1. 1. Virtual Test Cell : a Real-Time digital twin of an internal combustion engine

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Rasmus Malmqvist; [2024]
   Keywords : Virtual Test cell; Digital twin; Software in the loop; Real-time;

   Abstract : As the world is evolving faster and technology gets cheaper and more powerful, simulations are proving to be more and more beneficial. Simulations allow for faster development with less lead time between iterations which means that product versions can be released more often and at less cost. READ MORE

3. 2. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Jimmy Atterstig; [2024]
   Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

   Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

4. 3. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Nikolaos Charisoudis; [2024]
   Keywords : ;

   Abstract : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. READ MORE

5. 4. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Ellen Pääjärvi Våg; [2024]
   Keywords : Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

   Abstract : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. READ MORE

6. 5. A Comparative Investigation of Classical Random and Quantum Walks in Terms of Algorithms, Implementation, and Characteristics

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Naoki Moriya; [2024]
   Keywords : Qunatum computing; quantum walk;

   Abstract : In recent years, there has been a significant development in high performance computing, driven by advances in hardware and software technology. The performance of the computers to the present has improved in accordance with Moore’s law, on the other hand, it seems to be reaching the limits in the near future. READ MORE
