Two ways to deduce the equivalence of field equations general relativity and principle maximum force $c^4/4G$ - or equivalent power $c^5/4G$ are presented. A simple deduction inverse square gravity directly from arises. Recent apparent counterarguments refuted. New tests in astronomy, cosmology, electrodynamics, numerical gravitation quantum proposed.

in this study, the performance of an irreversible regenerative brayton cycle is sought through power maximizations using finite-time thermodynamic concept in finite-size components. optimizations are performed using a genetic algorithm. in order to take into account the finite-time and finite-size concepts in the current problem, a dimensionless mass-flow rate parameter is used to deploy time v...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

In this paper, we present a comparative study of single sensor-based maximum power point tracking (MPPT) techniques for solar photovoltaic (PV) water pumping systems. A conventional hill climbing algorithm is employed to find and track the MPP, using the information obtained from either a voltage sensor or a tachometer or a manometer. The results of experiment are included and explained to vali...
