Denna studie har utförts på företaget Camfil Power Systems AB (CFPS) som är en del i Camfil Farr koncernen vilken är ett globalt omfattande företag inom filter- och renluftlösningar. Ett företag som ständigt utvecklas och vill anpassa sina produkter efter den rådande marknaden. Därför håller de just nu på att se över hela sin affärsprocess för att ta fram ett nytt koncept som gör dem mer konkurrenskraftiga. Efter inledande samråd tilldelades en uppgift som var anpassad efter vår utbildning, vilket begränsade sig till att lägga upp ett förslag för att korta genomloppstiden i produktion för renluftslösningen SGT-800. Studien baseras på grundlig genomgång av olika teorier för att kunna lösa den givna uppgiften. Efter påbörjat arbete begränsades det till att bli en ren kvalitativ studie på grund av mätningar på företaget inte var möjligt. Efter avslutade studier kom vi fram till att modularisering och outsourcing kan vara tänkbara lösningar för företaget samtidigt som ständigt förbättringsarbete tillämpas.

There are several methods to predict financial crises. There are also several types of indicators used by financial institutions. These indicators, which are estimated in different ways, often show various developments, although it is not possible to directly assess which is the most suitable. Here, we still try to find what characteristics that industry group has and forecast financial crises In this paper, our data started from monthly of 1977 January to 2008 December in S&P100. We consider Fama-French and Cluster Analysis to process data to make data with same characteristic within a group. Then, we use GARCH type models and apply it to VaR predicting stock turmoil. In conclusion, we found that the group which has high kurtosis value is the key factor for predicting stock crises instead of volatility. Moreover, the characteristics of this industry which can predict stock crises is a great scale. On the other hand, we can through this model to double check the reaction for anticipating. Therefore, people can do some actions to control risk to reduce the loss.

Metal oxides exhibit a wide range of chemical and electronic properties, making them an extremely interesting subject for numerous applications in modern electronics. The primary goal of this research is to develop metal-oxide-based electronic devices, including thin-film transistors (TFTs), resistance random-access memory (RRAM) and planar nano-devices. This research requires different processing techniques, novel device design concepts and optimisation of materials and devices. The first experiments were carried out to optimise the properties of zinc oxide (ZnO) semiconductors, in particular the carrier concentration, which determines the threshold voltage of the TFTs. Thermal annealing is one common method to affect carrier concentration and most work in the literature reports performing this process in a single-gas environment. In this work, however, annealing was carried out in a combination of air and nitrogen, and it was found that the threshold voltage could be tuned over a wide range of pre-determined values.Further experiments were undertaken to enhance the carrier mobility of ZnO TFTs, which is the most important material quality parameter. By optimising deposition conditions and incorporating a high-k gate dielectric layer, the devices showed saturation mobility values over 50 cm2/Vs at a low operating voltage of 4 V. This is, to our knowledge, one of the highest field-effect mobility values achieved in ZnO-based TFTs by room temperature sputtering. As an important type of metal-oxide-based novel memory devices, which have been studied intensively in the last few years, RRAM devices were also explored. New materials, such as tin oxide (SnOx), were tested, exhibiting bipolar-switching operations and a relatively large resistance ratio. As a novel process variation, anodisation was performed, which yielded less impressive results than SnOx, but with a potential for ultra-low-cost manufacturing. Finally, novel planar nano-devices were explored, which have much simpler structures than conventional multi-layered transistors and diodes. Three types of ZnO-based nano-devices (a side-gated transistor, a self-switching diode and a planar inverter) were fabricated using both e-beam lithography and chemical wet etching. After optimisation of the challenging wet etching procedure at nanometre scale, ZnO nano-devices with good reproducibility and reliability have been demonstrated.

In gas turbines, the temperature behind the combustors is the highest, meaning that the blades in the first stage of the turbine require cooling air. This makes the structural blade model very detailed due to the presence of the cooling pattern. For aeromechanical design, one of the first steps is to perform a modal frequency check by using 3d Finite Element models and the Campbell diagram to establish if the design is acceptable with respect to resonance margins. If the 3d detailed geometry (including all the cooling details) is used the model becomes extremely large. In order to perform various loops between structural dynamics and aerodynamics in an early stage, the dynamic model of cooled blades should be simplified. The simplified model should be accurate enough in terms of predicting correct frequencies but much lighter in size.   The objective of this thesis is to perform parametric studies of different 3d simplified cooled turbine blade models. Various models with different geometrical features are created from the history of the CAD software (NX). Different FE meshes are produced in the Hypermesh software and the modal analyses are solved in Abaqus. The results are compared with the fully detailed model. The influence of the cooling features for each test case is summarized and this will be useful for creating reduced order models. Explanation and guidelines with respect to the mesh generation and loading conditions in Hypermesh software are also included in the appendix section.    For quick frequency checks during the intial stages of the design, the solid blade model can be used which has the modal frequencies within 10 percent range from the fully detailed model. The cooling core features that are important with respect to dynamics are cooling matrix, the ribs and the trailing edge cutback which contribute to the stiffness of the blade.

Pepper's Lonely Hearts Club Band, and in the Teatro do Absurdo (The Absurd Theater). We have the art as the expression of the spirit of that time in the development of the human thinking, which we treat here manifested in the daily life of each time. So we intend to close this paperwork showing some aspects that make possible the convergence of all these elements in the XXI century, tracing along the way the consequences of this way of thinking and dealing with the world. / O presente trabalho presta-se a traçar, a estabelecer uma relação entre o pensamento de Francis Schaeffer ao movimento da contracultura; o movimento contracultural da década 60 principalmente relativo aos anos de 67-69 com os beatniks, o Flower Power, Timothy Leary e seus desdobramentos mais marcantes; e, por fim, as expressões contraculturalistas no uso das drogas, no álbum dos The Beatles, Sgt. Pepper's Lonely Hearts Club Band e no Teatro do Absurdo. Tendo a Arte como a expressão do espírito das épocas do desenvolvimento do pensamento humano que tratamos aqui, manifestadas no cotidiano de cada época. Procuramos fechar nosso estudo demonstrando alguns aspectos que tornam possível a convergência de todos esses elementos na produção da cultura do homem do século XXI, traçando, ao longo do caminho, as consequências desta forma de pensar e atuar no mundo.

O trabalho, composto por dois artigos, tem como tema a dimensão social da integração regional, caracterizada pela relação entre direitos sociais e interesses comerciais, com foco no caso do Mercosul. O primeiro artigo realiza uma revisão bibliográfica, sistematizando-a em duas grandes linhas de estudo. Primeiramente, a relação entre comércio e direitos humanos, em particular o direito à saúde, e o potencial da integração regional para a sua efetivação. Em segundo lugar, as interpretações sobre a evolução institucional e conceitual da dimensão social do Mercosul. O segundo artigo apresenta os resultados do estudo empírico do caso das normas do Mercosul-Saúde, orientado pela hipótese de que, em consonância com uma suposta mudança de paradigma, as normas sanitárias teriam migrado da eliminação de barreiras ao livre comércio para a proposição de políticas integradas tendentes a dar efetividade ao direito à saúde dos cidadãos mercosulinos. / This work, consisting of two articles, has as its main theme the social dimension of regional integration, characterized by the relationship between social rights and commercial interests, focusing on the case of Mercosur.
