3. 42. A mechanical model of an axial piston machine

   Författare :Rasmus Löfstrand Grip; Ulf Sellgren; Niclas Strömberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-body mechanical model; axial piston; Z-shaft; wobble plate; Sophia; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : A mechanical model of an axial piston-type machine with a so-called wobble plate and Z-shaft mechanism is presented. The overall aim is to design and construct an oil-free piston expander demonstrator as a first step to realizing an advanced and compact small-scale steam engine system. LÄS MER

4. 43. Electric Vehicle Charging Modeling

   Författare :Pia Grahn; Lennart Söder; Ola Carlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With an electrified passenger transportation fleet, carbon dioxide emissions could be reduced significantly depending on the electric power production mix. Increased electric power consumption due to electric vehicle charging demands of electric vehicle fleets may be met by increased amount of renewable power production in the electrical systems.

5. 44. The impact of wind power variability on the least-cost dispatch of units in the electricity generation system

   Författare :Lisa Göransson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; intermittency; wind-thermal system; variability; cycling costs; electricity generation system; dispatch modeling; variation management;

   Sammanfattning : This thesis investigates the dynamics of electricity generation systems that involve high levels of wind power. Methods to account for wind power variability in electricity-dispatch models are explored, and the impact of wind power variability on the optimal output of the generation units, so as to meet the system load with the lowest possible cost (economic dispatch), is analyzed for several systems, for both regional and European cases.

7. 45. Loss Minimisation in Dynamic Food Processes

   Författare :Marcus Henningsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

   Sammanfattning : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. LÄS MER
