...

The wheels are one of the most worn components on a train. When the wear is unacceptable, the re-profiling can restore the shape of the wheel flange with the cost of decreasing the wheel diameter. The decision of re-profiling has serious implications for the life span of wheels. In this paper,...
