Afterwards, everyone tried to type the phrase one time, without the cues or vibrations, on a keyboard.
No one in the study had typed previously on a Braille keyboard or knew the language. The study also didn include screens or visual feedback,
so participants never saw what they typed. They had no indication of their accuracy throughout the study. he only learning they received was guided by the haptic interface,
Their strategy was to enable certain synapses to share hardware circuits. The result was called a device Neurogrid.

such as whether to dedicate each hardware circuit to modeling a single neural element (e g.,, a single synapse) or several (e g.,

With that cheaper hardware and compiler software to make it easy to configure, these neuromorphic systems could find numerous applications.

This suggests an ancient conservation in genetic and neural architectures involved in social information processing that transcends the sensory modalities used from mouse to man.
but computer software and hardware are not like that. They often compute to the same level of accuracy all the time. urdue researchers have developed a range of hardware techniques to demonstrate approximate computing showing a potential for improvements in energy efficiency.

#Ink-jet printing creates soft nanostructures A new way to make nanostructures combines advanced ink-jet printing technology with block copolymers that spontaneously form ultra-fine structures.
Recently developed ultra high-resolution ink jet printing techniques have some potential with demonstrated resolution down to 100-200 nanometers
Combining jet printing with self-assembling block copolymers enabled the engineers to attain the much higher resolution as suggested by lead author Serdar Onses a postdoctoral scientist at Illinois. Onses earned his doctorate at the University of Wisconsin
or spatially placed over a wafer. his invention to use ink-jet printing to deposit different block copolymer films with high spatial resolution over the substrate is highly enabling in terms of device design

It operates much like the ink jet-printers printers office workers use for printing on paper. he idea is flow of materials from small openings except e-jet is a special high-resolution version of ink jet-printers printers that can print features down

##The idea for the printer first came to Kayser a few months earlier. He wanted to find a project in which the sun did more than just power a device.
Markus Kayser s homebuilt 3-D printer created this glass bowl out of heated sand from the Sahara For the printer to work efficiently
the printer uses the concentrated beam of sunlight to slowly trace an object into the sandbox layer by layer.
The printer s motors the electronics, cameras and a laptop all run on batteries charged by the solar panels PRINTING Kayser first designs the object he wants to print in a CAD program.
His computer sends instructions to the printer, which works from the bottom up. After a layer has cooled into glass,
he adds more sand to the sandbox in the center of the machine and flattens it out,
and the printer begins heating the next layer. Kayser s first major piece, a bowl, took about four and a half hours to print.
