This document describes schema for representing X.509 certificates, X.521 security information, and related elements in directories accessible using the Lightweight Directory Access Protocol (LDAP). The LDAP definitions for these X.509 and X.521 schema elements replaces those provided in RFC 2252 and RFC 2256. 1. Background and Intended Use This document provides LDAP [Roadmap] schema definitio...

This paper describes the development of a procedure for Pb(II) ions removal from various water samples after magnetic solid phase extraction (MNPs) by magnetite nanoparticles (Fe3O4 NPs) modified with sodium dodecyl sulfate (SDS) and pyrrolidine-1-dithiocarboxylic acid ammonium (PDTCAA). The synthesis of Fe3O4 NPs was certified by characterization techniques including field emission scanning el...

We present the RGAI systems which participated in the third Web People Search Task challenge. The chief characteristics of our approach are that we focus on the raw textual parts of the Web pages instead of the structured parts, we group similar attribute classes together and we explicitly handle their interdependencies. The RGAI systems achieved top results on the attribute extraction subtask,...

Authentication is the art of confirming the truth of an attribute of an entity. Entity may be a person. If a entity is a person it can authenticate with the help of its traits such as his facial attribute, fingerprinting attribute, retina attribute, palm attribute, signature of a person, password, token attributes etc. There are so many attacks to which these techniques are vulnerable. So, toda...

According to the characteristics of the large amount of QAR data,such as many parameters, time constraints, strong randomness and the problems of discrete data, together with attribute reduction and rules colleting during QAR anomaly detection, the paper proposed a anomaly detection algorithm of QAR data based on attribute support of rough set. Firstly, we discrete QAR data after converting the...
