Laser powder bed fusion of steels : case studies on microstructures, mechanical properties, and notch-load interactions
(Lappeenranta-Lahti University of Technology LUT, 2022-11-10)
Additive manufacturing has evolved over the last few decades from utilising a prototyping approach to favouring a fabrication method. Consequently, this technology has become recognised as a potential replacement for ...
Chapter 3 - Global potential for renewable energy powered desalination in the irrigation sector
(Academic Press, 2022-10-14)
Water scarcity poses one of the greatest threats to conventional irrigation systems, a sector whose water demand is continuously growing. Despite the reliance on irrigation, the average global irrigation efficiency is ...
Computationally Efficient Practical Method for Solving the Dynamics of Fluid Power Circuits in the Presence of Singularities
(IEEE, 2020-11-18)
In this paper, a practical method is proposed for the efficient solution of fiuid power systems with singularities originating (in particular) from the presence in the system of small volumes. The method is based on the ...
Consequential life-cycle assessment of treatment options for repulping reject from liquid packaging board waste treatment
(Elsevier, 2022-11-21)
