Current sensing atomic force microscopy study of aging mechanism of the nafion membranes due to thermal annealing
(University of Missouri--Kansas City, 2011-09-14)
Proton transport properties of Nafion 212 and Nafion 115 membranes have been
studied using current sensing atomic force microscopy to reveal changes of the ionic domains
and the local ionic conductivity distribution in ...
A musculoskeletal model of a subject specific knee joint with menisci, during the stance phase of a walk cycle
(University of Missouri--Kansas City, 2012-01-26)
Movement simulation and musculoskeletal modeling can predict muscle forces, but current methods are hindered by simplified representations of joint structures. Simulations that incorporate muscle forces, an anatomical ...
Performance standards for walk-in coolers and freezers in the United States as a function of local weather conditions
(University of Missouri--Kansas City, 2011-05-26)
Walk-in coolers and freezers are medium (~35º F) and low (~-10º F to -20º F)
temperature commercial food preservation equipment, with high market demand. There is
considerable potential for energy savings through ...
Investigation of strength of a hybrid adhesive anchor system used in precast concrete welded repair applications subjected to tensile and eccentric shear loading
(University of Missouri--Kansas City, 2012-08-28)
A common precast industry repair for missing or misplaced connection plates is
the use of an adhesive anchor system to fasten repair plates to precast members.
Typically, the repair plate will experience elevated ...
Evaluation of Cement-Based Reactive Media for Contaminant Remediation
(University of Missouri -- Kansas City, 2018)
Water contaminated with heavy metals, arsenic, and other industrial pollutants
poses a severe risk to human health. Reactive media present an opportunity to intercept
contaminants but have high material or environmental ...
Entrained Air-Void System For Durable Highway Concrete
(2020)
In the US, the most commonly used F-T test method is AASHTO T 161 “A.” The equipment for variant A of the test is relatively low cost (~$22, 000) and compact. The relatively low cost stems from the basic construction of a ...
Modeling Pressurized Stairwells with Open Doors
(University of Missouri -- Kansas City, 2019)
Stairwells are essential to occupant exiting from tall (high-rise) buildings. In order to
maintain tenable environments in the stairwells, modeling building and fire codes allow the
use of a stair pressurization system ...
Development of Aerial-Ground Sensing Network: Architecture, Sensor Activation, and Spatial Path-Energy Optimization
(University of Missouri -- Kansas City, 2019)
The advent of autonomous navigation, positioning, and in general robotics
technologies has enabled the maturity of small to miniature-sized unmanned aerial
vehicles (UAVs; or colloquially called drones) and their wide ...
Hybrid Fuzzy-Bayesian Dynamic Decision Support Tool for Resource-Based Scheduling of Construction Projects
(University of Missouri--Kansas City, 2017)
This dissertation proposes a flexible and intelligent decision support tool for scheduling
and resource allocation of construction projects. A hybrid Fuzzy-Bayesian scheduling network
and a new optimization model and ...
Age and Gender Effects on Strain Response and Biomechanical Performance of C57BL/6 Mice
(University of Missouri -- Kansas City, 2018)
Osteoporosis is a systemic skeletal disease resulting in low bone mass and micro architectural deterioration of bone tissue. It causes a consequent increase in bone fragility and susceptibility to fracture. This age-related ...
Hydrologic Analysis of Rain Garden Performance
(2016)
Urban flooding became a significant issue for many cities worldwide due to rapid urbanization and increased impervious areas over the past two decades ([1]). Rain gardens are considered to be an economically-friendly ...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and ...
Pressure-impulse diagrams using finite element analysis for reinforced concrete columns subjected to blast loading
(University of Missouri--Kansas City, 2011-08-11)
Reinforced concrete is one of the prime building materials widely used to construct
protective structures. One of the purposes of this project is to study the non-linear response of
reinforced concrete structures when ...
Assessment of Seismic Hazards along the Northern Gulf of Aqaba
(2014-09-26)
Aqaba and Elat are very important port and recreation cities for the Hashemite Kingdom of Jordan and Israel, respectively. The two cities are the most susceptible to damage from a destructive future earthquake because they ...
Modeling the soft tissues of the knee joint
(2013)
Computational modeling of the knee helps us better understand the forces and strains placed on knee structures, such as the ligaments and cartilage, during ambulatory activities. With better understanding of ligament strains ...
Optimization of Bridge Approach Slab
(University of Missouri--Kansas City, 2010)
Every US state Department of Transportation has its own practice for design and construction of Bridge Approach Slab (BAS). The objective of this thesis is to explore the usage of alternate innovative structural solution ...
Seismic response analysis for raised access floor and computer equipment systems considering vertical ground motions
(University of Missouri--Kansas City, 2014)
The damage and failure of computer equipment typically supported by raised
