The information capacity of a distributed storage system is the amount of source data that can be reliably stored for long durations. Storage nodes fail over time and are replaced, and thus data is erased at an erasure rate. To maintain recoverability of source data, a repairer generates redundant data from data read from nodes, and writes redundant data to nodes, where the repair rate is the r...

this work is focused on synthesis of sio2- cnt hybrides via sol-gel method. homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (cntcooh) with active silicic acid followed by titration to the solution of sodium silicate (na2sio3) under the average temperature condition of 80?c. different ratios of multi-walled carbon nanot...

Background: Blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. Many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. Consequently, damage to erythrocytes by free radicals may occur. So it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

Task Force was created to review and identify standards for CO2 storage capacity estimation. Force has previously issued a Phase I report (in August 2005) which served to document the nature of the problem such as the relationship between assessment scale and the level of detail and resolution of the storage capacity. This report of the Task Force's Phase II activities summarizes the Phase I fi...

the different factors such as harvest time, product handling, temperature and storage duration can be influenced on the different properties of citrus fruits and has considerable economic consequences. therefore a factorial experiment based on completely randomized design with 3 replications was performed to evaluate the effects of harvest times (start of color change, 50% of color change and f...

In this paper, we discuss several aspects of data organization in the framework of a recently developed magnetic bubble memory technology known as a bubble lattice file. A dynamic ordering scheme, different from those implemented in conventional T-I bar bubble memories, is proposed. This ordering is particularly suited for bubble lattices. Some performance figures are included for comparison. I...
