However, because the LUR models were based on ambient air measurement data, they estimated total ambient air pollutant concentrations with contributions from many sources other than local traffic emissions.
To address our first set of research questions, we apply an unsupervised learning tool known as the self-organizing map (SOM) [Pearce, Waller et al. (2014) explain the use of SOMs for ambient air quality classification] to develop categories of days (i.e., multipollutant day types) based on ambient air quality data that reflect how multipollutant combinations vary in time at our study location.
Based on ambient bacterial abundance at the time of sampling, this gene was present in 0.005% of the ambient population.
A few "pure" sound pieces are included, notably one by Jeff Talman based on ambient noise in the museum lobby, along with work that fits into no ready category.
Not only that, the laptop features a multi-touch screen, a backlit keyboard, that auto adjusts based on ambient light, and optional 4G LTE connectivity.
In the interest of giving Palomares veterans what he called "the benefit of the doubt," he said, the Air Force stopped relying in 2013 on the old urine test results and instead assigned all troops who cleaned up the site a "worst-case scenario" dose based on ambient air readings of radiation from the time.
Figure 2 ARMA-P method for estimating the mode shape information based on ambient signals.
That one debuted on the iPad back in 2016, bringing with it an automatic temperature adjustment, based on ambient surroundings.
The site response analysis presented here has been based on ambient vibration observations.
The mode shape properties can be estimated accurately using the ARMA-P method based on ambient data.
