  1. 1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Lisa Linard Pedersen; [2024]
    Keywords : Technology and Engineering;

    Abstract : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. READ MORE

  3. 2. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Emma Dahlstedt; [2023-08-18]
    Keywords : Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Abstract : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. READ MORE

  4. 3. Påverkan av tid och temperatur vid analys av pH i träckprov från häst

    University essay from SLU/Dept. of Clinical Sciences

    Author : Olivia Ahlstedt; Martina Löfgren; [2023]
    Keywords : ekvint; fecesprov; mag-tarmhälsa; metodstudie; pH; provförvaring; provhantering;

    Abstract : Mätning av pH i träck är vanligt förekommande i vetenskapliga artiklar om nutrition och magtarmhälsa på häst. Metoderna för mätning av fekalt pH som beskrivs i litteraturen varierar mellan olika studier vilket gör att det finns en efterfrågan av ett mer standardiserat protokoll för mätning av fekalt pH.

  5. 4. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Dolev Illouz; [2023]
    Keywords : super-resolution; alternating descent conditional gradient method; ADCG; multiple-emitter localization; nanoscale imaging; single molecule tracking; Physics and Astronomy;

    Abstract : This thesis examines the state-of-the-art 2D super-resolution technique alternating descent conditional gradient (ADCG) method's ability to accurately localize fluorophores in diffraction-limited single molecule images (SMI) and analyze the impact of pre-processing and post-processing modules on ADCG's fluorophore localization. A synthetic dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their noise parameters.

  6. 5. Combustibility study of resin for warm magnet coils used at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Juan Carlos Lopez Santiago; [2023]
    Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE
