A method for semi-continuous (10 min time resolution) PM2.5 nitrate and sulfate measurements, based on the humidified impaction with flash volatilization design of Stolzenburg and Hering (Environ. Sci. Technol. 34 (2000) 907), was evaluated during the Pitt ...
Motion capture techniques are rarely based on orientation measurements for two main reasons: (1) optical motion capture systems are designed for tracking object position rather than their orientation (which can be deduced from several trackers), (2) known ...
This is a presentation of the techniques used to process inertial and GPS data collected during an airborne gravimetric and altimetric survey in order to obtain absolute position and attitude estimates of the sensors mounted on board the aircraft. For high ...
A combined measurement of O3 concn. and wind speed by lidar is presented, which permits a flux detn. of this pollutant. Measurements were obtained using a shot per shot differential absorption lidar (DIAL) system in which each return is recorded, stored, a ...
Different measurement techniques have been used to detect cavitation on a Francis turbine model. The results are compared to those obtained on the prototype and presented in the first of this series of articles. The runner mode! used for that study is buil ...
One of the most important parameters in characterization of integrated optical devices is precise determination of the effective cut-off wavelength of the fundamental and first-order modes, since this sets the exact region of single-mode operation. This pa ...
The use of dielec. measurements to assign mol. configurations was examd. with model compds. of the chloroalkane, chloroalkene and chlorocumulene type. A dielec. microcell is described which allowed measurements of 0.35 mL samples under exclusion of air. Bo ...
In a recent paper, we measured the hole diffusion length in a single quantum well (SQW) by a novel method using SEM-cathodoluminescence, assuming that the carriers diffuse only in the SQW. This assumption needs to be checked. Therefore, we present here a m ...
The purpose of this work is to predict the behaviour of electric devices using superconducting tapes, including the transition of those tapes to the normal state, which implies a typical non linear behaviour. The frequency domain studied is as wide as poss ...
One of the most important parameters in the characterization of integrated optical waveguides is the precise determination of the effective cut-off wavelength of the fundamental and the first order mode, since it sets the exact region of single-mode operat ...
