In biological systems, individual phenotypes are typically adopted by multiple genotypes. Examples include protein structure phenotypes, where each structure can be adopted by a myriad individual amino acid sequence genotypes. These genotypes form vast connected 'neutral networks' in genotype space. The size of such neutral networks endows biological systems not only with robustness to genetic ...

Integrated circuits have known a constant evolution in the last decades, with increases in density and speed that followed the rates predicted by Moore's law. The tradeo s in area, speed and power, allowed by the CMOS technology, and its capacity to integrate analog, digital and mixed components, are key features to the dissemination of integrated circuits on the eld of telecommunications. In f...

a new fault tolerant controller (ftc) has been presented in this research by integrating a fault detection and diagnosis (fdd) mechanism in a nonlinear model predictive controller framework. the proposed fdd utilizes a multi-sensor data fusion (msdf) methodology to enhance its reliability and estimation accuracy. an augmented state-vector model is developed to incorporate the occurred sensor fa...

Due to its fault-tolerant gates, the Clifford+T library consisting of Hadamard (denoted by H), T , and CNOT gates has attracted interest in the synthesis of quantum circuits. Since the implementation of T gates is expensive, recent research is aiming at minimizing the use of such gates. It has been shown that T -depth optimizations can be implemented efficiently for circuits consisting only of ...

This paper considers problems of fault{tolerant information diiusion in a network with cost function. We show that the problem of determining the minimumcost necessary to perform fault{ tolerant gossiping among a given set of participants is NP-hard and give approximate (with respect to the cost) fault-tolerant gossiping algorithms. We also analyze the communication time and communication compl...
