This study develops an end-to-end load analysis scheme for flap and slat actuators, which comprise the aircraft’s high-lift system, and the analysis results are directly integrated into hardware optimization. Because they shoulder heavy responsibilities during the takeoff and landing phases, whether they can remain rock-solid under complex aerodynamic conditions or even remain unmoved in emergencies is directly related to their overall safety performance. This work process is closely linked and includes three major links. First of all, according to the CCAR-25.301 standard, the load envelope under normal working conditions is sorted out, and the limit cases of abnormal faults are exhausted. Subsequently, ANSYS Workbench pulled silk and peeled off the cocoons to capture the peak stress at the engagement between the output shaft and the gear. In the end, the closed-loop verification of the customized test bench made the theoretical calculations and the hardware-measured data exactly the same. The entire package provides designers with hardcore data support, and always uses airworthiness, not convenience, as the criterion when improving actuator performance.

Product options are an important means for civil aircraft manufacturers to meet market demand, increase revenue, and enhance competitiveness. How to achieve a customized configuration of civil aircraft options is the focus of attention for aircraft manufacturers. In order to reduce manufacturing costs and cover more target markets, it is necessary to pay attention to the customized detail design of aircraft products in the early stages of design. At present, academic research on product selection is relatively limited and lacks quantitative evaluation methods. This article selects four elements to form an evaluation indicator system, namely comfort, competitiveness, cost investment, and maintainability; establishes a civil aircraft option evaluation model based on grey correlation analysis, quantifies the degree of correlation between product options and customer needs, and uses the analytic hierarchy process to reflect the weight differences of evaluation indicators. Taking the option list of a wide-body aircraft as an example, the model was used to evaluate and rank the options, verifying the rationality of the model and providing a reference for aircraft manufacturers to make provisions in advance.

As a densely populated public place, exhibitions feature spatial layouts with multi-area linkage and instantaneous crowd flow mutations. Thus, developing a crowd flow early warning system adapted to exhibition dynamics is a key focus at the public safety and smart exhibitions to avoid risks like local congestion-induced stampedes. In general, two core challenges in exhibition crowd counting: 1) Key dynamic gathering information is hidden in high frequency components, but no correlation mechanism between frequency components and scene has been established; 2) Instant crowd gatherings cause high-frequency local density mutations, leading to time delays and spatial ambiguity of dynamic signals. To solve these, we propose a novel Crowd Counting Network for Risk Early Warning in Exhibition Scenarios with two core modules: 1) A bidirectional feature filtering module optimizes frequency information through low-frequency suppression to reduce redundancy and high-frequency activation to enhancing dynamic signals. 2) A lightweight self-attention module captures long-range dependencies of high-frequency features via frequency-domain self-attention, enabling accurate identification of feature clusters from gatherings. Validated on datasets like ShanghaiTech and UCF-QNRF, this method provides an integrated solution for exhibition security monitoring, promoting crowd counting technology from general scenarios to industry customization.

The shared autonomy framework has become an option with great potential in the field of autonomous vehicles. Human and machine control decisions typically demonstrate strengths in different scenarios. As a result, the robustness of systems can be enhanced by the collaboration between humans and autonomy. A shared autonomy architecture that takes into account both human and environmental factors was proposed in this work. The authority distribution between the human operator and the autonomy algorithm was determined by the Shared Autonomy Arbiter (SAB). Designed with a two-tier structure, the SAB incorporated a policy-level decision module, as well as a numerical-level arbitration tuning module. A fuzzy inference system (FIS) was incorporated to enhance the noise tolerance of the policy selection module. Furthermore, the human factor was taken into account by applying a projection to the users’ control input. The human operator’s control decision was projected by the Adaptive Personalized Control System (APeCS) to accommodate the skill levels and habits of various users. By incorporating a broad set of factors, this framework is suitable for diverse applications that require robustness in complex environments. Two case studies were included in this work to demonstrate its effectiveness. The first presented a concept design illustrating the application of the proposed architecture on autonomous vehicles operating in varied environments. The second showed that the proposed architecture can serve as a robust testbed by taking advantage of the authority modulating mechanism. By connecting a system under assessment and an established autonomy algorithm to the SAB, the new system can be tested robustly and safely through the flexible authority distribution.

The characteristic representation and in-depth understanding of driver personalized driving behavior are fundamental to achieving human-like autonomous driving, enhancing the rationality of autonomous driving decisions, and meeting passengers’ personalized needs. [ADDED]Personalized driving behavior refers to individual-specific patterns in vehicle operation that emerge from drivers’ unique combinations of skills, risk tolerance, and habitual responses.However, current research lacks consideration of cluster analysis in the feature representation stage and ignores the time-varying contribution degree of time series values to low-dimensional features, which inhibits further utilization and development. This study adopts deep embedding clustering method and introduces attention mechanism to investigate driver personalized high-speed lane change behavior.[ADDED] Using a comprehensive driving simulator platform, we collected 15-channel time series data from 12 drivers performing 216 lane changes across 18 controlled scenarios. The research establishes a joint optimization framework that simultaneously learns feature representation and cluster assignment through a variable joint objective function. Results show that compared with baseline methods, the features characterized by this method are closest to the original data after reconstruction. The clustering results demonstrate high intra-cluster compactness, large inter-cluster distances, and clear cluster shapes with significant differences among categories, facilitating personalized driving behavior classification. Model validation on multi-channel temporal classification datasets confirms the efficiency of the proposed model and effectiveness of attention mechanism integration with deep embedding clustering. This study reveals the superiority of attention deep embedding clustering method in the field of driver personalized driving behavior analysis and provides new directions for future research in intelligent vehicle development.

Automotive wooden interiors are increasingly popular among consumers for their excellent appearance and texture. However, low light transmittance limits their application in automotive interior smart surfaces. This study explores light transmission technology for wood veneer in automotive interiors, proposing two solutions based on the properties of wood veneer: the light-transmitting veneer solution and the laser-engraved beacon solution. Both solutions were tested through production experiments to evaluate the light transmission effects and process feasibility. Experimental results show that the light-transmitting veneer solution significantly improves the light transmittance of wood veneers through material modification, but instability in structure and materials leads to the difficulty of presenting a better light transmission effect. In contrast, the laser-engraved beacon solution achieves clear and stable light transmission effects by directly processing light-transmitting beacons on the veneer, effectively avoiding interference from surface paint. To further address the issue of veneer fragility around the beacon areas, the solution was optimized, and the laser-engraved micro-perforated beacon solution was proposed. After testing, the optimal micro-perforation diameter (0.25 mm) and micro-perforation spacing (0.25 mm) were finally determined for the laser-engraved micro-perforated beacon solution. This research provides innovative solutions for the application of wood veneer in automotive interiors, promoting the personalization and intelligence of automotive interior design.

The escalating complexity at intersections challenges the safety of the interaction between vehicles and pedestrians, especially for those with mobility impairments. Traditional traffic control systems detect pedestrians through costly technologies such as LiDAR and radar, limiting their adoption due to high costs and static programming. Therefore, the article proposes a customized signalized intersection control (CSIC) algorithm for pedestrian safety enhancement. This algorithm integrates advanced computer vision (CV) algorithms to detect, track, and predict pedestrian movements in real time, enhancing safety at a signalized intersection while remaining economically viable and easily integrated into existing infrastructure. Implemented at a key intersection in Bellevue, the CSIC system achieves a 100% pedestrian passing rate while simultaneously minimizing the average remaining walk time after crossings. The algorithm used in this study demonstrates the potential of combining CV with traditional traffic control mechanisms to create safer urban traffic environments for all road users.

The global medical device manufacturing industry is undergoing a rapid transformation driven by technological innovation, automation, and increasing demands for customized, high-quality care. For engineers at the heart of medtech manufacturing, understanding the latest technologies is crucial not only for maintaining competitiveness but also for ensuring regulatory compliance, improving time to market, and optimizing production workflows.
Thermoplastic fiber-reinforced polymer composites (TPC) are gaining relevance in aviation due to their high specific strength, stiffness, potential recyclability and the ability to be repaired thanks to their meltability. To maximize their potential, efficient repair methods are needed to maintain aircraft safety and structural integrity. This article introduces a novel repair technique for damaged TPC structures, involving the joining of a repair patch with induction welding using a susceptor material. The susceptor consists of a material with high electrical conductivity and magnetic permeability and therefore reacts stronger to the electromagnetic field than the composite, even if the composite is carbon fiber based. I. e. the thermal energy is specifically concentrated in the repair area. In this study, the susceptor was placed on the patch and also in the welding zone. The repair process begins by identifying and preparing the damaged area, followed by precise scarfing. Care is taken to ensure that the surrounding material remains intact and that an exact stepped structure is created, which enables an optimal bonding with the patch to be used. The customized patch, which fits perfectly in terms of shape and material to the area to be augmented, is then inserted into the structure. Induction heating melts the thermoplastic matrix to join the patch with the structure using a flexible induction mat. The repair process is monitored using thermocouples to ensure even heat distribution, while pressure is maintained through a vacuum bag. The vacuum bag ensures a uniform pressure distribution even on complex curved structures. This adaptable repair method can handle individual damages. It was tested on flat carbon fiber-reinforced polyphenylene sulfide (CF-PPS) structures, showing repairs with nearly 70 % of the original performance for copper mesh susceptors. Optical tests of the specimens confirmed a bonding zone with minimal defects. Overall, this method offers a material-compatible solution for TPC repair in future aviation, advancing aerospace maintenance and offering significant potential for future industry use.

MEMS is a more complex technology than traditional semiconductors. They are 3D structures with moving parts, making them much more difficult to fabricate. If you’re designing a semiconductor, you may be able to take advantage of an existing process development kit (PDK), which your foundry can provide to you. There is no equivalent approach in MEMS. It’s a “one process, one product” paradigm that requires a high level of customization. That takes time, money, and resources.
This paper presents Matchit, a novel method for expediting issue investigation and generating actionable insights from textual data. Recognizing the challenges of extracting relevant information from large, unstructured datasets, we propose a domain-adaptable approach by integrating expert domain knowledge to guide Large Language models (LLMs) to automatically identify and categorize key information into distinct topics. This process offers two key functionalities: fully automatic topic extraction based solely on input data, providing a concise overview of the problem and potential solutions, and user-guided extraction, where domain experts can specify the type of information or pre-defined categories to target specific insights. This flexibility allows for both broad exploration and focused analysis of the data. Matchit's efficacy is demonstrated through its application in the automotive industry, where it successfully extracts repair diagnostics from diverse textual sources like repair records, surveys, and customer service logs. By identifying and categorizing information related to failure modes, symptoms, repair actions, and procedures, Matchit enables efficient identification of similar repairs in new datasets, significantly reducing manual review efforts. Case studies presented demonstrate the tool's effectiveness in achieving accurate matching results. Matchit's versatility extends beyond the automotive domain, offering a powerful solution for any application requiring customized information extraction, categorization, and matching from textual data.

In recent years, metal additive manufacturing has emerged as a transformative technology, impacting traditional manufacturing processes across industries. Its ability to create complex geometries and customized parts with unprecedented precision has propelled it to the forefront of innovation in engineering and design. However, when compared to traditional manufacturing techniques, materials produced through 3D printing often exhibit inferior fatigue properties under cyclic loading conditions. This discrepancy significantly limits their widespread application as structural load-bearing components. The challenge lies in addressing the poor fatigue properties commonly attributed to the presence of micro voids induced during the current printing process procedures. Improving the fatigue performance of 3D printed materials and components has thus become a crucial research focus.
The emergence of data-driven healthcare promises predictive and preventive care through enhanced data integration and analytics. This trend means that medical device companies must navigate challenges related to data privacy and operational efficiency while transitioning to a data-centric approach. Artificial intelligence (AI) is spearheading this shift toward hyper-personalized medicine, enabling precision treatments based on genetic profiles and predictive analytics for early disease detection. Advancements in telemedicine, AI, wearable technology, and data analytics, are reshaping how care is delivered, making it more accessible, personalized, and efficient in 2025.
Mechanical component failure often heralds superficial damage indicators such as color alteration due to overheating, texture degradation like rusting or false brinelling, spalling, and crack propagation. Conventional damage assessment relies heavily on visual inspections performed by technicians, a practice bogged down by time constraints and the subjective nature of human error. This research paper delves into the integration of deep learning methodologies to revolutionize surface damage evaluation, addressing significant bottlenecks in diagnostic precision and processing efficiency. We detail the end-to-end process of developing an intelligent inspection system: selecting appropriate deep learning architectures, annotating datasets, implementing data augmentation, optimizing hyperparameters, and deploying the model for widespread user accessibility. Specifically, the paper highlights the customization and assessment of state-of-the-art models, including EfficientNet B7 for multilabel classification and prominent object detection framework such as YOLO. Our results demonstrate the feasibility of automating damage detection, potentially transforming maintenance routines and reliability in mechanical settings. Follow-up research is planned to refine these methodologies, paving the way for a production-ready model that will further enhance the reliability and efficiency of mechanical component maintenance.

This article introduces an advanced state-of-charge (SOC) estimation method customized for 28 V LiFePO4 (LFP) helicopter batteries. The battery usage profile is characterized by four consecutive current pulses, each corresponding to distinct operational phases on the helicopter: instrument check, key-on, recharge, and emergency power output stages. To establish a precise battery model for LFP cells, the parameters of a second-order equivalent-circuit model are identified as a function of C-rate, SOC, and temperature. Furthermore, the observability of the battery model is assessed using extended Lie derivatives. The signal-to-noise ratio (SNR) of the open-circuit voltage (OCV)–SOC relation is analyzed and employed to evaluate the estimator’s resilience against OCV flatness. The extended Kalman filter (EKF) and the unscented Kalman filter (UKF) are utilized for SOC estimation. The results emphasize the significance of meticulously choosing process and sensor noise covariance matrices to achieve a resilient SOC estimator for LFP cells. Furthermore, the UKF demonstrates superior robustness against OCV–SOC relationships compared to the EKF. Lastly, the UKF is selected for testing across various aircraft usage scenarios at 10°C, 25°C, and 45°C. The resultant root mean square errors for SOC estimation at these different temperatures are consistently below 2%, thereby validating the effectiveness of the UKF SOC estimation approach.

North America's first electric, fully integrated custom cab and chassis refuse collection vehicle - slated for initial customer deliveries in mid-2024 - is equipped with a standard advanced driver-assistance system (ADAS). “A typical garbage truck uses commercial off-the-shelf active safety technologies, but the electrified McNeilus Volterra ZSL was purpose-built with active safety technologies to serve our refuse collection customer,” said Brendan Chan, chief engineer for autonomy and active safety at Oshkosh Corporation, McNeilus' parent company. “We wanted to make the safest and best refuse collection truck out there. And by using cloud-based simulation, we could accelerate the development of ADAS and other technologies,” Chan said in an interview with Truck & Off-Highway Engineering during the 2024 dSPACE User Conference in Plymouth, Michigan.

Aerospace is an industry where competition is high and the need to ensure safety and security while managing costs is foremost. Stakeholders, who gain the most by working together, do not necessarily trust each other. Changing backbone technologies that drive enterprise systems and secure historical records does not happen quickly (if at all). At best, businesses adapt incrementally, building customized applications on top of legacy systems. The complexity of these legacy systems leads to duplication of efforts and data storage, making them very inefficient. Technology that augments, rather than replaces, is needed to transform these complex systems into efficient, digital processes. Blockchain technology offers collaborative opportunities for solving some of the data problems that have long challenged the aerospace industry. The industry has been slow to adopt the technology even though experts agree that it has real potential to revolutionize the global supply chain—including maintenance, repair, and overhaul (MRO)—driving tremendous cost, excess inventory, and inefficiencies out of the system. This chapter discusses how the adoption of blockchain technology could have a significant impact on the aerospace industry and addresses some of the unsettled concerns surrounding the implementation of the technology.

Advanced Driver Assistance Systems (ADAS) are becoming common on passenger cars and pickup trucks. Accordingly, the manufacturers and installers of aftermarket equipment for these vehicles have an interest in confirming the functionality of ADAS when their equipment is put in place. However, there is very little publicly available information on the effect of aftermarket components on original equipment ADAS. To address this deficiency, a research program was undertaken in which a 2022 Chevrolet Silverado 1500 light truck was tested in four different hardware configurations, including stock as well as three modified conditions. Aftermarket modifications to the vehicle consisted of increased tire diameters, a level kit, and two different lift kits. A series of physical tests were carried out to evaluate the ADAS performance of the vehicle with modifications. Tests were designed to investigate differences in driver alerts including lane departure warnings, forward collision warnings, blind spot detections, and rear cross traffic alerts. These tests were also developed to assess the variation in vehicle responses when driver assistance technologies intervened. Intervention scenarios examined include lane keeping support, crash imminent braking, and traffic jam assistance. In general, results from the tests did not indicate significant ADAS performance differences when the vehicle was subject to modifications. Nevertheless, some tests showed a greater range in alert distances in certain modified configurations.

For 2D surface temperature monitoring applications, a variant of Electrical Impedance Tomography (EIT) was evaluated computationally in this study. Literature examples of poor sensor performance in the center of the 2D domains away from the side electrodes motivated these efforts which seek to overcome some of the previously noted shortcomings. In particular, the use of ‘sensing skins’ with novel tailored baseline conductivities was examined using the EIDORS package for EIT. It was found that the best approach for detecting a temperature hot spot depends on several factors such as the current injection (stimulation) patterns, the measurement patterns, and the reconstruction algorithms. For well-performing combinations of these factors, customized baseline conductivities were assessed and compared to the baseline uniform conductivity. It was discovered that for some EIT applications, a tailored distribution needs to be smooth and that sudden changes in the conductivity gradients should be avoided to prevent the introduction of artifacts in the reconstructed conductivity field. Still, the benefits in terms of improved EIT performance were small for conditions for which the EIT measurements had been ‘optimized’ for the uniform baseline case. Within the limited scope of this study, only two specific cases showed benefits from customized distributions. For one case, a smooth tailored distribution with increased baseline conductivity in the center provided a better separation of two centrally located hot spots. For another case, a smooth tailored distribution with reduced conductivity in the center provided better estimates of the magnitudes of two hot spots near the center of the sensing skin. Overall, the results at hand suggest that improved 2D surface temperature measurement are best served by continued development of measurements and reconstruction algorithms rather than the use of sensing skins with tailored baseline conductivity distributions.

ABSTRACT A customized approach to Pseudo Random Number Generation (PRNG) is developed specifically for the highly parallelizable sensor models in the ground vehicle autonomy application domain. The work considers three desirable attributes (namely quality, efficiency and determinism). Furthermore, the application demands high fanout (1:1Million+) seeding of traditional PRNGs. An approach using hash functions to generate the seeds for the PRNGs, each of which generates a small (i.e. 20) run of numbers, to handle determinism is investigated. Quality and efficiency are evaluated for multiple combinations of hash functions and PRNGs and a pareto front is created. Quality assessments were performed using industry standard testing suites (TestU01 and PractRand) and efficiency of various hash, PRNG, and batch size combinations was benchmarked on Windows/x64, ARM and NVIDIA/CUDA architectures.

Wearable wireless biosensors are an integral part of digital healthcare and monitoring. Commonly used chipless resonant antenna-based biosensors are simple and affordable but have limited applicability due to their low sensitivity. Now, researchers from Japan have developed a novel, wireless, parity–time symmetry-based bioresonator that can detect minute concentrations of tear glucose and blood lactate. This highly sensitive, tunable, and robust bioresonator has the potential to have a great impact on personalized health monitoring and digitized healthcare systems.

Upper-limb forequarter amputations that involve the removal of the entire arm and scapula require highly customized prosthetic devices that are expensive but yet usually underutilized due to their high maintenance and low comfort levels. At the same time, while cosmetic prostheses — artificial limbs that provide patients the appearance of a pre-amputated body part — have a higher rate of continuous use, they have limitations in functional use.
Made-to-order footwear, clothing, and jewelry. Patient-specific replacement joints and medication tailored to their age and weight. Bespoke bicycles, and office chairs that fit like the proverbial glove. These are just a few examples of the customized or personalized products that consumers have come to demand in recent years. How are manufacturers able to fulfill these expectations? In addition, how can they keep the final price from being driven upward by the immense complexity and supply chain disruption that product customization should cause?
Modeling, prediction, and evaluation of personalized driving behaviors are crucial to emerging advanced driver-assistance systems (ADAS) that require a large amount of customized driving data. However, collecting such type of data from the real world could be very costly and sometimes unrealistic. To address this need, several high-definition game engine-based simulators have been developed. Furthermore, the computational load for cooperative automated driving systems (CADS) with a decent size may be much beyond the capability of a standalone (edge) computer. To address all these concerns, in this study we develop a co-simulation platform integrating Unity, Simulation of Urban MObility (SUMO), and Amazon Web Services (AWS), where Unity provides realistic driving experience and simulates on-board sensors; SUMO models realistic traffic dynamics; and AWS provides serverless cloud computing power and personalized data storage. To evaluate this platform, we select cooperative on-ramp merging in mixed traffic as a study case, and establish human-in-the-loop (HuiL) simulations. The results show that our proposed platform can facilitate data collection and performance assessment for modeling personalized behaviors and interactions in CADS under various traffic scenarios.

The promise of personalized medicine involves a simple device that keeps each person apprised of their level of health, identifies even trace amounts of undesirable biomarkers in blood or saliva, and serves as an early warning system for diseases.
The CORA rating metric is frequently used in the field of injury biomechanics to compare the similarity of response time histories. However, subjectivity exists within the CORA metric in the form of user-customizable parameters that give the metric the flexibility to be used for a variety of applications. How these parameters are customized is not always reported in the literature, and it is unknown how these customizations affect the CORA scores. Therefore, the purpose of this study was to evaluate how variations in the CORA parameters affect the resulting similarity scores. A literature review was conducted to determine how the CORA parameters are commonly customized within the literature. Then, CORA scores for two datasets were calculated using the most common parameter customizations and the default parameters. Differences between the CORA scores using customized and default parameters were statistically significant for all customizations. Furthermore, most customizations produced score increases relative to the default settings. The use of standard deviation corridors and exclusion of the corridor component were found to produce the largest score differences. The observed differences demonstrated the need for researchers to exercise transparency when using customized parameters in CORA analyses.

In order to improve the public service attributes and the utilization efficiency of CAV, the paper proposes a customizable and cruising autonomous bus (CCAB) route planning model. This model makes CCAB as customizable and fast as a taxi, and at the same time as a bus to meet multiple demands. Considering that CCAB needs to meet personalized customized riding demand, the paper combines allocation strategy of customized demands to establish a real-time optimization method for customizable and cruising routes based on the elliptical feasible area. This enable CCAB to have the ability of autonomous cruising and autonomous planning of customized routes. In CAV environment, the driver will be replaced by on-board computer of CCAB, the driver’s empirical route selection method will be replaced by the route planning model proposed in this paper. CCAB use historical ride data from each stop to predict future demand. Based on prediction results, the potential passenger rate of route is calculated, and the route is optimized at the same time, so as to determine the final cruising route of the unloaded/loaded bus. By route optimizing, the load rate of CCAB can be improved and the empty mileage can be reduced. The stability of route planning model proposed in this paper is verified by simulation. Meanwhile, sensitivity analysis is carried out by changing demand density and CCAB number in simulation. The conclusion is drawn that determining the optimal number of CCAB corresponding to different demand densities is of great significance for improving efficiency, reducing empty CCAB driving time and passenger waiting time.

In order to solve the problem that the existing customized bus can only select transfer points on the static line, and cannot dynamically plan the route according to the user's real-time demand, this paper establishes a route planning model of unmanned customized bus with the total cost minimization as the optimization goal. The model comprehensively considers the operating cost, passenger satisfaction and charging demand of driverless public transport to ensure efficient transportation and excellent user experience. Dijkstra algorithm is applied to solve the shortest path selection problem involved in the model, and genetic algorithm is used to solve the model. The route selection schemes of vehicle transportation plan, driving route and charging plan are obtained to achieve the goal of minimizing the total cost. The validity and practicability of the model and method are verified by the example of Sioux Falls network.
