wire-brushing is used for different purposes such as removing metal surfaces oxides, increasing surface brightness, improving fatigue properties and surface activation before coating. the wire-brushing severely scratches and stirs the metals in the surface layers, so that complicated metal flow gives rise to very large amount of plastic strain and increases dislocation density of the surface la...

In this day and age, people not only deal with data but deal with vast amounts of data which needs to be sorted and made sense of. A subset of these people are intelligence analysts who sort through an enormous amount of data that need to be organized to uncover plots and subplots. We are proposing a tool called BABES (Brushing+Linking, Attributes, and Blobs Extension to Storyboard) that will e...

We present a novel feedback technique for tooth brushing. Brushing sounds were manipulated and were found to alter the user’s impression. In our experiment, brushing sounds recorded by a microphone in the toothbrush are manipulated and presented to the users in real-time. We demonstrate that frequency manipulation affects feelings of comfort and accomplishment when sound levels are amplified. W...
