A Systematic Review Of Blockchain Research And Applications In Business, Prinsa Roka Jan 2019

A Systematic Review Of Blockchain Research And Applications In Business, Prinsa Roka

Undergraduate Honors Theses

Blockchain, well-known as the Distributed Ledger Technology (DLT) behind cryptocurrencies such as Bitcoin, has attracted plenty of attention from both practitioners and academics and has begun to revolutionize the way businesses handle their day-to-day operations. DLT leads to many interesting new research topics in different business fields. In this study, we applied the systematic mapping method to review existing articles related to blockchain applications and research in different business areas (accounting, finance and banking, information systems, marketing and supply chain). Our goal is to understand the current applications and research status related to blockchain, so that we can identify research …


3d Character Modeling In Maya And Blender, Maddalyn B. Smith Jan 2017

3d Character Modeling In Maya And Blender, Maddalyn B. Smith

Undergraduate Honors Theses

Two 3D modeling programs were compared with various models, and shapes, to determine the most efficient program for students, and professors. The two modeling programs included in the research were Autodesk Maya (Maya) and Blender. Maya and Blender both provide various assets for modeling. While they are very similar, it was concluded that Blender is preferred over Maya for individuals beginning to learn 3D modeling. Meanwhile, Maya is more beneficial to those who are more experienced and seek to acquiesce skills for professional environment. For teachers who are determining which program will best fit the students needs, it is important …


Plant-Microbial Interactions Change Along A Prairie Restoration Chronosequence, Anna Herzberger May 2014

Plant-Microbial Interactions Change Along A Prairie Restoration Chronosequence, Anna Herzberger

Undergraduate Honors Theses

Soil microbial communities are critical in determining the performance and density of species in plant communities. However, their role in regulating the success of restorations is much less clear. This study assessed the ability of soil microbial communities to regulate the growth and performance of two potentially dominant grasses and two common forbs in prairie restorations. Specifically, I examined the effects of soil microbial communities along a restoration chronosequence from agricultural fields to remnant prairies using experimentally inoculated soils. The two grass species, Andropogon gerardii and Sorghastrum nutans, produced larger biomass with the agricultural inoculates and experienced a decline …


Determining The Sediment Source Area Through Petrographic Analysis Of The Hermosa Formation, Silverton, Southwestern Co, Kristina P. Pourtabib Jan 2013

Determining The Sediment Source Area Through Petrographic Analysis Of The Hermosa Formation, Silverton, Southwestern Co, Kristina P. Pourtabib

Undergraduate Honors Theses

The Pennsylvanian/Permian Hermosa Formation in southwestern Colorado is composed of arkosic sandstone, marine limestone, and shale that formed at a time when the region consisted of open-marine carbonate shelves and coastal plains. During the time of deposition, there were many tectonically active highlands in the region, including the Ancestral Rocky Mountains, San Luis Highlands, and the Uncompahgre, Emery, Zuni-Defiance-Kaibab Uplifts. Previous studies have attributed the source of the main sediment supply of the Hermosa Formation to the Uncompahgre branch of the Ancestral Rocky Mountains with smaller amounts of elastics from the Defiance-Zuni uplifts (Wengerd and Matheny, 1958; Wengerd and Strickland, …


Analysis Of Entanglement And Logic Gate Implementation In Generic Two-Level Systems, Jonathan Jones Jan 2012

Analysis Of Entanglement And Logic Gate Implementation In Generic Two-Level Systems, Jonathan Jones

Undergraduate Honors Theses

An N-atom quantum system interacting with a single cavity field mode serves as an intuitive and useful model for many areas of quantum information science. We extend this model to describe artificial systems composed of quantum dots and Josephson junction devices as well. In addition, we include the dipole interactions characteristic of such systems. We use Bell-type inequalities and concurrence to examine the development of entanglement in the specific cases of two- and three-atom systems, and find that the effect of dipole interactions on entanglement generation depends heavily on the initial state of the system. Finally, we propose a …


Analysis Of Bisphenol A (Bpa) In Local Waters And In Pvc Pond Liner, Brandon Bills Jan 2012

Analysis Of Bisphenol A (Bpa) In Local Waters And In Pvc Pond Liner, Brandon Bills

Undergraduate Honors Theses

Concentrations of the endocrine disrupter bisphenol A (BPA) were determined for three water samples from the watershed of Charleston, IL, USA. The analytical approach employed solid phase extraction in conjunction with GC/MS-SIM analysis and yielded a limit of detection of 30 ppt (parts per trillion). The local waterways Town Branch. Cassel Creek and Embarras River showed concentrations of 58(11) ppt, 89(3) ppt, and 32(9) ppt respectively. Additional measurements of BPA availability from aqueous laboratory extractions of a commercial PVC pond liner have been initiated. Preliminary results indicate significant BPA release from the pond liner, dependent upon extraction conditions.
