Simplifying Nonlinear Systems With External Periodic Excitation

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 […]

Control of nonlinear spacecraft attitude dynamics

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 […]

Space Technology and Africa’s Development: The Strategic Role of Small Satellites.

This is a research article I co-authored as part of the Harvard University Kennedy School of Government Research Working Paper Series . It focuses on the theme of Space Technology for Sustainable Development and the unique role played by small satellites. https://www.hks.harvard.edu/publications/space-technology-and-africas-development-strategic-role-small-satellites

Kenya Space Sector Formulation—Phase 4

In this phase, Kenya will begin to transcend to the Operator level from a User level of the space technology capability hierarchy pyramid. This progression will be realized through further expansion of the resources and capacities formerly initiated in the preceding phases. Expanding capabilities will further be augmented by the introduction of completely new competences. […]

Discussion Resumes!

I am delighted that after a brief hiatus, the regular posts and discussions on establishing a space space in Kenya have now resumed. Let us keep the conversation going. The next post will be on Kenya Space Sector Formulation Phase 4.

Kenya Space Sector Formulation—Phase 3

It is in this phase that the physical establishment of the proposed space sector’s infrastructure and tangible capacity commences. A concurrent tripartite approach targeting i) human, ii) organizational and, iii) societal capacity development is required to ensure a comprehensive and efficacious inception of the Kenyan space sector. Similarly, identification and strategic engagement of potential collaboration […]
