Digital platforms that manage manufacturing applications are complex systems that must provide flexibility to support the execution and reconfiguration of manufacturing plans. The use of modeling approaches may help dealing with this complexity, but the information models should be based on industrial standards to enable their applicability to different manufacturing scenarios. This work contributes a modeling approach towards the definition of information models for achieving manufacturing flexibility in accordance with the reference architecture RAMI 4.0. To that end, this work analyses the reference models that made up RAMI 4.0 to align their requirements with those necessary to support manufacturing flexibility. As a proof of concept, this work illustrates the application of the proposed models in an agent-based platform. © 2020 IEEE.

The article is devoted to the use of mathematical models of the dynamics of heterogeneous populations, and computer simulation based on the above models allows to identify general trends in subpopulations, predict the state of the system and obtain results on possible consequences of artificial intervention. Also, the use of mathematical models can predict the spread of genetic anomalies. The authors propose a model of subpopulation dynamics with a logistic function as a basic one. It is concluded that the system-wide dynamics of subpopulation processes depends not only on the reproductive potential of subpopulations, but also on the intrasystemic dynamics that objectively occur in such systems. The adequacy of the proposed mathematical model is proved. © 2022 IEEE.

Pre-stabilised Predictive Functional control for Open-loop Unstable Dynamic systems

Predictive functional control (PFC) is the simplest model-based algorithm, equipped with the attributes of a fully fledged predictive controller but at the cost and complexity threshold of a standard PID regulator. It has proven benefits in controlling stable SISO dynamic systems, but similarly to its competitor PID, it loses efficacy when a challenging application is introduced. In this paper, we present a modified PFC approach, especially tailored for open-loop unstable processes, using pre-stabilisation to efficiently control the undesirable dynamics at hand. This is essentially a two-stage design scheme with implications for PFC tuning and constraint handling. The proposal, nevertheless, is straightforward and intuitive, and provides improved closed-loop control in the presence of external perturbations against the standard PFC, and significantly better performance overall compared to the common PID algorithm, as demonstrated in a numerical case-study.

The article deals with the aspects of voltage stabilization of an induction generator in a system with a capacitive current relay regulator. Simulation is carried out by the process in an induction generator with capacitor excitation with relay regulation of capacitive current. The parameters of the relay system are determined when creating an autonomous power source based on induction generators. The proposed voltage regulation method was tested on a 2.2 kW induction generator. The simulation results obtained using the mathematical model were compared with the characteristics obtained using the experimental setup. © 2021 IEEE.

Understanding how cell fate is determined when exposed to extreme stresses such as heat shock is critical in biomedical systems. It has long been understood that exposure of cells to high temperature typically protect themselves with a heat shock response (HSR), where accumulation of denatured or unfolded proteins triggers the synthesis of heat shock proteins (HSPs) through the heat shock transcription factor, e.g., heat shock factor 1 (HSF1). Recent experimental work has also shown that protein posttranslational modifications (PTMs) such as SUMOylation play crucial roles in cellular responses to heat shock. As a complementary approach to the current experimental methodologies, in this study we aim to develop a mathematical model of SUMOylation-development synergism of HSR for the purpose of studying the dynamical behaviour of HSR quantitatively. The structure of our dynamical model is derived mostly from mass action kinetics while the model parameters are optimized by using a genetic algorithm (GA) based data-driven approach. The preliminary results show GA based data-driven approach has potentials for our modelling purpose.

In this paper, we present a distributed version of the k-means algorithm for multi-agent systems with directed communication links. The goal of k-means is to partition the network’s agents in mutually exclusive sets (groups) such that agents in the same set have (and possibly share) similar information and are able to calculate a representative value for their group. Our distributed algorithm allows each node to transmit quantized values in an event-driven fashion, and exhibits distributed stopping capabilities. Transmitting quantized values leads to more efficient usage of the available bandwidth and reduces the communication bottleneck, whereas distributed stopping preserves available resources. We characterize the properties of the proposed distributed algorithm and show that its execution (on any static and strongly connected digraph) will partition all agents in mutually exclusive clusters in finite time. We conclude with examples that illustrate the operation, performance, and potential advantages of the proposed algorithm.

A supervisory monitoring scheme is designed for the control of infectious diseases. The design is based on the tested accumulated information entropy of the absolute error of the model versus the observed data. Such a supervisory loss function is minimized at each supervision time-interval occurring in-between each two consecutive switching time instants. The design method allows to set through time the active model, within a prescribed parallel structure of potential models, each with its own coefficient transmission rate. Such an active model generates the vaccination and or treatment controls to be injected to the monitored population. © 2020 IEEE.

In the present day, the Internet of Things is becoming more and more popular. Enabling continuous connectivity and packet routing in this kind of network is difficult because of the resource limitations that are a feature of IoT. Reduce end-to-end latency, conserve energy, and balance network load are the three basic objectives of lightweight routing protocol. In this paper, we give a quick review of the IPv6 Routing Protocol for Low-Power and Lossy Networks-based routing protocols of VANET already in use and discuss their advantages and disadvantages. More specifically, we examine a few chosen VANET routing protocols and contrast their performance based on metrics like packet delivery ratio, Throughput, End to end delay, Routing- Cost, etc.

Operational loads have both static and dynamic characteristics. Dynamic loads occur during the operation of the considered mechanism, both during acceleration and deceleration periods, as well as during steady motion due to the movement of the moving element along an uneven path caused by the presence of the working environment on the elements over which the filter-press plates are moving. The dynamic loading is significant and affects the formation of plate-side displacements during their movement while performing the technological operation. Experimental studies of the load on the movement elements were conducted to determine optimal control modes for the filter-press plate movement mechanism, aiming to avoid overloading during stopping and filter jamming. To analyze the loading, discretization of random processes of the filter movement mechanism loading was performed. The sequence of calculating the statistical characteristics of the schematized dynamic process is presented. Based on experimental data, mathematical calculation of the results of schematization and the type of probability distribution law was carried out. To select the law that best reflects the experimental data distribution of load amplitudes, the Kolmogorov-Smirnov goodness-of-fit criterion was applied. According to the calculation results, it was found that the Weibull distribution law adequately reflects the distribution of amplitudes since its corresponding Kolmogorov-Smirnov criterion value is the smallest.
