11. Investigating the Spectral Bias in Neural Networks
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Neural networks have been shown to have astounding performance on a variety of different machine learning tasks and data sets, both for synthetic and real-world data.However, in spite of their widespread usage and implementation, the convergence and the training dynamics of neural networks are neither trivial, nor completely understood.

12. Fördelar med lågviktsdrivlina i vindkraftverk
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : I dagsläget finns det en mängd olika storlekar på vindkraftverk, allt från små landbaserade vindkraftverk på några hundra kilowatt till havsbaserade kraftverk på upp till 14 MW. Bland de största vindkraftverken ute till havs, är direktdrivna vindkraftverk dominerande på grund av en högre driftssäkerhet och livslängd på komponenterna. LÄS MER
13. Automatic data processing of traction motor measured data and vibration analysis of test bench
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : One of the goals of ABB AB is to develop highly efficient electric motors for traction application. The demand for traction motors is increasing due to the rise in electric vehicles sale and railway locomotive engines. LÄS MER
14. Paper Machine Press Felt Monitoring : A Case Study on PM2 in Karlsborg
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Press felts are highly critical components of the paper machine. A degraded press felt could lead to paper web breaks, which requires the paper machine to be restarted. Moreover, a degraded felt influences the quality of the paper, leading to paper disposal.

15. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.
