Elastic Behavior of Functionally Graded Two Tangled Circles Chamber [PDF]

Journal of Applied and Computational Mechanics, 2019
This paper presents the numerical elastic solution for a real problem, functionally graded chamber of hydraulic gear pumps under internal pressure. Because of the similarity and complexity for the considering geometry, a bipolar cylindrical coordinate ...

On de-Sitter Geometry in Cosmic Void Statistics [PDF]

, 2013
Starting from the geometrical concept of a 4-dimensional de-Sitter configuration of spheres in Euclidean 3-space and modelling voids in the Universe as spheres, we show that a uniform distribution over this configuration space implies a power-law for the

A Comparative Study of Fractal Geometry Layouts in Organizing the Architecture and Ornamentation of Nasir Al-Mulk Mosque [PDF]

نگره
Iranian geometry is the result of the architect's view of philosophical aspects, natural sciences, and applied mathematics. The architecture and application of ornamentation, derived from nature’s geometry patterns in organizing all kinds of Karbandies ...

Liquid jet eruption from hollow relaxation [PDF]

, 2013
A cavity hollowed out on a free liquid surface is relaxing, forming an intense liquid jet. Using a model experiment where a short air pulse sculpts an initial large crater, we depict the different stages in the gravitational cavity collapse and in the ...

Geometric transformations in school geometry

Lietuvos Matematikos Rinkinys
The study delves into the learning progression for school geometry based on transformations proposed by Hung-Hsi Wu. Plane transformations – translations, reflections, rotations, and dilations – are considered.

Semiclassical Strings in Supergravity PFT [PDF]

, 2014
Puff Field Theory (PFT) is an example of a non-local field theory which arises from a novel embedding of D-branes in Melvin universe. We study several rotating and pulsating string solutions of the F-string equations of motion in the supergravity dual of

Modeling meander morphodynamics over self-formed heterogeneous floodplains [PDF]

, 2017
This work addresses the signatures embedded in the planform geometry of meandering rivers consequent to the formation of floodplain heterogeneities as the river bends migrate.

Scalar fields on SL(2,R) and H^2 x R geometric spacetimes and linear perturbations

, 2004
Using appropriate harmonics, we study the future asymptotic behavior of massless scalar fields on a class of cosmological vacuum spacetimes. The spatial manifold is assumed to be a circle bundle over a higher genus surface with a locally homogeneous ...

A geometric framework for modelling similarity search

, 1999
The aim of this paper is to propose a geometric framework for modelling similarity search in large and multidimensional data spaces of general nature, which seems to be flexible enough to address such issues as analysis of complexity, indexability, and ...
