We present experimental measurements and analysis of RF interference between a passive RFID system and a generic frequency hopping communications system in the 902 928 MHz ISM radio band. Interference in both directions is considered, RFID to
This work describes a method to produce inexpensive and field deployable samples that can be used to verify the working condition of trace contraband vapor detectors such as ion mobility spectrometers (IMS). With such instruments, including chemical

A procedure for automated bullet signature identification is described based on topography measurements using confocal microscope and correlations calculation. Automated search and retrieval systems are widely used for comparison of firearms evidence. In
This paper posits the need for comprehensive theories about human behavior in fire evacuations. These would be of value in and of themselves to improve training, education, and future data collection efforts, but would also allow for a complete behavioral
