Abstract: Networked groups of sensors that detect Chemical, Biological, and Radiological (CBR) threats are being developed to defend cities and military bases. Due to the high cost and maintenance of these sensors, the number of sensors deployed is limited. It is vital for the sensors to be deployed in optimal locations for these sensors to be effectively used to analyze the scope of the threat. A genetic algorithm, along with instantaneous plume prediction capabilities meets these goals. An analyzer's time dependant plumes, upwind danger zone, and sensor capabilities are used to determine the fitness of sensor networks generated by the genetic algorithm.

Abstract: The biosensor comprises a modular biorecognition element and a modular flexible arm element. The biorecognition element and the flexible arm element are each labeled with a signaling element. The flexible arm contains an analog of an analyte of interest that binds with the biorecognition element, bringing the two signaling elements in close proximity, which establishes a baseline fluorescence resonance energy transfer (FRET). When an analyte of interest is provided to the biosensor, the analyte will displace the analyte analog, and with it, the signaling module of the modular flexible arm, causing a measurable change in the FRET signal in a analyte concentration dependent manner. The modularity of different portions of the biosensor allows functional flexibility. The biosensor-operates without additional development reagents, requiring only the presence of analyte or target for function.

Abstract: A nuclear quadrupole resonance (NQR) or nuclear magnetic resonance (NMR) apparatus which includes a probe and a variable impedance spectrometer. The probe emits a signal towards a specimen which causes the specimen to produce a resonance signal. After a recovery period from emitting the signal, the probe receives the resonance signal produced by the specimen. The variable impedance spectrometer is connected to the probe and has a total Q factor therewith. The spectrometer causes the total Q factor during the recovery period to be lower than the total Q factor before and after the recovery period by varying the impedance of the spectrometer, without changing the electrical configuration of the probe.

Abstract: A method and apparatus for bonding a layer of coating material onto a subate with minimal bulk heating of the substrate. A pulsed electron beam generator is used to produce high energy electrons at the beginning of the pulse and a larger number of lower energy electrons at the end of the pulse. A thin sacrificial or ablative layer of an easily-vaporized material such as tin is placed on top the coating. The high energy electrons penetrate through the ablative and coating layers. The ablative layer is heated to a molten state, causing it to vaporize. The ablation process generates a force on the coating layer which drives it into the substrate.

Abstract: A magnetic resonance detection apparatus is provided that is not susceptible to acoustic ringing, and a method is provided for eliminating or canceling acoustic ringing from a detected magnetic resonance signal. Specifically, a composite pulse is utilized that allows for both efficient reduction of acoustic ringing signals and the detection of true NQR signals. The composite pulse can be used in any of the common NQR pulse sequences currently utilized simply via substitution of the original single pulses with the composite pulse. Furthermore, although a preferred application involves the spin-1 nucleus 14N and NQR, the composite pulse will be useful for the NQR of other nuclei such as 35CI and 39K and in NMR applications and involving half-integer quadrupolar nuclei and spin- 1/2 nuclei. In addition, coil ringdown and piezoelectric ringing are also substantially reduced.
