Numerical Analysis of the Effect of Offshore Turbulent Wind Inflow on the Response of a Spar Wind Turbine
(Peer reviewed; Journal article, 2020)Turbulent wind at offshore sites is known as the main cause for fatigue on offshore wind turbine components. Numerical simulations are commonly used to predict the loads and motions of floating offshore wind turbines; ... -
CO2 methanation on hydrotalcite-derived catalysts and structured reactors: A review
(Peer reviewed; Journal article, 2020)CO2 methanation reaction has attracted renewed interest since the power-to-gas (PtG) concept emerged as a promising alternative for CO2 emission abatement using surplus renewable electricity. Although the reaction has been ... -
The missing link of Rodinia break up in western South America: A petrographical, geochemical, and zircon Pb-Hf isotope study of the volcanosedimentary Chilla beds (Altiplano, Bolivia)
(Peer reviewed; Journal article, 2020)The assembly of Rodinia involved the collision of eastern Laurentia with southwestern Amazonia at ca. 1 Ga. The tectonostratigraphic record of the central Andes records a gap of ∼300 m.y. between 1000 Ma and 700 Ma, i.e., ... -
Compaction and Fluid—Rock Interaction in Chalk Insight from Modelling and Data at Pore-, Core-, and Field-Scale
(Peer reviewed; Journal article, 2020)Water weakening is a phenomenon that is observed in high porosity chalk formations. The rock interacts with ions in injected water and additional deformation occurs. This important effect needs to be taken into account ... -
Automated Data Filtering Approach for ANN Modeling of Distributed Energy Systems: Exploring the Application of Machine Learning
(Peer reviewed; Journal article, 2020)To realize the distributed generation and to make the partnership between the dispatchable units and variable renewable resources work efficiently, accurate and flexible monitoring needs to be implemented. Due to digital ... -
Decarbonization of the Iron and Steel Industry With Direct Reduction of Iron Ore with Green Hydrogen
(Peer reviewed; Journal article, 2020)Production of iron and steel releases seven percent of the global greenhouse gas (GHG) emissions. Incremental changes in present primary steel production technologies would not be sufficient to meet the emission reduction ... -
Fault-Tolerant Control Based on Virtual Actuator and Sensor for Discrete-Time Descriptor Systems
(Peer reviewed; Journal article, 2020)This article proposes a fault-tolerant control (FTC) strategy based on virtual actuator and sensor for discrete-time descriptor systems subject to actuator and sensor faults. The fault-tolerant closed-loop system, which ... -
Study of the Performance of Natural Fiber Reinforced Composites for Wind Turbine Blade Applications
(Peer reviewed; Journal article, 2020)Availability of some form of energy is essential for human survival and social development. However, the way energy has been generated within the last century has brought forward the quest for generation of energy without ... -
Recent developments and trends in the friction testing for conventional sheet metal forming and incremental sheet forming
(Peer reviewed; Journal article, 2020)Friction is the main phenomenon that has a huge influence on the flow behavior of deformed material in sheet metal forming operations. Sheet metal forming methods are one of the most popular processes of obtaining finished ... -
