1. 21. Modeling and Timing Analysis of Industrial Component-Based Distributed Real-time Embedded Systems

   Författare :Saad Mubeen; Mikael Sjödin; Jukka Mäki-Turja; Per Lindgren; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed real-time embedded systems; component-based development; holistic response-time analysis; component model; timing model; Computer Science; datavetenskap;

   Sammanfattning : The model- and component-based development approach has emerged as an attractive option for the development of Distributed Real-time Embedded (DRE) systems. In this thesis we target several issues such as modeling of legacy communication, extraction of end-to-end timing models and support for holistic response-time analysis of industrial component-based DRE systems.

3. 22. Introducing Continuous Experimentation on Resource-Constrained Cyber-Physical Systems

   Författare :Federico Giaimo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber-Physical Systems; Continuous Experimentation; Software Engineering;

   Sammanfattning : Software is ubiquitous and shapes our world, but at the same time it can be viewed as a plastic resource offering the possibility to be improved even after its deployment to better serve its purpose. Exploiting this possibility, the Continuous Experimentation practice is gaining momentum on connected software-intensive web-based systems, allowing the product owners to deploy "experiments" on their software systems, i.

4. 23. Enabling Fast and Accurate Run-Time Decisions in Geo-Distributed Systems : Better Achieving Service Level Objectives

   Författare :Kirill Bogdanov; Dejan Kostic; Gerald Q. Maguire Jr.; Bill Yoshimi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms.; Molntjänster; Geodistribuerade system; Valalgoritmer för replikas; Computer Science; Datalogi;

   Sammanfattning : Computing services are highly integrated into modern society and used  by millions of people daily. To meet these high demands, many popular  services are implemented and deployed as geo-distributed applications on  top of third-party virtualized cloud providers. However, the nature of  such a deployment leads to variable performance. LÄS MER

5. 24. Stability of Adaptive Distributed Real-TimeSystems with Dynamic Resource Management

   Författare :Sergiu Rafiliu; Petru Eles; Zebo Peng; Luigi Palopoli; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; distributed embedded systems; control systems; scheduling; adaptive system;

   Sammanfattning : Today's embedded distributed real-time systems, are exposed to large variations in resource usage due to complex software applications, sophisticated hardware platforms, and the impact of their run-time environment. As eciency becomes more important, the applications running on these systems are extended with on-line resource managers whose job is to adapt the system in the face of such variations. LÄS MER

7. 25. Overload control strategies for distributed communication networks

   Författare :Maria Kihl; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource allocation; simulation models; TINA; Intelligent Networks; distributed systems; performance analysis; overload control; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. LÄS MER
