The Critical Difference Seismic Design Can Make For A Reinforced Concrete Building Located In Oxford, Mississippi, Naim Daghmash
The Critical Difference Seismic Design Can Make For A Reinforced Concrete Building Located In Oxford, Mississippi, Naim Daghmash
Honors Theses
The Senior Design course at the University of Mississippi requires the completion of a capstone project. One part of the capstone project is a complete structural design of the NOLA, an ongoing construction in the city of Oxford in Mississippi. The course requires the NOLA to be designed according to gravity loads, meaning the forces act in the downward direction towards the earth’s surface. Some loading mechanisms that could occur in a different direction than gravity are seismic loads, which are earthquake-generated loads. I was not required by my instructors to consider the effect of an earthquake on the structural …
Damage Detection Using Destructive Testing Of A Reinforced Concrete Slab, Michael Edward Daves
Damage Detection Using Destructive Testing Of A Reinforced Concrete Slab, Michael Edward Daves
Electronic Theses and Dissertations
Visual inspection is one of the primary tools for evaluating the health of bridges as more reach or exceed their intended lifespan. Bridge deterioration must be monitored to ensure continued safety, so owners need maintenance reports to decide on corrective actions. Strategic repair can offer asset managers the benefit of saving money and time; thus, knowing where to locate and what type of repairs can be challenging when relying on visual techniques alone. A tool designed to aid bridge inspectors is the SHE^tm program, which quantitatively measures damage location and severity for any set of time data.

Electronic Theses and Dissertations
The Mississippi Alluvial Plain (MAP) is a premier region for irrigated agriculture in the United States producing approximately 9 billion dollars in annual revenues. The region receives around 138 cm of precipitation annually; however irrigation is necessary to maximize crop yields as most of the precipitation does not occur during the growing season. There are 8 million irrigated acres within the Mississippi Alluvial Plain. The source of most of the irrigated water is the surficial aquifer in the Mississippi Embayment the Mississippi River Valley Alluvial Aquifer (MRVAA) and due to the reliance on irrigation for maximum crop yields recent potentiometric …

Investigating The Use Of Passive Acoustics As A Surrogate Method Of Monitoring Coarse Bedload Transport In Rivers And Streams Via Laboratory Experiments And Field Studies, Bradley Goodwiller
Electronic Theses and Dissertations
The movement of coarse gravel in rivers in streams is important for many applications including wildlife habitation, river morphology, infrastructure maintenance and marine navigation. Physical sampling remains the most accurate method of determining coarse bedload transport but it can be expensive, dangerous and flow intrusive. Surrogate methods of monitoring bedload transport is an active area of research worldwide. One such method is the use of passive acoustics to record the sound generated when gravel particles in motion impact each other or the particles on the bed. This dissertation presents research and development that has been conducted on three key areas …

Electronic Theses and Dissertations
A nation’s economy and prosperity depend on an efficient and safe transportation network for public mobility and freight transportation. A country’s road network is recognized as one of the largest public infrastructure assets. About 93 percent of 2.6 million miles of paved roads and highways in the United States (U.S.) are surfaced with asphalt. Longitudinal roughness, pavement cracking, potholes, and rutting are the major reasons for rehabilitation of asphalt roads. Billions of dollars are required annually for the maintenance and rehabilitation of road networks. If timely maintenance and rehabilitation are not performed, the pavement damages inflicted by heavy traffic repetitions …

Evaluating The Effects Of Water Influx On The Mississippi Sound: Current Vs. Historical Relationships, Jarett Lee Bell
Electronic Theses and Dissertations
This research investigated the influence of the opening of the Bonnet Carre Spillway and other fresh water inputs on the Mississippi Sound. The Bonnet Carre Spillway was completed in 1931 and was constructed to protect New Orleans whenever the Mississippi River is at flood stage. The spillway drains into Lake Pontchartrain a brackish-water lagoon north of New Orleans which then drains into Lake Borgne and subsequently into the Mississippi Sound. The inflow of water from the spillway changes the water chemistry of all receiving water bodies and impacts the waters of the Mississippi Gulf Coast. We collected in-situ temperature specific …
Field Testing And Simulation Of Vadose-Zone Recharge Wells In The Mississippi River Valley Alluvial Aquifer As An Artificial Recharge Method, Kyungwon Kwak
Electronic Theses and Dissertations
Increasing concerns regarding depletion of groundwater in the Delta region of Mississippi have led to a need to augment natural recharge. Infiltration basins are often one of the simplest means of artificially recharging aquifers. However the Delta has a layer of clay and silt at the surface so it is a better idea to use vadose-zone recharge wells that are not limited by the surficial layer of fine soils. The purpose of this study is to use full-scale field testing to assess the feasibility of using vadose-zone wells for artificial recharge of the Mississippi River Valley alluvial aquifer by using …

Optimizing The Performance Of Complex Engineering Systems Aided By Artificial Neural Networks, Khalil Qatu
Electronic Theses and Dissertations
In the first problem Polyetherimide graphene nanoplatelets papers (PEIGNP) were tested with different graphene loadings varying from 0-97 weight percent (WT%). The resulting stress-strain curves were utilized to develop two ANN models. Stress-controlled and strain-controlled models. Both models shoan excellent correlation to the experimental. Several Mechanical properties were calculated from the predicted stress-strain curves namely; toughness maximum strength maximum strain and maximum tangent modulus. Both models captured the same overall behavior of the PEIGNP composite. However the strain-controlled model was found to predict lower stress than the stress-controlled model. Finally a Graphical User Interface (GUI) was developed to aid in …

Determination Of Shrinkage Of Fine-Grained Soils Using 3d Scanning Technology, Hemant R. Joshi
Honors Theses
Shrinkage Limit is the moisture content parameter in fine grained soil which is related to the volume stability of the soil. The conventional method, ASTM Standard D427-04 that uses mercury has been replaced by wax method, ASTM Standard D4943-02 that uses wax and water or MT-92 that uses spray coating. This modification has certainly minimized safety concerns of the laboratory technicians by avoiding the use of the health hazardous substance, mercury (Hg) but it is not really an economic and convenient method. This thesis proposes a 3D scanning method of determining the shrinkage limit of fine grained soils. The 3D …
