application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

This paper is devoted for designing high speed arithmetic logic unit. All of us know that ALU is a module which can perform arithmetic and logic operations. The reason behind choosing this topic as a research work is that, ALU is the key element of digital processors like as microprocessors, microcontrollers, central processing unit etc. Every digital domain based technology depends upon the op...

Electromagnetic interference can cause disruptions to the functional signal on a wired communication channel. Detecting whether transmitted data has been affected by electromagnetic is an important challenge that needs be addressed. This paper describes advanced design of detector detect in channel, and compares it with previously proposed adder subtractor based A&S detector. The performance bo...

Power consumption and especially leakage power are the main concerns of nano MOSFET technology. On other hand, binary circuits face a huge number interconnection wires, which results in dissipation area. Researchers introduced emerging nanodevices multiple-valued logic (MVL) as two feasible solutions to overcome challenges mentioned above. Carbon nanotube field-effect transistor (CNFET) is one ...

In this paper, we present a high-speed, unified elliptic curve cryptography (ECC) processor for arbitrary Weierstrass curves over GF(p), which to the best of our knowledge, outperforms other similar works in terms execution time. Our approach employs combination schoolbook long and Karatsuba multiplication algorithm point (ECPM) achieve better parallelization while retaining low complexity. har...

the full adders (fas) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. with respect to the mosfet restrictions, its replacement by new devices and technologies is inevitable. qca is one of the accomplishments in nanotechnology nominated as the candidate for mosfet replacement. in this article 4 new layouts are presented fo...

This paper extends the canonical single-period model of voluntary costly disclosure to a dynamic setting with asymmetric information over disclosure costs. I show that dynamic incentives have an ambiguous effect on firms’ disclosure decision and that the cost of disclosure no longer prevents full disclosure by all firms. My main results show that (1) there is a positive inter-temporal connectio...
