In my latest article, we present a powerful direct approach to simplify complexly structured nonlinear systems with external periodic excitation via normal forms. This approach is liberated from special treatment of nonlinear systems such as ‘book-keeping’ parameters, detuning parameters etc. It does not mandate the system to be minimally excited and the system may possess […]Read more "Simplifying Nonlinear Systems With External Periodic Excitation"
In my latest journal article I have a mouthwatering treat in; gravity gradient attitude stabilization, periodic nonlinear spacecraft attitude dynamics, Chebyshev polynomials, Hopf bifurcation, sliding mode control, Lyapunov-Floquet transformation, Normal Forms, system state augmentation etc. The article titled ” Control of Nonlinear Spacecraft Attitude Motion via State Augmentation, Lyapunov-Floquet Transformation and Normal Forms ” is […]Read more "Control of nonlinear spacecraft attitude dynamics"

After a protracted process stretching beyond 5 years, the African Union (AU) Space Working Group delivered the African Space Policy document late last year (African Space Strategy V10_1). This document was subsequently adopted by African education, science and technology ministers and is expected to be approved by the AU Heads of States Summit in January 2016. This is […]Read more "African Space Policy"
African moon mission seeks cash for first phase By Paula Park A group of African space enthusiasts have taken to the internet to raise money for what they say will be the continent’s first moon mission. Africa2Moon’s main goal is to send a probe to orbit or land on the moon and beam back video […]Read more "African Space Technology Initiatives"
Following the brutal attacks at Westgate Mall in Nairobi, I would like to convey my heart-felt condolences to the family and friends of the victims. This inexplicable and despicable beastly act occurred on 21st September 2013. May the fallen RIP and we pray for a rapid and wholesome recovery for the survivors. May God further […]Read more "Westgate Mall Attack"
