...The purpose of EyeBallGUI is to facilitate the eyeballing of multi-channel biosignals for the purpose of artefact rejection (or any other binary grouping). EyeBallGUI displays a set of time-series signals in a MATLAB Figure window, allowing the user to visually inspect and interact with the data via the mouse and keyboard in order to mark data as bad/rejected. The tool can be used to visualize a wide range of data types to make any kind of binary decision about segments of data. However, the motivation for the tool is to facilitate the visualization of multi-channel EEG data for the purpose of artefact rejection. ...

The problem of Pagerank is a simple one to state: Given a collection of websites, how do we rank them? The primary way of formulating this utilizes a transition matrix which relates how web pages interact with each other. We investigate what the effect of a low rank approximation for the transition matrix has on the power method and an inner-outer iteration for solving the Pagerank problem. The purpose of the low rank approximation is two fold: (1) to reduce memory requirements (2) to decrease computational time. We show that we see an improvement in storage requirements and a decrease in computational time if we discard the time it takes to perform the low rank approximation, however at the sacrifice of accuracy.
