To counter range gate pull off (RGPO) and range gate pull in (RGPI) jammings, a multiple hypothesis tracker (MHT) using amplitude information is presented in this paper. A common angle gate test is performed to detect RGPO/RGPI. Then, the problem of MHT is reformulated to take the detected RGPO/RGPI deception measurements into account. And the amplitude information is incorporated in the calculation...
CBTC (Communication Based Train Control) will be based on mobile communication, which the key problem is how to support reliability of control data transmission to improve track utilization and enhance train safety. This paper proposed a kind of real-time transmission model for high speed train end-to-end control data operation, which based on circuit switched data service by traditional wireless...
Performance of workflow schema including overlapping patterns can not be computed by regular reducing approaches, and that excluding overlapping patterns from workflow schema will lose flexibility in schema design, introduce redundant nodes, and make it difficult to describe complex business process. To solve this problem, the concept of generalized well-formed workflow was proposed, in which overlapping...
This paper addresses the traffic grooming problem in wavelength-division multiplexing (WDM) mesh networks. We first introduce a transceiver saving auxiliary graph model, in which various grooming policies can easily be achieved by assigning weight values for various edges. Then we propose a resource efficient grooming policy (REGP) based on the graph model, which take into account the wavelength constraint...
In this paper, we propose a hybrid approach for the automatic three-dimensional segmentation of coronary arteries using multi-scale vessel filtering and a Bayesian probabilistic approach in a level set image segmentation framework. The initial surface of the coronaries is obtained from the multiscale vessel filter response, and the surface then evolves to capture the exact boundary of the coronaries...
In this note, we present an approach for developing patient-specific 3D models of portal veins to provide geometric boundary conditions for computational fluid dynamics (CFD) simulations of the blood flow inside portal veins. The study is based on MRI liver images of individual patients to which we apply image registration and segmentation techniques and inlet and outlet velocity profiles acquired...
