In this study authors focus on traffic dynamics and its impact on the pollutants dispersion in two street canyons forming an intersection equipped with traffic lights. A model based on Eulerian - Lagrangian approach to moving objects has been developed and integrated into a commercial CFD code StarCD. Inclusion of traffic dynamic leads to a better description of dispersion processes of pollutants in an intersection, where peak values of pollutant concentrations are often located. Informations about traffic situation were obtained from in-situ measurement. Results of CFD predictions of NOx concentrations are compared with measurements acquired from an automatic monitoring station located in the intersection.

The sintering characteristics, phase composition, microstructure and optical properties of 1:1 ZnAl2O4 spinel doped with Ti4+ from 1.125 to 4.5 mole-% synthesized through coprecipitation were investigated in this study. Effective densification was achieved at a low sintering temperature, 1350 °C after 1 h. Powder XRD patterns revealed that, besides ZnAl2O4 spinel and rutile as major crystalline phases, minor Zn2Ti3O8 phase was present in the sintered system, with its extent depending on the TiO2 content and sintering temperature. SEM micrographs demonstrated a coherent and uniformly distributed fine-grained microstructure in the fracture surfaces of the sintered Ti4+ doped ZnAl2O4 spinel ceramics body. The Tauc plot of Ti4+ doped ZnAl2O4 spinel exhibited a leftward shift of the band gap from 3.79 to 3.48 eV with increase of Ti4+ content from 0 to 4.5 mole-%. Ti4+ was observed to function as a normal grain growth accelerator during ZnAl2O4 sintering. This was probably due to enhanced grain boundary diffusion.

In this paper, we propose an X-architecture routing algorithm for a clock network. With the definition of 16-pattern X-routing for a pair of points, our algorithm applies these patterns to simplify the selection of merging segments whereas using the DME approach and constructs an X-clock tree with zero skew. An X-flip is employed to shorten the wire length of each pair of points as possible for minimal clock delay. Moreover, a wire sizing is applied to remove snaking wires for saving routing resource. Experimental results on benchmarks compared with other X-routing algorithms show that our improvements in terms of clock delay, wire length, power consumption, and via cost are 16%, 0.8%, 1.5%, and 17.4%, respectively.
