The quantity of gas that passes through the meter is determined by collecting the gas in a large tank and measuring its average temperature and pressure,
However, the process of collecting the gas in large tanks generates temperature gradients (different temperatures in different parts of the tank
and volume of a 300 liter collection tank by measuring which microwave frequencies resonated (formed standing waves) within the evacuated tank.
In a second set of experiments, described in a forthcoming paper, they filled the tank with argon gas
From the frequencies and the pressure, they deduced the mass of the argon in the tank.
Finally, they heated the top of the tank to establish a temperature difference across the gas of 4%of the average gas temperature.

New Technology to Lighten Marinesloads Modern-day warfighters face heavyiterallydds on the battlefield, as they often carry more than 100 pounds of gear,
including body armor, weapons and night-vision technology. Such loads can slow them down, reduce agility and result in fatigue, joint sprains or long-term ailments like arthritis or chronic back problems.
To remedy this, the Office of Naval Research (ONR) has presented the Marine corps with a 3-D computer simulation program that measures equipment weight, distribution and effects on body mechanics and individual warfighter performance.

and is now coordinated by a former army general, Ricardo Toro, who for years managed international humanitarian operations in Haiti.
These micro-drones, which can be deployed from military aircraft at altitudes close to 50,000 feet and still fit in the palm of your hand,
could represent the next big thing in the way wars are waged. Think military infestations rather than military invasions.
The CICADA (which stands for Close in Covert Autonomous Disposable Aircraft) is relatively cheap easy to make and totally disposable.
the U s. Naval Research Laboratory released these micro-drones 57,600 feet in the air, let them free fall 11 miles in the sky,
just as the Black Hornet mini helicopter drones were used by The british Army in Afghanistan to detect Taliban fighting units.
Some of the scenarios outlined by the U s. Naval Research Laboratory include dropping CICADA drones tens of thousands of feet above enemy lines,
they might even be able to pick up the movement of submarines below the water surface.
The fascinating part of the CICADA program is how these micro drones could eventually be used as part of a obotic swarmto overwhelm an adversary.
An enemy may be able to defend against several of these drones, but just try to defend against a giant swarm of them launched out of the back of a plane.
And, in fact, there a growing literature about so-called obotic swarmswhich are essentially drones or bots that can be programmed to behave intelligently during combat.
And best of all, these bots and drones can form warmswithout the need for humans to control them.
In another related experiment, the U s. Naval Research Laboratory showed how a group of 13 warm boatsall of them without requiring a human drone operator could be used to protect a high-value naval vessel.
And it doesn stop there. Imagine giant ircraft carriers in the sky capable of launching whole fleets of mini-drones at one time.
Or, better yet, how about underwater aircraft carriers? As Peter W. Singer, an expert on drones and warfare, pointed out about recent DARPA initiatives,
f you are looking at other places where you might see aircraft carriers, don look up in the air, look under the water.
Yes, that right underwater aircraft carriers for drones. In yet another experiment, the U s. Naval Research Laboratory showed that it was possible to release a drone from a submerged submarine with the robotic drone shot out of a Tomahawk missile tube.
As the drone emerges from the tube, its wings unfold before it speeds off to its destination.
Mind blown. What makes micro aerial vehicles such as the CICADA so attractive of course, is that theye cheap to make
And as more uses are found for these micro-drones, it easy to see the price falling further.
Theye not sophisticated drones that you have to learn how to pilot. You just load them up in a plane
which suggests that there just aren enough drone pilots out there to keep up with the military use of drones.
Cheap, simple, disposable and without the need for a human operator it no wonder, then, that the military is interested
so in the potential applications of these micro CICADA drones. Remember when the future of warfare was bigger bigger missile payloads, bigger tanks and bigger warplanes?
In an era of asymmetric warfare, tiny innovations such as the CICADA are what might be needed to take the fight to the enemy in places such as Iraq and Afghanistan.
Imagine if the U s. military had been able to drop off hundreds of these CICADAS over mountainous areas of Afghanistan
or Pakistan in the search for Osama Bin laden. Forget oots on the ground, nsect wings in the skymight be a better metaphor.
If giant swarms of insect-like drones can save the lives of U s. soldiers abroad,
then let the CICADA infestation begin
