— In this paper, a novel quantum-dot cellular automata (QCA) adder design is presented that reduces the number of QCA cells compared to previously reported designs. The proposed one-bit QCA adder structure is based on a new algorithm that requires only three majority gates and two inverters for the QCA addition. By connecting n one-bit QCA adders, we can… (More)
In this paper, we introduce a novel reconfigurable graphene logic based on graphene p-n junctions. In this logic device, switching is accomplished by using co-planar split gates that modulate the properties that are unique to graphene, including ambipolar conduction, electrostatic doping, and angular dependent carrier reflection. In addition, the use of… (More)
This paper introduces the image reconstruction algorithm from Sheffield group and the validity of this algorithm to the Sussex MK4.
The Sussex MK4 electrical impedance mammography (EIM) is an EIT system dedicated to breast cancer detection. The novel electrode configuration with its data acquisition method has significantly enhances the system performance by improving the signal-to-noise ratio (SNR).
