1. 1. Design of a modular small-scale PMMA/Air hybrid rocket research engine

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

   Författare :Gustaf von Platen; [2023]
   Nyckelord :hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

   Sammanfattning : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

   Sammanfattning : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. LÄS MER

   Sammanfattning : Huvudregeln för bestämmandet av hyran i svensk rätt är att hyran ska vara till beloppet bestämd av parterna i avtalet. Bestämmelsen återfinns i 12 kap. 19 § Jordabalken (1970:994). LÄS MER

5. 4. Bör folkets åsikt beaktas? - en rättslig analys av det allmänna rättsmedvetandet

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen

   Författare :Victor Gullers Ahlin; [2017]
   Nyckelord :legal history; law; criminal law; Law and Political Science;

   Sammanfattning : The purpose of this essay has been to review the concept “the public’s sense of justice”. Ever since the 1980s, the term has become increasingly prevalent in preparatory work aswell as political and mediocre discussions on legislation and justice. The public’s sense of justice is particularly common in Swedish crime policy. LÄS MER

7. 5. Multi-objective Optimization of Fenestration Design in Residential spaces. The Case of MKB Greenhouse, Malmö, Sweden

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Iason Bournas; Ludvig Haav; [2016]
   Nyckelord :overheating time; heating; daylighting; fenestration; optimization; residential; Technology and Engineering;

   Sammanfattning : This thesis investigates the optimization of fenestration design for multi-family apartments, considering the heating demand, daylight autonomy as well as overheating. A literature review was conducted to situate the thesis focus within the broader academic field of façade optimization, and a specific apartment located in the city of Malmö was chosen as the study object.
