The event-triggered cooperative output regulation problem of linear multi-agent systems has been addressed under the assumption that the system matrix of the exosystem is known to all agents in previous studies. To remove the assumption, this paper proposes an event-triggered adaptive distributed observer, which is designed to estimate the system matrix of the exosystem. With the proposed triggering...
A low-loss, compact TM-pass polarizer is demonstrated based on hybrid plasmonic grating on silicon-on-insulator platform. Since the large mode distribution mismatch and plasmonic effect significantly influence the transmission and reflection spectrum of the device, the traditional theory of Bragg grating cannot fully explain this phenomenon. Here, we proposed an analysis method which takes effective...
Online social networks (OSNs) have attracted millions of users worldwide over the last decade. In response to a series of urgent issues faced by existing OSNs, such as information overload, single-point failure, and the privacy issue, this paper introduces a self-organized decentralized OSN (SDOSN) over a social overlay resembling real-life social graph. The social overlay considers social relationship...
A CMOS-compatible athermal flat-topped silicon Mach-Zehnder filter is proposed and experimentally demonstrated using hybrid strip-slot waveguides. The measured temperature-dependent wavelength shift is −5 pm/K and the minimum insertion loss is 0.4 dB with a device dimensions of 170 pm × 580 pm.
This paper studies the output consensus problem of heterogeneous multi-agent systems with linear dynamics. The procedure of designing a novel distributed event-triggered control scheme is proposed. By utilizing the internal model principle, event-triggered strategy and some inequality techniques, it can be shown that the output consensus of the heterogeneous linear multi-agent systems can be achieved...
Network communication protocol reverse-engineering is important for malicious software analysis. Security analysts need to rewrite messages sent and received by malicious software according to the protocol to control the malware's malicious behaviors. To enable such rewriting, we need detailed information about the sent message by the malware program in target host in the network dialog. However,...
NH2+ ion implantation was performed at the energy of 80 keV with fluence of 2 × 10 16 ions cm −2 for silicon, and the implantation of amino groups on the silicon surface was verified by X-ray photoelectron spectroscopy (XPS) analysis. Well-defined gold nanoparticles (AuNPs) film was formed with a submonolayer coverage on the obtained NH2+ ion implanted silicon (NH 2 /Si) surface,...
This investigation proposes to deposit a ternary material W-Mo-Si as the conductive films for surface-conduction electron emitters. The components of this ternary film can be controlled by changing the sputtering targets and adjusting the sputtering power of the different targets. This study mainly analyses the electron emission of the co-sputtering using a W-Mo-Si target and Mo target. The micro-analysis...
Along with the development of technology and the advance of social productivity, the technology of TV and computer have been mostly method of modern information social spread and dealing with information. Video image superposition is one of the multimedia technology application fields; it is the associative production of the TV technology and computer technology. The technology of drawing beeline...
