this study presents the nannostratigraphy and nannofossil events in the lower boundary of kalat formation in the east and west of the kopeh- dagh basin. the kalat formation comprises of coarse grained detritus limestone with subordinate sandstone intercalations. in the current study, six sections have been chosen in the east and west of the basin which are as follow: dobaradar section, kalat se...

In settings where R&D specialists work together on a technical project without physically being together, boundary objects are often used to facilitate understanding and collaboration (Carlile, 2002; Star & Griesemer, 1989). From a practice perspective, boundary objects refer to artifacts that are understood within their local setting, yet have enough common ground to facilitate the shared prac...

in this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plates is presented using higher order shear deformation theory. the face sheets are orthotropic laminated composite that follow the first order shear deformation theory (fsdt) based on rissners-mindlin (rm) kinematics field. based on energy method and hamilton's principle, the ...

In the recent era of AI, instance segmentation has significantly advanced boundary and object detection especially in diverse fields (e.g., biological environmental research). Despite its progress, edge amid adjacent objects organism cells) still remains intractable. This is because homogeneous heterogeneous are prone to being mingled a single image. To cope with this challenge, we propose weig...
