The history of translation has been built on the notions that the translator either leaves the writer alone and moves towards the reader (domesticating the text), or leaves the reader alone and moves towards the writer (foreignising the text). These strategies have been called many names, but the translator has always been faced with the choice between domesticating or foreignising the target text. This study considers the options available to a translator when translating the proper nouns and neologisms in a fantasy novel. The translator should not move towards and stand next to the reader to create a target text that is unrecognisable compared to the source text. At the same time, the translator cannot remain next to the writer and thus not change the proper nouns and neologisms to ensure that the target-text readers can understand all – or most of – the potential meanings. If the translator does not move closer to the readers, they cannot have the same experience as source-text readers. This study looks at the translation theories, strategies and procedures that can be applied when translating proper nouns and neologisms used in Terry Pratchett’s Small Gods. It is limited to the study of the neologisms that act as proper nouns, and does not look at other neologisms in the novel. The study identifies translation procedures that retain the meaning potential of the proper nouns and neologisms in the source text in the process of translating them into an Afrikaans target text. It compares the procedures that may have been used by the Dutch translator, by Venugopalan Ittekot, of the novel, Kleingoderij, into Dutch with the procedures that are identified to be used by a translator of the text into Afrikaans. This study identifies the procedures most appropriate to a possible translation of proper nouns and neologisms in Small Gods to Afrikaans in order to retain the meaning potential. The translation procedures that has been identified are addition, cultural adaptation, internationalisation, literal translation, neutralisation, substitution, transference, transliteration and transposition. These procedures can be used to attain equivalence at word level and in such a way that the meaning-potential is retained. / Dissertation (MA) University of Pretoria, 2016. / African Languages / MA / Unrestricted

[pt] Este trabalho se debruça sobre o estatuto de termos metalinguísticos, com especial interesse sobre os nomes próprios. Assim como percebida pelo senso comum, esta classe de palavras se presta com especial docilidade a reforçar uma visão representacionista da linguagem: aqui o nome, ali o nomeado. A recorrente constatação contemporânea da falência dessa visada representacionista convida a reflexões alternativas sobre o vocabulário metalinguístico e sobre os nomes próprios em especial — pois as tentativas de lançar um novo olhar sobre a compreensão da significação linguística esbarram na persistência de um vocabulário que traz consigo marcas da longa hegemonia daquela compreensão de linguagem. A reflexão aqui proposta é desenvolvida a partir dos escritos de Ludwig Wittgenstein e de Samuel Beckett, concentrando-se especialmente nos textos daquele que ficou conhecido como o segundo Wittgenstein e em quatro romances de Beckett — Watt, Molloy, Malone Morre e O inominável. A escolha de tais autores e textos é sensível, por um lado, à fertilidade contemporânea das aproximações entre filosofia e literatura e, por outro, à especial atenção dedicada pelos dois à questão dos nomes próprios. Examina-se um conjunto de passagens relevantes na escrita madura de Wittgenstein, de modo sensível ao que ele diz em Cultura e valor (p. 24): a filosofia realmente deveria ser escrita apenas como uma composição poética. Nos romances de Beckett, por sua vez, focalizam-se tanto as suas singulares provocações onomásticas, quanto momentos metalingüísticosem que personagens endereçam de forma explícita a questão dos nomes próprios. Mostra-se que, tomadas como contra-signos, as escritas desses dois autores, dando a ver a um só tempo a errância dos nomes próprios e o seu paradoxal conservadorismo, acenam com a promessa de caminhos por onde diminuir o abismo que parece ainda separar compreensões intelectuais da linguagem como práxis desprovida de fundamentos e a sua efetiva vivência como tal. / [en] This work focuses on the statute of metalinguistic terms, with special interest in proper names. As perceived by common sense, this class of words is particularly useful to reinforce a representationistic view of language: here the name, there the named. The contemporary and recurring evidence of failure of this representationistic view invites to alternative reflections on the metalinguistic vocabulary and especially on proper names because the attempts to bring a new insight on the understanding of linguistic significance collide with the persistence of a vocabulary marked by a long hegemony of that language comprehension. The argument proposed here is developed from the writings of Ludwig Wittgenstein and Samuel Beckett, especially focusing on the texts of the second Wittengstein and in four Beckett’s novels: Watt, Molloy, Malone Dies and The Unnamable. The choice of these authors and texts has to do with the contemporary richness of approaches between philosophy and literature and also with the special attention both authors dedicated to the question of proper names. It examines a set of relevant texts of Wittgenstein’s mature writings and agrees with his words in Culture and Value (1989, p. 24): philosophy ought really to be written only as a form of poetry. On the other hand, from Beckett’s novels this work focuses both the unique onomastic challenges and metalinguistic moments in which characters explicitly deal with the issue of proper names. It is demonstrated that the writings of these two authors, taken as countersigns showing at the same time the wandering of proper names and their paradoxical conservativeness, beckon with the promise of ways to reduce the gap that still seems to separate intellectual understandings of language as a praxis without basis and its effective experience as such.

We compute the expected numbers of both formal concepts and proper premises in a formal context that is chosen uniformly at random among all formal contexts of given dimensions.

The need for renewable and cleaner sources of energy has made biofuels an interesting alternative to fossil fuels, especially in the case of butanol isomers, with their favorable blend properties and low hygroscopicity. Although C4 alcohols are prospective fuels, some key reactions governing their pyrolysis and combustion have not been adequately studied, leading to incomplete kinetic models. Butanol reactions kinetics is poorly understood. Specifically, the unimolecular and H-assisted tautomerism of propen-2-ol to acetone, which are included in butanol combustion kinetic models, are assigned rate parameters based on the analogous unimolecular tautomerism vinyl alcohol ↔ acetaldehyde and H addition to the double bound of iso-butene, respectively. In an attempt to update current kinetic models for tert- and 2-butanol, a theoretical kinetic study of the unimolecular and H-assisted tautomerism, i-C3H5OH⟺CH3COCH3 and i-C3H5OH+Ḣ⟺CH3COCH3+Ḣ, was carried out by means of CCSD(T,FULL)/aug-cc-pVTZ//CCSD(T)/6-31+G(d,p) and CCSD(T)/aug-cc-pVTZ//M062X/cc-pVTZ ab initio calculations, respectively. For H-assisted tautomerism, the reaction takes place in two consecutive steps: i-C3H5OH+Ḣ⟺CH3ĊOHCH3 and CH3ĊOHCH3⟺CH3COCH3+Ḣ. Multistructural torsional anharmonicity and variational transition state theory were considered in a wide temperature and pressure range (200 K – 3000 K, 0.1 kPa – 108 kPa). It was observed that decreasing pressure leads to a decrease in rate constants, describing the expected falloff behavior for both isomerizations. Results for unimolecular tautomerism differ from vinyl alcohol ↔ acetaldehyde analogue reactions, which shows lower rate constant values. Tunneling turned out to be important, especially at low temperatures. Accordingly, pyrolysis simulations in a batch reactor for tert- and 2-butanol with computed unimolecular rate constants showed important differences in comparison with previous results, such as larger acetone yield and quicker propen-2-ol consumption. In the combustion and pyrolysis batch reactor simulations, using all the rate constants computed in this work, H-assisted reactions are limited because H radicals become abundant once the propen-2-ol has been consumed by other reactions, such as the non-catalyzed tautomerism i-C3H5OH⟺CH3COCH3, which becomes one of the main source of acetone. The intermediate radical (CH3ĊOHCH3) is formed exclusively from tert-butanol, with its concentration in 2-butanol oxidation being smaller because the secondary alcohol is unable to produce the radical directly. In all cases, the intermediate is converted effectively to acetone.

Supersonic jet exhaust plumes produce noise in jet engines, which has been a problem in the aerospace field. Researchers are working on ways to reduce this turbulent mixing noise, with little modification to the engine and nozzle. Prior work has shown that total temperature non-uniformity is a noise reduction technique which introduces a stream of cold flow into the heated jet. This method has been shown to cause changes in the exhaust plume and result in a 2±0.5 dB reduction of peak sound pressure levels. The goal of this work is to reveal underlying changes in the spatial-temporal structure of plume instability and turbulence caused by non-uniform total temperature distributions. Studies have demonstrated several methods of jet noise reduction by modifying the turbulent mixing in the exhaust plume. Large-scale turbulent structures have been shown to be the dominant source of noise in heated supersonic jets, especially over long, streamwise distances. Therefore, a large field-of-view measurement is desirable for studying these structures. Time-Resolved Doppler Global Velocimetry (TR-DGV) with a sampling frequency of 50 kHz is used to collect flow velocity data that is resolved in both time and space. The experiments for data collection were performed on a heated supersonic jet at the Virginia Tech Advanced Propulsion and Power Laboratory. A converging-diverging nozzle with a diameter Reynolds number of 850,000 was used to generate a perfectly expanded, heated flow of Mach 1.5 and a nozzle pressure ratio (NPR) of 3.67. The unheated plume was introduced at the center of the nozzle, with a total temperature ratio (TTR) of 2. Comparison of the mean velocity fields shows that the introduction of the cooler temperature flow in the thermally non-uniform case results in a velocity deficit of about 10% compared to the thermally uniform case. The method of spectral proper orthogonal decomposition (SPOD) was used to reveal the large-scale, coherent noise producing mechanisms. SPOD results indicate that the thermally non-uniform case showed a decrease in turbulent kinetic energy compared to the uniform case at all frequencies. Coherent fluctuations start developing further upstream in the thermally non-uniform case. The addition of the unheated plume results in a disruption in the propagation of the Mach waves from the shear layer into the ambient. The results indicate that the total temperature non-uniformity results in a modified exhaust plume and mean flow distribution at the nozzle exit, compared to that of a thermally uniform flow, which past studies have indicated is a method to reduce jet noise. / Master of Science / Supersonic jet exhaust plumes produce noise in jet engines, which has been a problem in the aerospace field. Researchers are working on ways to reduce this turbulent mixing noise, with little modification to the engine and nozzle. Traditionally, nozzles produce a single stream of uniform temperature flow. This work identifies a method of reducing jet noise, known as thermal non-uniformity. A stream of cold flow is introduced at the center of the nozzle. Applying this method to jet engines can result in quieter aircraft. Large-scale turbulent structures are the dominant noise producing source in supersonic free jets. To further understand the relationship between coherent structures and acoustic jet noise, spectral analysis is used to educe these structures from the flow. This study uses velocity data collected using Time-Resolved Doppler Global Velocimetry (TR-DGV). The study compares the results of a thermally uniform and a thermally non-uniform heated supersonic jet of Mach 1.5. The goal of this study is to determine the effects of thermal non-uniformity on large-scale coherent structures using a modal decomposition analysis known as spectral proper orthogonal decomposition (SPOD). The results from this study show that the thermally non-uniform cases contained less turbulent kinetic energy compared to the thermally uniform cases. Coherent fluctuations start developing further upstream in the thermally non-uniform case. The addition of the unheated plume results in a disruption in the propagation of the Mach waves from the shear layer into the ambient. The results indicate that the total temperature non-uniformity results in a modified exhaust plume and mean flow distribution at the nozzle exit, compared to that of a thermally uniform flow, which past studies have indicated is a method to reduce jet noise.

In applied mechanics it is always necessary to understand the fundamental properties of a system in order to generate an accurate numerical model or to predict future operating conditions. These fundamental properties include, but are not limited to, the material parameters of a specimen, the boundary conditions inside of a system, or essential dimensional characteristics that define the system or body. However in certain instances there may be little to no knowledge about the systems conditions or properties; as a result the problem cannot be modeled accurately using standard numerical methods. Consequently, it is critical to define an approach that is capable of identifying such characteristics of the problem at hand. In this thesis, an inverse approach is formulated using proper orthogonal decomposition (POD) with an accompanying radial basis function (RBF) network to estimate the current material parameters of a specimen with little prior knowledge of the system. Specifically conductive heat transfer and linear elasticity problems are developed in this thesis and modeled with a corresponding finite element (FEM) or boundary element (BEM) method. In order to create the truncated POD-RBF network to be utilized in the inverse approach, a series of direct FEM or BEM solutions are used to generate a statistical data set of temperatures or deformations in the system or body, each having a set of various material parameters. The data set is then transformed via POD to generate an orthonormal basis to accurately solve for the desired material characteristics using the Levenberg-Marquardt (LM) algorithm. For now, the LM algorithm can be simply defined as a direct relation to the minimization of the Euclidean norm of the objective Least Squares function(s). The trained POD-RBF inverse technique outlined in this thesis provides a flexible by which this inverse approach can be implemented into various fields of engineering and mechanics. More importantly this approach is designed to offer an inexpensive way to accurately estimate material characteristics or properties using nondestructive techniques. While the POD-RBF inverse approach outlined in this thesis focuses primarily in application to conduction heat transfer, elasticity, and fracture mechanics, this technique is designed to be directly applicable to other realistic conditions and/or industries.

To accurately model or predict future operating conditions of a system in engineering or applied mechanics, it is necessary to understand its fundamental principles. These may be the material parameters, defining dimensional characteristics, or the boundary conditions. However, there are instances when there is little to no prior knowledge of the system properties or conditions, and consequently, the problem cannot be modeled accurately. It is therefore critical to define a method that can identify the desired characteristics of the current system without accumulating extensive computation time. This thesis formulates an inverse approach using proper orthogonal decomposition (POD) with an accompanying radial basis function (RBF) interpolation network. This method is capable of predicting the desired characteristics of a specimen even with little prior knowledge of the system. This thesis first develops a conductive heat transfer problem, and by using the truncated POD – RBF interpolation network, temperature values are predicted given a varying Biot number. Then, a simple bifurcation problem is modeled and solved for velocity profiles while changing the mass flow rate. This bifurcation problem provides the data and foundation for future research into the left ventricular assist device (LVAD) and implementation of POD – RBF. The trained POD – RBF inverse approach defined in this thesis can be implemented in several applications of engineering and mechanics. It provides model reduction, error filtration, regularization and an improvement over previous analysis utilizing computational fluid dynamics (CFD).

While reading a news article about the upcoming presidential election one day, I noticed a trend. The vast majority of political articles discuss what the federal government should do, but almost never cover what it could do. In elementary school, American children are taught that the Constitution, a 4,543-word document, is the place from which all federal power is derived; but the Constitution says nothing about the regulation of travel, narcotics, or the vast majority of other areas that affect the way we live our daily lives, so where does that power come from? After some preliminary research, I discovered that a great deal of it comes from how the Supreme Court has interpreted two Constitutional Clauses in particular (The Necessary and Proper Clause, and the Commerce Clause) and decided to dig deeper. This thesis is a product of that research. Through a historical overview of Supreme Court jurisprudence on these two clauses, this thesis will reveal that, one case at a time, federal power has gradually expanded through the centuries and shows no sign of slowing, the effect of which is the degradation and potential devolution of American federalism, the backbone upon which this country was founded.
