1. 1. Satellite signal attenuation due to atmospheric influences in northern Sweden

   University essay from Umeå universitet/Institutionen för fysik

   Author : Adrian Stigsson; [2024]
   Keywords : ;

   Abstract : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. READ MORE

3. 2. Creating a semantic segmentationmachine learning model for sea icedetection on radar images to study theThwaites region

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Carmen Fuentes Soria; [2022]
   Keywords : Synthetic Aperture Radar SAR ; Machine Learning ML ; Semantic segmentation; Convolutional Neural Networks CNN ; Thwaites Glacier;

   Abstract : This thesis presents a deep learning tool able to identify ice in radar images fromthe sea-ice environment of the Twhaites glacier outlet. The project is motivatedby the threatening situation of the Thwaites glacier that has been increasingits mass loss rate during the last decade. READ MORE

4. 3. Using linear regression and neural network to forecast sewer flow from X-band radar data

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Fredrik Wigertz; [2021]
   Keywords : Neural network; Linear regression; Flow forecasting; Wastewater; Wastewater treatment plant; Rainfall-runoff modelling; X-band radar; Neurala nätverk; Linjär regression; Flödesprognosering; Avloppsvatten; Reningsverk; Avrinningsmodellering; X-bandradar;

   Abstract : The climate adaptation of our cities and the optimization of our technical systems with regards to weather sets high demands on the availability and the processing of weather data. The possibility to forecast disturbances of influent flow rate to wastewater treatment plants allow control systems counteract these disturbances before they have a harmful effect on the treatment processes.

5. 4. 3D-Printed Geodesic Reflective Luneburg Lens Antenna for X-Band

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

   Author : David Oxelmark; Lukas Jonasson; [2021]
   Keywords : 3D-printing; Geodesic lens; Reflective Luneburg lens; Transformation optics; Waveguide; X-band;

   Abstract : With the rise of 5G and the increasing number ofdevices, novel antenna designs are needed to meet the demandof the future. In this report, the authors present a design andexperimental verification of a 3D-printed Geodesic ModulatedReflective Luneburg lens antenna working at the X-Band, 8-12GHz. READ MORE

6. 5. Using X-band Radar with a Neural Network to Forecast Combined Sewer Flow - A case study in Lund

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Filip Faust; Per Nelsson; [2020]
   Keywords : X-band radar; neural networks; combined sewer; forecasting; urban hydrology; Lund; Technology and Engineering;

   Abstract : This study aimed to forecast combined sewer flow into a wastewater treatment plant in Lund, Sweden by using uncalibrated X-band radar data with a neural network. Neural networks have proved themselves useful in the field of forecasting as they can solve multiple kinds of problems and recognise patterns in the data (Alemu et al. READ MORE
