1. 1. Optimal control of clarifier-thickeners

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

   Författare :Sakari Teerikoski; [2017]
   Nyckelord :clarifier; thickener; modelling; simulation; control; cascade control; settling;

   Sammanfattning : A computer model for a general clarifier-thickener has been made and used for comparing different strategies for control of such dewatering units through simulations. The model builds on widely acknowledged theory for modelling clarifier-thickeners - discretizing the settling PDE into a set of ODEs so that concentrations of solids at discrete depths inside the unit become the states of the numerical model - and it was written in the Modelica language using the modelling and simulation environment Dymola.

3. 2. A prototype backscattering neutron time-of-flight spectrometer

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Sakari Teerikoski; [2015]
   Nyckelord :;

   Sammanfattning : Measuring neutron energies is an essential task in fusion research. The time-of-flight (TOF) of neutrons moving a known distance can be used to determine these energies. Slower neutrons have longer TOFs for fix flight paths. Neutrons are slowed down when they backscatter. LÄS MER
