Design Issues In Magnetic Field Coupled Array: Clock Structure, Fabrication Defects And Dipolar Coupling, Anita Kumari

USF Tampa Graduate Theses and Dissertations

Even though silicon technology is dominant today, the physics (quantum electron tunneling effect), design (power dissipation, wire delays) and the manufacturing (lithography resolution) limitations of CMOS technology are pushed towards the scaling end. These issues motivated us towards a new paradigm that contributes to a continued advancement in terms of performance, density, and cost. The magnetic field coupled computing (MFC) paradigm, which is one of the regimes where we leverage and utilize the neighbor interaction of the nanomagnets to order the single-domain magnetic cells to perform computational tasks. The most important and attractive features of this technology are: 1) room …

Magneto-Dielectric Polymer Nanocomposite Engineered Substrate For Rf And Microwave Antennas, Cesar A. Morales

USF Tampa Graduate Theses and Dissertations

This dissertation presents the first reported systematic investigation on the implementation of multilayer patch antennas over Fe3O4-based polymer nanocomposite (PNC) magneto-dielectric substrates. The PNC substrate is created by the monodispersion of Fe3O4 nanopthesiss, with mean size of 7.5nm, in a polymeric matrix of Polydimethylsiloxane (PDMS).

Recently, magneto-dielectric substrates have been proposed by several researchers as a means for decreasing the size and increasing the bandwidth of planar antennas. Nevertheless, factors such as high loss and diminished control over magnetic and dielectric properties have hindered the optimal performance of antennas. In addition, the incompatibility and elevated complexity prevents integration of conventional …

Selection And Implementation Of Technologies For The Re-Engineering Of An Existing Software System, Stan William Naspinski

USF Tampa Graduate Theses and Dissertations

A major hurdle for any company to cross is the act of re-engineering software if they wish to stay relevant. With the speed that software and technology advances, it would be ignorant for any product to stagnate. With that comes the inherent difficulties of choosing which of the older technologies to keep (if any) and which newer technologies to employ in the re-engineered solution. Once that is covered, the actual implementation presents its own set of challenges to both the decision makers and developers in the process.

This thesis describes a case study, in particular the efforts put forth to …

Live Video Streaming From Android-Enabled Devices To Web Browsers, Justin M. Bailey

USF Tampa Graduate Theses and Dissertations

The wide-spread adoption of camera-embedded mobile devices along with the ubiquitous connection via WiFi or cellular networks enables people to visually report live events. Current solutions limit the configurability of such services by allowing video streaming only to fixed servers. In addition, the business models of the companies that provide such (free) services insert visual ads in the streamed videos, leading to unnecessary resource consumption.

This thesis proposes an architecture of a real-time video streaming service from an Android mobile device to a server of the user's choice. The real-time video can then be viewed from a web browser. The …

Developmental Trajectories Of Self-Control: Assessing The Stability Hypothesis, James Vance Ray

USF Tampa Graduate Theses and Dissertations

A key proposition of Gottfredson and Hirschi's (1990) self-control theory is the stability hypothesis which suggests that an individual's level of self-control, once established between the ages of 8-10, is stable over the life course. Empirical results from examinations of the stability hypothesis have been mixed. Prior tests of the stability hypothesis have employed aggregate assessment methods (e.g., mean-level and correlational analyses). Such approaches fail to take into account the possibility that individual developmental pathways may differ. This study employs individual longitudinal data over a four year period for 3,249 7^th to 10^th grade subjects to assess the …

Evanescent Wave Coupling Using Different Subwavelength Gratings For A Mems Accelerometer, Al-Aakhir A. Rogers

USF Tampa Graduate Theses and Dissertations

A novel technique of coupling near-field evanescent waves by means of variable period subwavelength gratings (1.2 ìm and 1.0 ìm), using a 1.55 ìm infrared semiconductor laser is presented for the use of an optical MEMS accelerometer. The subwavelength gratings were fabricated on both glass and silicon substrates respectively.

Optical simulation of the subwavelength gratings was carried out to obtain the maximum coupling efficiency of the two subwavelength gratings; the grating thickness, grating width, and the grating separation were optimized. This was performed for both silicon and glass substrates.

The simulations were used to determine the total system noise, including …

Design, Synthesis And Test Of Reversible Circuits For Emerging Nanotechnologies, Himanshu Thapliyal

USF Tampa Graduate Theses and Dissertations

Reversible circuits are similar to conventional logic circuits except that they are built from reversible gates. In reversible gates, there is a unique, one-to-one mapping between the inputs and outputs, not the case with conventional logic. Also, reversible gates require constant ancilla inputs for reconfiguration of gate functions and garbage outputs that help in keeping reversibility. Reversible circuits hold promise in futuristic computing technologies like quantum computing, quantum dot cellular automata, DNA computing, optical computing, etc. Thus, it is important to minimize parameters such as ancilla and garbage bits, quantum cost and delay in the design of reversible circuits.

Inside And Outside Southern Whiteness: Film Viewing, The Frame, And The Racing Of Space In Yoknapatawpha, Peter Lurie

English Faculty Publications

Though neither film nor film viewing is ever named in As I Lay Dying, both the apparatus of cinema and what we might term its sociohistorical effects are evoked powerfully by and in the novel. These include the passing before the reader’s “gaze” of the discrete, separate “frames” of the various characters’ monologues, as well as, in particular section, a fascination with watching machinery that resembled the interest of early film biewers in the cinematic apparatus (see Doane 108).

If Vardaman and his family are not explicitly depicted as film viewers, they nevertheless show signs of what has been …

Repugnant Aboriginality: Leanne Howe’S Shell Shaker And Indigenous Representation In The Age Of Multiculturalism, Monika Siebert

English Faculty Publications

Surprisingly for a novel evidently invested in representations of contemporary Choctaw traditionalism as a viable alternative to settler society, LeAnne Howe’s 2001 Shell Shaker gives unrelenting play to the gruesomeness, horror even, of the traditional rituals it depicts, at the risk of reinforcing stereotypes of Indian savagery. And yet, these depictions of the repugnant, that is, of ancient practices now prohibited by law or found reprehensible by a public sense of ethics, allow Howe to escape the integrative thrust of contemporary multiculturalism by pre-emptying identification through difference, an interpretive logic according to which we are all the same because we …

Preface: Monsters And Mormons, Terryl Givens

English Faculty Publications

In the nineteenth century, Mormonism seemed grist for everybody's mill. Humorists like Artemus Ward and Mark Twain made hay out of polygamy; conspiracy theorists like Thomas deWitt Talmage imputed President Garfield's assassination to the Mormons; pseudo-memoirists like "Maria Ward" recounted their seduction, imprisonment, and torture at the hands of Mormon mesmerists; the Republican jump-started their political party with a promise to expunge the Mormon "relic of barbarism"; and pulp fiction writers and serious novelists alike fueled sales with stories of bloodthirsty Danites, lecherous elders, and grief maddened Mormon wives who murdered competitors.

Log-Periodic Microstrip Patch Antenna Miniaturization Using Artificial Magnetic Conductor Surfaces, Ahmad Tariq Almutawa

USF Tampa Graduate Theses and Dissertations

Microstrip patch antennas are attractive for numerous military and commercial applications due to their advantages in terms of low-profile, broadside radiation, lowcost, low-weight and conformability. However, the inherent narrowband performance of patch antennas prohibits their use in systems that demand wideband radiation. To alleviate the issue, an existing approach is to combine multiple patch antennas within a log-periodic array configuration [1]. These log-periodic patch antennas (LPMAs) are capable of providing large bandwidths (>50%) with stable broadside radiation patterns. However, they suffer from electrically large sizes. Therefore, their miniaturization without degrading the bandwidth performance holds promise for extending their use …

Physical Activity Promotion Among School-Aged Children Using Pedometers And Rewards, Kari E. Ek

USF Tampa Graduate Theses and Dissertations

Physical activity is important for children as many children are considered overweight or obese. The benefits of exercise have been demonstrated in empirical studies across all age ranges (Horne, Hardman, Lowe, & Rowlands, 2009; Kelly et al., 2004; Louie & Chan, 2003; Southard & Southard, 2006). In the current study, a multiple baseline design across participants was used to assess the effectiveness of goal setting, reinforcement contingencies, and pedometers that provide feedback to increase step count of 5 participants. During baseline each participant wore a sealed pedometer to assess the average steps the participants took per day. After baseline, each …

Grouper: A Packet Classification Algorithm Allowing Time-Space Tradeoffs, Joshua Adam Kuhn

USF Tampa Graduate Theses and Dissertations

This thesis presents an algorithm for classifying packets according to arbitrary (including noncontiguous) bitmask rules. As its principal novelty, the algorithm is parameterized by the amount of memory available and can customize its data structures to optimize classification time without exceeding the given memory bound. The algorithm thus automatically trades time for space efficiency as needed. The two extremes of this time-space tradeoff (linear search through the rules versus a single table that maps every possible packet to its class number) are special cases of the general algorithm we present. Additional features of the algorithm include its simplicity, its open-source …
