The limits and difficulties looked by CMOS innovation in the nano system has prompted exploration of other potential advancements which can work with same functionalities anyway lower power scattering higher speed. One such technology is Quantum dot Cellular Automata (QCA). In this paper, QCA explored to design authentication system. This paper first presents basic operating principle a Fingerp...

Most of Exclusive-OR(XOR) logic gates on quantum-dot cellular automata(QCA) is based on configuration of 2-input, and they are hardly to be scalable and exists unbearable noise because they are only focused on decrease of latency and space. In this paper, we propose how to make a scalable logic using a wire crossing technique, and give examples of two expanded XOR gate using typical logic gates...

We propose a threshold-logic gate device consisting of subthreshold MOSFET circuits. The device performs threshold-logic operation, using a technique of current addition and subtraction. To examine the operation of the device, we designed sample subsystems, adders, based on majority logic and confirmed their operation by computer simulation. The device has a simple structure and operates at low...

On the basis of modularization of an optical parallel array logic system (OPALS), a new concept of an optical digital computer is considered. The OPALS is a parallel digital optical computing system using optical array logic capable of executing parallel neighborhood logical operations, or cellular logic. Modularizing functional elements in the OPALS, stability, reliability, and flexibility of ...

Quantum-dot Cellular Automata (QCA) is a promising, emerging nanotechnology based on single electron effects in quantum dots and molecules. While many logic implementations based on QCA devices have been proposed in literature [6, 7, 8], the inherent cellular structure of QCA cells make it a natural candidate for Cellular Automata (CA) implementation. CA offers regularity and modularity to the ...

specific and non- specific cellular immune responses were studied in 20 amoebiasis cases and 10 controls. all the study cases and controls were indians living in varanasi, india. ten amoebic liver abscess cases were patients admitted to university hospital. ten non-invasive intestinal amoebiasis cases constituted the second study group. non-specific immune responses were studied using e-rosette...

We aim to search for cellular automata candidates using an automatic system for the demonstration of collision-based universality. Some of these candidates are able to simulate Turing machines in their space-time dynamics using gliders and glider guns. In this paper, we present an evolutionary algorithm that searches for the simulation of a logic gate by cellular automata. Different parameters ...
