This paper studies the nonlinear vibration analysis of a simply supported Euler-Bernoulli beam resting on a nonlinear elastic foundation under compressive axial load using nonlinear normal modes concept in the case of three-to-one (3:1) internal resonance. The beam’s governing nonlinear PDE of motion and also its boundary conditions are derived and then solved using the method of Multiple Time ...

We consider hidden Markov processes in discrete time with a finite state space X and a general observation or read-out space Y , which is assumed to be a Polish space. It is well-known that in the statistical analysis of HMMs the so-called predictive filter plays a fundamental role. A useful result establishing the exponential stability of the predictive filter with respect to perturbations of ...

Computing the gaussian likelihood for a nonstationary state-space model is a difficult problem which has been tackled by the literature using two main strategies: data transformation and diffuse likelihood. The data transformation approach is cumbersome, as it requires nonstandard filtering. On the other hand, in some nontrivial cases the diffuse likelihood value depends on the scale of the dif...

Although quite many qualitative studies on painting in Alzheimer’s disease (AD) have been conducted, there is a lack of quantitative studies, examining the ability to paint in people with AD in relation to disease stages, and to what extent instructions are associated with actual performance. The present study aimed at investigating the capability to paint among nonartist AD participants (N = 1...

smart home is composed of several controllers with different plants in control. if each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. the function of different controller system may has conflict in some condition...

In our paper " Can disorder induce a finite thermal conductivity in 1D lattices? " (Phys. we have pointed out two important things. First, the disorder can induce a finite thermal conductivity in lower temperature regime. Second, our numerical calculations with Noo´se-Hoover thermostats shown that a unique nonequilibrium stationary state may not exist in a disorder harmonic chain. In his commen...

Joint ground states of two directed polymers in a random medium are investigated. Using exact min-cost flow optimization the true two-line ground-state is compared with the single line ground state plus its first excited state. It is found that these two-line configurations are (for almost all disorder configurations) distinct implying that the true two-line ground-state is non-separable, even ...

Veriest is an automatic translator that converts synthesizable Verilog designs into the synchronous language Esterel. The translation into a synchronous language can expose hidden flaws in the original design, including subtle race conditions. In addition, the extensive libraries of verified Verilog designs can now be reused in synchronous designs. Verilog and Esterel have different models and ...
