Wizard-of-Oz (WOZ) simulations are a popular means for investigating the properties of human-computer interaction. In this paper the findings from a WOZ experiment for evaluating different design options for a spoken dialogue system are presented. In addition to the documentation of the outcomes of this evaluation in terms of standard quantitative measures we also present findings from a more q...

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

objectives comparing the effects of spontaneous pushing in the lateral position with the valsalva maneuver during the second stage of labor on maternal and fetal outcomes. methods inclusion criteria in this randomized clinical trial conducted in iran were as follows: nulliparous mothers, live fetus with vertex presentation, gestational age of 37 - 40 weeks, spontaneous labor, and no complicatio...

The purpose of this study was to investigate cortical mechanisms upstream to the corticospinal motor neuron that may be associated with central fatigue and sense of effort during and after a fatigue task. We used two different isometric finger abduction protocols to examine the effects of muscle activation and fatigue the right first dorsal interosseous (FDI) of 12 participants. One protocol wa...

BACKGROUND Within 6 years of a myocardial infarction (MI) more women (35%) than men (18%) will have another MI. Participation in physical activity is one of the most effective methods to reduce cardiac risks; however, few older women participate. One of the most frequently reported barriers to physical activity is fatigue. OBJECTIVES The specific aims of this study were to (1) describe factor...

conclusions the study findings highlight the importance of the mental aspect of fatigue in this working group. these results have possible implications for workers’ health and well-being and for the design of shift work systems, for industrial workers. background shift work is a well-recognized occupational health hazard in both industrialized and industrially developing countries. prolonged wo...
