We always denote by X our universe, i.e. all the sets we shall consider are subsets of X. Recall some standard notation. 2 everywhere denotes the set of all subsets of a given set X. If A ∩ B = ∅ then we often write A t B rather than A ∪ B, to underline the disjointness. The complement (in X) of a set A is denoted by A. By A4B the symmetric difference of A and B is denoted, i.e. A4B = (A \B) ∪ ...

the aim of this paper is to show how some measures of noncompactness in the banach space of continuous functions defined on two variables can be applied to the solvability of a general system of functional integral equations . the results obtained generalize and extend several equations . an illustrative example is also presented .

in this paper, a novel approach for ranking fuzzy numbers based on the angle measure is introduced. several left and right spreads at each chosen levels of fuzzy numbers is used to determine center of mass points(cmps) and then, the angels between the cmps and the horizontal axis is calculated. the total angle is determined by averaging the computed angles and finally, the novel method is compa...

In this paper, we investigate the efficacy of subdomain testing and random testing using the expected number of failures detected (the E-measure) as a measure of effectiveness. Simple as it is, the E-measure does provide a great deal of useful information about the fault-detecting capability of testing strategies. With the E-measure, we obtain new characterizations of subdomain testing, includi...
