Residual-Regime Markov Modelling for Predictive Control in Cyber-Physical Systems

/in /by

Cyber-physical systems operate through a continuous interaction between physical processes, computational intelligence, communication networks and control mechanisms. Their behaviour is rarely fully deterministic: sensor noise, delayed communication, nonlinear dynamics, regime changes and early-stage failures create uncertainty that cannot be adequately represented by a single forecasting or control method. This paper proposes an original Residual-Regime Markov […]

Mathematical Reliability Modeling of Cyber-Physical Systems: From Classical Failure Theory to Multilayer Predictive Indices

/in /by

Cyber-physical systems (CPS) require a reliability theory that is broader than the classical probability of failure-free operation of a technical component. In CPSs, failure can be caused by deterioration, sensor error, delay in communication, software malfunction, control problems, cyber vulnerabilities, human interaction, and stress due to environment. This paper offers a mathematical approach to CPS […]

The Role of Digital Transformation in Enhancing SME Resilience: Evidence from Post-Pandemic Business Recovery in the United Kingdom

/in /by

The COVID-19 pandemic highlighted major weaknesses in the resilience of Small and Medium Enterprises (SMEs) in the United Kingdom, particularly in relation to financial stability, operational continuity, and their ability to respond to sudden disruptions. As SMEs make up the vast majority of the UK firms and a significant share of private-sector employment, the crisis […]

Functional and Radiological Outcomes of Closed Ankle Fractures Managed Non-Operatively Among Adults at Mulago National Referral Hospital Six Months Post-Injury: A Cross-Sectional Study

/in /by

Background: Non-operative management is a common approach for treating closed ankle fractures at Mulago National Referral Hospital (MNRH) due to its potential benefits, including shorter hospital stays and the absence of surgical risks. Evaluating functional and radiological outcomes is essential for determining the success of this treatment. This study aimed to evaluate the functional and […]

Tamarind Juice Assisted Benign Synthesis Of 2,3-Dihydro-1h-Perimidine Derivatives

/in /by

A green and efficient way to make 2,3-dihydro-1H-perimidine derivatives is through a one pot reaction of 1,8-diaminonaphthalene with different aromatic aldehydes using tamarind (Tamarindus indica L.) juice. The reactions were carried out in mild conditions, giving us the desired products in good or excellent yields with short reaction times. Tamarind juice was inexpensive, and easily […]

The Effects of Mind Mapping on English Paragraph Writing among Vietnamese High School Students

/in /by

Writing English paragraphs remains a challenge for many EFL high school students, particularly in organizing ideas, developing relevant content, and producing coherent written texts. Mind mapping has been suggested as a useful pre-writing technique because it helps learners generate ideas visually and arrange them before drafting. This study investigated the effectiveness of mind mapping on […]

Association of Sociocultural Factors and Health Literacy Levels with Cervi-cal Cancer Early Detection Among Women in Reproductive-Age Couples in the Service Area of the Laosu Community Health Center in 2025

/in /by

Background: Cervical cancer remains a major cause of death among women, particularly in settings where early detection coverage is low. Objective: This study analyzed the association of sociocultural factors and health literacy with cervical cancer early detection among women in reproductive-age couples in the Laosu Community Health Center service area in 2025. Methods: This quantitative […]

From Poetry to Opera: Pushkin And Tchaikovsky’s Eugene Onegin in A Holistic Accordance

/in /by

The present article examines Tchaikovsky’s Eugene Onegin to demonstrate how a holistic approach can deepen the performance of opera; the approach integrates the composer’s dramaturgical strategies, the literary source, and critical scholarship into a unified interpretive framework. The discussion focuses on Onegin’s rejection aria and establishes that Belinsky’s characterisation of Onegin as an “involuntary egoist” […]

Motor Vehicle Growth in Guyana (2000–2025): Statistical Trends, Forecasting, And Infrastructure Implications

/in /by

Motor vehicle registrations are a key indicator of transport demand, economic development, and infrastructure pressure. This study examines long-term trends in motor vehicle registrations in Guyana from 2000 to 2025 and generates forecasts for 2026–2030 using time-series modelling, including an ARIMA (0,1,0) model with drift. The results show a strong and sustained increase in total […]
