statement of the problem: in the evolution of orthodontics, the changes in soft tissue, especially smile line attracts considerable attention. purpose: the present study was carried out to evaluate the correlation of the smile line with the vertical parameters of anterior part of face. materials and methods: forty-six iranian adults, aged between 18-25 years were selected. five quantitative and...

This paper introduces a method to subdivide complex building structures like terraced houses into single house units comparable to units available in a cadastral map. 3D line segments are detected with sub-pixel accuracy in traditional vertical true orthomosaics as well as in innovative oblique true orthomosaics and their respective surface models. Hereby high gradient strengths on roofs as wel...

OBJECTIVE To measure the static visual vertical and the effect of visual rotation on the perception of visual vertical in migraine and vestibular migraine subjects. By so doing, we may better understand the vestibular contribution to the pathophysiology of migraine, as well as the capacity for visual compensation. METHODS The perception of visual vertical in the presence of static and dynamic...

with A,B ∈ k. Then the rational point that comes with the curve is O = (0: 1 : 0), in the projective model Y Z = X +AXZ +BZ. There is a group law on an elliptic curve, given as follows. Let P,Q be points on the curve. Draw the unique line through P and Q (the tangent at P if they are equal) and find the unique third point of intersection, R, with the curve; this exists by Bézout’s theorem. Now ...

We are searching for an unknown horizontal or vertical line in the plane under the competitive framework. We design a well-suited framework for all cylcic strategies that result in two-sequence functionals. For optimizing such functionals we apply a method that combines two main paradigms. The given solution shows that the combination method is of general interest. Finally, we obtain the curren...

It is shown that every orthogonal terrain, i.e., an orthogonal (rightangled) polyhedron based on a rectangle that meets every vertical line in a segment, has a grid unfolding: its surface may be unfolded to a single non-overlapping piece by cutting along grid edges defined by coordinate planes through every vertex.

We present a new application of the acousto-optic superlattice modulation of a fiber Bragg grating based on the dynamic phase and group delay properties of this fiber-optic component. We demonstrate a tunable photonic true-time-delay line based on the group delay change of the light reflected from the grating sidebands. The delay is electrically tuned by adjusting the voltage applied to a piezo...
