1. 1. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
   Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

   Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

3. 2. Interior Design Of Hydro-Foiling Boat

   Master-uppsats, Jönköping University/JTH, Industridesign

   Författare :Anton Nilsson; [2023]
   Nyckelord :Boat; Interior Design; Design; Hydro-Foil; Industrial Design;

   Sammanfattning : Boats have a rich history, evolving in shape and purpose. From ancient logboats to modern superyachts, their design depends on their intended use. Among personal watercraft, such as yachts and motorboats, there are various types like fishing boats and day cruisers. Runabout boats are popular today for leisure. LÄS MER

4. 3. Exploring daylight in two different hemispheres.

   Magister-uppsats, KTH/Ljusdesign

   Författare :Carolina Borgia Stagnaro; [2023]
   Nyckelord :Daylight; Climate adaptation; Regenerative evolution; Sustainable development;

   Sammanfattning : Daylight is an essential element for both the built and natural environment. A careful design that acknowledges daylight performance can improve energy efficiency and environment protection, thus making construction more sustainable. However, allocating time to deeply evaluate all the aspects in a project might be challenging. LÄS MER

5. 4. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

   Författare :Zhenyu Li; [2023]
   Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

7. 5. Modellering och Simulering av Värmehanteringssystem för Batteridrivna Elektriska Fordon (BEV)

   M1-uppsats, KTH/Produktionsutveckling

   Författare :Ismail Bajalan; Petter Nors; [2023]
   Nyckelord :Thermal management; HVAC; heating ventilation and air conditioning; BEV; battery electric vehicle; simulation; Simulink; Värmehantering; HVAC; värme- och ventilationssystem; BEV; batteridrivna elfordon; simulering; Simulink.;

   Sammanfattning : I detta examensarbete simuleras ett värmehanteringssystem i Matlab Simulink för en elektrisk lastbil, det för att värmehantera fordonets klimat. Där en värmepump används för nedkylning av kupé och batteri samt en PTC (elektrisk värmare) för uppvärmning av detsamma. LÄS MER
