HVLBuzz is a simulation tool to calculate the surface gradient of overhead power lines and predict the audible noise and electromagnetic field at ground. This tool only requires freely available Python libraries to run. The GUI is based on the Kivy framework, while the mathematical computations and plot generation rely on the widely used NumPy and Matplotlib.

A Monte Carlo collision code for the simulation of electron transport in low temperature plasmas
METHES is a freely available MATLAB code for the simulation of electron transport in arbitrary gas mixtures in the presence of uniform electric fields. For steady-state electron transport, the program provides the transport coefficients, reaction rates and the electron energy distribution function. The program uses established Monte Carlo techniques and is compatible with the electron scattering cross section files from the open-access Plasma Data Exchange Project LXCat. The code is written in object-oriented design, allowing the tracing and visualization of the spatiotemporal evolution of electron swarms and the temporal development of the mean energy and the electron number due to attachment and/or ionization processes. The code is benchmarked with well-known model gases as well as the real gases Ar, N2, O2, CF4, SF6 and mixtures of N2 and O2.

Electron and ion rate and transport coefficients in gases
Using a pulsed Townsend experiment, we measure the reaction rate coefficients of impact ionization, electron attachment, detachment and ion conversion, the electron and ion mobilities, and the longitudinal electron diffusion coefficient in various gases. The data is published in the database ETHZ, on the website of the Plasma data Exchange Project LXCat: external pagewww.lxcat.net/ETHZ.
Run-to-Failure Vacuum Circuit Breaker Mechanical Test Dataset
We performed an accelerated life testing for mechanical failures on a commercial VCB by doing close-open operations continuously every three minutes and automatically 24/7 until failure. In our experiments, the VCB operated more than 26000 close and open operations without current load with the time span of five months. The failure is the friction in the operating mechanism, causing the VCB not to be able to perform the open operation. Other scholars are invited to use the data-set for further analysis.

The data-set is stored here.
