1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder
Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskapSammanfattning : 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.

2. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy
Kandidat-uppsats, Lunds universitet/Fysiska institutionenSammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER
3. Svenska gymnasieelevers svårigheter med bevis i geometri : En empirisk undersökning med van Hieles teori som ramverk
Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakultetenSammanfattning : Detta arbete undersöker svenska gymnasieelevers bevisföringsförmåga inom geometri med van Hieles modifierade modell som ramverk. Studien bygger på vårt tidigare examensarbete Elevers svårigheter med bevisföring inom geometri (Strandler & Mach, 2022), där internationella studier kring området sammanfattades. LÄS MER
4. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER
5. Traditionell undervisning gentemot det kooperativa lärandet : En interventionsstudie om användningen av det kooperativa lärandet i matematikundervisningen
Uppsats för yrkesexamina på avancerad nivå, Södertörns högskola/LärarutbildningenSammanfattning : This study aims to investigate the effects of cooperative learning on pupils’ knowledge and development with a particular focus on concepts and conceptual understanding in mathematics. By employing both qualitative and quantitative research methods, the study compared the effectiveness of cooperative learning to traditional teaching approaches in grade 4. LÄS MER
