LIMITING PROFILE OF AXISYMMETRIC INDENTER DUE TO THE INITIALLY DISPLACED DUAL-MOTION FRETTING WEAR
Recently the final worn shape of elastic indenters due to fretting wear was analytically solved using the method of dimensionality reduction. In this paper we extend this model to dual-motion fretting wear and take into account that the indenter is ...

Non-oscillation of periodic half-linear equations in the critical case
Recently, it was shown that the Euler type half-linear differential equations $$ [ r (t) t^{p-1}\Phi(x')]' + \frac{s (t)}{ t \log^p t} \Phi(x) = 0 $$ with periodic coefficients r and s are conditionally oscillatory and the critical oscillation ...

Experimental study on the slip evolution of planar fractures subjected to cyclic normal stress
The frictional rupture mechanisms of rock discontinuities considering the dynamic load disturbance still remain unclear. This paper investigates the transitional behaviors of slip events happened on a planar granite fracture under cyclic normal stress ...

Load changes in a microgrid comprising diesel generators and wind turbines cause oscillations in system frequency. In this paper, an analytical model that takes wind generator speed deviation into account is proposed to evaluate the oscillation frequency

Oscillation Criteria of Certain Third-Order Differential Equation with Piecewise Constant Argument
We study the oscillation and asymptotic behavior of third-order nonlinear delay differential equation with piecewise constant argument of the form (r2(t)(r1(t)x'(t))')'+p(t)x'(t)+f(t,x([t]))=0. We establish several sufficient conditions which insure that

Summer snow extent heralding of the winter North Atlantic Oscillation [PDF]
[1] Winter climate over the North Atlantic and European sector is modulated by the North Atlantic Oscillation (NAO). We find that the summer extent of snow cover over northern North America and northern Eurasia is linked significantly (p < 0.01) to the ...

This paper investigates the oscillatory behavior of first-order linear differential and difference equations with several delays. The main objective is to determine whether classical liminf-type oscillation conditions for single-delay equations can be ...

Oscillation of generalized Riemann–Weber type differential equations with delay
In this study, we investigate the oscillatory behavior of a generalized Riemann–Weber type differential equation, incorporating a logarithmically varying perturbation term and a time delay.
