As a quantum theory of gravity, Matrix theory should provide a realization of the holographic principle, in the sense that a holographic theory should contain one binary degree of freedom per Planck area. We present evidence that Bekenstein’s entropy bound, which is related to area differences, is manifest in the plane wave matrix model. If holography is implemented in this way, we predict cros...

a study with travel cost method (tcm) was performed to evaluate ecotourism demand of lake belonging to karoon 3 dam. for this purpose, 220 clawson questionnaires at highest demand time (february to may 2008) were completed. results of this investigation showed that forecasting outdoor recreational value of karoon 3 dam limits is equal to 2,879,550,000 rials at month, during study. in order to p...
There is considered square billet stretching in a cylindrical matrix. To ensure minimization of an inequality effect ends the matrix there was used leading-in profile area. The investigation impact upon geometry products manufactured carried out. efficient geometrical ratios tool allowing achievement lesser parts end area are revealed.
Serial matrices are a preferred choice for building diffusion layers of lightweight block ciphers as one just needs to implement the last row of such a matrix. In this work we analyze a new class of serial matrices which are the lightest possible 4 × 4 serial matrix that can be used to build diffusion layers. With this new matrix we show that block ciphers like LED can be implemented with a red...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
