  2. 21. Deterministic, Explainable and Resource-Efficient Stream Processing for Cyber-Physical Systems

    Author : Dimitrios Palyvos-Giannas; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Provenance; Stream Processing; Scheduling; Determinism;

    Abstract : We are undeniably living in the era of big data , where people and machines generate information at an unprecedented rate. While processing such data can provide immense value, it can prove especially challenging because of the data's Volume, Variety and Velocity . READ MORE

  4. 22. Analysing, modelling and controlling power-performance tradeoffs in data center infrastructures

    Author : Jakub Krzywda; Erik Elmroth; Per-Olov Östberg; Ahmed Ali-Eldin; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The aim of this thesis is to analyse the power-performance tradeoffs in datacenter servers, create models that capture these tradeoffs, and propose controllers to optimise the use of data center infrastructures taking the tradeoffs into consideration. The main research problem that we investigate in this thesis is how to increase the power efficiency of data center servers taking into account the power-performance tradeoffs. READ MORE

  5. 23. A software system for defining and controlling actions in a mechanical system

    Author : Johan Hultman; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the subject of technical systems where machinery, usually of mechanical character, are controlled by a computer system. Sensors in the system provide information about a machine’s current state, and are crucial for the controlling computer. READ MORE

  6. 24. Intrinsic Formation and Macroscopic Intervention in Multi-agent Systems

    Author : Silun Zhang; Xiaoming Hu; Johan Karlsson; Jorge Goncalves; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attitude control; agents and autonomous systems; distributed control; formation control; nonlinear systems; moment based modelling; large- scale systems; reduced order modeling; nonlinear system identification; Mathematics; Matematik;

    Abstract : In this dissertation, we study two problems within the field of the multi-agent systems theory. One is the formation control for multiple reducedattitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. READ MORE

  7. 25. Timing and Schedulability Analysis of Real-Time Systems using Hidden Markov Models

    Author : Anna Friebe; Thomas Nolte; Alessandro Papadopoulos; Filip Markovic; Liliana Cucu-Grosjean; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : In real-time systems functional requirements are coupled to timing requirements, a specified event needs to occur at the appropriate time.  In order to ensure that timing requirements are fulfilled, there are two main approaches, static and measurement-based. READ MORE
