Modello di ottimizzazione per l'assegnazione del personale all'assistenza voli: il caso SAT [PDF]

open access: yes, 2007
Lo studio si concentra nella ricerca di modelli di programmazione lineare intera. I modelli cercano di trovare l'assegnazione ottima degli operatori che lavorano per offrire un'assistenza ai voli in sosta nel piazzale aeromobile dell'aeroporto Galileo ...

Semianalytical Approximation of the Fluid Drag in Projectile Motion Using Newton′s Equation of Motion

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
A body moving in a fluid experiences some of the fluid‐induced forces, which may derail the body from its fluid‐free trajectory and consequently transform its maximum height reached, time of flight, and range. These forces include upthrust, drag, and lift. Other than upthrust, an accurate description of drag and lift remains uncertain.

Galileo Galilei, los climas, y la tradición del Tractatus de sphrera de Johannes de Sacrobosco [PDF]

open access: yes, 2010
Este traba¡o estucha una obra poco conocida de Galileo Galilei: el Trattoto della sfera ovvero cosmografía que él compuso aproximadamente en el 1596 (seguramente antes del 1604), cuando todavía no defendía el sistema de Copérnico (Favaro, 1891 )

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift

open access: yesAnnalen der Physik, Volume 537, Issue 11, November 2025.
The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

How many fluxes fit in an EFT?

open access: yesJournal of High Energy Physics, 2019
We extend the recent construction of 4d N = 1 $$ \mathcal{N}=1 $$ three-form Lagrangians by including the most general three-form multiplets necessary to reproduce any F-term potential in string flux compactifications.

JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

open access: yesAstronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

Stemflow Hydrodynamics

open access: yesReviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Stemflow hydrodynamics is the study of water movement along the exterior surface area of plants. Its primary goal is to describe water velocity and water depth along the stem surface area. Its significance in enriching the rhizosphere with water and nutrients is not in dispute.

A joint JWST and HST view of Omega Centauri: Multiple stellar populations and their kinematics

open access: yesAstronomy & Astrophysics
We combine F115W and F277W images collected with the Near Infrared Camera of the James Webb Space Telescope with multiband, multi-epoch Hubble Space Telescope observations of ω Centauri to investigate its multiple stellar populations and internal ...
