The objective of this paper is to simulate and Predict suspended solid removal efficiency in multimedia filter depend on experimental work for (43) case studies. The experimental work was carried out on pilot unit by changing each one of the input parameter and get results for each change. The suspended solid removal efficiency obtained from laboratory was used as target function in ANN while the...
Spectrum sensing is one of the core techniques in the cognitive radio network. In this paper, the cyclostationary feature detection for OFDM signals and the MAC-layer sensing-period adaptation algorithm are presented. Exact analytical expressions for spectral correlation function (SCF) are derived applying cyclostationarity fundamentals, and the simulation results demonstrate that the presence of...
Diffusion tensor-MRI (DTI) White matter fiber tracking traces white matter fibber bundle and its image according to the diffusion of water molecular in the white matter. This paper uses structure information of fiber bundle and DTI information in current voxel to estimate the probability density function of the tracking direction to the next voxel. This algorithm is under the framework of Bayesian...
A back propagation algorithm is a supervised learning algorithm applied to train a neural network off line. This paper introduces a modified learning algorithm. The training algorithm, which is composed of a temporal difference (TD) method and a dynamic BP algorithm (DBP), can train an Elman network online. A gradient descent momentum and adaptive learning rate algorithm is applied to the TD-DBP algorithm...
This paper represents a method of Content Based Image Retrieval (CBIR) which uses multi-wavelet transform to improve the shape and texture feature extraction and decrease the operand. The theoretical analysis is represented first and the numerical verification and experimental validation using real CT image is showed behind. Both the theoretical analysis and the numerical and experimental results...
