    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  3. 3. Heat Flow in Building Components, Experiment and Analysis

    Författare :Petter Wallentén; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiation exchange; longwave; shortwave; transient; frequency analysis; finite difference; measurements; wall; window; heat transfer coefficient; convective; full scale; natural climate; in situ; counter flow insulation; heat transfer; dynamic insulation; temperature; building; solar radiation; window model; Building construction; Byggnadsteknik;

    Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER

  4. 4. Transient growth of disturbances in laminar pipe flow

    Författare :Lars Bergström; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : Transient growth of disturbances is studied theoretically in pipe Poiseuille flow and experimentally both in pipe and plane Poiseuille flow. The theoretical results, based on the initial value problem, show that a large transient amplification occurs for small, angular dependent disturbances in pipe Poiseuille flow although all modes are damped.

  5. 5. Bandwidth-reduced Linear Models of Non-continuous Power System Components

    Författare :Jonas Persson; Lennart Söder; Liisa Haarla; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linearization methods; frequency analysis; transient analysis; time-domain simulations; eigenvalues; linear analysis; TCSC; Electric power engineering; Elkraftteknik;

    Sammanfattning : Denna avhandling är fokuserad på modellering av elkraftsystemkomponenter och deras representation vid simuleringar av elkraftsystem. Avhandlingen jämför olika linjäriseringstekniker. Dessa tekniker är såväl numeriska som analytiska och används vid linjärisering av ett dynamiskt system. LÄS MER
