  1. 1. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mhd Osman Bernieh; [2023]
    Nyckelord :Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Sammanfattning : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. LÄS MER

  3. 2. Chemoreception of a Two-Dimensional Cell with Multilayer Diffusion

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Steffi Schijf; [2023]
    Nyckelord :biophysics; chemoreception; receptors; multilayer diffusion; diffusion; Physics and Astronomy;

    Sammanfattning : Previously, Berg and Purcell found an expression for the diffusion current of particles into a set of receptors in their paper Physics of Chemoreception. These receptors were assumed to be uniformly distributed on a spherical cell's surface and the receptors where idealized as circular patches. LÄS MER

  4. 3. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Mika Persson; [2022]
    Nyckelord :Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Sammanfattning : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

  5. 4. Ta hand om dig. /red, Krisinfo

    Kandidat-uppsats, Lunds universitet/Institutionen för strategisk kommunikation

    Författare :Maja Persson; Nanna Svensson; [2022]
    Nyckelord :Krisinformation.se; trust; engagement; content moderation; moderation strategies; crisis communication; social media; SCCT; rhetorical strategies; stylistic device; symbols; signal theory; Covid-19; tillit; engagemang; innehållsmoderering; modereringsstrategier; kriskommunikation; sociala medier; retoriska strategier; stilfigurer; symboler; signalteori; Social Sciences;

    Sammanfattning : We live in a crisis society where crises are a constant in our lives, furthermore people in a crisis are searching for information and understanding through social media, where misinformation and disinformation is spread. The aim of this study was to reach an increased understanding of what purpose Krisinformation. LÄS MER

  7. 5. Advanced Detection Methods of Genomic Barcodes for Genotyping Escherichia coli Libraries

    Master-uppsats, Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Nicole Eger; [2021]
    Nyckelord :Genotyping; Genomic barcodes; LAMP; PNA; RCA; FISH;

    Sammanfattning : Pooled cell strain libraries are a powerful tool allowing to investigate the influence of genetic modifications on phenotypes in high throughput single-cell assays. To link the genotype to phenotype in each cell of the library, unique 20 base pairs (bp) long barcodes are used to allow in situ genotyping after phenotyping via fluorescence microscopy. LÄS MER
