the present paper investigates the potential application of graphene sheets with attached nanoparticles as resonant sensors by introducing a nonlocal shear deformation plate model. to take into account an elastic connection between the nanoplate and the attached nanoparticle, the nanoparticle is considered as a mass-spring system. then, a combination of pseudo-spectral and integral quadrature m...

There is evidence that the conventional, continuous underlying function model of financial asset pricing can be improved by adding a discontinuous jump component. Barndorff-Nielsen and Shephard (2004) propose a method of detecting these jumps that compares different estimators of quadratic variation. This paper applies that detection method to the common stock of Altria Group, Inc. and attempts...

In this paper we analyze asset returns models with diffusion part and jumps in returns with stochastic volatility either from diffusion or pure jump part. We consider different specifications for the pure jump part including compound Poisson, Variance Gamma and Levy α-stable jumps. Monte Carlo Markov chain algorithm is constructed to estimate models with latent Variance Gamma and Levy α−stable ...

In order to supply a gap of current resonance vibration and STFT demodulation method applied to rolling bearing fault feature extraction of city rail vehicle, a fault diagnosis method for rolling bearing is presented, which is based on the integration of improved wavelet packet, frequency energy analysis and Hilbert marginal spectrum. When faults occur in rolling bearing, the energy of the roll...

this study aimed at investigating the effect of bcaas consumption on wrestlers' creatine kinase (ck) activity in a three-month depth jump exercise. for this purpose, 22 male wrestlers from zanjan province (age 21.54±3.52 yr, weight 66.18±3.76 kg, height 168.36±2.41 cm, bmi 23.34±1.97 kg/m2) were randomly selected and divided into two groups. during the mentioned period, both groups had the...

Uncertain differential equation with jumps, as a crucial tool to deal with a discontinuous uncertain system, is a type of differential equation driven by both canonical Liu process and uncertain renewal process. So far, a concept of stability in measure for an uncertain differential equation with jumps has been proposed. As a supplement, this paper proposes a concept of almost sure stability fo...
