The thermal conductivity of boron nitride/ethylene glycol (BN/EG) nanofluids was investigated by transient hot-wire method and two abnormal phenomena was reported. One is the abnormal higher thermal conductivity enhancement for BN/EG nanofluids at very low-volume fraction of particles, and the other is the thermal conductivity enhancement of BN/EG nanofluids synthesized with large BN nanopartic...
Abstract Road detection on aerial and remote sensing vague images is a hard task. In this paper, an automatic road method for the proposed. The firstly uses improved MSR algorithm to enhance image, it automatically takes different scales in image regions, based depths obtained by dark channel prior algorithm. Then enhanced roughly segmented principle of local gray scale consistency, that, eight...
This study tested the effects of lane width, lane position and edge shoulder width on driving behavior for a three-lane underground urban expressway. A driving simulator was used with 24 volunteer test subjects. Five lane widths (2.85, 3.00, 3.25, 3.50, and 3.75 m) and three shoulder widths (0.50, 0.75, and 1.00 m) were studied. Driving speed, lane deviation and subjective perception of driving...
Objective: In the present study we investigated the role of hematological parameters, including neutrophil/lymphocyte ratio and platelet/lymphocyte ratio, mean platelet volume and platelet distribution width in the evaluation of treatment efficacy in adult patients diagnosed with cutaneous leishmaniasis. Methods: The study group included 45 adult patients diagnosed with cutaneous leishmaniasis ...
We present computer modeling for effects of the p/i interface upon the open-circuit voltage VOC in amorphous silicon based pin solar cells. We show that the modeling is consistent with measurements on the intensitydependence for the interface effect, and we present an interpretation for the modeling based on thermionic emission of electrons over the electrostatic barrier at the p/i interface. W...
Epitaxial GaN films were grown by metal organic chemical vapor deposition (MOCVD) on functionalized epitaxial graphene (EG) using a thin ( 11 nm) conformal AlN nucleation layer. Raman measurements show a graphene 2D peak at 2719 cm 1 after GaN growth. X-ray diffraction analysis reveals [0001]-oriented hexagonal GaN with (0002) peak rocking curve full width at the half maximum (FWHM) of 544 arcs...
