Optimal law for inclination change in an atmosphere through solar sailing

Optimal slope and azimuth analysis for photovoltaic panels based on solar radiation in Kashan

One of the most important parameters in maximal use of radiant energy is the proper deployment of photovoltaic. The purpose of this study was to determine the optimum setting and tilt for installing photovoltaic panel in Kashan city. For this purpose, using the Masters Gilbert physical relations and relationships, the radiation received on the surface of the panel is calculated. The results of ...

Circumplanetary Dust Dynamics: Effects of Solar Gravity, Radiation Pressure, Planetary Oblateness, and Electromagnetism

are similar in strength, which greatly complicates the resulting orbital dynamics. Analytic approaches to these We consider the motions of circumplanetary objects perturbed simultaneously by solar gravity, radiation pressure, problems have been limited to cases where orbital eccenplanetary oblateness, and electromagnetic forces. Confining tricities remain small. The interplay between like-sized...

Controllable Propulsion by Light: Steering a Solar Sail via Tunable Radiation Pressure

(1 of 6) 1600668 polymer dispersed liquid crystal (PDLC) films stand out due to their ability to be switched from an opaque to a transparent state with the applied external electric field without the need for polarizers. Since its discovery,[13] researchers have extensively explored the potential applications of PDLCs in the areas of flat panel displays,[14] smart windows,[15,16] microlens,[17]...

Modeling and Optimal Control of 4 Wheel Steering Vehicle Using LQR and its Comparison with 2 Wheel Steering Vehicle

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...
