A multi-pulse injection strategy for premixed charge compression ignition (PCCI) combustion was investigated in a four-valve, direct-injection diesel engine by a computational fluid dynamics (CFD) simulation using KIVA-3V code coupled with detailed chemistry. The effects of fuel splitting...

High-performance TiO2–polythiophene hybrid solar cells are reported. Metal-free organic dye (D102) is employed to modify the TiO2/polythiophene interface. Results indicate that interfacial engineering and dye engineering are crucial for device performance.

Purpose This paper aims to investigate whether idiosyncratic volatility is priced in returns of equity funds while controlling for fund size and return momentum. Design/methodology/approach Following Fama and French (1993), an idiosyncratic volatility mimicking factor and a fund-size factor are...

Purpose – This paper aims to examine whether idiosyncratic volatility and other asset pricing factors predict growth rates of the ten Australian economic indicators. Design/methodology/approach – The authors use the Liew and Vassalou (2000) model augmented with an idiosyncratic volatility...

In this paper, a novel genetic algorithm — dynamic ring-like agent genetic algorithm (RAGA) is proposed for solving global numerical optimization problem. The RAGA combines the ring-like agent structure and dynamic neighboring genetic operators together to get better optimization capability....

An M/G/1 retrial queueing system with disasters and unreliable server is investigated in this paper. Primary customers arrive in the system according to a Poisson process, and they receive service immediately if the server is available upon their arrivals. Otherwise, they will enter a retrial...
