Tolerance Soft Set Relation on a Soft Set and its Matrix Applications
(Ios Press, 2017)In this paper the tolerance soft set relation on a soft set is defined and some examples are given with their matrix representations. Also, pre-class and tolerance class concepts for a given tolerance soft set relation are ... -
New estimators based on order statistics in some families of scale distributions
(Taylor & Francis Inc, 2017)In this study some new unbiased estimators based on order statistics are proposed for the scale parameter in some family of scale distributions. These new estimators are suitable for the cases of complete (uncensored) and ... -
Results on soft continuous functions in the soft topological spaces equipped with soft Scott topology
(Int Scientific Research Publications, 2017)In this study, some properties of soft Scott topology are examined and some relations between soft Scott topology and way below soft set relations are shown. Also the notion of soft Scott continuous function on soft ... -
A biochar-modified carbon paste electrode
(Scientific Technical Research Council Turkey-Tubitak, 2017)The present work examined the use of biochar derived from tea waste as a novel electrode material. For the fabrication of the biochar electrode, suitable amounts of biochar and graphite were mixed with mineral oil for the ... -
Switchable polarisation-independent blue phase liquid crystal Fresnel lens based on phase-separated composite films
(Taylor & Francis Ltd, 2017)A simple method for fabricating a polarisation independent blue-phase liquid crystal Fresnel lens (BPLCFL) is demonstrated by utilising the photo-polymerisation-induced phase separation. The BPLC/polymer binary Fresnel ... -
