The Internet in East Africa: a mixed methods study
(East African Journal of Science, Technology and Innovation, 2020)East Africa was the last major area of the world to gain access to the Internet when submarine fibre-optic cables landed at Mombasa, Kenya and Dar-es-Salaam, Tanzania in 2009. The region previously relied on satellite ... -
Enabling models of Internet eXchange Points for developing contexts
(Elsevier, 2020-10-24)In 2009, fibre-optic cables landed on the East coast of Africa, the last major area of the world to be connected to the Internet triggering a decade of Internet development (Graham et al., 2015). During the same period, ... -
Oblique Detonation Wave Control with O3 and H2O2 Sensitization in Hypersonic Flow
