16. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER
17. Data Analysis for Predictive Maintenance of a Straightening Machine in the Steel Industry
Magister-uppsats, Högskolan i Gävle/ElektronikSammanfattning : The availability of industrial machinery is crucial to any business operating in the manufacturingsector. Mechanical failures halt production and unplanned downtime canbe disruptive and costly. Small failures can compound to serious failures which exponentiallyincreases downtime and repair costs. LÄS MER
18. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER
19. Konditionsbedömning av en grupp transformatorer på Forsmark kärnkraftverk : Modellbaserad åldringsanalys av transformatorer
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This thesis used a model-based approach to assess the condition of a group of transformers at Forsmark nuclear plant. Since it’s problematic for practical and economic reasons to examine the paper insulation by inspection, this approach was chosen. LÄS MER
20. Dielectric properties of ion-exchanged electrotechnical insulation papers : A study on the properties of novel papers
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electrical insulation papers are a widely used group of papers in insulation applications and has been used for more than 100 years. Common applications include use as the dielectric medium in capacitors and insulation material in cables, bushings and transformers. LÄS MER
