  1. 1. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

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

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  3. 2. Promoting a better public health quality with urban green space in an informal settlement, Bogota, Colombia

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Pamela Okinedo; [2022]
    Keywords : public spaces; urban green spaces; climate change; air pollution; informal settlements; ecosystem services;

    Abstract : Heat waves, rising temperatures, air pollution, and loss of biodiversity are examples of issues that will and are already rising due to climate change. The urban environment is one that continues to steadily grow at the cost of natural vegetation in the city, and this will only worsen with population growth. READ MORE

  4. 3. Pulse Repetition Interval Time Series Modeling for Radar Waves using Long Short-Term Memory Artificial Recurrent Neural Networks

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Adam Lindell; [2019]
    Keywords : ;

    Abstract : This project is a performance study of Long Short-Term Memory artificial neural networks in the context of a specific time series prediction problem consisting of radar pulse trains. The network is tested both in terms of accuracy on a regular time series but also on an incomplete time series where values have been removed in order to test its robustness/resistance to small errors.

  5. 4. A detailed study of auroral fragments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Joshua Dreyer; [2019]
    Keywords : aurora; fragments; Svalbard; all-sky camera; MSP; ASK; EISCAT;

    Abstract : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.

  6. 5. Efficient seakeeping performance predictions with CFD

    University essay from KTH/Marina system

    Author : Benjamin Lagemann; [2019]
    Keywords : added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

    Abstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE
