Determination Of The Density And The Damping Properties Of Polyethylene (Pe) And Polylactic (Pla) Films Using Dma
(2013-08)Damping which is an effect that tends to reduce the amplitude of oscillations in an oscillatory system is significant in components under high dynamic loads especially in general mechanical engineering. In this study, ... -
Distribution of Spectrum in a Direct Sum Decomposition of Operators into Normal and Completely Non normal parts;
(Modern Scientific Press Company, Florida, USA, 2014-09-05)We discuss the distribution of spectra of a direct sum decomposition of an arbitrary operator into normal and completely non normal parts. We utilize the fact that any given operator 𝑇∈𝐵(𝐻) can be ... -
Ecological restoration of pastoral landscapes in the drylands of East Africa
(Journal of Dryland Agriculture, 2021-01-26)The East African drylands cover about 47% of the land surface and host about 20 million people. Rural people living in the drylands are mainly pastoralists who depend on livestock for both economic and social well-being. ... -
“Effect of AC Helmholt magnetic field on the mass of Rosecoco deans”
(Taylor and Francis Online, 2011-06-09)Plastic bags mostly made of polyethylene (PE) cause pollution as solid waste due to their non-degradability nature. Initiation of a degradative process by enhanced photo-oxidation is a possible method for an accelerated ... -
The Effect of Adaptive Learning Rate on the Accuracy of Neural Networks
((IJACSA) International Journal of Advanced Computer Science and Applications, 2021)Learning rates in gradient descent algorithms have significant effects especially on the accuracy of a Capsule Neural Network (CNN).
