CLUSTER ANALYSIS OF THE ORGANIC PEAKS IN BULK MASS SPECTRA OBTAINED DURING THE 2002 NEW ENGLAND AIR QUALITY STUDY WITH AN AERODYNE AEROSOL MASS SPECTROMETER

Cluster Analysis of the Organic Peaks in Bulk Mass Spectra Obtained During the 2002 New England Air Quality Study with an Aerodyne Aerosol Mass Spectrometer

We applied hierarchical cluster analysis to an Aerodyne aerosol mass spectrometer (AMS) bulk mass spectral dataset collected aboard the NOAA research vessel R.H.Brown during the 2002 New England Air Quality Study off the east coast of the United States.Emphasizing the organic peaks, the cluster analysis yielded a series of categories that are disti

On Over-the-Air Testing for Devices With Directional Antennas

This paper investigates the impact of devices under test (DUTs) with directional antennas on the recreated channel in the over-the-air (OTA) testing for massive multiple-input multiple-output (MIMO) devices using prefaded signal Bird Cages synthesis (PFS) technique.Assuming the uplink in real radio environments, the directional receiver (Rx) antenn
