Mechanical and thermal properties of carbon fiber reinforced composite with silanized graphene as nano-inclusions
(SAGE, 2020-09-02)The use of nanofillers to enhance the properties of fiber reinforced composites is limited due to the adverse effect on mechanical properties caused by agglomeration of these nanofillers in the matrix materials. In this ... -
Algebraic insight on the concomitant motion of 3RPS and 3PRS PKMs
(Springer, 2020-04-21)This study presents an algebraic method to detect, count, and identify concomitant motions of parallel robots at the velocity level. The pose and orientation of moving platform of parallel manipulators (PMs) with f-DOF ... -
Human factors to develop a safety guard model in human-robot interaction
(Springer, 2020-04-21)In this research, a strategy to incorporate an assist-as-needed scheme into human-robot collaboration during an object co-lifting and manipulation task is developed. Surface Electromyography (sEMG) signals from the upper-arm ... -
Aircraft loss-of-control: Real-time adaptive prediction of safe control margins and pilot advisory displays
(Wichita State University, 2020-07)Predictive systems with the ability to warn pilots of impending entry into loss-of-control have the potential to improve safety in flight. Along these lines, the research documented in this dissertation has sought to develop ... -
3D engineered capillary evaporators for enhanced critical heat flux and heat transfer coefficient in pool boiling and vapor chamber
(Wichita State University, 2020-07)A major challenge in pool-boiling heat transfer lies in the limit of the Critical Heat Flux (CHF) and Heat Transfer Coefficient (HTC), which is caused by the poor counterflow of liquid and vapor over a heated surface, ... -
Mechanical testing and evaluation of D3O® material for adequacy of an ergonomic intervention for vibration transmission reduction in aircraft manufacturing
(Wichita State University, 2020-07)Daily exposure to vibrations produced by hand-held percussive vibratory power tools can be detrimental to aircraft manufacturing sheet metal mechanics. ISO (5349-1, 2001b) indicates that symptoms of the hand-arm vibration ... -
Modeling the evolution of open quantum systems
(Wichita State University, 2020-07)The motivation for the research is to find a method to describe the evolution of an open single qubit system since the Schrödinger equation cannot be used. Therefore, to do this, the single qubit is first coupled to another ... -
A mattress contact model for a musculoskeletal simulation of human rolling
(Wichita State University, 2020-07)Limited mobility affects a lot of people, including those who have recently had surgery or major trauma, the geriatric population, and people with disabilities. Many people with limited mobility cannot reposition themselves ... -
The development of heparan sulfate within the glycocalyx
(Wichita State University, 2020-07)A key to protecting vessel health occurs at the interface between circulating blood and endothelial cells. Strategically located at this interface is the endothelial glycocalyx, the first “line of protection” for blood ... -
Planetary gear train microcrack detection using vibration, grayscale images and convolutional neural networks
(Wichita State University, 2020-07)Planetary Gear Trains (PGT) are widely used in many industrial applications from wind turbines to automobile transmissions due to its high power to weight ratio. Since PGT can be subjected to faults and prone to failure ... -
Design and evaluation of a GUI for signal and data analysis of mobile functional near-infrared spectroscopy systems
(Wichita State University, 2020-07)Functional near-infrared spectroscopy (fNIRS) is an emerging neuro-imaging modality that can indicate cortical functionality with good temporal resolution (0.5-1 sec). Unlike fMRI, up to now, there is no standard method ... -
Impact of launch injection errors on orbit-raising of all-electric satellites
(Wichita State University, 2020-07)To mitigate the cost of chemical propulsion satellites, satellite operators are increasing their utilization of all-electric propulsion satellites for orbit-raising missions to geosynchronous equatorial orbit. However, ... -
Superhydrophobic coatings for steel pipeline protection in oil and gas industries: a comprehensive review
(Elsevier, 2020-11)Recently, there have been numerous deadly gas and oil pipeline explosions in the United States, resulting in extensive investigations based on corrosion and aged foundations. Superhydrophobic coatings are being developed ... -
Application of forearm FMG signals in closed loop modality-matched sensory feedback stimulation
(Springer, 2020-08-15)This study is aimed at exploring a technology that can use the human physiological information, such as Force Myography (FMG) signals to provide sensory feedback to prosthetic hand users. This is based on the principle ... -
Fabrication and biological analysis of highly porous PEEK bionanocomposites incorporated with carbon and hydroxyapatite nanoparticles for biological applications
