or Introduction Details of a planning study for USAF computer security requirements are presented. An Advanced development and Engineering program to obtain an open-use, multilevel secure computing capability is described. Plans are also presented for the related developments of communications security products and the interim solution to present secure computing problems. Finally a Exploratory...

Private information retrieval (PIR) schemes enable a user to access one or more servers that hold copies of a database and privately retrieve parts of the n bits of data stored in the database. This means that the queries give each individual database no partial information (in the information theoretic or computational sense) on the identity of the item retrieved by the user. All known PIR sch...

Keyword advertising, or “sponsored links” that appear alongside online search results or other online content, has grown into a multibillion-dollar market. Providers of keyword advertising, such as Google and Yahoo, profit by auctioning keywords to advertisers. An issue of increasing importance for advertising providers is the “share structure” problem—that is, of the total available resources ...

In this paper we introduce a minimalist hypothesis for keywords extraction: keywords can be extracted from text documents by considering concepts underlying document terms. Furthermore, central concepts are individuated as the concepts that are more related to title concepts. Namely, we propose five metrics, that are diverse in essence, to compute the centrality of concepts in the document body...

•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

background: basic science studies evaluation is important feature for an effective implementation of diabetes research and funding policy. this study aimed to provide an evaluation of diabetes basic research output up to 2015 in iran. methods: data were retrieved from scientific search engine including pubmed, web of science, scopus as well as iranian science databases including sid, iranmedex,...

background: most research on autonomic dysfunction of diabetes mellitus is conducted on ganglions innervating gastrointestinal (gi) tract and there are limited works focusing on cervical sympathetic ganglia. the effects of diabetes mellitus (dm) on the neurons of superior cervical sympathetic ganglion (scsg) are investigated by stereological methods.   material and methods: female rats (n=72) r...

Background: Diabetes is one of the leading causes morbidity and mortality worldwide various studies have shown that people with diabetes are more prone to suffer from dry eye disease than those without diabetes. This study was undertaken aim find prevalence in patients type 2 mellitus correlation between glycemic control of dry eye. Methods: carried out over a period year cases were selected at...
