  1. 21. Extrapolation of polynomial nets and their generalization guarantees

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

    Author : Yongtao Wu; [2022]
    Keywords : Polynomial neural networks; Neural tangent kernel; Extrapolation; Polynomial neural networks; Neural tangent kernel; Extrapolation;

    Abstract : Polynomial neural networks (NNs-Hp) have recently demonstrated high expressivity and efficiency across several tasks. However, a theoretical explanation toward such success is still unclear, especially when compared to the classical neural networks. READ MORE

  3. 22. Simulating Microwave Heating for Industrial Processes Using the Finite-Difference Time-Domain Method

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Dante Grenholm; Axel Nilsson; Linus Olofsson; Oskar Pettersson Löfstedt; [2022]
    Keywords : Microwave oven; Heating; Simulation; Mikrovågsugn; Uppvärmning; Simulering;

    Abstract : Microwave heating is an efficient way of heating compared to conventional industrial alternatives such as autoclaves, a type of pressure cooker commonly used for curing and sterilisation. One problem that limits the adoption of microwave ovens in industrial processes is uneven heating. READ MORE

  4. 23. Modelling of gene regulatory and spatial mechanisms which pattern the early human neural tube

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Fredrik Bertilsson; [2022]
    Keywords : Biophysics; systems biology; gene regulatory networks; neural tube; isthmic organizer; midbrain-hindbrain boundary; WNT; FGF; morphogens; reaction-diffusion; finite-difference; 3D modelling; Physics and Astronomy;

    Abstract : Tissue patterning during development is thought to be driven largely by gene regulatory responses to spatial gradients of molecular signals, known as morphogens. In this thesis, early patterning of the human neural tube is studied using two different gene regulatory network models. READ MORE

  5. 24. Numerical solutions to the incompressible Navier-Stokes equations : Finite difference solutions in curvilinear coordinates

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : David Niemelä; [2022]
    Keywords : ;

    Abstract : A finite difference scheme for the incompressible Navier-Stokes equations in 2-dimensionalcurvilinear coordinates is derived. The scheme uses high-order Summation-By-Parts operatorsand boundaries are handled by the Projection method. READ MORE

  6. 25. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linda Péroux; [2022]
    Keywords : Technology and Engineering;

    Abstract : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. READ MORE
