premature ventricular contraction (pvc) is one of the common cardiac arrhythmias. the occurrence of pvc is dangerous in people who have recently undergone heart. a pvc beat can easily be diagnosed by a doctor based on the shape of the electrocardiogram signal. but in automatic detection, extracting several important features from each beat is required. in this paper, a method for automatic dete...

Multi-beam echo sounders (MBESs) are characterized by the high resolution and density of sounding data. The processing MBES bathymetry data is special interest currently in marine surveying. Combined Uncertainty Bathymetry Estimator (CUBE) surface filtering main MBES-processing algorithms for outliers. These involve five adjustable parameters; however, few studies have looked at parameter optim...

Formation micro imager (FMI) can directly reflect changes of wall stratums and rock structures. Conventionally, FMI images mainly are analyzed with manual processing, which is extremely inefficient and incurs a heavy workload for experts. Iranian reservoirs are mainly carbonate reservoirs, in which the fractures have an important effect on permeability and petroleum production. In this paper, a...
