Hard Drive Command Capture and Sequential Stream Detection
<p>This thesis explores hardware command capture as a viable means of analyzing real world hard drive usage. Hardware command capture provides insight into the IO stack where current tools fail to reach. A software platform is presented which provides trace conversion and analysis capabilities. …

Designing and Implementing Hard Drive Inventory Policies for Enterprise Computing Solutions
… decisions are contextual rather than process driven, making it difficult to understand precisely how inventory level is influenced by its independent variables. The objective of this project is to develop a set of dynamic inventory policies to enable inventory reduction at ISG while …

Modelling tribology of slider and disk in a computer hard drive system
… tribology are increasingly important in computer hard drives as slider flying heights are becoming lower and disk protective coatings thinner to minimise spacing loss and allow higher areal density. Friction, stiction and wear between the slider and disk in a hard drive were studied using …

Cheetah: An Economical Distributed RAM Drive
Current hard drive technology shows a widening gap between the ability to store vast amounts of data and the ability to process. To overcome the problems of this secular trend, we explore the use of available distributed RAM resources to effectively replace a mechanical hard drive. The essential …

Critical Current Enhancement In Magnetic Spin-Transfer Nano-Devices Through Doping With The Rare Earth Terbium
… effects, to the potential benefit of magnetic hard drive read head technology. This enhancement is much stronger at lower temperatures, and we can understand the 1/T temperature dependence observed through the application of established theory from the iron garnets. We also show that terbium …

An Interactive Visualization Model for Analyzing Data Storage System Workloads
<p>The performance of hard disks has become increasingly important as the volume of data storage increases. At the bottom level of large-scale storage networks is the hard disk. Despite the importance of hard drives in a storage network, it is often difficult to analyze the performance of hard …

The implementation of nanoimprint lithography for the fabrication of patterned magnetic media
… a major catalyst in increasing the popularity of hard drives. In 2002, two exabytes of original information was stored on hard drives. This is ten times the amount of all printed material in the world if it were converted to electronic files. To keep up with this demand, the capacity of hard …

Software for efficient file elimination in computer forensics investigations
… forensics analysis process for files on a hard disk drive under investigation. A software tool has been developed to dramatically reduce the number of files that an investigator must individually examine. This tool utilizes the National Institute of Standards and Technology (NIST) National …

Rare earth metal separation with new amide functionalised ionic liquids: understanding species and selectivity
… metals from end-of-life products such as hard-drive magnets is of critical importance particularly in the face of growing demand for consumer goods and other applications. Liquid-liquid extraction is the preferred method of separation utilising organic extractants owing to their …

Monitoring PC Hardware Sounds in Linux Systems Using the Daubechies D4 Wavelet.
… parameters such as voltage, temperature, and hard drive status in order to anticipate possible system failure. However, one modality for PC monitoring that has been underutilized is sound. The application described here uses wavelet theory to analyze sounds produced by PC hard drives during …

Distributed Support Vector Machine Learning
… for example) can be managed on a PC without hard-drive thrashing. Training sets of 10,000 however, simply cannot be managed with PC-based resources. For this reason most SVM implementations must contend with some kind of chunking process to train parts of the data at a time (10 chunks of …
