The developed solutions are employed for investigation of the included parameters on the transient and steady states studies of the moving-porous fin. The results submitted that the fin temperature is augmented with time increase due to increase heat transfer rate as time progresses. However, thermal parameter of the fin reduces from the its base to its tip. As the porosity, moving, convective-conductive-radiative parameters are increased, the fin temperature are decreased due to increased heat transfer rate. The opposite trend is displayed for the conductiveradiative number. It can be stated that present work will be useful in the analysis of the device.

Apart from further confirmation of the roles of equatorial electrojet (EEJ) and integrated equatorial electrojet (IEEJ) in determining hemispheric extent of EIA crest over higher latitudes, we found some additional roles played by thermospheric meridional neutral wind. Interestingly, the simultaneous observations of EIA crests in both hemispheres of Africa-Middle East showed different morphology compared to that reported over Asia. We also observed interesting latitudinal twin EIA crests domiciled at the low latitudes of the Northern Hemisphere. Our results further showed that weak EEJ strength associated with counter electrojet (CEJ) during sunrise hours could also trigger twin EIA crests over higher latitudes.

Finding or calculating the vectors of gains K using pole placement method and performing the closed loop simulations for the non-linear simulink model with a full state feedback controller of gains calculated makes the implementation possible. The controller is implemented by using the gain calculated on the laboratory physical inverted pendulum system. The stability of the simulated and physical laboratory inverted pendulum system was attained. The variations in time taken for the system to attain the upright position may be due to high K value of gains which make the system approach the stability.
