Optimal Control Analysis Of The Dynamics Of Covid-19 With Application To Ethiopian Data, Temesgen Duresa Keno, Fekadu Mosisa Legesse, Ebisa Olana Bajira

Applied Mathematics & Information Sciences

In this paper, we proposed an optimal control of the COVID-19 transmission dynamics. First, we investigated system features such as solution boundedness, positivity, disease-free and endemic equilibrium, and the local and global stability of equilibrium points. Besides, a disease-free equilibrium point is globally asymptotically stable if the basic reproduction number is less than one, and an endemic equilibrium point exists otherwise. Secondly, we have shown the sensitivity analysis of the basic reproduction number. Also the model is then fitted using COVID-19 infected reported in Ethiopia from February 1,2023 to March 2,2023. The values of model parameters are then estimated from …

Band-pass filters functioning in the near-infrared (IR) range are desired for laser technology, multi-photon fluorescence, and IR imaging applications. In this study, we have designed four band-pass filters in the near Infrared spectrum (900-1200 nm) by vertically stacking different high and low-index materials. The band-pass filters are modelled by Essential Macleod software with different thicknesses. The layer’s thicknesses were optimized in such a way to provide the negligible reflectance and maximum transmission on the front side.

Reasons Why Oil Reserves Remain Unproductive-A Case Study, Mohamed Al-Saho

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

By studying the production plans of some wells of Al Furat Petroleum Company, the researcher noticed that the rate of production increases to reach a peak and then falls back sharply. The deformation of the area around the well due to the decrease in the formation pressure (after production for a certain period) may have caused a change in the storage properties (porosity, permeability) and thus lower production rate. However, from the point of view of the geomechanics of the oil formation, which includes the study of the stress situation and its effect on the rock tissue, we will notice …
