Gas flows through micro shock tubes are widely used in many engineering applications such as micro engines, particle delivery devices etc. Recently, few studies have been carried out to explore the shock wave excursions through micro shock tubes at very low Reynolds number and at rarefied gas condition. But these studies assumed centered shock and expansion waves, which are generally produced b...
This document presents WINNER channel models. The channel models cover WINNER propagation scenarios for indoor, urban macro-cell and micro-cell, stationary feeder, suburban macro-cell, and rural macro-cell. Both geometric-based stochastic channel model and reduced-variability (clustered delay-line) models are presented. The channel models are mainly based on measurement data. Keyword list: Chan...
For neuroprosthetic use of afferent activity, model results and experimental recordings of action potentials (ap's) made with Tungsten micro electrodes in rat peronedsural nerve are presented and compared. The model shows that the normal shape can be as well biphasic as triphasic, depending on extraneural conductivity. In the experiments, five classes of ap shapes are observed, of which two are...
Abstract In this study, the optical diagnostics techniques of infrared (IR) absorption and chemiluminescence were applied to a racing engine. A small M5 IR sensor and Cassegrain optics sensors were developed to measure in-cylinder fuel concentrations and local chemiluminescence intensities. The small IR sensor was able to withstand racing engine operating conditions up to 16,000 rpm and exhibit...
A full-field hard X-ray imaging beamline (BL-4) was designed, developed, installed and commissioned recently at the Indus-2 synchrotron radiation source at RRCAT, Indore, India. The bending-magnet beamline is operated in monochromatic and white beam mode. A variety of imaging techniques are implemented such as high-resolution radiography, propagation- and analyzer-based phase contrast imaging, ...
A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...
