A variety of technological navigation aids all help pilots achieve a smooth and safe landing. Early pilots didn't worry about keeping away from other aircraft and landed in any direction on an open field that gave them the best angle relative to the wind. As traffic grew and more aircraft began to use airports rather than farms or fields, landings became limited to certain directions, and descending aircraft, competing for the same course, were in danger of colliding. The earliest landing aids were people-powered. Flagmen provided aircraft sepa ....etc

the design of a generic virtual instrument used for real-time experimentation purposes at Polytechnic Universityâ„¢s control engineering laboratory in a remote-access environment. These instruments can be freely downloaded and the remote user can access the laboratory facilities from anywhere and anytime. The philosophy behind our Internet-accessed remote laboratory is based on a client/server computer configuration. The server, situated near the experiment, transfers to it the received command signals transmitted by the client. The client ....etc

a fault diagnosis platform for Radar circuit is developed here based on the PXI & GPIB Hybrid Bus and virtual instrument technology. Alongwith it a
fuzzy fault tree reasoning algorithm is also described. The platform has two main parts namely hardware and software. The hardware part again is built-in controller and 3 kind of virtual instruments namely digital storage oscilloscope,
digital multimeter and a spectrum analyzer.a fuzzy fault tree reasoning algorithm is used for constructing the software. an
expert knowledge database containing a ....etc

ABSTRACT
Since man began to build machines for industrial use, and especially since motors have been used to power them, problems of vibration reduction and isolation have engaged engineers. Gradually, as vibration isolation and reduction techniques have become an integral part of machine design, the need for accurate measurement and analysis of mechanical vibration has grown. This n ....etc

WEATHER MONITORING AND INSTRUMENT CONTROL SYSTEM USING MICROCONTROLLER
Synopsis

Throughout time we've been fascinated by the weather “ studying signs of change and making and acting on predictions. Today we can page link modern instruments to computers to reduce human error, automate record keeping and control conditions should limits be crossed.
Many weather conditions may be measured, including temperature, atmospheric pressure, rainfall, humidity, wind speed, wind direction and solar energy. Local weather measurements are extrem ....etc
