Experimental investigations on the performance of a flat plate solar air heater (SAH) with brown sand as absorber and clear HDPE paper as top cover was done. The efficiency, heat gain factor and heat loss coefficient were ...
ABSTRACT: We prove the existence of an asymptotically stable periodic solution of a system of
delay differential equations with a small time delay τ > 0. To achieve this, we transform the system
of equations into a ...
