This paper presents a vehicle detection method which can divide overlap vehicles. The proposed method detects vehicles by finding vertical planes above a road plane. At first, two horizontal line segments adjacent vertically are detected in the present frame. Then, corresponding line segments are searched in the previous frame by a correlation matching. If the motion of these horizontal line se...

Background and aim: Considering the widespread development of implants in dental treatment plans, linear measurements on panoramic radiography are of especial importance. In the present study we investigated the effect of head misalignment up to 15° around vertical and horizontal axes on the magnification rate of digital panoramic radiography in each part of upper and lower jaws. Materia...

The inverted-T illusion was studied by the magnitude estimation method. The horizontal line in the inverted T is perceptually shorter than the same horizontal line presented singly, and the vertical line in the inverted T is perceptually longer than the same vertical line presented singly. Thus, the inverted·T illusion is due to both a perceptual lengthening of the vertical line and a shortenin...

To bridge the gap between high and low fidelity numerical modeling tools for vertical-axis (or cross-flow) turbines (VATs or CFTs), an actuator line model (ALM) was developed and validated for both a high and a medium solidity vertical-axis turbine at rotor diameter Reynolds numbersReD ∼ 10. The ALM is a combination of classical blade element theory and Navier–Stokes based flow models, and in t...

BACKGROUND The aim of this study was to verify the intra-individual reproducibility of natural head position (NHP) in centric relation (CR) position, to prove the inter-individual differences in the Frankfort horizontal plane and sella-nasion line compared with the true horizontal line, and to establish linear norms from A-point, B-point, Pog as well as soft tissue A-point, soft tissue B-point,...

in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...

A plane graph is a planar graph with a fixed planar embedding in the plane. In a boxrectangular drawing of a plane graph, every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal line segment or a vertical line segment, and the contour of each face is drawn as a rectangle. A planar graph is said to have a box-rectangular drawing if at least one of its plane ...
