Software defined radio (SDR) technology has been attracted due to its flexibility and efficient performance in mobile communication. This paper presents an efficient scheme of multichannel low-IF receiver that improves digital communication quality in the sense of BER performance and computational cost. Simply adding cosine rolloff filters to the conventional multichannel receiver, the proposed...

In this work, we shall present some novel process to measure the similarity between picture fuzzy sets. Firstly, we adopt the concept of intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets and picture fuzzy sets. Secondly, we develop some similarity measures between picture fuzzy sets, such as, cosine similarity measure, weighted cosine similarity measure, set-theoretic similar...

Selfdecomposable variables obtained from series of Laplace (double exponential) are objects this study. We prove that hyperbolic-sine and hyperbolic-cosine in the difference Urbanik classes L2 L3 while generalized logistic variable is at least class L1. Hence some ratios those corresponding selfdecomposable characteristic functions again selfdecomposable.

While the effects of legal and institutional arrangements on political participation are well documented, little attention has been given to the potential participatory effects of one of the United States’ most important electoral laws: constitutionally mandated reapportionment. By severing the ties between constituents and their incumbents, we argue, redistricting raises information costs, lea...

Heavy tailed distributions are worthwhile in modeling heavy data. The researchers often search of such to provide best fit In this article, a new T-X family member called, exponential cosine-X is introduced. A special sub-model the proposed family, cosine Weibull distribution studied detail. Some mathematical properties along with useful series expansion and density functions class obtained. Tw...

37 To compute spatially correct smooth pursuit eye movements, the brain uses both retinal 38 motion and extraretinal signals about the eyes and head in space (Blohm and Lefèvre 2010). 39 However, when smooth eye movements rely solely on memorized target velocity, such as during 40 anticipatory pursuit, it is unknown if this velocity memory also accounts for extraretinal 41 information such as h...

In this paper we bring to bear some new tools from statistical learning on the analysis of roll call data. We present a new data-driven model for roll call voting that is geometric in nature. We construct the model by adapting the “Partition Decoupling Method,” an unsupervised learning technique originally developed for the analysis of families of time series, to produce a multiscale geometric ...

background: topical anesthesia has been widely advocated as an important component of atraumatic administration of intraoral local anesthesia. the aim of this study was to use direct observation of children’s behavioral pain reactions during local anesthetic injection using cotton-roll vibration method compared with routine topical anesthesia. materials and methods: forty-eight children partici...

Time-averaged series of granulation images are analysed using COLIBRI, a purpose-adapted version of a code originally developed to detect straight or curvilinear features in aerospace images. The algorithm of image processing utilises a nonparametric statistical criterion that identifies a straight-line segment as a linear feature (lineament) if the photospheric brightness at a certain distance...
