For the past six years Defence R&D Canada – Valcartier has been developing a method for the passive remote sensing of chemical vapours by differential Fourier-transform infrared (FTIR) radiometry. The originality of the method lies in the use of a double-input beam FTIR spectrometer (CATSI) optimized for optical subtraction. This configuration automatically reduces the clutter-to-signal ratio a...

Building on the successful application in the laboratory of PLOT-cryoadsorption as a means of collecting vapor (or headspace) samples for chromatographic analysis, in this paper a field portable apparatus is introduced. This device fits inside of a briefcase (aluminum tool carrier), and can be easily transported by vehicle or by air. The portable apparatus functions entirely on compressed air, ...

High pressure water jets are increasingly being used for cleaning surfaces on an industrial basis. In many instances the use of high pressure water, in such applications as car cleaning, is carried out in combination with mechanical brushes. However, there are many instances, particularly in self service units and where large industrial vehicles, which do not fit into a standard carwash, are cl...

This research examines the ability of current physics-based models to predict magnetopause location. We use Run-On-Request capabilities at Community Coordinated Modeling Center NASA GSFC with 4 magnetohydrodynamic (MHD) models. The position prediction and response time solar wind changes is then compared extreme conditions where crossing geosynchronous orbit have been observed by Geostationary ...

The detection of concealed targets beneath a person’s clothing from standoff distance is an important task for protection and the security of a person in a crowded place like shopping malls, airports and playground stadium, etc. The detection capability of the concealed weapon depends on a lot of factors likes, a collection of back scattered data, dielectric property and a thickness of covering...
