Effective operation and performance improvement methods for OMTP BONDI-based mobile Web widget resources

Journal of Zhejiang University-Science C(Computers and Electronics) 2011年第10期12卷 787-799页

作者： jiwoong bang Daewon KIM Department of Computer Science Dankook University Department of Multimedia Engineering Dankook University

The Open Mobile Terminal Platform (OMTP) is a global forum made by telecommunications providers to promote user-oriented mobile services and data businesses. Devised by OMTP, BONDI is a browser-based application or a mobile Web run-time platform to help widgets make good use of the functions of mobile devices in a secure way. BONDI enables applications programmed with Web standard technologies such as HTML, JavaScript, CSS, and AJAX to reach the internal functions of mobile devices. Since BONDI, which is not just a simple network application, can reach the internal resources of devices in standard ways, it enables the application and widgets to be developed regardless of the operating system (OS) or platform. Web browser-based widgets are vulnerable to the network environment, and their execution speed can be slowed as the operations of the widgets or applications become heavy. Compared with the native widgets inside the device, however, those Web widgets will be continuously used thanks to the user-friendly simple interface and the faster speed in using Web resources. This study deals with a method to effectively operate and manage the resources of OMTP BONDI Web widget and provides improved results based on running performance evaluation experiments. The experiments were carried out to improve the entire operating time by enhancing the module-loading speed. In this regard, only indispensable modules were allowed to be loaded while the BONDI widget was underway. For this purpose, the widget resource list, which can make the operating speed of the BONDI widget faster, was redefined while a widget cache was employed. In addition, the widget box, a management tool for removed widgets, was devised to store temporarily idle widgets.

ACSF-ED: Adaptive Cross-Scale Fusion Encoder-Decoder for Spatio-Temporal Action Detection

引用

Computers, Materials & Continua 2025年第2期82卷 2389-2414页

作者： Wenju Wang Zehua Gu bang Tang Sen Wang Jianfei Hao College of Publishing University of Shanghai for Science and TechnologyShanghai200093China Institute of Information Technology Shanghai Baosight Software Co.Ltd.Shanghai200940China

Current spatio-temporal action detection methods lack sufficient capabilities in extracting and comprehending spatio-temporal information. This paper introduces an end-to-end Adaptive Cross-Scale Fusion Encoder-Decoder (ACSF-ED) network to predict the action and locate the object efficiently. In the Adaptive Cross-Scale Fusion Spatio-Temporal Encoder (ACSF ST-Encoder), the Asymptotic Cross-scale Feature-fusion Module (ACCFM) is designed to address the issue of information degradation caused by the propagation of high-level semantic information, thereby extracting high-quality multi-scale features to provide superior features for subsequent spatio-temporal information modeling. Within the Shared-Head Decoder structure, a shared classification and regression detection head is constructed. A multi-constraint loss function composed of one-to-one, one-to-many, and contrastive denoising losses is designed to address the problem of insufficient constraint force in predicting results with traditional methods. This loss function enhances the accuracy of model classification predictions and improves the proximity of regression position predictions to ground truth objects. The proposed method model is evaluated on the popular dataset UCF101-24 and JHMDB-21. Experimental results demonstrate that the proposed method achieves an accuracy of 81.52% on the Frame-mAP metric, surpassing current existing methods.

Lamb wave TDTE super-resolution imaging assisted by deep learning

Chinese Physics B 2025年第1期34卷 357-366页

作者： Liu-Jia Sun Qing-bang Han and Qi-Lin Jin College of Information Science and Engineering Hohai UniversityChangzhou 213200China

Ultrasonic Lamb waves undergo complex mode conversion and diffraction at non-penetrating defects, such as plate corrosion and cracks. Lamb wave imaging has a resolution limit due to the guided wave dispersion characteristics and Rayleigh criterion limitations. In this paper, a full convolutional network is designed to segment and reconstruct the received signals, enabling the automatic identification of target modalities. This approach eliminates clutter and mode conversion interference when calculating direct and accompanying acoustic fields in time-domain topological energy(TDTE) ***, the measured accompanying acoustic field is reversed for adaptive focusing on defects and enhance the imaging quality. To circumvent the limitations of the Rayleigh criterion, the direct acoustic field and the accompanying acoustic field were fused to characterize the pixel distribution in the imaging region, achieving Lamb wave super-resolution imaging. Experimental results indicate that compared to the sign coherence factor-total focusing method(SCF-TFM),the proposed method achieves a 31.41% improvement in lateral resolution and a 29.53% increase in signal-to-noise ratio for single-blind-hole defects. In the case of multiple-blind-hole defects with spacings greater than the Rayleigh criterion resolution limit, it exhibits a 27.23% enhancement in signal-to-noise ratio. On the contrary, when the defect spacings are relatively smaller than the limit, this method has a higher resolution limit than SCF-TFM in super-resolution imaging.

Cd Enrichment Characteristics and Bioavailability of Soil-crops in the Migration Type Geological High Background Area of Poyang Lake，Jiangxi Province

引用

Huanjing Kexue/Environmental Science 2025年第3期46卷 1774-1782页

作者： Wen, bang-Yong Qie, Hai-Man Gao, Yuan Jiang, Hong-Yu Zhou, Qiang-Qiang Basic Geological Survey Institute of Jiangxi Geological Survey and Exploration Institute Nanchang330030 China Key Laboratory of Mine Environmental Monitoring and Improving Around Poyang Lake Ministry of Natural Resources East China University of Technology Nanchang330013 China Jiangxi Nonferrous Geological Mineral Exploration and Development Institute Nanchang330030 China

To study the accumulation characteristics and bioavailability of Cd in the soil-crop system in the migration type geologically high background area，140 groups of crops and soil samples were collected from the Jiulong area on the south bank of Poyang Lake. The results showed that the range of ω （Cd） of root soil was 0.03-0.65 mg·kg-1，with an average of 0.16 mg·kg-1，which exceeded the background value of soil in Jiangxi Province，reflecting the characteristics of high geological background of migration type. The over-standard rate of Cd in root soil was 6.43%，which was slightly polluted. Sesame had the strongest enrichment ability of Cd （404%），followed by that of peanut （146%）. The enrichment ability of rice，Camellia oleifera，and Euryale seed was medium，while that of corn was weak. The root soil ω （active Cd） was 76.8 μg·kg-1，and the bioavailability was 48.9%，among which rice was the highest with 98.6 μg·kg-1 and 59.9%，respectively. Principal component analysis （PCA） showed that root soil Cd was mainly caused by the transport and accumulation of industrial and mineral pollutants in the upstream，reflecting the characteristics of the high geological background of the transport type. Correlation showed that the active and bioavailable Cd of root soil were mainly controlled by genetic sources，indicating that the activity of exogenously imported Cd was higher，and the ecological risk was higher. © 2025 Science Press.

标准必要专利(SEP)同时具备专利的垄断性与标准的开放性特征,但各国专利机关受传统职能范围限制,仅将其视为一般专利进行管理而无针对性治理措施,无法解决SEP治理中的一系列难题。既有的标准制定组织治理、法院治理、反垄断执法机关治理等模式因其各自局限性难以满足SEP治理需求,导致实务冲突频发,从而引发专利机关应如何治理SEP的探索。专利机关治理SEP有其独特优势,通过拓展其职能以满足SEP治理需求不仅能够弥补既有治理模式的不足,还能很好地回应目前SEP全球治理的新要求与新趋势,有利于全面提升我国SEP治理水平。作为政府管理机关的组成部分,专利机关所应具有的专利管理职能、公共利益保护职能、纠正市场失灵职能等为专利机关拓展SEP治理职能提供了正当性与合理性;专利法的价值、功能及其内容拓展为专利机关拓展SEP治理职能提供了法律基础。构建包括专利机关SEP治理理念、治理原则、治理制度总体框架和治理制度具体微观规则在内的四位一体治理制度体系,是实现专利机关对SEP治理的重要路径。
