FORMATION OF OPTIMUM HIGH PERFORMANCE ONBOARD INFORMATION MANAGING COMPLEX FOR PROMISING HIGH SPEED HELICOPTER

High speed Radix-4 Booth scheme in CNTFET technology for high performance parallel multipliers

A novel and robust scheme for radix-4 Booth scheme implemented in Carbon Nanotube Field-Effect Transistor (CNTFET) technology has been presented in this paper. The main advantage of the proposed scheme is its improved speed performance compared with previous designs. With the help of modifications applied to the encoder section using Pass Transistor Logic (PTL), the corresponding capacitances o...

Improved performance of subballast stabilized using geocell for high speed train

Rapid urbanization and growing industrial demand in many developing countries has led to frequent congestion of the transport infrastructure. Therefore, the expansion of high-speed rail (HSR) networks is crucial to meet this growing demand. Nevertheless, applying high cyclic stress causes significant lateral spreading and in turn excessive settlements of the track substructure. This problem bec...

Managing for High Performance (October 2008)

Helicopter pilot scan techniques during low-altitude high-speed flight.

INTRODUCTION This study examined pilots' visual scan patterns during a simulated high-speed, low-level flight and how their scan rates related to flight performance. As helicopters become faster and more agile, pilots are expected to navigate at low altitudes while traveling at high speeds. A pilot's ability to interpret information from a combination of visual sources determines not only missi...
