The mechanism of hydrothermal liquefaction of cypress was investigated by examining the effects of temperature and retention time on the characteristics of the solid residues remaining after liquefaction. The solid residues were divided into acid-soluble and acid-insoluble residues. Results...

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...

This paper models and analyzes the throughput of a two-stage manufacturing system with multiple independent unreliable machines at each stage and one finite-sized buffer between the stages. The machines follow exponential operation, failure, and repair processes. Most of the literature uses...

Given China's notorious air pollution, particularly fine particulate matter (PM2.5) pollution, a detailed understanding of socio-economic costs of air pollution and potential impacts of its abatement policies is crucial for policy-making if sustainable development is to be realized. To provide...

Purpose – The purpose of this paper is to investigate the effects of network strength, transaction-specific investments and inter-personal trust on business relationship satisfaction for small-and-medium-sized enterprises (SMEs) involved in agri-food processing and exporting in China....

Financial bubble is an intensively discussed but quite controversial topic. In current literature, the researches usually focus on the (ir)rationality of traders and its impacts on the bubble. We thereby propose a completely different perspective, that is, of traders’ heterogeneity and its...

A correct or precise estimation of the Hurst exponent is one of the fundamentally important problems in the financial economics literature. There are three widely used tools to estimate the Hurst exponent, the canonical rescaled range (R/S), the variance rescaled statistic (V/S) and the Modified...

Although there are many reports on the empirical evidence of the existence of multifractality in various financial or commodity markets in current literature, few can be found to compare the multifractal properties of emerging and developed economies, especially for agricultural futures markets...

In this paper, based on the detrended fluctuation analysis (DFA) method and the detrended cross-correlation analysis (DCCA) method, we propose an improved method of minimum-variance (MV) hedge ratio, i.e., the detrended minimum-variance (D-MV) hedge ratio, which can measure the hedge ratio at...

Based on time series of crude oil prices (daily spot), this paper analyses price fluctuation with two significant parameters [tau] (speculators' time scales of investment) and [epsilon] (speculators' expectations of return) by using Zipf analysis technique, specifically, by mapping [tau]-returns...
