In this paper we propose a new cephalometric x-ray registration technique based on angular radial transform (ART). The registration is used as a first step in most hybrid cephalometric landmark detection algorithms to find the approximate landmark locations which are further used to find the exact landmark locations in the test x-ray image. All the existing cephalometric algorithms use features...

This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopa...

We report on the discovery of a group of local A-type blue horizontal-branch (HBA) stars moving in a prograde, comet-like orbit with very similar kinematics and abundances. This serendipitously discovered group contains 5 or 6 local HBA stars venturing very close to the Galactic centre; their [Fe/H] is around −1.7, and they seem to present minimum scatter in at least Mg, Si, Ti, Fe, Al, and Cr ...

The topspin forehand is the most frequent and effective shot in top-level table tennis matches. present study assesses biomechanical differences stroke technique when incoming ball different rotations. Eight national level-1 male athletes (176.6 ± 4.8 cm, 70.8 6.6 kg, 20.9 2.4 yr) performed two kinds of techniques—topspin strokes against (AT) backspin (AB) balls, respectively. kinematic paramet...

ABSTRACT Objective: To analyze the cervical sagittal parameters of patients with rheumatoid arthritis (RA) and compare them obtained from healthy in a sample Brazilian population. Methods: Epidemiological data were collected 72 radiographs spine plane evaluated by measuring COG-C7 (distance measured between center gravity head C7 plumb line -cranial offset), C2-C7 lordosis (vertebrae C2 to C7),...

The study of topological indices in graph theory is one the more important topics, as scientific development that occurred previous century had an impact by linking it to many chemical and physical properties such boiling point melting point. So, our interest this paper “generalized indices’ network” for some graphs have somewhat strange structure, so called cog-graphs special “molecular networ...

The system dynamics technique has been demonstrated to be a proper method by which to model and simulate the development of spatial data infrastructures (SDI). An SDI is a collaborative effort to manage and share spatial data at different political and administrative levels. It is comprised of various dynamically interacting quantitative and qualitative (linguistic) variables. To incorporate li...

Falling due to unstable standing balance is considered to be the main cause of bone fractures, which lead elderly persons to becoming bedridden. Thus, the standing balance of elderly persons is being given increasingly greater attention. On the other hand, postural deformation caused by deformation in the spine and lower leg joints is considered to have an effect on standing balance. The object...
