In this paper, we apply car-following model to study the influences of the vehicle’s fuel consumption and exhaust emissions on each commuter’s trip cost allowing late arrival. Our results show that considering each commuter’s fuel cost and emission cost only enhances his trip cost and the...

Based on the linear relationship between solar radiation and sunshine duration, the Angstrom model is widely used to estimate solar radiation from routinely observed meteorological variables for energy exploitation. However, the relationship may have changed in quickly developing regions in the...

The technology of in situ immobilization with amendments is an important measure that remediates the soil contaminated by heavy metal, and selecting economical and effective modifier is the key. The effects and mechanism of steel slag, the silicon-rich alkaline by-product which can remediate...

The strong flux variations distributed on the surfaces of receiver during its service life can intensify material aging and thus deteriorate the thermal performance of material. Generally, the single focal point heliostat field, i.e., focusing at the centre of the aperture of a cavity receiver,...

DAHAN, the pioneer 1MWe CRS (Central Receiver System) project, is now under construction at the foot of the Great Wall of Badaling in Beijing. The coupled system-collector and solar central receiver, which plays a dominant role in the radiation-heat conversion, is the most important component in...

1 MW Dahan solar thermal power tower plant is modeled from mathematical models for all of the working conditions using the modular modeling method. The dynamic and static characteristics of the power plant are analyzed based on these models. Response curves of the system state parameters are...

A step-change flow rate liquid hot water (SCFLHW) process was developed with the objective of improving the total sugars recovery including xylose and glucose from sweet sorghum bagasse (SSB). Total xylose yield increased from 60% for batch system (4.25% w/v, 18 min, 184 °C) to about...

The relationships between fire danger indices and fire risk have been extensively studied in many regions of the world. This work uses partial effect analysis in semiparametric logistic regression models to assess the nonlinear relationships among location, day, altitude, fire danger indices,...

In the North China Plain (NCP), while irrigation using groundwater has maintained a high-level crop productivity of the wheat-maize double cropping systems, it has resulted in rapid depletion of groundwater table. For more efficient and sustainable utilization of the limited water resources,...
