Energy systems transformation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
SignificanceEnergy systems based on fossil fuels and uranium have brought about modernity and its specific agro-industrial metabolism. Although this achievement creates a deep lock-in effect, collateral damages such as climate change and large-scale contamination cast doubts on the sustainability of the current mode of global socioeconomic operation ...

Energy Transformer

open access: yes, 2023
Our work combines aspects of three promising paradigms in machine learning, namely, attention mechanism, energy-based models, and associative memory. Attention is the power-house driving modern deep learning successes, but it lacks clear theoretical foundations. Energy-based models allow a principled approach to discriminative and generative tasks, but

Energy States of Colored Particle in a Chromomagnetic Field [PDF]

open access: yes, 2006
The unitary transformation, which diagonalizes squared Dirac equation in a constant chromomagnetic field is found. Applying this transformation, we find the eigenfunctions of diagonalized Hamiltonian, that describe the states with definite value of ...

Predictive Control for Current Distortion Mitigation in Mining Power Grids

open access: yesApplied Sciences, 2023
Current distortion is a critical issue of power quality because the low frequency harmonics injected by adjustable speed drives increase heating losses in transmission lines and induce torque flickering in induction motors, which are widely used in ...

Simulation calculation of electric field protection for live working on Ultra-high voltage transmission line

open access: yesThe Journal of Engineering, 2019
The current standards related to live working provide no determined path for equal potential working, in which only safety distance is referred, so that the works are often executed relying on the line maintenance experience.
