this paper presents the high order frequency-amplitude relationship for nonlinear transversely vibrating beams with odd and even nonlinearities using homotopy perturbation method with an auxiliary term (hpmat). the governing equations of vibrating buckled beam, beam carrying an intermediate lumped mass and quintic nonlinear beam are investigated to exhibit the reliability and ability of the pro...

The Rabin-Miller primality test is a probabilistic test which can be found in several algebraic computing systems (such as Pari, Maple, ScratchPad) because it is very easy to implement and, with a reasonable amount of computing, indicates whether a number is composite or "probably prime" with a very low probability of error. In this paper, we compute composite numbers which are strong pseudopri...

The colliding heavy ions create extremely strong magnetic and electric fields that significantly affect the evolution of produced quark-gluon plasma (QGP). knowledge these is essential for establishing role topological fluctuations in QGP through chiral effect related anomaly-induced phenomena. In this talk, we describe our work on framework hydrodynamics supplemented, a perturbative fashion, b...

In this paper, we perform a detailed study of the spectral response of the gold U-shaped nano-structures for different geometrical parameters and polarizations in order to obtain significant localization factor in the wavelength 1.55 μm. The obtained near-field distribution of electric fields reveals that resonances in these nano-structures correspond to the even and odd plasmonic modes dependi...

We define a diamonded odd cycle to be an odd cycle C with exactly two chords and either a) C has length five and the two chords are non-crossing; or b) C has length greater than five and has chords (x,y) and (x,z) with (y,z) an edge of C and there exists a node w not on C adjacent to y and C, but not x. In this paper, we show that given a diamonded odd cycle-free graph G, G is perfect if and on...

The local ordering, morphology, and dynamics of aromatic cores and flexible alkyl spacers were analyzed for a homologous series of main-chain polymeric liquid crystals. 13C NMR experiments showed that the nematic ordering achieved by these synthetic polymers was retained into the solid state if their quenchings occur while remaining within the strong NMR magnetic field. The degree of orientatio...

drought is common across the south of iran, especially in darab district. accordingly, studying the economic aspects of deficit irrigation technique – that is one of the basic strategies in water saving for reducing water use of cotton as one of the main agricultural products in darab district is essential. in order to investigate the deficit irrigation technique and to determine its economic t...

In this paper, we find a strong new restriction on the structure of CI-groups. We show that, if R is generalised dihedral group and CI-group, then for every odd prime p Sylow p-subgroup has order p, or 9. Consequently, any CI-group with quotient same restriction, that
