Figure 2 Schematic of a double-section laser design and the experimental setup for SLQD absorption measurements.
(a) Schematic of a double-section laser design with amplifying and absorbing sections, used to measure the electroluminescence, and absorption spectra for two light polarization directions: in the plane perpendicular to the growth axis (x y plane) and along the growth direction (z axis) of the structure.
A railway bridge with a double composite section has been proposed to enhance the structural performance of existing twin-girder bridges, because the governing design parameter of railway bridges is flexural stiffness.
Some of them have variable width (either simply-supported decks or continuous ones up to three spans), whereas other bridges are of variable depth, so they can reach 59 m for a double track section and 75 m for single track.
Comprising 52 musicians, it is versatile across many musical forms, and is equipped with a "double rhythm section" - one for pop and rock, and one for jazz based music.
In device, the main unit is the hydrocyclone with a double cone section, and the tangential double-inlet was designed to stabilize the flow field (shown as in Fig. 3) [25].
Tests on a double-track section of the Mälaren line in Sweden demonstrates a significant potential for energy saving.
After the San Francisco earthquake collapsed a double-deck section of the Nimitz Freeway, killing 42 people, engineers retracted the predictions, saying they had no "specific knowledge" that 100 deaths could occur.
The year there were the most double sections was 1988, when two concurrent sessions each of the Bacteriology, Immunology, and Virology sections were held.
Experimental investigations have been carried out, for a low Reynolds number case, over a flat plate installed within a double contoured test section designed to produce an adverse pressure gradient typical of Ultra-High-Lift turbine blade profiles.
The system consists of a main beam with a double rectangular cross section, into which are fitted two struts that are connected to steel cables anchored to transverse steel dowels embedded at the ends of the main beam.
