Man only progresses by slowly elaborating from age to age the essence and the totality of a universe deposited within him. The Holographic Principle holds the information in any region of space and time exists on the surface of that region. Layers of the holographic, universal " now " go from the inception of the universe to the present. Universal Consciousness is the timeless source of actuali...

Space–time can be understood as some kind of space–time foam of fluctuating bubbles or loops which are expected to be an outcome of a theory of quantum gravity. One recently discussed model for this kind of space–time fluctuations is the holographic principle which allows to deduce the structure of these fluctuations. We review and discuss two scenarios which rely on the holographic principle l...

A broadband T/R frond-end of active holographic imaging system is presented. Compact autodyne mode circuit structure front-end is adopted to achieve higher signal to noise ratio and higher reliability, which is beneficial to the after-end imagining. The factors that influence the dynamic range and the transverse resolution ratio of holographic imaging system have been analyzed. Wide-band oscill...

A fiber optics image-transferring element is nonisoplanatic over a surface region containing only a few fundamental resolution elements, and no meaningful or consistent evaluation of a fiber optics image can be made by examining such a nonisoplanatic region. A holographic scheme offers a solution to the problem of fiber optics image evaluation based upon examination of a nonisoplanatic region. ...

Holographic interferometry has been used to plot graphs of the phototropic and geotropic bending undergone by a mature Stapelia variegata Linn over a 5-minute period. The holographic interferometric technique is shown to have the advantage of measuring displacements at least as small as 0.16 micrometers which permits observation of extremely slow plant motions over time periods of a few minutes...

Based on a vector wave theory of volume holograms, dependence of holographic reconstruction on the polarization states of the writing and reading beams is discussed. It is found that under paraxial approximation the circular polarization holograms provide a better distinction of the reading beams. Characteristics of recording polarization holograms in thick phenanthrenequinone-doped poly(methyl...

In this paper, we investigate the holographic dark energy model with interaction between dark energy and dark matter, from the statefinder viewpoint. We plot the trajectories of the interacting holographic dark energy model for different interaction cases as well as for different values of the parameter c in the statefinder-plane. The statefinder diagrams characterize the properties of the holo...

We study the correspondence between field theoretic and holographic dark energy density of the universe with the modified Chaplygin gas (MCG) respectively both in a flat and non-flat FRW universe. We present an equivalent representation of the MCG with a homogeneous minimally coupled scalar field by constructing the corresponding potential. A new scalar field potential is obtained here which is...

Holographic algorithms are a novel approach to design polynomial time computations using linear superpositions. Most holographic algorithms are designed with basis vectors of dimension 2. Recently Valiant showed that a basis of dimension 4 can be used to solve in P an interesting (restrictive SAT) counting problem mod 7. This problem without modulo 7 is #P-complete, and counting mod 2 is NP-har...

The authors present a computational model that builds a holographic lexicon representing both word meaning and word order from unsupervised experience with natural language. The model uses simple convolution and superposition mechanisms (cf. B. B. Murdock, 1982) to learn distributed holographic representations for words. The structure of the resulting lexicon can account for empirical data from...
