1. 11. Towards adaptive bogie design

   Författare :Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Optimization; suspension system; bogie; active control;

   Sammanfattning : Suspension components play a crucial role in bogie dynamics behavior. In this regard, passive and active systems are developed to meet various design requirements. Adaptive suspension systems can adjust the bogie dynamics with respect to different operational scenarios and as a result improve the vehicle performance. LÄS MER

3. 12. Hierarchical Real Time Scheduling and Synchronization

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

   Sammanfattning :   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. LÄS MER

4. 13. Progress in Hierarchical Clustering & Minimum Weight Triangulation

   Författare :Drago Krznaric; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer technology; Systems engineering; minimum spanning tree; complete linkage; hierarchical clustering; minimum weight triangulation; greedy triangulation; Data- och systemvetenskap;

   Sammanfattning : In this thesis we study efficient computational methods for geometrical problems of practical importance and theoretical interest. The problems that we consider are primarily complete linkage clustering, minimum spanning trees, and approximating minimum weight triangulation. Below is a list of the main results proved in the thesis. LÄS MER

5. 14. Hierarchical Concurrent Systems from a Model-Oriented perspective

   Författare :Daniel Einarson; Data Vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap;

   Sammanfattning : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. LÄS MER

7. 15. Challenges in aero engine performance modeling

   Författare :Sebastian Samuelsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; part-load modeling; Aero engine; conceptual design; performance modeling; multidisciplinary design;

   Sammanfattning : There is a continuous drive for ever more efficient aero engines due to environmental as well as economical concerns. As the technology of conventional turbofan engines matures, there is a need for new aero engine concepts as well as incremental improvement of existing technologies. LÄS MER
