1. 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
2. ETT NÖDVÄNDIGT ONT
Kandidat-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikationSammanfattning : Every day we are exposed to a large amount of advertisements. As social media has become an important part of many people's lives, advertising on these platforms has also become important for advertisers and major sources of income for the companies behind the social media.

3. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER
4. Femvertising: Dagens fluga eller tidlös fullträff?
Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionenSammanfattning : The purpose of this study is to investigate how femvertising, in specific advertising which aims to encourage female empowerment, is perceived by two generations of women and if it affects their attitudes toward an ad. The study is a replication of the previous study Advertising “like a girl”: Toward a better understanding of “femvertising” and its effects presented by Åkestam, Rosengren and Dahlén (2017). LÄS MER
5. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER
