Implementation of a weblog extraction system with an improved template extraction technique

Chinese Journal of Library and Information Science 2013年第1期6卷 52-63页

作者： e CHANG Southeast University Library The Institution of Information Science and Technology Southeast University

Purpose: The objectives of this study are to explore an effective technique to extract information from weblogs and develop an experimental system to extract structured information as much as possible with this technique. The system will lay a foundation for evaluation, analysis, retrieval, and utilization of the extracted ***/methodology/approach: An improved template extraction technique was *** templates designed for extracting blog entry titles, posts and their comments were established, and structured information was extracted online step by step. A dozen of data items, such as the entry titles, posts and their commenters and comments, the numbers of views, and the numbers of citations were extracted from eight major Chinese blog websites,including Sina, Sohu and ***: Results showed that the average accuracy of the experimental extraction system reached 94.6%. Because the online and multi-threading extraction technique was adopted, the speed of extraction was improved with the average speed of 15 pages per second without considering the network delay. In addition, entries posted by Ajax technology can be extracted *** limitations: As the templates need to be established in advance, this extraction technique can be effectively applied to a limited range of blog websites. In addition, the stability of the extraction templates was affected by the source code of the blog *** implications: This paper has studied and established a blog page extraction system,which can be used to extract structured data, preserve and update the data, and facilitate the collection, study and utilization of the blog resources, especially academic blog ***/value: This modified template extraction technique outperforms the Web page downloaders and the specialized blog page downloaders with structured and comprehensive data extraction.

慢性阻塞性肺疾病居全球死因的第四位[1],居美国致残病因的第二位,因此,临床上需建立一套更简便可靠的方法评估患者的预后.目前对于支气管扩张、肺囊性纤维化和伴不可逆气流阻塞的慢性哮喘是否应归入慢性阻塞性肺疾病(COPD)仍存在争议,两项指南根据已有的临床证据将[2,3] COPD的范畴定义为慢性阻塞性支气管炎、肺气肿或两者兼有.以往认为COPD是一种不可逆的病变过程,干预措施少,预后差,缺乏有效的诊治方法。

The relationships between the global general circulation and the Indian monsoon during active and break phases are investigated with the help of FGGe IIIb *** was found that the ultralong wave component positive and negative height anomalies over Tibet are associated with active and break monsoon phases respectively. This ultralong wave component has significant effect even upto 22°N over the Indian region which is the monsoon trough region. During a monsoon break, the general circulation was found to be more turbulent in the sense that more waves become *** was observed that during a break, blocking prevails over the Siberian region and cold air advection takes place toward Indian region from Siberian region depressing the temperatures over the Indian region by about 1℃. During the break, the Indian region gets connected with higher latitudes by the south winds blowing from polar Soviet regions to the Indian region. From active to break phase the zonal component weakens by about 25% from Indian ocean area right upto Alaskan region, along the east coast of Asia.

Deposition behavior and tribological properties of diamond-like carbon coatings on stainless steels via chemical vapor deposition

引用

International Journal of Minerals,Metallurgy and Materials 2018年第11期25卷 1335-1343页

作者： Labani Mustafi M.M.Rahman Mohammad Nur e Alam Al Nasim Mohammad Asaduzzaman Chowdhury M.H.Monir School of Materials Science and engineering Harbin Institute of TechnologyHarbin 150001China School of engineering RMIT UniversityMelbourneVictoria 3001Australia Dhaka University of engineering and Technology Gazipur 1707Bangladesh

A systematic investigation was carried out to observe the deposition rate of a diamond-like carbon(DLC) coating on two stainless steel substrates by chemical vapor deposition(CVD). The objective of this research is to study the deposition behavior of the DLC coating and its tribological properties in different combinations of methane(CH_4) and nitrogen, which were used as precursor gases. The results reveal that the deposition rate increases with increasing CH_4 content up to 50 vol%. The hardness of the DLC-deposited layer also increases while the friction coefficient decreases with increasing CH_4 gas content up to 50% in the precursor gas mixture.

Global standard names for the Lowermost Cambrian Series and Stage

The GSSP marking the base of the Cambrian System was ratified by the lUGS in 1992. Ratification of the GSSP point at the base of the Trichophycus pedum Ichnozone in the Fortune Head section, eastern Newfoundland, Canada, automatically defined the conterminant base of the lowermost series and stage of the Cambrian although names for those subdivisions were not proposed at the time of the decision. In 2007, the lUGS ratified the names Terreneuvian Series and Fortunian Stage for these previously unnamed chronostratigraphic subdivisions. The Terreneuvian Series replaces the provisional name ＂Series 1,＂ and the Fortunian Stage replaces the provisional name ＂Stage 1,＂ of the Cambrian System.

A Limited Area Model for Monsoon Prediction

引用

Advances in Atmospheric Sciences 1990年第1期7卷 111-126页

作者： S.S.Singh S.S Vaidya e.N.Rajagopal Indian Instituteof Tropical Meteorology Pune-411005 IndiaIndian Instituteof Tropical Meteorology Pune-411005 IndiaIndian Instituteof Tropical Meteorology Pune-411005 India

A six level regional primitive equation model has been formulated and tested for monsoon prediction. The model uses dynamic normal mode initialization scheme for obtaining initial balance. The physical processes included are: the large scale condensation, the Kuo type of cumulus convection, the surface friction, the sensible heat supply and evaporation over the sea. The actual smooth orography is included. The model has been integrated for 48 hrs using input of 7 July and 8 August 1979 when the domain of integration was dominated by an intense monsoon depression. In order to investigate the model simulation of formative stage of the depression, the model was also integrated using input of 4 July ***, the envelope orography has been constructed and included in the model for investigating its effects on the monsoon prediction. Results of the model forecast are presented and discussed.
