Spectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants
Volume 10, Issue 6 , November and December 2013, Pages 1-19
Abstract
The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum ... Read MoreA Compromise Ratio Ranking Method of Triangular Intuitionistic Fuzzy Numbers\\ and Its Application to MADM Problems
Volume 10, Issue 6 , November and December 2013, Pages 21-37
Abstract
Triangular intuitionistic fuzzy numbers (TIFNs) is a special case of intuitionistic fuzzy (IF) set and the ranking of TIFNs is an important problem. The aim of this paper is to develop a new methodology for ranking TIFNs by using multiattribute decision making methods (MADM). In this methodology, the ... Read MoreThe optimum support selection by using fuzzy analytical hierarchy process method for Beheshtabad water transporting tunnel in Naien
Volume 10, Issue 6 , November and December 2013, Pages 39-51
Abstract
The engineers can frequently encounter with the situation to select the optimum option among the alternatives related with tunneling operations. The optimum choice can be selected by the experienced engineers taking into consideration their judgment and intuition. However, decision-making methods can ... Read MoreOn Lacunary Statistical Limit and Cluster Points of Sequences of Fuzzy Numbers
Volume 10, Issue 6 , November and December 2013, Pages 53-62
Abstract
For any lacunary sequence $\theta = (k_{r})$, we define the concepts of $S_{\theta}-$limit point and $S_{\theta}-$cluster point of a sequence of fuzzy numbers $X = (X_{k})$. We introduce the new sets $\Lambda^{F}_{S_{\theta}}(X)$, $\Gamma^{F}_{S_{\theta}}(X)$ and prove some inclusion relaions between ... Read MoreOn $\varphi $-Contractions in Fuzzy Metric Spaces with Application to the Intuitionistic Setting
Volume 10, Issue 6 , November and December 2013, Pages 63-72
Abstract
We obtain two fixed point theorems for a kind of $\varphi $-contractions incomplete fuzzy metric spaces, which are applied to easily deduceintuitionistic versions that improve and simplify the recent results of X.Huang, C. Zhu and X. Wen. Read MoreSome (Fuzzy) Topologies on General\\ Fuzzy Automata
Volume 10, Issue 6 , November and December 2013, Pages 73-89
Abstract
In this paper, by presenting some notions and theorems, we obtaindifferent types of fuzzy topologies. In fact, we obtain someLowen-type and Chang-type fuzzy topologies on general fuzzyautomata. To this end, first we define a Kuratowski fuzzy interioroperator which induces a Lowen-type ... Read MoreMeasures of fuzzy semicompactness in $L$-fuzzy topological spaces
Volume 10, Issue 6 , November and December 2013, Pages 91-100
Abstract
In this paper, the notion of fuzzy semicompactness degrees isintroduced in $L$-fuzzy topological spaces by means of theimplication operation of $L$. Characterizations of fuzzysemicompactness degrees in $L$-fuzzy topological spaces areobtained, and some properties of fuzzy semicompactness degrees ... Read MoreThe number of Fuzzy subgroups of some non-abelian groups
Volume 10, Issue 6 , November and December 2013, Pages 101-107
Abstract
In this paper, we compute the number of fuzzy subgroups of some classes of non-abeilan groups. Explicit formulas are givenfor dihedral groups $D_{2n}$, quasi-dihedral groups $QD_{2^n}$, generalized quaternion groups $Q_{4n}$ and modular $p$-groups $M_{p^n}$.

Volume 10, Issue 6 , November and December 2013, Pages 109-124
Abstract
module over a ring is a general mathematical concept for many examples of mathematicalobjects that can be added to each other and multiplied by scalar numbers.In this paper, we consider a module over a ring as a universe and by using the notion of reference points, we provide local approximations ... Read MoreAn explicit formula for the number of fuzzy subgroups of a finite abelian $p$-group\\ of rank two
Volume 10, Issue 6 , November and December 2013, Pages 125-135
Abstract
Ngcibi, Murali and Makamba [Fuzzy subgroups of rank two abelian$p$-group, Iranian J. of Fuzzy Systems {\bf 7} (2010), 149-153]considered the number of fuzzy subgroups of a finite abelian$p$-group $\mathbb{Z}_{p^m}\times \mathbb{Z}_{p^n}$ of rank two, andgave explicit formulas for the cases when $m$ is ...

Volume 10, Issue 6 , November and December 2013, Pages 137-151
Abstract
The purpose of this paper is to study the fuzzy fractional differentialequations. We prove that fuzzy fractional differential equation isequivalent to the fuzzy integral equation and then using this equivalenceexistence and uniqueness result is establish. Fuzzy derivative is considerin the Goetschel-Voxman ... Read MoreThe Remak-Krull-Schmidt Theorem on\\ Fuzzy Groups
