Effects Of Radial Thermal Gradients In Hplc, Jennifer Splan
Effects Of Radial Thermal Gradients In Hplc, Jennifer Splan
Honors Theses, 1963-2015
Due to the widespread use of chromatography, improving efficiency in chromatography is continually an area of interest. Researchers have suggested that the method of column temperature control influences efficiency. To insure reproducible retention times, HPLC columns are often thermostated with a water jacket. Under such conditions, however, a radial thermal gradient may arise from the heat produced by friction between the stationary and mobile phases. If the core of the column is allowed to warm up while the walls are kept at a constant temperature, the solute in the core of the column will elute faster than will that at …
An Examination Of Virtual Reality Modeling Language And Its Implications For The Future Of The World Wide Web, Mitch L. Hamelau
An Examination Of Virtual Reality Modeling Language And Its Implications For The Future Of The World Wide Web, Mitch L. Hamelau
Honors Theses, 1963-2015
This project examines the current and future capabilities of Virtual Reality Modeling Language (VRML). VRML is first looked at in terms of its own current capabilities and limitations and then in terms of the impact that it will have on the World Wide Web. Some examples of future changes to the World Wide Web that may come about due to VRML are examined. Then a specific application is used as an example of the advantages VRML provides for developers who use the World Wide Web.
Researching The Growing Technology Of Virtual Reality, David Weinandt
Researching The Growing Technology Of Virtual Reality, David Weinandt
Honors Theses, 1963-2015
Virtual reality is a fast growing technology within the computer science field. The current technologies using virtual reality are invading our everyday lives such as the medical applications of ultrasound and catscans. This technology is changing how we view data, as well as how common user applications are being constructed. The primary focus of the thesis is on the computer code necessary to compute the tracking of users. How the environment is generated, how users and objects are viewed by the computer, and how tracking codestructured on a basic level are some of the questions I cover in my thesis. …
Using Genetic Algorithms To Solve The Geometric Traveling Salesperson Problem, Michael Criswell
Using Genetic Algorithms To Solve The Geometric Traveling Salesperson Problem, Michael Criswell
Honors Theses, 1963-2015
Genetic Algorithms use life as their model to solve difficult problems in computer science. They use a collection of possible solutions to find an optimal solution in extremely large search spaces. They follow biological processes such as crossover and mutation and implement Darwinian natural selection to use the better solutions to create more possible solutions until an optimal solution has been found. The Traveling Salesperson Problem lies within a class of problems called NP. These problems are not solvable in a reasonable amount of time using classical methods. Genetic Algorithms are an alternative method for attempting to solve such problems. …

Residential Radon-222 Exposure And Lung Cancer: Exposure Assessment Methodology, R. William Field, Daniel J. Steck, Charles F. Lynch, Christine P. Brus, John S. Neuberger, Burton C. Kross

Although occupational epidemiological studies and animal experimentation provide strong evidence that radon-222 (222Rn) progeny exposure causes lung cancer, residential epidemiological studies have not confirmed this association. Past residential epidemiological studies have yielded contradictory findings. Exposure misclassification has seriously compromised the ability of these studies to detect whether an association exists between 222Rn exposure and lung cancer. Misclassification of 222Rn exposure has arisen primarily from: 1) detector measurement error; 2) failure to consider temporal and spatial 222Rn variations within a home; 3) missing data from previously occupied homes that currently are inaccessible; 4) failure to link …

The Temperature Dependence Of Ultra Violet Sulfur Dioxide Absorption Cross Sections, Alexis Brunner
The Temperature Dependence Of Ultra Violet Sulfur Dioxide Absorption Cross Sections, Alexis Brunner
Honors Theses, 1963-2015
Atmospheric sulfur dioxide data became available in 1982 during and after the eruption of El Chichon, when the Total Ozone Mapping Spectrometer, TOMS, received increased absorption in the shortest wavelength channels of the instrument. TOMS was designed to map the daily global total ozone field. The increased absorption was later determined to be due to sulfur dioxide because it is a gaseous volcanic substituent that has corresponding absorption to that seen in the TOMS data. Currently there is no way to develop an algorithm that will accurately subtract the effects of sulfur dioxide from the TOMS data in order to …
