The standard RSA cryptosystem is not semantically secure. Pointcheviel proposed a variant of RSA cryptosystem with the property of semantic security by introducing a new problem known as DRSA problem. He called it DRSA scheme. In this paper, we underlined a shortcoming of that scheme and proposed an alternative DRSA public key cryptosystem.

One of the primary differences between humans and other animals is our capacity for high level cognition and the use of language. Historically, AI has understandably focused on duplicating these aspects of human behavior, and selected its architectures accordingly. However, humans are nevertheless social mammals and share a large part of the mammalian behavior repertoire, such as feeding, as we...

Dominance measuring methods are a recent approach for dealing with complex decisionmaking problems with imprecise, incomplete or partial information within multi-attribute value/utility theory. These methods compute pairwise dominance values and exploit the information included in the dominance matrix in different ways to derive measures of dominance intensity to rank the alternatives under con...

The paper investigates relationships between chemical structure, surface active properties and antibacterial activity of 70 bis-quaternary imidazolium chlorides. Chemical structure and properties of imidazolium chlorides were described by 7 condition attributes and antimicrobial properties were mapped by a decision attribute. Dominance-based Rough Set Approach (DRSA) was applied to discover a p...

In this study, 76 men came into the lab in pairs and engaged in a 7-minute videotaped mate competition for the attention of an attractive female confederate. Pre-competition testosterone (T) levels were positively associated with men’s dominance behaviors and with how much the confederate indicated that she ‘‘clicked’’ with each participant. Dyadic analyses showed that self-reported dominance m...

Dominance-based Rough Set Approach (DRSA) is an extension of classical Rough Set Theory (RST). Approximation of class unions is a very important approach in DRSA. Aiming at the disadvantage of the classical method we presented a new methodology for approximation of class unions based on dominance-matrix. It only needs to calculate the dominance-matrix and does not need to consider the preferenc...

We establish for the first time a formal relationship between dominance graphs, used for modeling semantics, and grammar formalisms with underspecified dominance links, used for modeling syntax. We present a translation of normal dominance graphs into Unordered Vector Grammars with Dominance Links (UVG-DL) and prove that the configurations of the dominance graph correspond to the derivation tre...

knowledge translation is a process that includes synthesis, dissemination, exchange and application of knowledge to improve the health, services and products in this study we have attempted to examine the knowledge translation practice and its perceived barriers on the universalities and research institutes (research sector) in iran.both qualitative and quantitative approaches were used. in the...

This paper presents a knowledge/rule based approach to continuous speech recognition. The proposed recognition system (Samouelian, 1994) uses a data driven methodology, where the knowledge about the structure and characteristics of the speech signal is captured explicitly from the database by the use of inductive inference (C4.5) (Quinlan, 1986). This allows the integration of features from exi...
