Damage regression
No full textThe data contains the input and target values for training the machine learning model. The input contains the Relative Frequency Shifts for the first eight modes of transverse vibration for a cantilever beam that is affected by a transverse crack and in some scenarios also by imperfect boundary conditions
Climate change perceptions_Health_Generations
No full textInterview data with Millennials and Generation Z about climate change-health concern nexus
Media Reporting on Clientelism in Romania (2012-2020)
No full textThe dataset includes media reporting about clientelist practices in Romania during the local and national elections 2012-2020
DFT-ANN database
No full textA set of data usable to train an ANN in order to find correction terms for different DFT amplitudes.
To generate more training data or data to test the network you can use the "Data generator". First generate signals with different parameters (number of samples, sampling frequency, amplitude, phase, frequency etc.) Afterward use "Python_DFT - SINC OK" to find the DFT amplitudes and the correction term
FEM simulation results
No full textThe dataset contains the relative frequency shift values for the first eight weak-axis bending vibration modes obtained by simulation using Ansys, for a cantilever beam with the following dimensions: length 1000 mm, width 50 mm, and thickness 5 mm. The elements are hexahedral and have a 1 mm maximum edge size. The beam is fixed at the left end
Training data for cantilever beam with transverse cracks
No full textThis dataset contains the input and target data generated by using a mathematical relation to predict frequency changes for cantilever beams affected by transverse cracks.
The input data is as follows:
- the column represents the first eight relative frequency shift values for out-of-plane bending vibration modes.
- each column represents the damage location and severity, after the hole beam is scanned, we produce cracks also at the fixed end to simulate imperfect boundary conditions
