1. 21. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Hoda Mahmoodi; [2023]
   Nyckelord :Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

   Sammanfattning : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. LÄS MER

3. 22. Controls over stream temperature in a northern boreal landscape

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Oskar Damström; [2023]
   Nyckelord :Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

   Sammanfattning : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. LÄS MER

   Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

5. 24. AI-assisted analysis of ICT-centre cooling : Using K-means clustering to identify cooling patterns in water-cooled ICT rooms

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Oliver Wallin; Johan Jigsved; [2023]
   Nyckelord :AI; K-means; clustering; ICT-centre; data centre; data center; ICT-center; cooling; data center cooling;

   Sammanfattning : Information and communications technology (ICT) is an important part in today’s society and around 60% of the world's population are connected to the internet. Processing and storing ICT data corresponds to approximately 1% of the global electricity demand. LÄS MER

7. 25. Kartläggning & optimering av externa flöden ur ett hållbarhetsperspektiv : En fallstudie på Gestamp HardTech

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Malin Norgren; Elin Lindberg; [2023]
   Nyckelord :Sustainable transport; Vehicle emissions modeling; Truck emissions; Vessel emissions; Train emissions; Air pollution modeling; Future vehicles;

   Sammanfattning : In the pursuit of sustainable development, the transportation sector plays a crucial role by significantly contributing to greenhouse gas emissions. The purpose of this study is to examine how companies utilizing third-party logistics can compile and reduce transport-related emissions, more specifically investigating short- and long-term opportunities for the external flow of Gestamp HardTech in Luleå.
