Abstract The well-known $$\mathcal {E}$$ E -set introduced by Hayman in 1960 is a countable collection of Euclidean discs the complex plane, whose subtending angles at origin have finite sum. An important special case an known as R -set, for which sum diameters finite. These sets appear numerous papers theori...

This study examined the reliability of newly developed ground reaction force asymmetry index (GRF AI) at seat-off using a low-cost plate and validity this new test by comparing it with other muscle strength-measuring methods walking speed. was cross-sectional design in general hospital setting. A convenience sample 47 community-dwelling adults aged ≥40 years performed. GRF AI is measurement val...

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 these and the sets $lambda^{f}_{s}(x)$, $gamma^{f}_{s}(x)$ introduced in ~cite{ayt:slpsfn} by aytar [...

In this paper we introduce the concept of $(1,2)^*$-sb-separated sets and $(1,2)^*$-soft b-connected spaces and prove some properties related to these break topics. Also we disscused the properties of $(1,2)^*$-soft b- compactness in soft bitopological space

in this paper, we construct two fuzzy sets using the notions of level subsets and strong level subsets of a given fuzzy set in a ring r. these fuzzy sets turn out to be identical and provide a universal construction of a fuzzy ideal generated by a given fuzzy set in a ring. using this construction and employing the technique of strong level subsets, we provide the shortest and direct fuzzy set ...
