Quantum-dot cellular automata is an interesting computation fabric with many never-seen-before properties. However, no programmable fabric scheme has utilized all these properties effectively. We propose an architecture for a programmable device using molecular QCA which exploits all the specialities of the fabric. The architecture taps the flexibility

The International Journal of Cardiac Imaging, 1997
Excellent agreement between different 'second generation' systems for quantitative coronary arteriography (QCA) has been found in in vitro measurements. To verify the quality and stability of QCA when used in clinical practice, three QCA systems (AWOS, Cardio, and CMS) were used in a representative set of coronary artery lesions.This set consisted of ...

The field-coupled QCA architecture has emerged as a candidate for providing local interconnectivity for nanodevices, and offers the possibility to perform very dense, high speed, and low power computing in an altogether new paradigm. Magnetic interactions between nanomagnets are sufficiently strong to allow room-temperature operation.

The Robust QCA Adder Designs Using Composable QCA Building Blocks
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2007Quantum-dot cellular automata (QCA) is attracting a lot of attention due to its extremely small feature size and ultralow power consumption. Up to now, several adder designs using QCA technology have been proposed. However, it was found that not all of the designs function properly.

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 ...
