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 […]

2015 in review

Happy 2016! Here is the 2015 annual statistics report. Here’s an excerpt: A matatu  holds 30 people. This blog was viewed about 3,400 times in 2015. If it were a matatu, it would take about 115 trips to carry that many people. Click here to see the complete report.

Kenya has courageously embarked on a path to transform herself into a newly industrialized country by 2030 through the long-term planning strategy officially named Kenya Vision 2030. To achieve this development objective, Kenya will have to be audacious, ingenious and entrepreneurial as a state in formulating solutions to the developmental challenges ahead. Space-based technology has […]
