Methods of Debonding Ceramic Brackets
British Journal of Orthodontics, 1992The problem of debonding ceramic brackets is still one which concerns the orthodontist. It is advisable to use the manufacturers recommended method of debonding each particular type of bracket. The risks of using such brackets need to be carefully assessed against the benefits. Risks can be minimized by carefully assessing the patient and the dentition,

The Method of Brackets in Experimental Mathematics
2018© 2018 by World Scientific Publishing Co. Pte. Ltd. All Rights Reserved. The method of brackets is a new method originally developed in the context of definite integrals coming from the evaluation of Feynman diagrams. It consists on a small number of heuristic rules. The work presented here describes these rules and illustrates the method. The example

An Optimal Design Method for Radar Brackets
Advanced Materials Research, 2011The purpose of this work is to present an optimal design method for radar brackets to get the lightest structure with stiffness constraint. Current radar brackets usually have conservative strength and excessive weight which influences the mobility of radar greatly as they are not optimized in the conceptual design stage.

High‐order iterative bracketing methods
International Journal for Numerical Methods in Engineering, 2013SUMMARYThis paper presents high‐order, single‐point, iterative methods for the numerical solution of the general non‐linear equilibrium equation. The methods are designed so that the approximations provided by the iterative process alternate about the targeted root, thus providing progressively better upper, as well as lower bounds on the sought root ...

An implementation of the method of brackets for symbolic integration
ACM Communications in Computer Algebra, 2011In spite of being a classical problem, the current techniques available for Symbolic Integration are not sufficient to evaluate a variety of integrals coming from Mathematical Physics, such as Bessel functions. The Method of Brackets [2, 3], a heuristic process appearing in the evaluation of Feynman diagrams, can be used to evaluate symbolically a ...

Interactive Virtual Bracket Positioning Method in Orthodontics
2020In the process of orthodontics, accurate bracket positioning is a necessary condition to quickly obtain the ideal treatment result. We propose a virtual bracket-interaction method based on the Layered Depth-Normal Images (LDNI) and the point set matching.

Debonding of ceramic brackets by a new scanning laser method
American Journal of Orthodontics and Dentofacial Orthopedics, 2010The purpose of this in-vitro study was to develop a new method to debond ceramic brackets by scanning with an Er:YAG laser.Sixty bovine mandibular incisors were randomly divided into 2 groups of 30. Polycrystalline ceramic brackets were placed on their labial surfaces by using the orthodontic composite adhesive Transbond XT (3M Unitek, Monrovia, Calif)

Test method for the vibration response of a vehicle horn bracket
2015 4th International Conference on Computer Science and Network Technology (ICCSNT), 2015In order to solve the problem that trumpets of some vehicles during working lead to vibrations of steering wheel in cab, according to the power flow method, the model of vibration system is established. The vibration influence of holder's length to response points is analyzed by using the equivalent theorem of Norton.
