THE p-CENTER PROBLEM ON FUZZY NETWORKS AND
REDUCTION OF COST
Sk. Md. Abu
Nayeem
Madhumangal
Pal
Here we consider the
p-center problem on different types of fuzzy
networks. In particular, we are interested in the networks with interval and
triangular fuzzy arc lengths and vertex-weights. A methodology to obtain the
best satisfaction level of the decision maker who wishes to reduce the cost
within the tolerance limits is proposed. Illustrative examples are provided.

INTELLIGENT TECHNIQUE OF CANCELING MATERNAL ECG IN
FECG EXTRACTION
C.
KEZI SELVA VIJIILA
P.
KANAGASABAPATHY
In this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (ANFIS) for canceling maternal electrocardiogram (MECG) in fetal electrocardiogram extraction (FECG).This technique is used to estimate the MECG present in the abdominal signal of a pregnant woman. The FECG is then extracted by subtracting the estimated MECG from the abdominal signal. Performance of the proposed method in terms of mean square error, signal to noise ratio is compared with neural network. Our results show that this method is a simple and powerful means for the extraction of FECG.

In this paper, we establish the theory of fuzzy ideal convergence on
completely distributive lattices and give characterizations of some topological
notions. We also study fuzzy limit structures and discuss the relationship
between fuzzy co-topologies and fuzzy limit structures.

SOME RESULTS OF INTUITIONISTIC FUZZY WEAK DUAL

L.

Zahedi
In this note we consider the notion of intuitionistic fuzzy (weak) dual hyper K-ideals and obtain related results. Then we classify this notion according to level sets. After that we determine the relationships between intuitionistic fuzzy (weak) dual hyper K-ideals and intuitionistic fuzzy (weak) hyper K-ideals. Finally, we define the notion of the product of two intuitionistic fuzzy (weak) dual hyper K-ideals and prove several Decomposition Theorems.

GENERALIZATION OF ($epsilon $, $epsilon $ $vee$ q)−FUZZY SUBNEAR-RINGS AND
IDEALS
P.
Dheena
S.
Coumaressane
In this paper, we introduce the notion of ($epsilon $, $epsilon $ $vee$ q_{k})− fuzzy subnear-ring which is a generalization of ($epsilon $, $epsilon $ $vee$ q)−fuzzy subnear-ring. We have given examples which are ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy ideals but they are not ($epsilon $, $epsilon $ $vee$ q)−fuzzy ideals. We have also introduced the notions of ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzyquasi-ideals and ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy bi-ideals of near-ring. We have characterized($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy quasi-ideals and ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy bi-ideals of nearrings.
