INTRODUCTION The physiological response during the endurance shuttle walk test (ESWT), the cycle endurance test (CET) and the incremental shuttle walk test (ISWT) remains unknown in PAH. We tested the hypothesis that endurance tests induce a near-maximal physiological demand comparable to incremental tests. We also hypothesized that differences in respiratory response during exercise would be r...

This study aims to develop seismic fragility curves for a typical pile-supported wharf. Fragility curve is one of the popular tools in seismic performance evaluation of a structure. The software FLAC2D was used to simulate the seismic performance of the wharf structure. Using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (IDA) was applied for sei...

In an earlier paper, we described a data structure, called support graph, for efficient incremental evaluation of tabled logic programs. The support graph records the dependencies between answers in the tables, and is crucial for efficiently propagating the changes to the tables when facts are deleted. Incremental computation with support graphs are hundreds of times faster than from-scratch ev...

Dynamic hyperinflation has important clinical consequences in patients with chronic obstructive pulmonary disease (COPD). Given that most of these patients have respiratory and peripheral muscle weakness, dyspnea and functional exercise capacity may improve as a result of inspiratory muscle training (IMT). The aim of the study was to analyze the effects of IMT on exercise capacity, dyspnea, and...

in the conventional design and analysis methods affecting parameters (loads, materials'strength, etc) are not set as probable variables. safety factors in the current codes andstandards are usually obtained on the basis of judgment and experience, which may beimproper or uneconomical. in technical literature, a method based on nonlinear static analysisis suggested to set reliability index on st...

objectives: investigating the effect of endurance training program onthe gait pattern of non-active elderly people. methods & materials: this study has been done by a semi-experience method with 23 old men and women by the average and standard deviation of 70/50±6/9 years old (n=14 people of exercise group, n=9 people of control group). the exercise group took part in this program for eight wee...
