However, existing agricultural pest datasets have limitations in terms of species diversity and the number of samples, and only the appearance of the pest is considered while ignoring professional agricultural knowledge. In this paper, a large-scale dataset, termed AP162, is proposed for the recognition of agricultural pests, which consists of 162 pest categories and 194,700 images. AP162 takes into account both the visual appearance of agricultural pests and their harmful characteristics for crops. Different subset divisions are adopted to explore the appearance features and potential damage to pests from two perspectives. The agriculture-based perspective classifies pests according to crop damage types to support targeted pest control, while the vision-based perspective relies on morphological similarities. Extensive experiments have been conducted on the AP162 dataset utilizing recent deep learning methodologies, thereby establishing it as a new benchmark. This paper proposes a weighted fusion strategy that agricultural domain knowledge is integrated with vision-based fine-grained feature, achieving a recognition accuracy of 89.2% on AP162.

Specifically, the study examines the perspectives, reflections, and learning processes of CFL learners enrolled in a 16-week SCVL program. The research utilizes a qualitative design with inductive thematic analysis to analyze data collected from semi-structured interviews and reflective journals. The study involved a cohort of 32 intermediate-level students from three Chinese classes, with participants representing diverse Chinese proficiency levels. A purposive sampling method was used to select students who had actively engaged in the SCVL program. Thematic analysis of the data revealed two key themes: (1) affective engagement, which highlights students' emotional involvement and motivation in the seamless learning environment, and (2) issues and challenges, which focuses on the difficulties students encountered, such as technological barriers and frustration with peer reviews. Despite these challenges, the findings indicate that most students found the SCVL approach enjoyable and beneficial in enhancing their vocabulary learning, with many expressing positive views about the integration of mobile-assisted learning tools. This study contributes to the growing body of research on seamless learning by providing in-depth insights into the experiences of tertiary-level CFL learners. It offers novel contributions to the field by addressing the gaps in previous studies that have not fully captured students' perspectives and challenges in using mobile-assisted seamless learning for vocabulary acquisition.

This study aims to investigate by using CFD modelling a hydrogen fuelled marine dual-fuel engine to identify operating settings ranges for different hydrogen energy fractions (HEF), as well as parametrically optimise the diesel fuel injection timing and temperature at inlet valve closing (IVC). A large marine four-stroke engine with nominal power of 10.5 MW at 500 rev/m is considered, assuming operation at 90 % load and hydrogen injection in the cylinders intake ports. CFD models are developed for several operating scenarios in both diesel and dual-fuel modes. The models are validated against measured data for the engine diesel mode and literature data for a hydrogen-fuelled light-duty engine. A convergence study is conducted to select the grid compromising between computational effort and accuracy. Parametric runs for 20 %, 40 % and 60 % HEF with different IVC temperature and diesel start of injection are modelled to quantify the engine performance, emissions, and combustion characteristics. A single parameter optimisation is conducted to determine the most effective pilot diesel injection timings. The results reveal the IVC temperature range for stable hydrogen combustion to avoid incomplete combustion at low IVC temperature and knocking above 360 K. The proposed settings lead to higher peak heat release rate and in-cylinder pressure compared to the diesel mode without exceeding the permissible in-cylinder pressure rise limits for 60 % HEF. However, NOx emissions increase to 12.9 g/kWh in the dual-fuel mode. The optimal start of injection (SOI) for the diesel fuel, in the case of 60 % HEF, is found 8 °CA BTDC resulting in an indicated thermal efficiency of 43.2 % and stable combustion. Advancing SOI beyond the optimal value results in incomplete combustion. This is the first study on hydrogen use in large marine four-stroke engines providing insights for the engine design and operation, and as such it contributes to the maritime industry decarbonisation efforts.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"144 ","pages":"Pages 239-251"},"PeriodicalIF":8.1,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
