Modelling the wear evolution of a single alumina abrasive grain: analyzing the influence of crystalline structure
(Elsevier, 2019-10-17)
The grinding process is continuously adapting to industrial requirements. New advanced materials have beendeveloped, which have been ground. In this regard, new abrasive grains have emerged to respond to the demands of ...
Analysis of the static and dynamic elastic moduli of a one-coat rendering mortar with laboratory and in situ samples
(Elsevier, 2024-07)
Although the compressive strength is the most commonly used property to characterize mortars, it has limited representativeness in real-world applications. The deformation properties of mortars, specifically the elastic ...
In-Process Machining Distortion Prediction Method Based on Bulk Residual Stresses Estimation from Reduced Layer Removal
(MDPI, 2024-01-03)
Manufacturing structural monolithic components for the aerospace market often involves machining distortion, which entails high costs and material and energy waste in industry. Despite the development of distortion calculation ...
Fatigue Life Estimation Model of Repaired Components with the Expanded Stop-Hole Technique
(MDPI, 2024-02-01)
Fatigue crack growth tests are conducted to assess the efficacy of the stop-hole crack repair method. This straightforward and widely adopted technique involves drilling a hole at the crack tip and subsequently enlarging ...
Failure-Analysis Based Redesign of Furnace Conveyor System Components: A Case Study
(MDPI, 2019-08)
Any manufacturing equipment designed from scratch requires a detailed follow-up of the performance for the first units placed in service during the production ramp-up, so that lessons learned are immediately implemented ...
ADITU: A mesh-free formulation for the solution of Helmholtz equation in bounded and unbounded domains
(Elsevier, 2022-06-01)
This work describes a mesh-free collocation formulation for the acoustic fluid–fluid coupling among
non-homogeneous bounded and unbounded fluid domains. The proposed formulations use series
of functions that are generated ...
A Hybrid Control Approach for the Swing Free Transportation of a Double Pendulum with a Quadrotor
(MDPI, 2021-06-13)
In this article, a control strategy approach is proposed for a system consisting of a quadrotor transporting a double pendulum. In our case, we attempt to achieve a swing free transportation of the pendulum, while the ...
Temperature based maximum power point tracking for photovoltaic modules
(Nature, 2020-07-27)
In this article authors propose a temperature based Maximum Power Point Tracking algorithm (MPPT). Authors show that there is an optimal current vs maximum power curve that depends on photovoltaic (PV) module temperature. ...
Hybrid Modeling of Deformable Linear Objects for Their Cooperative Transportation by Teams of Quadrotors
(MDPI, 2022-05-23)
his paper deals with the control of a team of unmanned air vehicles (UAVs), specifically quadrotors, for which their mission is the transportation of a deformable linear object (DLO), i.e., a cable, hose or similar object ...
A low-cost vision system for online reciprocal collision avoidance with UAVs
(Elsevier, 2024-05-10)
In this article, we propose a reciprocal collision avoidance system for autonomous drones, based on computer vision and using relative positioning in an indoor environment. This dynamic environment represents a demanding ...
