Irrigation and Drainage, Volume 73, Issue 3, Page 988-1009, July 2024.Abstract In this study, the performance of a one‐source surface energy balance (OSEB) remote sensing (RS) of actual crop evapotranspiration (ETa), incorporating data from different spaceborne, airborne and proximal multispectral data, was evaluated. The RS platforms in this study included Landsat‐8 (30 m pixel size), Sentinel‐2 (10 m), Planet CubeSat ...

Riemann Solitons and Ricci Bi-Conformal Vector Fields on 4-Dimensional Oscillator Group
MathematicsWe consider Riemann soliton vector fields and Ricci bi-conformal vector fields on the oscillator group. We prove that the oscillator group admits Riemann solitons. Subsequently, we provide a complete classification of all Ricci bi-conformal vector fields

Irreducible collineation groups with two orbits forming an oval [PDF]
, 2007 Let G be a collineation group of a finite projective plane P of odd order fixing an oval Ω. We investigate the case in which G has even order, has two orbits Ω_0 and Ω_1 on Ω, and the action of G on Ω_0 is primitive.We show that if G is irreducible ...

Collineation Groups of Generalized André Planes
, 1969 In a previous paper (5), I constructed a class of translation planes, called generalized André planes or λ-planes, and discussed the associated autotopism collineation groups.

Irreducible collineation groups fixing a hyperoval [PDF]
, 2002 Let G be an irreducible collineation group of a finite projective plane P of even order n congruent to 0 mod 4. Our goal is to determine the structure of G under the hypothesis that G fixes a hyperoval W of P. We assume |G| congruent to 0 mod 4. If G

The nonexistence of projective planes of order 12 with a collineation group of order 16 [PDF]
, 2004 In this article, we prove that there is no projective plane of order 12 admitting a collineation group of order 16 by showing the nonexistence of some orthogonal arrays OA(72,12,6,2).
