12. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER
13. Introducing Software Sustainability Demands into Large Organisational Procurement Processes
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Industriell teknikSammanfattning : As the ICT sector saw exponential growth over the last few decades, so too did the greenhouse gas emissions caused by it, to the point where the ICT sector is at least as big, if not bigger, than the airline industry. Previous research in this field has circled around methodologies for performing life cycle assessment of ICT software products, but has not put it in an organisational context which has lead to no agreed upon way of calculating and comparing sustainable software.

14. Passenger flow prediction : Finding and developing a sustainable machine learning model for airport passenger flow prediction
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Matematiska institutionenSammanfattning : There are many outdated routines and processes in today's aviation industry that major airlines lack the motivation to update. While this may not hold any direct security concerns, it creates bottlenecks at checks and high salary costs for otiose airport personnel. LÄS MER
15. Evaluating the quality of ultrasonic signals using machine learning : A comparative study on binary classification methods applied on ultrasonic chirp signals
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Advanced bolt-tightening tools such as automatic nutrunners are commonly used in industrial factories to streamline the assembly process. In safety-critical systems, it is crucialto control the tightening process. LÄS MER
