  1. 1. Optimal Detectors for Transient Signal Families and Nonlinear Sensors Derivations and Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Daniel Asraf; Mats Gustafsson; Anders Grennberg; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; optimal detection; transient signals; noncoherent detection; unknown arrival time; ultrasonic nondestructive testing; nonlinear sensor; stochastic resonance; Signalbehandling; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling; Signal Processing; signalbehandling;

    Sammanfattning : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. LÄS MER

  2. 2. Studies of water vapor transport and sorption in wood

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Lars Wadsö; [1993]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaluation; measurements; non-Fickian behavior; absorption; sorption method; transient; unsteady-state; wood; sorption; surface mass transfer coefficient; water vapor; error analysis;

    Sammanfattning : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. LÄS MER

  3. 3. Diagnosing burn-out: An Anthropological Study of a Social Concept in Sweden

    Detta är en avhandling från Social Anthropology

    Författare :Torbjörn Friberg; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; företagssociologi; Arbetslivssociologi; sociology of enterprise; Sociology of labour; Sociologi; Sociology; Unhappy person; Transient phenomenon; Anthropology at home; Social problems and welfare; national insurance; Sociala problem; social välfärd; socialförsäkring; Cultural anthropology; ethnology; Kulturantropologi; etnologi;

    Sammanfattning : This is a thesis about the genesis, use, and decline of burn-out as a social concept in Sweden. The burn-out concept is treated as social because its classification of people interacts with the people classified. As a consequence of this, burn-out is studied in a dynamic holistic way, as an entirely social system within Swedish society. LÄS MER

  4. 4. Transient Response of Grounding Systems Caused by Lightning: Modelling and Experiments

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Yaqing Liu; Uppsala universitet.; [2004]

  5. 5. Studies of Mechanical Properties and Intracellular Ca2+ Transients in Frog Single Muscle Fibres

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Yin-Biao Sun; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Farmakologi; toxicology; pharmacy; pharmacognosy; Pharmacological sciences; Ca2 transient; Skeletal muscle fibre; isometric contraction; intracellular calcium; crossbridge; fluo-3; frog muscle; force-velocity relation; BAPTA; skinned fibre; BDM; farmakognosi; farmaci; toxikologi; Physiology; Fysiologi;

    Sammanfattning : Intracellular Ca2+ transients, monitored by the calcium-sensitive dye, fluo-3, were studied during isometric twitches and tetani in intact single muscle fibres of the frog (sarcomere length, 2.2 mm; temperature, 2-5 or 10-12 ºC). The Ca2+ transient during twitch stimulation was very brief when compared with the isometric force. LÄS MER
