Fault-tolerant composite Householder reflection

Principles of Multi-Level Reflection for Fault Tolerant Architectures

This paper presents the principles of multi-level reflection as an enabling technology for the design and implementation of adaptive fault tolerant systems. By exhibiting the structural and behavioral aspects of a software component, the reflection paradigm enables the design and implementation of appropriate non-functional mechanisms at a meta-level. The separation of concerns provided by refl...

Fault tolerant decentralized H∞ control for symmetric composite systems

Fault Tolerant Decentralized Control for Symmetric Composite Systems

This note discusses a class of large-scale systems composed of symmetrically interconnected identical subsystems. We consider the decentralized H1 control design problem and study the fault tolerance of the resulting system. By exploiting the special structure of the systems, a sufficient condition for the existence of a decentralized H1 controller is derived. Moreover, for the nominal case as ...

A New Design of Fault Tolerant Comparator

In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...

Evolutionary QCA Fault-Tolerant Reversible Full Adder

Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...
