Sommario/riassunto |
|
We cannot imagine life now without a mobile phone' is a frequent comment when Africans are asked about mobile phones. They have become part and parcel of the communication landscape in many urban and rural areas of Africa and the growth of mobile telephony is amazing: from 1 in 50 people being users in 2000 to 1 in 3 in 2008. Such growth is impressive but it does not even begin to tell us about the many ways in which mobile phones are being appropriated by Africans and how they are transforming or are being transformed by society in Africa. This volume ventures into such appropriation and mutu |

Sommario/riassunto |
|
This book provides an approach to the study of perturbation and discretization effects on the long-time behavior of dynamical and control systems. It analyzes the impact of time and space discretizations on asymptotically stable attracting sets, attractors, asumptotically controllable sets and their respective domains of attractions and reachable sets. Combining robust stability concepts from nonlinear control theory, techniques from optimal control and differential games and methods from nonsmooth analysis, both qualitative and quantitative results are obtained and new algorithms are developed, analyzed and illustrated by examples. |
