Purpose – The purpose of this paper is to investigate the statistical correlation properties of the Shanghai Interbank Offered Rate (SHIBOR) interbank lending market. Design/methodology/approach – The authors apply methods of correlation analysis, random matrix theory (RMT) and minimum...

Purpose: The purpose of this paper is to explore the research status and development trend of the field of event detection in social media (ED in SM) through a bibliometric analysis of academic publications. Design/methodology/approach: First, publication distributions are analyzed including...

The performance of a proton exchange membrane (PEM) fuel cell is greatly affected by the operating parameters. Appropriate operating parameters are necessary for PEM fuel cells to maintain stable performance. A three-dimensional multi-phase fuel cell model (FCM) is developed to predict the...

This paper presents an investigation concerning the effects of operating conditions on the performance of a passive direct methanol fuel cell (DMFC). A self-developed porous metal fiber sintered plate (PMFSP) is used as the methanol barrier between the fuel reservoir and current collector at the...

Fluid velocity distribution among microchannels plays important role on the reaction performances. In this work, the velocity distribution among microchannels with two different manifold structures is compared by a three-dimensional CFD model under two situations respectively, no reaction and...

To realize high-concentration operation of a passive air-breathing direct methanol fuel cell (PAB-DMFC) is a critical issue that should be addressed before it is used for practical applications. This work reports the feasibility of using a porous metal fiber sintered felt (PMFSF) as the anodic...

We investigate the problem of dynamic optimal capital growth of a portfolio. A general framework that one strives to maximize the expected logarithm utility of long term growth rate was developed. Exact optimization algorithms run into difficulties in this framework and this motivates the...

The impact of monetary policy changes on the monetary market and stock market in China is investigated in this study. The changes of two major monetary policies, the interest rate and required reserve ratio, are analyzed in a study period covering seven years on the interbank monetary market and...

The use of methanol vapor is helpful to reduce the effect of methanol crossover in a direct methanol fuel cell. This study develops a passive vapor-feed direct methanol fuel cell (VF-DMFC) based on a pervaporation membrane and sintered porous metals which act as functional layers for effective...
