Rene-80 nickel-base superalloy as an alloy for production of the jet turbine blades shows high mechanical properties as well as microstructure stability during the high temperature engine operation. In this research, age hardening heat treatment cycle was done on the as-cast Rene-80 superalloy. In the following, microstructure, elemental analysis of phases and macro-hardness of the alloy before...

The liver is a vital organ in human body, and Liver Tumor is considered to be a fatal disease. The tumors which can occur in Liver are cancerous or non-cancerous. For diagnosis of tumor, detection and demarcation of tumor is the initial step to be performed. After detection of the tumor, its type can be determined by using technique like biopsy, which is an invasive technique. To avoid such an ...

1 Abstract The ability of human beings to retrieve information on the basis of associated cues continues to elicit great interest among researchers. Investigations of how the brain is capable to make such associations from partial information have led to a variety of theoretical neu-ral network models that act as associative memories. Recently, several researchers have had signiicant success in...

In this paper, by means of fuzzy approaches, an accurate method is introduced for edging of color photographs. The difference between our method with other similar methods is the use of a morphological operation to think or thick the obtained edges. In this proposed method, a 3×3 window is dragged on the photo. For each block, 12 point sets will be defined, each including two non-overlapping po...
