Increasing Creative Output by Visually Enhancing Engineering Design Tools
Harr, David D (East Carolina University, 2022-05-02)Innovation does not come about by random chance but is intentionally cultivated by the efforts of a designer. Many strategies exist for approaching design, ranging from the instinctual and intuitive to the more technical ... -
Investigating the Performance of the Visual Oddball Paradigm in the Context of Facial Recognition
Abdelfattah, Basel A (East Carolina University, 2021-06-03)The sequential visual oddball paradigm is a technique that is often used to elicit various components of cognitive event related potentials (ERPs). These components may serve as reliable biomarkers for neurodegenerative ... -
LOW RESOLUTION ELECTROMAGNETIC TOMOGRAPHY (LORETA) ANALYSIS OF THE BRAINS ELECTROPHYSIOLOGICAL RESPONSE TO EMOTIONAL VISUAL STIMULI UNDER DIFFERING CONDITIONS
Cadmus, Matthew S (East Carolina University, 2016-07-21)Current methods of diagnosing and monitoring stress include: observing changes in the severity of existing symptoms, the development of new symptoms, hormone level tests, and stress self-assessment surveys. Self-assessment ... -
LOW-COST PHOTOGRAMMETRY SYSTEM FOR GEOREFERENCED STRUCTURE FROM MOTION
Hill, Nicholas Benjamin (East Carolina University, 2022-07-21)Photogrammetry has become increasingly available as a tool for re-constructing the 3D model of real-world objects and terrain, which is referred to as the structure from motion (SFM) solution. The re-constructed model has ... -
