4881   IWEX: A New Ultrasonic Array Technology for Direct Imaging of Subsurface Defects IWEX: A New Ultrasonic Array Technology for Direct Imaging of Subsurface Defects Khalid Chougrani, Niels Pörtzgen    0 Both in new construction and in service, detection, sizing and characterization of defects are essential for integrity assessment of metal components and welds. Ultrasonic Non Destructive Inspection (NDI) using Pulse Echo (PE) technique or Time of Flight Diffraction (ToFD) have been proven to be reliable approaches to assess weld integrity. However, quantitative defect characterization with PE remains challenging because the signal caused by the reflection at the defect is very dependent on defe... 查看全文

4885   Improving information retrieval system by co-clustering web documents and queries Improving information retrieval system by co-clustering web documents and queries    2011 World Wide Web is considered the most valuable place for Information Retrieval and Knowledge Discovery. While retrieving information through user queries, a search engine results in a large and unmanageable collection of documents. A more efficient way to organize the documents can be a combination of clustering and ranking, where clustering can group the documents and ranking can be applied for ordering the pages within each cluster. This paper proposes an approach to co-clustering web document... 查看全文

4887   Synchronous bilateral primary germ cell tumors of the testis: A case report and review of the literature Synchronous bilateral primary germ cell tumors of the testis: A case report and review of the literature Johnny Ray Bernard Jr, Laura A. Vallow, Elizabeth R. DePeri, Rebecca B. McNeil, Deborah G. Feigel, S    2006 Synchronous bilateral primary germ cell tumors of the testis are exceedingly rare. The most common synchronous testicular tumors are seminomas, followed by embryonal carcinomas, teratocarcinomas, and choriocarcinomas. In a series of 385 patients we found nine with bilateral primary germ cell tumors of the testis (2.3%), including one with synchronous involvement of both testes. The treatment of synchronous bilateral primary germ cell tumors of the testis is in principle the same as that of solit... 查看全文

4888   Early hilar lung cancer: Its clinical aspect Early hilar lung cancer: Its clinical aspect Edgar D. Staren, David A. Robinson, Thomas R. Witt and Steven G. Economou    2006 Early hilar lung cancers are rare, but are curable if they are properly diagnosed and treated. In the past 14 years, we have treated 27 patients with early hilar cancers that fulfilled the criteria proposed by the Japanese Lung Cancer Society (JLCS). Eighteen patients presented with symptoms and 9 were detected by the mass screening examination of sputum cytology. All lesions in both groups were finally diagnosed by bronchoscopy. Twenty patients (74%) had positive sputum cytology, whereas only 7... 查看全文

4889   A novel web usage mining method - Mining and clustering of DAG access patterns considering page browsing time A novel web usage mining method - Mining and clustering of DAG access patterns considering page browsing time    2008 In this paper, we propose a novel method to analyze web access logs. The proposed method defines a web access pattern as a DAG with page browsing time, and extracts the patterns using the closed frequent embedded DAG mining algorithm, DIGDAG. The proposed method succeeds in extracting as small number of patterns as necessary minimum, and enables more efficient analysis by clustering the extracted results. 查看全文

4892   From Degenerate Patches to Triangular and Trimmed Patches From Degenerate Patches to Triangular and Trimmed Patches Marc Vigo, Núria Pla, Pere Brunet    1997 CAD systems are usually based on a tensor product representation of free form. surfaces. In this case, trimmed patches are used for modeling non rectangular zones. Trimmed patches provide a reasonable solution for the representation of general topologies, provided that the gap between equivalent trimming curves in the euclidean space is small enough. Several commercial CAD systems, however, represent certain non rectangular surface regions through degenerate rectangular patches. Degenerate patch... 查看全文

4901   Detection of human papilloma virus subtypes 16 and P16ink4a in invasive squamous cell carcinoma of the fallopian tube and concomitant squamous cell carcinoma in situ of the cervix Detection of human papilloma virus subtypes 16 and P16ink4a in invasive squamous cell carcinoma of the fallopian tube and concomitant squamous cell carcinoma in situ of the cervix Garth H. Ballantyne and Jacquelyn Quin    2008 Squamous cell carcinoma (SCC) of the fallopian tube is rare and often diagnosed postoperatively. Cervical cancer is considered as a long-term sequaele, resulting from sexual transmitted infection with certain common high-risk human papilloma virus (HPV) types. The role of human papilloma virus in the development of the tubal SCC is unknown. We report an unusual case of SCC of the fallopian tube, synchronously occurring with cervical SCC in situ in a 49-year-old patient. Histological examination ... 查看全文

4902   Nitrate in Community Water Supplies and Risk of Childhood Type 1 Diabetes in Sardinia, Italy Nitrate in Community Water Supplies and Risk of Childhood Type 1 Diabetes in Sardinia, Italy S;ro Muntoni, Pierluigi Cocco, Sergio Muntoni;Gabriella Aru    2006 We tested the hypothesis of an association between childhood type 1 diabetes (T1D) risk and nitrate concentration in drinking water in Sardinia, Italy, using Poisson regression analysis. Childhood T1D risk showed an inverse trend with increasing quartile of nitrate level in the total population and among men. A nitrate concentration in drinking water below 10 mg/l is unlikely to account for the spatial variation in childhood T1D incidence. 查看全文
