“…The periodic voltage v(t), which is depicted in Figure 1a, can be found analytically using frequency characteristic (57). Its formal representation, which is written with 2-digit precision for the sake of compactness, is as follows: The effective values of the voltage Veff and current Ieff, evaluated using ( 40) and ( 41), are, respectively, 153.0825 mV and 3.5355 mA, whose product yields the apparent power by definition (39): Papp = 541.2 μVA.…”

“…In the case of unknown period, as often happens in practice, one can take on an appropriate period estimator prior to tuning the model parameters. Such a period estimator can be implemented via either synchronous averaging [39] with CS detection [40,41] or more promising techniques based on sample coherency analysis [42,43].…”

This paper proposes a cyclostationary based approach to power analysis carried out for electric circuits under arbitrary periodic excitation. Instantaneous power is considered to be a particular case of the two-dimensional cross correlation function (CCF) of the voltage across, and current through, an element in the electric circuit. The cyclostationary notation is used for deriving the frequency domain counterpart of CCF—voltage–current cross spectrum correlation function (CSCF). Not only does the latter exhibit the complete representation of voltage–current interaction in the element, but it can be systematically exploited for evaluating all commonly used power measures, including instantaneous power, in the form of Fourier series expansion. Simulation examples, which are given for the parallel resonant circuit excited by the periodic currents expressed as a finite sum of sinusoids and periodic train of pulses with distorted edges, numerically illustrate the components of voltage–current CSCF and the characteristics derived from it. In addition, the generalization of Tellegen’s theorem, suggested in the paper, leads to the immediate formulation of the power conservation law for each CSCF component separately.

“…To ensure the higher performance of computational processes, the concept of agents was adopted and, later, agents supporting the DM process were introduced in a system known as agent mining (AM). The distributed nature of AM provides several advantages for DM, such as autonomy, scalability, reliability, security, interactivity, and high speed (Han, Kamber, and Pei 2012;Borodin et al 2019;Guschina et al 2019). The ability of agents to learn from their experience complements the data mining process.…”

This article considers the main models of the architecture of agency systems of project-oriented management as stages of their development. The agent technology allows us to decentralize problem solving and create complex systems of project-oriented management, combining various processing methods such as modeling, reasoning, and machine learning, and also allows us to distribute knowledge. One of these models is an aggregated architecture for systems of project-oriented management, based on agents of a marked deductive system. This approach allows us to divide algorithms into separate modules and distribute the knowledge base into parts. The focus is on existing multi-agent data mining architectures and the roles of agents in them. An architecture is described of Existing Methods and Technologies of Project-Oriented Management for Government Agencies ... to support the decision-making process in conjunction with the use of event-driven and task-driven data mining agents, as well as helpers and knowledge management agents. The article then considers a mathematical model of the proposed decision-making system, identifies key parameters, and suggests improvements to the model based on the proposed integrated software solution. The practical significance of this study is determined by the fact that not only was the software architecture developed and presented for the first time, but also a fully extended mathematical model of a project-oriented management system.
