Results of an experimental study of the aerodynamics and spray density distribution of a liquid dispersed by an airstream atomizer inside a drying chamber. Velocity components of the drying agent and their radial distributions as a function of the distance from the spray plane are determined. Relationships for the distribution of dispersed liquid inside the drying chamber are derived. Interactions between the drying agent and the product in the drying chamber are analyzed. 相似文献

A comparative evaluation of the most commonly used linear methods for edge detection in grayscale images are presented. Detectors based on the first and second derivatives of image brightness are considered. The method for automatic edge tracking in grayscale images is proposed. The model for assessing errors and artifacts caused by sampling during digitization of real input images is proposed. Investigation of edge detectors isotropy and errors caused by input images sampling is conducted. The advantage of the Isotropic operator for edge tracking is shown. The noise immunity of linear edge detection methods is assessed and the superiority of 3 × 3 gradient operators for noisy images is shown. Isotropic and Sobel operators are identified to be optimal on a basis of sampling errors, output noise level, and computational complexity. 相似文献

A semianalytical model of a field-effect ballistic nanotransistor with a nanowire-based or nano- tube-based channel, which is applicable to describe transistors with various gate configurations, is proposed. Based on this model, the calculations of the distribution of the potential and electron concentration in a transistor channel are determined and its current-voltage characteristics are plotted. Considerable distinctions regarding the computation of short-channel transistors based on the local model and good agreement with the computations performed according to the rigorous models are revealed. 相似文献

The development of BN-1200 is based on the greatest possible use of tested and scientifically validated and developed technical solutions implemented in BN-350, -600, and the BN-800 design as well as new technical solutions that increase facility cost-effectiveness and safety. The BN-1200 design must permit the reactor to operate with different cores, including with denser fuel. The main fuel variant considered is oxide fuel and for the nearest term nitride fuel, for which the production technology involves the same steps as the oxide technology. The main approaches for choosing the parameters of the BN-1200 core as well as the results of computational studies are presented. 相似文献

This work presents a comparative estimate of white-noise insensitivity of the most requested linear edge detection techniques
dealing with grayscale images. We consider detectors based on the first and second derivatives of the image brightness. The
comparative evaluation was based on statistical analysis. The Kirsh and Frei-Chen operators were found to be less sensitive
to noise. 相似文献

A theoretical approach to solving the sintering problem of nuclear oxide fuels is described. We are proposing a new physical sintering model: the main mechanism for oxide nuclear shrinkage is the plastic flow of the matter under internal stress and capillary forces. 相似文献
