Rapid explosive detection is vital to protecting lives as well as significant damage to the property. In the past, there have been a number of methods to identify explosives and prohibit them from being transported across the U.S. borders; for example, imaging and chemical identification. [...]
Tens of thousands of international travelers cross secure U.S. borders on a day to day basis, with just about every one of them carrying some sort of hand baggage. It is the duty of the U.S. Customs and Border Protection (“CBP”) to thoroughly check the [...]
Governments all over the world are joining forces to address the issue of climate change. With the increase in global warming driven by human greenhouse gas emissions and the resulting large-scale shifts in weather patterns, space agencies have also entered the fight to heal the Earth’s climate. […]
The military is, beyond the shadow of a doubt, the most vital asset of any country. A capable military represents a strong nation. As a result, most of the hi-tech innovations are devised while keeping military applications in mind. Unmanned robots are no exception. They, [...]
It is not every day that businesses deal with the problem of receiving counterfeit currency. Be that as it may, this act of forgery — despite its infrequency — cannot be overlooked. It goes without saying that this deliberate attempt to defraud the receiver is fraudulent, and that makes it [...]
Night vision was first used in the military in the 1930s on German tanks. These devices provided much better vision than the naked eye but the original version was expensive and heavy. […]
New and expanding ideas of how we look at things is growing almost at an exponential pace. Engineers, scientists and designers are always looking for ways to see things we’ve never seen before. One piece of this emerging technology is what’s known as Time-of-Flight (ToF) cameras. The easiest way of [...]
Recent studies have shown that a wide variety of such contaminants exist at trace concentrations in all water supplies and in the air. Ultraviolet germicidal irradiation (UVGI) is a method of disinfection that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their [...]
Air quality is an increasing concern in the industrialized world. According to the World Health Organization, (WHO), air pollution causes two million death annually in China, India and Pakistan. Moreover, ‘premature death’ of seven million people worldwide each year is due to the health hazards of air pollution. Several severe [...]
The study of the interaction between matter and electromagnetic radiation is known as spectroscopy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Spectroscopic data is often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency. [...]
