Driver inattention is the primary cause of highway accidents. Various distractions can impair driving performance, posing a significant threat to road safety. This study uses a VR driving simulator to examine distracted driving, creating a simulated driving environment. It involves designing main and sub-driving tasks to replicate the cognitive load and distractions experienced by drivers. Data are collected using NASA-TLX scales, eye-tracking technology, and physiological signal acquisition. The impact of different distraction workloads on driver performance was assessed using statistical analysis and support vector machines (SVM). A multi-source data fusion model was developed to discriminate distracted driving behaviors. This research aims to provide theoretical insights and practical guidance for improving safe driving practices. © 2025 SPIE.

To address the issues of high risk, high cost, limited coverage, and low effectiveness in pressure vessel emergency drills, this study aims to construct a pressure vessel accident emergency drill system based on virtual reality technology. The system utilizes Unity3D to develop a human-computer interaction interface and implements various functional modules using C# scripting. The system incorporates features such as scenario simulation, safety education and training, interactive operations, multi-player collaboration, and feedback and evaluation, enabling drill participants to train and examine their emergency response skills within a virtual environment. To ensure the objectivity and comprehensiveness of the scoring system, this study employs a combined weighting method of the Entropy Weight Method and Analytic Hierarchy Process to analyze the weights of the operational steps in the exercise process. A comprehensive and objective scoring mechanism for the pressure vessel accident emergency exercise system has been designed, which evaluates the performance of the exercise personnel from multiple dimensions and levels. Furthermore, a comprehensive and objective rating mechanism for the emergency drill system of pressure vessels was designed to evaluate the performance of the drill personnel from multiple dimensions and hierarchical levels. This system effectively enhances participants' abilities in rapid response, emergency handling, and teamwork during accidents. © 2025 SPIE.

The Mie series has very important applications in electromagnetics(including optics).We employ a formulation for the Mie series which relies more on the derivatives of Legendre polynomials than Bessel *** formulas for derivatives related to Legendre polynomials are derived to realize the Mie series conveniently and to avoid treating special angles.

Along with the massive applications of the non-linear loads and the impact loads, many non-stationary stochastic signals such as harmonics, inter-harmonics, impulse signals and so on are introduced into the electric network, and these non-stationary stochastic signals have had effects on the accuracy of the measurement of electric energy. The traditional method like Fourier Analysis can he applied efficiently on the stationary stochastic signals, hut it has little effect on non-stationary stochastic signals. In light of this, the form of the signals of the electric network in wavelet domain will he discussed in this paper. A measurement method of active power based on multi-resolution analysis in the stochastic process is presented. This method has a wider application scope compared with the traditional method Fourier analysis, and it is of good referential value and practical value in terms of raising the level of the existing electric energy measurement.

Aiming at detecting Cl2 gas, this study was made on how to make In-based compound semiconductor oxide gas sensor. The micro-property and sensitivity of In-based gas sensing material were analyzed and its gas sensitive mechanism was also discussed. Adopting constant temperature chemical coprecipitation, the compound oxides such as In-Nb, In-Cd and In-Mg were synthesized, respectively. The products were sintered at 600 ℃ and characterized by the Scanning Electron Microscope （SEM）, showing the grain size almost about 50-60 nm. The test results show that the sensitivities of In-Nb, In-Cd and In-Mg materials under the concentration of 50 × 10^-6 in Cl2 gas are above 100 times, 4 times and 10 times, respectively. The response time of In-Nb, In-Cd and In-Mg materials is about 30, 60 and 30 s, and the recovery time less than 2, 10 and 2 min, respectively. Among them, the In-Nb material was found to have a relatively high conductivity and ideal sensitivity to Cl2 gas, which showed rather good selectivity and stability, and could detect the minimum concentration of 0.5 × 10^-6 with the sensitivity of 2.2, and the upper limit concentration of 500 × 10^-6. The power loss of the device is around 220 mW under the heating voltage of 3 V.

Luminance deficiency of road lighting is one of the primary reasons for night-driving risk. The randomness and uncertainty of accidents caused by luminance deficiency have increased due to vehicle liquidity, and it causes difficult in accident analysing and preventing. In order to ensure lighting safety for night-driving vehicles, according to relevance between lighting intensity and visibility and streetlamp location principle, MATLAB was used to optimize road lighting evenness model. Compared with optimization model analytical data, night luminance of forty-two main roads in Harbin was measured actually by TES-1336A digit luminance acquisition system. The model can effectively design parameters selection of road lighting. The standpoint that luminance evenness is one of the indirect reasons for traffic accident is provided in this paper. Then theoretical basis of streetlamps modification projects for visibility deficiency roads and night-driving accident analyse was established. Copyright ASCE 2007.

Efficient Path-Following for Urban Logistics: A Fuzzy control Strategy for Consumer UAVs under Disturbance Constraints

The adoption of consumer unmanned aerial vehicles (UAVs) for logistics transportation is a key aspect of the emerging low-altitude economy, yet it faces significant challenges. Urban environments introduce complex obstacles, including dense buildings and unpredictable wind disturbances, while existing control methods struggle to balance path-following accuracy, disturbance rejection, and communication efficiency. To meet these demands, this paper proposes a quantized fuzzy learning path-following control for consumer UAVs. Firstly, a hysteresis quantized fuzzy disturbance observer (HQFDO) is proposed where the disturbances are approximately estimated by a neural network. Notably, a hysteresis quantizer is employed to reduce the communication bandwidth occupation by discretizing disturbance observations. Subsequently, a distributed velocity controller and a heading angle controller are designed to tackle the geometric and dynamic tasks separately. Specifically, the velocity controller introduces a projective arc length error to mitigate inefficiencies and safety risks associated with frequent acceleration and deceleration switches. Compared to conventional techniques, the proposed approach improves transient performance, enhances path attractivity, and optimizes communication resource utilization. Theoretical stability analysis is provided, and simulations validate the effectiveness of the proposed control strategy. © 1975-2011 IEEE.
