  1. 1. Precise Image-Based Measurements through Irregular Sampling

    Författare :Teo Asplund; Robin Strand; Cris L. Luengo Hendriks; Matthew J. Thurley; Gunilla Borgefors; Hugues Talbot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; image analysis; image processing; mathematical morphology; irregular sampling; adaptive morphology; missing samples; continuous morphology; path opening.; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Mathematical morphology is a theory that is applicable broadly in signal processing, but in this thesis we focus mainly on image data. Fundamental concepts of morphology include the structuring element and the four operators: dilation, erosion, closing, and opening. LÄS MER

  3. 2. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    Författare :Gang Xu; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER

  4. 3. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land

    Författare :Pär-Erik Back; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty; decision analysis; risk; sampling; data worth; soil sampling; contaminated land;

    Sammanfattning : Contaminated soil and groundwater is a problem that has received increased attention in the last decade. Decision-making about investigation strategies, protective actions, and remedial actions is based on sparse and uncertain information, primarily data of contaminant concentrations and geological information.

  5. 4. Sampling from a suction induced mini-erosion in human skin. Methodological studies

    Författare :Christer Svedman; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular permeability; neurogenic inflammation; glucose; diabetes mellitus; interstitial fluid; transdermal; skin; sampling; Medicine human and vertebrates ; Medicin människa och djur ;

    Sammanfattning : Dermal interstitial fluid (IF) was extracted serially and painlessly by brief suction for as long as 6 days. The erosion was otherwise kept occluded, Sample volumes exceded those required for measuring a wide range of biological substances. Epidermal regeneration was rapid. LÄS MER

  7. 5. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management

    Författare :Fredrik Östrand; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; effective sampling area; mark-release-recapture; climate; longevity; sampling range; Symphyta; Hymenoptera; monitoring; dispersal; polyandry; mating disruption; integrated pest management; behaviour; sex pheromone; Neodiprion sertifer; Diprionidae; Djurekologi; Zoology; Zoologi; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik;

    Sammanfattning : Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. LÄS MER
