1. 1. Studies on the application of gas cooling as used by firefighters

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jan Bonnier; [2017]
   Nyckelord :Gas cooling; Firefighting; Fire Service; 3D-technique; Technology and Engineering;

   Sammanfattning : Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. LÄS MER

3. 2. Geogrids in cold climate : Temperature controlled tensile tests & Half-scale installation tests at different temperatures 

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Björn Bonthron; Christian Jonsson; [2017]
   Nyckelord :geogrid; cold climate; low temperature; tensile test; half-scale test;

   Sammanfattning : Due to the findings of extensive damage on geogrids used in a road embankment in northern Sweden, the Swedish Transport Administration (TRV) started to investigate the reason of these damages. Since the geogrids were installed at low temperature, below 0°C, it was suspected that the damages were connected the low temperature. LÄS MER

4. 3. Project Solaris – Construction of Solar Powered UAV Prototype

   M1-uppsats, Akademin för innovation, design och teknik

   Författare :Magnus Johansson; [2011]
   Nyckelord :Flight testing; empennage; solaris; differentiated thrust;

   Sammanfattning : Abstract To control an un-swept flying wing is problematic in some ways. One of the problems is that when the wing experiences a disturbance in yaw, it does not, since it has no tail, generate any torque in the opposite direction as a plane with a vertical stabilizer does.
