Utvärdering av skalväggar som byggnadsmetod / Evaluation of double walls as a construction method

Deumic, Emina, Hedin, Madelaine January 2010 (has links)
Granskande av ritningar, tidsplaner och kalkyler för referensprojektet Hus N i Växjö har hjälpt oss kartlägga skalväggars för- och nackdelar. Från intervjuer har vi sedan kunnat se liknelser och skillnader om vad olika yrkesfolk i samma bransch tycker, sedan därifrån dragit slutsatser. Det är inte alltid enkelt att avgöra vilken byggnadsmetod som är att föredra för att projektet ska vara kostnadseffektivt, prefabricerat eller platsbyggd. Faktorer som byggnadens konstruktion, årstid, arbetsmiljö, resurser, tid och kostnad ska ta hänsyns till. Genom att planera bättre, öka förtillverkningen, skapa en bättre samverkan mellan byggherrar, konsulter, entreprenörer, underentreprenörer och materialleverantörer, så anser man allmänt att man kan öka industrialiseringen av byggandet. Då man kan få kortare byggtider och lägre totalkostnader. / Checking of blueprints, time plans and calculations for the reference project house-N in Växjö have helped us to map double walls' advantages and disadvantages. From interviews, we have seen similarities and difference what different people in same sector think, and how they make their conclusions. It is not always simple to decide the preferable building method in order to make the project cost-effective, prefabricated or suite-built. Factors such as the building's frame, season, work environment, resources, time and cost take considerations' to. Through better planning, increase of prefabrication and achieving a better collaboration between developers, consultants, contractors, subcontractors and material suppliers, it is generally considered that it may increase the industrialization of the building. Then procurement of shorter construction times and lower overall costs can be achieved

Electronic Pump Control and Benchmarking of Simulation Tools : AMESim and GT Suite

Joy, Dawn, Sekaran, Karthik January 2011 (has links)
Load sensing pumps in hydraulic system of wheel loaders helps in increasing the energy efficiency of wheel loaders. Present day machines have hydro mechanical load sensing system. After the advent of hydro mechanical load sensing concept, over the years, lots of research has been carried out relevant to electro hydraulic load sensing, trying to control the pump electronically. Currently, Volvo Construction Equipments (VCE) is interested in investigating the possibility of implementing electro hydraulic load sensing system in the wheel loaders. Research works has shown existence of several configurations of electro hydraulic load sensing pumps. Successful simulation results of an electro hydraulic load sensing pump configuration would provide a backing for the proposal of building and testing that configuration of electro hydraulic load sensing pump prototype. Also, the thesis work aims in benchmarking hydraulic system simulation capabilities of AMESim and GT- Suite by simulating the existing hydro mechanical load sensing system in both in both the simulation packages. / The thesis work has been carried out at Virtual Product Development (VPD) division of Volvo Construction Equipments (VCE), Eskilstuna, Sweden.

User Interface Test Automation and its Challenges in an Industrial Scenario

Pradhan, Ligaj January 2012 (has links)
The growing demand for UI test automation has triggered the development of many tools. Researchers and developers have been continuously working to further improvise the existing approaches. If we look at GUI test evolution we can observe a clear progress from manual testing towards complete automation. Numerous approaches have been made to automate the GUI testing process. Record and playback tools, key-word driven methodologies, event flow exploration strategies, model based approaches are continuously evolving with higher level of automation. Similarly, new ideas and strategies to make these tests efficient are also emerging. Optimization of this resource consuming activity is another very important aspect in this area.  Dependencies between different tests can create deadlock scenarios, while running larger test suites. A concept of Ordered Test Suite can be used to cope with such dependencies. Following the Model Driven Architecture initiative by Object Management Group, a new global trend of Model Driven Engineering is creating a big sensation in the field of model based software development. Using the same principle, studies have also been made to automatically generate tests from models. Behavioral models can be made using the model driven approaches and these models can be analyzed to generate tests automatically. This master thesis addresses different approaches made for Graphical User Interface test automation, some optimization issues and solutions, a case study done at a software company to automate User Interface testing and a model driven approach for automatic test case generation.

La Belle au Bois Dormant (The Sleeping Beauty) Tchaikovsky-Pletnev and Stravinsky's Petrouchka: a study of piano transcriptions comprising performances and analyses.

Yang, Vicky (Chia-Yi) January 2005 (has links)
As the costs for mounting opera, ballet and orchestral concerts rise and as their audiences dwindle, piano transcriptions of works orchestrated for such concerts can be a viable way of disseminating the music more widely than if the music was presented only in its original form. With this in mind, it can be argued that piano transcriptions of music originally written for instrumental ensemble is still a viable form of musical expression, because the piano is still the most widely used medium for the performance of art music in the Western world. Transcriptions of instrumental and vocal music expand the listening audience for a composer's music while they also increase the repertoire of music for the piano for both amateurs and professionals. The CD recording has the aim of providing a reference on which to base an appreciation of Pletnev's work. As the orchestral score is quite well known, the differentiation created by Pletnev, and the quality of his work, can be immediately perceived by hearing the execution of his scores and being able to cross reference his reductions with the original score. Timing references for the piano score have been included to further facilitate this cross-referencing. This thesis comprises two parts: 1. A performance CD of Stravinsky's Petrouchka (1922 piano four-hand version) and Tchaikovsky's Sleeping Beauty (1999 solo piano transcription by Mikhail Pletnev). This accounts for 75% of the thesis. 2. An exegesis, analysing selected portions of the orchestral score of Tchaikovsky's The Sleeping Beauty Op.66 and Pletnev's piano transcription suite, prefaced by an overview of piano transcriptions from Liszt to Pletnev. This accounts for 25% of the thesis. The exegesis argues that, while seeking to recreate the colour and drama of Tchaikovsky's orchestral score within the context of a virtuosic piano solo, Pletnev has managed to transcribe Tchaikovsky's score faithfully with minimal alterations.

Petrologia dos diabásios da Região de Ubatuba, SP / Petrology of diabases of Ubatuba region, SP

Fábio Peres da Silva 25 August 2010 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Os diques de diabásio da região de Ubatuba são subverticais e têm orientação preferencial NE-SW, mais precisamente N40-50E, seguindo o trend principal das fraturas na área. Este padrão é concordante com aquele da suíte de alto-TiO2 do Enxame de Diques da Serra do Mar (EDSM) do litoral sudeste do Brasil. As espessuras desses corpos variam de 30 cm a 55 m, tendo, a maioria, entre 1,5 e 8 metros. Subordinadamente, ocorrem diques orientados segundo as direções NW-SE e ENE-WSW. Com relação às formas das fraturas-conduto, a mais comum na qual os diques da área de estudo afloram é a retilínea. No entanto, também foram observadas feições como degraus, pontes, tocos, bifurcações, escalonamento e diques em ziguezague. Os diabásios estudados têm cor preta, por vezes variando em tons avermelhados, de acordo com o grau de alteração. Podem tanto apresentar-se afaníticos quanto finos e, comumente, são porfiríticos, com fenocristais de plagioclásio. Em alguns casos, podem ser observadas amígdalas milimétricas de carbonato de coloração branca. A composição mineralógica desses diabásios é pouco variável, em geral, representada, essencialmente, por plagioclásio, clinopiroxênio rico em Ca (augita) e/ou clinopiroxênio pobre em Ca (pigeonita). Como acessórios podem ocorrer olivina, mineral opaco e apatita. Quanto às características geoquímicas, das 27 amostras selecionadas para análise de elementos maiores e traços, os resultados mostraram que 22 amostras plotam no campo subalcalino e têm afinidade toleítica. A afinidade toleítica da grande maioria das amostras (22 em um total de 27) é corroborada pela presença de quartzo e hiperstênio (e ausência de nefelina) na norma CIPW e, dessa forma, as mesmas podem ser classificadas como quartzo-toleítos. Em três das amostras estudadas, há presença de olivina e hiperstênio normativos e ausência de quartzo, o que as inclui em um grupo de olivina-toleítos. De todas as 25 amostras de diabásio toleítico estudadas, 24 foram inseridas dentro de uma suíte de alto-TiO2 (TiO2 > 2%peso) e apenas 1 foi inserida dentro de uma suíte de baixo TiO2 (TiO2 < 2%peso). O estudo petrológico revela a existência de quatro suítes de alto-TiO2, tendo sido as mesmas discriminadas com base nas razões La/Yb de amostras com o teor semelhante de MgO. Destas, apenas as suítes 2 e 3 tem quantidade mínima de amostras para avaliação de processo evolutivo e os resultados indicam a cristalização fracionada com mudança de assembléia fracionante como processo evolutivo mais provável. A discriminação de fontes mantélicas foi feita exclusivamente com base nas razões entre elementos traços de amostras representativas de líquidos parentais das quatro suítes discriminadas. Os resultados indicam que todas as suítes originaram-se pela fusão de fontes mantélicas enriquecidas, tendo, assim, pelo menos uma contribuição de componentes litosféricos. / The diabase dykes of the study area (Ubatuba region) consist, predominantely, of NE-SW (N40-50E) subvertical bodies which follow the main trend of fractures in the area. This pattern is concordant with that of the high-TiO2 suite of the Serra do Mar Dykes Swarm in southeast coast of Brazil. Subordinately, these dikes follow a NW-SE or a NE-WSW orientation. The thickness of those bodies varies from 0,3 to 55 meters, although most of them have thickness between 1,5 and 8 meters. Regarding the forms of the fracture-conduit, the great majority of the dikes are emplaced within straight fractures. However, features like steps, bridges, stubs, bifurcations, stagger and dykes in zigzag are also observed. The studied diabases have black color, per times varying in red tones, as a reflection of the alteration degree. Most often, diabases are aphanitic or fine grained and, commonly, display porphyritic texture with plagioclase phenocrysts. In some cases, white carbonate-filled milimetric amigdals can be observed. The mineralogical composition of those diabases is little variable, consisting, essentially, of plagioclase, Ca-rich clinopyroxene (augite) and/or Ca-poor clinopyroxene (pigeonite). Acessory minerals are, commonly, olivine, opaque mineral(s) and apatite. Considering the lithogeochemical study, results indicate that, of the 27 samples selected for analysis of major and trace elements, 22 are tholeiitic diabases. The tholeiitic affinity of the great majority of the samples (22 in a population of 27) is corroborated by the presence of quartz and hypersthene (and absence of nepheline) in the CIPW norm, which lead to the classification of these diabases as quartz- tholeiites. In three of the studied samples, the presence of normative olivine and hypersthene (and absence of normative quartz) includes them in an olivine- tholeiite group. Of all the 25 samples of tholeiitic diabases, 24 were accounted to a high-TiO2 suite (TiO2> 2%peso) and only 1 was accounted to a low TiO2 one (TiO2 <2%peso). On the basis of La/Yb ratios and its relations to MgO, it was possible to discriminate four distinct high-TiO2 suites (suites 1, 2, 3 and 4). Of these, only suites 2 and 3 include a minimum amount of samples necessary for the evaluation of evolutionary process, and results indicate, for both suites, that fractional crystallization with change of fractional assembly as a more plausible evolutionary process. The discrimination of mantle sources was made exclusively on the basis of incompatible trace element ratios of samples considered as representative of parental liquids of the four discriminated suites. Results indicate that all four suites were generated by partial melting of an enriched source, which points to the consideration of lithospheric components contribution.

Na porção noroeste, ocorre um corpo com dimensões de aproximadamente 50 km², caracterizado como biotita granodiorito, de granulação grossa, textura inequigranular a porfirítica, metaluminoso à peraluminoso, cálcio-alcalino de alto potássio e magnesiano. Na porção sudeste da área, ocorre um corpo com aproximadamente 100 Km², caracterizado como biotita monzogranito, de granulação grossa, textura equigranular a porfiritica, levemente peraluminoso, cálcico-alcalino de alto potássio e caráter dominantemente ferroso. Datações U-Pb (SHRIMP em zircão) realizadas neste trabalho, mostraram que o biotita monzogranito apresenta uma idade de 1869±10 Ma, o que permitiu incluí-lo como parte da Suíte Intrusiva Matupá, enquanto o biotita granodiorito apresentou idade de 1761±12 Ma, cronocorrelata a idade da Suíte Intrusiva Teles Pires. Entretanto devido as variações composicionais, manteve-se para o granodiorito a denominação de Granito Peixoto. As duas unidades mostram padrões de Elementos Terras Raras com enriquecimento de leves sobre pesados e anomalia negativa de Eu (Lan/Ybn  7,6 a 17,31 e razões Eu/Eu* entre 0,46-0,72 para o biotita monzogranito e Lan/Ybn  7,13 a 29,09 com razões Eu/Eu* entre 0,25-0,40 para o biotita granodiorito). Os elementos-traço para ambos, apresentam anomalias negativas de Ba, P, Ti e Nb indicando uma evolução por fracionamento mineral onde há participação de plagioclásio, apatita e titanita e ou ilmenita, onde a anomalia negativa de Nb está relacionada a herança de placas subductadas. Duas hipóteses são sugeridas para os granitos da região. A primeira supõe que o arco magmático denominado Juruena, inicia com a formação dos granitos da Suíte Intrusiva Matupá (1870 Ma) e prossegue até a idade do granodiorito Peixoto (1761 Ma). A variação composicional gerada no período de 1870 Ma até 1761 Ma é justificada pela presença de uma crosta heterogênea, retrabalhada durante a subducção. A segunda hipótese considera que apenas o monzogranito foi gerado em ambiente de margem continental ativa, num estágio maduro. O granodiorito provavelmente teria se originado em estágio pós-colisional, como resultado de fusão de placa litosférica delaminada, seguida de contaminação crustal. A primeira hipótese têm como base a ausência de evidências de zonas colisionais na região. Entretanto na hipótese 2, considera-se que a ausência de assinaturas colisionais pode estar relacionada à baixa taxa de exumação crustal ou a carência de estudos geológicos. / The analysis of petrographic, geochemical and geochronological data of granites in the region of Peixoto de Azevedo - MT, in the eastern portion of the Alta Floresta Gold Province, led to the recognition of two granitic bodies bounded by major faults and shear zones in the region. In the northwestern portion, a body with dimensions of approximately 50 km ², featured as biotite granodiorite , coarse-grained , porphyritic texture inequigranular to, metaluminous to peraluminous, calc- alkaline high potassium and magnesium occurs. In the southeastern portion of the area, a body with approximately 100 Km ², featured as biotite monzogranite, coarse-grained, equigranular to porphyritic texture, slightly peraluminous, calc- alkaline high potassium and occurs dominantly ferrous character. U- Pb dating ( SHRIMP zircon ) in this work showed that the biotite monzogranite has an age of 1869 ± 10 Ma, which allowed to include it as part of Intrusive Suite Matupá, while the biotite granodiorite had age 1761 ± 12 Ma, cronocorrelata age Intrusive Suite Teles Pires. However due to compositional variations, remained for the designation of granodiorite Granite Peixoto. Both units show patterns of Rare Earth Elements with enrichment of light over heavy and negative Eu anomaly ( Lan / YBN  7.6 to 17.31 and ratios Eu / Eu * between 0.46 to 0.72 for biotite monzogranite and Lan / YBN  7.13 to 29.09 with ratios Eu / Eu * between 0.25-0.40 for the biotite granodiorite ). Trace elements for both present negative anomalies of Ba, P, Ti and Nb indicating an evolution for mineral fractionation where there is involvement of plagioclase, apatite and titanite and ilmenite or where the negative Nb anomaly is related to inheritance subductadas plates. Two hypotheses are suggested to the granites of the region. The first assumes that the magmatic arc called Juruena, begins with the formation of granites Intrusive Suite Matupá (1870 Ma ) and continues until the age of granodiorite Peixoto ( 1761 Ma ). The compositional variation generated in the period from 1870 Ma to 1761 Ma is justified by the presence of a heterogeneous crust reworked during subductio. The second hypothesis considers that only the monzogranite was generated in active continental margin environment, in a mature stage. The granodiorite probably would have originated in post -collisional stage, as a result of fusion of delaminated lithospheric plate , followed by crustal contamination. The first hypothesis are based upon the absence of evidence for collisional zones in the region. However in case 2, it is considered that the absence of collisional signatures may be related to the low rate of crustal exhumation or the lack of geological studies.
