Greening elements in the distribution networks
Due to climate change and the increase in environmental awareness in the world, the concept of Green Supply Chain Management appeared. The concept is aimed at the reduction of several elements: energy, materials, the pollution and the waste in production

A distributional Hardy transformation [PDF]
In this paper the classical Hardy transformation (5) has been extended to distributions. The celebrated Hankel transformation, Y-transformation and H-transformation are particular cases of the Hardy transformation. The Hankel transformation has been extended to distributions by Zemanian(12).

Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions [PDF]
Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current.

Adjustment of model parameters to estimate distribution transformers remaining lifespan [PDF]
Currently, the electrical system in Argentina is working at its maximum capacity, decreasing the margin between the installed power and demanded consumption, and drastically reducing the service life of transformer substations due to overload (since the ...

The Power of Convex Algebras [PDF]
Probabilistic automata (PA) combine probability and nondeterminism. They can be given different semantics, like strong bisimilarity, convex bisimilarity, or (more recently) distribution bisimilarity.
