  1. 1. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

  3. 2. On the Interaction Between Electromagnetic, Gravitational, and Plasma Related Perturbations on LRS Class II Spacetimes

    University essay from Umeå universitet/Institutionen för fysik

    Author : Philip Semrén; [2021]
    Keywords : ;

    Abstract : In this thesis, we investigate the interaction between electromagnetic, gravitational, and plasma related perturbations on homogeneous and hypersurface orthogonal Locally Rotationally Symmetric (LRS) class II spacetimes. By using these spacetimes, which allow for the inclusion of a non-zero magnetic field, as backgrounds in a perturbative approach, we are able to see interactions between the electromagnetic and gravitational variables already to first order in the perturbations.

  4. 3. Sensor concepts for Industry 4.0

    University essay from Lunds universitet/Industriell Produktion

    Author : Daniel Le; [2021]
    Keywords : Fluorescence; alumina; ruby; piezo-spectroscopic effect; Technology and Engineering;

    Abstract : The next industrial revolution has been denoted by Industry 4.0 and is the continuation of the process of knowledge acquisition and further control over the entire production process which has been evolving since the beginning of the industrialization. A paramount driver of Industry 4.0 is the smart sensor. READ MORE

  5. 4. Stability testing of all-trans-retinol in an experimental cosmetic formulation and in methanol and methanol containing butylhydroxytoluene (BHT) using reversed-phase HPLC

    University essay from KTH/Kemi

    Author : Ena Iglebaek Herceglija; [2021]
    Keywords : retinol; vitamin A; stability; antioxidant; cosmetic formulation; retinol; vitamin A; stabilitetstestning; antioxidant; kosmetika;

    Abstract : All-trans-retinol (vitamin A) används ofta som en aktiv ingrediens i kosmetiska produkter på grund av dess kliniskt validerade anti-age-egenskaper. Däremot är användningen av all-trans-retinol i kosmetiska formuleringar begränsad till följd av den kemiska stabiliteten av all-trans-retinol som påverkas av värme, syre, ljus och syror. READ MORE

  6. 5. Measuring resistivity in a contactless fashion

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Jim Klintrup; [2020]
    Keywords : resistivity; magnetic; field; diffusive; eddy; current; coils; Physics and Astronomy;

    Abstract : The aim of this thesis work was to develop a rig to measure the resistivity of a metal sample. The initial testing of the rig would be done at room temperature and calibration of the setup would be done with aluminum samples and then metallic alloys would be studied. READ MORE
