Second order statistics provides an efficient representation of a fading channel and plays a major role in the designing and evaluation of the wireless communication systems. This paper presents a channel model framework for the implementation of important second order statistical parameters, in particular the Level Crossing Rate (LCR) and the Average Fade Duration (AFD). In addition to this, o...

‎This paper aims at establishing the existence and uniqueness of solutions for a nonstandard variational-hemivariational inequality. The solutions of this inequality are discussed in a subset $K$ of a reflexive Banach space $X$. Firstly, we prove the existence of solutions in the case of bounded closed and convex subsets. Secondly, we also prove the case when $K$ is compact convex subsets. Fina...

given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

The objective of this study is to control the quality by Thin Layer ChromatographyCloxacillin used in Niamey cityafter carrying out a prospective survey on antibiotics commonly health centers and at same time purchased from street vendors. This aimed investigate eleven samples distributed as following as: five are pharmacies vendors one sample specialty which reference check their active ingred...

The aim of this work was to study the distribution gross forms elements - Ca, Mg, Sr, Ni, Cr, Zn, Mn, Cu, Fe, Pb, Cd, Co, As in soil and plants roadside agrocenosis. Agrocenosis Triticum aestivum L. is located along Federal highway P-404. Sonchus arvensis Cirsium setosum (Willd) Bess. are dominant weed species agrocenosis, have a similar elemental composition. Phytomass these does not accumulat...

in this paper, we introduce and study the notion of precompacttopological generalized groups and some new results are given.

in this paper, using a generalized translation operator, we prove theestimates for the generalized fourier-bessel transform in the space l2 on certainclasses of functions.
