Q UANTITATIVE coronary angiography (QCA) has had a tremendous impact in the field of interventional cardiology. Because of its superior accuracy and objectivity, QCA has supplanted visual and hand-held caliper assessments of coronary arteriograms and has improved interobserver and intraobserver variability.

QCA Circuits for Robust Coplanar Crossing
Journal of Electronic Testing, 2007In this paper, different circuits of Quantum-dot Cellular Automata (QCA) are proposed for the so-called coplanar crossing. Coplanar crossing is one of the most interesting features of QCA because it allows for mono-layered interconnected circuits, whereas CMOS technology needs different levels of metalization.

A QCA which uses only binary-value crisp-set data is referred to as a crisp-set QCA (csQCA). In this chapter, the findings of Krook’s (2010) csQCA study on women’s representation in national parliaments are replicated. We first show how to calibrate crisp sets from categorical and continuous base variables, using both external criteria as suggested by ...

Conservative QCA Gate (CQCA) for Designing Concurrently Testable Molecular QCA Circuits
2009 22nd International Conference on VLSI Design, 2009Nanocircuits based on molecular QCA are prone to high error rates. In this paper, we present a novel conservative logic gate termed 'CQCA' (conservative QCA) to design concurrently testable circuits for molecular QCA. In conservative logic gates, there would be an equal number of 1s in the output as there would be on the input.

Quantum dot Cellular Automata (QCA) is an emerging nanotechnology paradigm that is currently being investigated as a possible CMOS substitute. It offers higher speed and lower area and power consumption than CMOS transistors. However, due to its intrinsic pipelined nature, QCA circuits suffer from serious throughput reductions due to feedback signals ...

This section explains how to perform QCA using fuzzy sets, commonly referred to as fsQCA. Since the publication of Ragin (2000), fsQCA has become increasingly popular because continuous base variables need not be dichotomized. After a short theoretical introduction to the concept of fuzzy-set calibration, we introduce the two most popular calibration ...

Quad Countries Algorithm (QCA)
2012This paper introduces an improved evolutionary algorithm based ontheImperialist Competitive Algorithm (ICA), called Quad Countries Algorithm (QCA). The Imperialist Competitive Algorithm is inspired by socio-political process of imperialistic competition in the real world and has shown its reliable performance in optimization problems.

In this chapter, we present design and implementation of iterative computational unit such as binary divider using QCA. Different types of dividers are introduced. Specifically, non-restoring divider is discussed that realized by iterative cellular arrays for parallel divisions. Performance metrics of different existing dividers are analyzed.
