Railway master data is crucial for ensuring consistency and accuracy across information systems. As railway informatization progresses, the types and volumes of data have rapidly increased, making traditional master data management methods increasingly inadequate. On the other hand, the railway industry has high demands for data processing speed and security. Therefore, effectively managing high-value data that is reused across different business domains is key to improving the efficiency and safety of railway systems. This study proposes a new master data management technology by combining advanced artificial intelligence (AI) and blockchain technology to address the pain points in railway master data management. Experiments show that applying this framework can intelligently identify and classify complex business data, effectively supporting dynamic updates and intelligent governance of master data. © Beijing Paike Culture Commu.

The façade is an essential component of commercial and public buildings and plays a fundamental role in their energy efficiency and on their carbon footprint. This research aimed to investigate the most recent trends in advanced façade designs that apply metal components to achieve high environmental performances and minimise environmental impacts. Goal of the research was to better understand current and future design strategies of metal facades for high-performance buildings. More than 100 precedents, built between 2015 and 2023, were examined to better understand the recent application of these materials and products in advanced façade designs. Parameters such as type of façade components, alloys, finishing, surface albedo, context etc., were taken into consideration. A literature review on environmental impacts of new metal facades and claddings was carried out to inform and validate the results of the survey on precedents. Results showed a higher incidence of aluminium over other materials. Claddings tend to be more lightweight, de-materialised, stratified and more permeable, also to reduce embodied carbon and improve acoustic performances. Solar shading is becoming a prevalent application and new smart materials offer zero-energy systems. Light albedo surfaces are preferred to reduce the urban heat island effect generated by these materials. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Power systems are exposed to risks from various external events such as disasters and attacks. Hardening power lines prior to extreme events can effectively mitigate their impact on the system. For spatial power systems and events, a line hardening resource allocation model based on a tri-level optimization framework involving defender, event (or attacker), and operator roles for localized failures (or attacks) is proposed. The model accounts for defense costs associated with line length and calculates the failure probabilities of lines based on their distances from the failure center, employing Shannon’s information entropy theory to quantify this uncertainty. The tri-level model is transformed and solved using the Column-and-Constraint Generation (C&CG) method, thereby determining the optimal line hardening resource allocation strategy and identifying the corresponding worst-case scenario. The effectiveness of the proposed model is validated using the IEEE-24 bus system, and the results are analyzed. This model provides insights into enhancing the resilience of power systems against spatial extreme events. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In a survey, a lot of questions and answers are listed and participators will select one of the answers for each question. Sometimes, participators may not be willing to select the preferred one item in the answers because the item may damage the privacy of themselves. If this question is not answered, then it reveals that the question or the answers are sensitive, which also damages the privacy. Besides, each participator may have distinct privacy concerns even for the same questions and answers, thus the privacy-aware questions and answers cannot be determined and be removed in advance. Thus, the dilemma is how to select the answers for privacy-aware questions yet maintain the utility of the answering results in the survey. In this paper, we propose a general method to protect the various privacy in the investigation without the knowledge of privacy to be protected in advance. The main idea is that participators can randomly select answers if the privacy is the concern for themselves in the answers for this question. Our method is lightweight so as to be convenient in practices. We extensively analyze the accuracy of survey results to justify that our method can protect the privacy yet maintain the utility of the investigation. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

For the security of its water and electricity, India has a vast network of dams. However, as many of these dams were constructed many years ago, they now need to be renovated due to aging. This poses a substantial engineering problem because the restoration work must not only guarantee the dam's structural integrity but also incorporate environmentally friendly procedures for long-term operation. Electrical engineering has a key role to play in India's sustainable rehabilitation of deteriorating dams. By utilizing contemporary turbine-generator technology, many dams can increase their ability to generate electricity. By producing more electricity with the same amount of water, new turbines can improve a dam's efficiency and lessen its environmental impact. The monitoring and control system of the dam needs to be improved as part of sustainable rehabilitation. Modern sensing technologies enable operators to optimize dam operations for optimal efficiency and safety by providing real-time monitoring of water levels, temperature, and other characteristics. Last but not least, electrical engineers can help create a smart grid system that uses renewable energy sources like solar and wind power. This can improve the overall sustainability of the dam and help India meet its growing demand for electricity while reducing its dependence on fossil fuels. A sustainable rehabilitation approach to India's aging dams must encompass a range of electrical engineering solutions to ensure their long-term viability. Upgrading the dam's turbines, implementing advanced monitoring and control systems, and developing a smart grid system can all contribute to achieving this goal. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

To improve the overall safety and comfort level of highway alignment geometric design scheme, driving simulation experiment is designed and implemented. Firstly, a subjective quantitative evaluation analysis is performed on the amenity, consistency, and comfort of the alignment design. The aggregation area and distribution state of driving speed are analyzed. The consistency of the operating speed consistency of each alignment unit is analyzed on the basis of the unit division of horizontal (H) and vertical (V) alignment. Considering the sensitivity of x-lateral acceleration (Ax) outliers in the driving process, the variation degree of Ax data for each alignment unit is analyzed based on the robust coefficient of variation (RCV), and the units with poor comfort of alignment geometric design are identified. The key range and sequence of optimization adjustment of alignment geometric design elements of alignment are presented by the comprehensive analysis of the combined unit of horizontal and vertical (HV) curves. The results showed that the subjects had higher scores on the amenity and consistency of the alignment design, but the driving comfort was relatively poor affected by the terrain;H2 speed fluctuation is more complex than H1, H1, V2, V3, and V4 units have poor speed coordination sections. Compared with coefficient of variation (CV), RCV is better at characterizing dispersion and stability of Ax data. Adjusting the design index within the alignment unit H2, V3, V4, V5 is the key to improving the overall driving comfort of the route. The RCV of the HV unit is smaller than that of the independent alignment unit. When optimizing the comfort of the design scheme, it is necessary to focus on adjusting the radius and slope of the HV1 unit, considering the combination design of the HV2 and HV3 units, and avoiding the unfavorable combination form containing multiple vertical curves in H2. © 2025 SPIE.

With Artificial Intelligence applications becoming ubiquitous, both industrial and consumer applications require more computing availability. The increasing need for power-constrained Artificial Intelligence computing asks for new and innovative solutions, on both hardware design as well as on software toolchains that leverage them. At the same time, the challenge of EU technological sovereignty encourages an industry trend oriented to developing its own solutions for power efficient High Performance computing (HPC). In this context, as partners in the ISOLDE project started in 2023, we propose the development of new power efficient embedded HPC accelerators, HPC design platforms, as well as High Level Synthesis (HLS) approaches and toolchain technology designs for RISC-V based applications. Specifically, we envisage applications such as Fast Fourier Transform, Number Theoretic Transforms, Post Quantum computing and artificial intelligence, as well as designing ONNX targeted toolchains based on the LLVM compiler, open solutions for Neural Networks (NN) accelerators and new OpenMP extensions. Within the ISOLDE framework, the envisaged applications to prove the readiness of these technologies are the Automotive and the smart Home demonstrators.

Sentiment analysis is gaining prominence in the evaluation of patient satisfaction within healthcare environments. The present article takes advantage of VADER-IT, an Italian language adaptation of the VADER sentiment analysis engine, to analyze patient reviews of hematological care facilities. In particular, 526 reviews published on the QSalute review platform (https://***/ ), by patients who had received care in hospitals and medical facilities across Italy. Sentiment polarity was extracted from each Italian review using VADER-IT. To assess performance, the user’s averaged rating was dichotomized and considered as ground truth. VADER-IT was further compared to the English version of VADER applied to reviews translated into English. The results reveal the superior performance of our method on Italian data compared to VADER applied to translated content. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
