(Wichita State University, 2019-07)
Antibiotic resistance is one of the most serious threats to human health according to the World Health Organization (WHO). Antibacterial resistance has been around since the development of antibiotics, it is a part of ...
• #### A new multidimensional scaling framework for discovering customer requirements ﻿

(Wichita State University, 2016-12)
Customer feedback analysis provides insights into customer satisfaction and helps improve the quality of services and products. The major issue of concern in analyzing customer feedback is the ability to identify their ...
• #### A noninvasive, electromagnetic, epidermal sensing system for biofluid phenomena detection ﻿

(Wichita State University, 2019-12)
Health-care technologies for non-invasive monitoring of vital parameters like blood pressure and heart rate are widely used due to their capability to function as a point-of-care device. However, most of these devices are ...
• #### A novel approach to identify the difference in kinematic behavior of human model lower extremities with respect to muscle activation during impact crash responses using OpenSim ﻿

(Wichita State University, 2017-12)
The main objective of this thesis is to develop a computational human musculoskeletal model to investigate the change in the kinematic behavior of the model's lower extremities under the influence of activated (active) and ...
• #### A novel finite element for modeling a fastener in a lap joint assembly ﻿

(Wichita State University, 2014-12)
This work documents the development of a novel finite element. This element introduces parameters that allow more accurate modeling for the specific application of mechanically fastened lap joints. The research here bridges ...
• #### A novel machine learning framework for phenotype prediction based on Geome-wide DNA methylation data ﻿

(Wichita State University, 2016-12)
DNA methylation (DNAm) is an epigenetic mechanism used by cells to control gene expression, and identification of DNAm biomarkers can assist in early diagnosis of cancer. Identification of these biomarkers can be done using ...
• #### A novel spoofing detection methodology using acoustics and liveness monitoring system ﻿

(Wichita State University, 2014-12)
Standard networking protocols can be very vulnerable to spoofing attacks when extra precautions are not taken by applications to verify the identity. There are several ways to spoof the facial recognition using photograph, ...
• #### A numerical homogenization approach to characterize in-plane anisotropic hyperelastic responses of a non-metallic honeycomb core ﻿

(Wichita State University, 2020-05)
In this research, a numerical homogenization approach to predict the experimentally observed nonlinear elastic, orthotropic and asymmetric responses of non-metallic honeycomb cores under large in-plane deformations is ...
• #### A numerical representative volume element on the mesoscale for parts manufactured through fused deposition modeling and reinforced with short fibers ﻿

(Wichita State University, 2018-05)
The analysis and certification of parts manufactured through Fused Deposition Modeling and reinforced with short fibers are the main drawback of the emerging technology. The present work builds a framework for the discrete ...
