  1. 1. A quantitative analysis of plume gas distributions from different detection studies on Europa

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

    Author : Anujan Ranganathan; [2023]
    Keywords : Europa; Water; Plume distribution; Surface Density; Column Density; Total number of molecules; Europa; Vatten; Plym Distribution; Ytdensitet; Kolumndensitet; Total mängd molekyler;

    Abstract : The search for water has been vital in our solar system as water indicates a potential for life. The search has been extended to satellites orbiting the outer planets. It has already been proven that water exists on Saturn’s moon, Enceladus, where the spacecraft Cassini did a flyby through a water plume. READ MORE

  3. 2. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels

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

    Author : Prasetyo Putranto; [2023]
    Keywords : Channel aging; Pilot spacing; Rayleigh; Rician; Spectral efficiency; Uncrewed aerial vehicles; Kanalåldring; Pilotavstånd; Rayleigh; Rician; Spectral effektivitet; Obemannade flygfordon;

    Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE

  4. 3. Cytokine capture with beads in cytotoxicity assays in microwells

    University essay from KTH/Tillämpad fysik

    Author : Maxime Simon; [2023]
    Keywords : Microbead; Inteferon gamma; Natural Killer cells; microwell; binding-reaction model; Mikrokula; Interferon gamma; Naturliga Mördarceller; Mikrobrunn; modell för bindningsreaktion;

    Abstract : Cytokines are small, secreted proteins that are important for cell signalling in theimmune system. Interferon gamma (IFN-γ) is one of the most potent cytokines thatnatural killer (NK) cells of the innate immune system secrete with both antiviral,antibacterial, and antitumoral activity. READ MORE

  5. 4. Electromagnetic Heating of Coated Ellipsoidal Gold Nanoparticles in Biological Tissue at Radio Frequencies

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

    Author : Olle Hennert; Robert Themptander; [2023]
    Keywords : ;

    Abstract : Radiofrequency heating of gold nanoparticles for use in remote hyperthermia cancer treatment has seenrapidly growing interest in the last decade. While most of the focus has been on studying sphericalnanoparticles, a recent report suggests ellipsoidal particles can significantly increase heat absorption. READ MORE

  6. 5. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size

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

    Author : Erik Algarp; [2022]
    Keywords : Antennaimplant; Medical Implant CommunicationSystem; Electrically small antenna; Electric dipole; Magnetic dipole; Fundamental bounds; Performance limits; Radiation efficiency; Conductor loss; Antennimplant; Medical Implant Communication System; Elektriskt små antenner; Elektrisk dipol; Magnetisk dipol; Fundamentala begränsningar; Prestandagränser; Strålningseffektivitet; Metallförlust;

    Abstract : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants. READ MORE
