1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Fawzi Kayali; [2023]
   Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

3. 2. Techno-economic analysis and simulation of low temperature district heating networks

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Ilia Iarkov; [2023]
   Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

4. 3. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :William Gulding; [2023]
   Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

   Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

5. 4. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
   Nyckelord :Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

   Sammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER

7. 5. CatFish Project - Autonomy : Control System, Object Detection and Tracking for USVs

   Master-uppsats,

   Författare :Michael Alexander Georg Forschlé; [2022]
   Nyckelord :;

   Sammanfattning : As a student project at Halmstad University, CatFish aims to make water quality measurement easier by the development of a set of cooperating measurement drones in and under water and up in the air. To minimize human effort during the operation of the CatFish system, the drones shall act autonomously to reach given sets of target coordinates on their own to fulfill desired measurement tasks on arrival.
