  1. 16. Hydraulic transformers for energy efficient systems

    Författare :Ronnie Werndin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : THE FOCUS OF this thesis is to evaluate and analyse secondary controlled hydraulic systems with linear loads. The main objective has been the hydraulic transformer, with special respect to Innas Hydraulic Transformer, IHT1. LÄS MER

  3. 17. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Författare :Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. LÄS MER

  4. 18. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques

    Författare :Andreas Sembrant; David Black-Schaffer; Erik Hagersten; David A. Wood; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. LÄS MER

  5. 19. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

    Författare :Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

    Sammanfattning : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. LÄS MER

  7. 20. VO2-based Thermochromic and Nanothermochromic Materials for Energy-Efficient Windows : Computational and Experimental Studies

    Författare :Shuyi Li; Claes-Göran Granqvist; Gunnar Niklasson; Ivan Parkin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VO2; thermochromism; nanothermochromics; energy efficient windows; optical modeling; effective medium theory; thin film characterization; doping;

    Sammanfattning : VO2-based films are thermochromic and exhibit high or low infrared transmittance when the temperature is below or above a critical temperature. The thermochromic switching is passive and reversible, and therefore VO2 based films are promising for energy-efficient window appli­cations. LÄS MER
