Polarization ellipse and Stokes parameters in geometric algebra
In this paper, we use geometric algebra to describe the polarization ellipse and Stokes parameters. We show that a solution to Maxwell’s equation is a product of a complex basis vector in Jackson and a linear combination of plane wave functions. We convert...

Particulate Matter Characterization in Manila Observatory
Particulate matter (PM) samples were collected from March to June 2007 on filters using a multi-stage filter setup. Each event generated a sample from fine (2.5 μm and 10 μm (> PM10) size fractions. The samples were analyzed for gravimetric and ionic content....
Identification of Ambient Particulate Matter Source Direction Using The Conditional Probability Function
This study uses the Conditional Probability Function to determine directions associated with high values of receptor model-generated source contributions at the Manila Observatory (MO). Wind measurements and 24-hour average fine and coarse fraction concentrations measured from 2005 to 2007 were used. Results for...
