Special Issue Information

Dear Colleagues,

In today's data-rich environment, artificial intelligence (AI) tools are playing an increasingly pivotal role in many areas of science and engineering. This has led to a surge in data science, which is becoming a powerful force in decision making. It is therefore vital to provide users with reliable, optimal and robust information about the state of the variables that govern the dynamics of processes, nature and the environment. In this context, sensors are of critical importance, as they are responsible for monitoring the value of physical quantities and detecting changes. It is therefore essential to have reliable and robust sensor systems that can accurately and consistently measure these quantities. Furthermore, to gain a deeper understanding of the subject, it is essential to consider the role of the sensor, the signal conditioning circuits, the electronic instrumentation and the correct transmission of information in human–nature interactions. 

However, it is important to note that process data are often unavailable or affected by a significant amount of noise and random disturbances in both research and industry settings. It should be noted that these processes may also be multivariable, non-linear and time-varying. As a result, AI tools are not effective solutions for addressing the issues that impact these processes. The most effective method for controlling these processes is through a scientific approach that incorporates system identification, mathematical-physical modeling, robust and optimal control and the appropriate use of electronic instrumentation, sensors and actuators. 

The primary objective of this Special Session is to publish works focused on the design and construction of sensor systems with applications in various scientific and engineering fields, including electrical, mechanical, civil, chemical and interdisciplinary engineering, as well as subdisciplines within these fields. Finally, papers that address innovative solutions in sensor design as well as signal conditioning and signal processing techniques for sensors are welcome.

Given the significant impact of air pollution on global health, the continuous and precise monitoring of air quality in all populated environments is crucial. Unfortunately, even in the most developed economies, current air quality monitoring networks are largely inadequate. The high cost of monitoring stations has been identified as a key barrier to widespread coverage, making cost-effective air quality monitoring devices a potential game changer. However, the accuracy of the measurements obtained from low-cost sensors is affected by many factors, including gas cross-sensitivity, environmental conditions, and production inconsistencies. Fortunately, machine learning models can capture complex interdependent relationships in sensor responses and thus can enhance their readings and sensor accuracy. After gathering measurements from cost-effective air pollution monitoring devices placed alongside a reference station, the data were used to train such models. Assessments of their performance showed that models tailored to individual sensor units greatly improved measurement accuracy, boosting their correlation with reference-grade instruments by up to 10%. Nonetheless, this research also revealed that inconsistencies in the performance of similar sensor units can prevent the creation of a unified correction model for a given sensor type. Full article

The aim of this paper is to present an approach to condition monitoring of an actuated mechanical system operating in a steady-state regime. The state signals generated by the sensors placed on the mechanical system (a lathe headstock gearbox) operating in a steady-state regime contain a sum of periodic components, sometimes mixed with a small amount of noise. It is assumed that the state of a rotating part placed inside a mechanical system can be characterized by the shape of a periodic component within the state signal. This paper proposes a method to find the time domain description for the significant periodic components within these state signals, as patterns, based on the arithmetic averaging of signal samples selected at constant time regular intervals. This averaging has the same effect as a numerical filter with multiple narrow pass bands. The availability of this method for condition monitoring has been fully demonstrated experimentally. It has been applied to three different state signals: the active electrical power absorbed by an asynchronous AC electric motor driving a lathe headstock gearbox, the vibration of this gearbox, and the instantaneous angular speed of the output spindle. The paper presents some relevant patterns describing the behavior of different rotating parts within this gearbox, extracted from these state signals. Full article

Runway surface friction is critically important to safe aircraft operations and mostly depends on the surface texture, which provides grip in the presence of contamination and directly affects the friction coefficient in general. Microtexture assessment is the most challenging part of texture assessment since there is no standardised pavement microtexture control method in runway maintenance and management practice. The purpose of this study was to develop a simple laser profilometer and analysis model and subsequent validation for use in runway friction surveys. To that end, a simple laser profilometer was developed, and a profile picture analysis and macrotexture filtration method were designed. Test results were compared to the stylus-based roughness tester and the British Pendulum Tester. The proposed profile picture analysis and profile smothering and filtration methodology, based on linear approximation, is simpler and more effective for the case of macrotexture filtration for the friction survey. The laser profilometer model results were highly correlated with the stylus-based roughness tester results (R2 = 0.99). The average roughness of the microtexture profile, after smothering and macrotexture filtration, also showed good correlation with the British Pendulum results (R2 = 0.78). The results from this study confirm the possibility of texture assessment for routine runway friction surveys using a simple and economical laser profilometer, which is not routinely available in current airport surface friction management.
