Risk-averse feasible policies for large-scale multistage stochastic linear programs
(Springer Heidelberg, 2013-04)
We consider risk-averse formulations of stochastic linear programs having a structure that is common in real-life applications. Specifically, the optimization problem corresponds to controlling over a certain horizon a ...
Local Linearization-Runge-Kutta methods: a class of A-stable explicit integrators for dynamical systems
(Pergamon-Elsevier Science Ltd, 2013-02)
A new approach for the construction of high order A-stable explicit integrators for ordinary differential equations (ODEs) is theoretically studied. Basically, the integrators are obtained by splitting, at each time step, ...
Participation in discussion spaces of health informatics in Brazil
(Springer-Verlag Berlin, 2013)
This work analyses instances of discussion related to the Brazilian public policy on health information and communication technologies (ICT). Departing from a theoretical model, which relates health ICT outcomes to instances ...
Examining sources of resistance to the implementation of a patent management system in a developing country: evidence from a case study of the Brazilian Patent Office
(Springer-Verlag Berlin, 2013)
User resistance to information systems implementation has been identified as a significant reason for the failure of new systems and hence needs to be understood and managed. While previous research has explored the reasons ...
A simulation-based approach to analyze the information diffusion in Microblogging Online Social Network
(IEEE, 2013)
In this paper we propose a stochastic multi-agent based approach to analyze the information diffusion in Microblogging Online Social Networks (OSNs). OSNs, like Twitter and Facebook, became extremely popular and are being ...
Patience-aware scheduling for cloud services: freeing users from the chains of boredom
(Springer-Verlag Berlin, 2013)
Scheduling of service requests in Cloud computing has traditionally focused on the reduction of pre-service wait, generally termed as waiting time. Under certain conditions such as peak load, however, it is not always ...
Managerial action and sensemaking in e-learning implementation in Brazilian business schools
(Pergamon-Elsevier Science Ltd, 2012-12)
The existing literature on e-learning implementation is either descriptive or normative and falls short on explaining how managers act in introducing and disseminating e-learning projects in school settings. In this paper, ...
Numerical multiscale methods
(Wiley-Blackwell, 2012-10-10)
We restrict the variational multiscale method to a class of methods we denote by numerical multiscale methods. Numerical multiscale methods are methods obtained by enriching the piecewise linear functions with special local ...
Affine properties of convex equal-area polygons
(Springer, 2012-10)
In this paper we discuss some affine properties of convex equal-area polygons, which are convex polygons such that all triangles formed by three consecutive vertices have the same area. Besides being able to approximate ...
O início, o fim e o meio digital: cobertura, capacidades e convergência
(2012-07-01)
Este estudo acompanha a difusão de diferentes Tecnologias de Informação e Comunicação (TICs) na sociedade, tal como enxergadas pelas bases de dados disponíveis a começar pelo Censo 2000 até hoje. Mapeamos o uso das TICs ...
