  1. 1. Finite Difference Approximations for Wave Propagation

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Sebastian Lindqvist; [2022]
    Keywords : Finite Difference; Maxwell’s equations; wave propagation; advection equation; partial differential equations;

    Abstract : Finite difference approximations are methods for solving differential equations by approximating derivatives. This work will begin with how to solve a partial differential equation (PDE) called the advection equation, ut + cux = 0. READ MORE

  4. 3. Anomaly detection in 5G beam propagation

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

    Author : Katarina Hellgren; Phiphi Tran; [2021]
    Keywords : Machine learning; wireless communication; 5G; beam propagation; DBSCAN; KNN; anomaly detection; clustering; Technology and Engineering;

    Abstract : Advancements in today's technology has motivated invention of faster mobile communication systems. The fifth generation mobile network, 5G, is the latest version made by the third generation partnership project (3GPP) and expects to both increase connection speed and reduce latency, which eventually will make it applicable in supporting state-of-the art technologies such as virtual reality and self-driving vehicles among others.

  5. 4. Lean Beam Management for New Radio

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

    Author : Nawanit Kumar; [2020]
    Keywords : 5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Abstract : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. READ MORE

  6. 5. Denoising Monte Carlo Dose Calculations Using a Deep Neural Network

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

    Author : Hannes Fornander; [2019]
    Keywords : ;

    Abstract : This thesis explores the possibility of using a deep neural network (DNN) to denoise Monte Carlo dose calculations for external beam radiotherapy. The dose distributions considered here are for inhomogeneous materials such as those of the human body. READ MORE
