Abstract Introduction: dilaceration is a disturbance in tooth formation that produces a sharp bend or curve in the tooth. this anomaly has a negative effect on the treatment of root canals, orthodontics and surgery. The aim of this study was to determine the prevalence of root dilaceration using Cone Beam Tomography (CBCT). Materials and Methods:In this study, a total of 206 CBCT images(5434t...
We present a novel way to draw planar graphs with good angular resolution. We introduce the polar coordinate representation and describe a family of algorithms for constructing it. The main advantage of the polar representation is that it allows independent control over grid size and bend positions. We first describe a standard (Cartesian) representation algorithm, CRA, which we then modify to ...
Much work on orthogonal graph drawing has focused on 4-planar graphs, that is planar graphs where all vertices have maximum degree 4. In this work, we study aspects of the Kandinsky model, which is a model for orthogonal graph drawings of higher-degree graphs. First, we examine the decision problem β-Embeddability, which asks whether for a given planar graph with a fixed or variable embedding, ...
In this work we study the limits of miniaturization a 90-degree hybrid coupler working in L, C and S bands, with respect to number performance parameters aimed at its application for balanced detection. We investigate main effects responsible degradation devices during miniaturization, establish minimal dimension that such can have without significant photonic applications as The miniaturized d...
In this work, many ways of communications are used between human and computer, while using gesture is considered to be one of the most natural way in a virtual reality system. Because of its intuitiveness and its capability of helping the hearing impaired or speaking impaired, we develop a gesture recognition system. The Hand Talk glove is a normal, cloth driving glove fitted with flex sensors....
