The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of Hot-spot stress (HSS), but is also significantly influenced by the through-the-thickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stres...

Input queued and combined input/output queued switching architectures must be controlled by a scheduling algorithm, which solves contention in the transfer of data units to switch outputs. We consider the case of packet switches (or routers), i.e., devices operating on variable-size data units at their interfaces, assuming that they internally operate on fixed-size data units, and we propose no...

We present a new approach for the coarse segmentation of tubular structures in 3D image data. Our algorithm, which requires only few initial values and minimal user interaction, can be used to initialise complex deformable models and is based on an extension of the randomized Hough transform (RHT), a robust method for low-dimensional parametric object detection. By means of a discrete Kalman fi...

We introduce a new approach for tracking-based segmentation of 3D tubular structures. The approach is based on a novel combination of a 3D cylindrical intensity model and particle filter tracking. In comparison to earlier work we utilize a 3D intensity model as the measurement model of the particle filter, thus a more realistic 3D appearance model is used that directly represents the image inte...

In this paper, we propose a novel tubular structure segmentation method, which is based on an intensity-based tensor that fits to a vessel. Our model is initialized with a single seed point and it is capable of capturing whole vessel tree by an automatic branch detection algorithm. The centerline of the vessel as well as its thickness is extracted. We demonstrated the performance of our algorit...

Sir, Tubular adenoma is a benign breast lesion, typically presenting as a palpable breast mass in a young woman. We present a novel case of tubular adenoma presenting as an intraductal mass, the first described case in the literature to our knowledge. There is limited information regarding the spectrum of imaging findings of this entity in the literature, which can pose a diagnostic and managem...
