chemical methods ( actinometry ) depend on the measurement of the extent to which a chemical reaction occurs under the influence of uv light. two chemical actinometers have been used in this research. in one method, the mixtures of potassium peroxidisuiphate butanol solutions were irradiated for various time intervals, and ph-changes were determined. a linear relationship was observed between t...
Aeroelastic dynamics must be accurately known to ensure safe and efficient flight testing. Unfortunately, most models of aircraft systems typically describe only the linear dynamics. These models are inadequate for predicting behaviors, such as limit cycle oscillations, resulting from nonlinearities. This paper presents an approach to augment a linear model by identifying associated nonlinear o...
In order to improve the measurement accuracy of the linear CCD in the intersection of vertical target measurement system, the calibration model of linear CCD’s internal parameters is established and the various factors that affect the accuracy in the calibration process are analyzed. Making use of the linear CCD imaging optical principle, the optical center and the effective focal length are ca...
