1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

   Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

   Författare :Johannes Lövhall; [2024]
   Nyckelord :Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

   Sammanfattning : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

3. 2. Method development of flow cytometry analysis of yeast and lactic acid bacteria viability for alcohol fermentation

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Författare :Megha Komahan; [2023]
   Nyckelord :Flow cytometry; yeast; lactic acid bacteria; fermentation; cell viability; applied microbiology; Technology and Engineering;

   Sammanfattning : The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design.

4. 3. Designing a Cost Effective Encoder for High Performance Doors

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Emanuel Edelstam; David Petersson; [2023]
   Nyckelord :Encoder; High speed doors; Motor; Product development; Prototyping; ASSA ABLOY; Technology and Engineering;

   Sammanfattning : Målet med detta arbete var att utveckla en prototyp av en kostnadseffektiv pulsgivare till motorerna för ASSA ABLOYs snabbrullduksportar. Pulsgivaren ger återkoppling till de automatiska dörrarnas kontrollsystem och ska göra detta på ett tillförlitligt sätt samtidigt som de ska vara mer kostnadseffektiva än de nuvarande lösningarna som används på ASSA ABLOY.

5. 4. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Elaheh Aghajafari; [2023]
   Nyckelord :III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

   Sammanfattning : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

7. 5. A Comparison Between KeyFrame Extraction Methods for Clothing Recognition

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

   Författare :Gabriel Lindgren; [2023]
   Nyckelord :key frame extraction; video analyzis; yolo; yolov7; optical flow; nyckelbildutvinning; videoanalys; yolo; yolov7; optiskt flöde;

   Sammanfattning : With an ever so high video consumption, applications and services need to use smart approaches to make the experience better for their users. By using key frames from a video, useful information can be retrieved regarding the entire video, and used for better explaining the content. LÄS MER
