Security applications

There are three types of fencing suitable for security applications. In increasing order of security, these are ... 

Future development of affinity biosensors based on spectroscopy of guided waves will be driven by the needs of the consumer. These biosensor technologies hold potential to benefit important fields including pharmaceutical research, medical diagnostics, environmental monitoring, food safety, and security. Applications in these areas will challenge research and development in the field.

The field to be monitored is usually narrow and long in perimeter security applications. Thus, non-uniform deployment may be necessary. He et al. conclude that the sensor nodes generate false alarms at a non-negligible rate [18], and an exponentially weighted moving average on the sensor node is sufficient to eliminate transient alarms. 

Since the early 90s, noninvasive functional brain imaging of humans using NIR methods have been slowly gaining momentum despite existence of more established imaging modailties, such as PET, fMRI, and EEG. Part of the reason as stated previously, is because of its relatively high temporal resolution and its ability to monitor multiple tissue chromophores. The technique has been applied to adult as well as infant studies. NIR method is particularly suited for infant studies as the equipment, at least the CW kind, are minimally restraining, relatively safe, and portable [67]. Most neonatal studies focus on sensory stimulation such as visual, auditory and olfactory stimulations [69] [101] [89] [115] [6] [5], and cerebral disfunction [70, 71]. Our review will focus primarily on adult studies with some emphasis on defense and security applications. 

The chapters in this volume were presented at the July 2005 NATO Advanced Study Institute on Advances in Sensing with Security Applications. The conference was held at the beautiful II Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. Once again we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our six previous ASI s continued at this meeting. 

Schools also like the online submission process because they find it is safe and secure. Applications can t get lost in the mail. As soon as you access an online application, your progress may be tracked, so the school to which you are applying knows when you have begun the process, when you have finished, and when you have submitted the application. For example, the University of Michigan s website asserts that every submitted online application was received by our office last year with the data intact and loaded directly into our student information system, with the... 

All three wedge barrier designs have a high crash rating, thereby allowing them to be employed for higher-security applications. ... 

No excavation is required in the roadway itself to install crash beams. All three crash beam designs possess a low crash rating relative to other types of barriers, such as wedge barriers, and thus they typically are used for lower-security applications. 

Bollards have an intermediate crash rating, which allows them to be utilized for medium-to higher-security applications. Some maintenance is needed to ensure barrier is free to move up and down. 

Ion mobility spectrometry is the most commonly deployed method for ETD devices. Its advantages are compact size and relatively low price. For applications requiring a handheld detector, IMS is an excellent choice. For applications that are more stationary, other alternatives to IMS are often used. Mass spectrometry is recognized for its superior performance with regard to sensitivity and specificity, which translate to lower false-negative and false-positive rates. Active programs are now in place to develop routine MS technology for security applications in airports and other venues. 

Mass spectrometry is often referred to as the gold standard for molecular detection and identification. Traditionally a lab-based research tool, MS is now being developed for automated operation in rugged environments by technically unskilled operators. It is therefore inevitable that MS will find a major role in security applications, particularly where detection accuracy outweighs the requirements for size and cost. In this chapter we compared IMS to MS, but in fact the determining factor regarding which detector to deploy depends on application. When inexpensive, handheld analyzers are required, IMS is the best choice. For stationary applications where compactness is less important then the superior performance of MS offers compelling benefits. 

Solvent dyes are also used in the coloration of any solvent or wax based product, including polishes, cosmetics, crayons, candles, inks, stains and adhesives. They are also in the coloured smokes that are used in outdoor displays, for instance coloured trails from aircraft, and in safety and security applications. 

Phosphorescent pigments are used in security applications, such as the coding of...
