• #### Understanding spacesuit interaction using a wearable proximity sensing system for suit fit optimization ﻿

(Wichita State University, 2019-05)
There is currently no quantitative method of measuring space suit fit for astronauts after they have put on the spacesuit. The primary concern for spacesuit fit is the hard upper torso (HUT), which is composed of a rigid ...
• #### Understanding spatial constraints for autonomous robotic assembly with neural logic learning ﻿

(Wichita State University, 2021-04-02)
Spatial constraints of objects are one of the key elements that are required in industrial assembly. Robots deployed in conventional assembly lines are based on schema by referring to computer-aided design (CAD) software. ...
• #### Understanding the bias in Deep Learning based gender classification systems ﻿

(Wichita State University, 2021-04-02)
Automated gender classification has important applications in many domains such as demographic research, law enforcement, online advertisements, as well as human computer interface. Research search questioned the fairness ...
• #### Understanding the physics of droplet electrocoalescence in a microfluidic device ﻿

(Wichita State University, 2021-04-02)
This work details a parametric study for merging millimeter sized oil droplets, using an electric field, to simulate a mesoscale version of the microfluidic device. This was done to see if the physics of droplet merging ...
• #### Understanding the prevalence of gestational diabetes in urban and rural communities in Kansas ﻿

(Wichita State University, 2021-04-02)
INTRODUCTION: Gestational diabetes is one of the most common medical conditions women encounter during pregnancy and is the leading cause of maternal morbidity and mortality, perinatal and neonatal morbidity, and long-term ...
• #### Undetectability of bridging faults and validity of stuck-at fault test sets ﻿

(IEEE, 1980-01-01)
The study of bridging faults (or short circuits that occur between conducting paths) has become increasingly important with the advent of LSI technology. To date, only a very few papers have been published on this topic. ...
• #### A unified approach for continuous-time compensator design via a graphical user interface (GUI) ﻿

(Wichita State University. Graduate School., 2007-04-27)
In the field of control theory, compensators are used when a control design does not meet the intended design specifications. Some examples of these design specifications could be percent overshoot (P.O.), settling time ...
