In ancient times, different kinds of glass products appeared due to different combustion promoters added to the glass during the melting process. Glass is easy to be weathered during burial, resulting in changes in chemical composition. Therefore, it is difficult to analyze its composition and determine its type. Firstly, Pearson correlation coefficients were used to analyze and the correlation coefficients of surface weathering with type, color and decoration were obtained as:0.34, -0.22 and 0.05, respectively. Then the patterns of chemical composition contents were counted for different types of glass in different states, and it was obtained that barium glass showed a decreasing and increasing trend after weathering, respectively. Then a decision tree was used to predict the chemical composition content of the glass before weathering. Then, the binary statistical analysis was used to determine that when the total content of Na2 O, K2 O and CaO was greater than the total content of PbO and BaO, the glass type was Highpotassium glass, and the opposite was lead-barium. Then K-Means clustering analysis was used to obtain the subclassification of both High-potassium glass and lead-barium glass as three types. Then, using BP neural network, with all chemical components as input layer and glass type as output layer, we obtained Al, A6, A7 as High-potassium glass and A2, A3, A4, A5 as lead-barium. Finally, using Pearson correlation coefficients, the comparison found that the individual chemicals in High-potassium glass were more correlated. © 2023 IEEE.

This article proposes a tea harvesting robot path planning method based on an improved ant colony algorithm. Firstly, it analyzes the characteristics of tea harvesting robot path planning, and introduces the basic principles and model of the ant colony algorithm. Then, in order to address the issue of the ant colony algorithm easily getting stuck in local optima, it combines the principles of genetic algorithms to incorporate operations such as swapping, insertion, and reversal into the ant colony algorithm. Experimental results demonstrate that the improved ant colony algorithm exhibits better path planning efficiency and convergence speed as the number of tea leaf buds increases. Compared to the classical ant colony algorithm, it effectively avoids the problem of getting trapped in local optima. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

3DSN-Net: A 3-D Scale-Aware convNet With Nonlocal Context Guidance for Kidney and Tumor Segmentation From CT Volumes

Automatic kidney and tumor segmentation from CT volumes is a critical prerequisite/tool for diagnosis and surgical treatment (such as partial nephrectomy). However, it remains a particularly challenging issue as kidneys and tumors often exhibit large-scale variations, irregular shapes, and blurring boundaries. We propose a novel 3-D network to comprehensively tackle these problems;we call it 3DSN-Net. Compared with existing solutions, it has two compelling characteristics. First, with a new scale-aware feature extraction (SAFE) module, the proposed 3DSN-Net is capable of adaptively selecting appropriate receptive fields according to the sizes of targets instead of indiscriminately enlarging them, which is particularly essential for improving the segmentation accuracy of the tumor with large scale variation. Second, we propose a novel yet efficient nonlocal context guidance (NCG) mechanism to capture global dependencies to tackle irregular shapes and blurring boundaries of kidneys and tumors. Instead of directly harnessing a 3-D NCG mechanism, which makes the number of parameters exponentially increase and hence the network difficult to be trained under limited training data, we develop a 2.5D NCG mechanism based on projections of feature cubes, which achieves a tradeoff between segmentation accuracy and network complexity. We extensively evaluate the proposed 3DSN-Net on the famous KiTS dataset with many challenging kidney and tumor cases. Experimental results demonstrate our solution consistently outperforms state-of-the-art 3-D networks after being equipped with scale aware and NCG mechanisms, particularly for tumor segmentation. © 2013 IEEE.

The paper provides a method with relatively high computational efficiency and accuracy to solve the linear equation systems (LES). That is, the paper presents a simplified 94LVI algorithm solution to a linear equation system, based on the original 94LVI algorithm solution to a quadratic program (QP) problem. The linear equation system can be shown as a result of a simplified quadratic program. The simplified 94LVI algorithm is thus developed to solve the simplified quadratic program problem, i.e., the linear equation system. The simplification method provided is practical to this kind of LES problems, and effectively solves the LES problems. Besides, numerical experiments of different dimension examples are carried out to verify the effectiveness and efficiency of the presented method. © 2024 IEEE.

The release of ChatGPT heralds a new era in artificial intelligence, as large language models (LLMs) empower myriad industries. This paper introduces RSChat, a model based on supervised fine-tuning of multiple large language models (LLMs), exploring a novel paradigm for applying knowledge in railway safety. Initially, we perform prompt engineering using collected domain data, including key information extraction and knowledge expansion. Subsequently, leveraging the constructed fine-tuning datasets, we conduct supervised fine-tuning using multiple large language models (LLMs) as base models. Finally, experimental evaluations demonstrate that RSChat can generate more professional responses in the railway safety domain, exhibiting robust potential for application. © 2024 IEEE.

In environments where natural disasters such as earthquakes, fires, and typhoons occur frequently, rescue workers are unable to understand the specific situation and carry out rescue operations in a timely manner due to the complex terrain. Multilegged robots can adapt well to these environments and carry out rescue work in complex environments. We design a multiterrain rescue robot system based on STM32. The system achieves remote control of the walking of the proposed hexapod robot through a mobile app, and collects indicators such as the concentrations of smoke and toxic gas, which can adapt to walking in various complex terrains. We use STM32 as a core component to design a gain control module for controlling the walking of the proposed rescue robot. In addition, we use various sensors to collect environmental indicators and detect personnel information. Experiments demonstrate that the rescue robot can adapt well to walking in various terrains. It is helpful for promoting the development of rescue robot systems. © 2024 SPIE.

This paper discusses the use of a method for collecting a high dynamic range image from intermediate images with contrast enhancement in different parts of the amplitude characteristic. Simultaneously, for each subrange, the chromaticity coordinates of a colour space with a large coverage are recalculated. In the new color space, the dots shift slightly, but the nature of the shift depends on the color tone. © 2024 IEEE.
