Triangular Bézier sub-surfaces on a triangular Bézier surface [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2011
The authors provide a more convenient method for computing the Bézier representation for a triangular sub-patch on a triangular Bézier surface. An explicit compact formula to compute the control points of the composition is deduced. The authors simplify the formula to express the control points of the triangular Bézier sub-patch as linear combinations ...

On Triangular Multisets and Triangular Fuzzy Multisets [PDF]

open access: yesMathematics, 2022
The basic set operations between fuzzy sets are defined using the min and max functions; however, later on, new operators were introduced that used other functions, which, nevertheless, had similar properties to functions min and max. The resulting fuzzy

Flow field and Reynolds stress distribution in low turbulance natural convection in a triangular cavity [PDF]

open access: yes, 2006
Triangular enclosures are typical configurations found in attic spaces of residential as well as industrial pitched-roof buildings. Previous studies on airflow within such spaces have focused on the laminar range.

Evaluation of the Residence Time Distribution (RTD) for Flow in Ducts with Velocity Profile of Two Independent Variables [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2022
The correct information on RTD can help in system design and evaluation. The RTD corresponding to the velocity profile is known only for certain cases, where the velocity profile depends on one coordinate only.

Classification of limits of upper triangular matrix algebras. [PDF]

open access: yes, 1993
Let Tn be the operator algebra of upper triangular n × n complex matrices. Three families of limit algebras of the form lim (Tnk) are classified up to isometric algebra isomorphism: (i) the limit algebras arising when the embeddings Tnk→Tnk+1, are ...

Triangular Trimers on the Triangular Lattice: An Exact Solution [PDF]

open access: yesPhysical Review Letters, 1999
A model is presented consisting of triangular trimers on the triangular lattice. In analogy to the dimer problem, these particles cover the lattice completely without overlap. The model has a honeycomb structure of hexagonal cells separated by rigid domain walls.
