background: in the recent years, using health technologies to diagnose and treat diseases has had a considerable and accelerated growth. the proper use of these technologies may considerably help in the diagnosis and treatment of different diseases. on the other hand, unlimited and unrestricted entry of these technologies may result in induced demand by service providers. the aim of this study ...

AIM: To evaluate the safety and efficacy of posterior scleral application (a modified technique) an antimetabolite mitomycin C-soaked sponge in trabeculectomy for patients with glaucoma. METHODS: This retrospective study included 101 (115 eyes) glaucoma (aged 12–83y) who underwent using a placement method. A piece 3.5×10 mm2 was placed vertically posteriorly long side perpendicular to limbus. T...

We present several examples of programs which ee-ciently monitor the answers from queries performed on data structures to determine if any errors are present. Our paper includes the rst eecient on-line error monitor for a data structure designed to perform nearest neighbor queries. Applications of nearest neighbor queries are extensive and include learning, categorization, speech processing , a...

A very fast mesh simplification algorithm based on halfedge collapse is proposed in this work with a focus on progressive graphic transmission applications. We generalize the Quadric Error Metric (QEM) method to accommodate new topological operations. A flatness criterion is combined with the defined metric to preserve the visual quality of simplified meshes. We further adopt the vertex-based p...

This paper applies a matrix-analytic approach to analyze both the long-term and the short-term loss behaviors of a queue with space priority scheme. Five related performance measures are derived from conditional statistics, including the long-term highpriority and low-priority packet loss probabilities, and the three short-term measures — the average length of a critical period, the average len...
