Public and private organizations have access to vast amount of internal, deep Web and open Web information. Transforming this heterogeneous and distributed information into actionable and insightful information is the key to the emerging new class of business intelligence and national security applications. Although role of semantics in search and integration has been often talked about, in thi...

There are a lot of pages on internet that are generated dynamically by the back-end database and the traditional searching engines can’t reach these pages, which are called Deep Web. These sources are structured and provide structured query interfaces and results. Organizing structured Deep Web sources by their domain can let users browse these valuable resources and is one of the critical step...

In Deep Web data integration, some Web database interfaces express exclusive predicates of the form Qe = Pi(Pi ∈ P1, P2, . . . , Pm), which permits only one predicate to be selected at a time. Accurately and efficiently estimating the selectivity of each Qe is of critical importance to optimal query translation. In this paper, we mainly focus on the selectivity estimation on infinite-value attr...

The behaviour of the cryogenically treated En52 martensitic valve steel has been experimentally analyzed in this paper. Material samples are subjected to deep cryogenic treatment after completing the regular heat treatment. The critical properties of the valve steel like wear resistance, hardness, tensile strength and impact strength are evaluated for the cryo treated En52 valve steel samples a...

purpose: to compare outcomes of two techniques (anwar vs. melles) of deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: this randomized double-blind clinical trial was performed on 57 eyes of 57 patients with keratoconus. patients aged 20-35 years with a clinical diagnosis of keratoconus who were contact lens intolerant and had corrected distance visual acuity (cd...

the theoretical calculation of the energies of projectile like fragments (plfs) using the heavy-ion reactions between 76ge and 198pt are reported in this article. the incident beam energy was 635 mev. the calculated values of plfs are compared with the previous experimental results and it is shown that the theoretical calculations of plfs are consistent with the experimental values. the elastic...

a5.2 year-old holstein cow was presented with lameness andabnormal weight bearing in a slaughterhouse. widening of theperiople and swelling of the heel area in the lateral claw was morepermanent than the medial claw. vertical fissure (vf) involvingthe coronary band to the middle of the dorsal wall of the medialhind claw was observed. it was also extended to the bearingsurface in the inner surfa...
