importance of security and sense of peace is a one of the most important factors of urban environment. therefore, the necessity of security in urban spaces has caused the emergence of authentic theories like defensible spaces and crime prevention through environment design (cpted)*. in this paper, various literatures related to defensible space theories have been reviewed and the related keywor...

things (substances, events, abstractions); Corbett (2000, chap. 3) reviewed the relevant evidence regarding linguistic number. Because less imageable referents have less discernible internal boundaries, they may tend to be construed as units even when they are potentially ambiguous in notional number (Eberhard, 1999). Ambiguities in notional number result from conflicts in valuation that can co...

POSTER ABSTRACT—Quantum Key Distribution (QKD) is an innovative technology which exploits the laws of quantum mechanics to generate and distribute unconditionally secure shared key for use in cryptographic applications. While QKD offers the promise of unconditionally secure key distribution, real world systems are built from non-ideal components which necessitates the need to understand the imp...
