Assessing multi‐sensor hourly maize evapotranspiration estimation using a one‐source surface energy balance approach

open access: yesIrrigation 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 ...

Homotheties of a Class of Spherically Symmetric Space‐Time Admitting G3 as Maximal Isometry Group

open access: yesAdvances in Mathematical Physics, Volume 2018, Issue 1, 2018., 2018
The homotheties of spherically symmetric space‐time admitting G4, G6, and G10 as maximal isometry groups are already known, whereas, for the space‐time admitting G3 as isometry groups, the solution in the form of differential constraints on metric coefficients requires further classification. For a class of spherically symmetric space‐time admitting G3

Linear sets in the projective line over the endomorphism ring of a finite field

open access: yes, 2016
Let $\mathrm{PG}(1,E)$ be the projective line over the endomorphism ring $E=End_q({\mathbb F}_{q^t})$ of the $\mathbb F_q$-vector space ${\mathbb F}_{q^t}$.

Nilpotent Singer groups [PDF]

open access: yes, 2006
Let $N$ be a nilpotent group normal in a group $G$. Suppose that $G$ acts transitively upon the points of a finite non-Desarguesian projective plane $\mathcal{P}$.

Two dimensional dynamical systems which admit Lie and Noether symmetries

open access: yes, 2011
We prove two theorems which relate the Lie point symmetries and the Noether symmetries of a dynamical system moving in a Riemannian space with the special projective group and the homothetic group of the space respectively.

Concircular vector fields for Kantowski Sachs and Bianchi type III spacetimes

open access: yes, 2017
This paper intends to obtain concircular vector fields of Kantowski Sachs and Bianch type III spacetimes. For this purpose, ten conformal Killing equations and their general solution in the form of conformal Killing vector fields are derived along with ...

Treacher Collins Syndrome [PDF]

open access: yesSeminars in Plastic Surgery, 2012
Treacher Collins syndrome is a genetic disorder resulting in congenital craniofacial malformation. Patients typically present with downslanting palpebral fissures, lower eyelid colobomas, microtia, and malar and mandibular hypoplasia. This autosomal dominant disorder has a variable degree of phenotypic expression, and patients have no associated ...

On the symmetric block design with parameters (153, 57, 21)

open access: yesLe Matematiche, 2009
In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and

Treacher Collins syndrome [PDF]

open access: yesHuman Molecular Genetics, 1995
Treacher Collins syndrome is an autosomal dominant disorder of craniofacial development, the features of which include conductive hearing loss and cleft palate. In the absence of a candidate gene, a positional cloning approach has been used to isolate the mutated gene which maps to chromosome 5q31.3-32.
