Experimental comparison of two testing setups for characterizing the shear mechanical properties of masonry
(Elsevier, 2021-09-08)
Article
Restricted access - publisher's policyThe prediction of the structural capacity of masonry buildings against lateral loads requires an accurate characterization of the masonry strength and the general response under shear stresses. The experimental determination ... -
Improved damage detection in Pelton turbines using optimized condition indicators and data-driven techniques
(2021-01-07)
Article
Open AccessThe health condition of hydraulic turbines is one of the most critical factors for the operation safety and financial benefits of a hydro power plant. After the massive entrance of intermittent renewable energies, hydropower ... -
Large-eddy simulation of cavitating tip leakage vortex structures and dynamics around a NACA0009 hydrofoil
(MDPI, 2021-11-01)
Article
Open AccessThe tip leakage vortex (TLV) has aroused great concern for turbomachine performance, stability and noise generation as well as cavitation erosion. To better understand structures and dynamics of the TLV, large-eddy simulation ... -
Investigation of ball burnishing process using vibration and acoustic emission sensors
(Institute of Physics (IOP), 2021-10-01)
Article
Open AccessIn this paper, a ball burnishing tool mounted in a CNC lathe is characterized. This tool may work as vibration assisted ball-burnishing tool and in conventional way. The characterization consists of acoustic emission ... -
A predictive model for fracture in human ribs based on in-vitro acoustic emission data
(2021-09-01)
Article
Restricted access - publisher's policyPurpose The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The ... -
Ultrasonic vibration-assisted ball burnishing tool for a lathe characterized by acoustic emission and vibratory measurements
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
Article
Open AccessThis paper focuses on a resonant system used to induce a low-amplitude movement and ultrasonic frequency to complement a ball burnishing process on a lathe. The system was characterized through the combination of different ... -
Numerical and experimental analysis of a high-throughput blood plasma separator for point-of-care applications
(2021-05)
Article
Restricted access - publisher's policyBlood plasma separation from undiluted blood is an essential step in many diagnostic procedures. This study focuses on the numerical optimization of the microfluidic blood plasma separator (BPS) and experimental validation ... -
Understanding the influence of wake cavitation on the dynamic response of hydraulic profiles under lock-in conditions
(2021-09-22)
Article
Open AccessTo accelerate the integration of fluctuating renewable energy technologies in the power systems, it is necessary to increase the flexibility of hydropower by operating turbines at off-design conditions. Unfortunately, this ... -
Recent impact of microfluidics on skin models for perspiration simulation
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-21)
Article
Open AccessSkin models offer an in vitro alternative to human trials without their high costs, variability, and ethical issues. Perspiration models, in particular, have gained relevance lately due to the rise of sweat analysis and ... -
Numerical investigation on train-induced environmental vibration in floating ladder tracks
(2020-10-15)
Article
Open AccessA floating ladder track is established in the present paper as a next-generation non-ballasted track system. The three-dimensional model consists of a track (mass-spring-damping system) and the underlying soil. Rectangular ... -
3D printed prototype of a complex neuroblastoma for preoperative surgical planning
(Elsevier BV, 2021-06)
Article
Open AccessNeuroblastoma is the most common abdominal solid tumour in childhood. Its removal implies a complex surgery that requires surgical experience due to the usual encassement of major abdominal blood vessels. Standard surgical ... -
