(Wichita State University, 2020-12)
The segmental defect fractures in bone can result from various types of causes such as primary injury, fracture, developmental deformities, after the debridement of bone in osteomyelitis, or resection of bone tumor. These ...
• #### Implementation and evaluation of curved layer fused deposition modeling ﻿

(Wichita State University, 2020-12)
Fused Deposition Modeling (FDM) is an extrusion based additive manufactur- ing (AM) process in which thermoplastic material is extruded through a nozzle. The nozzle deposits material along a two-dimensional path to create ...
• #### Acoustic evaluation of the bell 699 rotor on the tiltrotor test rig in the national full-scale aerodynamics complex 40- by 80- foot wind tunnel ﻿

(Wichita State University, 2020-12)
Aircraft noise is a growing problem in the air travel industry [1]. Urban air mobility (UAM) is a new movement to use rotorcraft to fly in and between large cities to alleviate ground traffic congestion [2]. Aircraft noise ...
• #### Initiating object handover in human-robot collaboration using a multi-modal wearable and deep learning visual system ﻿

(Wichita State University, 2020-12)
Hybrid robotic systems involving humans and machines working together are becoming a fundamental way of human life from things such as home automation, cell phones, to grocery store pickups, humans are working with machines ...
• #### Occupant injury assessment in an emergency landing condition for a vertical take-off and landing aircraft ﻿

(Wichita State University, 2020-12)
In the next few years, the aeronautical industry is poised to change in a way it has not for decades. There has been a rising interest in deploying Vertical Take-Off and Landing (VTOL) aircraft to serve on-demand ...
• #### Writing self-efficacy and linguistic diversity of first-year composition students: An exploratory study ﻿

(Wichita State University, 2020-12)
This study investigates the potential relationship between student writing self-efficacy and marginalized linguistic identities. A total of sixty-nine first-year composition students across two semesters responded to ...
• #### Characterization of the in-plane homogenized mechanical properties of a hexagonal honeycomb core ﻿

(Wichita State University, 2020-12)
