2. 1. Hierarchical scheduling for predictable execution of real-time software components and legacy systems

   Author : Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Moris Behnam; Giuseppe Lipari; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component integration and reuse; hierarchical scheduling; multicore; Computer Science; datavetenskap;

   Abstract : This dissertation presents techniques to achieve predictable execution of coarse-grained software components and for preservation of temporal properties of components during their integration and reuse.The dissertation presents a novel concept runnable virtual node (RVN) which interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behaviour is preserved when integrated with other components or when reused in a new environment.

4. 2. Hierarchical Real Time Scheduling and Synchronization

   Author : Moris Behnam; Mikael Sjödin; Thomas Nolte; Björn Andersson; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer engineering; Datorteknik; Datavetenskap;

   Abstract :   The Hierarchical Scheduling Framework (HSF) has been introduced to enable compositional schedulability analysis and execution of embedded software systems with real-time constraints. In this thesis, we consider a system consisting of a number of semi-independent components called subsystems, and these subsystems are allowed to share logical resources. READ MORE

5. 3. Hierarchical energy management in smart grids : Flexibility prediction, scheduling and resilient control

   Author : Kaveh Paridari; Lars Nordström; Henrik Sandberg; Geert Deconinck; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Abstract : The electric power industry and society are facing challenges and opportunitiesof transforming the present power grid into a smart grid. Energymanagement systems (EMSs) play an important role in smart grids. A generalhierarchical structure for EMSs is considered here, which is composed ofa lower layer and an upper layer. READ MORE

6. 4. Hierarchical Scheduling and Utility Disturbance Management in the Process Industry

   Author : Anna Lindholm; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant-wide disturbances; utilities; production control; production scheduling; process industry; enterprise modeling; availability; receding horizon control;

   Abstract : This thesis deals with control of production at large-scale process industrial sites in the presence of disturbances. The main focus is on disturbances in the supply of utilities such as steam, cooling water and electricity. READ MORE

7. 5. Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

   Author : Traian Pop; Petru Ion Eles; Zebo Peng; Luis Almeida; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distributed embedded systems; Real-time analysis; Scheduling; Design optimisation; FlexRay; Computer and systems science; Data- och systemvetenskap;

   Abstract : The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. READ MORE
