  1. 11. Flexible automatic memory management for real-time and embedded systems

    Författare :Sven Robertz; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The advent of safe languages like Java on the real-time systems scene motivates further research on efficient strategies for non-intrusive garbage collection and especially GC scheduling. This thesis presents new approaches to flexible and robust memory management from an engineering perspective and is a step towards write once --- run anywhere with hard real-time performance.

  3. 12. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

  4. 13. Automated CNN pipeline generation for heterogeneous architectures

    Författare :Pirah Noor Soomro; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Online tuning; CNN parallel pipelines; Heterogeneous computing units; Processing on chiplets; Design space exploration;

    Sammanfattning : Heterogeneity is a vital feature in emerging processor chip designing. Asymmetric multicore-clusters such as high-performance cluster and power efficient cluster are common in modern edge devices. One example is Intel's Alder Lake featuring Golden Cove high-performance cores and Gracemont power-efficient cores. LÄS MER

  5. 14. Fluorescence as a biological feedback signal for energy optimising spectra for greenhouse LED-illumination

    Författare :Linnéa Ahlman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluorescence; Photosynthesis; Automatic control; Greenhouse illumination; LED lighting; Spectrum optimisation;

    Sammanfattning : The introduction of LED-lighting for greenhouses has enabled new ways of controlling the light, both spectrum and intensity, to save energy and increase crop production. We have investigated a new method of automatically tuning the spectrum based on biological feedback. LÄS MER

  7. 15. Control and Estimation of Automotive Powertrains with Backlash

    Författare :Adam Lagerberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backlash control; powertrain control; driveability; backlash estimation; model predictive control; optimal control; Automatic control;

    Sammanfattning : In automotive powertrains, backlash causes problems with vehicle driveability, specifically at so called tip-in and tip-out maneuvers. These maneuvers may trigger phenomena known in the automotive industry as shunt and shuffle, which are partially caused by the backlash. LÄS MER
