1. 1. Formulation and characterisation of novel edible-packaging for fruits and vegetables

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Lola Sutton; Katerina Papa; [2023]
   Nyckelord :algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

   Sammanfattning : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. LÄS MER

3. 2. Taking Flight Towards a Greener Future: Steps Airlines Can Take to Reduce Emissions

   Kandidat-uppsats, Lunds universitet/Trafikflyghögskolan

   Författare :Rabin Kronold; Mikael Nyström; [2023]
   Nyckelord :Sustainability; Aviation; Management; Emissions; Carbon footprint; Ground and aircraft operation; Fuel consumption; Contrails; Aircraft-Induced Clouds; Greenhouse gas emissions; Sustainable Aviation Fuel; FLYL01; Technology and Engineering;

   Sammanfattning : Background: For decades, aviation has been an important part of society and with its growth comes the increased environmental impact and the challenge to reduce this adversary effect and move towards sustainability. Objective: Find out how airlines can reduce their emissions and become more sustainable. LÄS MER

4. 3. Skolvägen ur barns perspektiv : en studie över barns rörelse genom sin närmiljö

   Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Författare :Louise Pira; [2023]
   Nyckelord :barns perspektiv; barns hälsa; rörelsefrihet; trafikmiljö; vardagsmiljö; trygghet; säkerhet;

   Sammanfattning : Att barn har tillgång till en trygg och säker skolväg är grundläggande för barns rörelsefrihet. En bra skolväg har potentialen att öka barns fysiska aktivitet och självständiga rörelse. LÄS MER

5. 4. Improving Behavior Trees that Use Reinforcement Learning with Control Barrier Functions : Modular, Learned, and Converging Control through Constraining a Learning Agent to Uphold Previously Achieved Sub Goals

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

   Författare :Jannik Wagner; [2023]
   Nyckelord :Behavior Trees; Reinforcement Learning; Control Barrier Functions; Robotics; Artificial Intelligence; Verhaltensbäume; Verstärkendes Lernen; Kontrollbarrierefunktionen; Robotik; Künstliche Intelligenz; Beteendeträd; Förstärkningsinlärning; Kontrollbarriärfunktioner; Robotik; Artificiell Intelligens;

   Sammanfattning : This thesis investigates combining learning action nodes in behavior trees with control barrier functions based on the extended active constraint conditions of the nodes and whether the approach improves the performance, in terms of training time and policy quality, compared to a purely learning-based approach. Behavior trees combine several behaviors, called action nodes, into one behavior by switching between them based on the current state. LÄS MER

7. 5. Biocatalysis in Pickering emulsions

   Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Författare :Christine Vera Isabel Schmidt; [2023]
   Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

   Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER
