Electric drives with centrifugal torque characteristic are a typical low efficiency drives. These include fans, pumps, blowers etc. In these electric drives, there is great technical and economic potential for significant ...
This paper discusses the cleaning and digital restoration of lacquer records from the Reggae/Dancehall culture known as Dubplates. The paper evaluates the use of certain digital restoration tools used in the processing of ...
With the method and approach developed within the Fotom module, the results obtained are comparable to other volumetric instruments (e.g. OssiriX). This software product is free, easily accessible and applicable in healthcare ...
A recent development is the application of AI to either alter or create video and audio files – called Deepfakes. The paper examines the issues arising from deepfakes, to determine how robust the UK justice system is ...

Special issue (second volume): scientific papers from 14-th International conference on Electron Beam Technologies ...
Electron guns for processing applications typically use a thermionic cathode as the source of electrons, where the cathode is a resistively heated refractory metal ribbon. In order to keep the heat input to the gun reasonably ...
High power electron beam welding can be applied to structures such as pressure vessels with wall thicknesses of up to 200 mm. Such applications often make use of steels that exhibit ferromagnetic properties. If the work pieces ...
In this paper the electron beam welding of Ti–6Al–4V thin plates is simulated by implementation of a moving linear heat source model. The simulation results are used for estimation of regression models for the dependencies ...
In this paper the simulation of electron beam welding of Inconel 718 thin plates by a moving linear heat source is considered. Regression models for the molten pool geometry characteristics, depending on the electron beam ...
