This thesis develops a peers-to-peers intelligent air conditioner (A/C) controller which integrates the power line carrier technology and the infrared remote control. The intelligent air conditioner controller is used for the remote temperature setting and load control of air conditioner without requesting extra communication line and modification of the control circuit in the A/C unit. With the A/C controller developed the demand response in residential and commercial areas can be achieved effectively by reducing the peak power demand of A/C units. In order to investigate the PLC signal transmission over the low voltage distribution lines, the mathematical model of low voltage distribution system under high carrier signal frequency is derived. The computer simulation is executed to analyze the transmission characteristics of power line carrier signal. The proposed controller can receive the command issued by the demand response control center over the distribution lines with carrier frequency to execute the remote temperature setting of A/C units. Based on the field measurement of energy by air conditioner, it is found that significantly power demand reduction of air conditioner has been resulted by applying the proposed controller for remote temperature setting of air conditioner.

Beginning in March 1999 at Georgia Institute of Technology, the ASACA (Assessment of Spatial Aerosol Composition in Atlanta) program has provided PM₂. ₅ concentration and speciation using particle concentration monitoring in and around metropolitan Atlanta. Since 1999, three of the ASACA sites have collected PM₂. ₅ in an urban setting: Fort McPherson (FT, SW), South Dekalb (SD, SE), and Tucker (TU, NE). In January 2007, TU was retired and Fire Station 8 (FS8, NE) was employed as the new urban site. Starting in 2002, PM₂. ₅ concentrations have also been characterized at a rural site, Fort Yargo (YG). Water-soluble ionic species and carbonaceous species concentrations are collected daily on filters using a three-channel particulate composition monitor (PCM). From 1999 to 2008, average PM₂. ₅ concentrations range from 12.9 µg/m3 at YG to 15.4 µg/m3 at TU. Sulfate and organic matter are the main components of Atlanta PM, contributing around 26% and 31% respectively to PM mass. Overall ASACA data quality increased from around 5 in 1999 to a value of 9 in 2005. Seasonal PM data quality appears to be significantly affected by volatility of secondary aerosol species during warm months because ionic data quality regularly decreases in the summer. PM is more sensitive to total sulfate concentration than nitrate and ammonia year-round.
