Gastvortrag
am 12. Oktober 2004 hielt Herr Prof. Dr. Andrea Bondavalli von der University of Firenze
Faculty of Science,I-50134 Firenze, (Italien)
einen Vortrag zum Thema
"Quantitative Analysis through Modeling of Large Scale Telecommunication
Systems"
Abstract:
This talk deals with the quantitative analysis of large scale
telecommunication systems, focusing on the GPRS technology. A congestion
analysis of a simple GPRS network , composed by two cells partially
overlapping, is first presented. In particular, we consider that one of the
two cells is affected by an outage and we analyze the
effectiveness of applying a class of congestion treatment techniques. The
effectiveness of a reconfiguration action is evaluated in terms of
indicators that represent the Quality of Service (QoS) perceived by the
users in the congested cells. In the second part of this talk, we extend the
congestion analysis to a more complex GPRS infrastructure composed by N
cells partially overlapping. In order to efficiently solve this complex
scenario, we introduce a resolution technique that overcomes the system
complexity problem by decomposing the overall model in a set of more simple
and easier to solve models. |

einen Vortrag zum Thema
"Impact of Real-Time Scheduling Algorithms on Design of Embedded Applications"
Abstract:
This work evaluates how distinct real-time task scheduling algorithms impact embedded systems design, considering issues like performance, energy consumption, timing response, and memory occupation. This study shows that the designer can adjust the energy consumption of the system by tuning the CPU frequency according to the scheduling algorithm and to the temporal requirements of the embedded application. The goal is to find an optimized configuration, selecting the right combination of scheduling policy with CPU frequency, in order to consume less energy without missing any deadline in the application. Experiments based on a
synthetic workload that simulates realistic applications demonstrate that considerable energy savings (up to 18%) can be obtained by using the EDF algorithm. The work also discusses in which situations RM performs better than EDF. Moreover, the work defines guidelines to be used by system designers in order to find a configuration that best matches the design constraints and requirements. |

am 04.12.2002 hielt Herr Prof. Carlos Eduaro
Pereira von der Federal University of Rio Grande do Sul (Brasilien)
einen Vortrag zum Thema
"Distributed real-time object computing"
Abstract:
The talk gives an overview on research being carried on at the Automation
Lab of the Federal University of Rio Grande do Sul in Brazil, mainly focusing
on the use of real-time distributed objects to the development of industrial
automation applications. The group has an extensive experience in applying
object-oriented concepts (with real-time extensions) as a theoretical basis
for modeling, simulation, and implementation of real-time distributed computer-based
architectures.
The talk will also present the Adoorata project, an ongoing collaborative
research project between Germany and Brazil, which includes GCAR/UFRGS
and University of Magdeburg. |
