Also, we create ruled surfaces whose base curves are the curve with vanishing weighted curvature and the ruling curves are Smarandache curves of this curve. Then, we give some characterizations about these ruled surfaces by obtaining the mean curvatures, Gaussian curvatures, distribution parameters and striction curves of them.eninfo:eu-repo/semantics/closedAccessSpace with densityWeighted curvatureRuled SurfaceArticle41468369510.5831/HMJ.2019.41.4.683WOS:000510864100002N/A
