  1. 16. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

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

    Author : Henrik Åkerberg; [2023]
    Keywords : Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

    Abstract : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. READ MORE

  3. 17. Filtering aspects

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Johannes Pape; [2023]
    Keywords : ;

    Abstract : In this report, a Fourier spectral approximation of the solution to the linear convection--diffusion equation for initial conditions of different smoothness, and for Burger's equation for the initial condition f(x) = sin(x), was constructed, and implemented. Three different filters (Cesàro, Lanczos, and 4--th order exponential cutoff) were either applied to the initial condition or to the numerical approximation after the last integration step has been performed.

  4. 18. Lignin in Cosmetics: State of the Art : Discerning the value of lignin in the cosmetic industry

    University essay from Uppsala universitet/Industriell teknik; Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Nellie Henriksson; Klas Nordell; [2023]
    Keywords : Lignin; Cosmetics; Personal care; Innovation; Cosmetic industry; Functional materials. Biotechnology; functional materials; green chemistry; Lignin; kosmetik; kosmetikaindustrin; Bioteknik; Nanomaterial; SPF; UV;

    Abstract : This study was carried out at the Department of Nanotechnology and Functional Materials,Uppsala University, one of several places where the interest of lignin in cosmetics is constantly growing. The functionalities of lignin have been studied to a great extent revealing its potential as a natural biopolymer to serve as a replacement for environmentally hazardous components in cosmetic formulations, namely UV-filters in sunscreens.

  5. 19. Accumulation of 63Ni, 106Ru and 125Sb in phytoplankton

    University essay from

    Author : Yusuf Ali; [2022-08-22]
    Keywords : Medical physics; Environmental radiology; Nuclear Power Plants; concentration factor CF ; phytoplankton; phaeodactylum tricornutum; radioactive releases; nickel; ruthenium; antimony; gamma spectroscopy; liquid scintillation counting;

    Abstract : Background: Nuclear Power Plants (NPPs) release small amounts of radionuclides which contribute with a low radiation dose to the environment as well as humans and animals. In this context, marine ecosystems are critical, since most NPPs in Sweden are located by the sea. READ MORE

  6. 20. Evaluation of deep learning image reconstruction for brain- and abdominal CT - A visual grading characteristics study

    University essay from

    Author : Tuva Skarp; [2022-05-04]
    Keywords : Medical physics; CT; Computed tomography; imaging; Deep learning image reconstruction;

    Abstract : Computed tomography (CT) is a common medical imaging method today. There are different ways of reconstructing the images from a CT examination. The standard method is the filtered back projection (FBP). READ MORE
