1. 26. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

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

   Author : Marie-Ange Stefanos; [2023]
   Keywords : Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

   Abstract : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

3. 27. Regression and time estimation in the manufacturing industry

   University essay from Uppsala universitet/Statistik, AI och data science

   Author : Walter Bjernulf; [2023]
   Keywords : regression; linear regression; regression trees; random forests; cross validation; variable selection; conformal prediction;

   Abstract : In this thesis an analysis is performed on operation times for different sized products in a manufacturing company. The thesis will introduce and summarise most of the theory needed to perform regression and also cover a worked example where three different regression models are learned, evaluated and analysed.

4. 28. Uncertainty Estimation in Radiation Dose Prediction U-Net

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

   Author : Frida Skarf; [2023]
   Keywords : Radiation dose prediction models; U-net; quantile regression; Monte Carlo Dropout; epistemic uncertainty estimation; aleatoric uncertainty estimation; Stråldospredicerande modeller; U-net; kvantilregression; Monte Carlo Dropout; epistemisk osäkerhetsskattning; aletorisk osäkerhetsskattning;

   Abstract : The ability to quantify uncertainties associated with neural network predictions is crucial when they are relied upon in decision-making processes, especially in safety-critical applications like radiation therapy. In this paper, a single-model estimator of both epistemic and aleatoric uncertainties in a regression 3D U-net used for radiation dose prediction is presented. READ MORE

5. 29. Failure Probability and Lifetime Estimation for Industrial Robots : A Logistic Regression and Lifetime Analysis Approach

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Erik Fahlbeck Carlsson; Martin Herbert; [2023]
   Keywords : Lifetime Analysis; Logistic regression; Prediction; Lifetime estimation; Industrial robots; Livslängdsanalys; Logistisk regression; Prediktion; Livslängdsestimering; Industriella robotar;

   Abstract : The ability to handle and process data for information extraction is getting more and more important. Using extracted data from the business to improve productivity is seen as an important part in developing the business processes. In this thesis, industrial robots and their survival times are analyzed. READ MORE

6. 30. Estimating Photovoltaic capacity using customs data : Model development of the tool NJORD and photovoltaics' characterization and impact on the African continent

   University essay from Uppsala universitet/Byggteknik och byggd miljö

   Author : Albin Åbrink; [2023]
   Keywords : Photovoltaic; Trade analysis; Development Goals; Africa;

   Abstract : Photovoltaics (PV) is one of the fastest growing power sources in the world in the last twenty years, being the most installed power source in almost half of the world's countries in 2020. Despite this, precise tracking of installations of PV does not exist in most of the world's markets due to PVs unique scalability and modularity. READ MORE
