  1. 11. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

    Författare :Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. LÄS MER

  3. 12. Architecture and function of the insulin granule secretion machinery

    Författare :Peng Yin; Sebastian Barg; Herbert Gaisano; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Docking; Syntaxin-1A; Voltage-gated Ca2 Channels; Exocytosis; Type-2 Diabetes;

    Sammanfattning : Insulin is released into the blood stream to normalize elevated blood glucose, for example after a meal. The hormone is synthesized by β-cells in the endocrine pancreas, and stored in small vesicles, known as secretory granules, until required. When glucose is elevated, these granules undergo regulated exocytosis and thereby secrete the hormone. LÄS MER

  4. 13. Chaperone/usher machinery : a catalyst of virulence organelle assembly

    Författare :Xiaodi Yu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Many virulence organelles of Gram-negative bacterial pathogens are assembled via the periplasmic chaperone/usher (CU) pathway. The assembly process is a complex task, involving secretion of organelle subunits via the two membranes and periplasm, subunit folding and assembly. LÄS MER

  5. 14. On Electric Machinery for Integrated Motor Drives in Automotive Applications

    Författare :Hui Zhang; Oskar Wallmark; Torbjörn Thiringer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Compact, electric drives for automotive traction applications represent animportant enabler towards realizing tomorrow’s fossil free transport solutions.One attractive solution is to integrate the power electronic converter withits associated electric machinery into a single unit.

  7. 15. Precision measurement instruments for machinery's mechanical compliance: design and operation : Measurement instruments for physics-based calibration of advanced manufacturing machinery

    Författare :Nikolas Alexander Theissen; Andreas Archenti; Alexander Slocum; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement instruments; Machine tools; Industrial robots; Production Engineering; Industriell produktion;

    Sammanfattning :  Precision Measurement Instruments (PMIs) for machinery’s mechanical compliance are tools to quantify mechanical load as well as length for measurement ranges of 0.1 µm to 10 m at uncertainty levels of 0.1 µm to 100 µm while exerting mechanical loads. LÄS MER
