In write-once memory (e.g., Flash), a cell’s level can only be raised, and erasure is only in bulk. The total number of erasures (endurance) is limited, and drops sharply with technology shrinkage and with cell-capacity increase. The normalized write capacity (ratio of total amount of data that can be written to storage capacity) drops similarly. Various coding schemes enable overwrites at the ...

With the rise of portal sites for image-file download of musical scores, the electronic distribution of musical scores, an activity in progress of 15 years, has attracted increased attention. We describe several data models for score distribution and emphasize the one used in the MuseData archive of musical data (1984–).

1. Introduction Analysis of variance is used to test for the real treatment differences. When the null hypothesis that all the treatment means are equal is not rejected, it may seem that no further questions need to be asked. However, in some experimental situations, it may be an oversimplification of the problem. For example, consider an experiment in rice weed control with 15 treatments viz. ...
