The correct orientation of the spacecraft during a space flight is one of the main tasks of astronautics,because its orientation affects the correct operation of all subsystems, in particular power supply systems,where the orientation of solar panels is one of the key tasks. From this point of view, the tasks of developingbackup or replacement of orientation systems are becoming relevant. In this...
The aim of this paper is to compare the performance of four deep convolutional neural networks in theproblem of image-based automated detection of concrete surface cracks in the case of a small dataset. Thiscrack detection problem is treated as a binary classification problem, and it is solved by training a deepconvolutional neural network on the small dataset. In this context, overfitting during...
The method presented in this paper allows the visualization of spatial relations that could not be obtainedusing existing methods. Depending on the component maps that represent the analysis criteria, it ispossible to indicate certain ways to develop good or bad areas. These maps may contain visibility dataas well as other types of spatial impact. Thanks to this, spatial decision criteria can be broad...
In this work, a three-dimensional simplified computational model was built to simulate the passive thermo-physiological response of part of a newborn’s head for neonate’s selective brain cooling. Both metabolicheat generation and blood perfusion were considered. The set of model parameters was selected anda sensitivity study was carried out. Analysis of dimensionless sensitivity coefficients showed...
