This study presents a joint analysis of daytime and nighttime crash frequencies at the zone level with consideration spatial correlations. Crash data from 131 traffic zones in Hong Kong 2011 are investigated. A Bayesian bivariate conditional autoregressive model is proposed to establish links between attributes, road network characteristics, land use patterns. The allows not only for distinct heterogeneous effects each dependent variable, but also correlations them.The parameter estimates...
The new controllable line-commutated converter (CLCC) with trip capability not only retains the large capacity and low cost of conventional LCC in topology control strategy, but also withstands phase change failure under various AC faults. To verify operational performance reliability DC transmission system based on CLCC converter, a CLCC-HVDC simulation model is developed within PSCAD/EMTDC. transient HVDC compared same model. results show that, LCC-HVDC, has good suppression phase-change...
In this paper, the authors propose a highly conductive die attach material based on Ag@Sn powder for power devices operating at high temperatures or in other harsh environments. The preform can be reflowed 250 °C (18 above T m of Sn, 232 °C), but resulting bondline sustain up to 400 with shear strength due re‐melting temperature formed Ag 3 Sn ( = 480 °C) after complete consumption outer layers. addition, exhibits excellent electrical and thermal conductivities embedded particles...
Due to the low cost, high critical current density ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">J</i> <sub xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> ), anisotropy and a temperature of about 40 K, MgB xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> tapes/wires is promising operate in High-temperature Superconducting Magnetic Energy Storage (SMES).

The aromatic structure of three different-rank vitrinites, V-YJL (Ro =0.61%), V-AW =1.13%), and V-JC =2.22%), was investigated by X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM), atomic force (AFM). Based on the HRTEM experimental results, it found that with vitrinite reflectance increasing, distributions layers changed from disordered to well-aligned. shapes twisted more straight parallel. In addition, there were large-sized in samples larger reflectance....
In the present work, titanium carbide–titanium boride coatings are prepared on Ti6Al4V by powder immersion reaction assisted coating (PIRAC). Microstructure and phase composition of gained surface layers characterised X-ray diffraction scanning electron microscopy equipped with energy dispersive spectrometer. Results show that homogeneous can be formed substrate. Phases co-existed TiC, TiB 2 their content varies PIRAC treatments. Hardness borides at 900°C is about 24·5 GPa, while 1000°C 22·5...
NbTi superconducting Wire has the advantage of excellent processing characteristics, stable properties and low cost. It been widely used for magnetic fields <9 T. To increase stability reduce cost magnets, it is necessary to improve Critical Current Density at high (≥9 T) wire. Therefore, this research focuses on procedure obtain samples with higher Jc (4.2 K, 9 738 A/mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

NbTi strands are widely used in magnetic resonance imaging (MRI) and other superconducting magnets for their good processing characteristics, low cost, performance. With the huge demand high yield strength monolith wire MRI using less liquid helium, improving of becomes a problem that urgently needs to be solved. In this study, we adopted new fabrication process by "enameling insulation before rolling forming" improve wire. By choosing suitable material adjusting working rate, property has...
