Abstract The maximum length binary sequence (MLBS) is widely used as a broadband pseudo-random noise excitation signal, for example, for system identification. Although its properties have been known for decades, misleading or inaccurate statements c

Introduction. The main attention is paid to the need to take into account estimates of rounding errors when solving problems of transcomputational complexity. Among such tasks, one can highlight the tasks of calculating systems of linear algebraic eq

Designing an efficient muffler for single-cylinder IC engines is not an easy task due to the limitation in designing a large muffler and the possibility of engine suffocation. In this regard, this research aims to experimentally investigate the feasi

Abstract This paper introduces the concept of complex quadratic Diophantine fuzzy sets (CQDFS) which serves as a robust framework for effectively dealing with uncertainty within decision-making challenges. The study comprehensively explores the prope

In this paper, we propose a parametric OFDM transceiver for wireless communication encryption. One of the major contributions of this work is the intrinsic encryption nature of the proposed system, since it is a completely new idea and philosophica

Magnet-free acrlongpl vppm are competitive alternatives in electric vehicles where torque-speed operating region, reliability, cost, and energy efficiency are key metrics. However, their modeling and control have so far relied on existing fixed-phase

This research work extends the hyperchaotic 4D Chen system into the fractional-order domain to carry out image encryption over 3 stages. For the first encryption stage, the discrete Fourier transform (DFT) of the numerical solution of the fractional-

By assuming a type of balance for length ℓ=87\ell =87 and nontrivial subgroups of multiplier groups of Legendre pairs (LPs) for length ℓ=85\ell =85, we find LPs of these lengths. We then study the power spectral density (PSD) values of mm compres
