A force-driving cellular automata model considering the social force on cell movement, such as the desirous willing of a pedestrian to exit, the repulsive interaction among pedestrians or between pedestrians and obstacles, was set up to investigate the evacuation behaviors of pedestrians at a...

The breakage of the glass to metal sealing is the primary ongoing issue for the solar receiver tubes in parabolic trough solar power systems. Sealing failure leads to loss of the vacuum inside the tube which substantially reduces the collector efficiency. It is a technical difficulty to obtain...

A preliminary method for determining acceptable trace element levels in coal was established. In addition to the conventional coal quality parameters ash and sulfur, potentially hazardous trace elements As, Be, Cd, Cl, Cr, F, Hg, Mn, Ni, Pb and Se were selected for the evaluation, and their...

Saving rates and household investment in stocks and business equity are all increasing in income and wealth. Introducing subsistence consumption to a common-across-households Epstein-Zin-Weil utility function is up to a quantitative explanation, in the context of stan- dardized parsimonious...

Surface cover degree, monthly variation of topsoil water content, loss of soil and nutrient in alfalfa-corn intercropping, strip rotation cropping and corn monoculture were studied in this paper. Then soil and water conservation effect of these planting modes were compared. Results showed that...

Oil-impregnated paper is widely used in power transmission equipment as a reliable insulation. However, copper sulphide deposition on oil-paper insulation can lead to insulation failures in power transformers. This paper presents the influences of copper sulfur corrosion and copper sulphide...

Converter transformers are the key and the most important components in high voltage direct current (HVDC) power transmission systems. Statistics show that the failure rate of HVDC converter transformers is approximately twice of that of transformers in AC power systems. This paper presents an...

It has been hard to model a crowd evacuation process considering different walking abilities using a synchronous cellular automaton. That is because the cross and the overlaps of routes have to be taken into consideration and the conflicts resolution between pedestrians is more complex. However,...

People prefer to walk on the right-hand side of the road for physical and social reasons. In this paper, pedestrian counter-flow in a channel is simulated with the Cellular Automata (CA) Model, with focus on right-preference. Two types of pedestrians are taken into account, walking leftward and...

This paper provides further evidence on the role of the efficient market hypothesis and the rational asset pricing model in the explanation of Chinese closed-end fund discounts. The closed-end fund discount presents a potential anomaly to the efficient market hypothesis. The results of the...
