Euclid preparation. Constraining parameterised models of modifications of gravity with the spectroscopic and photometric primary probes Open
The Euclid mission has the potential to understand the fundamental physical nature of late-time cosmic acceleration and, as such, of deviations from the standard cosmological model, LCDM. In this paper, we focus on model-independent method…

A model-independent reconstruction of the matter power spectrum Open
We propose a new model-independent reconstruction method for the matter power spectrum based on its time dependence and a combination of observations from different redshifts. The method builds on a perturbative expansion in terms of the l…

Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes Open
The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic scales. We focus on modified gravity models characterised, at linear scales, by a scale-in…

Micro Phasor Measurement Units: a Review from the Prosumer Point of View Open
In recent years, power grid infrastructure has moved from a centralized power generation model to a paradigm in which generation capacity is distributed across an increasing number of small power plants that rely on renewable energy source…

Euclid: Constraints on f(R) cosmologies from the spectroscopic and photometric primary probes Open
$\textit{Euclid}$ will provide a powerful compilation of data including spectroscopic redshifts, the angular clustering of galaxies, weak lensing cosmic shear, and the cross-correlation of these last two photometric observables. In this st…

System for repetitive battery charge and discharge tests for battery life analysis Open
Lead-acid batteries are and will still be widely used to power various electrical systems. Unfortunately,these are found for most of the time at rest and by the time they are called to work,they could be out of order, creating real problem…
