About the chemical composition of delta Scuti - the prototype of the class of pulsating variables
, 2004 We present chemical abundances in the photosphere of $\delta$ Scuti -- the prototype of the class of pulsating variables -- determined from the analysis of a spectrum obtained at Terskol observatory 2 meter telescope with resolution $R=52,000$, signal to

International Journal of Rotating Machinery, Volume 2026, Issue 1, 2026.This work presents and validates a direct analytical methodology for the parametric hydrodynamic design of Pelton rotors. The proposed approach combines a one‐dimensional theoretical framework for defining global geometric rotor parameters with an inductive method for generating bucket geometry, formalized from a comprehensive mapping of a high ...

Energy Science &Engineering, Volume 13, Issue 12, Page 6003-6016, December 2025.ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.
