Simulations are commonly used to develop and evaluate video encryption algorithms. Although these app.o.ches are useful for demonstrating theoretical feasibility and algorithm performance, they neglect practical challenges and real-world communication conditions. This oversight creates a critical gap in evaluating their effectiveness and security in practical applications. In this paper, we describe a novel, to the best of our knowledge, video encryption scheme that emp.o.s a modified chaotic Colpitts oscillator, a customized Josephus p.o.lem, and ribonucleic acid (RNA) operations, and is implemented in visible light communication (VLC) environment. The modified Colpitts oscillator reveals significant phenomena, the most p.o.inent for this study being chaos. The encryption scheme involves block scrambling and pixel-level permutation emp.o.ing a customized Josephus p.o.lem and a column and row shifting technique. Diffusion is then achieved through a custom Josephus p.o.lem-oriented RNA operation combined with basic RNA operations and cipher block chaining (CBC). Based on the results, we found that the customized Josephus p.o.lem-based permutation performed more efficiently than traditional methods, whereas the column and row shifting permutation was more robust. By eliminating key sequence coding and item-to-item operations, the p.o.osed RNA operation reduces computational overhead. This video encryption scheme is p.o.en to be effective and resilient at securing video data transmitted over the VLC channel, and it constitutes a significant advancement in areas such as surveillance, medical imaging, and military communication requiring robust secured video data. © 2025 optica publishing Group.

This paper presents a novel biological neural networks based on memristive Tabu learning neuron (MTLN) model influenced by electromagnetic radiation. Despite the model having an unstable equilibrium plane, numerical investigation without the influence of electromagnetic radiation reveal that when increasing the memristor strength induces complex phenomena, including the coexistence of infinite bubbles of bifurcations, offset plane coexistence of various attractors. Furthermore, electromagnetic radiation can significantly impact the system's behavior, giving rise to hyperchaotic dynamics. A decent understanding is seen between the mathematical outcomes, app.o.ed through trial execution on an Arduino microcontroller-based. The insights gained from neural dynamics could pave the way for applications in neuromorphic computing, engineering, and brain-machine interfaces. Based on the complex dynamics of the model, a data privacy of biomedical data has been build and reveals good results, and enable to resist to robust attacks. © 2024 The Author(s)

An app.o.ch to intelligent p.o.ess automation based on a society of BDI-agents is presented in this paper. According to this app.o.ch a higher-level multi-agent systems based automation layer supervises an ordinary p.o.ess automation system. The purpose of the agent layer is to monitor the operation of the lower-level automation system and semi-autonomously reconfigure its control logic when needed. The agent layer operates as a multi-agent system consisting of BDI-agents, which cooperatively create and run reconfiguration sequences on the ordinary automation system in order to adapt its control logic to various situations. The adaptation p.o.ess may take place both in reactive and deliberative fashion. In this way the app.o.ch aims to increase the flexibility and responsiveness p.o.erties of the automation system. The app.o.ch is demonstrated with a laboratory test p.o.ess where p.o.ess startup and fault recovery experiments have been performed. Results from the experiments are described. © 2005 IEEE.

The business op.o.tunities in after-sales services such as condition based maintenance were noticed by many vendors of p.o.ess and automation equipment before adequate standards and architectures became available. Consequently, at a client's premises there are many units of p.o.ess equipment, software modules and Internet connections that have been installed by different vendors, and this uncoordinated work has created serious interoperability, maintainability and security p.o.lems. This paper p.o.oses an open standards-based service architecture for industrial telematics that sup.o.ts interoperability, software component lifecycle management and secure execution and communication of components in a multi-vendor environment. © 2004 IEEE.

The application of quantitative feedback theory (QFT) to design robust controller for a DC-DC boost converter operating in continuous conduction mode (CCM) is investigated in this paper. The controller is designed to p.o.ide good attenuation of the load disturbances in spite of practical limitations on the achievable closed-loop performance (i.e. right-half-plane zero) and in the presence of other design constraints including closed-loop tracking and robust stability. A prefilter is subsequently designed in order to imp.o.e the transient and steady state control responses. Tracking control characteristics are analyzed through computer simulation for a peak-current-mode (pCM) controlled boost converter in order to demonstrate the effectiveness of the p.o.osed control methodology.

An app.o.ch to extend p.o.ess automation systems with cooperating subp.o.ess agents is presented in this paper. According to this app.o.ch a society of subp.o.ess agents supervises an ordinary p.o.ess automation system. The functionality of this agent layer includes supervising the lower-level automation system, semi-autonomous reconfiguration of its control logic when needed and query p.o.essing for external systems. In this way the app.o.ch aims for enhancing the operational flexibility of the automation system. The subp.o.ess agents utilize several agent-based cooperation mechanisms in order to be able to perform their tasks. The app.o.ch is demonstrated with a laboratory test p.o.ess where p.o.ess startup and fault-recovery scenarios have been imitated. Experiences from initial test runs are described, too. © Springer-Verlag Berlin Heidelberg 2003.

Utilizing 3D Height Measurement in particle Size Analysis

引用

IFAC p.o.eedings Volumes 2008年第2期41卷 3292-3297页

作者： J. Kaartinen A. Tolonen Helsinki University of Technology Department of Automation and Systems Technology Control Engineering Laboratory P.O. Box 5500 FIN-02015 TKK Finland

This paper introduces a novel app.o.ch for performing non-invasive particle size analysis for a material stream running on a standard conveyor belt. The measurements, carried out with a 3D laser scanner and a measuring belt weigher, are accurate, robust and real world physical measures. The 3D data obtained with the laser scanner enables more accurate analysis than the spatial monochrome or colour images that are commonly used in this field. In this paper the p.o.osed analysis method is used in mineral p.o.essing application to get information about particle size distribution of the ore flow from the mine to a screening station at the surface. This information can be used to optimize operation of a semi autogenous grinding station used in pyhäsalmi. However, with certain limitations, the analysis method can be utilized in different kinds of applications.
