contrary to the past approaches, as the transportation speed and the number of vehicles have increased, nowadays, the major roads do not go through the cities and are laid out on the brink with a particular distance instead and linked with the city’s network through a set of connecting roads instead. construction of these connecting roads can have diverse effects on economic, social and cultura...

Beginning in 1992, the Slow The Spread (STS) pilot project was initiated to target gypsy moth (Lymantria dispar L.) spread rate reduction by controlling populations in the transition zone. The project uses intensive monitoring techniques, with pheromone-baited sticky moth traps, to detect low-level populations and target them for eradication. The primary objective of the pilot project was to ev...

This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

A vision-based automatic tracking and observation system installed on an ROV has successfully tracked midwater ocean animals (such as jellyfish) in Monterey Bay, California. This system uses stereo vision to localize the tracking vehicle with respect to the target of interest and closes control loops to maintain the target in the views of the cameras. The vision and control algorithms have been...

One of the main vibration problems of aerospace vehicles with liquid fuel propulsion system is fuel sloshing. This phenomenon is a low frequency vibrational challenge which can affect the motion of the vehicle and degrade the stability of the main control system. In this regards, the motion of the liquid will be very critical when the frequency of the sloshing is very close to the frequencies o...
