Composite adaptive grid (CAG) methods for solving hyperbolic partial differential equations (PDE's) are discussed in this paper. Composite grids are used at the coarsest level to deal with domains with complicated geometries. Stair step grids developed for composite grids are also used in the ner levels to cover reened regions. New data structures for stair step grids are proposed and implement...

A stacked type stair-case patch antenna with dielectric substrate (εr= 2.33) has been conceived and is theoretically demonstrated. Unlike conventional microstrip antenna it shows remarkable improvement in bandwidth (around 20%) as well as gain (around 10.5 dBi). The proposed structure is designed with two identical stair-case patches. Thorough investigations of the proposed antenna along with t...

Stair-climbing is an important skill for promoting independence and activities of daily life and is a key component of rehabilitation therapies for physically disabled children. This thesis describes the design and evaluation of an interactive musical stairs system for children engaged in stairclimbing physical therapies. The achievement of a targeted therapeutic goal, namely, use of reciprocal...

Explosive-type strength training may alter kinetics and neuromuscular activity during stair ascent in elderly women. This may improve functional ability. Nineteen women (69.7 ± 3.4 yr) were randomly allocated to strength training (TG; twice per wk, 12 wk) or a control group (CG). Stair ascent was assessed at self-chosen (AFV), standardized (ASV), and maximal velocity (AMV) pre- and posttraining...

ISSUE ADDRESSED This study investigated the effectiveness of positive and negative-themed message prompts encouraging stair use at the point of choice between an elevator and stairwell in a professional workplace. METHODS A simple time series design using two control periods assessed the efficacy of positive and negative messages on the pedestrian choice between stairs and an elevator in a re...

fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

background: patellofemoral pain (pfp) is a common affliction and complex clinical entity. deficit in neuromotor control of the core may be a remote contributing factor to the development of pfps. comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(pfps) in a stair stepping task is the aim of...

Understanding flow localization in materials containing high concentrations of Stacking Fault Tetrahedra (SFT’s) depends on delineation of the mechanisms by which they are destroyed as effective dislocation obstacles. The elastic interaction between glissile dislocations and SFT’s in FCC metals is examined, both analytically and numerically. Numerical calculations are performed for both full an...

BACKGROUND Performance tests are important to characterize patient disabilities and functional changes. The Osteoarthritis Research Society International and others recommend the 30-second Chair Stand Test and Stair Climb Test, among others, as core tests that capture two distinct types of disability during activities of daily living. However, these two tests are limited by current protocols of...
