Dynamic systems become more and more widespread in many application fields. This observation highlights the trend that systems are no more considered as running in a static, predefined environment. Evolution has to be taken into account and fault tolerance does not make an exception. When the executive or environmental context has changed, hypothesis or fault model may become outdated or invali...

This chapter describes a study on workflow scheduling with fault tolerance. It starts with an understanding on workflow scheduling and fault tolerance technologies independently. Next, the chapter surveys the related works on the combination field of workflow scheduling and fault tolerance technologies. Generally, these works are classified into six categories corresponding to the six fault tol...

The fracture deformations often result in linear morphological elements (lineaments, valleys) on the surface. In many cases, direction of lineaments and valleys can be well followed by strike geological structural elements. Therefore, conclusions drawn from these directions for regional tectonic processes. Our work aimed to analyse relationship between valley lineament network south-eastern par...

This is a sequel to a previous detailed study of quantum corrections to cosmological correlations. It was found there that except in special cases these corrections depend on the whole history of inflation, not just on the behavior of fields at horizon exit. It is shown here that at least in perturbation theory these corrections can nevertheless not be proportional to positive powers of the Rob...

Cloud computing now a day's become most popular and reliable computing technique for organizations and individuals. In the cloud environments, data availability and backup replication are critical and complex issues in the an efficient fault tolerance policy is the major. Fault tolerance policy is the strategy in action when a fault occurs in the system. Taking backups is the one of the most us...

quantum dot cellular automata (qca) is one of the important nano-level technologies for implementation of both combinational and sequential systems. qca have the potential to achieve low power dissipation and operate high speed at thz frequencies. however large probability of occurrence fabrication defects in qca, is a fundamental challenge to use this emerging technology. because of these vari...

Introduction: Dione (1124 km in diameter) is a mid-sized icy moon of Saturn which shows a wide range in tectonic features across its surface revealing an intense geologic history. With the two highly evolved satellites Enceladus und Titan, Dione forms a set of three satellites whose surfaces have been shaped by tectonic activity on a global, not only on regional scale. Tectonic forms on Dione w...

The Cingoli arcuate anticline is part of the Apennines fold-thrust belt in Italy. The anticline nvolves sedimentary carbonate strata generally affected by syn-thrusting contractional tructures such as bed-normal pressure solution seams, folds, and reverse faults. An xception is constituted by an outcrop in the anticline hinge, where sub-horizontal arbonate and chert beds are affected by joints ...
