Prognosis of ball bearings with non-characteristic degradation using recurrent neural network
(Master thesis, 2019)Breakdowns in rotary machines are often related to bearing failure. In recentyears many prognostic and diagnostic models of bearings have been developedto prevent unexpected shutdowns. Estimating the remaining useful ... -
Hydrothermal Liquefaction of Lignin to Produce Bio-crude : Comparative Analysis of the Effects of Feedstock type and Operating Conditionson Bio-crude
(Master thesis, 2019)Lignin is one of the most abundant non-food biomass resources in the world today andseveral attempts are ongoingto harness its huge potential. Due to its rigid structure however, different processes are being experimented ... -
Optimization of Power Supply for Hydrology-and Meteorology-stations : Optimization of power supply for off-grid hydrology- and meteorology-stationsusing machine learning and genetic algorithm
(Master thesis, 2019)This thesis consider a case study of a PV/wind/battery hybrid energy system installed at Scanmatic ASheadquarters in Arendal, Norway. The energy system is a stand-alone and off-grid hybrid system. It consistof four PV ... -
A Language and Platform Independent Co-Simulation Framework Based on the Functional Mock-Up Interface
(Peer reviewed; Journal article, 2019)The main goal of the Functional Mock-up Interface (FMI) standard is to allow the sharing of simulation models across tools. To accomplish this, FMI relies on a combination of XML-files and compiled C-code packaged in a zip ... -
