A new proposal is given to design a spin half-adder in nano-junction. It well known that at finite voltage net circulating current (known as circular current) appears within mesoscopic ring under asymmetric ring-to-electrode interface configuration. This induces magnetic field the center of ring. We utilize this phenomenon construct half adder. The induced used regulate alignments local free sp...

Implementation of a linear optics quantum multibit half-adder that could show potential scalability is discussed. Parametric down-conversion sources are assumed that are pumped by a mode carrying orbital angular momentum l. A single photon from a pair is prepared by detection of its twin. This preparation of a single photon defines two bits to be summed and the starting carry control bit. This ...

We have constructed a solution-phase array of three deoxyribozyme-based logic gates that behaves as a half-adder. Two deoxyribozymes mimic i(1)ANDNOTi(2) and i(2)ANDNOTi(1) gates that cleave a fluorogenic substrate, reporting through an increase in fluorescence emission at 570 nm. The third deoxyribozyme mimics an i(1)ANDi(2) gate and cleaves the other fluorogenic substrate, reporting through a...

<span lang="EN-US">A new design of binary parallel adder circuit is presented in this paper. The pipeline technique applied to implement a group half (HA) blocks architect the proposed adder. pipelined carry (PCA) method suitable for carrying out desired by using HA circuits XOR and AND gates. reduces critical path delay 27% compared with ripple (RCA) relatively lowers logic gates 55% loo...

The Wallace Multiplier is mainly used in the Arithmetic & Logic Unit (ALU) to perform the scientific computation in processors, controller etc... The existing multiplication technique like booth multiplier, array multiplier etc requires more time in multiplications. Hence Wallace Multiplier has been designed by using the parallel process to reduce the delay. The regular Wallace Multiplier requi...

A fluidic one-bit half-adder is made of five channels which intersect at a junction. Two channels are inputs, two channels are outputs and one channel is the drain. The channels direct fluid from input fragments to output fragments and the streams of fluid interact at the junctions. Binary signals are represented by water droplets introduced in the input channels: presence of a droplet in an in...

One molecule acts as both an AND and an XOR Boolean logic gate that share the same two photonic inputs. The molecule comprises a half-adder, adding two binary digits with only light as inputs and outputs, and consists of three covalently linked photochromic moieties, a spiropyran and two quinoline-derived dihydroindolizines. The AND function is based on the absorption properties of the molecule...
