Stochastic Simulation Of Lagrangian Particle Transport In Turbulent Flows, Guangyuan Sun

Theses and Dissertations

This dissertation presents the development and validation of the One Dimensional Turbulence (ODT) multiphase model in the Lagrangian reference frame. ODT is a stochastic model that captures the full range of length and time scales and provides statistical information on fine-scale turbulent-particle mixing and transport at low computational cost. The flow evolution is governed by a deterministic solution of the viscous processes and a stochastic representation of advection through stochastic domain mapping processes. The three algorithms for Lagrangian particle transport are presented within the context of the ODT approach. The Type-I and -C models consider the particle-eddy interaction as instantaneous …

"[B]Reaking Down The Walls, And Crying To The Mountains"--Isaiah 22:5: Dystopia And Ethics Of The Catcher In The Rye, Megan Marie Toone

Theses and Dissertations

Reading The Catcher in the Rye as dystopian fiction requires critical responsibility to evaluate the ethicality of the protagonist's sense of others and self, to assess the moral nature of the novel's dystopian world, and to evaluate the protagonist's agency or capacity to change his world or himself. The novel presents a multifaceted dystopia existing on multiple planes in the social dogma, the reality of the presented world, and Holden's mind before and after his paradigm shift. The dystopian aspects present in the novel highlight basic ideological systems as well as agency and action within the structure. The dystopian elements …

The scales that were developed for measuring time and risk preferences have not been previously used in …

Educated Birth: Beliefs Vs. Outcomes, Lauren Presley

Human Nutrition and Hospitality Management Undergraduate Honors Theses

“Our infant mortality rate is a national embarrassment.”¹ The words seem shocking and harsh across the headline of a 2014 Washington Post article. The thought of America not only not being the best at something, but falling upsettingly behind, is a foreign concept to many who view America as a nation inferior to none. However, the statistics on infant mortality rate tell the stark truth that of 26 “wealthy” countries, the U.S. ranks last, with a sobering 6.1 deaths per 1,000 live infant births.²

Part of the Healthy People 2020 Objectives is to reduce the rate of infant …

Integrability And Regularity Of Rational Functions, Greg Knese

Mathematics Faculty Research

Motivated by recent work in the mathematics and engineering literature, we study integrability and non-tangential regularity on the two-torus for rational functions that are holomorphic on the bidisk. One way to study such rational functions is to fix the denominator and look at the ideal of polynomials in the numerator such that the rational function is square integrable. A concrete list of generators is given for this ideal as well as a precise count of the dimension of the subspace of numerators with a specified bound on bidegree. The dimension count is accomplished by constructing a natural pair of commuting …

Contribution To T He Onboard Context Sensitive Information System ( Of Commercial Aircraft, Wei Tan

Theses and Dissertations

Pilots currently use paper-based documentation and electronic systems (e.g., Electronic Centralized Aircraft Monitor (ECAM) for Airbus, and Engine Indication and Crew Alerting System (EICAS) for Boeing) to help them perform procedures to ensure safety, efficiency and comfort on commercial aircrafts. Management of interconnections among paper-based operational documents can be a challenge for pilots, especially when time pressure is high in normal, abnormal, and emergency situations. This dissertation is a contribution to the design of an Onboard Context-Sensitive Information System (OCSIS). The claim is that the use of contextual information facilitates access to appropriate operational content at the right time either …

The Psychological And Post-Colonial Approaches In Interpreting The Self And The Other In Heart Of Darkness And Things Fall Apart., Soumaya Ferchichi

Theses (Pre-2016)

To some critics, Things FallApart by Chinua Achebe, first published in 1958, comes to be the antithesis of Heart ofDarkness by Joseph Conrad, first published in 1899. In fact, this thesis will highlight Achebe's enthusiasm and nationalism that lead him to create a vivid picture of the African individual who is presented as belonging to a rich heritage of unique and complex African tradition. Achebe's characterization and representation of Africans in his novel is thought to be an ardent response to Conrad's assumed or perceived "racism." Yet, this thesis will discuss this dispute by giving new evidence to support Conrad's …

What’S Wrong With Peg?, Charles J. Higgins

Finance Faculty Works

PEG is a newer investment ratio measure of a security’s PE ratio divided by the firm’s growth rate as a percentage. It is examined and contrasted with other investment valuation measures. PEG is shown to be problematic in terms of its units of measure, in what it purports to appropriately determine, and it is non monotonic for relatively profitable firms and is only slightly indicative of correct security selection for relatively unprofitable firms.

How Is Academic Motivation In Children Influenced By Emotional Regulation?, Rosanna Pengelly

The Plymouth Student Scientist

Children’s academic achievement is influenced by motivation. Motivation, in turn, is affected by emotional regulation and children’s reactions to poor or high achievement. This study investigated academic motivation to gain an understanding of the attributions (effort, ability, difficulty and luck) made by children on their achievements in a maths test among 25 SEN children (i.e., children with emotional, behavioural and social difficulties) and 44 mainstream children. SEN children made more attributions to effort whereas mainstream children made more attributions to ability. Emotional regulation was measured using the Emotion Regulation Questionnaire (ERQ). Emotional reappraisal (i.e., reinterpreting the meaning of emotional stimuli) …

Characterising Cytotoxicity And Genotoxicity Of Chemotherapeutic Agents (Etoposide And Vincristine) On Tk6, A Human Lymphoblastoid Cell Line, Leanne Edermaniger

The Plymouth Student Scientist

The ability of the chemotherapeutic agents namely etoposide and vincristine to cause cytotoxic and genotoxic damage to the human lymphoblastoid cell line, TK6, was at the centre of this study. Four different cytotoxic assays were tested for their ability to assess the cytotoxicity of the agents as well as two genotoxic assays to examine their ability to induce DNA damage. The TK6 cell line was exposed to increasing doses of the chemotherapeutic agents and cytoxicity assessed by in vitro trypan blue, neutral red uptake, LDH leakage and the glucose oxidase assays. The trypan blue assay was deemed to be the …

Effects Of Storm-Induced Sand Scour On Patella Vulgata Off South-West Britain, Jake Jefford

The Plymouth Student Scientist

This study investigates the impacts of storm-induced sand-scour on common limpets (Patella vulgata) off south-west Britain, focussing particularly on the physical impacts of this process, as well as shore recovery. Unusually polished limpets were found living on a rocky shore (Westcombe Beach, South Devon) following a series of large storms that occurred from December 2013 to mid-February 2014. The extent of the storms was completely unprecedented, and it was one of the most exceptional periods of winter rainfall in Englandin at least 248 years when records began. It was clear that the limpets and surrounding epilithic communities at Westcombe Beach …

Why Is Eyewitness Testimony So Inaccurate? An Investigation Into Event-Related Potentials And The Recognition Of Familiar And Unfamiliar Faces, Jack Evans

The Plymouth Student Scientist

Eyewitness-testimony is notoriously inaccurate and unreliable. In addition, a body of research has indicated that unfamiliar faces are poorly recognised in comparison to famous or familiar faces. Under the assumption that poor unfamiliar face recognition plays a role in the inaccuracy of eyewitness testimony, the present study sought to use the P300 ERP to provide evidence that unfamiliar face recognition is a factor in the inaccuracy of eyewitness testimony. After showing videos of either busy public places, mock-crime videos, or a film clip, this experiment recorded EEG data from 12 healthy undergraduates in their 20s attending Plymouth University whilst they …

Energy Harvesting In A Diver's Rebreather System, Joseph Ely

The Plymouth Student Scientist

This report investigates the feasibility of energy harvesting using thermoelectric generators in a diver’s rebreather system. The report details research into documented experiments and theory, design and manufacture of an energy harvesting prototype and testing of the prototype to determine its feasibility. The prototype produced a maximum power of 2.5 (mW) which is more than the minimum 50 microwatts of power specified by Avon. It was therefore concluded that energy harvesting within a divers rebreather system is feasibility.

A Palaeoclimatic Reconstruction Of The Cadair Idris Area Of Snowdonia, Using Geomorphological Evidence From Younger Dryas Cirque Glaciers, Bethany Radbourne

The Plymouth Student Scientist

The importance of glacier reconstruction lies in the empirical relationship between glacier mass balance and climate. Small glaciers are particularly sensitive to changes in temperature and precipitation, thus the reconstruction of small palaeoglaciers can provide an understanding of past climatic changes in an area. This study conducts glacier and palaeoclimatic reconstructions for four potential palaeoglaciers at Cadair Idris, southern Snowdonia. Three of these are assigned a Younger Dryas age by referring to published literature, and the fourth is assumed to have existed during an earlier glaciation, possibly reflecting deglaciation from the Last Glacial Maximum (LGM). Schmidt Hammer relative age dating …

Are Children's False Memories Driven By Conceptual Or Perceptual Factors?, Alexandra Hodgson

The Plymouth Student Scientist

Using the Deese/Roediger-McDermott (DRM) paradigm we examined the effects of perceptual (distinctiveness) and conceptual (backward associative strength) factors on the generation of false memories in 5 and 7-year-old children. Participants were randomly assigned to either the perceptually similar (just black or white pictures) or dissimilar condition (alternating black and white with colour pictures). For both conditions, these pictures were also high or low in backward associative strength. We hypothesised that false memories would be influenced by age, perceptual similarity and conceptual factors interacting. Results showed that true memories increased with age. False memories in 5 year olds not only extended …

You Can't Tickle Yourself...Or Can You? The Effect Of A Hypnotic Suggestion On Sensory Attenuation Phenomenon, Shamsideen Yusuf

The Plymouth Student Scientist

The internal motor simulation mechanism is widely believed to generate anticipatory sensory outcomes on the basis of the efferent copy of the motor commands. What is currently unknown is whether the motor prediction mechanism can integrate non-motor inputs such as a hypnotic suggestion in generating sensory predictions. Seventy-two undergraduate students (M=12, F=60) were recruited via Plymouth University participation pool, to undergo a randomised hypnotic suggestion (IV) of either an alien- hand or an alien-foot. The participants were asked to apply tactile stimulation to their left palm (DV) before and after the suggestion and report the tickling sensations. The results revealed …
