This paper presents an adaptive neuro-fuzzy controller ANFIS (Adaptive Neuro-Fuzzy Inference System) for a bilateral teleoperation system based on FPGA (Field Programmable Gate Array). The proposed controller combines the learning capabilities of neural networks with the inference capabilities of fuzzy logic, to adapt with dynamic variations in master and slave robots and to guarantee good prac...

When adaptive arrays are applied to practical problems, the performance degradation of adaptive beamforming algorithms may become even more pronounced than in the ideal case because some of underlying assumptions on the environment, sources, or sensor array can be violated and this may cause a mismatch between the look direction of the beamformer and the actual direction of arrival(DOA) of the ...

8MHzBP filter at -Q+ bandpass 70 MHz filter Abstract: Results from an experimental antenna array that is processed adaptively to cancel external radio-frequency interference are presented. The eight-element array has been tested in a far-field anechoic chamber. The adaptive beamformer rejects sidelobe and main-lobe interference by up to 37 dB. A conventional Fourier beamformer rejects interfere...

.. We have investigated the use of adaptive array antenna techniques to maximize the applied electric field at a tumor site in a target body while simultaneously minimizing or reducing the field at the locations of undesired high-temperature regions, or hot spots. Computer simulations have shown that adaptive nulling can prevent undesired hot spots from occurring during the heating of a deep-se...

The construction of a low-cost and reliable array antenna system is required to facilitate the practical use of the adaptive antenna in the mobile communication field. The array antenna system can be verified by DOA (Direction of Arrival) estimation. This dissertation describes the attempt to achieve a high-precision adaptive antenna and the examination of this device, which suppresses the numb...
