It is important to develop low-cost, fast and portable meat adulteration detection systems to ensure the meat authenticity and safety in complex market environments. A multi-channel spectral detection system for meat adulteration was developed in this study. The core hardware of the system mainly includes a designed spectral module and a Raspberry pi controller. The spectral module consists of three multi-channel spectral sensors and LED lamps with specific wavelengths, containing 18 channels covering a range of 410–940 nm. The software was developed based on PyQt5. After completing the construction of the system, the detection distance was discussed and determined to be 4 mm. Based on the spectral data collected by the developed system, the models for classifying pure mutton, pure pork, mutton flavour essence adulteration, colourant adulteration and adulterated mutton with pork were established and compared. Four intelligent optimisation algorithms were further used to improve the model performance. The results of the test set showed that the support vector classification (SVC) model optimised by a sparrow search algorithm (SSA) obtained the best classification performance, with an accuracy of 97.59% and a Kappa coefficient of 0.9696. After the SSA-SVC was incorporated into the sensor software, the system performance was evaluated using external validation samples. The overall accuracy of the system was 94.29%. The system took about 5.31 s to detect a sample, and the total weight of the system was 1.55 kg. Overall, the developed portable spectral system has considerable potential to rapidly and accurately discriminate adulterated mutton in the field. • A portable and low-cost detection system for adulterated mutton was developed. • The spectral acquisition distance was discussed and determined using SID and SAM. • The PSO, GA, MPA and SSA were used to improve the performance of the SVC model. • The overall accuracy of the system for external validation samples was 94.29%. • The system only took about 5.31 s to complete the detection of a sample.

A digital twin-driven lifecycle management method is proposed to monitor the lifespan of motorized spindle. The lifecycle management system is designed and developed based on the combined programming of MATLAB, ANSYS, and LabVIEW. The prediction models of lifespan are built according to the digital twin (DT) data of thermal characteristics of the motorized spindle. The DT for thermal characteristics is realized through correcting the thermal boundary conditions according to the correction models which are established according to the measured and simulated temperatures at thermal key points. The temperature domain and threshold models of the cooling channel are constructed using the exponential fitting method to monitor the working status of the cooling system. The experimental results show that the DT-driven lifecycle management system can effectively monitor the status and remaining useful life of the motorized spindle, which provides a basis for the lifecycle management of the motorized spindle.

The architecture, engineering, and construction (AEC) industry in the US faces increasing labor shortages while accumulating downward productivity trends. Previous research efforts have shown that lack of timely access to information is one of the main factors hindering construction workers' productivity, and prompt information extraction (IE) from BIM sources can help address this issue. This study develops a BIM-web interoperable system, featuring a voice-based intelligent virtual agent (VIVA), to provide workers with information on-demand when conducting their activities on the jobsite. VIVA integrates construction digital sources with web platforms to enable real-time data communication between the users, workers in this case, and BIM platforms. The voice interaction feature of VIVA provides an intuitive and safe tool that can easily be used by workers with varying ranges of experience, with minimal need for training. The responsiveness and accuracy of VIVA is evaluated through two proof-of-concept case studies. Results indicate that the BIM-VIVA link and underlying natural language understanding (NLU) algorithms in the Google Actions platform accurately understand user queries, with a performance of 97.50% correct responses. As a result, VIVA achieves superior performance compared with previous research works based on NLU algorithms with text-based queries. The developments made in this research not only contribute to improving the safety and productivity of construction workers but also can open the door for easier onboarding of less-experienced workers, thus addressing the industry's severe skilled labor shortage issue. Practical Applications: This study introduces an innovative web-based system featuring VIVA to address the pressing labor shortage and diminishing productivity in the AEC industry. VIVA seamlessly integrates construction digital sources with web platforms, enabling real-time communication with construction workers and facilitating their on-demand information retrieval. The intuitive voice interaction feature of VIVA offers a safe and easily navigable tool that demands minimal training for workers with diverse backgrounds and experience levels. This feature also makes VIVA a practical tool for hands-free communication and information retrieval on jobsites, which minimizes the imposed distraction inherent in technological solutions. Construction workers can use voice commands to access project plans, schedules, and safety protocols, allowing them to retrieve critical information without having to stop work or use their hands. This intuitive interface reduces the need for complex user interfaces or manual input, making it easier for workers to interact with technology while focusing on their tasks. Hence, VIVA promises to improve productivity and safety of diverse group of workers without causing distraction or safety issues itself, which is a common concern when implementing technology to assist workers in hazardous and ever-changing construction jobsites. Beyond enhancing safety and productivity, widespread use of VIVA can help address the AEC sector's severe skilled labor shortage by providing an accessible means to onboard less-experienced workers. As such, VIVA provides opportunities to augment efficiency for seasonal/nonnative workers, thus facilitating the integration of a broader workforce and addressing the industry's pressing labor challenges.

Considering the shortcomings of the current monitoring system for tunnel anchor support systems, a tunnel anchor monitoring system based on LSTM-ARIMA prediction is proposed in this paper to prevent the deformation and collapse accidents that may occur in the underground mine tunnels during the backfilling process, which combines the Internet of Things and a neural network deep learning algorithm to achieve the real-time monitoring and prediction of the tunnel anchor pressure. To improve the prediction accuracy, a time series analysis algorithm is used in the prediction model of this system. In particular, an LSTM-ARIMA model is constructed to predict the tunnel anchor pressure by combining the Long Short-Term Memory (LSTM) model and the Autoregressive Integrated Moving Average (ARIMA) model. And a dynamic weighted combination method is designed based on model prediction confidence to acquire the optimal weight coefficients. This combined model enables the monitoring system to predict the anchor pressure more accurately, thereby preventing possible tunnel deformation and collapse accidents in advance. Finally, the overall system is verified using the anchor pressure dataset obtained from the 21,404 section of the Hulusu Coal Mine transportation tunnel in real-world engineering, whose results show that the pressure value predicted using the combined model is basically the same as the actual value on site, and the system has high real-time performance and stability, proving the effectiveness and reliability of the system.

The current paper describes the development of an online Collaborative Intelligent Individual Education Platform (CIIP) that is specifically designed for children with ASD based on experts' assessments and progress reports. The online platform facilitates the progress of children with special needs as it is established on their individual needs and can be accessible anywhere. The CIIP system was developed following a prototyping model approach that comprised initial requirements, design, prototyping, customer evaluation, review and refinement, development, testing, and maintenance. Two cycles of prototyping evaluation were conducted to confirm the final requirements. The results of the prototype evaluation by the stakeholders indicated that 29 changes were required before progressing to the final development of CIIP. System testing was carried out with expert testers to ensure the CIIP functions and the satisfaction of the expected requirements. The results showed that 22% of the test cases failed due to difficulties with complicated interconnections in several modules. Despite these challenges, CIIP was able to meet the requirement specifications and perform as expected. [ABSTRACT FROM AUTHOR]

In this paper, we describe a sheet-shaped throwable transforming robot. Sheet-type robots can change their shape to perform tasks according to the situation. Therefore, they are expected to be useful in places with many restrictions, such as disaster sites. However, most of them can only move slowly on the ground. Therefore, in order to actually deliver the robot to the disaster site, it must be carried manually. To solve this problem, we are developing a sheet-shaped robot that can be thrown from the sky. Previously developed prototypes could only move in the forward direction, and the transition from falling to walking was complicated and uncertain. In this paper, we report on a new prototype that improves on these shortcomings. [ABSTRACT FROM AUTHOR]

The object of this study is the dominant forms of investment capital and their convergence according to the stages of development of socio-economic systems. Any evolution has certain stages. The development of socio-economic systems is no exception. All processes and phenomena in the world, including development, occur cyclically and are interconnected with the stages of natural, social, and economic processes. According to the theory of economic cycles, such phenomena as the development of the socio-economic system, its crisis and innovations have a close relationship. Industrial revolutions became a vivid example of changes in the socio-economic development of complex systems. One of the main sources of financing for each stage of the industrial revolution is investment capital, which can be part of industrial, private, financial, banking, or intellectual capital. Depending on the signs of social relations, social system, etc. can take their forms. Each of the stages of the industrial revolution is preceded by appropriate conditions that are associated with certain historical conditions at a specific moment in time. Considering the dominant forms of investment capital according to the stages of the industrial revolution, the reasons for their change should be noted. The process of convergence of investment capital is considered here. One of the indicators that characterizes the efficiency of investment capital is its mobility or immobility. A number of macroeconomic factors affect the mobility of investment capital. Considering the world structure of direct foreign investments, the main directions of their utilization have been indicated. The model of the convergence of the dominant forms of investment capital in the logistics system is presented in accordance with the stage of the industrial revolution and the features that accompany it.

In badminton, accurate service height detection is critical for ensuring fairness. We developed an automated service fault detection system that employed computer vision and machine learning, specifically utilizing the YOLOv5 object detection model. Comprising two cameras and a workstation, our system identifies elements, such as shuttlecocks, rackets, players, and players' shoes. We developed an algorithm that can pinpoint the shuttlecock hitting event to capture its height information. To assess the accuracy of the new system, we benchmarked the results against a high sample-rate motion capture system and conducted a comparative analysis with eight human judges that used a fixed height service tool in a backhand low service situation. Our findings revealed a substantial enhancement in accuracy compared with human judgement; the system outperformed human judges by 3.5 times, achieving a 58% accuracy rate for detecting service heights between 1.150 and 1.155 m, as opposed to a 16% accuracy rate for humans. The system we have developed offers a highly reliable solution, substantially enhancing the consistency and accuracy of service judgement calls in badminton matches and ensuring fairness in the sport. The system's development signifies a meaningful step towards leveraging technology for precision and integrity in sports officiation. [ABSTRACT FROM AUTHOR]

During the past years, intelligent manufacturing has attracted enormous attention from both academia and industry. Smart factories/workshops/production lines are important carriers for realizing intelligent manufacturing. However, there are difficulties in smart factories in processing multi-source heterogeneous data, in integrating virtual and physical worlds, and in achieving continuous and iterative optimization with real-time feedback. Digital twin, which is able to deeply integrate physical and virtual worlds, provides an important technology for easing the difficulties mentioned above. The construction of a digital twin system can solve the problem of data fusion, analysis, processing, and applications in smart factory. Digital production lines are the foothold of a smart factory. Building a digital twin production line can facilitate rapid practice of digital twins and promote the development of intelligent manufacturing. To this end, this paper proposes a development framework for a digital twin production line with closed-loop control based on a mechatronics approach. The detailed development process is given based on the framework. The framework proposed may provide some inspiration and insights for design and development of digital twin production lines.

Under the coordinated mining mode of close-multiple coal seams, due to the mining influence between coal seams, the roof structural characteristics are different after each coal seam extraction, so the calculation methods of support resistance shield of each coal seam are also different. In order to provide ideas for the setting load of shield determination in each coal seam, the calculation methods of the support capacity of shield in each coal seam is given by comprehensive use of theoretical analysis, system development and field measurement. The results show that: ①The voussoir beam, given load of loose body and voussoir beam with given load of loose body balance roof structure models after each coal seam extraction are established. Voussoir beam balance roof structure model is applicable to the coal seams extractions that are not affected by mining or are less affected by mining. Given load of loose body balance roof structure model is applicable to the coal seams extractions with a single roof stratum and is affected by the upper coal seam extraction. Voussoir beam with given load of loose body balance roof structure model is applicable to the coal seams extractions with multi-rock strata and within has a thick and hard lithology. At the same time, affected by the extraction of the upper coal seam, the rock stratum can still maintain continuity and integrity. ②The “overburden breaking and load evaluation system for close-multiple coal seams extraction” suitable for Kailuan Group is developed, and the recommended selection results of setting load of shield in each coal seam are put forward. Through the field measurement of support capacity of shield, the load utilization rate of shield in each coal seam is generally low and the load margin of shield is too large after using the empirical selection results of the setting load of shield. After adopting the recommended selection results of the setting load of shield in each coal seam, the load utilization rate of shield in each coal seam is significantly improved and the load margin of shield is significantly reduced.
