1. 11. Analysis of pervasive climate risks to global rice production at the subnational level

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Qian Mei; [2023]
   Keywords : ;

   Abstract : Rice is a vital crop and main source of calories for half the global population, particularly in the GlobalSouth. Despite increasing demand for rice, climate change, urbanisation, and land use development arethreatening rice production and therefore food security. READ MORE

3. 12. Content Based Video Encoding Based on Spatial and TemporalInformation

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Theofanis Papakonstantinou; [2023]
   Keywords : ;

   Abstract : A significant amount of video content is produced today that needs to be stored, distributed, andstreamed globally in a cost-effective way. This relies on video compression, a process performedby encoding software that remove spatial redundancy, the similarities within a frame, andtemporal redundancy, the similarities between temporarily adjacent frames.

4. 13. Development of a DEM-FEM framework for infrastructure simulations

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Anita Ullrich; [2022-09-20]
   Keywords : ;

   Abstract : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. READ MORE

5. 14. Insurance Fraud Detection using Unsupervised Sequential Anomaly Detection

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Anton Hansson; Hugo Cedervall; [2022]
   Keywords : Insurance Fraud Detection; Anomaly Detection; Long Short-Term Memory Networks LSTM ; Unsupervised Learning; Autoencoder AE ; Variational Autoencoder VAE ; Interpretable Machine Learning; Feature Engineering; Feature Selection; Feature Importance;

   Abstract : Fraud is a common crime within the insurance industry, and insurance companies want to quickly identify fraudulent claimants as they often result in higher premiums for honest customers. Due to the digital transformation where the sheer volume and complexity of available data has grown, manual fraud detection is no longer suitable. READ MORE

6. 15. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fanny Jeppsson Stahl; [2022]
   Keywords : Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

   Abstract : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.
