This paper presents a novel visual servoing strategy for a nonholonomic mobile robot, which is based on a new motion estimation technique. By taking into account the planar motion constraint of mobile robots, the proposed motion estimation technique does not require the estimation and decomposition of the homography or fundamental matrix, and it dose not cause any ambiguity problems. Moreover, the...
In this work a four terminal Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is studied. The jammer relay does not hear the source transmission. It assists the eavesdropper and aims to decrease the achievable secrecy rates. The source, on the other hand, aims to increase the achievable secrecy rates. Assuming Gaussian strategies at the source and the jammer...
We describe a method for filtering object category from a large number of noisy images. This problem is particularly difficult due to the greater variation within object categories and only a few labeled object images available. Our method deals with it by using visual consistency and semi-supervised approach. The images of one category often share some visual consistency so that the most irrelevant...
Through analyzing the control effect of three different controllers, such as PID, fuzzy control and fuzzy-PID, it was proved that fuzzy-PID parameters self-tuning controller can make central air-conditioning system get well dynamic and steady performance, Simulation results showed that the fuzzy-PID method can restrain its time delay,high inertia and non-linearity. Using fuzzy-PID parameters self-tuning...
This paper has studied the frequency band characteristics of the piezoelectric/piezomagnetic layered periodic composites. Both piezoelectric and piezomagnetic materials are assumed to be transversely isotropic. The displacement transfer coefficients of all the scattered waves are calculated by the transfer matrix and the stiffness matrix methods. Numerically calculated results show that the band structures...
