Creep deformation in single-phase ɤ-TiAl alloys manufactured using different processing techniques has been an extensively studied topic owing to the high specific strength and excellent creep properties of these alloys at temperatures between 760 and 1000°C. In addition, these lightweight and creep-resistant alloys are being presently considered as replacements to the comparatively heavier Ni-based...
The last two decades have witnessed a large volume of research revolving around structure–property correlation in carbon-based nanocomposites, synthesized by several methods. The electronic properties of carbon-based nanocomposites vary mainly as a function of the kind of reinforcement, method of synthesis, and structure-dependent parameter. The structure-dependent parameter is highly influenced by...
Sieci neuronowe mogą się pochwalić 75-letnią historią, podczas której wiele się wydarzyło. Początkowe modele sieci neuronowych były oparte wyłącznie na matematyce i algorytmach. Nie można było przetestować ich działania ze względu na ograniczone możliwości ówczesnych maszyn obliczeniowych. Motywacją do przeprowadzenia badań była chęć pokazania rekonstrukcji obrazu z wykorzystaniem zmodyfikowanych...
