In this paper, we present a new algorithm for clustering data in large datasets using image processing approaches. First the dataset is mapped into a binary image plane. The synthesized image is then processed utilizing efficient image processing techniques to cluster the data in the dataset. Henceforth, the algorithm avoids exhaustive search to identify clusters. The algorithm considers only a...

BACKGROUND Due to complex pelvic geometry, percutaneous screw placement in the posterior acetabular column can pose a major challenge even for experienced surgeons. METHODS The present study examined the preformed bone stock of the posterior acetabular column in 260 hemipelvises. Retrograde posterior column screws were virtually implanted using iPlan CMF (BrainLAB AG, Feldkirchen, Germany); m...

The accuracy of quantitative stereological analysis tools such as the (physical) disector method substantially depends on the precise determination of the thickness of the analyzed histological sections. One conventional method for measurement of histological section thickness is to re-embed the section of interest vertically to its original section plane. The section thickness is then measured...

With the aid of a new research facility, transient pressures have been measured on the upper surface of a narrow-delta wing when it entered a sharp-edged gust normal to the wing plane. This paper describes the facility and presents an analysis of the results of six runs through the gust by one model. It is shown that the pressure distribution on any particular cross-section of the wing remains ...

Software Defined Networking (SDN) introduces programability into the network forwarding plane and simultaneously enables architectural refactoring of the routing control plane. In this work, we present two complementary studies leveraging the opportunities presented by SDN. First, in the context of internet router architectures in Section II, we propose leveraging OpenFlow forwarding informatio...

The scattering characteristic of paraxial gaussian beam from two dimensional dielectric rough surfaces is studied in this paper. The modification of the Kirchhoff approximation theory for rough surface scattering by an incident gaussian beam instead of a plane wave are developed based on conventional Kirchhoff scattering theory and plane wave spectrum expansion method. The coherent and incohere...
