Networked embedded systems for active flow control in aircraft
Tovar, Eduardo; Pereira, Nuno; Bate, Iain; Indrusiak, Leandro; Penna, Sérgio; Negrão, José; Viana, Júlio C.; Philipp, François; Mayer, Dirk; Heras, JoséAerodynamic drag is known to be one of the factors contributing more to increased aircraft fuel consumption. The primary source of skin friction drag during flight is the boundary layer separation. This is the layer of air moving smoothly in the immediate vicinity of the aircraft. In this paper we discuss a cyber-physical system approach able of performing an efficient suppression of the turbulent flow by using...
On the evolution of remote laboratories for prototyping digital electronic systems
Indrusiak, Leandro Soares; Glesner, Manfred; Reis, Ricardo Augusto da LuzThe design of digital electronic systems for industrial applications can benefit in many ways from the prototyping capabilities of field-programmable gate array (FPGA) platforms. This paper presents three evolutionary releases of an FPGA-based remote laboratory and discusses the didactical and technical motivations behind each release, aiming to reduce the overhead of setting up and operate a laboratory environ...
Um Framework de apoio à colaboração no projeto distribuído de sistemas integrados
Indrusiak, Leandro Soares; Reis, Ricardo Augusto da Luz; Glesner, ManfredO trabalho de pesquisa apresentado neste artigo tem por objetivo possibilitar a distribuição flexível de recursos e ferramentas de apoio ao projeto de sistemas integrados, considerando especificamente a necessidade de interação colaborativa entre os projetistas. O trabalho enfatiza particularmente alguns problemas que foram considerados apenas marginalmente em abordagens anteriores, como a abstração da distribu...
