Analysis and convergence of Hermite subdivision schemes

, 2020
Hermite interpolation property is desired in applied and computational mathematics. Hermite and vector subdivision schemes are of interest in CAGD for generating subdivision curves and in computational mathematics for building Hermite wavelets to ...

Measurement invairance and construct validity of the Turkish version of the learner autonomy scale in a sample of high and secondary school students

International Journal of Contemporary Educational Research
The goal of this research is to adapt the 24-item "Learner Autonomy Scale" developed by Sereti and Giossos (2018) in higher education samples into Turkish by examining the psychometric properties of high school and secondary school samples, and to ...

Quantification and Negation in Event Semantics

The Baltic International Yearbook of Cognition, Logic and Communication, 2010
Recently, it has been claimed that event semantics does not go well together with quantification, especially if one rejects syntactic, LF-based approaches to quantifier scope.

Relativistic shifted-l expansion technique for Dirac and Klein-Gordon equations [PDF]

Commun. Theor. Phys. 29 (1998) 587-594, 1999
The shifted-i expansion technique (SLET) is extended to solve for Dirac particle trapped in spherically symmetric scalar and/or 4-vector potentials. A parameter {\lambda}=0,1 is introduced in such a way that one can obtain the Klein-Gordon (KG) bound states from Dirac bound states.

The Inverse and General Inverse of Trapezoidal Fuzzy Numbers with Modified Elementary Row Operations

Mathematics
Trapezoidal positive/negative fuzzy numbers have no single definition; instead, various authors define them in relation to different concepts. This means that arithmetic operations for trapezoidal fuzzy numbers also differ. For the operations of addition,

Abstract non-scalar Volterra difference equations [PDF]

arXiv
In this paper, we investigate the abstract non-scalar Volterra difference equations. We employ the Poisson like transforms to connect the solutions of the abstract non-scalar Volterra integro-differential equations and the abstract non-scalar Volterra difference equations.

Spacetime pq theory for AC and DC electric power systems

Scientific Reports
The 50/60 Hz alternating current (AC) electric power has been the standard and most flexible energy source powering our modern societies for one and a half centuries since the war of the currents: AC versus direct current (DC).

Constant Scalar Curvature Metrics on Connected Sums [PDF]

International Journal of Mathematics and Mathematical Sciences 2003:7 (2003), 405-450., 2001
Let (M,g) be a compact Riemannian manifold with dimension n > 2. The Yamabe problem is to find a metric with constant scalar curvature in the conformal class of g, by minimizing the total scalar curvature. The proof was completed in 1984. Suppose (M',g') and (M'',g'') are compact Riemannian n-manifolds with constant scalar curvature.
