In recent years, seismic design of structures has been undergoing significant changes due to increasing demand for optimization and minimizing the level of damage and reducing the cost of structural repairs. Development of analytical methods and remarkable improvements of computer performance have been among the factors which influenced the design of structures. A lot of research has been condu...

the most conventional method for lateral bracing of steel frames is using diagonal and x steel braces. in conventional method, braces of frame emplace in one bay or more, relative to structural requirement, from first to last story without displace the braces emplacement on height as columnar form. this pattern is a preliminary and simplest bracing template that the generally codes present base...

Purpose To determine if metal artifact reduction can minimize magnetic susceptibility artifacts in the orbits for an eye plaque brachytherapy patient with metallic dental braces. Material and methods A 62-year-old female patient with a choroidal melanoma in the right eye received a 1.5 T magnetic resonance imaging (MRI) simulation for 3D eye plaque brachytherapy planning. The protocol include...

BACKGROUND Shoulder external rotation braces used for patients with a first-time shoulder dislocation are designed with a variety of arm positions in abduction as well as external rotation. However, few studies have focused on their immobilizing performance, comfort, or user-friendliness. Especially, there have been no robust data of shoulder abduction-external rotation (A-ER) braces in compari...

Braces were introduced by Rump to study non-degenerate involutive set-theoretic solutions of the Yang–Baxter equation. To study non-involutive solutions one needs skew braces, a non-commutative analog of braces. In this talk we discuss basic properties of skew braces and how these structures are related to the Yang-Baxter equation. We also discuss interesting connections between skew braces and...

This paper presents a design application of the proposed generalized response spectrum analysis (GRSA)-based seismic optimization method to large metal spatial structure (constructed in Japan) where rigid diaphragm assumption is not available and displacement responses are disproportionally distributed story. It also discusses optimal mixed placement capacity distribution buckling-restrained br...

INTRODUCTION This treatment-outcome assessment objectively compares Invisalign (Align Technology, Santa Clara, Calif) treatment with braces. METHODS This study, a retrospective cohort analysis, was conducted in New York, NY, in 2004. Records from 2 groups of 48 patients (Invisalign and braces groups) were evaluated by using methods from the American Board of Orthodontics Phase III examination...
