In order to assess the patency and function of biliary-enteric anastomoses performed in our Department of Surgery, 21 patients entered the following study, provided an informed consent was obtained. All the patients were affected by benign biliary tract diseases and underwent either Roux-en-Y hepaticojejunostomy (11 cases), or side-to-side choledochoduodenostomy (10 cases). The 21 patients were...

A new miniaturized dominant mode leaky-wave antenna is proposed. This antenna is a transmission line structure with radiating wavenumber increasing from negative to positive values, providing backward to forward scanning capability as frequency is increased. The antenna profile is designed based on microstrip technology using balanced composite right left handed transmission lines (CRLH TL) app...

Through an NEH-funded initiative, Cornell University Library is creating a technical, curatorial, and managerial framework for preserving access to complex born-digital new media objects. The Library's Rose Goldsen Archive of New Media Art provides the testbed for this project. This collection of complex interactive born-digital artworks are used by students, faculty, and artists from various d...

Recommendation is usually reduced to a prediction problem over the function r(ua, ei) that returns the expected rating of element ei for user ua. In the IPTV domain, we deal with an environment where the definitions of all the parameters involved in this function (i.e., user profiles, feedback ratings and elements) are controversial. To our knowledge, this paper represents the first attempt to ...

abstract—digital foot scanners have been developed in recent years to yield anthropometrists digital image of insole with pressure distribution and anthropometric information. in this paper a hybrid algorithm containing gray level spatial correlation histogram and shanbag entropy is presented for analysis of scanned foot images. an evolutionary algorithm is also employed to find the optimum par...

Since decades the evaluation of flaw indications on radiographs from welds or castings are based on well accepted reference film catalogues from organizations like IIW (weldments), ASTM (castings) or DGZfP (D5 recommendation on heavy steel castings). Today, the transformation of classical film radiography to the digital world is in full progress. Some ASTM standards do not permit the evaluation...

--Many watermarking methods for protecting the intellectual property right and authenticating multimedia data have been proposed in recent years. It is possible to guarantee the authenticity of data using readable and fragile watermarking. In this paper, we propose a visible watermarking technique using verifiable digital seal image that is based on the concept of fragile watermarking. Seal ima...

The purpose of this recommendation is to update the Recommendation on Scanning Formats formulated by the RACE Image Communication Project Line 4 in January 1994. This update takes into account the studies performed in WP2 within the framework of the Scanning Formats Extension. This paper also discusses the strategy to follow in order to adopt a progressive format for the coding of digital telev...
