Reversible computing has been studied since Rolf Landauer advanced the argument that has come to be known as Landauer's principle. This principle states that there is no minimum energy dissipation for logic operations in reversible computing, because it is not accompanied by reductions in information entropy. However, until now, no practical reversible logic gates have been demonstrated. One of...

Asynchronous Fine-grain power gated Logic (AFL) which includes Modified Efficient Charge Recovery Logic (M-ECRL) gates to implement the logic function of the stage with a handshake controller which comprises of C-element to handle the control signals with the neighboring stages and provides power to MECRL gate. AFL adopts an partial charge reuse (PCR) mechanism, part of the charge on the output...

Quantum computing offers a promising emerging technology due to the potential theoretical capacity of solving many important problems with exponentially less complexity. Since most of the known quantum algorithms include Boolean components, the design of quantum computers is often conducted by a two-stage approach. In a first step, the Boolean component is realized in reversible logic and then ...

Objective: Different categories are available for estimating of radiation dose. Radioisotopes with the same energy and almost the same physical properties have similar effects. Monte Carlo technique is a computerized method based on mathematical simulation of physical processes. The main purpose of this study is to show that beta particles are not able to penetrate deep into the water. also dif...

We demonstrate the fabrication of sub-100 nm T-Gate structures using a single electron beam lithography exposure and tri-layer resist stack - PMMA/LOR/CSAR. Recent developments in modelling development were used to design process, which each is developed separately optimise resulting structure. By approach proximity correcting for full stack, we able independently vary gate length (50-100 nm) h...

moving towards nanometer scales, quantum-dot cellular automata (qca) technology emerged as a novel solution, which can be a suitable replacement for complementary metal-oxide-semiconductor (cmos) technology. the 3-input majority function and inverter gate are fundamental gates in the qca technology, which all logical functions are produced based on them. like cmos technology, making the basic c...

This study compares the cradle-to-gate total energy and major emissions for the extraction of raw materials, production, and transportation of the common wood building materials from the CORRIM 2004 reports. A life-cycle inventory produced the raw materials, including fuel resources and emission to air, water, and land for glued-laminated timbers, kiln-dried and green softwood lumber, laminated...
