Synthetic aperture radar (SAR) is valuable military tool that can generate high-resolution images in any illumination or weather condition. As SAR be used for hostile purposes, it important to develop jamming techniques degrade the quality of images. Jamming performance evaluation (JPE) metrics are evaluate effectiveness systems. Existing JPE using Euclidean distance correlation coefficients, b...

introduction in recent years methods based on radio frequency waves have been used for detecting breast cancer. using theses waves leads to better results in early detection of breast cancer comparing with conventional mammography which has been used during several years. materials and methods in this paper, a new method is introduced for detection of backscattered signals which are received by...

Background: auditory training improves the perception of complex acoustic signals as well as the perception of speech. Aim: to verify if auditory training, through the practice of music, has an influence on the ability to recognize speech in quiet and noisy situations. Method: participants of this study were 55 individuals, with no musical experience (non-musicians) and 45 professional musician...
