This paper proposes a collaborative positioning framework that integrates an inertial measurement unit (IMU). An improved particle swarm optimization and adaptive unscented Kalman filter (IPSO-IAUKF) algorithm based on environmental assessment is also designed. The threefold contributions include: (1) A tightly coupled positioning system architecture is constructed by deeply integrating UWB ranging with IMU motion measurements; (2) An improved particle swarm optimization (IPSO) algorithm is proposed to optimize the initial coordinate estimation of UWB using a dynamic inertia weight strategy; (3) An adaptive Unscented Kalman Filter (UKF) framework is designed, incorporating an environmental state discrimination threshold and a real-time noise matrix update mechanism to dynamically optimize the covariance matrix, thereby enhancing positioning robustness in complex noise environments. Multi-scenario trajectory simulations and practical experiments are conducted based on the established positioning model. Numerical simulation results demonstrate that the proposed fusion framework achieves a 52.6 % improvement in positioning accuracy compared to standalone UWB solutions, with a 44.6 % enhancement in noise resistance under NLOS interference compared to traditional fusion algorithms. Further practical tests reveal that the IPSO-IAUKF algorithm achieves average positioning accuracy improvements of 52.1 %, 45.5 %, and 46.0 % in two typical noise environments compared to conventional UKF and algorithms 1 and 2 used in this paper, respectively, while the maximum positioning error decreases by 44.6 %, 23.9 %, and 29.7 %, respectively.

These events can lead to cellular and chemical changes in the brain, disrupting neural pathways and causing symptoms such as headaches, dizziness, cognitive difficulties, and emotional changes. Raising awareness about mTBI and implementing preventive measures to reduce its incidence and mitigate its impact on affected individuals is crucial. Head kinematics measurement is one of the quickest methods for making on-field initial diagnosis decisions. This paper describes the development of an open-source, low-cost, real-time device that can be attached to a helmet. It monitors the head kinematics data (linear acceleration and rotational speed). It sends it over a Wi-Fi connection to a web browser of a monitor device (PC or Mobile phone) connected to the same network so the user who observes the data can call a doctor to check mTBI symptoms. The device utilizes an inertial measurement unit (IMU) and high-g (g = 9.8 m/s<sup>2</sup>) linear accelerometers interfaced with an Internet of Things (IoT) based microcontroller (WeMos D1 mini) programmed using the Arduino IDE. This setup facilitates data visualisation through an interactive HTML webpage, enabling the user (e.g., coach, medical personnel) to assess the data and potentially recommend seeking medical attention if concerning readings are observed.

To mitigate these effects and support timely pavement repairs, continuous road condition monitoring is essential. Vibration-based measurement systems have gained prominence in recent years, but their accuracy can be significantly compromised by vehicle maneuvers, particularly on urban or curvy roads. Despite this, the influence of aggressive maneuvers has largely been overlooked in previous studies. In this paper, we address this gap by presenting a comprehensive investigation into the impact of abrupt maneuvers on vibration-based road quality measurement. We introduce a novel, computationally efficient soft-sensor algorithm that detects and isolates aggressive maneuvers using sensor data from existing road quality measurement systems, classifying them into four categories. This algorithm combines rule-based methods with machine learning, offering enhanced accuracy and lower computational costs compared to alternative approaches. In this way, the overall maneuver classification achieves an accuracy of 93%. By applying the introduced approach to identify and correct the influence of maneuvers, we achieved a 7% increase in accuracy of pavement quality classification in a suburban environment and a 10% increase in an urban environment. The proposed solution can be easily integrated into current vibration-based road quality measurement frameworks, enhancing their performance while maintaining scalability and low operational cost.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101816"},"PeriodicalIF":0.0,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the energy of the gamma emitting source, the design, and arrangement of the source geometry (including the point or rod sources), and the detector material (NaI (Tl) crystal or plastic scintillator) are crucial parameters. In this research, a nuclear level gauge, including the source, detector, and reactor containing urea and gases at high temperatures and pressures, was simulated by MCNPX Monte Carlo code and the results were compared and validated with experimental values. Then, the detector's response was evaluated and optimized based on the different arrangements of the radioactive source and its distances, as well as the type and geometry of the detector, and the best arrangement was selected. The comparison of the simulation results and the resulting analysis indicated that using point sources at specific distances (three points) instead of rod sources is a viable alternative due to its simpler structure, higher accuracy and stability, and lower production cost compared to the high cost of rod sources.
