This paper introduces a method for counting vehicle axles in the video sequence appropriate for use in vision-based automatic vehicle classifiers with narrow field of vision. The procedure is simple, robust to wheel detector errors, and computationally efficient due to the use of the fast Hough transform. It provides a self-test for applicability for detection of cases where it is not applicabl...

Axle bearings of railway car bogies are important parts that support the running cars. It is desirable to detect damage axle at an early state. Therefore, autonomous detection system (ADDS) was developed does not require a power supply nor wiring and notifies bearing vehicle. The ADDS utilized anti-vibration rubber with built-in piezoelectric element wireless transmitter; which installed on box...

In this reserach we present path curvature sensing methods for a carlike robot, which can be applied to motion planning and motion control. Toward this goal, we use a steering wheel angle sensor and two encoders on the rear wheels in the robot. We then demonstrate two curvature sensing methods using a steering map and wheel odometry at the rear axle. Finally, experimental results are presented ...

The realization of artificial molecular motors capable of converting energy into mechanical work is a fascinating challenge of nanotechnology and requires reactive systems that can operate away from chemical equilibrium. This article describes the design and construction of a simple, supramolecular ensemble in which light irradiation causes the directional transit of a macrocycle along a nonsym...
