1. 11. CFD investigation of a unit cell inside a Plate Heat Exchanger

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Mattias Ly; [2023]
   Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

3. 12. Agile robotic arm for vertical applications - Evaluation, design and development

   Master-uppsats, Lunds universitet/Maskinelement

   Författare :Rasmus Gren; [2023]
   Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

   Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

4. 13. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Författare :Laura Karina Pedraza Motavita; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. LÄS MER

5. 14. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Alfred El Haddad; [2023]
   Nyckelord :Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

   Sammanfattning : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

7. 15. Educational Artificial Intelligent Chatbot:Teacher Assistant & Study Buddy

   Magister-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Dimitrios Zarris; Stergios Sozos; [2023]
   Nyckelord :chatbot; teacher assistant; study buddy; student buddy; artificial intelligence; ai; llm; gpt;

   Sammanfattning : In the rapidly evolving landscape of artificial intelligence, the potential of large language models (LLMs) remains a focal point of exploration, especially in the domain of education. This research delves into the capabilities of AI-enhanced chatbots, with a spotlight on the "Teacher Assistant" & "Study Buddy" approaches. LÄS MER
