Most of research works discuss the identification problem of Wiener model parameters without considering the colored noise of the actual industry process and lacking the physical basis. In order to solve the problem, a Wiener model identification algorithm based on separable signal sources is proposed in this paper to identify the Wiener nonlinear subsystem with output noise interference. The separable signals are used to separate the dynamic linear subsystem from static nonlinear subsystem. Then, the correlation analysis approach is adopted by using a set of Gaussian signals to identify the parameters of dynamic linear subsystem. Further, the parameter identification algorithm based on recursive generalized extended least square method is proposed to estimate the parameter of the dynamic nonlinear subsystem and the noise subsystem by using a set of binary signals as the input signals. © 2019 IEEE.

F-MMD-DBA: Frobenius-norm Maximum Mean Discrepancy for domain bi-classifier adversarial

Pattern Recognition Letters 2025年

Unsupervised domain bi-classifier adversarial approaches are promising methods to deal with domain shifts. Combined with metric learning, they significantly reduce ambiguous predictions. However, they have challenges in the leverage of global information, the relationships between subdomains, the consistency of feature representation, and the conflict due to the bi-classifier adversarial paradigm and usage of local information. Here, we propose Frobenius-norm Maximum Mean Discrepancy for Domain Bi-classifier Adversarial (F-MMD-DBA) to alleviate these by imposing and integrating global and local constraints. Maximum Mean Discrepancy, as the global constraint, can utilize global information. As the local constraint, Frobenius-norm focuses on the relationship of subdomains and avoids conflict. The integration of global and local constraints increases the consistency of feature representation. Ours has greatly improved the accuracy of digits classification and object recognition tasks. The code will be available at https://***/JackyDeepLearning/F-MMD-DBA .

This paper focuses on the tracking control problem for switched nonlinear ship maneuvering time-delay systems with only a heading angle available by adaptive neural network (NN) output feedback. Using the backstepping method, an adaptive NN control mechanism is designed to solve the problem cooperated with the state observer. The uncertain terms of the system are approximated by NNs, and the state observer is designed to estimate the yaw rate and rudder angle. The unknown time delays are overcome by exploiting the common Lyapunov-Krasovskii functionals (CLKFs). Combined with error transformation, the proposed control method guarantees that i) all of the signals for the system are semi-global uniformly ultimately boundedness (SGUUB) under arbitrary switching; and, ii) the tracking error of system output keeps within a small neighborhood around the origin. The results of simulation results are shown to demonstrate the feasibility of the control strategy.

In recent years, the device concept called Integrated Microfluidic Circuits (IMCs) has been proposed in the microfluidic literature. The IMCs include fluids, rigid channels and flexible membranes, and their behavior is coordinated with the membrane deformation and fluid flow. The IMC allows the control function being realized by the fluid itself, like the concept of self-control. In this paper, we generalize the concept of IMC to the concept called soft microfluidic system (SMS). In SMS, there are no electronics, and materials are soft, meaning the mechanical property of materials is close to that of materials of biological body. A SMS can exhibit the robotic behaviors, namely movement, sensing, actuation, and control. In this paper, we further propose two concepts upon the SMS concept. The first concept is a switch valve which is continuous in that the switching occurs between two fluid configurations: Configuration 1 (flow rate x1 for flow 1 & flow rate x2 for flow 2), Configuration 2 (flow rate x2 for flow 1 & flow rate x1 for flow 2), where x1%+x2%=100%. The second concept is regarding the structure of a microfluidic system, that is, horizontal stacking of multiple layers rather than vertical stacking of multiple layers SMS. This paper explores these concepts and provide justification of the feasibility of implementing these concepts.

Solitons, arising from nonlinear wave-matter interactions, stand out for their intrinsic stability during wave propagation and exceptional spectral characteristics1. Their applications span diverse physical systems, including telecommunications2, atomic clocks3,4, and precise measurements5,6. In recent years, significant strides have been made in developing cavity-optomechanics based approaches to generate optical frequency combs (FCs). In this study, we present an innovative approach, never explored before, that leverages elastomer membrane (EM)-cavity optomechanics to achieve the generation of soliton FCs, a highly sought-after phenomenon in the realm of nonlinear wave-matter interactions. Our method represents a significant breakthrough due to its streamlined simplicity, relying on a single continuous-wave (CW) laser pump and an externally applied acoustic wave exciting an EM-cavity, which gives rise to phonons, quantized vibrational energy states intrinsic to the elastomer's crystalline lattice structure. The mechanical resonator and electromagnetic cavity resonance are parametrically coupled within the microwave frequency range, collectively orchestrate the process of soliton FCs formation with remarkable efficiency. Numerical simulations and experimental observations demonstrate the emergence of multiple stable localized optomechanical wave packets, characterized by a narrow pulses time-domain response. Crucially, by setting the acoustic wave frequency to match the natural frequency of the EM resonator, the solitons' teeth are precisely spaced, and the EM's motion is significantly amplified, giving rise to a Kerr medium. The successful realization of optomechanical stable solitons represents a monumental advancement with transformative potential across various fields, including quantum computing and spectroscopy.

In general, applications on a densely populated network are slower. When there are no opportunities to interact with the devices on the network, the user is forced to communicate at some cost. Thus, the inconsistency that exists there increases the cost over that dense network. The single way to evaluate prospect usage is to look at that have used in the earlier period. This paper proposes an upgraded approach to upgrading existing services within the Ultra Dense cloud Network (UDN). In this way the cost for the services available there is calculated in advance and a system is developed to manage it effectively. This proposed method clearly shows that the effective cost can be managed by combining high-costservices and low-costservices separately. This will help to manage the various communication processes to achieve high effectiveness in Ultra Dense cloud Network (UDN). The proposed method achieves 93.28% of Cost-effective Data Management.49% of Application log failure, 42 % of system log failure, 98% of network log management, 96% of security log management, 99% cost effective management.

The current field of automotive energy recovery primarily focuses on vehicle inertia, tire motion, and component vibrations. However, the potential for collecting vibrational energy from the fluid–structure interactions of air and liquid two-phase flows within tanker trucks equipped with anti-wave baffles remains largely unexplored. Typically, traditional anti-wave baffles in tanker trucks serve a single purpose: to reduce the inertial impact force of the internal liquid, thereby enhancing vehicular stability. This study proposes a regenerative buffering baffle device that combines anti-wave functionality with the innovative feature of energy harvesting. The proposed device utilizes an inverted Y-shaped baffle combined with a small portion of smart material to collect flow-induced vibrational energy to power low-power wireless sensors used for vehicle health monitoring. The fluid-electromechanical interaction between two-phase flow and smart baffle structures is investigated in detail. Optimized design parameters resulted in a harvested power output of 745.89 μW, while maintaining anti-wave performance equivalent to conventional anti-wave baffle designs. Additionally, a long-duration driving test demonstrated the continuous power supply capability of the proposed device for Internet of Vehicles (IoV) nodes, generating 774.99 mJ of energy over approximately one hour of operation. The proposed anti-wave baffle also boasts enhanced practicality due to its ease of disassembly and maintenance, setting it apart from traditional designs. © 2025 Elsevier Ltd

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade. © 2023 The Authors.

The dither axis bending occurs in the presence of input acceleration acting on the laser block of the ring laser gyro (RLG) due to the limited transverse stiffness of the dither motor, which will cause g-sensitive misalignments under vibration environments. A novel RLG SINS dynamic error compensation method is proposed under vibration environments in this paper. G-sensitive misalignment model of the RLG unit is developed. The equivalent gyro drift model under rotation and acceleration environments is deduced to describe the dynamic error. Optimized vibration experiments are conducted to estimate the unknown parameters. Vibration experiment results prove the validity of this method. © 2018, Pleiades Publishing, Ltd.

As a flexible grid-connection method, idle-load grid-connection is widely used in AC excitation variable speed constant frequency (VSCF) wind power generation systems with Doubly-Fed Induction Generator (DFIG). In this paper, the idle-load grid-connection control strategy of the VSCF doubly-fed wind turbine is designed. Under the condition of open circuit on the stator side, the rotor exciting current is adjusted to realize VSCF at the stator side while decoupling the output active power and reactive power. Finally, a semi-physical real-time simulation platform of doubly-fed wind power generation system based on dSPACE is established. As a result, there was no inrush current at the time of grid-connection, which verified the correctness of the control strategy, at the same time, accuracy and real-time of the control system were proved.
