BACKGROUND Both genetic and environmental factors play roles in pathogenesis of esophageal squamous cell carcinoma (ESCC) and susceptibility may be modified by functional polymorphisms in folate metabolic genes, such as methylenetetrahydrofolate reductase (MTHFR). We here aimed to evaluate associations of MTHFR C677T and A1298C polymorphisms with ESCC. (More)
Iris segmentation is an important step for automatic iris recognition. This paper presents a new iris segmentation method based on K-means clustering. we propose a limbic boundary localization algorithm based on K-Means clustering for pupil detection. We locates the centers of the pupil and the iris in the input image. Then two image strips containing the(More)
—Current system managers often have to process huge amounts of alerts per day, which may be produced by all kinds of security products, network management tools or system logs. This has made it extremely difficult for managers to analyze and react to threats and attacks. So an effective technique which can automatically filter and analyze alerts has become(More)
Accurate and sufficient range measurements are essential for range-based localization in wireless sensor networks. However, noise and data missing are inevitable in distance ranging, which may degrade localization accuracy drastically. Existing localization approaches often degrade in terms of accuracy in the co-existence of incomplete and corrupted range(More)
a r t i c l e i n f o This paper presents a diagnostic Bayesian network (DBN) for fault detection and diagnosis (FDD) of variable air volume (VAV) terminals. The structure of the DBN illustrates qualitatively the casual relationships between faults and symptoms. The parameters of the DBN describe quantitatively the probabilistic dependences between faults(More)
Wireless multimedia sensor networks have become the focus of research in a wide variety of areas in recent years. The camera sensor nodes observe the phenomenon at different locations in the field, and the spatially proximal cameras could have highly overlapped field of views (FoVs). Based on the three-dimensional sensing model of camera sensor node, a FoVs(More)
