Using programmed formulas in Excel

A NESTED formula that converted a numerical mark to a letter grade which is used at Deakin to create letter grades of High Distinction, Distinction, Credit, Pass, and Fail is outlined. Spreadsheet programming can handle words as well as formulas and numbers. Spreadsheet programming = well-formed formulas + logic + mathematics operations + learning.

Placement of file replicas in data grid environments

In this paper, we address the problem of file replica placement in Data Grids given a certain traffic pattern. We propose a new file replica placement algorithm and compare its performance with a standard replica placement algorithm using simulation. The results show that file replication improve the performance of the data access but the gains depend on several factors including where the file replicas are located, burstness of the request arrival, packet loses and file sizes.
