1. 16. Multivariate Time Series Forecasting in MAX IV Electron Accelerator using Predictive Maintenance

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Henrik Heinze; Olof Persson; [2022]
   Keywords : ;

   Abstract : There are different approaches to take when it comes to maintenance of certaine quipment in environments such as production factories, manufacturing facilities and research laboratories. No type of equipment that falls in any of these categories are perfect and lack the requirement of preservation in some form. READ MORE

3. 17. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Claudia Bartos; [2022]
   Keywords : ATP bioluminescense; redox potential; bacillus; board production;

   Abstract : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants.

4. 18. Using machine learning and multivariate predictive modelling to shorten dissolution time for solid dosage with the fully automated dissolution robot SingBATH

   University essay from KTH/Fiber- och polymerteknologi

   Author : George Mado; [2021]
   Keywords : Prediction; multivariate; dissolution; SIMCA; SingBATH; Prediktion; multivariat; frisättning; SIMCA; SingBATH;

   Abstract : Syftet med detta examensarbete är att förkorta 20-timmars frisättningen för en tablettformulering med förlängd frisättning genom att använda maskininlärning genom multivariat prediktiv modellering, helt automatisera frisättningsmetoden och utvärdera antalet tabletter som kan representera en batch vid frisättningsanalys av en specifik provtablett. Prediktionsmodellerna byggdes i SIMCA 14, som är en programvara för multivariat dataanalys. READ MORE

5. 19. Neural Ordinary Differential Equations for Anomaly Detection

   University essay from KTH/Matematisk statistik

   Author : Jón Hlöðver Friðriksson; Erik Ågren; [2021]
   Keywords : Anomaly detection; Neural ordinary differential equations; Statistical modelling; Autoregression; Variational autoencoder; Multivariate time series; Anomalidetektion; Neurala ordinära differentialekvationer; Statistisk modellering; Autoregression; Variational autoencoder; Multivariat tidsserie;

   Abstract : Today, a large amount of time series data is being produced from a variety of different devices such as smart speakers, cell phones and vehicles. This data can be used to make inferences and predictions. Neural network based methods are among one of the most popular ways to model time series data. READ MORE

6. 20. Real-time Classification of Multi-sensor Signals with Subtle Disturbances Using Machine Learning : A threaded fastening assembly case study

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