Investigation of a novel numerical scheme for high-pressure supercritical fluids turbulence
(2022)
Research report
Open AccessHigh-pressure supercritical turbulence simulations are strongly susceptible to numerical instabilities. The multi-scale nature of the flow, in conjunction with the nonlinear thermodynamics and the strong density gradients ... -
Influence of honing parameters on the quality of the machined parts and innovations in honing processes
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-10)
Article
Open AccessThe article presents a literature review dealing with the effect of the honing parameters on the quality of the machined parts, as well as with the recent innovations in honing processes. First, an overview about the honing ... -
Experimental validation of ball burnishing numerical simulation on ball-end milled martensitic stainless-steel considering friction and the initial surface topography
(Elsevier, 2023-01)
Article
Open AccessNumerous simplified numerical models have been established to optimize the ball burnishing of steel surfaces. Nevertheless, their conceptualization has not considered the tool–part interaction, leading to an unsatisfactory ... -
Modified 2.5D singular boundary methods to deal with spurious eigensolutions in exterior acoustic problems
(2023-04)
Article
Open AccessThis paper studies the problem of spurious eigensolutions in the context of the singular boundary method (SBM) formulated in the two-and-a-half-dimensional (2.5D) domain and proposes two numerical schemes to overcome this ... -
An assessment of different relay network topologies to improve Earth-Mars communications
(2023-04)
Article
Open AccessThe future of deep space communications encompasses a challenging situation where the current facilities used to communicate with different spacecraft may become saturated as a result of an increasing number of missions ... -
Improvement of the pour plate method by separate sterilization of agar and other medium components and reduction of the agar concentration
(2023-01-10)
Article
Open AccessAlthough the pour plate method is widely employed in microbiological quality control, it has certain drawbacks, including having to melt the culture medium before seeding. In this study, the preparation of the culture ... -
Proximal fibular osteotomy vs high tibial osteotomy: an in-silico finite element study
(Springer, 2022)
Conference report
Restricted access - publisher's policyTypical treatments against Knee Osteoarthritis (KOA) are performed surgically, such as knee arthroplasty or High Tibial Osteotomy (HTO). In recent years, Proximal Fibular Osteotomy (PFO) has been proposed as a solution ... -
Effects of tendon compliance on the prediction of human squatting motion
(2022)
Conference report
Restricted access - publisher's policyPredictive simulations of human motion have the potential to aid the design of assistive devices, foresee surgical outcomes, and analyse isolated muscular features, which would otherwise be difficult to measure experimentally1. ... -
Architecture for determining the cleanliness in shared vehicles using an integrated machine vision and indoor air quality-monitoring system
(Springer Nature, 2023-02-02)
Article
Open AccessIn an attempt to mitigate emissions and road traffic, a significant interest has been recently noted in expanding the use of shared vehicles to replace private modes of transport. However, one outstanding issue has been ... -
Characterization of the fluid damping in simplified models of pump-turbines and high head Francis runners
(IOP Publishing, 2022)
Conference report
Open AccessIn order to satisfy the power demand in the electrical grid, hydraulic turbine units frequently work under off-design operation conditions and pass through transient events. These operation conditions can lead to high ... -
Microconfined high-pressure transcritical fluid turbulence
(2023-01-30)
Article
Open AccessMicrofluidics technology has grown rapidly over the past decades due to its high surface-to-volume ratios, flow controllability, and length scales efficiently suited for interacting with microscopic elements.However, as a ... -
A Legendre-Gauss pseudospectral collocation method for trajectory optimization in second order systems
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessPseudospectral collocation methods have proven to be powerful tools to solve optimal control problems. While these methods generally assume the dynamics is given in the first order form xdot = f(x, u, t), where x is the ...
