  1. 6. Bladder Monitoring Using Ultra-Wideband Radar and Vivaldi Antenna

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Erica Jonsson; Attila Kovács; [2023]
    Keywords : UWB; Ultra-wideband; Vivaldi antenna; Bladder monitoring; Radar; Radar design; Ultra-wideband radar;

    Abstract : Millions worldwide cannot tell when their bladder is nearing total capacity. The catheter, a tube to empty the bladder, is a vital part of life for many people. A catheter is, however, not a comfortable option, and it is the most common cause of infection in people staying in hospitals. READ MORE

  3. 7. Virtual alignment of real-world objects

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Tommy Ekberg; William Ekelund; [2023]
    Keywords : Ultra-wideband; Indoor positioning system; Document survey; NLoS; Multisensor; Trilateration; Localization;

    Abstract : High accuracy localization of objects is a crucial function for many modern applications, such as virtual and augmented reality, robotics, and self-driving cars, among others. This requires determining precise location of objects indoors, which is a challenging task. READ MORE

  4. 8. Estimating Relative Position and Orientation Based on UWB-IMU Fusion for Fixed Wing UAVs

    University essay from Linköpings universitet/Reglerteknik

    Author : Daniel Sandvall; Eric Sevonius; [2023]
    Keywords : UWB; Relative positioning; Sensor fusion; UAV; Formation flight; Fixed wing; Relative localization; EKF; FGO;

    Abstract : In recent years, the interest in flying multiple Unmanned Aerial Vehicles (UAVs) in formation has increased. One challenging aspect of achieving this is the relative positioning within the swarm. READ MORE

  5. 9. Portable HF Antennas for Concurrent Multiband Systems

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

    Author : Sambhav Malhotra; [2022]
    Keywords : Antenna; HF; Skywave Propogation; Multiband;

    Abstract : Current HF communication systems are confined to transmit in relatively narrow frequency band of a few 100 kHz at the time. The problems with limited bandwidth accumulate in HF-networks with multiple links and such networks are therefore hardly “internet capable” today. READ MORE

  6. 10. Homomorphic Encryption for Audio Conferencing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Herman Nordin; Ebba Lindström; [2022]
    Keywords : Homomorphic encryption; VoIP; security; audio conferencing; cryptography;

    Abstract : Homomorphic encryption (HE) enables computations on encrypted data making it possible to perform calculations on a server without sharing the secret key for decryption. HE is relatively new and has seen significant improvements in recent years in terms of speed of encryption, decryption, operations, and the number of operations possible to perform in a row without damaging the ciphertext.
