Comment-based concept location over system dependency graphs

Software maintenance is one of the most expensive phases of software development and understanding a program is one of the most important tasks of software maintenance. Before making the change to the program, software engineers need to find the location, or locations, where the changes will be made, they need to understand the program. Real applications are huge, sometimes old, were written by other person and...

A influência de um campo magnético estático no escoamento sanguíneo com nanopar...

De forma a realizar estudos de escoamentos em microcanais e avaliar a influência das nanopartículas, sob a ação de um campo magnético estático, na espessura da camada de plasma, foram produzidas nanoparticulas de óxido de ferro por síntese solvotérmica, sendo posteriormente colocadas em suspensão num fluido fisiológico constituído por eritrócitos. Verificou-se que as nanopartículas com características magnética...

Networked embedded systems for active flow control in aircraft

Aerodynamic 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...

CoS: a new perspective of operating systems design for the cyber-physical world

Our day-to-day life is dependent on several embedded devices, and in the near future, many more objects will have computation and communication capabilities enabling an Internet of Things. Correspondingly, with an increase in the interaction of these devices around us, developing novel applications is set to become challenging with current software infrastructures. In this paper, we argue that a new paradigm fo...

Building a microscope for the data center

Managing the physical and compute infrastructure of a large data center is an embodiment of a Cyber-Physical System (CPS). The physical parameters of the data center (such as power, temperature, pressure, humidity) are tightly coupled with computations, even more so in upcoming data centers, where the location of workloads can vary substantially due, for example, to workloads being moved in a cloud infrastructu...

Enhancing the real-time capabilities of the Linux Kernel

The mainline Linux Kernel is not designed forhard real-time systems; it only fits the requirements of soft realtimesystems. In recent years, a kernel developer communityhas been working on the PREEMPT-RT patch. This patch(that aims to get a fully preemptible kernel) adds some realtimecapabilities to the Linux kernel. However, in terms ofscheduling policies, the real-time scheduling class of Linux islimited to t...

Sob: sonhar no cinema

Trabalho de Projeto apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Ciências da Comunicação ; Contém um filme com anexo ; A imersão desencadeada no encontro com uma obra cinematográfica é do domínio do sonho. Os estímulos do Cinema reproduzem o mecanismo da fantasia, do "sonhar acordado", da suspensão da realidade numa dimensão onírica. A reflexão teórica e a curta-metr...
