when structures are subjected to strong ground motion excitations, structural elements may be prone to yielding, and consequently experience significant levels of inelastic behavior. the effects of inelastic behavior on the distribution of peak floor loads are not explicitly accounted for in current seismic code procedures. during recent years, many studies have been conducted to develop new de...

Considerable effort in recent decades has focused on near-storm environment interrogation via model-based planar fields (e.g., Stensrud et al. 1997) and model-based proximity soundings in order to discriminate between nontornadic and significant (> F2) tornado environments for supercells (e.g., Thompson et al. 2003, hereafter T03; Thompson et al. 2007). This emphasis in severe environment discr...

Risk assessments are used to inform decision-making in hazardous systems. The process involves highly technical steps such as quantifying uncertainty and it is typically carried out by subject matter experts with a robust engineering background. also value-loaded selecting the risk acceptance criteria for evaluating risks. In built environment, support performance-based design of late, these ha...

The MYTHEN single-photon-counting silicon microstrip detector has been developed at the Swiss Light Source for time-resolved powder diffraction experiments. An upgraded version of the detector has been installed at the SLS powder diffraction station allowing the acquisition of diffraction patterns over 120 degrees in 2theta in fractions of seconds. Thanks to the outstanding performance of the d...

We hypothesized that the anaerobic power and aerobic power outputs during all-out runs of any common duration between 10 and 150 s would be proportional to the maximum anaerobic (E(an-max)) and aerobic powers (E(aer-max)) available to the individual runner. Seventeen runners who differed in E(an-max) and E(aer-max) (5 sprinters, 5 middle-distance runners, and 7 long distance runners) were teste...

background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...

The damage and strain induced by irradiation of both relaxed and pseudomorphic Ge,Si,-, films on Si(100) with 100 keV 28Si ions at room temperature have been studied by MeV 4He channeling spectrometry and x-ray double-crystal diffractometry. The ion energy was chosen to confine the major damage to the films. The results are compared with experiments for room temprature Si irradiation of Si( 100...

A general framework for probabilistic fatigue damage prognosis using maximum entropy concept is proposed in this paper. The fatigue damage is calculated using a physics-based crack growth model. Due to the stochastic nature of crack growth process, uncertainties arising from the underlying physical model, parameters of the model, and the measurement noise are considered and integrated into this...
