title: The Role of Thermospheric Neutral Winds in the Mid-latitude Ionospheric Evening Anomalies
Creators: name: Lomidze, Levan
Publisher: name: Utah State University
Year: 2015

description: One of the intriguing features of the F-region ionosphere are anomalous evening enhancements of the electron density over certain mid-latitude sites. The most prominent example of this enhancement is the Weddell Sea Anomaly. Although the evening anomalies have been known for several decades, their generation mechanisms are still under debate and their accurate modeling remains a challenge. In this dissertation, the role of thermospheric neutral winds in the generation of these anomalies is investigated.
Thermospheric winds play an important role in the dynamics of the F-region ionosphere, and, as it will be shown, in the generation of the evening anomalies. However, to date, their reliable estimation remains a challenge. To mitigate this shortcoming, data assimilation models were employed. First, seasonal global maps of F-region peak parameters (NmF2 and hmF2) from COSMIC radio occultation measurements were assimilated into the Global Assimilation of Ionospheric Measurements Full Physics (GAIM-FP) model. The model estimates magnetic meridional winds at low and mid-latitudes. GAIM-FP estimated winds were shown to be in good agreement with independent ground-based wind observations. Next, in order to address the role of neutral wind components in the generation of anomalies, a separate, 3-D physics-based Thermosphere Wind Assimilation Model (TWAM) was developed. TWAM is based on an implicit Kalman filter technique, and combines GAIM-FP magnetic meridional wind data with the equation of motion of the neutral gas to provide the climatology of the thermospheric wind components. The neutral wind components estimated by TWAM were also found to be in close quantitative agreement with independent ground-based wind observations, and were shown to accurately reproduce NmF2 and hmF2 over the anomalies.
To understand the physical mechanism behind the anomalies, the plasma production, loss, and transport processes were analyzed. It was found that, due to the action of the equatorward wind, the evening density maximum forms at altitudes where the recombination rate is relatively small. It was revealed that at this time and altitude, plasma loss due to transport also weakens. As a consequence, the relative role of solar production increases over the net loss process and the electron density enhancement occurs.
Aboriginal society in North West Tasmania : dispossession and genocide
Creators: name: McFarlane, I
Publisher: name: University Of Tasmania
Year: 2023

description: As the title indicates this study is restricted to those Aboriginal tribes located in the North West region of Tasmania. This approach enables the regional character and diversity of Aboriginal communities to be brought into focus; it also facilitates an examination of the unique process of dispossession that took place in the North West region, an area totally under the control of the Van Diemen's Land Company (VDL Co). Issues dealing with entitlement to ownership and sovereignty will be established by an examination of the structure and function of traditional Aboriginal Societies in the region, as well as the occupation and use they made of their lands. Early contact history with the Europeans is examined to demonstrate that there was a real possibility of developing productive relationships with the indigenous inhabitants at the time the VDL Co. took up their land grants. The character of the VDL Co manager Edward Curr, his role in the development of the VDL Co and his harsh treatment of those under his authority, including the Aborigines is also an important area of study. While Company Directors were prepared to countenance the dispossession of the Aborigines and consequent destruction of their culture, Curr was content to preside over their physical destruction. This thesis will demonstrate that Edward Curr persistently ignored instructions from his Directors to the contrary and created, fostered and supported an ethos that encouraged the systematic eradication of the Aboriginal population on allocated Company lands. In 1834, after only eight years under the care of Curr's administration, less than one sixth of the original Aboriginal inhabitants had survived to be taken into exile by the Friendly Mission. Robinson's Friendly Mission provided the main physical contact between the North West Aborigines and Arthur's administration. Thus the activities of the Friendly Mission and its role in removing many of the Aborigines, by force in many cases, is detailed, as is their treatment and condition at the Wybalenna Establishment. The history of the North West Aboriginal tribes will continue by tracing the events and experiences that followed the exile to Flinders Island and Oyster Cove, concluding with the death in 1857 of the last survivor of the North West population. It will be established that the genocide perpetrated against these tribes, was initiated as part of local VDL Co policy, a process exacerbated through colonial administrative expediency and brought to completion by neglect. Finally, there is a brief review of the popular ideologies concerning race, current during the period under study and the extent to which these ideas moulded attitudes and policies relating to Aborigines both in the North West and in general.
title: The Effects of Salmon Availability, Social Dynamics, and People on Black Bear (Ursus Americanus) Fishing Behavior on an Alaskan Salmon Stream
Creators: name: Chi, Danielle K.
Publisher: name: Utah State University
Year: 1999

description: The primary goals of this research were to investigate 3 ecological factors influencing black bear (Ursus americanus) foraging behavior on an Alaskan salmon (Oncorhynchus spp.) stream: fish availability, social dynamics, and human activity. Over 900 observation hours were Jogged at 2 falls from July !-September I 1993-1995; the lower falls were open to public for wildlife viewing, but the upper falls were restricted to research personnel.
In general, black bears responded to differences in fish accessibility on both spatial and temporal scales. All years of the study, 3 indices of bear activity (bear minutes, bear numbers, bout duration) and fish capture rates were significantly higher (all Ps0) at the upper falls where fishing opportunities were more abundant. Furthermore, seasonal variation in black bear density was indicative of fluctuations in fish accessibility: bear numbers were highest midseason when fish appeared more abundant, but decreased towards the end of the summer.
Although many bears fished within 3 to 5 m of one another, the majority of intraspecific interactions (65-75%) were benign as opposed to agonistic with a preponderance of "passive deferrals" where bears detoured around rather than confronted conspecifics. Only 5. 7% of all interactions resulted in reversals or circularity, providing some evidence for a linear dominance hierarchy. The most dominant bears fished where salmon were highly accessible for longer periods of time, therefore capturing more fish than subordinates each year. Of interspecific interactions, black bears were more likely to be displaced when encountering brown bears on the same side rather than opposite sides of the creek.
Of 24 recognized bears, 71% were observed from 75-100% of the time at the upper falls; only 8% (2 females) fished solely at the lower falls. Five of 8 bears that fished exclusively at the upper falls (all large males) appeared wary of researchers upon their arrival. Based on quantile regression analyses, we found that visitor numbers acted as a ceiling on fishing duration of black bears at the lower falls in 1994 and 1995. Furthermore, 2 habituated bears seen frequently at the lower falls spent less time in view (maximum values) as visitor group size increased.

description: We present a MIR coronagraph to target the direct observation of extrasolar planets for SPICA, in which a coronagraph is currently regarded as an option of the focal plane instruments. The primary target of the SPICA coronagraph is the direct observation of Jovian exo-planets. A strategy of the baseline survey and the specifications for the coronagraph instrument for the survey are introduced together. The main wavelengths and the contrast required for the observations are 3.5-27um, and 10^{-6}, respectively.Laboratory experiments were performed with a visible laser to demonstrate the principles of the coronagraphs. In an experiment using binary-shaped pupil coronagraphs, a contrast of 6.7x10^{-8} was achieved, as derived from the linear average in the dark region and the core of the PSF. A coronagraph by a binary-shaped pupil mask is a baseline solution for SPICA because of its feasibility and robustness. On the other hand, a laboratory experiment of the phase induced amplitude apodization/binary-mask hybrid coronagraph has been executed to obtain an option of higher performance, and a contrast of 6.5x10^{-7} was achieved with active wavefront control.Potentially important by-product of the instrument, transit monitoring for characteization of exo-planets, is also described. We also present recent progress of technology on a design of a binary-shaped pupil mask for the actual pupil of SPICA, PSF subtraction, the development of free-standing binary masks, a vacuum chamber, and a cryogenic deformable mirror. Considering SPICA to be an essential platform for coronagraphs and the progress of key technologies, we propose to develop a mid-infrared coronagraph instrument for SPICA and to perform the direct observation of exo-planets with it.

Social class and hospitalizaiton for mental illness
Creators: name: Bonner, Kenneth Ralph
Publisher: name: University of British Columbia
Year: 2012

description: The pioneer study of A. B. Hollingshead and F. C. Redlich, recorded in their book, Social Class and Mental Illness, indicates that social class is related to a number of factors pertaining to mental illness. Subsequent studies prompted by this work have examined some of these factors. All of these investigations were carried out in the United States in various mental health settings. It became our purpose to examine the relevance of these factors in a Canadian mental hospital setting. Three hypotheses were postulated. First, that social class would be related to the type of treatment received in the hospital. Second, that the duration of stay in the hospital would be related to social class. And, third, that the patient's level of improvement upon discharge from the hospital would be related to social class. Routinely collected data from Riverview Provincial Mental Hospital were used to test these hypotheses. No statistically significant relationships were found between social class and of the three dependent variables. However, it was noted that the higher social class levels of psychotics, as measured by the educational index, seemed to receive more electro-convulsive therapy and group therapy than was the case with any other diagnostic category. Possibly this trend could be persued in subsequent studies. Also, duration of stay was not considered to be an important variable because of the relatively short stay of the majority of all persons admitted to the hospital. It was concluded that the definition of treatment was too narrow. Electroconvulsive therapy and group therapy were the most amenable to statistical examination. However, it is widely recognized that milieu therapy is a major form of treatment in Riverview Hospital and therefore, should be included in any consideration of treatment in subsequent studies.

description: We show that the infrared dynamics of string modes dual to $q\bar q$ states within a Dynamical AdS/QCD model of coupled dilaton-gravity background gives the Reggelike spectrum of $f0's$ scalars and higher spin mesons consistent with experimental data. The pion mass and its trajectory were also described with a scale deformation of the metric and a rescaled string mass. The available experimental decay widths of the $S\to PP$ decays provided a complementary check of the proposed classification scheme for$f_0(980)$, $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$ as radial excitations of $f_0(600)$. For $f_0(980)$ we estimated a mixing angle of $\pm 20^o$ with other structures.

description: We take the MSSM as a complete theory of low energy phenomena, including neutrino masses and mixings. This immediately implies that the gravitino is the only possible dark matter candidate. We study the implications of the astrophysical experiments such as PAMELA and Fermi-LAT, on this scenario. The theory can account for both the realistic neutrino masses and mixings, and the PAMELA data as long as the slepton masses lie in the $500-10^6 $TeV range. The squarks can be either light or heavy, depending on their contribution to radiative neutrino masses. On the other hand, the Fermi-LAT data imply heavy superpartners, all out of LHC reach, simply on the grounds of the energy scale involved, for the gravitino must weigh more than 2 TeV. The perturbativity of the theory also implies an upper bound on its mass, approximately $6-7 $TeV.

description: Die Signalrekonstruktion ist immer ein wichtiges Thema, wobei das Kalman-Filter eine am weitesten verbreitete Methode ist. Aber wenn es viele Zustandsgrößen gibt, brauchen wir viele Messungen. Das Compressive-Sensing (CS) ist in letzter Zeit ein sehr beliebtes Thema. Man kann mit dem Compressive-Sensing ein Signal mit sehr wenigen Messungen zu rekonstruieren, aber das Compressive-Sensing hat viele Einschränkungen. Daher kombiniert diese Arbeit das Kalman-Filter und das Compressive-Sensing, um die Anzahl der benötigten Messungen zur Zustands-schätzung zu reduzieren. Erstens schlägt diese Arbeit drei Methoden vor, um die Anforderungen von dem Compressive-Sensing abzuschwächen: dünnbesetzte Änderung, Dimensionreduzierung und Sparse-Coding-Representation. Außerdem schlägt diese Arbeit zwei Methoden zur Fusion der Informationen aus dem Kalman-Filter und dem Compressive-Sensing vor: durch die Kalman-Gleichung und durch die Pseudo-Messungen. Darüber hinaus schlägt diese Arbeit ein iteratives Verfahren zur Verbesserung der Schätzung. Im idealen Fall kann die Schätzung mit dem neuen Verfahren im Vergleich zum traditionellen Kalman-Filter um 70 Prozent verbessert werden. Dann wendet diese Arbeit das Verfahren auf rauschbehaftete und zweidimensionale Signale an und stellt fest, dass das Verfahren die Schätzung im Vergleich zum traditionellen Kalman-Filter um 25 Prozent verbessert. Schließlich analysiert diese Arbeit den Zusammenhang zwischen Fehler und Systemrauschen sowie Messunsicherheiten und kommt zu dem Schluss, dass das Verfahren bei guter Modellierung und schlechten Sensoren deutlich gute Ergebnisse liefert.

description: We introduce a new type of algebra, the Courant-Dorfman algebra. These are to Courant algebroids what Lie-Rinehart algebras are to Lie algebroids, or Poisson algebras to Poisson manifolds. We work with arbitrary rings and modules, without any regularity, finiteness or non-degeneracy assumptions. To each Courant-Dorfman algebra $(\R,\E)$ we associate a differential graded algebra $\C(\E,\R)$ in a functorial way by means of explicit formulas. We describe two canonical filtrations on $\C(\E,\R)$, and derive an analogue of the Cartan relations for derivations of $\C(\E,\R)$; we classify central extensions of $\E$ in terms of $H^2(\E,\R)$ and study the canonical cocycle $Θ\in\C^3(\E,\R)$ whose class $[Θ]$ obstructs re-scalings of the Courant-Dorfman structure. In the nondegenerate case, we also explicitly describe the Poisson bracket on $\C(\E,\R)$; for Courant-Dorfman algebras associated to Courant algebroids over finite-dimensional smooth manifolds, we prove that the Poisson dg algebra $\C(\E,\R)$ is isomorphic to the one constructed in \cite{Roy4-GrSymp} using graded manifolds.

title: Comparison of Optimization Methodologies for Sustained-Yield Groundwater Pumping Planning in East Shore Area, Utah
Creators: name: Takahashi, Shu
Publisher: name: Utah State University
Year: 1992

description: Combined simulation and optimization models, which are helpful for long-term groundwater planning of complex nonlinear aquifer systems, are developed using alternative modelling approaches. The models incorporate a representation of steady-state, quasi-three-dimensional head response to pumping within an optimization . An embedding model which describes exactly the nonlinear flow of an unconfined aquifer is presented. In contrast with the embedding models presented in the Utah State University Ground Water Model, it directly achieves the optimal solution without a "cycling." To address the nonlinearity of the flow system, response matrix models couple superposition with the cycling procedure. Their linear influence coefficients are generated using a modified McDonald and Harbaugh model.
First, these models are tested for a hypothetical, 625 cell, nonlinear aquifer system and compared in terms of computational accuracy and efficiency. All of the models achieve the same optimal solution. The fully nonlinear embedding model attains the same optimal solution regardless of how far the initial guess is from that solution. Thus, global optimality is probably obtained. A predictive program for comparing a priori the embedding and response matrix models in terms of computational size is also developed. This computes the required memory for running each model, an important factor in computational efficiency. It is based on the number of nonzero elements in the matrix of the optimization scheme.
The model most appropriate for a given aquifer and desired management scenarios is dependent upon required simulation accuracy, flow conditions (steady or unsteady) , spatial scale, model computational resources requirement, and the computational capacity of available hardware and software. The linear embedding model coupled with a cycling procedure, as incorporated within a modified version of the USUGWM, is most appropriate for the subject reconnaissance level study of the East Shore Area. Here, the demand for sufficient water of adequate quality is increasing. The underlying aquifer is three-layered, unconfined/confined and is discretized into 4,880 finite-difference cells. To overcome the difficulties of solving many nonsmooth functions describing evapotranspiration, discharge from flowing wells, and drain discharge, a former cycling procedure is improved by optimizing the purely linearized models repeatedly. Using the modified version of the USUGWM, optimal sustained-yield pumping strategies are computed for alternative future scenarios in the East Shore Area.

title: The Influence of Atmospheric Dust and Foliar Leachates on the Chemical Quality of Throughfall in Northern Utah
Creators: name: Parent, Dennis R.
Publisher: name: Utah State University
Year: 1972

description: In the summer of 1971 a research project was carried out in an attempt to determine the influence of dust and leachates on rainfall quality . Open precipitation collectors , collectors under polyethylene screens, collectors under Douglas-fir (Pseudotsuga menziesii) and juniper (Juniperus scopulorum) , and leaf analyses were used to determine the relative effects of these two processes by which chemicals are incorporated into the rainwater . All samples were analyzed for sodium (Na+) , calcium (Ca++), magnesium (Mg++), potassium (K+) , and available phosphorus. Under the trees , sodium concentrations increased as much as three times the amount found in the open, calcium was 13 to 16 times greater, magnesium concentrations doubled, and potassium increased as much as 50 times that which occurred in the open rainfall. Calcium was the only cation studied in which the leaching process was important. Increased chemical loads of all other cations were mainly due to dust adhering to the tree canopy as wind passed through it and later being washed off by rainwater.

description: We construct asymptotically AdS_5 solutions to 5-dimensional Einstein-Maxwell theory with Chern-Simons term which are dual to 4-dimensional gauge theories, including N=4 SYM theory, in the presence of a constant background magnetic field B and a uniform electric charge density ρ. For the solutions corresponding to supersymmetric gauge theories, we find numerically that a small magnetic field causes a drastic decrease in the entropy at low temperatures. The near-horizon AdS_2 \times R^3 geometry of the purely electrically charged brane thus appears to be unstable under the addition of a small magnetic field. Based on this observation, we propose a formulation of the third law of thermodynamics (or Nernst theorem) that can be applied to black holes in the AdS/CFT context. We also find interesting behavior for smaller, non-supersymmetric, values of the Chern-Simons coupling k. For k=1 we exhibit exact solutions corresponding to warped AdS_3 black holes, and show that these can be connected to asymptotically AdS_5 spacetime. For k\leq 1 the entropy appears to go to a finite value at extremality, but the solutions still exhibit a mild singularity at strictly zero temperature. In addition to our numerics, we carry out a complete perturbative analysis valid to order B^2, and find that this corroborates our numerical results insofar as they overlap.

Methods From 10/2013 to 07/2015, 344 patients with an elective TAVI were consecutively enrolled in this prospective multicentric cohort study. Before intervention, sociodemographic parameters, echocardiographic data, comorbidities, 6-min walk distance (6MWD), quality of life and frailty (score indexing activities of daily living [ADL], cognition, nutrition and mobility) were documented. Out of these, predictors for assignment to CR or GR after TAVI were identified using a multivariable regression model. Results After TAVI, 249 patients (80.7 ± 5.1 years, 59.0% female) underwent CR (n = 198) or GR (n = 51). GR patients were older, less physically active and more often had a level of care, peripheral artery disease as well as a lower left ventricular ejection fraction. The groups also varied in 6MWD. Furthermore, individual components of frailty revealed prognostic impact: higher values in instrumental ADL reduced the probability for referral to GR (OR:0.49, p

Quest for identity in Joseph Conrad's fiction
Creators: name: Epp, Harold Bernard
Publisher: name: University of British Columbia
Year: 2012

description: Joseph Conrad regarded life as the pursuit of a dream which gives man a sense of purpose in life. The individual's attempt, through action and communication, to make this dream real to himself and to his fellow men constitutes the quest for identity in Conrad's works. Chapter I explores various aspects of the quest. Because life is a "destructive element", the individual must struggle to justify his existence and make his dream come true. To be successful in this struggle, man needs self-knowledge. This, in turn, requires a commitment to the community. The quest is, therefore, ethical rather than metaphysical. Chapter II is a study of the egoistic dream. The sense of superiority over the rest of mankind causes Jim, Heyst, and Kurtz to dissociate themselves from their fellow men. Consequently, they lack a clear sense of their moral responsibility and of the destructive tendencies in their own nature. Rather than help these individuals to find meaning in life, the egoistic dream becomes the cause of their failure. Chapter 111 concentrates upon the "saving illusion", a sense of self involving a moral commitment to the community. Through involvement, the individual becomes concerned with fulfilling his moral obligation, rather than vindicating an ideal of himself. Therefore, he seeks the self-knowledge which will enable him to guard against defeat. Obedience to the claims of love and conscience in Under Western Eyes, the sense of duty towards the ship in "The Secret Sharer", and the sense of solidarity in “The Nigger of the Narcissus” enable the protagonists in these stories to fulfil their obligation to the community. Finally, Chapter IV deals with Conrad's artistic endeavour as his quest for identity. Conrad's aim was to communicate his truth to the reader. The achievement of his artistic goal required self-knowledge which he, like his characters, acquired in the struggle of life. The hard realities of life become the "terms of his appeal". Conrad's vision of life evokes in his readers the sense of solidarity which testifies to the success of his quest for identity.

description: This study was conducted to gain a better understanding of the seasonal changes of Gleason Elberta peach flower buds at the vii cellular level. Peach buds were obtained from the Howell Experiment Station in Ogden, Utah. Samples were collected at weekly intervals from October 25th, 1971 to March 29th, 1972 . When a killing frost precluded further sampling, the buds were preserved by standard electron microscopic techniques . Thin sections (500 to 700 A) of the cells around the ovarious cavity were examined with a Zeiss EM-9S-2A electron microscope.
From October 25th, 1971 to January 3rd, 1972, more heterochromatin than euchromatin was in the nucleus . After January 3rd, 1972, no heterochromatin patches were observed. Nucleopores were not observed until March 7th, 1972.
Proplastids looked very similar to mitochondria until November 22nd, 1971 when the alignment of the transparent part of proplastids became apparent around the envelope. The number of lipid droplets increased and reached a maximum level near December 6th, viii 1971 then leveled off. A few short cisternae of rough endoplasmic reticulum (RER) were found only in the sample collected on October 25th. From October 25th throush December 27th, short tubular smooth endoplasmic reticulum (SER) was observed near the cell membrane region and only a few Golgi bodies were found, scattered in the cytoplasm. They were in a pre-maturation stage. Starting from December 27th Golgi bodies were in a maturation stage, long sheetlike rough endoplasmic reticulum was noted and lysosomes, presumably pinched from Golgi bodies, were also observed.
On February 22nd, the number of mitochondria as well as Golgi bodies and Golgi vesicles had increased . The number of mitochondria was further increased on February 29th. On March 7th, amyloplasts presumably developed from proplastids were observed.
The results of this work revealed that polysaccharide metabolism was in progress from October 25th to December 27th as indicated by the presence of SER. The presence of lysosomes starting on December 27th suggested that the cell was undergoing intracellular digestion . The increased number of mitochondria and the Golgi bodies observed on February 22nd revealed an increased rate of respiration and the progression of cell wall metabolism respectively. The presence of nucleopores on March 7th would enhance exchange of information between the nucleus and the cytoplasm.

description: In this paper we examine an alternative formulation of the gauge principle in which the emphasis is shifted from the symmetry transformations to their generators. We show that the gauge principle can be entirely reformulated in terms of promoting constants of motion - which generate rigid symmetries - to constraints - which generate gauge symmetries. In our exposition we first explain the basic philosophy on mechanical systems, and then with the help of De Donder--Weyl formalism we extend our scenario also to a field-theoretical setting. To put some flesh on bare bones we demonstrate our method in numerous examples, including the massive relativistic particle, the Nambu--Goto string and relativistic field theory.

title: Developed Guidelines for a Career Next Step High School Placement Center Compared to Existing High School Placement Practices in Selected Urban High Schools in Utah
Creators: name: Wallace, Jimmie B.
Publisher: name: Utah State University
Year: 1974

description: The purpose of this study was to investigate and analyze community X power actors' responses to a questionnaire, in order to gain information to be used in developing Career Next Step High School Placement Center guidelines.
The study was a descriptive research which employed the reputational technique to identify community power actors and the survey technique to gain Information from selected urban schools for comparative purposes.
The reputations! technique surveyed 31 Ogden Community power actors and the survey technique was administered to 26 selected urban high schools in Utah.
Guidelines were developed for the following major areas:

Functions of a Career Next Step High School Placement Center.

People and/or organizations to be employed by a school district to work in a placement center.

Individuals and/ or organizations that should provide a service to students at the center.

Location for a center, individuals to be in charge, and the center's hours

Individuals and organizations to be represented on the advisory council.

Services to students that should be provided by the center.

Analysis of the survey results from the selected urban high schools revealed that:

19 of the responding 24 indicated they had student placement services in their school.

12 of the 19 indicated their school had a Career Next Step Placement Center.

6 of the 19 indicated their school had a counseling and guidance placement service.

One of the 19 schools Indicated they had a cooperative education placement service.

Of the 5 schools that indicated they did not have a placement service at their school, 4 indicated they thought a Career Next Step High School Placement Center would best serve their school's needs.

The remaining one school thought a counseling and guidance placement service would best serve that school.

In comparing the responses from the selected 26 urban high schools to the developed guidelines for a Career Next Step High School Placement Center, from community power actor responses, there were 25 items of difference determined.

description: We perform numerical simulations of clouds in the Galactic Centre (GC) engulfing the nuclear super-massive black hole and show that this mechanism leads to the formation of gaseous accretion discs with properties that are similar to the expected gaseous progenitor discs that fragmented into the observed stellar disc in the GC. As soon as the cloud hits the black hole, gas with opposite angular momentum relative to the black hole collides downstream. This process leads to redistribution of angular momentum and dissipation of kinetic energy, resulting in a compact gaseous accretion disc. A parameter study using thirteen high resolution simulations of homogeneous clouds falling onto the black hole and engulfing it in parts demonstrates that this mechanism is able to produce gaseous accretion discs that could potentially be the progenitor of the observed stellar disc in the GC. A comparison of simulations with different equations of state (adiabatic, isothermal and full cooling) demonstrates the importance of including a detailed thermodynamical description. However the simple isothermal approach already yields good results on the radial mass transfer and accretion rates, as well as disc eccentricities and sizes. We find that the cloud impact parameter strongly influences the accretion rate whereas the impact velocity has a small affect on the accretion rate.

Integrity Analysis and Coercion in Distributed Systems
Creators: name: Hepburn, M
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis presents a new approach to modelling the security and integrity of data in distributed and ad-hoc networks of processes. An annotated type based analysis is introduced which ensures that no contamination will occur between data considered trustworthy and data that may have been corrupted.\ \ A method of performing safe run-time coercion of security properties of data is also presented. This is novel because it enables users to perform run-time coercions of data in a manner that may be statically proven safe.\ \ Both plain networks and dynamic (agent-based) networks are considered. These are modelled as systems of first-order and higher-order pi-calculus, respectively. The higher-order system examined introduces a new notion of trustworthiness dependent on the context in which it is typed or executed. This allows programs with malicious intent to be safely executed when it can be demonstrated that no possibility for interaction with other programs, including the host, is possible. A concept of execution context is introduced to perform this analysis.\ \ In addition, annotated type systems with and without sub-typing are described, and sub ject reduction is shown to hold for all systems considered.\ \ Implementation of the method is demonstrated via type-inference algorithms, and these are shown to be both sound and complete for all systems.

description: When the electroweak action is rewritten in terms of SU(2) gauge invariant variables, the Higgs can be interpreted as a conformal metric factor. We show that asymptotic flatness of the metric is required to avoid a Gribov problem: without it, the new variables fail to be nonperturbatively gauge invariant. We also clarify the relations between this approach and unitary gauge fixing, and the existence of similar transformations in other gauge theories.

Love-death theme in D. H. Lawrence's early novels
Creators: name: Falk, Linda Margaret
Publisher: name: University of British Columbia
Year: 2012

description: The thesis explores the various aspects of the love death theme in the parent-child, man-man, and man-woman relationships in four of D. H. Lawrence's early novels: The White Peacock, Sons and Lovers, The Rainbow, and Women in Love. However, before this theme can be examined, it is necessary to establish, in detail, what Lawrence considers to be the underlying cultural factor determining the destructiveness in the love relationships: the Christian teaching of self-denial. Christianity has led the individual to deny his Self, his distinct personality, his instinctive individuality. He becomes a "sacrificed," "selfless" creature. Lawrence sees modern industrialism, nationalism and education as secular extensions of Christianity: in all of them,the individual no longer counts. He becomes a mere unit in the great machinery of industrialism, in the impersonal institution of nationalism, and in the education system with its falsified Truths and "vulgar authority." A "dissociation of sensibility" has taken place. Individuals have lost the capacity to respond spontaneously with the "whole" man. They have become "not me" creatures. Because modern man has denied Selfhood, the love between man and woman, which should receive first place, is frequently replaced by parent-child love. The woman cannot love and respect the weak man with the destroyed Self. In her desperate attempt to find the fulfillment that she cannot find with her husband, she turns to her children. They become the substitute lovers to which she "sacrifices" herself. By turning to her children, she humiliates her husband and thus further destroys him, as well as herself. And the children, too, become "crippled" as the result of such a parent-child relationship they feel obligated to return the sacrificial love to the parent and thereby rob themselves of love that should find expression elsewhere. Not only does the weak man fail to maintain the love and respect of the woman, but also he frequently fails to establish a wholesome relationship with other men. According to Lawrence, a man must unite with other men for the "purposive, creative activity" of building a world. The weakling has no distinct Selfhood to bring to this man-to-man friendship. In the four novels examined, the love between the man and woman is usually destructive: a form of death occurs for either the man or woman, or both. Frequently they bring a destroyed Self to the relationship and a further destruction takes place. Occasionally, the destruction in the man-woman relationship is a purgation through which the individual becomes free; through destruction he experiences are birth to a capacity for a new, spontaneous love.

description: We study the wave equation on the real line with a potential that falls off like $|x|^{-α}$ for $|x| \to \infty$ where $2 < α\leq 4$. We prove that the solution decays pointwise like $t^{-α}$ as $t \to \infty$ provided that there are no resonances at zero energy and no bound states. As an application we consider the $\ell=0$ Price Law for Schwarzschild black holes. This paper is part of our investigations into decay of linear waves on a Schwarzschild background.

title: An Analysis of Private Land Transfers and Other Factors in Rural Utah Counties During 1969-1971
Creators: name: Snow, Doyle John
Publisher: name: Utah State University
Year: 1975

description: Apparent increases in sales and price of rural land, recent changes in land taxing procedure and proposed land-use legislation have brought forth a number of land questions among legislators, public officials and the general citizenry of Utah. This study is directed at questions pertaining to land purchases and land buyers in rural Utah counties.
A random sample was taken of the land transfer cards on file at the Utah State Tax Commission. Land buyers whose names appeared on the transfer cards and the returned questionnaires were used in the analysis and are the sole basis of the conclusions of the study.
General conclusions from the study were:

Land-use at the time of the transaction was most frequently agricultural or vacant or idle for acreages and was most frequently nonagricultural for lots.

Following the transaction there was a tendency on the part of buyers to change agricultural and vacant or idle land to a different land use.

Buyer characteristics such as annual income, buyer age and residence varied among the regions of the state and were important factors in land transfers.

About 50 percent of the total dollars spent for land parcels included in the sample went for residential land. Land located near city limits, improved or unimproved, averaged the highest price per acre or lot.

The study's conclusions apply only to recorded land transfers on file at the Utah State Tax Commission for the years 1969 through 1971.
