Design and Testing of a Piezoelectric Intramedullary Nail
(University of Kansas, 2020-05-31)The Food and Drug Administration (FDA) defines non-union as a fracture that has not fully healed within 9 months and has not shown further signs of healing after 3 months (1). There are three categories in which diaphyseal ... -
A Novel Fully 3D Modeling of Two-Phase Fluid Flow in Fractured-Vuggy Carbonate Formations Using the Transient Brinkman Equation Coupled with the Second-order Gradient Rock Mechanics Equation Including Porosity Evolution
(University of Kansas, 2020-05-31)Describing the fluid flow behavior in heterogeneous carbonate formations is a challenging task due to the existence of natural fractures and vugs. The fractures and vugs are not porous regions; hence, the fluid flow in ... -
Towards the Understanding of Private Content – Content-based Privacy Assessment and Protection in Social Networks
(University of Kansas, 2020-05-31)In the wake of the Facebook data breach scandal, users begin to realize how vulnerable their per-sonal data is and how blindly they trust the online social networks (OSNs) by giving them an inordinate amount of private ... -
Evaluation of Recycled Aggregate Base Courses Stabilized by Geosynthetics
(University of Kansas, 2020-05-31)Both unpaved roads and pavement sustainability are dependent upon base course performance and longevity. With the depletion of natural resources and limited funding for necessary pavement rehabilitation, alternative aggregate ... -
Defending Against Typosquatting Attacks in Programming Language-Based Package Repositories
(University of Kansas, 2020-05-31)Program size and complexity have dramatically increased over time. To reduce their workload, developers began to utilize package managers. These packages managers allow third-party functionality, contained in units called ... -
Optimization-based Methods in High-Order Mesh Generation and Untangling
(University of Kansas, 2020-05-31)High-order numerical methods for solving PDEs have the potential to deliver higher solution accuracy at a lower cost than their low-order counterparts. To fully leverage these high-order computational methods, they must ... -
Learning and Evolving Flight Controller for Fixed-Wing Unmanned Aerial Systems
(University of Kansas, 2020-05-31)Artificial intelligence has been called the fourth wave of industrialization following steam power, electricity, and computation. The field of aerospace engineering has been significantly impacted by this revolution, ... -
Optical Limiting via Plasmonic Parametric Absorbers
(University of Kansas, 2020-05-31)Optical sensors are increasingly prevalent devices whose costs tend to increase with their sensitivity. A hike in sensitivity is typically associated with fragility, rendering expensive devices vulnerable to threats of ... -
Comparison of conventional activated sludge and aerobic granular sludge reactors for microplastics removal during municipal wastewater treatment
(University of Kansas, 2020-05-31)The objective of this study was to investigate the performance of the conventional activated sludge (CAS) process and the relatively new biofilm process, aerobic granular sludge (AGS) for microplastics removal. In addition, ... -
The Use of Sample Entropy and Fuzzy Sample Entropy to Analyze Somatosensory Deficit in the COP of Quiet Standing
(University of Kansas, 2020-05-31)The long-term objective of this research is to improve the current methods of postural sway analysis by optimizing the performance of entropy, a nonlinear parameter estimating predictability, and verifying its sensitivity ... -
Network Resilience Architecture and Analysis for Smart Homes
(University of Kansas, 2020-05-31)The Internet of Things (IoT) is evolving rapidly to every aspect of human life including, healthcare, homes, cities, and driverless vehicles that makes humans more dependent on the Internet and related infrastructure. While ... -
Multicopter Dynamics in Small Uninhabited Aerial Systems
(University of Kansas, 2019-12-31)Quadcopters and other multicopters were one of the first considered vertical take-off and landing vehicle configurations for heavier than air transport in the early 20th century. After the success of Oehmichen’s No. 2 ... -
Optimization of Operating Conditions of a Mixed Liquor Fermenter for Enhanced Biological Phosphorus Removal
(University of Kansas, 2020-05-31)Enhanced biological phosphorus removal (EBPR) has been used for the past 40 years in municipal wastewater treatment to meet declining effluent total phosphorus (TP) limits. While primary fermentation is not new to EBPR, ... -
Leading the Charge in Bone Healing: Design of Compliant Layer Adaptive Composite Stacks for Electrical Stimulation in Orthopedic Implants
(University of Kansas, 2020-05-31)The overall aim of this research is to develop a robust, adaptable piezoelectric composite load-bearing biomaterial that when integrated with current implants, can harvest human motion and subsequently deliver electrical ... -
Effectiveness of Entertaining, Non-Traffic Related Messages on Dynamic Message Signs
(University of Kansas, 2020-05-31)This research used a fixed-base driving simulator to determine the effects of dynamic message signs (DMSs) on driver behavior. A DMS notifies drivers with safety, weather, incident, or traffic condition messages. Recently, ... -
BIOLOGICAL TREATMENT OF HYPERSALINE PRODUCED WATER USING BIOFILM TECHNOLOGY
(University of Kansas, 2020-05-31)Gas and oilfield produced water (PW) is associated with severe water quality issues, such as high salinity and high fractions of refractory organic matter. Sustainable management strategies for PW are a major challenge due ... -
