    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry;

    Abstract : For integration of additive manufacturing into industrial production, there is a need for capable yet robust automation solutions. Such solutions are to ensure consistent process outputs, both with regard to deposit geometry and material properties. READ MORE

  2. 2. Insulin signalling in human adipocytes mechanisms of insulin resistance in type 2 diabetes

    University dissertation from Institutionen för klinisk och experimentell medicin

    Author : Anna Danielsson; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipocytes; type 2 diabetes; insulin; insulin resistance; insulin signalling; phosphorylation; insulin receptor substrate 1; feedback control; MEDICINE Morphology; cell biology; pathology Cell biology Medical cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi Medicinsk cellbiologi;

    Abstract : Prevalensen av fetma ökar drastiskt i stora delar av världen och utgör en stor riskfaktor för att utveckla insulinresistens och typ 2 diabetes. Fettväven kan bli mycket stor om för mycket energi tas upp av kroppen. READ MORE

  3. 3. Instrumentation and estimation for high temperature control

    University dissertation from Göteborg : Chalmers Reproservice

    Author : Petter Hagqvist; Högskolan Väst.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Physics; Fysik; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry; Varying Emissivity;

    Abstract : Within a variety of industrially relevant high temperature production processes such as welding, heat treatment and metal deposition, the quality of the manufactured component is largely affected by how well parameters can be controlled during processing. These parameters might be, in the case of metal deposition, power input, material feed, or a parameter which is common for all of the aforementioned processes: material temperature. READ MORE

  4. 4. Fat cell insulin resistance an experimental study focusing on molecular mechanisms in type 2 diabetes

    University dissertation from Umeå : Folkhälsa och klinisk medicin

    Author : Frida Renström; Umeå universitet.; [2007]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipocyte; insulin signaling; insulin; glucose; IRS-1; glucose uptake; insulin resistance; typ 2 diabetes; serum; VETERINARY MEDICINE Medicine; VETERINÄRMEDICIN Medicin;

    Abstract : The aim of the present thesis was to further increase our understanding of mechanisms contributing to and maintaining cellular insulin resistance in type 2 diabetes (T2D). For this reason, the effects of high glucose and insulin levels on glucose transport capacity and insulin signaling, with emphasis on insulin receptor substrate 1 (IRS-1) were assessed in fat cells.

  5. 5. Microwave power device characterization

    University dissertation from Umeå : Folkhälsa och klinisk medicin

    Author : Kristoffer Andersson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical estimation; self-heating; Silicon Carbide; Gallium Nitride; mixer; thermal resistance; wide bandgap; microwave; error-correction; small-signalmodel;

    Abstract : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. READ MORE
