Seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to a variety of parameters affecting the occurrence of an earthquake. Uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rational way. Using fuzzy method makes it possible to allow for uncertainties to be considered. Fuzzy inference system,...

Introduction: Parallel imaging methods require calibration to coil sensitivities. The autocalibration approach acquires the calibration data along with the normal data acquisition while sampling the full k-space center with a certain number autocalibration lines Nacs [1]. Thus, the net acceleration of such an experiment depends on the undersampling factor R, the number of autocalibration lines ...

In this paper, the probable range of the horizontal component of peak ground acceleration (PGA) is predicted as a function of focal depth, earthquake magnitude and epicentral distance, using artificial neural network (ANN). Three different ANN architectures (namely Feed Forward, Back Propagation and Radial Bias Networks) are used to develop the model. The three models are then compared, to deci...

This study was conducted to compare the performance of three different spatial analysis models: Inverse Distance Weighted (IDW), Ordinary Kriging,­­ and Regularized Spline interpolation technique determine best fit model representing Peak Ground Acceleration (PGA) in West Java Province, Indonesia. The models are commonly used visualization, but have calculation methods. calculations were perfor...

The processes responsible for braking fast and accurate elbow movements were studied in the monkey. The movements studied were made over different amplitudes and against different inertias . All were made to the same end position. Only fast movements that showed the typical biphasic or triphasic pattern of activity in agonists and antagonists were analysed in detail. For movements made over dif...
