    Abstract: This paper presents attitude determination and control of ThinSat system using an adaptive control technique. This study aims to reduce the impact of dynamic torque on the angular velocity and orientation of spacecraft while maintaining a steady position in the axes. This was achieved by collecting the data of Nigeria Sat-2 which was trained with a... Show More

    Abstract: Probability distribution and frequency analysis of rainfall data enable future extreme events. Rainfall is an infrequent and important hydrological parameter on the earth. When designing irrigation and other hydraulic systems, assessing the size of an extreme rainfall event for a specific probability level is extremely important. For the present st... Show More
