Susceptibility is an important issue in debris flow analysis. In this paper, 26 large-scale debris flow catchments located in the Wudongde Dam site were investigated. Seven major factors, namely, loose material volume per square kilometer, loose material supply length ratio, average gradient of...

Through accident prediction models, researchers have identified correlation between crash risk and many different explanatory factors, such as traffic volume, roadway geometries, temporal effects, driver characteristics, and and use, but cannot give definite safety effects of countermeasures....

The study develops an integrated model to examine factors, particularly government factors, which influence IT adoption in Chinese firms. By analyzing the survey data from 1540 firms across 14 industries and across various ownerships in Shanghai, the study contributes several insights into...

This paper adopts the concept and mechanism of mathematical ecology theory, researches the revolutionary of automobile industry chain by setting up mutualism model of two species. Results of simulation show that automakers are more sensitive to the change of environmental resource. Automakers...

Previously, the authors have designed and implemented an active motion control “virtual crankshaft” for a free piston engine, which enables precise piston tracking of desired trajectories. With this mechanism, the volume of the combustion chamber can be regulated, and therefore the pressure,...

Increasing freshwater demands have made allocation of water in water-scarce regions especially severe in arid areas. To assist in allocating water, a virtual water assessment methodology is described to assess strategies of saving water by identifying products which would be better as imports...

In this paper, we propose an extension to the first-order branching process with immigration in the presence of fixed covariates and unobservable random effects. The extension permits the possibility that individuals from the second generation of the process may contribute to the total number of...

General Circulation Models (GCMs) are applied to Gansu Province, northwest China, to assess temporal and spatial trends of precipitation and temperature, and the trends compared to historical trends. The simulations for the three regions of the Province indicate that temperatures will increase...

This paper analyzes the feasibility of carrying out various pricing strategies in recreational fishery management. It also introduces the four common pricing means, which are time (season) differential pricing, customer differential pricing, quantity discount and two-part tariff system. The...
