In orthodontics bracket positioning is the key to good results beside good diagnosis and treatment planning. All the advocates of different appliance system laid stress on proper positioning of brackets Accurate bracket placement is very important since it affects torque, tip, in/out , vertical positioning and rotation. The purpose of this article is to review the work of notable orthodontists ...

With the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. However the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. Robot n...

Introduction: The present study was aimed at evaluating common positioning errors on panoramic radiographs taken in the Radiology Department of Mashhad Dental School. Materials and methods: The study sample included 1,990 digital panoramic radiographs taken in the Radiology Department of Mashhad Dental School by a Planmeca Promax (Planmeca Oy, Helsinki, Finland), during a 2-year period (2010–20...

this paper addresses a new product positioning problem, in which prices of the products are simultaneously determined in order to maximize both customer satisfaction and seller’s net profit. in this regard, customer willingness is identified with respect to the products within a family, upon which prices of the products are optimized so as to attain two objective functions: 1) maximizing custom...

today, saving and storing water are among the most critical and important issues which have attracted the world's attention. history of storing water in the form of ghanat and water reservoir by iranians goes back to ancient times. studies on this field show that benefiting from underground dams was one of the methods employed for exploiting water in past times. in countries like iran, due...

In the practical application of the mobile robot, the first encountered problem is positioning. The positioning is an important basic function for an autonomous mobile robot, which is the premise of the robot to complete its mission, and is also currently the closely watched research topic (Meng et al., 2000; Wang et al., 2008; Panzieri et al., 2008). Positioning technology is intended to obtai...

Against to the presence of high complexity, low accuracy and a smaller range of positioning in traditional positioning technologies, A single positioning technology can not completely cover the environment and lead to the problem of inaccurate positioning results,it presents the multiinformation fusion positioning technology for housework robot positioning system. Uncertainties among the acquir...

The purpose of this paper was to study the effect of therapeutic positioning on the functional use of augmentative communication equipment. Recent literature on therapeutic positioning as it affects muscle tone and functional activities is reviewed. The effect of positioning intervention on rate and accuracy of head-controlled typing on an augmentative communication machine was measured. The ra...
