Finite Element Simulation of Precast/Prestressed Insulated Sandwich Panels Optimized for Construction of Government Facilities

Nickerson, Joseph (2014-05-02)

This report discusses the development of finite element modeling methodologies for the static and dynamic response of insulated sandwich panels to uniform pressure loads. Experimental testing, which included solid panel ...

A Finite Element Study of an Elastic- Plastic Axisymmetric Sinusoidal Surface Asperity in Contact Against a Rigid Flat with Strain Hardening

Bhandari, Geetanj (2018-04-17)

With the advancement in science and the introduction of new technology, computational modelling of contact between rough surfaces has attracted a great deal of attention. Researchers have developed many rough surface contact ...

A Finite Volume Implementation of the Shallow Water Equations for Boussinesq Gravity Currents

Hatcher, Thomas, Jr. (2012-07-16)

The shallow water equations (SWE) are a powerful tool for modeling the propagation of gravity currents (GC) because of their relative simplicity, computational efficiency and accuracy. Finite difference solutions, either ...

Finite-Element Modeling of a Damaged Prestressed Concrete Bridge

Shapiro, Kelli (2007-05-15)

Spans 10 and 11 of the Interstate Highway 565 bridge structure in Huntsville, Alabama were noticed to be cracked shortly after their construction. Alabama Department of Transportation (ALDOT) employees investigated and ...

Finite-Element Modeling of Early-Age Concrete Behavior

Yalin, Liu (2018-07-24)

Early-age cracking of concrete may influence the long-term durability of a structure. Cracking occurs when the tensile stress in concrete exceeds its tensile strength. Early-age stress development in concrete is influenced ...

Finitely Generated Modules Over Noncommutative Chain Rings

Scible, Greggory (2011-10-26)

The notion of a right chain ring, a ring whose lattice of right ideals is linearly ordered by inclusion, is a generalization of a valuation ring. In this work we investigate properties of right chain rings and the structure ...

Firm Hedging Decision and Its Value Implication

JIN, HAN (2022-07-21)

In Chapter 1, we study the impact of increased transparency in the reporting of OCI on firms’ foreign currency cash flow hedging practice and the value relevance of this change. We find a reduced level of foreign currency ...

First Generation College Students in the Alabama Community College System: Outcomes and Implications for School Counselors and Educators

Renee, Maegan (2019-08-08) ETD File Embargoed

Enrolling in and completing college can be especially challenging for first generation in college (FGC) students. The purpose of the present quantitative study was to investigate the demographic and academic characteristics ...

First Innovator States: An Ecological Analysis of Innovation and Diffusion of Policies to Address College Student Financial Insecurity in the American States.

Cellon, Jonathan (2020-04-08)

The issue of college student financial insecurity has risen to the political agenda of post-secondary institutions and states since the Recession of 2007 – 2009. This need is driven by stark increases in the cost of college ...

First Principle Studies on Ground and Excited Electronic States: Chemical Bonding in Main-Group Molecules, Molecular Systems with Diffuse Electrons, and Water Activation using Transition Metal Monoxides

Ariyarathna, Isuru (2021-03-01)

Potential energy profiles can be used to investigate the origins of chemical bonding of molecules. Such profiles were adopted to show the propagation of lone pair electrons of N2(X1Σg+) to the vacant orbital of O(1D) or ...

First Steps for First Gen: An exploration of the experiences of first generation college students during the formal processes of enrolling in higher education

Moran, Allison (2024-04-22)

The Center for First Generation College Student Success (2020) defined first generation college students (FGCS) as, “an undergraduate student whose parents do not have a bachelor’s or higher degree.” FGCS have to navigate ...

First Year Student Perceptions and Effectiveness of Social Media Influence in College of Agriculture Retention Efforts in Southeastern Land-Grant Universities

Wise, Jamie (2020-11-20)

With young adults leading the way in social media usage, it has not gone unnoticed by Colleges of Agriculture administrators who want to connect with students where they are. This generation is more wired than any generation ...
