    COMPARING THE PREDICTED  ELASTIC  MODULUS RESULTS OF GRANULAR  MATERIAL OF BASE LAYERS OF A FLEXIBLE  PAVEMENTSTRUCTURE FROM FWD TESTING WITH SOME OTHER EXPERIMENTS

    FWD testing are currentlyused and studied worldwide. This is a non-destructivetesting, used to evaluate the load capacity of a pavement structure. Results obtainedfrom experiments are the elastic modulus of pavement structure layers, estimated based on deflectionsurface under a load caused byfalling heavy object.Domestically,several researchers remain skeptical about the authenticity of the results predictedfrom FWD. This study refersto the...

  • Synaptic memristor bridge circuit with pulse width based programable weights in digit character recognition

    Synaptic memristor bridge circuit with pulse width based programable weights in digit character recognition

    Memristor bridge circuit linearly generates synaptic weights in the range [-1; 1]. A long width pulse programs the synaptic weights and a short width pulse computes multiplication results in ANN model. Each digit is sampled by 10 times, forming 5x4 matrix. Thecharacter recognition rate achieves 100% for digits from 1 through 5 . 5%, 10%, and 15% noisy patterns is added to consider the recognition rate. Keywords: Memristor bridge, pattern...

  • New binary memristor crossbar architecture based neural networks for speech recognition

    New binary memristor crossbar architecture based  neural networks for speech recognition

    In this paper, we propose a new binary memristor crossbar architecture based neural networks for speech recognition. The circuit can recognize five vowels. The proposed crossbar is tested by 1,000 speech samples and recognized 94% of the tested samples. We use Monte Carlo simulation to estimate recognitition rate. The percentage variation in memristance is increased from 0% to 15%, the recognition rate is degraded from 94% to 82%.

  • IMAGE SEGMENTATION FOR DETECTION OF BENIGN AND MALIGNANT TUMORS

    IMAGE SEGMENTATION FOR DETECTION OF BENIGN AND MALIGNANT TUMORS

    This paper proposes with the segmentation method to separate brain MRI image for edge detection of tumor structure. In particular, an MRI brain image can be enhanced using unsharp approach before segmentation of the MRI image using the Otsu method. The Otsu allows us to detect a suitable threshold to segment the tumor part from the image. After the threshold detection, the binary image will appear some objects. Therefore, the image will be...
