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 ...
Active Learning for Road Lane Landmark Inventory with V-ELM in Highly Uncontrolled Image Capture Conditions
(Elsevier, 2021-05-28)
Road landmark inventory is becoming an important data product for the maintenance of transport infrastructures. Several commercial sensors are available which include synchronized optical cameras that allowto build 360° ...
Above-ground biomass estimation from LiDAR data using random forest algorithms
(Elsevier, 2022-02)
Random forest (RF) models were developed to estimate the biomass for the Pinus radiata species in a region of the Basque Autonomous Community where this species has high cover, using the National Forest Inventory, allometric ...
Delamination Fracture Behavior of Unidirectional Carbon Reinforced Composites Applied to Wind Turbine Blades
(MDPI, 2021-01-27)
One of the materials that is used widely for wind turbine blade manufacturing are fiber-reinforced composites. Although glass fiber reinforcement is the most used in wind turbine blades, the use of carbon fiber allows ...
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 ...
