In this paper, we choose six representative futures contracts—soybean, soy meal, corn, hard wheat, strong gluten wheat, and sugar—from China's futures markets to examine predictability and market efficiency from the perspective of the price-volume relationships. Our empirical results show...

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...
