Industries such as telecomm and avionics have long enjoyed a perk that most other industries do not enjoy: access to accurate operational profiles. Most other industries are left hypothesizing about how they believe the majority of their users will interact with a particular software package. If these guesses are wrong, reliability predictions based on the guesses will likely be wrong as well. ...

Introduction: Sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. The aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. Materials and methods: ...

Abstract Properly assessing the underlying physics of failure is critical in predicting long term reliability electronic packages their intended field applications, yet traditional demonstration methods are complicated by time and cost considerations as well deterministic inadequacies when considering thermomechanical failures. In this work, an alternative testing apparatus associated protocol ...

Background & Aim: Fatigue is a significant problem during pregnancy that has rarely been studied, and may increase the number of caesarean deliveries and preterm births. Reflexology can be utilized for decrease of fatigue. Therefore this study was aimed to identify the effect of sole reflexology on pregnant women’s fatigue severity. Methods & Materials: This research was a clinical trail study ...

Calls for „holistic‟ responses to halt the increasing imprisonment of women are continually reiterated. Solutions are sought which aim to be both „gender-responsive‟ and „community-based‟, however the absence of meaningful definitions of „community‟ and „holistic‟ means that superficial responses are often put in place in response to failures of the system. Taking as an example one attempt to i...

In this study the focus is on the role of local communities in the management of protected areas with the expectation that without the cooperation and assistance of local communities achieving biodiversity conservation in places where the land and resources are fundamental to supporting people’s livelihoods will be less successful than if the local people actively support this goal. Management ...

To obtain the characteristic life of a chain tool magazine and automatic tool changer under normal working condition, a small-sample accelerated life test method was developed. The inverse power law model and small-sample virtual augmented theory was applied while taking vibration as the accelerated stress. The accelerated life test of the automatic tool changer was carried out under different ...

This paper presents experimental evidence that gestural planning systems associated with stressed syllables are more highly activated than ones associated with unstressed syllables. A stop-signal experiment was conducted to investigate how syllable stress and metrical structure influence the ability to halt speech in mid-utterance. Subjects produced three sentences with controlled metrical patt...
