tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...

The exact power distribution of the inter-cell interference is obtained explicitly for cell edge users who are surrounded by circular guard zones. Compared with recent works, the underlying channel model is generalized from Rayleigh fading to a combination of Nakagami fading and Gamma shadowing. In addtion, asymptotic analysis shows that the mean power of intercell interference changes from inf...

According to the recurrent frequency, many levels of points are found such as periodic points, almost weakly quasi-weakly and Banach points. In this paper, we consider symbolic dynamics show existence six refined between recurrence general recurrence. Despite fact that these all null-measure under any invariant measure, further they carry strong topological complexity. Each level is dense in wh...

The momentum distributions of partons in bound nucleons are known to depend significantly on the size of the nucleus. The Fourier transform of the momentum (xBj) distribution measures the overlap between Fock components of the nucleon wave function which differ by a displacement of one parton along the light cone. The magnitude of the overlap thus determines the average range of mobility of the...

In order to combat shadowing and distance losses in a land mobile satellite system, an isdaptive power control (APC) scheme is essential. Such a scheme, implemented on the uplink, ensures that all users’ signals arrive at the base station with equal average power as they move within the satellite spot beam. Because of the lengthy round-trip delay on a satellite link, closed-loop power controll ...

We define continuous and inverse shadowing for flows and prove some properties. In particular, we will prove that an expansive flow without fixed points on a compact metric space which is a shadowing is also a continuous shadowing and hence an inverse shadowing (on a compact manifold without boundary).
