Novel Defect Terminolgy Beside Evaluation And Design Fault Tolerant Logic Gates In Quantum-Dot Cellular Automata

Quantum dot Cellular Automata (QCA) is one of the important nano-level technologies for implementation of both combinational and sequential systems. QCA have the potential to achieve low power dissipation and operate high speed at THZ frequencies. However large probability of occurrence fabrication defects in QCA, is a fundamental challenge to use this emerging technology. Because of these vari...

Introducing New Structures for D-Type Latch and Flip-Flop in Quantum-Dot Cellular Automata Technology and its Use in Phase-Frequency Detector, Frequency Divider and Counter Circuits

Quantum-dot cellular automata (QCA) technology is an alternative to overcoming the constraints of CMOS technology. In this paper, a new structure for D-type latch is presented in QCA technology with set and reset terminals. The proposed structure, despite having the set and reset terminals, has only 35 quantum cells, a delay equal to half a cycle of clocks and an occupied area of ​​39204 nm2. T...

Edge Detection Based On Nearest Neighbor Linear Cellular Automata Rules and Fuzzy Rule Based System

 Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...

Improved Frog Leaping Algorithm Using Cellular Learning Automata

In this paper, a new algorithm which is the result of the combination of cellular learning automata and frog leap algorithm (SFLA) is proposed for optimization in continuous, static environments.At the proposed algorithm, each memeplex of frogs is placed in a cell of cellular learning automata. Learning automata in each cell acts as the brain of memeplex, and will determine the strategy of moti...
