The increasing developments of computational fluid dynamics (CFD) in the recent years have opened the possibilities of low-cost yet effective method for improving HVAC systems in design phase, with less experiment required. This work presents numerical simulations of thermal comfort and contaminant removal for two typical working spaces where these factors are critical: a …

Analysis Of Flow In A 3d Chamber And A 2d Spray Nozzle To Approximate The Exiting Jet Free Surface, Chin Tung Hong

USF Tampa Graduate Theses and Dissertations

The purpose of this investigation is to analyze the flow pattern of cooling fluids in the 3D "twister-effect" mixing chamber and to approximate the free surface behaviors exiting the 2D spray nozzle. The cone angle and free surface height located at the end of the free surface are two significant factors to determine the spraying area on a heated plane. This process is a reasonable representation of many industrial cooling application. The whole system consists of 4 inlet tubes connected to the top of the mixing chamber, and the spray nozzle is located under the chamber. Four different refrigerants, like …

An Exploratory Study That Examines Perceptions, By The Regulated Community, On The Effectiveness Of Air Quality Permitting For Clark County, By The Department Of Air Quality And Environmental Management, Scott Jelinek

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Clean Air Act of 1970 (CAA) made the Environmental Protection Agency (EPA) responsible for establishing and maintaining federal programs that control air quality. In turn, each state was delegated responsibility for air quality within its borders, although this responsibility may be shared with Native Americans or tribal lands. In many states, jurisdiction has been delegated to regional or local agencies that are then responsible for air quality in their respective air basins. Even though terrain or water bodies define the physical boundaries of air basins, they are usually designated by County boundaries for regulatory convenience (Wooley, David R., 1997).

Modeling Of Qe, I-V Characteristics Of Msm (Metal-Semiconductor-Metal) Mercuric Iodide Thin Films With MediciTm, Vikram Rupavatharam

USF Tampa Graduate Theses and Dissertations

Mercuric Iodide is the most promising of all semiconductor materials currently under investigation for use as radiation detectors at room temperature. While substantial studies have been conducted on single crystal HgI₂, polycrystalline HgI₂ remains a comparatively less studied form.

The HgI₂ films are deposited on TEC-15 LOF glass with a Tin Oxide (SnO₂) coating which acts as the growth surface and front contact. The back contact, Palladium (Pd), is deposited by sputtering through a shadow mask. The films are circular in shape with an approximate diameter of 2.5 cm and thicknesses ranging from 50-600 …

Real-Time Registration And Display Of Confocal Microscope Imagery For Multiple-Band Analysis, Scott E. Budge, A.M. Mayampurath, J.C. Solinsky

Electrical and Computer Engineering Faculty Publications

Multiple images acquired in real-time from a confocal microscope in different illumination wavebands are used to construct a three-dimensional understanding of living cell signal propagation. Registration, fusion, and display of these images are performed in real-time using field programmable gate array (FPGA) technology to allow the biological scientist to observe time critical signaling processes as they occur. The registration and display system operates at a rate of up to 15 frames/s, and performs dark offset correction and noise reduction, followed by non-linear correction for lens warp and focal plane tilt, and finally correction for spatial mismatch between the different wavebands. …

Electrotransformation Of Clostridium Thermocellum, Michael V. Tyurin, Sunil G. Desai, Lee R. Lynd

Dartmouth Scholarship

Electrotransformation of several strains of Clostridium thermocellum was achieved using plasmid pIKm1 with selection based on resistance to erythromycin and lincomycin. A custom-built pulse generator was used to apply a square 10-ms pulse to an electrotransformation cuvette consisting of a modified centrifuge tube. Transformation was verified by recovery of the shuttle plasmid pIKm1 from presumptive transformants of C. thermocellum with subsequent PCR specific to the mls gene on the plasmid, as well as by retransformation of Escherichia coli. Optimization carried out with strain DSM 1313 increased transformation efficiencies from <1 to (2.2 􏰍 0.5) 􏰎 105 transformants per 􏰃g of plasmid DNA. Factors conducive to achieving high transformation efficiencies included optimized periods of incubation both before and after electric pulse application, chilling during cell collection and washing, subculture in the presence of isoniacin prior to electric pulse application, a custom-built cuvette embedded in an ice block during pulse application, use of a high (25-kV/cm) field strength, and induction of the mls gene before plating the cells on selective medium. The protocol and preferred conditions developed for strain DSM 1313 resulted in transformation efficiencies of (5.0 􏰍 1.8) 􏰎 104 transformants per 􏰃g of plasmid DNA for strain ATCC 27405 and 􏰁1 􏰎 103 transformants per 􏰃g of plasmid DNA for strains DSM 4150 and 7072. Cell viability under optimal conditions was 􏰁50% of that of controls not exposed to an electrical pulse. Dam methylation had a beneficial but modest (7-fold for strain ATCC 27405; 40-fold for strain DSM 1313) effect on transformation efficiency. The effect of isoniacin was also strain specific. The results reported here provide for the first time a gene transfer method functional in C. thermocellum that is suitable for molecular manipulations involving either the introduction of genes associated with foreign gene products or knockout of native genes.

2004 Freshwater Mussel Survey Of The Big Piney River And Roubidoux Creek, Pulaski County, Missouri, M. Christopher Barnhart, Jennifer Wigger, Matt Duzan

College of Natural and Applied Sciences

Native freshwater mussels are an ecologically important group of aquatic mollusks. This group is of particular concern to conservation biologists because many species are classified as species of conservation concern (SCC). The freshwater mussel community of the Big Piney River and Roubidoux Creek, on and in the vicinity of Fort Leonard Wood, was previously surveyed by Sternburg et al. (1998). The present project was a resurvey of the area to determine the current status of the mussel community, so that appropriate measures can be taken to preserve and protect that community.

From the work site, the decedent drove the …

Social Engineering In The Age Of Ai, Mohammad A. Saleh

Cybersecurity Undergraduate Research Showcase

The next great invention is artificial intelligence. AI has grown rapidly over the last 15 years and has brought both advantages and disadvantages to everyday society. One of the most concerning disadvantages highlighted in recent years is the rise of social engineering attacks. Social engineering comes in many different forms, making it difficult to identify at times. With the development of AI, these attacks have become even harder to detect, prevent, and stop. This research essay explores the different types of AI-driven social engineering attacks, how they occur, why they happen, and the impact they have on individuals and organizations.

Disorder-Induced Depression Of The Curie Temperature In Mechanically Milled Gdal2, Marco Morales Torres, D. S. Williams, Paul M. Shand, C. Stark, Thomas M. Pekarek, Lanping Yue, Valeri G. Petkov, Diandra Leslie-Pelecky

Materials Research Science and Engineering Center: Faculty Publications

The effect of disorder on the ferromagnetic transition is investigated in mechanically milled GdAl₂. GdAl₂is a ferromagnet when crystalline and a spin glass when amorphous. Mechanical milling progressively disorders the alloy, allowing observation of the change from ferromagnetic to a disordered magnetic state. X-ray diffraction and pair-distribution-function analysis are used to determine the grain size, lattice parameter, and mean-squared atomic displacements. The magnetization as a function of temperature is described by a Gaussian distribution of Curie temperatures. The mean Curie temperature decreases with decreasing lattice parameter, where lattice parameter serves as a measure of defect concentration. …

Slurry Sand Content And Concrete Interaction In Drilled Shaft Construction, Gregory Gene Deese

USF Tampa Graduate Theses and Dissertations

Due to the widespread use of drilled shafts in state and federal highway bridges, strict regulation of the design and construction has been imposed by the respective agencies. However, documented cases of anomalies and/or poorly performing shafts continue to arise. To this end, this thesis investigates several aspects of drilled shaft construction that may affect the quality of the finished product. These areas include bentonite slurry properties and performance as well as reinforcement cage and concrete flow interactions.

Recent research indicates tremie poured concrete does not flow as predicted. Instead of even rising, a differential between the height of concrete …
