Stylometric analysis of texts relies on learning characteristic traits of writing styles for authors. Once these patterns are discovered, they can be compared to the ones present in other text samples, to recognise their authorship. This recognition can be compromised if input datasets are prepared without taking into consideration possible stratification of the input space, leading to specific grouping of datapoints, or sub-classes within distinguished classes. The paper shows research dedicated to construction of various structures of input datasets, and combinations of such structures between train and test sets. In the research the influence of different stratification forms on the performance of selected popular classification systems was observed. To minimise the number of influencing factors, a task of authorship attribution was performed as binary classification with balanced classes. Stylometric descriptors exploited belonged to lexical and syntactic group, giving frequencies of occurrence for chosen style-markers. It resulted in real-valued attributes and these values were explored without applying discretisation, in order to avoid the possible bias of this procedure on observations. © 2022 The Authors.

This article presents a versatile model of failure prediction in control systems of objects with large time constants. The basic model of a control unit consists of deterministic finite automaton (DFA) which states correspond to states of the system where system variables satisfy a given set of constraints. System failures can be predicted on the basis of time series of the selected signals. Further diagnosis is performed on the basis of rough set theory and original algorithms for attributes' reduction and decision rule generation. A versatile failure prediction algorithm is constructed that integrates all involved techniques. Cooling systems are application examples of the proposed methodology. © 2023 IEEE.

The paper aims to optimize the energy consumption of industrial robots, with the goal of reducing operational costs and improving the sustainability of the production process. The methods discussed include using energy-efficient components, reducing idle times, and optimizing robot trajectory programming to minimize unnecessary movements. The project presents a simulation of an industrial process for sorting and depalletizing parts using a KUKA KR 4 Agilus robot, along with Arduino development boards for control and coordination. A color sensor system is employed for object detection, optimizing the robot’s movements based on the data collected. To analyze energy and time efficiency, two movement routines were compared: one based on SLIN and the other on SPTP.

This work introduces a method for closed-loop system identification using frequency analysis, employing Empirical Transfer Function Estimation (ETFE). By integrating optimization within a Monte Carlo framework, it enhances the precision of ETFE, resulting in minimized frequency response errors compared to actual system data. Leveraging controller information in an offline model fitting scheme, it achieves optimal realization of process dynamics. The method is evaluated on a data center rack-level cooling system, showing Bode magnitude plots of actual and estimated closed-loop and open-loop dynamics, with confidence intervals demonstrating algorithm consistency. Numerical evaluations confirm the feasibility and potential of the approach to improve offline closed-loop system identification performance in the frequency domain, beneficial for analysis and design. There will not be a comparative study for the introduced approach.

This article presents a study on the use of photovoltaic panels for storing electrical energy intended to power an HVAC unit placed in a residential room. To highlight this aspect, two specific scenarios will be considered. Thus, we aim to analyze whether the generated and stored energy is sufficient to fulfil the thermal comfort requirements of the user, while also considering the primary objective of minimizing energy consumption. To achieve this goal, the HVAC unit will be controlled by implementing a fuzzy system that determines its optimal activation based on the comfort level obtained from the user. The fuzzy system presents as inputs both environmental parameters and specific personal perception parameters of the user. The research results provide an insight into the efficiency of implementing photovoltaic energy storage systems for residential applications and propose solutions for optimizing energy consumption in the context of ensuring adequate thermal comfort. Thus, the study contributes to the development of sustainable and personalized energy solutions for smart homes.

Cyber-physical systems under hybrid cyber-attacks: Resilient event-triggered H∞ control approach

ISA Transactions 2025年

作者： VakilKandi, Sepideh Jahani Bayat, Farhad Jalilvand, Abolfazl Bartoszewicz, Andrzej Department of Electrical Engineering Faculty of Engineering University of Zanjan Zanjan Iran Institute of Automatic Control Lodz University of Technology Lodz Poland

This article introduces a novel adaptive event-triggered finite-time H∞ control approach for Cyber-Physical Systems (CPSs) under the influence of bounded disturbances, actuator faults, and randomly occurring hybrid cyber-attacks, including aperiodic DoS attacks, deception attacks, and replay attacks. This paper presents a novel integrated framework for hybrid attacks that consists of aperiodic DoS attacks, deception attacks, and replay attacks. To minimize continuous data transmissions in the network and maximize the utilization of limited resources, an adaptive periodic event-triggered mechanism (APETM) is developed by employing the DoS-dependent adaptive varying threshold. Compared to common event-triggered mechanisms, this method allows for periodic monitoring and effectively increases the lower bound of event intervals, making it well-suited for real-world applications. Initially, a new theoretical framework for cyber-physical systems is proposed, incorporating an adaptive periodic event-triggered mechanism under hybrid cyber-attacks, external disturbances, and actuator faults. Based on the established model, the Lyapunov-Krasovskii stability theory is employed to establish sufficient conditions for ensuring the finite-time stability with an H∞ performance level. Additionally, a linear matrix inequality technique is utilized to determine the controller gains and triggering parameters. The effectiveness of the proposed method is demonstrated through a simulation of the one-link flexible joint robot systems. © 2025 ISA
