AN OPTIMAL l / N BACKUP POLICY FOR DATA FLOPPY DISKS UNDER EFFICIENCY BASIS
A word processor has become one of essential devices used in offices. Document files created by using a word processor are generally preserved on a floppy disk 01' floppy disks for referencE's. Nevertheless, the files stored on a floppy disk art' occasionally lost due to human errors. the life of the floppy disk and a failure of hardware devices, which comprise the word processor. This is callp...
متن کاملRecovering Data from Failing Floppy Disks
As floppy disks and other similar media age, they may lose data due to a reduction in the retention of electromagnetic fields over time, mainly due to environmental factors. However, the coding techniques used to write data can be exploited along with the fault mechanisms themselves to successfully read data from failing floppy disks. This paper discusses the problem of recovering data from fai...
متن کاملAn Optimal Model for Medicine Preparation Using Data Mining
Introduction: Lack of financial resources and liquidity are the main problems of hospitals. Pharmacies are one of the sectors that affect the turnover of hospitals and due to lack of forecast for the use and supply of medicines, at the end of the year, encounter over-inventory, large volumes of expired medicines, and sometimes shortage of medicines. Therefore, medicine prediction using availabl...

متن کاملA Method for Recovering Data From Failing Floppy Disks with a Practical Example
As floppy disks and other similar media age, they have a tendency to lose data because of the reduction in retention of electromagnetic fields over time associated with various environmental degradation factors. In attempting to read these disks, the coding techniques used to write them can be exploited along with the proposed fault mechanisms to demonstrate that repetitions of read attempts un...
