1. 36. Styrning av tågtrafik på Malmbanan

   Författare :Kristina Nilsson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

   Sammanfattning : The single-track Swedish iron ore line Malmbanan stretches from Luleå to the Norwegian city of Narvik. The mine company LKAB transport iron ore on Malmbanan from the mines in Kiruna and Malmberget to the harbours in Narvik and Luleå for export. The daily traffic also consists of passenger trains and freight trains. LÄS MER

3. 37. An Experimental Study to Measure Grout Penetrability, Improve the Grout Spread, and Evaluate the Real Time Grouting Control Theory

   Författare :Ali Nejad Ghafar; Stefan Larsson; Almir Draganovic; Chadi El Mohtar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Due to the significant influence of the grout penetrability properties on spread of grout in rock fractures, this study aimed to investigate the grout penetrability from four different aspects. In Part (a), after review of all the existing methodologies developed to measure the grout penetrability, Filter-pump and Penetrability-meter were examined against Short-slot to figure out which one is more reliable.

5. 39. Evaluation of energy conserving measures in buildings connected to a district heating system : case studies in Gävle, Sweden

   Författare :Mattias Gustafsson; Björn Karlsson; Magnus Åberg; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energieffektivisering; miljonprogrammet; solceller;

   Sammanfattning : When different energy conserving measures are implemented for reducing energy use in buildings and the buildings are connected to district heating systems, it is important that an overall system analysis is made which takes into account the effects of total change of energy use due to the energy conserving measures.The method applied in this thesis uses hourly production data for the different production units in the district heating system in Gävle, Sweden.

7. 40. 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
