Function theory for a beltrami algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
Complex functions are investigated which are solutions of an elliptic system of partial differential equations associated with a real parameter function.

The Cosmological Spacetime [PDF]

open access: yes, 2009
We present here the transformations required to recast the Robertson-Walker metric and Friedmann-Robertson-Walker equations in terms of observer-dependent coordinates for several commonly assumed cosmologies.

Concrete-Filled-Large Deformable FRP Tubular Columns under Axial Compressive Loading

open access: yesFibers, 2015
The behavior of concrete-filled fiber tubes (CFFT) polymers under axial compressive loading was investigated. Unlike the traditional fiber reinforced polymers (FRP) such as carbon, glass, aramid, etc., the FRP tubes in this study were designed using ...

Towards Possible Laminar Channels through Turbulent Atmospheres in a Multifractal Paradigm

open access: yesAtmosphere, 2021
In this paper, developments are made towards simulating complex atmospheric behavior using turbulent energy cascade staging models developed through scale relativity theories.

General Relativity Constraints the Proper Times and Predicts the Frozen Stars Instead of the Black Holes

open access: yes, 2007
In a static gravitational field an intersection of a worldline by a global hypersurface of simultaneity t=const gives an invariant constraint relating the proper time of this event by t.

Dilation Equations with Exponential Decay Coefficients

open access: yesJournal of Mathematical Analysis and Applications, 1999
Dilation equations with finitely many nonzero coefficients have been extensively studied because of their connection with compactly supported wavelets . However, some properties required in applications are not compatible with the compactness of the support. For example, \textit{X.-G. Xia} [J. Fourier Anal. Appl. 1, No. 2, 193-199 (1994; MR 96i:42026)]

Bonded Concrete Overlays: A Brief Discussion on Restrained Shrinkage Deformations and Their Prediction Models

open access: yesNordic Concrete Research, 2019
Bonded concrete overlays (BCO) on bridge decks are beneficial solutions due to their superior properties as compared to the typical asphalt pavement. A significant number of overlays suffer however, from occurrence of cracks and delamination due to poor ...

Valiron and Abel equations for holomorphic self-maps of the polydisc

open access: yes, 2016
We introduce a notion of hyperbolicity and parabolicity for a holomorphic self-map $f: \Delta^N \to \Delta^N$ of the polydisc which does not admit fixed points in $\Delta^N$.

Methods of solving dilation equations [PDF]

open access: yes, 1992
A wavelet basis is an orthonormal basis for L2(ℜ), the space of squareintegrable functions on the real line, of the form {gnkn,k∈z, where gnk (t) = 2n/2 g (2nt−k) and g is a single fixed function, the wavelet Each multiresolution analysis for L2(ℜ) determines such a basis. To find a multiresolution analysis, one can begin with a dilation equation f (t)

A Class of Dilation Integral Equations

open access: yesJournal of Mathematics Research, 2012
We present a class of dilation integral equations. The equations in this class depend on a dilation parameter $a\in\mathbb{R}.$ The existence of non trivial solutions in $L^1(\mathbb{R})$ is studied as a function of the dilation parameter. The main result establishes the non existence of these solutions for $|a| 1,$ and sufficient conditions for these ...
