Attendance System using Haar Cascade Approach

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: The participation framework is utilized to track and screen whether an understudy goes to a class. There are various kinds of participation frameworks like Biometric-based, Radio recurrence card-based, face acknowledgment based and old paper-based participation framework. Out of them every one of the, a Face acknowledgment based participation

The topological spaces that support Haar systems [PDF]

open access: yesProceedings of the American Mathematical Society, 1985
A topological space X X supports a nontrivial Haar system if and only if there is a continuous one-to-one map of X X into the unit circle. This gives an elementary proof of Mairhuber’s classical theorem for compact X X . It answers a 1960 question asked by R. R.

Feedback Control Method Using Haar Wavelet Operational Matrices for Solving Optimal Control Problems

open access: yesAbstract and Applied Analysis, 2013
Most of the direct methods solve optimal control problems with nonlinear programming solver. In this paper we propose a novel feedback control method for solving for solving affine control system, with quadratic cost functional, which makes use of only ...

Quantum Complexity and Chaos in Many-Qudit Doped Clifford Circuits [PDF]

open access: yesQuantum
We investigate the emergence of quantum complexity and chaos in doped Clifford circuits acting on qudits of odd prime dimension $d$. Using doped Clifford Weingarten calculus and a replica tensor network formalism, we derive exact results and perform ...
