Sasan Soudi; Bahareh Khaksar Jalali; Hossein Eshghifard

Volume 09, Issue 02 , Spring 2020, Pages 65-68

Abstract
  Using narrow-spectrum energy bandwidth can be effective on image quality. Because while increasing the possibility of processing the attenuation coefficient, it also provides a reduction in the beam hardening artifact. For this purpose, in this paper, energy absorption filters are used by planning absorption ...  Read More

6. Evolutionary QCA Universal and Testable Gate

Reza Sabbaghi-Nadooshan

Volume 09, Issue 02 , Spring 2020, Pages 83-88

Abstract
  Quantum-dot Cellular Automata (QCA) with properties such as high density and low power consumption is a promising technology for VLSI future. But high error rate is a disadvantage of this technology, hence it is necessary to design circuits with testability. In this paper a new universal and testable ...  Read More
