quantum-dot cellular automata (qca) is an emerging and promising technology that provides significant improvements over cmos. recently qca has been advocated as an applicant for implementing reversible circuits. however qca, like other nanotechnologies, suffers from a high fault rate. the main purpose of this paper is to develop a fault tolerant model of qca circuits by redundancy in hardware a...

introduction: several supra spinal areas such as rostral ventrolateral medulla (rvlm) area are involved in basic cardiovascular regulation. the kolliker— fuse nucleus (kf) is located in pons and is heavily connected with rvlm. the cardiovascular effect of kf nucleus has been shown and it is suggested that kf is involved in sympathetic vasomotor tone and basic cardiovascular regulation. therefor...

There is a growing interest in models of reversible computation driven by exciting application areas such as bio-systems and quantum computing. Reversible process algebras RCCS [2] and CCSK [8] were developed and general techniques for reversing other process operators were proposed. The paper shows that the notion of reversibility can bridge the gap between some interleaving models and non-int...

a mathematical model is described and applied for adsorption process of ethyl acetate from supercritical co2 stream on activated carbon particles. this model has the ability of illustrating variation of effluent concentration towards different parameters such as flow rate, temperature and pressure. in this research, a vast area of operational conditions is experienced. mass transfer resistance ...

Standard descriptions of thermodynamically reversible processes attribute contradictory properties to them: they are in equilibrium yet still change their state. Or they are comprised of non-equilibrium states that are so close to equilibrium that the difference does not matter. One cannot have states that both change and no not change at the same time. In place of this internally contradictory...
