The interferometric cantilever displacement detection in non-contact atomic force microscopy (NC-AFM) is in fundamental aspects explored and optimized. Furthermore, the opto-mechanical interaction of the light field with the cantilever is investigated in detail. Cantilevers are harmonic oscillators that are designed to have a high sensitivity for the detection of minute external forces typically originating from tip-sample interaction. In this work, however, the high sensitivity is used for detailed studies of opto-mechanical forces due to the radiation pressure of the light interacting with the cantilever. The interferometer in the NC-AFM setup consists of an optical cavity working similar to a Fabry-Pérot interferometer in combination with a reference interference arm working similar to a Michelson interferometer combining multi-beam interference with a reference beam resulting in a complex superposition of beams forming the interferometric intensity modulation signal. The character of the interferometer can be adjusted from predominant Michelson to predominant Fabry-Pérot characteristics by the optical loss inside the cavity. A systematic approach for accurate alignment, by using 3D intensity maps and intensity-over-distance curves, as well as the implications of deficient fiber-cantilever configurations are explored and the impact of the interferometer configuration on the detection system noise floor is investigated. A new physical property, namely, the Fabry-Perot enhancement factor is introduced that is a direct measure for the light intensity interacting with the cantilever compared to the reference beam intensity reflected back inside the fiber. The quantification of the optical loss yields an exact knowledge of the amount of light interacting with the cantilever that is crucial to understand opto-mechanical effects. The resulting opto-mechanical force varies sinusoidally during the course of one oscillation cycle. It is a key result of this work that the sinusoidal modification of the cantilever restoring force can be described analogue to the restoring force of a pendulum. This results in an observable amplitude dependent frequency shift of the cantilever oscillation, allowing a calculation of the ratio of the opto-mechanical force relative to the cantilever restoring force and thus allows an in-situ measurement of the cantilever stiffness with remarkable precision. Further investigation of the cantilever oscillation yields that other characteristic properties of the oscillation are significantly modified by the opto-mechanical interaction. The observed effective fundamental mode Q-factor drops significantly while the cantilever amplitude response to a certain excitation voltage increases. A discrete numerical model describing the cantilever as a 1D linear chain of mass points is implemented, yielding that the additional opto-mechanical force results in a partial pinning of the cantilever at the edges of the interferometric fringes. Pinning efficiently shifts energy from the fundamental mode to higher modes and modes of a pinned cantilever, resulting in a complex modal structure.

Obesity is a chronic disease that is caused by a number of factors such as diet, genetics, physical inactivity, and poor dietary habits. This research focused on how income affects obesity among a target population in the African American community in Durham, North Carolina (NC). It has been noted that chronic diseases that are diet-related, for example, obesity, diabetes, hypertension, and high cholesterol, affect African Americans disproportionately, especially those who earn low income. Some studies have also reported that those who make higher income have higher rates of obesity. This inconsistency and gap in the literature prompted research on this topic. Therefore, the purpose of this research was to study the relationship between family income and obesity among African Americans. The study sought to address the key factors that contribute to low family income among African Americans in Durham, NC and the ways in those key factors contribute to obesity among African Americans in Durham, NC. This study implored a qualitative approach by using an individual interview method to glean the lived experiences of participants in Durham, NC. Thirty participants were interviewed and themes from the interviews were analyzed. The health belief model was chosen as the theoretical framework for this study to understand the data and explain beliefs, attitudes, and health behaviors. Key results indicated that low family income contributes to obesity. The study contributes to social change by recommending that policy makers advocate for an increase in national minimum wage, encourage educational approaches to prevent obesity, promote good eating habits, and promote adequate physical activity among African Americans.

<p>This research is concerned with CFD modelling of thermal energy storage tanks containing water with submerged phase change materials (PCM). Under appropriate operating conditions, the energy density of this hybrid system can be significantly increased (two to five times) relative to a system containing water only. However, due to low thermal conductivity of phase change materials, the geometry and configurations of the PCM capsules in the tank should be optimized. This research focused on the assessment of flat plate PCM modules submerged in a rectangular water tank. The encapsulation of the PCM within the slender flat plates resulted in a large PCM surface area and a reduction in the internal heat transfer resistance. The water was heated by coils placed at the bottom of the tank. The resulting natural convection currents acted to transfer heat from the hot coils to the PCM modules which were treated as isothermal at the PCM melt temperature. It is concluded that the charge rate of the system increases to 2.8 times by increasing the PCM volume percentage from 2.5% to 15%. However for PCM volume percentages of more than 15%, the area of the PCM became much more than the area of the coil (around 15 times) in a way that the charge rate of the system started to be controlled by the coil. In this stage, the charge rate of the system remained constant, and adding modules to the system only increased the heat capacity of the system. Therefore the charge rate of the system could only increase if the coil surface area was increased. The heat transfer coefficients of the PCM modules and coil tubes were higher than those evaluated by the experimental correlations for natural convection. This was due to the recirculation of the flow in the tank “pumping effect” created by the coil for PCM modules and by the PCM modules for the coil. It was also concluded that superheating of the PCM surface temperature decreases the heat transfer rate to the PCM significantly, and the charge rate of the system varies linearly with the temperature difference between the PCM modules and the coil.</p> / Master of Applied Science (MASc)

The purpose of this study was to evaluate the effectiveness of the Quality of Life~Contribution Model (QOLC) developed by Murrell and Norris (19S3) as a mental health needs assessment technique for the rural elderly. In this field survey method, measures of mental health areas and program targets within each mental health area are compared and prioritized according to their relative contributions to a subjective index of quality-of-life (QOL). An in-home survey of 60 older adults was conducted. Needs were defined in terms of problems, services, and community support and were measured across the following mental health areas: 1) Depression; 2) Organic Brain Syndrome; 3) Alcohol and Drug Abuse; 4) Anxiety; 5) Caregiver Problems; 6) Schizophrenia; and 7) Health Habits. The utility of the QOLC model was evaluated via the descriptive conclusions generated by multiple regression analysis of the sample survey data, with QOL as the dependent variable and the different need measures and mental health areas as the independent variables. A cost analysis was also completed comparing the net total cost of the QOLC with the hypothesized net total cost of a more traditional mental health needs assessment (consisting of a key informant plus a service use statistics component). The results suggest that although the QOLC mental health needs assessment costs more than simpler needs assessment techniques, it can yield important information that can prevent wasteful spending on increased direct mental health services and can also be used to determine the criteria that should be used to segment the target population. / Master of Science

La implantación progresiva de la Industria 4.0 está modificando, progresivamente, los procesos productivos de la industria. Automatizar y digitalizar los procesos está permitiendo la creación de fábricas cada vez más inteligentes, incrementando la utilización de nuevas tecnologías como la robótica, el internet de las cosas (IOT) e incluso la inteligencia artificial para mejorar la eficiencia en la producción, así como la calidad de los productos que fabrican. La industria del calzado, y sobre todo la que se localiza en Europa, busca cómo competir en costes con Asia, tratando de reducir los costes de fabricación. Al mismo tiempo, está permitiendo la incorporación de nuevos materiales más sostenibles, así como técnicas de fabricación más sostenibles y respetuosas con el medio ambiente. Estas fábricas son, paulatinamente, más inteligentes y es necesario manejar el incremento de información, no solo del proceso productivo (registros de producción, indicadores, …), sino también la información digital de los productos que fabrican (geometrías, fichas técnicas, materiales digitales, …). No es una novedad, en la industria del calzado, que se utilicen tecnologías CAD/CAM para el diseño de los zapatos, ya que son tecnologías que se vienen usando desde hace muchos años, pero la digitalización, creciente, de distintos No es una novedad, en la industria del calzado, que se utilicen tecnologías CAD/CAM para el diseño de los zapatos, ya que son tecnologías que se vienen usando desde hace muchos años, pero la digitalización, creciente, de distintos No es una novedad, en la industria del calzado, que se utilicen tecnologías CAD/CAM para el diseño de los zapatos, ya que son tecnologías que se vienen usando desde hace muchos años, pero la digitalización, creciente, de distintos elementos que dependen unos de otros, y que se fabrican en distintas máquinas con distintas tecnologías, hace que sea necesario la unificación de formatos, no solo en los sistemas CAD/CAM sino también en la forma en que se envía esa información a las máquinas. A través de esta investigación se ha buscado dar respuesta a esta consideración mediante el uso de STEP-NC definiendo una plataforma donde se muestran las ventajas que supondría su implantación en el sector del calzado. Por otro lado, los procesos productivos de esta industria, tradicionalmente manufacturera, en la que realizan multitud de operaciones manuales, repetitivas y en las que en muchas ocasiones se utilizan sustancias peligrosas, necesitan mejorar su nivel de automatización. Es en este sentido, se ha trabajado para automatizar las operaciones de pegado que se realizan durante la producción de calzado, en la que se aplica adhesivo y se realiza la unión del corte (parte superior del zapato) y el piso o suela (parte inferior del zapato). En el transcurso de la investigación llevada a cabo se ha desarrollado un prototipo de celda robótica, compuesta por tres robots, que aplica el adhesivo a la suela, para posteriormente manipularla y unirla al corte. Se ha optado por la utilización de adhesivos hot-melt, basados en poliuretano reactivo, novedoso en el sector, que no contienen solventes y son más respetuosos con el medio ambiente. Para la manipulación de los pisos tras la aplicación del adhesivo, ha sido necesario la utilización de dos robots, sincronizando sus movimientos, para el ajuste de estos objetos flexibles al corte.

Im Bereich der Werkzeugmaschinen können Identifikationsmethoden zur Realisierung einer ressourceneffizienten Produktion durch Überwachung prozessrelevanter Parameter beitragen.

<p dir="ltr">Manufacturing in the United States contributes a significant amount of money to its economy. Simultaneously, it consumes nearly one-third of the total energy produced within the nation. Computer-aided technologies have been developed to aid in streamlining the development of products created within the sector. Despite this, energy-efficiency processes are largely ignored by technologies developed by third-party vendors, within the subtractive manufacturing industry. Such benightedness sparked research into the development of mechanistic and data-driven models that attempt to accurately predict energy consumption. Unfortunately, the models largely fail to reflect the processes for which they are supposedly suitable due to poor experimental validation. The variables monitored within the literature are lacking and neglect to account for the inherent complexity of the processes. A model needs to be developed which properly accounts for the complexities associated with CNC machining. The variables such a model employs must account for variations in operations observed during manufacturing, as supplied via the process. The research conducted herein explores the development of an energy-predicting deep-learning model built upon data from data collected during complex CNC machining. Specifically, the model makes predictions by accepting supplemented numerically controlled programs and processing instructions sequentially, via a recurrent neural network layer. Four variants of the model are created to provide insights into the inclusion of supplementary information. Namely, the comparison of monitored material removal variables. The variables are depth of cut, width of cut, material removal rate, and the volume of material removed per NC instruction.</p>

國 立 政 治 大 學 研 究 所 碩 士 論 文 提 要 研究所別：語言學研究所 論文名稱：論台灣華語中的限定與非限定子句的區分 指導教授：何萬順 博士 研究生：何郁瑩 論文提要內容：〈共一冊，20013字，分七章〉 本篇論文藉由三段邏輯論證法推翻漢語沒有限定與非限定子句之分的論證；反之，支持此區分在台灣華語中的有效性。鑑於「時式」的普遍性，表現在構詞方面的限定與非限定區分在綜合型語言當中是顯而易見的。雖然台灣華語缺乏明顯的構詞標記，但此限定與非限定的區分透過句法類目以及句法現象的限制依然成立。此外，我們亦將次劃分子句為補語的動詞進ㄧ步區分為三類─限定補語動詞、非限定補語動詞、雙類動詞。限定補語動詞可同時次劃分有明顯主語的限定子句以及經由代詞刪略現象後無主語的限定子句，而非限定補語動詞僅能次劃分不帶主語的非限定子句。至於雙類動詞，一類從舊有文獻中劃分出來的新類動詞，擁有同時次劃分限定子句與非限定子句的能力。當雙類動詞次劃分限定子句為補語時，有兩個條件必須被滿足：一是情狀動詞的出現，此為必要條件；二是明顯主語的出現，此為充分條件。再者，子句主語的出現與否端視於主要句謂語與子句謂語間的緩衝詞是否出現。在詞彙功能語法的架構之下，情狀動詞的出現之所以為雙類動詞次劃分限定子句為補語的必要條件是由於雙類動詞要求其子句補語擁有「非實現貌」的元素，而此元素便是由情狀動詞所提供。基於本篇論文中強而有力的論述，我們強烈主張此限定與非限定子句的區分在台灣華語中是存在的，甚至普及於全人類的語言。 / This thesis provides robust argumentation via syllogisms so as to deny the argument that the distinction between finiteness and non-finiteness does not exist in Mandarin Chinese; on the contrary, to defend the proposition that this finite vs. non-finite distinction does exist in Taiwan Mandarin. In virtue of the universality of the category tense, the finite vs. non-finite distinction, morphologically manifested in synthetic languages, is taken for granted. Opaque as it is in Taiwan Mandarin, there still exist other ways for distinction, such as constraints on syntactic categories and operations. Furthermore, we re-classify verbs subcategorizing sentential complements into three types—finite-complement verb (FC verb), non-finite-complement verb (NC verb), dual-listing verb (DL verb). FC verbs can subcategorize not only finite clauses with overt subjects, but also those with covert counterparts left after pro-drop processes, while NC verbs can only subcategorize non-finite clauses as sentential complement. As for DL verbs, a neonatal one extracted from the so-called persuade-type verbs in the literature, has the capability of subcategorizing dual sentential complements, namely, finite clauses and non-finite clauses. When DL verbs subcategorize finite clauses as complement, two conditions must be satisfied to ensure the grammaticality. They are the presence of modals and the presence of overt subjects. The former is a necessary condition; the latter is a sufficient condition. Moreover, the presence of embedded overt subjects hinges on the presence of proper buffers between main predicates and embedded overt subjects. In LFG’s framework, the reason for the presence of modals being the necessary condition is that DL verbs require their sentential complements to have the value IRREALIS, which is denoted by modals obviously. On account of the tenable criteria mentioned in this thesis, we assert with confidence that this finite vs. non-finite distinction does exist in Taiwan Mandarin and that this distinction is considered universal.

As the first major study of the portrait artist Bernard Fleetwood-Walker (1893-1965), this thesis locates the artist in his social, political and economic context, arguing that his portraiture can be seen as an exemplar of modernity. The portraits are shown to be responses to modern life, revealed not in formally avant-garde depictions, but in the subject-matter. Industrial growth, the increasing population, expanding suburbs, and a renewed interest in the outdoor life and popular entertainment are reflected in Fleetwood-Walker’s artistic output. The role played by exhibition culture in the creation of the portraits is analysed: developing retail theory affected gallery design and exhibition layout and in turn impacted on the size, subject matter and style of Fleetwood-Walker’s portraits. Emerging, and soon dominant, tabloid newspapers shaped content and language to attract readers, influencing the articulation of the reception of the artist’s work. This thesis also makes a contribution to the regional perspective, demonstrating the temporary co-existence of multiple, heterogeneous, modern art worlds. Throughout the thesis the relevance of economic factors is emphasised, reappraising the Marxist theory of modern art and concluding that a more complex economic description is required to provide a sensitive and insightful analysis of art history.
