One technique uses three fiducial markers, while the other two uses eigenvectors of the inertia matrix of the Neuro-Image, to compute the three angles (pitch, yaw and roll) needed to register the test Neuro-Image to the reference Neuro-Image. A rigid body transformation is computed and applied to the test Neuro-Image such that it results aligned to …

Computer Anxiety's Impact On Computer User Documentation, Brenda Y. Moore

Theses

Computer anxiety is the fear or avoidance of the computer and the environment it represents. The anxiety can manifest in all computer users regardless of their experience or complexity of the tasks they must complete. The anxiety can be alleviated on one task, but as technology changes and advances, the user's comfort level is compromised and the anxiety reappears. Understanding computer anxiety as it relates to computer user documentation is a compelling research question. Although there have been many efforts to understand computer anxiety, there has been no clear way for technical communicators to resolve this problem in their approach …

Interpreting Wit, Annmarie Giunta

Theses

Graphic design is everywhere and everyday just about everyone interacts with it on some level. Since some graphic design has evolved into quick "on-the-go" design, the elements used to create a message are being ineffectively used. When designing with the graphic design elements, for the most part, there is still a majority that does not understand the reasoning or meaning in the placement of the elements. The purpose of this thesis is to teach graphic design elements to those who do not understand graphic design. A teaching tool has developed with the evolution of this thesis; this tool is wit. …
