متن کاملMatching and Predicting Street Level Images
The paradigm of matching images to a very large dataset has been used for numerous vision tasks and is a powerful one. If the image dataset is large enough, one can expect to find good matches of almost any image to the database, allowing label transfer [3, 15], and image editing or enhancement [6, 11]. Users of this approach will want to know how many images are required, and what features to ...
متن کاملAviation-Related Impacts on Ultrafine Particle Number Concentrations Outside and Inside Residences near an Airport
Jet engine exhaust is a significant source of ultrafine particles and aviation-related emissions can adversely impact air quality over large areas surrounding airports. We investigated outdoor and indoor ultrafine particle number concentrations (PNC) from 16 residences located in two study areas in the greater Boston metropolitan area (MA, USA) for evidence of aviation-related impacts. During w...

1922). In this approach, solution, containing sediment particles, is directly sampled at a given depth and time, Limitations of traditional methods for particle-size analysis warrant and particle concentrations are measured by gravimetric the investigation of new techniques. An alternative method based on the difference between the dielectric constant of soil solids (≈4) and analysis. Because o...
