CHARACTERIZATION OF SOLID MODELS PRODUCED BY RAPID PROTOTYPING MACHINES
(2014)Parts produced by 3-D printers were tested to determine the mechanical properties and failure modes. Since 3-D printed parts are built up layer-by-layer, they do not have the same properties in all directions. In order ... -
City of Greenville, North Carolina - Sustainability
(2014)Sustainability has been defined by the Brundtland Comission as "meeting the needs of present generations without compromising the needs of future generations." Seeking to become more sustainable, the City of Greenville, ... -
DESIGN OF A FORCE BIOFEEDBACK TOOTH EXTRACTION EDUCATIONAL DEVICE
(2015)The current jaw model used by students from the East Carolina School of Dental Medicine to practice tooth extractions does not accurately simulate the forces in a real human mouth. Originally multiple alternative designs ... -
DESIGN OF A FORCE BIOFEEDBACK TOOTH EXTRACTION EDUCATIONAL DEVICE
(2015-04)The current jaw model used by students from the East Carolina School of Dental Medicine to practice tooth extractions does not accurately simulate the forces in a real human mouth. Originally multiple alternative designs ... -
Design of an Educational Tool Simulating Tooth Extraction Procedure
(2015-04-23)Dental students need to develop clinical skills in determining the force applied during tooth extractions. A student must practice the procedure many times before attaining the appropriate skill level required for decision ... -
Portable respirators suitable for agricultural workers
(2015-10-13)Portable personal respiratory protection devices include a self-contained head gear member with a chin collar that has a front segment that defines a mouth portion and attaches to a back segment that resides over ears of ... -
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 ... -
Poly(ethylene Oxide)/β-lactoglobulin Electrospun Nanofibers: Chemical Crossliking Assessment and Thymosin-β4 Functionalization
(East Carolina University, 2016-12-13)Using electrospun nanofiber scaffolds have emerged as a technique for tissue engineering (TE) applications. In 2011, Sullivan et al. reported on the process to effectively electrospin and crosslink nanofibers from ... -
Utilizing Brain Activity to Non-Invasively Predict Blood Glucose Levels
(East Carolina University, 2016-12-16)Diabetes Mellitus is a chronic condition that must be routinely self-monitored to prevent life threatening complications, diabetic coma, and to mitigate long-term complications, such as neuropathy and kidney failure. Despite ... -
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 ... -
Development of a Heart Motion Tracking System using Non-invasive Imaging Data
(East Carolina University, 2017-07-18)Cardiac motion can be monitored non-invasively for the assessment of cardiovascular function by using medical imaging systems and motion tracking algorithms. Existing tracking approaches require a priori understanding of ... -
Pulmonary Artery Hemodynamics Using MRI & CFD
(East Carolina University, 2017-07-19)Pulmonary hypertension (PH), as defined by a mean pulmonary arterial pressure (mPAP) greater than 25 mmHg, is a life-threatening chronic disorder of the pulmonary circulation which leads to right ventricle failure and if ... -
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 ... -
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 ... -
A NOVEL ROLE FOR HDL AND D-HDL IN PULMONARY IMMUNITY
(East Carolina University, 2018-07-17)Cardiovascular and pulmonary diseases are leading causes of morbidity and mortality worldwide. Studies report an inverse correlation between levels of serum high-density lipoprotein (HDL) and the severity of cardiovascular ... -
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 ... -
Role of antidepressants in fetal synapse formation in Autism Spectrum Disorders
(East Carolina University, 2018-07-23)Autism is a genetically complex neurodevelopmental disorder in which patients exhibit social deficits in both verbal and non-verbal forms of communication and display restricted and repetitive behaviors. Approximately 1 ... -
