1. 1. Fundamental aspects of HiPIMS under industrial conditions

   Författare :Mattias Samuelsson; Ulf Helmersson; Torbjörn Joelsson; Hans Högberg; Bengt Wälivaara; Jörg Patscheider; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Fundamental aspects of the high power impulse magnetron sputtering (HiPIMS) process and its implication for film growth under industrial conditions have been studied. The emerging HiPIMS technique exhibits a higher plasma density and an enhanced degree of ionisation of sputtered material as compared to conventional direct current magnetron sputtering (DCMS).

3. 2. Fault detection in water resource recovery facilities

   Författare :Oscar Samuelsson; Bengt Carlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Reliable sensor values are important for resource-efficient control and operations of wastewater treatment processes. Automatic fault detection methods are necessary to monitor the increasing amount of data produced in any modern water resource recovery facility (WRRF). LÄS MER

4. 3. Sensor Fault Detection and Process Monitoring in Water Resource Recovery Facilities

   Författare :Oscar Samuelsson; Bengt Carlsson; Elling W. Jacobsen; Uppsala universitet; []
   Nyckelord :Aeration efficiency; anomaly detection; ammonium feedback control; change detection; covariance matrix; diffuser fouling; experimental design; Gaussian process regression; novelty detection; wastewater treatment;

   Sammanfattning : Water resource recovery facilities (WRRFs) operate 24/7 to reduce the environmental impact from wastewater on receiving waters. Inaccurate measurements hinder the improvement of operations, limits the performance of automatic control, and deteriorate data quality for decision support and other purposes. LÄS MER

5. 4. Modelling and control of activated sludge processes with nitrogen removal

   Författare :Pär Samuelsson; Bengt Carlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

   Sammanfattning : Stricter legislations on nitrogen removal together with increasing wastewater loads have successively increased the need for optimization and control of activated sludge processes. The aim of this thesis is primarily to propose and illustrate methods for modelling and control of activated sludge processes, and thus possibly improve process efficiency. LÄS MER

7. 5. Methods for the Synthesis of PET Tracers and NMR Studies of Ribonuclease A

   Författare :Linda Samuelsson; Bengt Långström; Sharon Stone-Elander; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; [11C]methyl iodide; Stille reaction; palladium; Ribonuclease A; osmolytes; PFG-NMR; Organisk kemi; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis contains two parts.In the first part, general and versatile palladium-mediated 11C-C bond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. LÄS MER
