A Comparative Study Of Spectrum Sensing Methods For Cognitive Radio Systems, Mohammad Shakib Apu

Theses and Dissertations

With the increase of portable devices utilization and ever-growing demand for greater data rates in wireless transmission, an increasing demand for spectrum channels was observed since last decade. Conventionally, licensed spectrum channels are assigned for comparatively long time spans to the license holders who may not over time continuously use these channels, which creates an under-utilized spectrum. The inefficient utilization of inadequate wireless spectrum resources has motivated researchers to look for advanced and innovative technologies that enable an efficient use of the spectrum resources in a smart and efficient manner.

The notion of Cognitive Radio technology was proposed to address …

Does Attractiveness Matter For Sex Offenders? An Examination Of Defendant Attractiveness, Defendant Gender, And Crime Severity, Adam Charles Austin

Theses and Dissertations

There has been an abundance of research showcasing an attraction-leniency bias that benefits attractive defendants of various crimes. However, this bias tends to diminish if the crime is deemed serious or if the defendant uses his or her attractiveness to commit the crime (i.e., swindle). The purpose of the current study is to investigate judgments made about a defendant being accused of a sexual offense. The study represents a 2 (gender of defendant) x 3 (attractiveness of defendant: attractive, unattractive, no picture) x 3 (crime severity: low, medium, high) factorial design.

Removal Efficiency Of Water Quality Pollutants In A Wet Detention Basin In Grand Forks, Nd, Abbie Marie Beaudry

Theses and Dissertations

It is hypothesized that the applied sampling techniques, water quality analysis, and statistical analysis predict pollutant removal efficiencies of the project site. Current practices in urban stormwater runoff are the design of systems that limit the developed peak discharge to less than or equal to the peak discharge of the pre-developed conditions. This is many times accomplished with the installation of stormwater retention, detention, or attenuation facilities that store the generated runoff from the drainage area. These are commonly known as structural Best Management Practices (BMPs). The City of Grand Forks, ND (City) implements BMPs into the stormwater management plans …

Increasing Target Language Usage In Level Ii Spanish Language Classes, Kathleen Anne Bolstad

Theses and Dissertations

In the process of learning a new language students often feel uncomfortable using their language skills in an original and spontaneous manner. In a class that is not conducted solely in the Target Language (TL), it can be difficult to motivate and encourage students to use more of the TL. In this study I explored the use of code-switching as a strategy to encourage my Level II Spanish language students to use more language without fear of making a mistake or forgetting vocabulary.

Regulation Of Proline-Directed Phosphorylation Site, Threonine 53 On Dopamine Transporter, Sathyavathi Challasivakanaka

Theses and Dissertations

The dopamine transporter (DAT) is a plasma membrane protein that clears extraneuronal dopamine (DA) and thus controls the spatio-temporal dynamics of dopaminergic neurotransmission. Also, DAT is the major target for psychostimulant substrates, amphetamine (AMPH) and methamphetamine (METH), and psychostimulant uptake blocker, cocaine (COC). DAT is a phosphoprotein with both the N- and C-termini facing toward the cytosol, with multiple phosphorylation sites on the N-terminus. DAT has a closely spaced 6-serine cluster on the distal N-terminus that is phosphorylated in a protein kinase C (PKC)-dependent manner and a recently identified proline-directed site, Thr (T) 53, that is phosphorylated in vitro by …

Development And Applications Of Gold-Silica Nanohybrids For Bioanalysis, Jiao Chen

Theses and Dissertations

In the first project, both non-spherical and spherical silica nanomateirals with hollow interiors were synthesized by a one-step soft-templating method. By simply changing the applied solvent from ethanol to 1-propanol, or 1-pentanol, three different shapes of nanomaterials, including nanosphere, nanowire, and nanotadpole, could be obtained, respectively. The effects of other factors on morphology were also systematically studied to propose a growth mechanism. It was found that the PVP-water droplet was the crucial factor on the formation of hollow interiors. Without the addition of PVP, only solid silica nanomaterials, such as solid nanoparticles, nanorods, and nanowires, were synthesized. This developed method …

Investigating The Heterogeneous Chemistry Of Polycyclic Aromatic Hydrocarbons And Other Organic Species In Atmospheric Aerosols, Richard Cochran

Theses and Dissertations

Organic aerosols (OA; organic compounds present on the surface or within aerosols) in the atmosphere may play a significant role in various atmospheric processes as well as have an impact on human health. While many primary (direct) sources of OA (POA) are known, a significant portion of OA is formed through the oxidation of primary precursors, creating secondary organic aerosols (SOA) through processes that are still unclear. This dissertation, therefore, focuses on the development of analytical methods for characterizing SOA as well as investigating the mechanism behind their formation and aerosol chemistry.

In the first phase of this work, methods …

Attachment Sites Of Irreversible Cocaine Analogs On The Dopamine Transporter, Rejwi Acharya Dahal

Theses and Dissertations

The dopamine transporter (DAT) is an integral membrane protein that reuptakes dopamine (DA) from the extracellular space into the presynaptic neuron. DAT regulates dopaminergic neurotransmission as it maintains homeostatic synaptic DA levels in the brain. Psychostimulants such as cocaine disrupt DA homeostasis as it binds to DAT and prevents reuptake of DA. Excess DA in the synapse leads to prolonged dopaminergic neurotransmission, which is associated with cocaine related euphoria often leading to addiction.

The DAT consists of 12 transmembrane domains (TMs) with N- and C-termini facing the cytoplasm. TMs 1, 3, 6, and 8 make up the core of the …

The Effect Of Self-Explanation And Strategy Training On L2 Reading Comprehension Using An Intelligent Tutoring System, Hongxia Fu

Theses and Dissertations

While research suggests that secondary language (L2) learners at postsecondary institutions face academic reading challenges, and that reading strategy training can improve primary language (L1) learners' reading comprehension, it remains a challenge to find scalable ways to deliver such training to L2 learners. Intelligent tutoring systems (ITS) have been shown to be nearly as effective as human tutors while reaching potentially unlimited numbers of learners in a variety of subjects, including reading comprehension. However, few studies have explored the effectiveness of such systems for improving L2 learners' reading comprehension. Self-Explanation Reading Training (SERT) is an instructional model that combines self-explanation …

Archival stream sampling data, collected from 1993-2011 by North Dakota state agencies, were analyzed relative to temporally-appropriate land-cover predictors generated from National Land Cover Database and National Agricultural Imagery Program products.

The 0-30 m riparian cover width was the most influential landscape predictor influencing fish structure. The 0-30 m riparian cover displayed interactive effects with 30-50 m riparian cover width and watershed land-cover disturbance. These riparian scales were identified by a …

Depression, Negative Self-Disclosure, And The Response Of Others On Facebook, Daniel Barrett Landauer

Theses and Dissertations

Depression has a number of deleterious effects on the interpersonal functioning of adolescents and emerging adults. The interpersonal theory of depression posits that depression is developed and maintained by both the behaviors of the individual and the responses of others to the individual. Adolescents and emerging adults are spending a significant amount of time interacting on social networking sites, such as Facebook, yet few studies have looked at the interpersonal behavior of depressed youth in the context of the interpersonal theory of depression. This study examined the interpersonal behavior of 328 emerging adult college students on Facebook using questionnaires related …

Dreaming Of Masculinity: The Middle English "Pearl" And The Masculine Space Of New Jerusalem, Kirby Lund

Theses and Dissertations

This thesis examines the gendering of spaces, particularly the city of New Jerusalem in the fourteenth-century Middle English dream vision Pearl. Earlier scholars have gendered this space as feminine based on the appearance of the city landscape. Instead, I examine the city in terms of both form and function to argue that New Jerusalem is a masculine space. In doing so, I hope to recognize the patriarchal control in the poem to demonstrate the masculine construction of the space, not to reinscribe patriarchy as a construct. This analysis combines the spatial theories of Henri Lefebvre and Doreen Massey with performative …
