Planar micro-optic solar concentrator We gift a brand new approach to star concentration wherever daylight collected by every lens in a very two-dimensional lens array is coupled into a shared, placoid conductor exploitation localized options placed at every lens focus. This pure mathematics yields a skinny, flat profile for moderate concentration systems which can be […]

Thermal radiation from the atmosphere A theoretical analysis of atmospheric thermal radiation reveals that previous formulation concerning this parameter to screen‐stage air temperature have lacked accepted applicability. New concerns indicate that the effective emittance of the atmosphere is a minimal at 273°K and that it will increase symmetrically to method harmony exponentially at better and […]

In this study, we revisit the concept of classical capacitor theory-and derive a possible new explanation of the definition charge stored in a capacitor. We introduce a ‘capacity function’ with respect to time to describe the charge storage in a classical capacitor and for a fractional capacitor. The observation regarding capacitor breakdown is very interesting. […]

The study presents the results of experimental data showing seasonal variability of rainfall intensities at two locations in Nigeria. The increasing development in satellite technology has brought about several novel mobile satellite services and applications. Consequently, there is a pressing demand for seamless data transfer and accessibility to satellite-earth microwave links in SHF/EHF frequency bands. […]

Polycarbonate (PC) is the most widely used aromatic polymer in various industrial applications. It is a condensation polymer in which benzene rings plus quaternary carbon atoms form bulky stiff molecules that promote rigidity and strength. The bulky chains crystallize with great difficulty, so the polymer is normally amorphous with excellent characteristics such as optical clarity, […]
