We study the problem of k-visibility in the memoryconstrained model. In this model, the input resides in a randomly accessible read-only memory of O(n) words with O(log n) bits each. An algorithm can read and write O(s) additional words of workspace during its execution, and it writes its output to write-only memory. In a given polygon P , for a given point q ∈ P , we say a point p is inside th...

In the current age, use of natural communication in human computer interaction is a known and well installed thought. Hand gesture recognition and gesture-based applications has gained a significant amount of popularity amongst people all over the world. It has a number of applications ranging from security to entertainment. These applications generally are real time applications and need fast,...

in this study, it has been observed that the natural similarity of the blood flow to both kidneys, despite the differences of length of the right and left renal arteries, is due to the angle of distribution of these arteries. this angle has been determined to be of 66.7 degrees for the left renal artery and only 51.5 degrees for the right renal artery, in their normal anatomical aspects.

This article presents a distance and angle similarity measure. The integrated similarity measure takes the strengths of both the distance and direction of measured documents into account. This article analyzes the features of the similarity measure by comparing it with the traditional distance-based similarity measure and the cosine measure, providing the iso-similarity contour, investigating t...

Geometry with its formal, logical and spatial properties is well suited to be taught in an environment that includes dynamic geometry software (DGSs), geometry automated theorem provers (GATPs) and repositories of geometric problems (RGPs). With the integration of those tools in a given learning environment the student is able to explore the built-in knowledge, but also to do new constructions,...

objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea).   materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...

BACKGROUND The purpose of this study was to test the hypothesis that direct vertebral derotation by pedicle screws (PS) causes hypokyphosis of the thoracic spine in adolescent idiopathic scoliosis (AIS) patients, using computer simulation. METHODS Twenty AIS patients with Lenke type 1 or 2 who underwent posterior correction surgeries using PS were included in this study. Simulated corrections...

In sparse-angle X-ray tomography reconstruction, where only a small number of projection images are taken around the object, appropriate sinogram interpolation has a significant impact on image quality. A novel sinogram interpolation method is introduced for extreme sparse tomographic reconstruction where only nine measured projection images are available. The sinogram is interpolated by solvin...
