Research ArticleOpen accessEvery word in the titleA Novel Fault-Tolerant Majority Gate Architecture for Robust Operation in QCA-Based Nano CircuitsAmi Patel, Vrushank Shah, Dipti KhurgeQuantum Dot Cellular Automata (QCA) is one of the promising alternatives to the traditional CMOS technologies for next-generation nanocomputing, which can be integrated at a higher density and has a higher possibility of low power consumption. Fabrication defects, environmental noise, and fault tolerance, especially in larger circuits, are challenging for practical implementation of QCA circuits. A new Fault-Tolerant Majority Gate … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Electronic Control Circuits for WSN: Towards a Livestock Tracking and Identification SystemObakeng Maphane, Oduetse Matsebe, Molaletsa NamosheBotswana’s beef sector contributes 0.3% of the total world beef exports, i.e. US$ 42.4 billion as of the year 2013 and her major market is the European Union (EU). Unfortunately, her failure to comply with the frequently changing European Commission (EC) export regulations on livestock tracking and identification means that beef export to this market is sometimes suspended. Research trends … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 4 Oct 2017 · 7,967 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication Specific Integrated Circuits Design and Implementation of Rademacher and Walsh FunctionsA. Abbasi, A. R.M. Alamoud, S. A. AbbasiThe orthogonal functions, specially the Rademacher and Walsh functions are being increasingly used in Digital Signal Processing (DSP). Today’s DSP applications require fast processing time in order to meet the challenges of the real time systems. State-of-the-art implementation technologies are therefore being used.
