EFFECTS OF SOME PARAMETERS ON THERMAL CONTROL OF A LEO SATELLITE

Effects of Some Parameters on Thermal Control of a LEO Satellite

Satellite thermal control ensures safe operating temperature ranges for satellite components throughout the mission life.Effects of altitude, spin, and position of satellite radiator(s) on the thermal control of a small Low Earth Orbit (LEO) satellite have been Meat Slicers studied.Results show that change in satellite altitude, in the range consid

Micro-Environmental Stress Induces Src-Dependent Activation of Invadopodia and Cell Migration in Ewing Sarcoma

Metastatic Ewing sarcoma has a very poor prognosis and therefore new Lighters investigations into the biologic drivers of metastatic progression are key to finding new therapeutic approaches.The tumor microenvironment is highly dynamic, leading to exposure of different regions of a growing solid tumor to changes in oxygen and nutrient availability.

A direct integral pseudospectral method for solving a class of infinite-horizon optimal control problems using Gegenbauer polynomials and certain parametric maps

We present a novel direct integral pseudospectral (PS) method (a direct IPS method) for solving a class of continuous-time infinite-horizon optimal control problems (IHOCs).The method transforms the IHOCs into finite-horizon optimal control problems in their integral forms by means of certain parametric mappings, which are then approximated by fini
