Speed Estimation Using Stereoscopic Effect
2014 Tenth International Conference on Signal-Image Technology and Internet-Based Systems, 2014This work is part of developing a new type of radars which is based on stereoscopic effect obtained by using two cameras. The main work is to develop an algorithm for speed estimation. We begin by detecting motions and tracking vehicles in order to identify the vehicle in the next frame. Stereoscopic pictures allow us to calculate the distance from the

Wind speed estimation based variable speed wind power generation
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002Significant variation of the resource kinetic energy, in the form of wind speed, results in a substantially reduced energy capture in a fixed speed wind turbine. In order to increase the wind energy capture in the turbine, variable speed generation (VSG) strategies have been proposed and implemented.

Multistatic sound speed profile estimation
The Journal of the Acoustical Society of America, 2013Sonar is an indispensable component of harbor security systems. Sound propagation is one of the big problems for coverage estimations, since sound speed profiles are complicated under the complex environment like harbors. A new approach for sound speed profile estimation had been proposed using surface scattering by single sonar for frequent ...

Visual Estimates of Airplane Speed
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1961A comparison of field and laboratory studies shows that the variability of visual estimates of airplane speed made by ground observers increases in direct proportion to the mean estimate in the same manner as does the variability of estimates made for quite different moving objects at close range in the laboratory.

Speed estimation with propagation maps
Neurocomputing, 2006We propose a neural architecture that estimates the speed of motion. The basis is a two-dimensional map made of locally connected integrate-and-fire neurons, that propagates and integrates synaptic input in a dendritic-cable-like manner, but irrespective of any direction. The propagation dynamics of such a map are tuned to filter preferred speeds: slow

Rotor Position and Speed Estimation
2018Abstract The ultimate importance of rotor position and speed information in permanent magnet synchronous (PMS) machines control, and the industry interest to the rotor and speed sensorless systems as a cost-saving and practical alternative to the motor control with mechanical sensors are emphasized.

Traffic speed distributions and estimation
1996One of the fundamental parameters for describing traffic flow is the speed, either of individual vehicles or of the traffic stream. It is of importance in work connected with the theory of traffic flow because of the fundamental connection between speed, flow and concentration when the movement of a traffic stream is being considered.

Runway Exit Speed Estimation Models
2020Increasing air traffic in the U.S.A has led to runway capacity limitations at the airports. Increasing the capacity of the existing runways involves reducing the runway occupancy time of an aircraft landing on a runway. The location of runway exits plays an important role in minimizing the runway occupancy time. Locating an optimal location for an exit
