Supporting free VCR-like operations in P2P VoD streaming systems is challenging. The uncertainty of frequent VCR operations makes it difficult to provide high quality realtime streaming services over distributed self-organized P2P overlay networks. Recently, prefetching has emerged as a promising approach to smooth the streaming quality. However, how to efficiently and effectively prefetch suitable...
Aim at developing the multi-functional products, the using process can be divided into different scenarios by the function, then we organize different stakeholders by scenario to participate in the process of the requirement elicitation. We propose a collaborative requirement elicitation approach based on scenario, and validate the integrity and consistency of the requirement. At last, we present...
The efficiency and quality of product agile design (PAD) is essentially about designer as well as in a rapidly changing and strongly competitive environment. The primary objective of this fundamental research will be to propose the conception of product agile design management (PADM), which designed specially for design affairs management of product agile design. The author carried on deep research...
Callus culture of Elaeagnus angustifolia was established with the objective to produce proanthocyanidins. The effects of different conditions on the callus growth and the production of proanthocyanidins were researched. The leaf tissue part of Elaeagnus angustifolia was optimum explant of callus induction. The best callus growth and the highest proanthocyanidins production was obtained under the culture...
In this work, we described a new two-stage hierarchical framework for mammogram retrieval. We tested the proposed approach on the reference library from USF-DDSM. For each query ROI (region of interest), the proposed scheme first computes its 14 texture and shape features, then the voting method based on five classifiers is used to classify the ROIs in the reference library, this phase eliminates...
In this paper, we took Elaeagnus angustifolia as material. The paper studied characteristics of seasonal and spatial variations of proanthocyanidins content. There was an apparent difference in proanthocyanidins content of the leave from May to October, the maximim content of proanthocyanidins in October was 34.36 mgldrg-1 DW, while proanthocyanidins content in July was only 17.16 mgldrg-1 DW. Content...
Many studies have been proposed to identify gene makers that are associated with cancers, but the found markers are approach dependent. For example, the results are correlated with classifiers in supervised feature selection, and many of them didn't consider the influences of other factors, such as the grades or stages of cancers. In this study, we proposed a supervised SVD approach to extract the...
Latent semantic indexing (LSI), as a popular textual information retrieval approach, has been used heavily for many years. However, the use of the approach in image retrieval has been limited. In this paper, a method of using LSI in combination with the salient image representation based on a saliency-based bottom-up visual attention computational model (VACM) motivated by visual physiological experimental...
Because that data analysis methods for train ticket data are mostly designed for building predictive analysis models, which are always good at describing the characteristics of major classes but are lack of reflecting the minorities, this paper presents a new method FEBIR that is based on the set-partition for data feature extraction. The presented method can distill the pointed favorite class features...
