1. 1. Scheduling and Optimization of Fault-Tolerant Embedded Systems

   Författare :Viacheslav Izosimov; Zebo Peng; Petru Eles; Anton Cervin; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded systems; Real-Time systems; Design optimization; Fault tolerance; Transient faults; Soft errors; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : Safety-critical applications have to function correctly even in presence of faults. This thesis deals with techniques for tolerating effects of transient and intermittent faults. Reexecution, software replication, and rollback recovery with checkpointing are used to provide the required level of fault tolerance. LÄS MER

3. 2. Improving Soft Real-time Performance of Fog Computing

   Författare :Vaclav Struhar; Moris Behnam; Seyed Mohammad Hossein Ashjaei; Alessandro Papadopoulos; Silviu Craciunas; Ivona Brandic; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fog computing; real-time systems; cloud; virtualization; Computer Science; datavetenskap;

   Sammanfattning : Fog computing is a distributed computing paradigm that brings data processing from remote cloud data centers into the vicinity of the edge of the network. The computation is performed closer to the source of the data, and thus it decreases the time unpredictability of cloud computing that stems from (i) the computation in shared multi-tenant remote data centers, and (ii) long distance data transfers between the source of the data and the data centers.

4. 3. Verification and Scheduling Techniques for Real-Time Embedded Systems

   Författare :Luis Alejandro Cortés; Zebo Peng; Petru Eles; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer systems; Embedded computer systems; real-time systems; Computer science; Datavetenskap;

   Sammanfattning : Embedded computer systems have become ubiquitous. They are used in a wide spectrum of applications, ranging from household appliances and mobile devices to vehicle controllers and medical equipment. LÄS MER

5. 4. Scheduling Garbage Collection in Embedded Systems

   Författare :Roger Henriksson; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; memory management; garbage collection; real-time; embedded systems; hard deadlines; run-time systems; Systems engineering; scheduling analysis; Data- och systemvetenskap; computer technology;

   Sammanfattning : The complexity of systems for automatic control and other safety-critical applications grows rapidly. Computer software represents an increasing part of the complexity. As larger systems are developed, we need to find scalable techniques to manage the complexity in order to guarantee high product quality. LÄS MER

7. 5. Developing Reusable and Reconfigurable Real-Time Software using Aspects and Components

   Författare :Aleksandra Tešanović; Jörgen Hansson; Heinz W. Schmidt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; embedded systems; software components; aspect-oriented software; quality of service; worst-case execution time; database systems; Software engineering; Programvaruteknik;

   Sammanfattning : Our main focus in this thesis is on providing guidelines, methods, and tools for design, configuration, and analysis of configurable and reusable real-time software, developed using a combination of aspect-oriented and component-based software development. Specifically, we define a reconfigurable real-time component model (RTCOM) that describes how a real-time component, supporting aspects and enforcing information hiding, could efficiently be designed and implemented.
