A compact UWB monopole antenna with penta band notched characteristics
A modified rectangular monopole ultra-wideband (UWB) antenna with
penta notched frequency bands is presented. An inverted U shaped and
slanted U-shaped on the radiating patch are inserted to achieve WiMAX and ARN bands rejection respectively, two…

Qualitative assessment of image enhancement algorithms for mammograms based on minimum EDV
Breast cancer is one of the leading reason of death among women.
Nevertheless, medications for this fatal disease are still away of ambitions. Patients (thought to have breast cancer) should go through several advanced medical diagnostic procedures…
