Die Fledermaus: Or How I Learned to Stop Worrying and Love the Trim

Watkins, Lillian Casey 01 August 2014 (has links)
AN ABSTRACT OF THE THESIS OF Lillian Casey Watkins, for the Masters in Fine Arts degree in Theater, presented on May 2, 2014, at Southern Illinois University Carbondale. TITLE: DIE FLEDERMAUS: OR HOW I LEARNED TO STOP WORRYING AND LOVE THE TRIM MAJOR PROFESSOR: Wendi Zea In February of 2014, the School of Music and the Department of Theater at Southern Illinois University presented a production of the operetta Die Fledermaus. This thesis is a presentation of the process and final product of the costume design of that production. Die Fledermaus exhibits the best of carnival escapism, with daring disguises, topsy turvy scenarios, opulent scenes and extravagant use of alcohol. This design project was an attempt at capturing that escapism and expressing it through costuming, paying particular attention to detail and trim and actor movement and dance, creating the bubbly, champagne-filled fantasy that is Die Fledermaus. Chapter 1 contains research and analysis of the script, including information about the composer, cultural and historical occurrences that inform the script and previous production history and critical analysis. Chapter 2 focuses on analysis of the characters and their relationships, and how those inform the design of their costumes. The goals that I wished to accomplish with the design and production of the show are covered within Chapter 3. Chapter 4 documents my design process, leading to Chapters 5 and 6, which document the build and production processes, respectively. Chapter 7 is an analysis of the full process and production itself, in regards to the fulfillment of the aforementioned goals. The appendices contain renderings, research, production paperwork and photos.

An investigation on the suitability of layer manufacturing methods for rapid tooling development in investment casting of light metal alloys

Deez, Brent Steven January 2010 (has links)
Thesis (MTech (Mechanical Engineering))--Cape Peninsula University of Technology, 2010. / The research presented in this report focuses on Investment Casting capabilities for light metal alloys in South Africa and forms part of the Advanced Manufacturing Technology Strategy's (AMTS): Light Weight Metals flagship programme. The research is centred on the suitability of rapid prototyping (RP)/Iayer manufacturing (LM) methods to produce patterns for the investment casting of aluminium (AI), magnesium (Mg) and titanium (Ti) alloys, together known as Rapid Investment Casting. Three core RP technologies are investigated namely: Three Dimensional Printing - Drop-on-Bed from Z-corporation, Three Dimensional Printing - Drop-on- Drop from ThermoJet - 3D Systems and Selective Laser Sintering from EOS. Various RP/LM processes are discussed in detail and highlight the technologies selected in this study. A standard benchmark part, adapted from the European project framework FP6, designed and utilised in similar studies is used as the basis for the research. The Investment Casting process is discussed fully and compared to the Rapid Investment Casting, listing both the advantages and disadvantages of the above mentioned methods. In addition a special study has been conducted on investment casting of large components using layer manufactured patterns. This study not only helped to establish and validate the shrinkage value calculated for the aluminium castings but also showed substantial capability lacks in SA foundries to handle this type of components, which are by definition most often of high added value.

Wetenskaplike en tegniese verslagliteratuur : die waarde , ontsluiting en bibliografiese beheer met verwysing na toestande in Suid-Afrikaanse spesiale biblioteke

Lombard, Beatrix Adriana January 1980 (has links)
Die doelstelling van hierdie verhandeling is om te bepaal of die verslag die draer van waardevolle wetenskaplike en tegniese inligting is, of hanteervorms die gebruik van verslae beinvloed, of die ontsluiting en bekendstelling doeltreffend is, en of die verslagliteratuur as inligtingsbron onbekend is. 'n Literatuur- sowel as 'n empiriese ondersoek na die stand van sake in Suid-Afrika is onderneem. Die literatuurondersoek asook die hoe benuttingsintensiteit van verslagliteratuur deur SuidAfrikaanse wetenskaplikes dui ondubbelsinnig die onmisbaarheid van verslae as inligtingsbron ter bevordering van wetenskapsarbeid aan. Dit blyk dat daar nog verwarring bestaan by bibliotekarisse oor die hantering en ontsluiting van verslae. Deeglike kennis van die aard en kenmerke van die verslag en die hantering daarvan blyk noodsaaklik te wees vir doeltreffende inligtingsvoorsiening aan die gebruiker. Aanbevelings word gedoen vir die ontsluiting van klein-tot-medium en groat verslagversamelings tot die effek dat so ver moontlik van rekenaarmatige stelsels gebruik gemaak meet word. Indien dit onprakties is, word die Termatrex of 'n soortgelyke stelsel aanbeveel. / Dissertation (MSc)--University of Pretoria, 1980. / gm2014 / Information Science / unrestricted

Ultra low power cooperative branch prediction

Bielby, Matthew Iain January 2015 (has links)
Branch Prediction is a key task in the operation of a high performance processor. An inaccurate branch predictor results in increased program run-time and a rise in energy consumption. The drive towards processors with limited die-space and tighter energy requirements will continue to intensify over the coming years, as will the shift towards increasingly multicore processors. Both trends make it increasingly important and increasingly difficult to find effective and efficient branch predictor designs. This thesis presents savings in energy and die-space through the use of more efficient cooperative branch predictors achieved through novel branch prediction designs. The first contribution is a new take on the problem of a hybrid dynamic-static branch predictor allocating branches to be predicted by one of its sub-predictors. A new bias parameter is introduced as a mechanism for trading off a small amount of performance for savings in die-space and energy. This is achieved by predicting more branches with the static predictor, ensuring that only the branches that will most benefit from the dynamic predictor’s resources are predicted dynamically. This reduces pressure on the dynamic predictor’s resources allowing for a smaller predictor to achieve very high accuracy. An improvement in run-time of 7-8% over the baseline BTFN predictor is observed at a cost of a branch predictor bits budget of much less than 1KB. Next, a novel approach to branch prediction for multicore data-parallel applications is presented. The Peloton branch prediction scheme uses a pack of cyclists as an illustration of how a group of processors running similar tasks can share branch predictions to improve accuracy and reduce runtime. The results show that sharing updates for conditional branches across the existing interconnect for I-cache and D-cache updates results in a reduction of mispredictions of up to 25% and a reduction in run-time of up to 6%. McPAT is used to present an energy model that suggests the savings are achieved at little to no increase in energy required. The technique is then extended to architectures where the size of the branch predictors may differ between cores. The results show that such heterogeneity can dramatically reduce the die-space required for an accurate branch predictor while having little impact on performance and up to 9% energy savings. The approach can be combined with the Peloton branch prediction scheme for reduction in branch mispredictions of up to 5%.

'n Praktiese teologiese ondersoek na spiritualiteitstipes in eredienste in die Ring van die Paarl(Afrikaans)

Barnard, Pieter Hendrik 07 June 2005 (has links)
This study is based on the presumption that more than one type of Spirituality prevails amongst members of the Dutch Reformed Church in the Circuit of Paarl. From conversations with colleagues, theological articles and books, own experience of services as liturgist and Myers and Briggs personality profiles, it is evident that there is a confusion regarding the identification and management of the various types of Spirituality. In the Paarl Valley, deep rooted in the Afrikaans Culture and Tradition , as in my own congregation the Dutch Reformed Church Suider-Paarl at the foot of the Afrikaaans Language Monument, there is a search for and a need of a responsible rejuvenation regarding church services. The surrounding contexts and influences can never be removed from certain spiritual types of which members have a deep need. My friends, family and congregation members who were devoted members of the Dutch Reformed Church, have either left the church completely or found a home with other denominations with other types of Spirituality. As a young minister I find it disturbing that large numbers of my age group of 20-35 years have left the Dutch Reformed Church. Since 1996 the Paarl Circuit has lost 4000 members, notwithstanding the fact that the Paarl is regarded as a demographic point of growth in the Western Cape. In surrounding renascence congregations outside the reformed creed, the services are filled with members who were raised within the reformed creed. Post-modern man apparently does not pay attention to theological differences between churches, but preferably respond to any congregation with a certain type of approach and Spirituality. If this is the case, it bodes no well for the Dutch Reformed Church. It will inevitably lead to the impoverishment of services and religious communication. It could also lead to the partial disfunctioning of the services and the homily. Be it true that only one type of spirituality is provided for, with occasional variations, one wonders what the reason is for this. Why do Dutch Reformed ministers cling to a specific Spirituality? Is it because they are satisfied with the content of the "Message", but the atmosphere of Spirituality that exists during the service doesn't matter much? Does it perhaps demand too much work and preparation? It is obvious that a problem exists that must be taken into account. The crux of the research can be summarized as follows: <ul> <li>--- There is a supposition that a problem exists regarding the Spirituality types prevalent in the Dutch Reformed Church, especially in the Paarl Circuit and the personal preference of the members for a specific Spirituality. (Chapter 1)</li> <li>--- A basic theory concerning Spirituality types must be formulated. (Chapter 2)</li> <li>--- The Spirituality types in the Paarl Circuit must be empirically researched. (Chapter 3)</li> <li>--- An adjusted practice theory must be proposed which can lead to an adjusted ministry practice. (Chapter 4)</li> </ul> From the above discussion it is clear that the point of departure in this changed context of the essence of ecclesiasticism, but more specifically the divine service, is confronted by a new challenge. Members are in search of a more effective communication of the Gospel in the context in which the church finds itself today, but, more specifically so, as it appears in the context of the Paarl Circuit.

Technologie lití vysokotlakých odlitků a vlivy působící na jejich kvalitu / Technology of high pressure die-castings and influences having effect on their quality

Štipl, Pavel January 2014 (has links)
This diploma thesis deals with the technology of high pressure die casting and especially influences having effect on their final quality. The aim of this thesis is to design the measures to convert casting of the cylinder for chainsaw into the serial production. The thesis contains a description of the production of castings by technology of high pressure die casting, theoretical analysis of the factors with effects on their final quality and practical description of the conversion casting of cylinder for chainsaw into the serial production. The problem of converting to serial production has been solved by several samplings and final test series. Part of each sampling is analysis of defects and design of measures leading to elimination or at least minimization of such defects. On the basis of the production process has been successfully optimized and casting of the cylinder for chainsaw was successfully converted into the serial production. The results of this work also allowed for a smooth conversion into the serial production of another type of cylinder, manufactured by company MOTOR JIKOV.

Misdaad in die nywerheid. 'n kriminologiese ondersoek

Kruger, Jan Johannes Lewis January 1979 (has links)
Aangesien misdaad in die handel- en nywerheid in die jonste tyd in omvang toeneem, het by die ondersoeker die begeerte ontstaan om vas te stel wat die aard, omvang en die gevolge van misdaad, o.a. winkeldiefstal en gapsery in die privaatsektor is. Voorts is klem gele op die basiese vereistes van sekuriteit asook die daarstelling en gebruik van die beskikbare fisiese beveiligingstelsels. In die laaste plek is aangedui watter rol sekuriteitspersoneel ten aansien van sekuriteit in die handel en nywerheid speel. In die 600 handels- en nywerheidsondernemings wat in die ondersoek betrek is, is 23 052 misdade gepleeg waarvan 18 700 (81,12%) diefstal is. Die ander misdade is bedrog, vervalsing, eiendomsbeskadiging, geweldpleging, aanranding, huisbraak (inbraak) dobbelary en die gebruik van dagga. In totaal is 17 713 van die 23 052 misdade deur die werknemers gepleeg. Twee-en-tagtig persent (14 434) is diefstal en is hoofsaaklik deur die nieblanke rassegroep gepleeg. Die meeste werknemers, naamlik 10 396 (58,69%) wat oortree is tussen die ouderdomme 17 en 25 jaar. Dit is gedurende die leeftyd dat mense tot die beroepsarbeid toetree en dikwels vanwe~ onoordeelkundige besteding van hul verdienste nie die mas kan opkom nie en dan van ongeoorloofde metodes gebruik maak om die soms karige inkomste aan te vul. Namate die ouderdom styg, in die mate neem misdaad af. Die boonste bestuur tree nie deurgaans konsekwent op teen mense wat van hul eiendom steel nie. Die redes is die volgende : In die eerste plek is hulle nie bereid om ter wille van minder ernstige oortredings kosbare ure in die howe deur te bring nie. In die tweede plek tree hulle meer simpatiek op teen die vroulike geslag as teenoor die mans. Laastens word jeugdiges wat oortree eerder aan hul ouers as aan die polisie oorhandig aangesien die boonste bestuur jeugoortreders saver moontlik van die howe probeer we~hou ten einde nie hul toekoms daardeur te benadeel nie. Winkeldiefstal en gapsery is ~ misdaad wat in die jongste tyd vir veral die kleinhandelaars, heelwat hoofbrekens besorg. Die meeste oortreders is werknemers tussen die ouderdomme 17 en 25 jaar. Nie minder nie as 53,40 persent (4 514) val in die ouderdomsgroep. Net 2 jeugdiges tussen 7 en 16 jaar is aan die polisie uitgelewer terwyl die res aan hul ouers oorhandig is. Slegs 4 754 werknemars wat hul werkgewers besteel is aan die polisie uitgelewer terwyl 9 580 nie vervolg is nie. Ten aansien van die buitestaanders is die situasie ietwat anders. In totaal het 2 591 winkeldiewe en gapsers met die gereg gebots teenoor 1 575 wat nie in die hande van die gereg geval het nie. Winkeldiefstal en gapsery het tot gevolg dat die 600 ondernemings R1 656 46o per jaar as onvoorsiene verliese afskryf. Dit is ~ bedrag wat van die verbruikerspubliek verhaal moet wod. die gevolg is dat pryse onnodig die hoogte inskiet met onvermydelike stimulasie van inflasie en benadeling van die landsekonomie. Dit het nodig geword dat elke ondernemer sy eiendom self beskerm en beveilig. Gebruikmaking van die beskikbare fisiese beveiligingstelsels soos dief- en brandalarmstelsels, geslotebaantelevisie, eenrigtingspie~ ls, interkommunikasiestelsels, sekerheidsheinings, sekerheidsbeligting, ens. sal die sekuriteitspersoneel in staat stel om op ~ doeltreffende wyse handels- en nywerheidseiendom te beveilig. Om dit moontlik te maak moet daar noue samewerking tussen die sekuriteitshoof en die boonste bestuur wees. Dit op sigself bring mee dat die boonste bestuur sekuriteitsbewus moet wees. 'n Verliesbeheerstelsel met sekuriteit as basis, behoort die boonste bestuur in staat te stel om daagliks te bepaal of die ondernemings suksesvol funksioneer al dan nie. Indien hulle daadwerklik in die verband optree, behoort deeglik opgeleide sekuriteitspersoneel met behulp van die beskikbare fisiese beveiligingstelsels dit vir die misdadiger bykans onmoontlik te maak om die handel en nywerheid te beroof. / Thesis (DPhil)--University of Pretoria, 1979. / gm2014 / Anthropology and Archaeology / unrestricted
