Most existing multimodal named entity recognition (MNEr) methods cannot align image and text well, and fail to effectively fuse image-text semantic information, leading to suboptimal MNEr accuracy. To this end, this paper proposes a novel named entity recognition model based on Contrastive Learning and Multimodal Semantic Interaction (named CLMSI). Specifically, to narrow the semantic gap between image-text modalities, making semantically similar image-text representations closer and pushing dissimilar ones further apart, we propose a contrastive learning-based cross-modal alignment method. Moreover, to integrate multimodal information effectively and filter out the noise introduced by image features as thoroughly as possible, we propose to incorporate image descriptions as additional features to enrich the multimodal representation and to reduce the semantic bias of the image information. Extensive experiments conducted on two MNEr benchmark datasets, Twitter-2015 and Twitter-2017, demonstrate the superiority of the proposed method. Further ablation studies and case analyses also affirm the efficacy of CLMSI. © 2024 IEEE.

Precision Education (PE) is an approach that emphasizes the use of various forms of technology to personalize students’ educational opportunities according to their unique requirements. In order to facilitate effective learning that is suited to the needs of each individual, it is necessary to have complete information about the learning process. PE describes a personalized approach to classroom instruction. We propose dignified reinforcement Learning (drL) which includes all the essential elements required for PE, in order to determine the impact of developing multimodal innovations on individualized learning. The system aims to address issues with the standard model of education analysis, such as insufficient internal validity, predictive validity, timeliness, comparability, and understandability, in order to provide more precise instruction. Networking sites, the digital classroom, the intelligent agent, and the panel are the four fundamental aspects of an rL-based technology. Through model-based rL, the head attribute of the continuous educational environment gathers and processes a multimodal flow of student records from the various modules to create laws of appropriate behaviors that optimize the long-term benefits for both the individual and the computer. To demonstrate the usefulness of the proposed model, experimental evidence was presented using a subset of multimodal data. Practical and theoretical implications for future digital learning approaches and investigations may be drawn from rL systems. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Composite materials are defined as new materials formed by combining two or more materials that do not mix, leveraging the best properties of each constituent. Composite materials are used in important industrial sectors such as aerospace and automotive due to their superior properties. In this study, XPS (extruded polystyrene) polymer foam was utilized as the core material. Glass fibers were combined with resin in a total of eight and twelve layers and applied to both the top and bottom of the core structure. Production involved both manual laying and vacuum bagging methods. Two types of glass fiber, weighing 200 g/m2 and 300 g/m2, were employed. After production, the composites were cut to standardized dimensions, followed by three-point bending and low-speed impact tests. Impact experiments were conducted with a constant energy of 50 J. results showed that the 200 g/m2 glass fiber composites experienced perforation in the eight-layer samples and rebound in the twelve-layer samples. Although greater deformation was observed in the impact tests of the 300 g/m2 glass fiber composites in the eight-layer samples compared to the twelve-layer samples, a rebound occurred in both. In three-point bending tests, the bending strength increased as the number of layers increased, and at the same number of layers, composites with 300 g/m2 properties showed higher strength than 200 g/m2 composites. © 2025 The Author(s).

2023 9th International Conference on Applied Materials and Manufacturing technology, ICAMMT 2023

作者： Xu, Ziye Xu, Hongmei Song, Qi Zhang, Zhe Wen, Zhidong Li, Man Hou, Yu School of Electronic Information Engineering Changchun University of Science and Technology Jilin Province Changchun City China Institute of Microelectronics Chinese Academy of Sciences Microelectronics Instruments and Equipment R&D Center Beijing China

As an advanced wafer dicing technology, stealth dicing has the advantage of better-cutting quality and faster-cutting speed than traditional blade dicing technology and has a broad application prospect for the future cutting of large and ultra-thin silicon wafers. The stealth dicing equipment involves two processes, i.e., wafer altimetry and follow-through processing in silicon wafer cutting, the altimetry accuracy of which determines the processing precision. In this paper, polynomial fitting, linear interpolation, and cubic spline interpolation are applied to predict the altimetry data at different speeds to achieve high-speed and high-precision altimetry under various speed conditions. The research shows that the prediction accuracy of the three methods is less than 1 μm. The linear interpolation has the highest accuracy during the altimetry speeds of 500 mm/s ∼ 1500 mm/s. The polynomial fitting can achieve better prediction results by selecting the best fitting parameter when the altimetry speeds are 1500 mm/s ∼ 2500 mm/s. The cubic spline interpolation is more suitable for the processing of data sampled at altimetry speeds between 2500 mm/s and 3000 mm/s. © Published under licence by IOP Publishing Ltd.
