Fine Spectra of Upper Triangular Triple-Band Matrices over the Sequence Space ()

open access: yesAbstract and Applied Analysis, 2013
The fine spectra of lower triangular triple-band matrices have been examined by several authors (e.g., Akhmedov (2006), Başar (2007), and Furken et al. (2010)). Here we determine the fine spectra of upper triangular triple-band matrices over the sequence

Some remarks on the visual angle metric [PDF]

open access: yes, 2015
We show that the visual angle metric and the triangular ratio metric are comparable in convex domains. We also find the extremal points for the visual angle metric in the half space and in the ball by use of a construction based on hyperbolic geometry ...

Variant Course of Posterior Circumflex Humeral Artery Associated with the Abnormal Origin of Radial Collateral Artery: Could It Mimic the Quadrangular Space Syndrome? [PDF]

open access: yesActa Medica Iranica, 2012
Variations in the origin of axillary artery branches are common. But, distinctly abnormal course of its posterior circumflex humeral branch is rare.

Triangular derivations related to problems on affine 𝑛-space [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
This paper studies the Cancellation Problem, the Embedding Problem, and the Linearization Problem. It shows how these problems can be related to a special class of locally nilpotent derivations.

Prediction the concentration of graphite direct exfoliation by liquid solution with solubility parameters map

open access: yesAIP Advances, 2018
This study is to discuss solvent selection with graphene dispersion concentration of directly exfoliation graphite. That limiting boundaries of fractional cohesion parameters will be draw on the triangular diagram to prediction and estimate.

Folding transition of the triangular lattice in a discrete three--dimensional space [PDF]

open access: yes, 1995
A vertex model introduced by M. Bowick, P. Di Francesco, O. Golinelli, and E. Guitter (cond-mat/9502063) describing the folding of the triangular lattice onto the face centered cubic lattice has been studied in the hexagon approximation of the cluster ...

Triangular Cooperation: Enabling Policy Spaces [PDF]

open access: yes, 2020
AbstractIn the past decade, a number of studies, reports, and data have been produced on triangular cooperation (TrC). The focus of these publications is mainly on (i) the project level and/or (ii) political relations between stakeholders. I argue that, beyond being an effective modality for the implementation of development projects, TrC is an enabler

Quasi-homogeneous associative functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
A triangular norm is a special kind of associative function on the closed unit interval [0,1]. Triangular norms (or t-norms) were introduced in the context of probabilistic metric space theory, and they have found applications also in other areas, such ...

The Temperature Vegetation Dryness Index (TVDI) Based on Bi-Parabolic NDVI-Ts Space and Gradient-Based Structural Similarity (GSSIM) for Long-Term Drought Assessment Across Shaanxi Province, China (2000–2016)

open access: yesRemote Sensing, 2018
Traditional NDVI-Ts space is triangular or trapezoidal, but Liu et al. (2015) discovered that the NDVI-Ts space was bi-parabolic when the study area was covered with low biomass vegetation. Moreover, the numerical value of the indicator was considered in
