1. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER
2. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER
3. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system
Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER
4. The Heat reducing Effects of Reflective Clothing in Firefighting : A study on the efficiency of reflective textiles in personal protective equipment
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Modern firefighter protective equipment is excellent at protecting firefighters from surrounding heat, but how effective is at deflecting incoming radiant heat, and would the use of more reflective textiles, be able to further increase the equipment’s protective properties? This study aims to understand the different properties that reflective materials, compared to standard firefighter outer layers, have against radiative heat flux. The textiles of firefighter turnout gear and the reflective textiles used in the smelting industry have been examined when exposed to varying levels of radiant heat in a cone calorimeter. LÄS MER
5. Investigating the use of radiative heat panels to enhance perceived threat of fire in VR
Kandidat-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The purpose of this report was to develop and evaluate new solutions to improve the perception of fire threat in virtual reality experiments. Thermal heat have been identified as a stimulus that modern day virtual reality experiments don’t take into account that would likely affect a person in a real life fire evacuation scenario. LÄS MER
