Microcalcification detection is an important part of early breast cancer detection. In this paper, we propose a microcalcification detection algorithm using adaptive contrast enhancement in a mammography CAD (computer-aided diagnosis) system. The proposed microcalcification detection algorithm includes two parts. One is adaptive contrast enhancement in which the enhancement filtering parameters...

introduction breast cancer is the second cause of mortality among women. early detection of it can enhance the chance of survival. screening systems such as mammography cannot perfectly differentiate between patients and healthy individuals. computer-aided diagnosis can help physicians make a more accurate diagnosis. materials and methods regarding the importance of separating normal and abnorm...

this paper presents a control model of the hydroforming and the dual hydroforming process of atube. the theoretical part includes calculations to measure the change in tube thickness through thedeveloped process. the hydroforming and the dual hydroforming processes are simulated in thesolidsimulation software and the static and the dynamic simulations are modeled. theobtained results for the t-...
