Indoor exposure to radon (222Rn) and thoron (220Rn) in healthcare environments represents a potential radiological risk for both patients and staff. This study is the first systematic assessment of radon and thoron activity concentrations at the University Clinical Center of Kosovo (QKUK), the largest healthcare facility in the country. Measurements were performed during a 94-day monitoring campaign from early spring to early summer using passive CR-39 diffusion chamber detectors and active real-time monitors (RadonEye RD200). In addition, twin-chamber detectors were paced at selected locations to simultaneously evaluate radon and thoron contributions. Radon concentrations ranged from 24 to 360 Bq m−3 with an arithmetic mean of 72 Bq m−3, corresponding to estimated annual effective doses between 0.41 and 6.12 mSv y−1. Thoron concentrations varied from 5 to 45 Bq m−3, contributing up to 20
Pneumonia remains a major global health concern, particularly in low- and middle-income countries, where it contributes substantially to morbidity and mortality. In this study, a fractional-order mathematical model was developed to investigate the transmission dynamics of pneumonia, incorporating key control measures such as vaccination, treatment of infected individuals, reinfection dynamics, and environmental interventions. The model employed three types of non-integer order differential operators—Caputo, Caputo–Fabrizio, and Atangana–Baleanu. The existence and uniqueness of solutions were established using fixed-point theory. Model calibration was performed using monthly pneumonia hospitalization data for children aged 0–14 years in England from January 2021 to March 2024, representing a post-COVID phase characterized by increased respiratory illness activity. Parameters were estimated through least-squares optimization under biologically realistic constraints, and the simulated results showed strong agreement with observed hospitalization trends, confirming the model’s validity. Numerical simulations demonstrated that higher fractional orders reduce transmission speed, lower the peak number of cases, and extend outbreak duration, reflecting the memory-dependent nature of fractional systems. Sensitivity analysis further revealed that effective environmental interventions and prompt treatment of infected individuals play a crucial role in reducing disease transmission. The study provided a robust and flexible approach to understanding pneumonia dynamics and highlights the importance of integrating vaccination, timely treatment, and environmental improvements as complementary strategies to sustainably reduce the pneumonia burden.
The purpose of this research is to develop a set of Hermite–Hadamard–Mercer-type inequalities that involve different types of fractional integral operators such as classical Riemann–Liouville fractional integral operators. Furthermore, some fractional integral inequalities are obtained for three-times differentiable convex functions with respect to the right-hand side of the Hermite–Hadamard–Mercer-type inequality. Moreover, several new results regarding Young’s inequality, bounded function and L-Lipschitzian function are deduced. The paper presents additional remarks and comments on the results to make sense of them. To illustrate the key findings, graphical representations are provided, and applications involving special means, midpoint formula, q-digamma function and modified Bessel function are presented to demonstrate the practical utility of the derived inequalities.
This project focuses on the design and implementation of a mechatronic system intended for intelligent production lines. The candidate will analyze and describe the structure and functionality of mechatronic systems commonly used in modern production and assembly industries. Special emphasis will be placed on deconstructing the design process and understanding the integration of mechanical, electrical, and electronic components that form a complete mechatronic system. A key objective of the project is the identification and detailed explanation of the electrical and electronic elements involved in automated production lines. Furthermore, these components will be used to develop a fully functional automated control system based on feedback principles. The control algorithms will be implemented using Programmable Logic Controllers (PLCs), specifically those integrated within the FESTO Modular Production System (MPS). Beyond the basic functionalities of the MPS system, the project will introduce several advanced features to enhance productivity and efficiency. These include counting completed products, optimizing sorting programs for improved energy efficiency, and identifying missing components to ensure successful product assembly. Through this work, the project aims to contribute to the development of intelligent, adaptive, and efficient mechatronic systems in automated manufacturing environments.
Accurate modeling and simulation of accelerometers are critical for the development and validation of avionics systems, where precise inertial measurements are essential for navigation, guidance, and control. This study presents a comprehensive approach to the schematization and simulation of an aeronautical accelerometer using MATLAB/Simulink. A detailed physical and mathematical model of a capacitive MEMS-based accelerometer is developed, capturing both mechanical dynamics and electrical signal processing. Multiple simulation architectures are constructed to evaluate different levels of model complexity and fidelity. Comparative analyses are performed between simplified linear models and high-fidelity nonlinear representations to assess trade-offs in computational efficiency and accuracy. Simulation results are validated against benchmark performance data, focusing on key performance metrics such as sensitivity, bandwidth, noise characteristics, and transient response. The findings highlight the importance of model fidelity in high-precision applications and provide guidelines for selecting the appropriate modeling approach based on system requirements. This work contributes to the testing processes of flight control systems by offering a validated simulation framework that supports detailed performance analysis of aeronautical accelerometers.
