By doubling transistor density, individual chips get smaller, allowing more of them to be printed on a silicon wafer.
Dr. Sastry says the new batteries, which replace the standard liquid electrolyte and electrodes with solids, have the potential of doubling energy density, enabling smaller and more powerful packs that offer electric cars greater range.
Because leads and contacts on a chip cannot be shrunk as easily as transistors, doubling the density of the latter does not quite halve the price of individual devices.
Thousands of spectators who had planned to line the road that winds across the scree were thus forced to join those lower down, probably doubling the density of the crowd in the 15km from Bédoin to the improvised finish at Chalet Reynard.
The latest rumors suggest that the iPad mini will indeed get a Retina upgrade, doubling pixel density (which will in fact make it even sharper than the Retina iPad 4th generation, thanks to the smaller screen).
Doubling the density of the computational fluids mesh and using a scale adaptive simulation turbulence model increased broadband noise accuracy.
In the US for example it has been found that solely by doubling urban density within metropolitan regions, vehicle kilometres travelled (VKT) can be reduced by up to 25%% if employment locations are also concentrated spatially [12].
They showed that by doubling marker density from 1 N e to 2 N e the accuracy of estimated breeding values increased by 14%.
Even if the Double Density CD-ROM is cheaper, DVD is the format of the future.
The new product is called a Double Density CD-ROM/-R/-RW.
