A new parsing method based on the semi-Thue system is described. Similar to, but with more efficient implementation than Markov normal algorithms, it can be used for any recursively enumerable language. Despite its computational power, meant to primarily programming and domain-specific languages. It enables a straightforward simulation of number existing algorithms context-free grammars. The li...

Analog beamforming technology is being used to overcome various technical drawbacks of mm-wave wireless communications systems. However, the errors caused by circuit implementations, quantized control, and imperfect isolation between antenna elements result in radiation pattern (RP) distortion performance deterioration. In particular, quantization error mutual coupling cause active reflection c...

We use momentum correlations as physical observables in B → K∗l+l− decays with K polarized to study the long distance contributions. We show that these observables are sensitive to the scenarios of the long distance parametrizations. We find that the T-odd observable is directly related to the nonfactorizable effect in the standard model. PACS 13.20.He, 11.30.Er, 12.40.-y Typeset using REVTEX 1...

Abstract This paper proposes, for the first time, a new radiation pattern synthesis fractal antenna array that combines unique multi-band characteristics of arrays with adaptive beamforming requirements in wireless environment high-jamming power. In this work, method based on discrete cbKalman filter is proposed linear Cantor high performance and low computational requirements. The Kalman filte...

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

antenna structures with low side lobe levels are normally the main goal during antenna design. in this paper, a new method for reduction of radiation pattern side lobe level in phased array antenna with uniform and non-uniform weighting is presented. in this method, by changing the array elements weight or adding several elements, such as slc technique, the pattern with low side lobe level can ...
