Fluid Contact Angle Assessment to Evaluate Wetting of Dental Materials
(East Carolina University, 2017-04-27)Dental crowns account for a large percentage of restorative dental procedures, but the crown materials have been shown to cause wear on the natural opposing tooth. There is uncertainty regarding which mechanical or chemical ... -
Functional Connectivity Analysis of Visually Evoked ERPs for Mild Cognitive Impairment
(East Carolina University, 2022-04-28)Mild cognitive impairment (MCI) is considered as the early stage of Alzheimer's disease, characterized as mild memory loss. Using electroencephalogram (EEG) data, a novel method of functional connectivity (FC) analysis can ... -
Graph Theoretic analysis of the Human Brain Functional Connectivity Alteration Due to Sleep Restriction
(East Carolina University, 2023-05-03)Sleep plays a vital role in learning and memory consolidation. Several studies used brain models of sleep deprivation (SD) and insomnia to study the association between sleep deficiency and cognitive decline conditions. ... -
Identifying a cross-correlation between heart rate variability and skin conductance using pain intensity on healthy college students
(East Carolina University, 2018-05-18)Chronic pain affects approximately 100 million Americans annually. Heart rate variability and skin conductance have been used separately as measures of pain intensity. Current methods of assessing pain intensity have some ... -
IDENTIFYING A RELATIONSHIP BETWEEN DESIGN CONCEPT REPRESENTATION STYLE AND CONSUMER PRODUCT PREFERENCE
(East Carolina University, 2023-05-03)Product designers are constantly seeking insight into the mind of the consumer in efforts to get a better idea as to what the market demands. Feedback from consumers informs designers on changes that need to be made to a ... -
Identifying Mold Heath Hazards Using Smartphone-based Microscope
(2018-03-28)The current technological development of smartphones makes it possible to use them in identifying environmental health hazards. Based on the known information about mold types and their reproductive routines, economically ... -
Increasing Creative Output by Visually Enhancing Engineering Design Tools
(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 Use of Virtual Reality Headsets for Postural Control Assessment: An Instrument Validation Study
(JMIR Publications, 2020-10-11)Accurately measuring postural sway is an important part of balance assessment and rehabilitation. Although force plates give accurate measurements, their costs and space requirements make their use impractical in many ... -
LOW RESOLUTION ELECTROMAGNETIC TOMOGRAPHY (LORETA) ANALYSIS OF THE BRAINS ELECTROPHYSIOLOGICAL RESPONSE TO EMOTIONAL VISUAL STIMULI UNDER DIFFERING CONDITIONS
(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 ... -
A novel particle filtering method for estimation of pulse pressure variation during spontaneous breathing
(2016-08-11)Background: We describe the first automatic algorithm designed to estimate the pulse pressure variation (PPVPPV) from arterial blood pressure (ABP) signals under spontaneous breathing conditions. While currently there are ... -
OSCILLATING SURGE WAVE ENERGY CONVERTER GEOMETRY OPTIMIZATION FOR DIRECT SEAWATER DESALINATION
(East Carolina University, 2023-05-03)Having a reliable supply of fresh water is a problem that affects nations around the world. Saltwater desalination is one of the best methods for fulfilling this need, but it is an energy-intensive process that is expensive ... -
Passive micromixers for DNA analysis using CFD modelling
(East Carolina University, 2018-07-17)Mixing efficiency is an important issue in the design of micromixers, since effective mixing is required between Deoxyribonucleic acid (DNA) sample and restriction enzyme for a fast digestion process. Mixing is improved ... -
