Improving the UNC Passive Aerosol Sampler Model Based on Comparison with Commonly Used Aerosol Sampling Methods
Objectives In an occupational environment, passive sampling could be an alternative to active sampling with pumps for sampling of dust. One passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). It is often analysed by microscopic imaging. Promising results have been shown for particles above 2.5 µm, but indicate large underestimations for PM2.5. The aim of t...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

15 صفحه اولA comparison of two sampling methods for global sensitivity analysis
In most cases, global sensitivity analysis requires sampling a model at a large number of points in the input space (Monte Carlo), which requires a corresponding sample design. In this paper, we investigate the convergence properties of two different quasi-random sampling designs in variancebased sensitivity analysis Sobol’s Quasi-Monte Carlo (LP-tau) approach, and Latin supercube sampling. We ...
متن کاملComparison of the Relative Performance of Active and Passive Aerosol Collection Methods for Biological Detection
The ability to reliably detect hazardous airborne biological materials is an inherently difficult and important problem for Defence (i.e., force protection), national security (i.e., detection of anthropogenic and natural hazards, evaluation of risks for first responders) and for ecological monitoring (i.e., air pollution). There are a multitude of approaches to the problem of biological detect...
