Train car crowding is a key issue resulting in passenger dissatisfaction and degraded transit service. One reason for train car crowding is an uneven distribution of passengers among the train cars which results in overcrowding of certain cars while leaving other cars sparsely occupied. If passengers waiting at a station are informed about the expected crowding levels in the arriving train, they c ...

Driving under the influence of marijuana, the most commonly used illicit drug in the United States is reported to double the risk of crash involvement. As marijuana decriminalization and legalization measures continue to gain acceptance, the potential number of drivers using marijuana could rise dramatically, necessitating new ways for law enforcement to combat the pursuant increase in drug relate ...

In Phase I, Migma Systems propose to develop a robust system for detection of railway track surface cracks. Automated railway inspection is critical for ensuring the safety of public transportation. Rails often break under trains and broken tracks can lead to train derailment. In Phase I, we will make a prototype sensor with low power microprocessor, IR camera, GPS and temperature/humidity sensor ...

The intoxicating effects of marijuana are of public safety concern. With the expected increase in the use of this substance it is important to provide law-enforcement officials with a simple driver test for its detection. Because of the presence of the intoxication agent tetrahydrocannabinol (THC) vapor in the exhaled breath of marijuana users, it is possible to confirm marijuana intoxication via ...

Formaldehyde is a reactive and flammable aldehyde which is well known as one of the harmful volatile organic compounds. A_x000D_ combination of respiratory disease, allergic dermatitis and other ailments so called Sick Building Syndrome (SBS) is associated with chronic exposure to formaldehyde. Therefore, monitoring for formaldehyde is important in residential buildings. In this Phase I_x000D_ dev ...

Methane is the second most prevalent greenhouse gas emitted after carbon dioxide, however, on a pound-to-pound comparison methane has a 25 times greater impact on climate change than carbon dioxide over a 100-year period. Accordingly, the 2014 Climate Action Plan signed by President Obama has directed agencies including the USDA, DOE, and EPA to reduce methane emissions. A significant effort in th ...

Capacitive deionization (CDI) is a robust, energy efficient, and cost effective technology for water desalination. In collaboration with Dr. Satish Kumar and Dr. Costas Tsouris at Georgia Tech, we are developing nanostructured carbon material for effective and economical water and wastewater desalination. Our new approach for CDI is enabled by (1) synthesis of nanostructured high surface area acti ...

Not Available The proposed instrument will assist in the simultaneous chemical and mineralogic analysis of microsamples of soil, rocks and minerals by x-ray fluorescence and x-ray diffraction. The innovations include a compact, low-average power, high-peak power, microfocus x-ray source (tube) that uses a pulsed field emitter cathode (no thermionic emission) to produce a bright, x-ray microspot on ...
