Lagrange Point Missions: The Key to next Generation Integrated Earth Observations. DSCOVR Innovation

open access: yesFrontiers in Remote Sensing, 2021
A new perspective for studying Earth processes has been soundly demonstrated by the Deep Space Climate Observatory (DSCOVR) mission. For the past 6 years, the first Earth-observing satellite orbiting at the Lagrange 1 (L1) point, the DSCOVR satellite has

Maggi’s Equations Used in the Finite Element Analysis of the Multibody Systems with Elastic Elements

open access: yesMathematics, 2020
The main method used to determine the equations of motion of a multibody system (MBS) with elastic elements is the method of Lagrange’s multipliers.

New analytical formalisms used in finite element analysis of robots with elastic elements

open access: yesJournal of Taibah University for Science, 2020
Obtaining the equations of motion for an element in finite element analysis (FEA) model in the analysis of a multi-body system (MBS) having component elastic elements represents an important (maybe the main) step to build a soft able to solve such a ...

Numerical aspects of two coupled harmonic oscillators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this study an interesting symmetric linear system is considered. As a first step we obtain the Lagrangian of the system. Secondly, we derive the classical Euler- Lagrange equations of the system.

Vortex clustering, polarisation and circulation intermittency in classical and quantum turbulence

open access: yesNature Communications, 2021
Turbulent flows may be regarded as an intricate collection of mutually-interacting vortices. Here, authors investigate the statistics of velocity circulation in quantum and classical turbulence and propose a connection between intermittency on both cases.

Ma fi gerger ziyada: the South Asian Character in Gulf Cultural Productions

open access: yesArabian Humanities, 2023
How is the noncitizen subaltern Other portrayed in Gulf cultural productions? While sociological studies argue that Gulf states have defined a national narrative centered on a purely Arab-Islamic identity excluding the Persian, African and South Asian ...

L’Exposition universelle de 1900 et les apories d’une « école italienne »

open access: yesILCEA, 2021
If Paris World’s Fairs had been the theatre of disapprovals towards the Italian artistic scene, critics blaming his decadence or his perverted cosmopolitism, 1900 World’s Fair begin, with his “Italian Palace”, a renewal taking his roots in Italian ...

The Optimal Time Window for Complex Training in Order to Increase Repeated Sprint Ability in Professional Ice Hockey Players

open access: yesInternational Journal of Strength and Conditioning, 2022
The goal of this study was to investigate the post-activation performance enhancement (PAPE) and optimal time window following complex training (CT) to increase ice-hockey player skating speed and endurance. Ten professional ice-hockey players (age= 19.8±
