#Drive-by heat mapping In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world.
An onboard control system has software to track the route and manage the cameras. On the software side, computer vision and machine-learning algorithms stitch together the images, extract features,
An additional major advantage is the ability to bring these models on commercial airplanes, whereas real parts of bombs are allowed never.
The training set costs approximately $7, 000 and may be shipped as ordinary luggage on commercial flights.
and our reliance on that convenient, high-energy density resource will likely continue for decades to come, especially in the transportation sector.

This kind of data can be used to ease the flow of urban traffic and optimize retail setups.
which meant that it would not disrupt graphene's electrical transport properties. By not doping the graphene sheet
but simply placing it on the layer of yttrium iron garnet they ensured that graphene's excellent electrical transport properties remained unchanged.

Bicycles and Airplane propellers This is only possible because light has an intrinsic angular momentum, the spin. Similar to a pendulum which can swing in one particular plane
""A simple plane wave has the same polarization everywhere, "says Arno Rauschenbeutel, "but when the intensity of the light changes locally, the polarization changes too."
The rotational plane of the light wave pivots by 90 degrees.""Then, the direction of propagation is perpendicular to the spin, just like a bicycle, moving into a direction

""Our research focuses on understanding the physics of thermal transport on submicron length-scales in the presence of an interface,
"Our study focused on a variety of crystals that have controlled differences in thermal transport properties, such as Si, doped Si,
Wilson and Cahill also studied the effect of interfaces on nanoscale thermal transport.""It's been well known for 75 years that the presence of a boundary adds a thermal boundary resistance to the heat-transfer problem,
but it's always been assumed that this boundary resistance was localized to the interface and independent of the thermal transport properties of the underlying material,"Cahill added."
Stacked compounds are ideal for charge transport since this configuration has the largest charge transport anisotropy.
Charge transport anisotropy is a phenomenon where electrons flow faster along a particular crystallographic direction due to close molecule-molecule interactions.
while maintaining exceptional ability to transport charges. This is achieved thanks to clever nanoengineering of the active layer inside the device.
one can achieve significantly higher charge transport and electricity than had previously been possible using the same materials.
This means that the transport of electric charges occurs with a very little energy loss. Previous studies have reported that there is a percolation threshold for the amount of carbon nanotubes necessary to transport efficiently electric charges in a device.
Then you could unload the remaining cargo at the destination.''However this still requires fine-tuning.

We're looking at a revolution in transportation he says. For Bond the engine represents the beginning of the world's first fully reusable spaceship a new kind of craft that promises to do
The vehicle would have a fuselage reminiscent of the Concorde and take off like a conventional airliner accelerate to Mach 5. 2
and blast out of the atmosphere like a rocket. On the return trip Skylon would touch down on the same runway it launched from.
That price would even undercut the $50 million sum that private spaceflight company Spacex plans to charge to launch cargo on its two-stage Falcon 9 rocket.
which they say could be ready for flight tests in the next four years. Building the craft itself would require a much heftier investment:
They can haul more cargo and more fuel than single-stage craft. Rockets also offer reliability on average only one out of 20 launches fail in part
Spacex CEO Elon musk told an audience at the National Press Club in 2011 that private spaceflights would need to follow a model closer to that of airlines.

When air strikes an engine at five times the speed of sound it can heat up to nearly 2000 degrees Fahrenheit.
If and when the engine passes flight tests one of Reaction engines'plans is to license the technology to a potential partner in the aerospace industry.
It all starts with regular SSTO flights. Very awesome breakthrough on heat exchange. This single breakthrough will ripple through a host of applications.
This saves on the weight of oxygen that would otherwise be needed for the flight through the atmosphere.
Most aircraft are designed to fly with a nose up angle of attack. This way the fuselage generates lift.
Since the engine inlet is extremely sensitive to the direction of airflow at high mach numbers it is angled down 7 degrees
but then they wouldn't have a convenient place for the rear landing gear and having the engines close to the ground makes them easier to service.
4. If LOX is an oxidiser for at least part of the flight where is the tank?
5. If LOX is used for part of the flight its weight needs to be factored in. Not just the weight of liquid hydrogen.

It s based on aircraft carriers which are notoriously challenging to land on. The Navy s own X-47b experimental drone has landed on an aircraft carrier successfully
