(2009) is used to study adsorptive solute of Cr (VI) loss from soil into surface runoff with nonlinear Temkin adsorption. Laboratory experimental data are used to verify the model with nonlinear Temkin isotherm adsorption equation. Study results suggest that model simulations with Temkin isotherm equation agree well with the observed data, which means that the model is valid. The sensitivity of the model parameters were analyzed, which shows that the mixing parameters γ and α are more sensitive to the soil solute of Cr (VI) loss to surface runoff while the parameter B1 and A1 of adsorption equation is less sensitive. The solute of Cr (VI) loss to surface runoff is decreasing with increasing θ0, while soil bulk density is vice verse.

This research has developed the active noise cancelation (ANC) equipment for reducing road traffic noise. This ANC equipment is consisted of microphones, controllers and speakers. This research has conducted simulation by using the noise source that was recorded at the roads to confirm the ANC equipment. The simulation conducted in the field used 1 non-directional speaker and 2-directional speakers. Also, this simulation applied the Fx LMS algorithm. The result of this study showed that the non-directional speaker was shown to reduce the maximum of 5.5 dB (A) in low frequency band. And, the 2 directional speakers was shown to reduce the noise for 2.5 dB (A) and 3.8 dB (A), respectively. This equipment did not diffuse anyexternal influence and operated stably.
Correlation Degree Model of Urban Signalized Intersection Group Based on Turning Flows
Authors: Zhang Qian , Guo Xiu Cheng , Liang Hao
Published: September 2014

This article analyzes the limitations of calculating correlation degree based on road sections and built correlation model based on the turning flow of the intersection. In addition to the traditional contributing factors, the model considers two other key factors——turning proportion of intersections and signal phase. Therefore, the proposed model can reflect the spatial and temporal heterogeneity between each turning flows on a road section. A case study to four actual intersections is conducted to test the effectiveness of this model. The results show that the proposed correlation model can better descript the relationship of adjunct intersections and find the critical route for signal coordination.
