3. 17. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sara Rosendahl; [2021]
   Keywords : Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

   Abstract : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. READ MORE

4. 18. Effective machine learning techniques for detecting inflow and infiltration water in wastewater channels

   University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

   Author : Jonas Johansson; Viktor Westlund; [2021]
   Keywords : Inflow; infiltration; machine learning; sensor network; wastewater channels;

   Abstract : In this degree thesis, the research team analyses different ways of monitoring water flow in wastewater channels finds an effective way of processing data using machine learning on collected data from a specific area and sets up a system for finding correlations between rain levels, water usages and wastewater flow to detect infiltrations and inflow water in wastewater channels. The study concludes that a sensor network is most suited for monitoring wastewater channels and that machine learning could be used to detect infiltration and inflow water using different types of data.

5. 19. Mapping an Auditory Scene Using Eye Tracking Glasses

   University essay from Linköpings universitet/Reglerteknik

   Author : Alfred Fredriksson; Joakim Wallin; [2020]
   Keywords : Sensor Fusion;

   Abstract : The cocktail party problem introduced in 1953 describes the ability to focus auditory attention in a noisy environment epitomised by a cocktail party. An individual with normal hearing uses several cues to unmask talkers of interest, such cues often lacks for people with hearing loss. READ MORE

6. 20. Högfrekventa mätningar med sensorer för transportberäkning av totalfosfor i vattendrag

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Nora Ottander; [2020]
   Keywords : turbiditet; fosfor; sensor; transportberäkning; övergödning;

   Abstract : Large areas in the Baltic Sea suffer from eutrophication, due to excessive input of nutrients, mostly nitrogen and phosphorus, from surrounding coasts. The transfer of phosphorus is mostly riverine. READ MORE
