Data quality issues for vibration sensors: a case study in ferrosilicon production
Waszak, Maryna; Moen, Terje; Eidnes, Sølve; Stasik, Alexander Johannes; Hansen, Anders; Bouquet, Gregory; Pultier, Antoine; Ma, Xiang; Tørlen, Idar; Henriksen, Bjørn; Aamodt, Arianeh; Roman, Dumitru (Chapter, 2022)Digitisation in the mining and metal processing industries plays a key role in their modernisation. Production processes are more and more supported by a variety of sensors that produce large amounts of data that meant to ... -
Data quality issues in solar panels installations: a case study
Roman, Dumitru; Pultier, Antoine; Ma, Xiang; Soylu, Ahmet; Ulyashin, Alexander (Chapter, 2022)Solar photovoltaics (PV) is becoming an important source of global electricity generation. Modern PV installations come with a variety of sensors attached to them for monitoring purposes (e.g., maintenance, prediction of ... -
The influence of parent austenite characteristics on the intervariant boundary network in a lath martensitic steel
Mirzaei, Ahmad; Ghaderi, Razieh; Hodgson, Peter D.; Ma, Xiang; Rohrer, Gregory S.; Beladi, Hossein (Peer reviewed; Journal article, 2022)The influence of the parent austenite deformation state on the intervariant boundary network (i.e., population, plane orientation, and connectivity) of a lath martensitic microstructure was investigated using conventional ... -
Laser welding of niobium to AISI 304 steel using a copper interlayer
Zhao, Jian; Shi, Mingxiao; Li, Yanjun; Ma, Xiang; Fang, Zhenxing; Yan, Hua (Peer reviewed; Journal article, 2020)Cu interlayers with thicknesses of 1, 1.5, and 2 mm were used to join niobium and AISI 304 steel. Fractures occurred in the weld, the Nb base metal, and the unmelted Cu interlayer when the Cu interlayer thickness was 1, ... -
Magnesiothermic Reduction of Silica: A Machine Learning Study
Tang, Kai; Rasouli, Azam; Safarian, Jafar; Ma, Xiang; Tranell, Maria Gabriella (Journal article; Peer reviewed, 2023)undamental studies have been carried out experimentally and theoretically on the magnesiothermic reduction of silica with different Mg/SiO2 molar ratios (1–4) in the temperature range of 1073 to 1373 K with different ... -
Molecular Dynamics Simulation for Structural Evolution of Mixed Ash from Coal and Wheat Straw
Ji, Hengsong; Li, Xiang; Zhang, Mei; Li, Zhenqiang; Zhou, Yan; Ma, Xiang (Peer reviewed; Journal article, 2022)We conducted molecular dynamics (MD) simulations to investigate the structural evolution of molten slag composed of wheat straw (WS) and Shenhua (SH) coal. The content of wheat straw in the slag was varied from 0 to 100 ... -
