An experimental exploration of the properties of random frequency response functions
(2021-01)
Article
Restricted access - publisher's policyThe vibro-acoustic analysis of complex structures over a broadband frequency range is an extremely challenging problem that may often require the use of a hybrid deterministic-statistical approach. Due to manufacturing ... -
Numerical validation of a hybrid approach for the assessment of vibrations and re-radiated noise in buildings due to railway traffic
(2020-12-25)
Article
Open AccessIn this paper, a hybrid experimental/numerical methodology for the assessment of railway induced ground-borne noise and vibration in buildings based on experimental measurement in the ground surface is proposed and validated. ... -
Superficial effects of ball burnishing on TRIP steel AISI 301LN sheets
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-03)
Article
Open AccessThis paper explores the consequences of applying an ultrasonic vibration-assisted ball burnishing process and its non-vibration assisted version on the topology and subsurface microstructure of a transformation-induced ... -
Prediction of mechanical properties of human rib cortical bone using fractal dimension
(Gordon and Breach Science Publishers, 2020-10-26)
Article
Restricted access - publisher's policyA large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed ... -

Ceramic paste extruder of 3D printing: status, types, and prospects
(Springer, 2021)
Article
Restricted access - publisher's policyAdditive manufacturing (AM) is an important, rapidly emerging, manufacturing technology that takes the information from a computer-aided design (CAD) and builds parts in a layer-by-layer style. Since about three decades ... -
Investigation on electromagnetic vibration energy harvesting in water distribution control valves
(2020)
Article
Open AccessControl stations of a water distribution system monitor several variables such as the pressure, the flow, and the quality of water. For these monitoring tasks, wireless sensor networks with ultra-low power consumption ... -
Systematic review on wearable lower-limb exoskeletons for gait training in neuromuscular impairments
