Discrete Film Cooling In A Rocket With Curved Walls, Jonathan F. Mccall

Theses and Dissertations

This study quantified the effects of discrete wall-based film cooling in a rocket with curved walls. Simulations and experiments showed decreasing with wall radius of curvature, holding jet diameter constant, improves net heat flux reduction (NHFR) and adiabatic effectiveness (η) for 90˚ compound injected cylindrical jets, though η is reduced at the highest curvature. NHFR and η improved further with a high favorable stream-wise pressure gradient (K=2.1x10^-5) at all tested blowing ratios, but were affected little by a high density ratio (DR=1.76) using carbon dioxide as the coolant. Experiments were run at a Reynolds number of 31K and …

Fatigue Behavior Of An Advanced Sic/Sic Composite At Elevated Temperature In Air And In Steam, Devon T. Christensen

Theses and Dissertations

The fatigue behavior of an advanced Silicon Carbide/Silicon Carbide (SiC/SiC) ceramic matrix composite (CMC) was investigated at 1200 ˚C in laboratory air and in steam environments. The composite consisted of a SiC matrix reinforced with Boron Nitride (BN) coated Hi-Nicalon fibers woven into eight-harness-satin (8HS) weave plies. Tensile stress-strain behavior and tensile properties were also evaluated at 1200 ˚C. Tension-tension fatigue tests were conducted in both laboratory air and in steam at 1200 ˚C at frequencies of 0.1 Hz, 1.0 Hz, and 10 Hz. The tension-tension fatigue tests had a ratio of minimum stress to maximum stress of R = …

E-Content: Student Content Creators: Convergence Of Literacies, Joan K. Lippincott

Faculty Journal Articles

There is ample evidence that students are creating all types of digital content and disseminating it via the Internet. When they graduate from universities and colleges and enter such fields as business, education, government, medicine, research, or the arts, they will continue to produce digital content. Employers often select new graduates for positions in the expectation that they will take on technology-intensive assignments related to the Web presence of the organization. While in school, many students create digital materials without guidance from faculty, information technologists, or librarians, but such products are typically recreational and do not have the hallmarks of …

Egoviz – A Mobile Based Spatial Interaction System, Keith Gardiner, Junjun Yin, James Carswell

Articles

This paper describes research carried out in the area of mobile spatial interaction and the development of a mobile (i.e. on-device) version of a simulated web-based 2D directional query processor. The TellMe application integrates location (from GPS, GSM, WiFi) and orientation (from digital compass/tilt sensors) sensing technologies into an enhanced spatial query processing module capable of exploiting a mobile device’s position and orientation for querying real-world 3D spatial datasets. This paper outlines the technique used to combine these technologies and the architecture needed to deploy them on a sensor enabled smartphone (i.e. Nokia 6210 Navigator). With all these sensor technologies …

Vectors And Methods For Enhanced Cell Longevity And Protein Expression, Bruce A. Webb, Jeremy Kroemer

Entomology Faculty Patents

It is the object of the current invention to provide methods and compositions relating to the expression of vankyrin proteins in cell lines to increase their viability, longevity and capacity for protein production. The inventors have discovered that the expression of P-ank-1 and I²-ank-3 proteins in cell culture has increased the cells' longevity and capacity for endogenous and/or heterologous target protein production. Specifically, the present invention relates to the enhanced expression of endogenous and/or heterologous target proteins/polypeptides in recombinant cells that are also expressing P-ank-1 and/or I²-ank-3 protein compared to expression host cells that are not …

Sustainability In Practice: A Study Of The Sustainable Behaviors Of Students At The Univeristy Of Tennessee At Chattanooga, Audrey Glor

Honors Theses

Sustainable behaviors, such as recycling, are increasingly important as the world's population continues to rise. While many attempts have been made at various institutions, recycling on a grand scale has yet to become a social reality. This study was designed to look at the three broad factors influencing an individual's recycling behavior: social pressure, knowledge base, and convenience. It was hypothesized that social pressure would have the greatest influence on an individual's recycling behavior, while not overlooking the importance of the other two factors. A questionnaire was employed to collect data from a sample population at the University of Tennessee …

Elliptical Polarizers, Tags And Identification Systems Using Frequency Selective Surfaces, Glenn Boreman, Daniel Mullally, Jeffrey Tharp

UCF Patents

An optical combination includes a substrate, a linear polarizer on the substrate, and a first frequency selective surface (FSS) based elliptical polarization filter on the linear polarizer. The first FSS comprises at least one periodic pattern of spaced apart electrically conductive lines having a sub-wavelength line-to-line spacing orientated along a first axis. The pattern is operable to impose a phase differential for one orthogonal linear polarization state relative to the other linear polarization state for electromagnetic radiation having a wavelength between 400 nm and 1 mm, such as 1 um to 12 um. An identification system and associated method for …

Studies On The Performance And Impact Of Channel Estimation In Mimo And Ofdm Systems, Michael David Larsen

Theses and Dissertations

The need for reliable, high-throughput, mobile wireless communication technologies has never been greater as increases in the demand for on-the-go access to information, entertainment, and other electronic services continues. Two such technologies, which are at the forefront of current research efforts, are orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) systems, their union being known simply as MIMO-OFDM. The successful performance of these technologies depends upon the availability of accurate information concerning the wireless communication channel. In this dissertation, several issues related to quality of this channel state information (CSI) are studied. Specifically, the first part of this dissertation …
