Abstract:

This paper explores the concept of multigenerational emotional process in Tennessee Williams’s Cat on a Hot Tin Roof. This concept is derived from the psychiatrist Murray Bowen’s theory that is called Bowen family systems theory and it includes eight interlocking concepts: differentiation of self, triangles, nuclear family emotional system, family projection process, sibling position, multigenerational emotional process, emotional cutoff, and societal emotional process. The concept of multigenerational emotional process expands the emotional system from the circle of the nuclear family to a larger circle of grandparents and extended family. Cat on a Hot Tin Roof is the distinctly multigenerational play in Williams’s drama. Cat on a Hot Tin Roof signifies two noticeable generations representing the transmission of the Southern heritage intergenerationally on both emotional and cultural levels.

Abstract:

This study concentrates to analyze Margaret’s character about loneliness that experience by her in Tennessee William’s a Cat on the Hot Tin Roof. Loneliness is unpleasant situation that experience by someone when the one’s desire or ambition is not equivalent in social relationship. Furthermore, the source of the data is telling about someone who experiences loneliness which contains the type of loneliness, effect of loneliness and the effort to overcome from loneliness, consequently the theory of loneliness is chosen. Besides that, this study is qualitative design because the data are collected in the form of words. The data of this study are narrator’s explanations and the character’s utterances related to the loneliness experienced by Margaret and the writer has function as the key instrument in this research. According to the analysis of the drama, the writer has finds the answer of the research problem, that are types and effect of Margaret’s loneliness and Margaret’s effort to overcome or coping loneliness in Tennessee William a Cat on the Hot Tin Roof. There are two types of Margaret’s loneliness, they are emotional and social loneliness. Firstly, Margaret’s emotional loneliness is her unsatisfactory relation with Brick. She does not get intimate relation from Brick. Therefore, she cannot get unpleasant situation from Brick. Secondly, Margaret’s social loneliness, she as a part of Brick’s family is not respected and accepted in the family due to her childless and Brick’s addiction to liquor. Effects of Margaret’s loneliness. She transforms to be rude and frantic, she becomes talkative person, and the last effect is she has much power to be brave person. Margaret’s effort to overcome her loneliness, she tries to understand Brick’s situation and attitude to get attention and more communication with him.

Abstract:

Taking as a starting point Chesterman’s (2009) proposal for an interdiscipline of Translator Studies within a sociological scope, this article discusses the concept of translatorial selfcensorship in light of the 20th-century Portuguese dictatorship. The play Gata em telhado de zinco quente, a translation of Tennessee Williams’ Cat on a hot tin roof, commissioned to Sérgio Guimarães in 1959 by impresario Vasco Morgado, provides sufficient archival material for a debate on the multiple layers of censorship in the target (con)text, with implications for translator agency.

La gata sobre el tejado de zinc caliente (1955) es una de las obras más famosas del dramaturgo norteamericano Tennessee Williams. Premio Pulitzer y premio de la crítica,llevada en 1989 al cine bajo la dirección de Richard Brooks, protagonizada por Paul Newman y Elisabeth Taylor, La gata es una punto de referencia indiscutible en el teatro norteamericano de post-guerra. Sin embargo, La gata también fue una obra problemática en su contexto por abordar directamente el tema de la homosexualidad. En una época de profundas restricciones sexuales y fuerte censura, no podía ser de otro modo. Para su estreno, el directo Elia Kazan le pidió a Williams que realizase modificaciones al texto original, sobretodo en el tratamiento ambiguo de la sexualidad del protagonista. Aunque importante, la homosexualidad es solo uno de los varios elementos del contexto que la obra problematiza. Como señala Williams en una larga acotación en el tercer acto, añadida para la publicación de la versión original, su preocupación fundamental en la obra no es el problema psicológico de un personaje en particular, sino una crisis familiar

Abstract:

A Student Handbook to the Plays of Tennessee Williams provides the essential guide to Williams' most studied and revived dramas. Authored by a team of leading scholars, it offers students a clear analysis and detailed commentary on four of Williams' plays: The Glass Menagerie, A Streetcar Named Desire, Cat on a Hot Tin Roof and Sweet Bird of Youth. A consistent framework of analysis ensures that whether readers are wanting a summary of the play, a commentary on the themes or characters, or a discussion of the work in performance, they can readily find what they need to develop their understanding and aid their appreciation of Williams' artistry. A chronology of the writer's life and work helps to situate all his works in context and the introduction reinforces this by providing a clear overview of Williams' writing, its recurrent themes and concerns and how these are intertwined with his life and times. For each play the author provides a summary of the plot, followed by commentary on: * The context * Themes * Characters * Structure and language * The play in production (both on stage and screen adaptations) Questions for study, and notes on words and phrases in the text are also supplied to aid the reader. The wealth of authoritative and clear commentary on each play, together with further questions that encourage comparison across Williams' work and related plays by other leading writers, ensures that this is the clearest and fullest guide to Williams' greatest plays.

Abstract:

With this thesis I will explore the many challenges that confront a leader on a creative project, the difficulties that prevent open communication, and the discoveries that I will use to serve myself on future projects. Through diligent notes during the multiple months that Cat on a Hot Tin Roof took to produce, I was able to re-create what my experience was and how it benefitted me moving forward. This thesis will document the entire process from play selection, through the final product including the response from the audience. Through this document I will try and highlight, how my own skills were tested, expanded, and seasoned throughout the process. In addition to the study of my own learning, this thesis will highlight the valuable advice that I received from instructors, as well as documenting the implementation of said advice in this university setting. In addition to looking at myself, I also will identify some things that I will be on the lookout for in future creative ventures, both from fellow collaborators, and from institutions. Eventually when this process was in the books, I looked back on the experience fondly, and with a sense of pride. I was able to reflect in the post-mortem phase of the production, and identify room for growth, but above and beyond that identify where growth had occurred during the work, not only in this process, but also in my three-year journey at the University of Massachusetts Amherst.

Abstract:

This thesis is a two-part work. Its components, a written paper and a one-night symposium/film screening event entitled Tennessee Williams: Gender Play in 2015 and Beyond, have been closely coordinated with my dramaturgical research for the February 2015 University of Massachusetts Amherst Department of Theater production of Cat on a Hot Tin Roof. The written inquiry is structured around a chronological, selected American production history of Cat; this history, rendered in a series of three case studies, will (1) synthesize preexisting analyses of Cat’s dramaturgical profile, its impact on American theater, and its position in Williams’s oeuvre; and (2) examine the interplay between this body of scholarship’s primary foci (e.g., gender, sexual identity, and family dysfunction) and the evolving cultural climate in which its subject, Cat, is perennially reinterpreted and restaged. In other words, my thesis reframes Cat as a series of inherently American—and potentially unanswerable—questions posed by Williams to his viewers; it then investigates the artistic and critical responses generated by sixty years of public engagement, or “dialogue,” with those questions. Ultimately, each case study will illustrate my central premise: that the value of Cat on a Hot Tin Roof lies in its ability to resonate, both in production design and reception, with the social, sexual, and domestic challenges of the period in which it is produced.

Abstract:

We study the use of different external heating techniques for startup of a PEM fuel cell initially at room temperature. If a hot liquid is used to heat the fuel cell, the startup time depends on the Reynolds number of the hot liquid flow and also on the convective heat transfer coefficient at the liquid channel/bipolar plate interface. Therefore, apart from the energy required to heat the liquid, additional power is required for the external hot liquid pump. Fuel cell can also be directly heated by using electric heaters. Thin flexible heaters were found to be most suitable for the purpose as they allow the use of thin bipolar plates and reduce the thermal contact resistance at the heater/bipolar plate interface. The thermal mass of the bipolar plates was found to be an important factor affecting the startup time. Hence using materials with lower heat capacities reduces startup time. Embedding a heating element in the GDL reduces the startup time as the thermal mass of the GDLs and MEA is much smaller than the bipolar plate. GDLs with low through-plane thermal conductivities and high in-plane thermal conductivities are able to further reduce the startup time when used in conjunction with a heating element in the GDL.

Full text

Abstract:

The benefits of mechanized welding for pipeline construction are well known, as reflected by the high industrial acceptance and usage of its variations. However, the engineering and qualification costs associated with the preparation of alternative acceptance criteria for typical pulsed and short-circuit MIG (GMAW-P and GMAW-S) girth welds can make the implementation of mechanization too costly and/or time consuming for small projects. A multi-wire welding technology, employing a high-deposition consumable that possesses excellent positional capability, along with paired digitally controlled asynchronous inverter power sources, is presented. Trials were performed on CSA Z245.1 914 mm (NPS 36) OD × 20.4 mm WT Grade 483 heavy wall high strength line pipe. One variant used an 8-head internal welding machine for the root pass, and a conventional single torch short-circuit GMAW hot pass in a compound narrow-groove configuration. A second variant utilized an externally applied controlled short-circuit GMAW-S process for the root pass in a factory-style pipe bevel configuration. Both variants employed fill and cap passes using tandem pulsed gas-shielded flux-cored arc welding (T-FCAW-G/P), using rutile consumables, with the “bug and band” MOW II mechanized welding system. Basic mechanical testing was performed on the first weld variant, along with single-edge notched bend (SENB) crack tip opening displacement (CTOD) tests, and results are presented. A productivity comparison is then shown, using weld data from the second weld variant against alternative processes, showing considerably lower fill and cap pass arc time using the T-FCAW-G/P process. Given the process’s low tendency for the formation of planar discontinuities, the process is appealing for the use of “workmanship” acceptance criteria. With further procedure development and fine-tuning of the process, tandem flux-cored arc welding may prove viable, particularly for “short” pipelines, where the costs of comprehensive engineering critical assessment/fitness-for-purpose weld procedure qualification and associated engineering work aren’t justified; as a higher productivity alternative to single wire flux-cored arc welding for mechanized tie-in welding; as a much higher productivity alternative to SMAW for tie-ins; or with a narrow groove design, mainline applications for longer-distance projects.

Abstract:

Understanding thermal boundary resistance (TBR) is becoming increasingly important for the thermal management of micro and optoelectronic devices. The current understanding of room temperature TBR is often not adequate for the thermal design of tomorrow’s complex micro and nano devices. Theories have been developed to explain the resistance to energy transport by phonons across interfaces. The acoustic mismatch model (AMM) [1, 2], which has had success at explaining low temperature TBR, does not account for the high frequency phonons and imperfect interfaces of real devices at room temperature. The diffuse mismatch model (DMM) was developed to account for real surfaces with higher energy phonons [3, 4]. DMM assumes that all phonons incident on the interface from both sides are elastically scattered and then emitted to either side of the interface. The probability that a phonon is emitted to a particular side is proportional to the phonon density of states of the two interface materials. Inherent to the DMM is that the transport is independent of the interface structure itself and is only dependent on the properties of the two materials. Recent works have shown that the DMM does not adequately capture all the energy transport mechanisms at the interface [5, 6]. In particular, the DMM under-predicts transport across interfaces between non Debye-like materials, such at Pb and diamond, by approximately an order of magnitude. The DMM also tends to over-predict transport for interfaces made with materials of similar acoustic properties, Debye-like materials. There have been several explanations and models developed to explain the discrepancies between the mismatch models and experimental data. Some of these models are based on modification of the AMM and DMM [7–9]. Other works have utilized lattice-dynamical modeling to calculate phonon transmission coefficients and thermal boundary conductivities for abrupt and disordered interfaces [3, 6, 10–13]. Recent efforts to better understand room temperature TBR have utilized molecular dynamics simulations to account for more realistic anharmonic materials and inelastic scattering [14–18]. Models have also been developed to account for electron-phonon scattering and its effect on the thermal boundary conductance for interfaces with one metal side [19–22]. Although there have been numerous thermal boundary resistance theoretical developments since the introduction of the AMM, there still is not an unifying theory that has been well validated for high temperature solid-solid interfaces. Most of the models attempt to explain some of the experimental outliers, such as Pb/diamond and TiN/MgO interfaces [6, 23], but have not been fully tested for a range of experimental data. Part of the problem lies in the fact that very little reliable data is available, especially data that is systematically taken to validate a particular model. To this end, preliminary measurements of TBR are being made on a series of metal on non-metal substrate interfaces using a non-destructive optical technique, transient thermal reflectance (TTR) described in Stevens et al. [5]. Initial testing examines the impact of different substrate preparation and deposition conditions on TBR for Debye-like interfaces for which TBR should be small for clean and abrupt interfaces. Variables considered include sputter etching power and duration, electron beam source clean, and substrate temperature control. The impact of alloying and non-abrupt interfaces on the TBR is examined by fabricating interfaces of both Debye-like and non Debye-like interfaces followed by systematically measuring TBR and altering the interfaces by annealing the samples to increase the diffusion depths at the interfaces. Inelastic electron scattering at the interface has been proposed by Hubermann et al. and Sergeev to decrease TBR at interfaces [19–21]. Two sets of samples are prepared to examine the electron-phonon connection to improved thermal boundary conductance. The first consists of thin Pt and Ag films on Si and sapphire substrates. Pt and Ag electron-phonon coupling factors are 60 and 3.1×1016 W/m3K respectively. Both Pt and Ag have similar Debye temperatures, so electron scattering rates can be examined without much change in acoustic effects. The second electron scattering sample series consist of multiple interfaces fabricated with Ni, Ge, and Si to separate the phonon and electron portions of thermal transport. The experimental data is compared to several of the proposed theories.

Abstract:

Site-specific and on-demand cooling of hot spots in the microprocessors can provide efficient cooling solution, improve its performance and increase its life time by reducing peak temperature and achieving more uniform thermal profile on the chip. Thermoelectric coolers (TEC) have the potential to provide such efficient cooling of hot spots on a chip. We investigate pulse cooling behavior of ultra-thin multiple TEC devices integrated inside the electronic package on the active side of a chip below the heat spreader. Various pulse profiles have been studied to obtain optimal shape of the current pulse in order to efficiently operate TECs considering crucial parameters such as the total energy consumed in TECs, peak temperature on the chip, temperature overshoot at hot spot and settling time during pulsed cooling of hot spots. The square root pulse profile is found to be most effective with maximum cooling and half the energy expenditure in comparison to a constant current pulse. It has been observed that high thermal contact resistances can entirely negate the transient cooling effect of the TECs. We analyze the operation of multiple TECs for cooling spatiotemporally varying hot spots. The analysis shows that the temperature of the hot spots can be retained below a threshold using transient current pulses through the TECs. This underlines the benefits of using multiple TECs for hot spot cooling in order to obtain favorable thermal profile on the chip in an energy efficient way.

Abstract:

Heat-flux measurements are presented for the un-cooled blades of a one-and-one-half stage turbine operating at design corrected conditions with a fully cooled upstream vane row and with rotor disk cavity purge flow. The paper highlights the differences in blade heat flux and temperature caused by uniform, radial, and hot streak inlet temperature profiles. A general discussion of temperature profile migration is provided in Part I, and Part III presents data for hot streak magnitudes and alignments. The heat-flux and fluid-temperature measurements for the blade airfoil, platform, angel wing (near the root), and tip as well as for the stationary outer shroud are influenced by the vane inlet temperature profile. The inlet temperature profile shape can be clearly observed in the blade Stanton Number measurements, with the radial and hot streak profiles showing a greater redistribution of energy than the uniform case due to secondary flows. Hot gas segregation is observed to increase with the strength of the temperature distortion. Measurements for the hot streak profile show a segregation of higher temperature fluid to the pressure surface when compared to a uniform profile. The introduction of vane and purge cooling is found to further accentuate the flow segregation due to coolant migration to the suction surface.

Abstract:

The microstructures and mechanical properties of nitrogen bearing Alloy 690 have been systematically investigated. Alloy ingots with different N addition, range from 38 to 330wt.ppm, were melted using vacuum induction melting (VIM) plus electro-slag re-melting (ESR) double processing techniques. The forged and hot rolled different N content bars were solid solution treated between 1010°C and 1080°C, thermally treated at 715°C for different state mechanical property testing and microstructure study. Microstructure analysis indicated that nitrogen addition to Alloy 690 can effectively refine the solution treated austenite grains. This may be associated with titanium nitrides pinning the grain boundaries and hindering the grain growth during solid solution treatment. More nitrides, which are identified as TiN, were found on the grain boundaries and in the inside of austenite grains with increasing N contents of the alloy. The carbide precipitation at 715°C showed significant difference identified by SEM. At the level of 38, 100 and 220wt.ppm N, the chromium carbide Cr23C6 distribution on the grain boundaries appeared to be semi-continuous; when the N content reached 330wt.ppm, only few discrete type of carbides were observed. The tension testing results at room temperature of different N content alloys proved that both the ultimate tensile strength (UTS) and the yield strength (YS) enhanced about 50MPa when N content was raised from 38 to 330wt.ppm in this alloy; while the corresponding elongation (EL) and reduction in area (RA) adversely dropped about 5%. Room temperature hardness rose with increasing N content, well matched tensile strength. High temperature tension testing results at the range of 900∼1250°C showed that a severely hot ductility dip, representing by the values of the reduction in area (RA), existed in 300wt.ppm and 100wt.ppm nitrogen containing alloys at the lower end temperature range of 950∼1100°C. However, such ductility dip could be improved when the N content was at 220wt.ppm, and completely eliminated at 38wt.ppm N content. At the higher end temperature rang of 1150∼1250°C, the ductility of all 4 nitrogen bearing alloys did not show significant difference, even though the hot ductility of minimum 38wt.ppm N samples was preferable. Nitrogen content did not affect high temperature strength; the UTS values nearly had no change at the same testing temperature with different nitrogen bearing alloys. The carbide precipitation difference of the thermally treated alloy, induced by N addition, may affect Alloy 690 corrosion properties, which needs to be studied in future. The mechanical properties variation both at room temperature and high temperatures of different nitrogen bearing alloys in this study will be certainly beneficial to determine the practical processing routes of Alloy 690.

Abstract:

The application of an incompressible Reynolds Averaged Navier-Stokes solver to cases from the NREL/NASA Ames wind tunnel test is described. Six cases of the NREL PHASE-VI rotor in the upwind configuration under zero yaw and zero degrees tip pitch are computed. Favorable comparison of the computed results with measurements in the form of shaft torque, root moments, spanwise force distributions, and pressure distributions are shown. The good agreement documents the feasibility of 3D CFD computations in connection with prediction of the performance of new rotors. Additionally it is shown how CFD computations can be used to determine the three dimensional effects in rotor flows.

Abstract:

A perforated plate heat exchanger can be made very compact by the reduced perforation size. Hence, it fits to the field where high effectiveness but small size is demanded, i.e., cryogenic applications. The compactness of a perforated plate heat exchanger can even reach that of a cryogenic regenerator. We are developing a compact perforated plate heat exchanger for replacing a low-temperature regenerator. In the compact perforated plate heat exchanger, small perforations (diameter: ∼ 150 μm) were patterned by photo-etching on thin copper plate (75 μm thick). Spacers were made of Kapton film (25 μm thick) or stainless steel plate (30 μm thick). Kapton film spacer is for an experimental heat exchanger which requires convenient disassembly, and stainless steel spacer is for the final product which will be diffusion-bonded. In this type of heat exchanger, stream-to-channel convection heat transfer coefficient is so large that conduction along the plate can rather restrict overall heat transfer rate between cold and hot streams. In order to avoid such conduction-restricted overall heat transfer, 14 strip-shaped channels were formed spirally to reduce effective conduction length and enhance lateral conduction. Transverse bypass among cold or hot stream channels were also adopted to relieve flow mal-distribution. Thermal performance of the heat exchanger was both analyzed and experimented between liquid nitrogen temperature and room temperature. The result shows quite good agreement.

Abstract:

To meet aggressive NOx reduction requirements, a range of NOx reduction strategies are currently available for application to pulverized coal fired furnaces. Utilities must assess the benefits and drawbacks of each viable NOx control technology to develop the best strategy for unit specific NOx control that fits within the utilities’ overall compliance plan. The installation of high capital and operating cost NOx reduction technologies, such as selective catalytic reduction, is cost prohibitive on many units. Lower cost technologies, although not capable of SCR level NOx reductions, can provide a more cost-effective approach and still achieve compliance over the fleet. This paper describes how computational fluid dynamic (CFD) modeling has been utilized by an experienced group of combustion engineers to evaluate and design cost effective NOx reduction strategies applied to a relatively unique PC fired unit, a B&W 150 MW roof-fired furnace. The unit fires bituminous coal through 10 multi-tip burners and is equipped with 10 NOx ports located below the burners. A baseline CFD model was first constructed and the predicted model results were compared with available data including NOx and CO emissions, as well as unburned carbon in fly ash. Upon completion of the baseline model, combustion alterations, including deeper staging, were evaluated. Specific burner adjustments were evaluated to allow for the deeper staging without significantly increasing unburned carbon in the fly ash, CO emissions, or near burner slagging. The CFD model was also utilized to evaluate the impact of water injection. AEP has previously utilized water injection to reduce peak combustion temperatures and thermal NOx formation rates in coal fired units for incremental NOx reductions. It is crucial that the NOx production zones in the downstream portion combustion field be identified, since these regions are most likely to produce NOx that will not be subsequently reduced prior to exiting the furnace. The CFD model was utilized to identify the most appropriate regions for water injection combined with the other combustion alterations. The results showed that NOx emissions could be reduced in this unit by approximately 37% from baseline full load emissions with no associated increase in unburned carbon in the fly ash or furnace exit CO. Burner alterations and water injection equipment based on the CFD model evaluation are currently being installed. Comparisons between the model predictions and the post retrofit performance will be provided.

Abstract:

Abstract This paper describes how faulty thin-film transistors (TFTs) having fragile structures in themselves can be characterized by cross-sectional transmission electron microscopy (X-TEM) through the achievement of pinpoint accuracy in focused ion beam (FIB) etching. We demonstrate X-TEM analysis for faulty TFTs caused by mechanical damages, microvoid in their multilayers and long aluminum whiskers growing from the electrodes. X-TEM specimen were prepared by FIB etching without losing unique structures owing to fragile locations. Cross-sectional bright-field TEM micrographs clearly showed the details of cross sectional structure of fragile location. This pin-point X-TEM is quite helpful to identify faults and to reveal root causes of failures.

Abstract:

The IID seminar titled “Building Profitable and Sustainable Community Owned Connectivity Networks”, was hosted on 31 August 2020 on Zoom Webinar. The 2019 White Paper on science, technology and innovation (STI) recognise the pivotal enabling role of information and communication technologies (ICTs) in realising an inclusive and prosperous information society and knowledge economy. One of the Department of Science and Innovation (DSI)’s key role is to catalyse the digital ecosystem and develop scalable models for community owned connectivity networks to replicate in other areas. Rural areas provide challenging environment to implement communication infrastructure for data and Internet based services, including high cost of network implementation and lack of customer base, low-income streams, highly scattered and low population density. The DSI has thus partnered with the University of Western Cape (UWC), the Mankosi Village community, with support from the Technology Innovation Agency (TIA) to scaleup the Zenzeleni Community Owned Connectivity Networks (COCN). The Zenzeleni COCN has been in existence since 2012 and provides timely, reliable and affordable Wi-Fi connectivity to the remote rural areas of Mankosi and Zithulele in Mthatha. The webinar, facilitated by Ms Ellen Fischat from Story Room aimed to look at how rural and township wireless connectivity models, including Zenzeleni COCN can be scaled-up to increase the number of people connected in the rural settings, more so in light of the COVID-19 crisis. It is evident from the proceedings the need for community networks to provide access to connectivity and also more importantly, what connectivity enables. Subsequent discussions would need to focus on the users and owners of these community networks to understand how their lives have improved through the deployment of the technology. This will shed light of the financial feasibility and benefit.
