the stability problem of fractional discrete-time linear systems with delays has been analysed. the state-space model with a time shift in the difference has been considered. New necessary and sufficient conditions for the asymptotic stability and the practical stability have been established. the systems with only one matrix have been also analysed. It has been shown that such systems are asymptotically (practically) stable if all eigenvalues of the state matrix lie in the stability region of the complex plane.

the article explains an interoperable method for the exchange construction information, particularly concerning civil infrastructure projects. Open BIM standards offer a neutral platform for information exchange, enhancing data integration throughout all construction and operation phases. the Information Delivery Specification Standard (IDS), a component of open BIM standards, along withthe Information Delivery Manual (IDM), facilitates the timely and organized exchange of information. the research was aimed to determine if generating requirements for open BIM models could be automated in accordance with IDS standards. It was also assumed that the input data are the requirements from the BIM Execution Plan (BEP). the research results show the ability to generate IDS files automatically, which improves model verification and enables quick adjustments. Despite the challenges, the use of IDS as an element of open BIM standards enhances the construction processes.

the presented paper contains comparison two algorithms for searching optimal value of PID controllers: particle swarm optimization (PSO) and fractional-order particle swarm optimization (F-PSO) for the control system of capsubot robot. A cost function which is used with PSO and F-PSO is presented. At the end, the obtained simulation results are shown and discussed.

the consensus problem for a multi-agent system with linear agents is considered. the agents may exhibit a time delay, this delay is not required to be equal for each agent. It is shown that different values of the delay may prevent the follower agents to settle in the precise convex hull of the leader agents, however, they converge to a larger set that can be determined using the robust control methods. the results are illustrated by examples.

this paper is concerned withthe application of a velocity transformation-based control scheme developed for underpowered marine vehicles to other vehicles with a similar mathematical model to the underwater vehicle. the problem of applicability of known control algorithms to systems that differ from the original is important in that its solution makes it possible to adapt a known control strategy for a similar class of vehicles. It is then not necessary to construct a new algorithm, but it is enough to transform one that is known. the effectiveness of the proposed approach was verified using simulations for a 3 DOF hovercraft model and an 3 DOF indoor airship.

this research paper compares two neural-network-based adaptive controllers, namely the Hybrid Deep Learning Neural Network Controller (HDLNNC) and the Adaptive Model Predictive Control with Nonlinear Prediction and Linearization along the Predicted Trajectory (AMPC-NPLPT), for controlling a nonlinear object with delay. Specifically, the study investigates the effect of delay on the accuracy of the two controllers. the experimental results demonstrate that the AMPC-NPLPT approach outperforms HDLNNC regarding control accuracy for the given nonlinear object control problem.

Airborne transmission is a key element in the spread of viral contagion. To prevent this, health organization publish guidelines for every major disease outbreak. However, they are often based on researches carried out without access to modern solutions. In this paper, we propose usage of Bayesian inference as an additional, to computationally-intensive methods such as CFD or FEM, way to analyse short - range virus exposure. We build a spatial model, using INLA package, which allows us to optimize the complicated computational process and deal with conundrums of virus exposure modeling.

this paper presents the possibilities of controlling a robotic arm using voice commands withthe use of an external API responsible for speech-to-text translation. the article describes the creative process of designing the robot model and user interface included in the simulator used to control the robot. the software was developed in the Unreal Engine 4.27.2 environment using the built-in visual programming language - blueprint, as well as C++ and Python. the three-dimensional model was created entirely in Blender 3D software. the simulator's task is to faithfully reproduce manipulation of simple objects in real-time, as well as record and load the manipulator's trajectory along with all objects on the scene.
