For electric vehicles widely used recently, lithium-ion batteries serve as the primary energy storage units, affecting the vehicles’ performance, safety, and lifespan. Accurate state of charge (SOC) estimation is pivotal for the battery management system (BMS) to enhance the predictability of the vehicle’s range and avert thermal runaway due to improper charging methods. In this study, an adaptive SOC estimation methodology was developed using parameter identification with forgetting factor recursive least squares (FFRLS). These parameters are then incorporated into a dual adaptive extended Kalman filter (DAEKF) for SOC estimation under varying load conditions. DAEKF is used to dynamically adjust the covariance matrices for process and measurement noises, significantly enhancing the filter’s adaptability and precision. The integration of FFRLS and DAEKF enables a robust SOC estimation of electric vehicles, featuring rapid computation speeds, high accuracy, and excellent adaptability, positioning them as ideal candidates for enhancements in battery management system technology.

Hard thresholding is a common method for denoising wavelet coefficients. However, determining an optimal threshold remains challenging. Therefore, we propose an adaptive hard threshold that accounts for the size of the noisy image based on the statistical properties of the wavelet coefficient. Regression analysis is used to determine the adaptive threshold to ensure effective performance with multiresolution wavelet coefficients. The adaptive threshold enables a balance between denoising and high-frequency detail preservation, and excellent denoising performance. Multiple segmentations are conducted using the multiresolution properties of the wavelet transform, based on both image size and noise level, leading to the best denoising results. Full article

We developed an artificial intelligence (AI) player for Drawing Werewolf, a multiplayer game involving collaborative sketching and hidden roles. Players contribute to a shared drawing while identifying a secret “Werewolf” unaware of the theme. AI, trained with SketchRNN on the “Quick, Draw!” dataset, mimics human behavior by generating theme-relevant sketches. The game was built with C++ and supports real-time human–AI interaction via sockets. Initial experiment results confirmed AI’s ability to participate and draw appropriately. The remaining challenges, including improving strategic voting, theme inference, and context-aware drawing, need to be addressed. Full article

For the detection of structural cracks, engineers need to conduct measurements on-site. However, structural cracks are widely distributed and are not easy to access for measurement. Therefore, photography is commonly used for crack detection. Although the crack is observed in the photos, its location and size need to be clearly defined. Artificial intelligence (AI) and databases are used in graphic processing methods to perform structural crack analysis, in which the Python 3.12 program is used as the main tool. Using the Python program, an AI image analysis program was developed for crack analysis and evaluation. ChatGPT 3.5 was also used for the analysis of crack length and width. Using AI considerably increased credibility in detecting and measuring structural cracks. Full article

Chemical vapor deposition (CVD) is a high-precision thin-film fabrication technique that is widely applied in semiconductor manufacturing, optical component manufacturing, and materials science. The performance of the deposition process plays a critical role in determining the quality of the final product. However, multiple variables in CVD processes have a highly nonlinear nature that involves complex interactions. Therefore, conventional experimental methods exhibit limitations in quality control and process optimization for CVD. In this study, we developed a predictive model based on process parameters and quality indicators using machine learning techniques to analyze and optimize the CVD processes. Through data collection, feature selection, model training, and model validation, the developed machine-learning algorithms were tested and evaluated. The adopted machine learning algorithms effectively captured the nonlinear relationships between multiple variables in CVD processes, accurately predicted thin-film quality indicators, and provided data for optimizing process parameters. In addition, the analysis results of feature importance revealed the effect of each key parameter on product quality, offering a basis for process improvement. Overall, the results of this study highlight the capability of machine learning algorithms for quality control and optimization in CVD processes for future advancements in smart manufacturing.

Accurate tumor segmentation is crucial for cancer diagnosis and treatment planning. We developed a hybrid framework combining complementary convolutional neural network (CNN) models and advanced post-processing techniques for robust segmentation. Model 1 uses contrast-limited adaptive histogram equalization preprocessing, CNN predictions, and active contour refinement, but struggles with complex tumor boundaries. Model 2 applies noise-augmented preprocessing and iterative detection to enhance the segmentation of subtle and irregular regions. The outputs of both models are merged and refined with edge correction, size filtering, and a spatial intensity metric (SIM) expansion to improve under-segmented areas, an approach that achieves higher F1 scores and intersection over union scores. The developed framework highlights the potential in combining machine learning and image-processing techniques to develop reliable diagnostic tools. Full article

Chazence is a subsidiary of Zence Object Technology Company in the Greater Bay Area of China. It is a sustainable enterprise that combines tea industry consumables (tea residue) with fiber composite technology to replace traditional materials and conduct product practices. Their core philosophy aligns with the United Nations’ Sustainable Development Goals (SDGs), particularly Goals 9 and 12, emphasizing industrial innovation, the sustainable management of natural resources, and the promotion of sustainable consumption and production patterns. However, the current system of tea recycling is extensive and requires precise data management and back-end human resource allocation to ensure efficient collaboration between professionals and grassroots staff. Currently, the system does not have a user-friendly interface for human resource allocation, data management, resource management, and visual information. Therefore, we optimized the interface and functional design of the warehouse system to improve the efficiency of resource management of Chazence by understanding its approach to tea recycling. Through surveys and interviews, employee needs and user experiences were analyzed, and the results guide the design of a sustainable enterprise management system from a user experience (UX) perspective.

Watermelon is a popular fruit, predominantly cultivated in Asian countries. However, the production and harvesting processes present several challenges. Due to its size and weight, manually harvesting watermelons is labor-intensive and costly. In the future, technology is expected to enable robots to harvest watermelons. Therefore, it becomes essential to introduce intelligent systems to effectively identify and locate watermelons in harvesting. This research aims to develop an advanced methodology for watermelon identification and location using You Look Only Once (YOLO)v8 and YOLOv8-oriented bounding box (OBB) algorithms. Furthermore, the simple online and real-time tracking (SORT) algorithm was employed to track and count watermelons and estimate yield. The performance of YOLOv8-OBB was better than that of YOLOv8 and the highest precision (0.938) was achieved by YOLOv8s-OBB. Additionally, the size of each watermelon was measured with both models. The models help farmers find the optimal watermelons for harvest. Full article

Physically simulated attack experiments were conducted using LED lights of different colors, the You Look Only Once (YOLO) v5 model, and the German Traffic Sign Recognition Benchmark (GTSRB) dataset. We attacked and interfered with the traffic sign detection model and tested the model’s recognition performance when it was interfered with by LED lights. The model’s accuracy in identifying objects was calculated with the interference. We conducted a series of experiments to test the interference effects of colored lighting. The attack with different colored lights caused a certain degree of interference to the machine learning model, which affected the self-driving vehicle’s ability to recognize traffic signs. It caused the self-driving system to fail to detect the existence of the traffic sign or commit recognition errors. To defend from this attack, we fed back the traffic signs into the training dataset and re-trained the machine learning model. This enabled the machine learning model to resist related attacks and avoid disturbance. Full article

Energy conservation and carbon reduction are critical in energy policies. Therefore, numerous energy-saving methods, such as the introduction of new technologies and the replacement of outdated equipment, have been proposed. To determine whether these methods are effective in energy conservation and carbon reduction, scientific validation is required. The most common validation method is energy baseline. An energy baseline refers to the use of data measured before energy-saving improvements. It is used to construct a mathematical model that describes energy consumption. Using the baseline, the energy consumption during the baseline period after improvements is calculated. By subtracting the measured consumption from the value, the amount of energy saved is estimated. Traditionally, linear regression is used to establish energy baseline prediction. However, linear regression has limitations with complex energy data. Therefore, we used deep learning models to handle nonlinear data in the air compression system for comparative analysis. The developed long-short-term memory (LSTM) model showed superior capabilities for processing nonlinear data, aligning with the actual data distribution, and reducing errors. Compared with linear regression models, the LSTM model reduced uncertainty, risk, and cost by 40.3%. Full article

We developed a machine-learning model for the International Classification of Diseases, 10th Revision (ICD-10) classification using data from 5108 patients. Nine features, including age, gender, BMI, and vital signs, were extracted to classify the top three ICD-10 categories: intestinal infections, tuberculosis, and other bacterial diseases. Decision trees, random forest, and XGBoost models were tested using the synthetic minority over-sampling technique (SMOTE) and class weights to minimize class imbalance. Five-fold cross-validation was used using the training and testing datasets in a data ratio of 80:20. The random forest model with class weights showed the best performance. Shapley additive explanations (SHAP) analysis highlighted body-mass index (BMI), gender, and pulse as key features.

Accurate indoor localization is vital for smart environments and the Internet of Things (IoT) applications. Received signal strength indicator (RSSI)-based methods suffer from multipath fading, signal attenuation, and missing data. To address these issues, we developed quantum random forest indoor localization (QRF-IL), a quantum-inspired machine learning method that combines quantum random forests (QRFs) with weighted centroid regression. Each quantum decision tree in QRF uses a quantum support vector machine (QSVM) with Nyström quantum kernel estimation for efficient and accurate learning. On a public dataset, QRF-IL showed an average localization error of 2.3 m, which was reduced by 9% over a standalone QRF model and 21% over an adaptive path loss model (ADAM). Full article

Virtual reality (VR) has emerged as a transformative tool in the treatment of phobias and the cultivation of emotional resilience. This study aims to explore the potential of VR to create controlled, immersive environments that facilitate exposure therapy, enabling individuals to confront and desensitize themselves to their fears in a safe and personalized manner. The flexibility of VR systems allows therapists to tailor scenarios to the unique needs of patients, addressing specific phobias such as acrophobia, arachnophobia, and social anxiety disorders. Beyond phobia treatment, VR’s capacity to simulate challenging or stress-inducing scenarios presents opportunities for fostering emotional resilience by building adaptive coping mechanisms and reducing stress responses over time. The integration of biofeedback and machine learning further enhances VR applications, enabling real-time adjustments based on physiological and psychological responses. In this article, the current advancements, underlying mechanisms, and challenges in leveraging VR technology for therapeutic purposes are discussed with a focus on its implications for mental health care. By combining immersive technology with evidence-based practices, VR offers a promising pathway for improving mental health outcomes and expanding the accessibility of therapeutic interventions.

With globalization and technology advancement, traditional teaching models are facing challenges due to the diverse needs of modern learners. It is necessary to enhance learner engagement and motivation, and incorporating Internet of Things (IoT)-assisted teaching tools has become a major concern for educators. However, the time it takes to develop new teaching tools and integrate IoT technology must be shortened by combining educational content with game mechanics seamlessly. Therefore, we developed a gamified teaching model by incorporating IoT technology. We used the “System, Indicators, Criteria” framework to develop a three-tiered board game evaluation and development model. Based on this framework, a teaching tool was designed to provide personalized learning experiences with IoT technology. The tool provides abstract knowledge, fosters interaction and collaboration among learners, and thus enhances engagement. To ensure a rigorous design and evaluation process, we employed quality function deployment (QFD), analytic hierarchy process (AHP), and fuzzy comprehensive evaluation (FCE). The developed model facilitates the integration of IoT technology with innovative design concepts and enhances the application value of teaching tools in education. The model also enhances intelligence, interactivity, and creativity for traditional education to revitalize learning experiences. Full article

Autonomous driving technology is developing rapidly, particularly in vision-based approaches that rely on cameras to monitor the environment. However, one of the critical challenges for autonomous vehicles is the ability to adapt to different weather conditions, as environmental factors such as clouds, fog, rain, sand, shine, snow, and the sunrise significantly impact their perceptual capabilities. Control strategies of the vehicles must be dynamically adjusted based on real-time weather conditions to ensure safe and efficient driving. For the strategies, we developed a novel weather perception model to improve the adaptability of autonomous driving systems. The model is more lightweight than an existing study, as it is computationally efficient with enhanced performance. Moreover, the model detects a weather type, improving its robustness, and providing reliable weather awareness for autonomous driving. Full article

Structural parameters, such as strain or deflection, were collected by sensors and analyzed to assess the bridge’s structural condition and obtain a reliable reference for bridge maintenance. In the data acquisition and transmission process, sensor data inevitably contains noise and interference, resulting in anomalies, especially data distortion during wireless transmission. These anomalies significantly impact data analysis and structural evaluation. To mitigate the effects of these abnormalities, we conducted the cause analysis. The Sanxia Viaduct was used to design a strain monitoring method as a bridge model. We analyzed vibrating string sensor data collected in the cold environment using the Nair method to eliminate outlier data. The analysis results of strain and temperature trends showed that the data fusion method developed in this study showed high precision and stability and effectively reduced the impact of noise and data anomalies. By monitoring actual bridges, the effectiveness and practicality of the method were validated. The model provides significant information on the development and application of bridge health monitoring technology. Full article

The radiofrequency identification (RFID) interface is used in a controller area network (CAN) bus system to enhance the performance of stacked fuel cells. In addition, a personal computer base logic analyzer (LA) is utilized to monitor and analyze data transmitted over the CAN bus. The LA enables the visualization of digital signals, identification of data patterns, and troubleshooting of communication protocols. The combination of the CAN bus with the RFID interface and LA provides an effective solution for testing and monitoring digital communication systems. The result of this study proves that LA is applied in series-connected fuel cells. The advantages of the RFID CAN bus are validated by modern communication protocols. Full article

We fabricated TiO2 thin films using the sol–gel method, incorporating TiO2 nanoparticle sizes of 25 nm on the fluorine-doped tin oxide (FTO) substrates by spin coating and annelation at 600 °C. The influence of incorporating TiO2 particles on the surface morphology, optical properties, and photovoltaic performance of TiO2 thin-film dye-sensitized solar cells (DSSC) was examined. Structural characterization was analyzed using X-ray diffraction (XRD), while the morphologies were analyzed using scanning electron microscopy (SEM). The transmittance and absorbance of films were measured using an ultraviolet (UV)–visible (VIS)–near-infrared (NIR) spectrophotometer. The current–voltage (I-V) property was evaluated under simulated solar irradiation. The results demonstrated that the incorporation of TiO2 particles enhanced the efficiency of DSSCs. The photovoltaic performance of DSSCs was improved with TiO2 nanoparticle incorporation. The optimized DSSC incorporated TiO2 films (TIFNA). TIFNA achieved a Jsc of 14.49 mA/cm2, Voc of 0.69 V, fill factor of 60.5%, and efficiency of 6.05%, compared to 4.23% for the DSSC with unincorporated TiO2 thin film. The improved performance was attributed to increased dye adsorption, better crystallinity, and enhanced electron transport. Full article

Artificial intelligence (AI) and big data technology were applied to assess carbon emissions in a high-tourism area in this study. In the study site, the Thalang Road in Phuket Old Town, Thailand, visitors and vehicles (including cars, motorcycles, trucks, vans, and Tuktuks) were counted using closed-circuit television (CCTV) footage and classified via the real-time detection transformer (RT-DETR) algorithm. The data were combined with records of electricity usage. From March to October 2024, 20,000 visitors per month visited the site. Electricity was the main source of carbon emissions, averaging 88 ± 11 tCO2-eq monthly. Transport accounted for 500 ± 14 kg CO2-eq. The average emission per visitor was calculated as 4.2 ± 0.4 kg CO2-eq. The results showed how sustainable tourism policies and urban planning strategies need to be developed in Phuket. Based on the results, indirect emissions from the site need to be estimated. Full article

With the rapid development of the Internet of Things (IoT) applications, the ability to automatically discover and retrieve resource information has become increasingly enhanced. Despite being one of the most commonly used IoT communication protocols, Message Queuing Telemetry Transport (MQTT) does not natively support resource discovery. To address this limitation, MQTT-resource discovery (MQTT-RD), a resource discovery mechanism based on MQTT, has been used for resource management. In this study, we tested and evaluated MQTT-RD using the Sniffer system that manages the resource directory and synchronizes data via MQTT. When too many Sniffers are activated, the MQTT-RD system becomes unsustainable. However, the experimental results in this study revealed that frequent updates to the resource directory (RD) and high-frequency heartbeat messages (pingalive) significantly increase network traffic and system load. In this study, we identified performance and stability issues to propose improvement strategies, including refining the topic design, reducing message transmission frequency, and improving the synchronization mechanism. Additionally, the feasibility of incorporating centralized management was explored to enhance system efficiency. Full article

With the increasing deployment of large language models (LLMs) in diverse applications, security vulnerability attacks pose significant risks, such as prompt injection. Despite growing awareness, structured, hands-on educational platforms for systematically studying these threats are lacking. In this study, we present an interactive training framework designed to teach, assess, and mitigate prompt injection attacks through a structured, challenge-based approach. The platform provides progressively complex scenarios that allow users to exploit and analyze LLM vulnerabilities using both rule-based adversarial testing and Open Worldwide Application Security Project-inspired methodologies, specifically focusing on the LLM01:2025 prompt injection risk. By integrating attack simulations and guided defensive mechanisms, this platform equips security professionals, artificial intelligence researchers, and educators to understand, detect, and prevent adversarial prompt manipulations.

We developed a machine learning model for disease classification based on the International Classification of Diseases, 10th Revision (ICD-10) codes, analyzing male and female groups using seven features. The three most prevalent ICD-10 classes covered over 98% of the data. Features were selected using the least absolute shrinkage and selection operator, ridge, and elastic net, followed by the mean decrease in accuracy and impurity. A random forest classifier with five-fold cross-validation showed improved performance with more features. Using Shapley additive explanations, age, BMI, respiratory rate, and body temperature were identified as key predictors, with gender-specific variations. Integrating gender-specific insights into predictive modeling supports personalized medicine and enhances early diagnosis and healthcare resource allocation. Full article

Environmental, social, and governance (ESG) has become a concern for companies, investors, and regulators. Its significance cannot be underestimated, as stakeholders increasingly demand accountability and transparency regarding corporate practices in these areas. Government agencies enforce laws mandating companies adhere to established ESG standards in response. However, despite these regulatory pressures, several obstacles have hindered organizations from effectively implementing sustainability initiatives, often resulting in lackluster outcomes. In this study, we developed a framework to implement ESG principles across various companies, utilizing the critical success factor (CSF) theory. By incorporating the perspectives of stakeholders, we identified the essential elements to achieve ESG. The developed framework in ESG studies employed the hybrid Delphi technique and the analytical hierarchy process (AHP), a structured method for organizing and analyzing complex decisions. Based on the results obtained from targeted questions, variables that influence ESG performance were identified. The effectiveness of different sustainability initiatives was also assessed to understand stakeholder engagement strategies and evaluate the impact of organizational culture on ESG adoption.

Quick User Datagram Protocol Internet Connection (QUIC) is a modern transport protocol leveraging the User Datagram Protocol (UDP) to improve latency, security, and mobility. In this study, we analyzed QUIC traffic by uploading a 10 MB file under varied maximum transmission unit (MTU), bandwidth, and segment size conditions. Interarrival times (IAT) at both client and server were captured and analyzed using ordering points to identify the clustering structure (OPTICS) clustering and Markov modelling. Transition matrices and eigenvalue spectra revealed steady states, convergence behavior, and spectral gaps. The results showed that parameter variations significantly affected the traffic state diversity and flow dynamics, optimizing QUIC performance in real-world deployments. Full article

Traditional high-utility itemset (HUI) mining methods tend to overestimate utility for long itemsets, leading to biased results. High average-utility itemset (HAUI) mining addresses this problem by normalizing utility with itemset length. However, uniform utility thresholds fail to account for varying item importance. Recently, HAUI mining with multiple minimum utility thresholds (MMU) has been used for flexible utility evaluation. While the generalized HAUIM (GHAUIM) algorithm performs well, it requires two database scans and is limited to static datasets. Therefore, we developed a novel tree-based method that scans the database only once to improve efficiency by reducing storage and eliminating costly join operations. Additionally, pruning strategies and incremental updates were introduced to enhance scalability. The developed method outperformed GHAIM in efficiency. Full article

Amid expanding higher education and enhancing spatial quality, modern university campuses face challenges including inefficient space utilization and a disconnect from human-centered design. We developed a coupled model that integrates the analytic hierarchy process (AHP) with space syntax theory to identify and address functional fragmentation, limited accessibility, and diminished spatial vitality. The Delphi method was employed to determine weights on visual and traffic influence factors. Through spatial quantitative analysis using Depthmap software, we estimated spatial-efficiency discrepancies across 11 component types, including school gates, teaching buildings, and libraries. A case study was conducted at a university located in the hilly terrain of Conghua District, Guangzhou, China which revealed significant contradictions between subjective evaluations and objective data at components, such as the administrative building and gymnasium. These contradictions led to poor visual permeability, excessive path redundancy, and imbalanced functional layouts. Based on the results of this study, targeted optimization strategies were proposed, including permeable interface designs, path network reconfiguration, and the implementation of dynamic functional modules. These interventions were tailored to accommodate the humid subtropical climate, balancing shading, ventilation, and visual transparency. In this study, methodological support for the renovation of existing campus infrastructure was provided as theoretical and technical references for space renewal in tropical and subtropical academic environments and the enhancement of the quality and resilience of campus spaces. The results also broadened the application of interdisciplinary methods in university planning. Full article

Wireless sensor networks (WSNs) consist of distributed sensor nodes deployed for real-time monitoring and data collection. Optimizing sensor energy consumption is critical for extending the overall network lifespan. In large-scale WSNs, clustering techniques are required to reduce energy consumption. Many effective clustering methods have been proposed, but finding the optimal number of clusters in an energy-efficient manner remains challenging. Swarm intelligence (SI) algorithms help solve this problem, but testing all possible cluster configurations is computationally expensive. Neural networks excel in identifying hidden patterns in data, making them a promising tool for this task. However, training an AI agent to accurately predict both the number of cluster heads (CHs) and their locations is difficult. In this study, we developed a synergic method by employing a reinforcement learning (RL) model to predict the number of CHs while utilizing an SI algorithm to identify the most appropriate nodes to become CHs. This approach minimizes transmission energy and prolongs the lifespan of WSNs and their services. Full article

Quick-response (QR) codes are widely used for information transmission. However, their black-and-white dot structure often lacks visual appeal. Therefore, we developed novel graphic QR codes that remove traditional corner finder patterns and conceal data within redesigned modules. These codes can be scanned, positioned, and decoded directly in software, while paper-based versions can be instantly decoded by overlaying a transparency with printed finder patterns. Experimental results across varying grayscale levels and devices confirmed reliable readability. The proposed QR codes provide enhanced esthetics and security, offering a new direction for future QR code applications. Full article

As manufacturing technology advances, the shift toward smart solutions makes programmable logic controllers (PLCs) essential due to their reliability and scalability. Operational failures cause major disruptions if not detected early. Therefore, we developed an improved fault and behavior monitoring tool for programmable logic controllers (IFBMTP) to detect Type I and II errors using Boolean and analog signals. The tool addresses the problems caused by power load variations and complex power signals. The developed PFBMTP enables accurate power signal analysis and fault detection. We simulated different systems to model various fault scenarios, enabling early-stage detection through current and voltage monitoring. This approach overcame the limitations of physical hardware testing, allowing efficient, repeated validation across dynamic manufacturing environments. By integrating multiple technologies on a virtual platform, PFBMTP enhanced diagnostic accuracy, saved costs, and ensured process reliability in deployment. Full article

We developed and evaluated a monitoring and control system based on the controller area network (CAN) bus with a microprocessor of Arduino UNOs and a logic analyzer as auxiliary tools. We implemented a CAN bus communication system using Arduino UNO to control servo movements and collected data from ultrasonic sensors, infrared (IR) sensors, or DHT11 sensors that measure temperature and humidity. The CAN node received the data to control the servo motor and to display the information on the liquid crystal display. While the IR sensor detects an object, the ultrasonic measurement is stopped, and the servo is set to the home position at 0°. The CAN bus communication operated effectively, enabling real-time control of the servo motor following the command from sensor data. Full article

High-utility itemset mining (HUIM) utilizes the threshold value to extract HUI from the transactional database. However, it is difficult to define an optimal threshold value, since it depends on the domain knowledge of the application. Therefore, top-k HUIM is used to solve the problem of setting a threshold. A user can define a k value, which represents the number of HUIs. Moreover, there exist itemsets occurring at a specific time interval, which can become HUI. Since the traditional HUIM algorithm does not consider the transaction with the time interval, the HUIM algorithm cannot be used directly. Therefore, high-on-shelf-utility itemset mining (HOUIM) is used to address the above problem in this study. The proportion of the utility value of the item in all of the time intervals with the itemset is used for determining whether the itemset is HOUI or not. In the top-k HOUIM, the KOSHU algorithm is used based on the data structure, ignoring the item with the negative profit in overestimating the utility of the itemset. The KOSHU algorithm needs less processing time. However, the KOSHU algorithm has to scan the database twice and sort the database once. Therefore, we developed an efficient algorithm based on the TIPN table to mine top-k HOUIs. The developed data structures include TIPN and MINC tables, IO Bitmap, and TIUL. In the TIPN table, we recorded positive items, positive utilities, negative items, and negative counts. The MINC table is used for storing the local/global counts of all of the items with negative profits. In the algorithm, we scanned the database only once. The developed algorithm is more efficient than the KOSHU algorithm. Full article

As global obesity rates rise, cardiovascular diseases increase, and stress-related issues become more severe. This increases the public awareness of health and exercise. However, existing spinning fitness equipment lacks personalized customization for individual needs. To address this, we developed a smart customizable spinning system that enables health monitoring, central computation, flywheel, voice interaction, notification, and query subsystems. Users can set fitness goals based on their personal needs, monitor workout data via sensors, and utilize voice interaction and control to track their exercise status in real time. The system notifies users of workout progress through a buzzer and message queuing telemetry transport, while the Web interface provides access to past workouts and health records. Additionally, the system supports bilingual functionality (Chinese and English), allowing users to operate it in their preferred language, enhancing global usability. Full article

In this study, selective intersection flow (SIF), a lightweight optical flow algorithm, was used to enhance efficiency and accuracy by filtering out non-contributive pixels. SIF, derived from the differential category of algorithms, is used to compute optical flow by analyzing intersections of equations from selected pixels rather than solving for all pixels. It replaces warping with a minimal computational procedure for initial flow estimate and employs a sliding window for optimized single-core performance. SIF runs 1.7–1.8 times faster and achieves 1.2–1.4 higher accuracy than the single iteration of the Lucas–Kanade method, showing promise for real-time micro drone navigation. Full article

By employing computational fluid dynamics (CFD) software (Ansys Fluent), we examined the thermal effects of vertical solar panels on the south-facing facades of mid-rise (50 m) and high-rise (100 m) buildings in a 5 × 5 idealized urban environment. Four configurations were analyzed in this study: no installation, evenly distributed, concentrated, and panels on both sides. Vertical solar panel installations were affected by building temperatures and pedestrian-level thermal environments. In the leeward streets of central buildings, pedestrian-level temperatures progressively increased by row, with the even distribution showing significant heat accumulation. For 100 m buildings, the average temperature under the even distribution configuration increased from 35.6 °C (no panels) to 39.5 °C (a difference of 3.9 °C, approximately 10.96%). Full article

With the advancement of medical care technology, the aging population has become a serious problem, and long-term care for the elderly is a major concern facing today’s society. Long-term care institutions take care of people with dysfunction or difficulties and provide them with continuous assistance. However, the shortage of specialists and the relative increase in costs have affected the burden on families. Long-term care has developed from traditional approaches to advanced ones at well-equipped facilities. We combine network technology with long-term care service with sensors that have alarm functions according to diverse needs, so that the elderly can receive complete care. Full article

The confluence of computer vision and natural language processing has yielded powerful vision language models (VLMs) capable of multimodal understanding. We applied state-of-the-art VLMs for quality monitoring of the shoe assembly industry. By leveraging the ability of VLMs to jointly process visual and textual data, we developed a system for automated defect detection and contextualized feedback generation to enhance the efficiency and consistency of quality assurance processes. We conducted an empirical evaluation by evaluating the effectiveness of the developed VLM system in identifying standard procedures for assembly, using the video data from a shoe assembly line. The experimental results validated the potential of the VLM system in detecting the quality of footwear assembly, highlighting the feasibility of future practical deployment in industrial quality control scenarios.
