3. 2. Scheduling Algorithms For Fault-Tolerant Real-Time Systems

   Författare :Risat Pathan; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Online Scheduling; Partitioned Scheduling; Rate-Monotonic Scheduling; Multiprocessors; Uniprocessor; Task-Splitting Algorithms; Periodic Task Scheduling; Real-Time Systems; Fault-Tolerant Scheduling;

   Sammanfattning : This thesis deals with the problem of designing efficient fault-tolerant real-time scheduling algorithms for independent periodic tasks on uni- and multiprocessor platforms. The well-known Rate-Monotonic (RM) scheduling algorithm is assumed as it is widely used in many commercial systems due to its simplicity and ease of implementation. LÄS MER

4. 3. Design of a fault-tolerant fractional slot PMSM for a vehicle application

   Författare :Christian Dubar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PMSM; Efficiency; Fault-tolerant; Unbalanced operation; Saturation; Fault-tolerance; Fractional slot; Permanent magnet synchronous machine; PMSM ; Concentrated windings;

   Sammanfattning : In automotive applications, the PMSM is an interesting alternative due to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density since it is very important to save especially space but also weight in vehicle applications. LÄS MER

5. 4. Performance Studies of Fault-Tolerant Middleware

   Författare :Diana Szentiványi; Simin Nadjm-Tehrani; Petru Eles; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Programming; aspect-oriented programming; software engineering; distribution transparently; Common Object Request Broker Architecture COBRA ; algorithm; Computer science; Datavetenskap;

   Sammanfattning : Today’s software engineering and application development trend is to take advantage of reusable software. Much effort is directed towards easing the task of developing complex, distributed, network based applications with reusable components. To ease the task of the distributed systems’ developers, one can use middleware, i.e. LÄS MER

7. 5. 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
