Failure of confined granular media due to pullout of an intruder: from force networks to a system wide response
(Royal Society of Chemistry, 2020-07-17)
We investigate computationally the pullout of a spherical intruder initially buried at the bottom of a granular column. The intruder starts to move out of the granular bed once the pulling force reaches a critical value, ...
The effects of pretreatment and coating on the formability of extrusion‐coated multilayer paperboard–plastic composites
(John Wiley & Sons, 2020-10-30)
Sustainable materials like paperboard can substitute for crude oil‐based polymers in packaging applications and, by doing that, reduce the negative environmental impacts caused by plastic waste. For a broader application ...
Simulation Model to Investigate Effect of Support Stiffness on Dynamic Behaviour of a Large Rotor
(CRC Press/Balkerna, 2020-10-23)
In this study, the effect of support stiffness on the dynamic behaviour of a large industrial rotor is studied using simulation models and experimental test setup having a mechanical apparatus for changing the horizontal ...
The role of renewable energy based seawater reverse osmosis (SWRO) in meeting the global water challenges in the decades to come
(Lappeenranta-Lahti University of Technology LUT, 2020-11-25)
Renewable energy (RE) powered desalination is rapidly gaining interest as a means to augment the increasingly stressed global water supply. This thesis introduces and describes the ways in which 100% RE-based seawater ...
Numerical modelling of sorption-enhanced gasification: Development of a fuel decomposition model
(Elsevier, 2020-12-16)
Sorption-enhanced gasification (SEG) is a promising technology for producing renewable feedstock gas to be used in biofuel synthesis processes, especially in dimethyl ether (DME) synthesis. To adopt the technology on a ...
5-Dimensional Definition for a Manufacturing Digital Twin
(Elsevier, 2020-02-07)
The Digital Twin is a recently developed innovative technology in Industry 4.0. The cyber-physical system (CPS) is a concept closely connected with Industry 4.0 that can form a basis for creating a Digital Twin. In this ...
Color Laser Marking: Repeatability, Stability and Resistance Against Mechanical, Chemical and Environmental Effects
(IEEE, 2020-11-26)
In this paper, utilizing the technology of color laser marking of stainless steel in industrial productions is investigated from the perspective of repeatability and stability of produced color markings. The color laser ...
Impact of utilizing solid recovered fuel on the global warming potential of cement production and waste management system: A life cycle assessment approach
(SAGE Publishing, 2020-12-25)
Cement production is responsible for a significant share of global greenhouse gas (GHG) emissions. A potential option to reduce the cement production emissions is to use alternative fuels which can have also an impact on ...
