Environmental predictions in the marine atmospheric surface layer (MASL) are imperative to optimize X-band radar system performance environments. Evaporation ducts (ED) lead anomalous propagation where characterization of EDs MASL occurs primarily through two methods: in-situ measurements and numerical modeling. This study investigates differences co-located synchronous refractivity estimations...

In this paper, we prove a local limit theorem for the ratio of Poisson distribution to Gaussian with same mean and variance, using only elementary methods (Taylor expansions Stirling's formula). We then apply result derive an upper bound on Le Cam distance between experiments, which gives complete proof sketch provided in unpublished set lecture notes by Pollard (2010), who uses different appro...

In this paper we focus on the creation of general-purpose (as opposed to domain-specific) polarity lexicons in five languages: French, Italian, Dutch, English and Spanish using WordNet propagation. WordNet propagation is a commonly used method to generate these lexicons as it gives high coverage of general purpose language and the semantically rich WordNets where concepts are organized in synon...

Develop an advanced unified hybrid radio propagation model based on parabolic equation and rayoptics methods for both surface-based and airborne applications. This model is named the Advanced Propagation Model (APM) and is the model used in the Advanced Refractive Effects Prediction System (AREPS). Other objectives are to develop a propagation model for earth-satellite geometries suitable for i...

This paper used error back propagation algorithm and regression analysis to analyze and predict untranslated and translated Nigeria Stock Market Price (NSMP). Nigeria stock market prices were collected for the periods of seven hundred and twenty days and grouped into untranslated and translated train, validation and test data. A zero mean unit variance transformation was used to normalize the i...

due to the importance of production and propagation of virus-free potato plants, some of the factors involved in the propagation of potato (plantlet production and virus-free in vitro microtuberization) has been studied. in most reports, adding a mixture of amino acids play an important role in plant tissue culture and development of the explants in many cases increase. this experiment was cond...

We introduce the concept of quasi-intrinsic angular momentum to denote fields for which the mean value of the angular momentum is unaltered by a lateral shift of the rotation axis but the spectrum changes. This property is exemplified by the orbital angular momentum of a beam of light about its propagation direction. We propose an interferometric experiment to measure efficiently the exact angu...

Frequency domain channel propagation measurements in the 800-1000 MHz band have been performed with ground-lying antennas. The range of path-loss exponent and shadowing variance for indoor and outdoor environment were determined. The range of these values roughly agree with those measured for higher elevation antennas. Frequency selectivity of the RF channel was also characterized by means of d...
