  5. 4. Beam-steered Modulation in Advanced Antenna System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Smitha Jinnahalli Venugopal; [2023]
    Keywords : 5G-MIMO; Beam-forming; Beam-steering; Advanced antenna systems; Technology and Engineering;

    Abstract : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. READ MORE

  6. 5. Permeation studies of Niacinamide and its effect on human skin

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Andebrhan Fsahaye; [2023]
    Keywords : niacinamide; permeation; human skin; impedance; hydration;

    Abstract :  Background: Niacinamide (NIA) is one of the most commonly used cosmetic ingredients. It belongs to the vitamin-B3 family and has extensive dermatological therapeutic benefits. NIA has been proven to be a useful skincare product in serving as anti-acne agent, preventing skin hyperpigmentation, removal of wrinkles from the face etc. READ MORE
