The four-parameter logistic model is often used to describe dose-response functions in many toxicological studies. In this study, under the four-parameter logistic model, optimal designs to estimate the EDp are studied. The EDp is the dose achieving p% of the expected difference between the maximum and the minimum responses. C-optimal design works the best for estimating the EDp, but the best p...

Estimation of collapse performance is primarily conducted through Collapse Fragility Curves (CFC’s). The EDP-based approach is the main scheme for attaining such curves and employs IDA. Obtaining CFC’s from IDA results is tremendously time consuming and computationally demanding. Introduction of more efficient methods of seismic analysis, can potentially improve this issue. The Endurance Time (...

Abstract The process of ground motion selection and scaling is an integral part hazard‐ risk‐consistent seismic demand analysis structures. Due to the lack records that naturally possess high amplitude intensity, research community generally relies on match a target hazard intensity level. factors used are frequently as 10. criticism received in previous studies, extent its has become matter de...

All successful infrastructure products and processes exemplify the collaboration of engineering economics in space time. In their respective domains, two specialized professions optimize supply demand (S / D) energy money. If priorities diverge, structural economic failures result. The various stages a bridge lifecycle transitions between them are examined as vulnerable nodes links where diverg...

The under-representation of women and students of color in the undergraduate engineering population is a persistent and complex issue. The numerous “leaks” in the talent pipeline, along with the multifarious causes of under-representation , lead many institutions, including our own, to take a scattershot approach to recruiting and retaining diverse students in the undergraduate engineering popu...

Abstract This paper focuses on the probabilistic analysis of Intensity Measures ( IM s) and Engineering Demand Parameters EDP in context earthquake-induced ground motions. Several statistical properties, which are desirable s when they used to predict s, have been analysed. Specifically, efficiency, sufficiency steadfastness quantified for a set with respect two s: maximum inter-storey drift ra...

Advances in Intelligent Transportation Systems (ITS) have resulted in the deployment of surveillance systems that automatically collect and store extensive network-wide traffic data. Dynamic Traffic Assignment (DTA) models have also been developed for a variety of dynamic traffic management applications. Such models are designed to estimate and predict the evolution of congestion through detail...

Erythema dyschromicum perstans (EDP) and ashy dermatosis (AD) are pigmentary disorders of unknown etiology. EDP is usually considered to be identical to AD; however, a new clinical classification for EDP was proposed in the recent literature. Herein, we report a typical case of EDP observed in an African-American man. Interestingly, the late skin lesions in this case fit the criteria of AD as w...
