A robust lp‐norm localization of moving targets in distributed multiple‐input multiple‐output radar with measurement outliers

IET Radar, Sonar &Navigation, Volume 17, Issue 11, Page 1728-1742, November 2023., 2023
A robust algebraic algorithm based on lp ${l}_{p}$‐norm minimisation and IRLS is developed. The simulation results demonstrated that the localisation RMSE and bias of the existing algorithms increased dramatically in impulse measurement noise. In contrast, the localisation RMSE and bias of the developed algorithm were significantly lower at different ...

Information‐theoretic model of induced technical change: Theory and empirics

Metroeconomica, Volume 74, Issue 1, Page 2-39, February 2023., 2023
Abstract The paper develops an information‐theoretic model of induced technical change where payoff‐maximizing agents are exposed to a positive degree of uncertainty when adopting new technology due to unobserved cost factors. The derived equilibrium of the model comes in the form of a non‐degenerate probability distribution that defines the distance ...

Analysis of Eavesdropping Region in Hybrid mmWave‐Microwave Wireless Systems

Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023
Hybrid communication systems, where millimeter‐wave (mmWave) links coexist with microwave links, have been an essential component in the fifth‐generation (5G) wireless networks. Nevertheless, the open feature of the wireless medium makes hybrid systems vulnerable to eavesdropping attacks.

A Comparison of Six Transport Models of the MADE‐1 Experiment Implemented With Different Types of Hydraulic Data

Water Resources Research, Volume 57, Issue 5, May 2021., 2021
Abstract Six conceptually different transport models were applied to the macrodispersion experiment (MADE)‐1 field tracer experiment as a first major attempt for model comparison. The objective was to show that complex mass distributions in heterogeneous aquifers can be predicted without calibration of transport parameters, solely making use of ...

k ‐Fractional Variants of Hermite‐Mercer‐Type Inequalities via s‐Convexity with Applications

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
This article is aimed at studying novel generalizations of Hermite‐Mercer‐type inequalities within the Riemann‐Liouville k‐fractional integral operators by employing s‐convex functions. Two new auxiliary results are derived to govern the novel fractional variants of Hadamard‐Mercer‐type inequalities for differentiable mapping Ψ whose derivatives in the

Secrecy‐Capacity‐Optimization‐Artificial‐Noise in Large‐Scale MIMO: Ergodic Lower Bound on Secrecy Capacity and Optimal Power Allocation

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
The security of wireless information transmission in large‐scale multi‐input and multioutput (MIMO) is the focus of research in wireless communication. Recently, a new artificial noise—SCO‐AN which shows no orthogonality to the channel, is proposed to overcome the shortcomings of traditional artificial noise.

Euler‐Type Integral Operator Involving S‐Function

Abstract and Applied Analysis, Volume 2020, Issue 1, 2020., 2020
The object of the present paper is to establish some interested theorems on Euler‐type integrals involving S‐function, which is defined by Saxena and Daiya. Further, we reduce some special cases involving various known functions like the k‐Mittag‐Leffler function, K‐function, and M‐series.

Degenerate Analogues of Euler Zeta, Digamma, and Polygamma Functions

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
In recent years, much attention has been paid to the role of degenerate versions of special functions and polynomials in mathematical physics and engineering. In the present paper, we introduce a degenerate Euler zeta function, a degenerate digamma function, and a degenerate polygamma function.

Several Turán‐Type Inequalities for the Generalized Mittag‐Leffler Function

Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
In this paper, several Turán‐type inequalities for the more generalized Mittag‐Leffler function are proved. In addition, we also gave affirmative answers to two open problems posed by Mehrez and Sitnik.

Time series models with an EGB2 conditional distribution [PDF]

, 2013
A time series model in which the signal is buried in noise that is non-Gaussian may throw up observations that, when judged by the Gaussian yardstick, are outliers.
