APPROXIMATE OPTIMAL CONTROL OF LINEAR TIME-DELAY SYSTEMS VIA HAAR WAVELETS [PDF]
Journal of Engineering Science and Technology, 2016 In this paper, Haar wavelet benefits are applied to the optimal control of linear time-delay systems. A discretized form of optimal control problem at collocation points based on some useful properties of Haar wavelets transforms original problem into a ...

Decoupling with random diagonal unitaries [PDF]
, 2017 We investigate decoupling, one of the most important primitives in quantum Shannon theory, by replacing the uniformly distributed random unitaries commonly used to achieve the protocol, with repeated applications of random unitaries diagonal in the Pauli-

Ergodicity criteria for non-expanding transformations of 2-adic spheres
, 2012 In the paper, we obtain necessary and sufficient conditions for ergodicity (with respect to the normalized Haar measure) of discrete dynamical systems $$ on 2-adic spheres $\mathbf S_{2^{-r}}(a)$ of radius $2^{-r}$, $r\ge 1$, centered at some point $a ...

Estimation of Delay Time in Linear Dynamic Systems Using Wavelets [PDF]
المجلة العراقية للعلوم الاحصائيةThis research explores the use of wavelets in estimating delay time in stochastic linear dynamic systems, as delay time plays a crucial role in diagnosing the system by determining the time interval between inputs and outputs.

Generalized Euler Angle Paramterization for SU(N)
, 2002 In a previous paper (math-ph/0202002) an Euler angle parameterization for SU(4) was given. Here we present the derivation of a generalized Euler angle parameterization for SU(N).

Metric Structure of the Space of Two-Qubit Gates, Perfect Entanglers and Quantum Control
Entropy, 2013 We derive expressions for the invariant length element and measure for the simple compact Lie group SU(4) in a coordinate system particularly suitable for treating entanglement in quantum information processing.

Local witness for bipartite quantum discord
, 2013 Recently, we proposed a method for the local detection of quantum correlations on the basis of local measurements and state tomography at different instances in time [Phys. Rev. Lett. 107, 180402 (2011)].

Frame Set for Gabor Systems with Haar Window
Applied and Computational Harmonic Analysis, 2023 We show the full structure of the frame set for the Gabor system $\mathcal{G}(g;α,β):=\{e^{-2πi mβ\cdot}g(\cdot-nα):m,n\in\Bbb Z\}$ with the window being the Haar function $g=-χ_{[-1/2,0)}+χ_{[0,1/2)}$. The strategy of this paper is to introduce the piecewise linear transformation $\mathcal{M}$ on the unit circle, and to provide a complete ...
