Discrete chaotic systems based on memristors exhibit excellent dynamical properties and are more straightforward to implement in hardware, making them highly suitable for generating cryptographic keystreams. However, most existing memristor-based chaotic systems rely on a single memristor. This paper introduces a novel discrete chaotic system employing dual memristors, named the 3D memristive cubic map with dual discrete memristors (3D-MCM). The 3D-MCM system demonstrates richer and more intricate dynamical behaviors compared to its single-memristor counterparts, as verified through bifurcation diagrams, Lyapunov exponent spectra, and complexity analyses. Notably, the system exhibits coexisting attractors, substantially enhancing its dynamical complexity. Hardware implementation of the 3D-MCM attractors confirms its feasibility for industrial applications. To illustrate the system's potential in encryption tasks, this study integrates the quaternary-based permutation and dynamic emanating diffusion (QPDED-IE) scheme for image encryption with the *** results demonstrate that the QPDED-IE scheme based on the 3D-MCM exhibits strong diffusion and confusion properties, effectively resisting cryptanalytic attacks. © 1991-2012 IEEE.

LC-coupling hybrid active power filter (LC-HAPF) is a cost-effective solution to address power quality issues in low and medium voltage distribution networks. The DC-link voltage controller plays an important role of the LC-HAPF performance. Conventionally, proportional-integral (PI) controller is commonly used for DC-link voltage control due to the ideally zero steady-state error. However, the property of integrator slows down the transient response of DC-link voltage and thus effects the LC-HAPF dynamic performance. In this paper, a nonlinear PID (NPID) controller based on robust exact differentiator (RED) is proposed to improve the transient response of conventional PI controller. First, the parameters of the PID controller are designed by s-domain transfer function analysis. Then, the RED is proposed to replace the linear differentiator, which provides the differential signal fast and accurately. Finally, the advantages of the proposed NPID controller based on RED are verified by simulation results compared with the conventional PI controller. © 2022 IEEE.

In this paper, Fault Tolerant Control (FTC) for fractional-order systems (FOS) has not received as much attention in the literature as it has for standard integer-order systems. This work aims to bridge that gap. We propose a practical approach to fault estimation and fault-tolerant control (FTC) specifically designed for linear (FOS) with sensor failures. Our method leverages fractional exponential stability within the Lyapunov framework and employs the Conformable formulation of fractional derivatives. Notably, the primary contribution of this paper is the first application of the Conformable fractional derivative (CFD) in the context of (FTC). To accurately estimate states and faults, the proposed approach utilizes an observer coupled with a customized adaptation law. To validate our theoretical contributions, we present a detailed simulation of a numerical case study.

A Planar Substrate-Integrated Phased Array With an Over-One-Octave Bandwidth

IEEE Transactions on Antennas and Propagation 2025年

A new wideband planar substrate-integrated phased array is presented in this paper. The array element is based on an open slot excited by a coaxial probe. A T-shaped stripline with shorting pins is employed in each element to achieve a smooth mode conversion from quasi-coaxial to quasi-parallel plate waveguide in a compact manner. In this case, the element supports a full quasi-TEM mode for transmission and radiation. Additionally, the air-filled holes and metal pins are incorporated into the radiating and feeding structures to shift the undesirable resonance to a higher frequency. By combining these techniques, the impedance bandwidth can be extended to more than one octave. The scanning blindness caused by unexpected guided-wave mode during beam scanning along the H-plane is further analyzed in detail, and removed from the desired frequency range by adjusting the corresponding element period and manipulating the guided-wave characteristics. A 10×12-element phased array prototype covering 8-18 GHz (76.9%) is fabricated and tested. Experimental results demonstrate that the proposed phased array achieves a beam scanning of ± 60° in the E-, H- and D-planes, with no scanning blindness occurring across the operating band. © 1963-2012 IEEE.

Physics-Trained Neural Network as Inverse Problem Solver for Potential Fields: An Example of Downward Continuation between Arbitrary Surfaces

arXiv 2025年

作者： Sun, Jing Li, Lu Zhang, Liang Faculty of Electrical Engineering Mathematics and Computer Science Delft University of Technology Netherlands Australia Key Laboratory of Advanced Manufacturing Technology of the Ministry of Education Guizhou University China

Downward continuation is a critical task in potential field processing, including gravity and magnetic fields, which aims to transfer data from one observation surface to another that is closer to the source of the field. Its effectiveness directly impacts the success of detecting and highlighting subsurface anomalous sources. We treat downward continuation as an inverse problem that relies on solving a forward problem defined by the formula for upward continuation, and we propose a new physics-trained deep neural network (DNN)-based solution for this task. We hard-code the upward continuation process into the DNN’s learning framework, where the DNN itself learns to act as the inverse problem solver and can perform downward continuation without ever being shown any ground truth data. We test the proposed method on both synthetic magnetic data and real-world magnetic data from West Antarctica. The preliminary results demonstrate its effectiveness through comparison with selected benchmarks, opening future avenues for the combined use of DNNs and established geophysical theories to address broader potential field inverse problems, such as density and geometry modelling.

Chronic diseases are the leading cause of death and disability worldwide, necessitating early detection and management to mitigate their adverse effects on health and improve quality of life. Leveraging machine learning algorithms has become a prominent approach in predicting the risk of various chronic diseases. These algorithms excel in analyzing complex datasets to identify patterns and risk factors associated with chronic conditions. This study explores the application of two different machine learning algorithms on an open-source dataset to predict the risk of chronic diseases. The outcomes of these implementations are analyzed and discussed in the final section, providing insights into their effectiveness and potential for enhancing chronic disease management.

Quantifying spatial, temporal, angular and spectral structure of effective daylight in perceptually meaningful ways

We present a method to capture the 7-dimensional light field structure, and translate it into perceptually-relevant information. Our spectral cubic illumination method quantifies objective correlates of perceptually relevant diffuse and directed light components, including their variations over time, space, in color and direction, and the environment’s response to sky and sunlight. We applied it "in the wild", capturing how light on a sunny day differs between light and shadow, and how light varies over sunny and cloudy days. We discuss the added value of our method for capturing nuanced lighting effects on scene and object appearance, such as chromatic gradients. © 2022, CC BY.
