Elementary test for non-classicality based on measurements of position and momentum
, 2015 We generalise a non-classicality test described by Kot et al. [Phys. Rev. Lett. 108, 233601 (2010)], which can be used to rule out any classical description of a physical system.

AIChE Journal, EarlyView.ABSTRACT Flexibility is a crucial characteristic of industrial systems that face increasing volatilities and is therefore essential to ensure feasible operation under uncertainty. Flexibility is often closely tied to the design of a system, and careful consideration must be taken to understand the trade‐off between design cost and operational ...

Estimates of the error of interval quadrature formulas on some classes of differentiable functions
Researches in Mathematics, 2020 The exact value of error of interval quadrature formulas $$\int_0^{2\pi}f(t)dt -\frac{\pi}{nh}\sum_{k=0}^{n-1}\int_{-h}^hf(t+\frac {2k\pi}{n})dt = R_n(f;\vec{c_0};\vec{x_0};h)$$ obtained for the classes $W^rH^{\omega} (r=1,2,...)$ of differentiable ...

Energy Technology, EarlyView.Advanced virtual impedance control integrating multiple second‐order generalized integrator (SOGI) variants—SOGI, ESOGI, MSOGI, and DSOGI—enhances power and harmonic sharing accuracy in islanded microgrids. The comparative study quantifies performance–complexity trade‐offs, demonstrating up to 65% total harmonic distortion (THD) reduction and improved ...

Journal of Approximation Theory, 1984 Quadrature formulae for splines with equispaced knots are developed in this paper. For special classes of splines, some simple explicit expressions for the weights in the quadrature formulae in terms of the zeros of the Euler-Frobenius polynomials are given and it is shown that these weights are positive. Some quadrature formulae are derived.

Energy Science &Engineering, EarlyView.This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

Euler-Maclaurin type optimal formulas for numerical integration in Sobolev space
Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2020 In the present paper the problem of construction of optimal quadrature formulas in the sense of Sard in the space L2(m)(0,1) is considered. Here the quadrature sum consists of values of the integrand at nodes and values of the first and the third ...
