Abstract-Recovery procedures involving time redundancy in the form of instruction retries and program rollbacks have proved to be very effective against transient failures in computer systems. A class of such recovery procedures is presented and analyzed here, and the parameters of each procedure

The design of multiple computer systems and computer networks poses some interesting new problems and shows some older problems in the light of a new context. We are interested in the problems which are related to the design of communication protocols and error recovery procedures. In the design

for some ρ> 0. In short, f can be recovered exactly by solving a simple convex optimization problem (which one can recast as a linear program). In addition, numerical experiments suggest that this recovery procedure works unreasonably well; f is recovered exactly even in situations where a significant

Cluster analysis is the automated search for groups of related observations in a data set. Most clustering done in practice is based largely on heuristic but intuitively reasonable procedures and most clustering methods available in commercial software are also of this type. However

have been exposed to intense irradiation (proton, neutron and gamma), to humid air, to standard black varnish (used to paint the inner surface of RICH detectors), and to C 4 F 10 and CO 2 gases. The optical properties of the aerogel have been monitored during these tests and, when required, recovery

A set of definitions common to all certification and test procedures is in:

than rated cycle-life. Incomplete battery recharge introduces battery degradation mechanisms such as electrolyte stratification, gas bubble entrapment, excessive sulfation, and degradation of the positive active mass. Recovery of the PV battery after extended periods in a deficit charge condition may

Insolvency and debt recovery procedures are as crucial to a well-performing financial sector as credit provision itself. They are even more important in Africa, where attempts are underway to create fully-fledged financial markets. For the financial system to be credible, creditors must be ensured

Subject area: Quality/Test Procedures Several recovery procedures for asphalt emulsion residue have been used over the years, but there is no one procedure that has been universally accepted. In this study three recovery methods are used to obtain the residue of the emulsified asphalt: 1
