Cosmic Expansion As a Virtual Problem

Authors: Hans Detlef Hüttenbach
Comments: 5 Pages.

The fact that a red shift of galaxies is observed to increase with the galaxies approaching the cosmic horizon is taken as plain evidence that the universe is acceleratedly expanding, hopefully perpetually. That implication does however not take into account the gravitational effects of the cosmic horizon on the universe; the cosmic horizon is the center of mass of our universe, and taking this into account, a very different picture of the state of our universe results: Based on [1] it is shown that the observed red shift, implies a huge deceleration of the universe, already. Whether the cosmos is currently before, at, or after the turn from expansion to collapse, this could only be answered by repeated red shift measurements over the next decades.

Unified Field Theory Chaykin

Authors: Andrey Chaykin
Comments: 6 Pages.

In this paper, based on the super fluid substance (vacuum liquid) is identical with the equations of the electromagnetic field and gravitational field. These differential equations are corrected by the author equations of electrodynamics Maxwell. Electrodynamics 1. Excluded vortex electric field, the electric field is always potentially. 2. Time-varying magnetic field is interpreted as a density charge displacement and added to the real density of the charges. Gravitodynamics. For the successful application of modified equations of electrodynamics to gravity, enough gravitational mass to be considered as a gravitational charge, having the same dimensionality as the electric charge. For that weight multiply on the gravitational constant of Newton in degree 1/2. Gravity currents are conventional mechanical pulses multiplied by this factor also leads to a vortex gravitational fieldes, as in electrodynamics and with the same consequences.

Expanding Newton Mechanics with Neutrosophy and Quadstage Method ──New Newton Mechanics Taking Law of Conservation of Energy as Unique Source Law

Authors: Fu Yuhua
Comments: 78 Pages.

Neutrosophy is a new branch of philosophy, and "Quad-stage" (Four stages) is the expansion of Hegel’s triad thesis, antithesis, synthesis of development.Applying Neutrosophy and "Quad-stage" method, the purposes of this paper are expanding Newton Mechanics and making it become New Newton Mechanics (NNW)taking law of conservation of energy as unique source law.

Assessing the Performance of Data Fusion Algorithms Using Human Response Models

Authors: Donald J. Bucci
Comments: 175 Pages.

There is ongoing interest in designing data fusion systems that make use of human opinions (i.e.,\soft" data) alongside readings from various sensors that use mechanical, electromagnetic, optical,and acoustic transducers (i.e., \hard" data). One of the major challenges in the development of these hard/soft fusion systems is to determine accurately and flexibly the impact of human responses on the performance of the fusion operator.

HFVS:Arbitrary High Order Flux Vector Splitting Method

Authors: Yibing Chen, Song Jiang, Na Liu
Comments: 22 Pages.

In this paper, a new scheme of arbitrary high order accuracy in both space and time is proposed to solve hyperbolic conservative laws. Based on the idea of °ux vector splitting(FVS) scheme, we split all the space and time derivatives in the Taylor expansion of the numerical °ux into two parts: one part with positive eigenvalues, another part with negative eigenvalues. According to a Lax-Wendro® procedure, all the time derivatives are then replaced by space derivatives. And the space derivatives is calculated by WENO reconstruction polynomial. One of the most important advantages of this new scheme is easy to implement.In addition, it should be pointed out, the procedure of calculating the space and time derivatives in numerical °ux can be used as a building block to extend the current ¯rst order schemes to very high order accuracy in both space and time. Numerous numerical tests for linear and nonlinear hyperbolic conservative laws demonstrate that new scheme is robust and can be high order accuracy in both space and time.

View on the Triple Torus Hologram for the Universe.

Authors: Dan Visser
Comments: 1 Page.

This paper is an additional short topic to my former paper In the paper a visualization is given of the rotating Triple Torus Hologram (rTTH), which emerges from my Double Torus Theory (DTT), and which comprehends a rotating Time Torus Universe (rTTU) that performs three ‘tori’, in which the recalculation of the physical reality happens.

The Bianchi Identities in Weyl Space

Authors: William O. Straub
Comments: 3 Pages. Fixed typo in Equation 4.3

As far as the writer is aware, the Bianchi identities associated with a Weyl space have never been presented. That space was discovered by the noted German mathematical physicist Hermann Weyl in 1918, and represented the geometry underlying a tantalizing theory that appeared to successfully unify the gravitational and electromagnetic fields. One of theory’s problems involved one form of the Bianchi identities, which in Riemannian space are used to derive the divergenceless Einstein tensor. Such a derivation is generally not applicable in a non-Riemannian geometry like Weyl’s, in which the covariant derivative of the metric tensor is non-zero. But it turns out that such a derivation is not only possible but straightforward, with a result that hints at a fundamental relationship between Weyl’s geometry and electromagnetism.

The Invisible Fractal

Authors: José Salvador Ruiz Fargueta
Comments: 3 Pages.

In spaces where some of its dimensions are insignificant (compacted) compared to others, can happen a curious phenomenon that the magnitude of the scalar characteristic of fractal becomes dependent on the inverse distance. This means that the observed fractal is "dense" at small distances and “vacuum”, or invisible, at large distances. En espacios donde algunas de sus dimensiones son despreciables (compactadas) respecto a otras, puede ocurrir un curioso fenómeno por el que la magnitud del escalar característico del fractal pasa a depender del inverso de la distancia. Esto significa que el fractal se observa “denso” a pequeñas distancias y vacuo en las grandes distancias.
