1. 1. Towards the Integration of Control and Real-Time Scheduling Design

   Författare :Anton Cervin; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Control; Scheduling; Co-Design; Deadlines; Performance; Simulation; Feedback;

   Sammanfattning : The thesis deals with scheduler and controller co-design for real-time control systems. The overall goal is higher resource utilization and better control performance. One goal is to minimize the performance loss due to jitter and control delays. LÄS MER

3. 2. 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

4. 3. Analysis of Embedded Controllers Subject to Computational Overruns

   Författare :Nils Vreman; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault-tolerance; Real-time systems; Weakly-Hard; Embedded control;

   Sammanfattning : Microcontrollers have become an integral part of modern everyday embedded systems, such as smart bikes, cars, and drones. Typically, microcontrollers operate under real-time constraints, which require the timely execution of programs on the resource-constrained hardware. LÄS MER

5. 4. Human-in-the-Loop Control Synthesis for Multi-Agent Systems under Metric Interval Temporal Logic Specifications

   Författare :Sofie Ahlberg; Dimos Dimarogonas; Knut Åkesson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Agent Systems; Control Synthesis; Hard and Soft Constraints; Human-in-the-Loop; Automatic Control; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With the increase of robotic presence in our homes and work environment, it has become imperative to consider human-in-the-loop systems when designing robotic controllers. This includes both a physical presence of humans as well as interaction on a decision and control level. LÄS MER

7. 5. Performance Aspects of Databases and Virtualized Real-time Applications

   Författare :Christine Niyizamwiyitira; Lars Lundberg; Mikael Svahnberg; Richard Chbeir; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SQL and NoSQL database; Bigdata management systems; Structured and non-structured Database Evaluation; Voice-driven web; Multicore performance prediction; Hard real-time Scheduling; Virtual Multiprocessor Scheduling;

   Sammanfattning : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.
