21. A Novel Approach on Converting Eye Blink Signals in EEG to Speech with Cross Correlation Technique
Year: 2023, Volume: 23, Number: 2
... code, data acquisition. NeuroSky MindWave device senses the binary input coding method can be used for eye blink to signals from the human brain, filters out extraneous noise speech technology [20-21]. Blinking once could represent a and 50/60 Hz electrical interference [21-22]. So, no "1" and ...

... dimensions of the ripple in the torque produced due to the sudden drop in the ERSRM, it is aimed to obtain maximum efficiency and the torque and the acoustic noise are some disadvantages of this desired torque fast in the developed models. As a result of the motor [5-9]. developed models using the GA and ...
23. A Proposed Signal Reconstruction Algorithm over Bandlimited Channels for Wireless Communications
Year: 2023, Volume: 23, Number: 1
... frequencies that are very bandlimited noiseless and additive white gaussian noise close to zero when compared to its highest frequency ... of the normalized mean square error (NMSE) in noiseless and noisy channels. The proposed research articles that ... and other analog signals proposed scheme in the case of noise-free and AWGN over any bandlimited channel. channels for ...

... SRIM) is a better choice with its robustness of solid rotor is relatively reduced while air cylindrical iron mass rotor that provides a mechanically friction and the related acoustic noise between rotating rotor robust structure. On the contrary, poor electromagnetic and air considerably increase. On the other hand, slitting the properties of solid rotor, ...

... to its average, in the middle of the PWM section as presented at Fig. 2. This method has problems with induced delay in signal path and generated noise in real applications. Other method is to average the signal on its PWM period by using oversampling. This method solves problems of previous but introduces additional delay ...

... and upper limb orientation are tracked with an MPU6050 inertial sensor. Figure 3. Conceptual model of the upper limb assessment test setup Kalman filter is used to remove noise components embedded in the sensor data. The algorithm uses output data 1) Pitch and Roll Estimation from the accelerometer and gyroscope in orientation The accelerometer of the ...

... begins to lose its nonlinear power. On the other hand, if underestimation occurs, the function will lack regularization and the decision boundary will be extremely sensitive to noise values in the training data. Laplacian kernel function (Rbf): The Laplace kernel is Figure 4. Linear SVM Model fully equivalent to the Gaussian kernel ...
