1. 6. Dirichlet-to-Neumann maps and Nonlinear eigenvalue problems

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Tindra Jernström; Anna Öhman; [2023]
   Keywords : Dirichlet-to-Neumann maps; Nonlinear eigenvalue problems; Absorbing boundary conditions;

   Abstract : Differential equations arise frequently in modeling of physical systems, often resulting in linear eigenvalue problems. However, when dealing with large physical domains, solving such problems can be computationally expensive. READ MORE

3. 7. Football Trajectory Modeling Using Masked Autoencoders : Using Masked Autoencoder for Anomaly Detection and Correction for Football Trajectories

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

   Author : Sandra Tor; [2023]
   Keywords : Machine Learning; Autoencoders; Masked autoencoders; Time series; Trajectory modeling; Time series modeling; Anomaly detection; Anomaly correction; Football; Maskininlärning; Autoencoders; Maskerade autoencoders; Tidsserie; Banmodellering; Tidsseriemodellering; Avvikelsedetektering; Avvikelsekorrigering; Fotboll;

   Abstract : Football trajectory modeling is a powerful tool for predicting and evaluating the movement of a football and its dynamics. Masked autoencoders are scalable self-supervised learners used for representation learning of partially observable data. READ MORE

4. 8. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

5. 9. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Sanger Shinwari; [2023]
   Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

   Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

6. 10. Implementing SAE Techniques to Predict Global Spectacles Needs

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Yuxue Zhang; [2023]
   Keywords : small area estimation; area-level model; empirical best linear unbiased prediction EBLUP ; generalized linear mixed models; Conditional Autoregressive; spatial correlation; spectacle needs; assistive products; auxiliary data; hglm; relative standard error; simulation;

   Abstract : This study delves into the application of Small Area Estimation (SAE) techniques to enhance the accuracy of predicting global needs for assistive spectacles. By leveraging the power of SAE, the research undertakes a comprehensive exploration, employing arange of predictive models including Linear Regression (LR), Empirical Best Linear Unbiased Prediction (EBLUP), hglm (from R package) with Conditional Autoregressive (CAR), and Generalized Linear Mixed Models (GLMM).
