A new circle detection algorithm based on the gradient of the intensity image is proposed. The method relies on two conditions. The “gradient angle compatibility condition” constraints the gradient of a given percentage of the pixels belonging to some digital circles of radius in the range of radii to detect to point towards the centre of the circle or in the opposite direction. The “curvature ...

Objectives: To examine the influence of enhanced expectancies on motor learning, we manipulated learners' expectancies by providing criteria for “success” that were relatively easy or difficult to meet. Design: Experimental design with two groups. Method: Two groups of non-golfers practiced putting golf balls to a target from a distance of 150 cm. The target was surrounded by a large (14 cm dia...

We develop a matrix model for the SO(32) Heterotic string with certain Wilson lines on the lightlike circle. This is done by using appropriate T-dualities. The method works for an infinite number of Wilson lines, but not for all. The matrix model is the theory on the D-string of type I wrapped on a circle with a SO(32) Wilson line on the circle. The radius of the circle depends on the Wilson li...

this research is intended to present an elucidation of interaction between textual context and circumstantial context while comprehending the text. this interaction is maintained in a specific hermeneutic circle of comprehending the text. the qur’ān is divine word and has characteristics that demands hermeneutic circle proportionate to it. therefore, in this research the characteristics influen...

This study focuses on the development of triangular fuzzy numbers, the revising of triangular fuzzy numbers, and the constructing of a HCFN (half-circle fuzzy number) model which can be utilized to perform more plural operations. They are further transformed for trigonometric functions and polar coordinates. From half-circle fuzzy numbers we can conceive cylindrical fuzzy numbers, which work be...

In this paper we present a numerical method to compute derivatives of the rotation number for parametric families of circle diffeomorphisms with high accuracy. Our methodology is an extension of a recently developed approach to compute rotation numbers based on suitable averages of iterates of the map and Richardson extrapolation. We focus on analytic circle diffeomorphisms, but the method also...

Ultra wide band (UWB) microwave imaging has recently been proposed for detecting small malignant breast tumors and is expected to detect breast tumors with safety, comfort and precision for high resolution of UWB pulse. In this paper, we propose a new imaging method that uses circle approximation to detect the cancer in order for automatically detection without doctors’ analysis. Our proposal m...
