Counting independent terms in big-oh notation
Fabiano de S. Oliveira, Valmir C. Barbosa
The field of computational complexity is concerned both with the intrinsic hardness of computational problems and with the efficiency of algorithms to solve them. Given such a prob…
Quasispecies dynamics on a network of interacting genotypes and idiotypes: Applications to autoimmunity and immunodeficiency
Valmir C. Barbosa, Raul Donangelo, Sergio R. Souza
In spite of their many facets, the phenomena of autoimmunity and immunodeficiency seem to be related to each other through the subtle links connecting retroviral mutation and actio…
Detecting and Handling Flash-Crowd Events on Cloud Environments
Ubiratam de Paula, Daniel de Oliveira, Yuri Frota +2
Cloud computing is a highly scalable computing paradigm where resources are delivered to users on demand via Internet. There are several areas that can benefit from cloud computing…
Adaptive event sensing in networks of autonomous mobile agents
Rodrigo R. Esch, Fábio Protti, Valmir C. Barbosa
Given a connected region in two-dimensional space where events of a certain kind occur according to a certain time-varying density, we consider the problem of setting up a network…
Scheduling wireless links by graph multicoloring in the physical interference model
Fabio R. J. Vieira, José F. de Rezende, Valmir C. Barbosa
Scheduling wireless links for simultaneous activation in such a way that all transmissions are successfully decoded at the receivers and moreover network capacity is maximized is a…
