1. 1. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Ivan Ruzic; [2023-06-21]
   Nyckelord :heat wave; urban trees; NDVI; remote sensing;

   Sammanfattning : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. LÄS MER

3. 2. Energy retrofitting effect on perceived indoor climate: A case study of Estonian multi-family buildings

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

   Författare :Kadri Reinumägi; [2023]
   Nyckelord :Indoor environment; Thermal comfort; Indoor Air Quality; Window airing habits; Energy renovation; Occupant survey; Technology and Engineering;

   Sammanfattning : Energy renovations are an important measure for achieving the European Union’s target of climate neutrality by 2050. To meet the EU goal, Estonia needs to fully renovate 14 000 multi-family buildings by that time, affecting the indoor environment conditions of a large number of people. LÄS MER

4. 3. Methodology for Designing Bespoke Air Handling Units

   Master-uppsats, KTH/Energiteknik

   Författare :Alexandra Malysheva; [2023]

5. 4. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Therese Bäckström; [2023]
   Nyckelord :Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

   Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER

7. 5. Automated High-Temperature Pressure Sensor Verification and Characterization

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Algirdas Bartkevicius; [2023]
   Nyckelord :Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

   Sammanfattning : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. LÄS MER
