  1. 11. Chemoreception of a Two-Dimensional Cell with Multilayer Diffusion

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

    Author : Steffi Schijf; [2023]
    Keywords : biophysics; chemoreception; receptors; multilayer diffusion; diffusion; Physics and Astronomy;

    Abstract : 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. READ MORE

  3. 12. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

    University essay from KTH/Tillämpad fysik

    Author : Elaheh Aghajafari; [2023]
    Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

    Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

  4. 13. Optimizing Consensus Protocols with Machine Learning Models : A cache-based approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kun Wu; [2023]
    Keywords : Distributed Systems; Consensus Algorithms; Machine Learning; Caching; Distribuerade system; Konsensusalgoritmer; Maskininlärning; Cachning;

    Abstract : Distributed systems offer a reliable and scalable solution for tackling massive and complex tasks that cannot be handled by a single computer. However, standard consensus protocols used in such systems often replicate data without considering the workload, leading to unnecessary retransmissions. READ MORE

  5. 14. Suspensions of Calcium Phosphate : Interactions of milk proteins to hydroxyapatite

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ying Chen; [2023]
    Keywords : Calcium fortification; Milk proteins interactions; Colloid chemistry; Food technology; engineering and nutrition; Agriculture and Food Sciences;

    Abstract : Capolac is a product containing hydroxyapatite (HA) from Arla Food Ingredients, to be used for calcium fortification. The adsorption of casein and whey proteins onto the Capolac was investigated, aiming to solve the sedimentation problem of this insoluble calcium phosphate. READ MORE

  6. 15. Simulation of Quantum Cascade Lasers

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE
