Sled Crash Test System is one of the key elements in todays high safety vehicle designs. In the crash test systems, high speed imaging by high speed cameras is required. For the success of high speed imaging, high speed cameras should be well secured on the sled of the system which is being accelerated to high-g values to simulate vehicle crash. In this study, structural analysis of the high &ndash / g camera support structure for the sled crash test sytem which is available in METU-BiLTiR Center Vehicle Safety Unit is carried out. For the secure connection of the high speed cameras, three different configurations of the camera support structure with different camera positions are analyzed by transient dynamic analysis. The finite element simulations are carried out under the acceleration of 90 g which is the maximum applicable acceleration on the system. After verification of the configurations with the computer simulations, one of the configuration has been tested at the sled test facility of METU-BILTIR Center Vehicle Safety Unit.

Deep drawing operations are crucial for metal forming operations and manufacturing. Obtaining a defect free final product with the desired mechanical properties is very important for fulfilling the customer expectations and market competitions. Wrinkling is one of the fatal and most frequent defects that must be prevented. This study focuses on understanding the phenomenon of wrinkling and probable precautions that can be applied. In this study, dynamic &ndash / explicit commercial finite element code is used to simulate deep drawing process. The numerical experiments are compared with NUMISHEET benchmarks in order to verify the reliability of the finite element code and analysis parameters. In order to understand plastic wrinkling, the effect of blank holder force is investigated. Axisymmetrical numerical models of a cup are investigated with different blank holder forces. Wrinkling instability is illustrated in energy diagrams of the process. Effect of anisotropy on wrinkling is also discussed by comparing isotropic and anisotropic numerical experiments with the material as steel. Different drawbead models, both equivalent and physical, are implied to the problem and results are discussed. Besides numerical analysis, experimental verification is also conducted as conventional deep drawing operation by a hydraulic press. This yields to the ability to understand the effect of blank thickness on wrinkling formation through numerical and experimental analyses. The wave formations of different sized blanks with four different thicknesses are illustrated.

As the Enlightenment took hold in Europe, all aspects of eighteenth-century society felt its effects. Musical tastes, caught in this ideological shift, began to move from the more codified complexity of counterpoint toward the more simplified aesthetic known as galant. Johann Sebastian Bach, now in the most mature phase of a musical career rooted in the contrapuntal style, came under growing public criticism from proponents of galant who were increasingly dismissive of counterpoint as an out-dated compositional method. In 1741, during this time of growing censure, Bach created the wedding cantata BWV 210, O holder Tag erw&uuml;nschte Zeit, based on an earlier cantata but with significant changes that are unique within this oeuvre. Rather than the typical celebratory libretto characteristic of his other wedding cantatas, Bach mounted a strong rhetorical argument in defense of music, deftly combining irony, humour, and pointed barbs to make his point. The rationale for this has not received significant scholarly attention. This dissertation explores the idea that Bach used BWV 210 as a specific personal response to his critics who favoured the changing musical aesthetic of the era, and as a defense of a contrapuntal style cherished by him but no longer valued by many advocates of the galant. This claim is supported through an aggregation of extant research linking the cantata to the circumstances in which it was created. Particular attention is given to the ideological conflict represented in the aesthetic shift of the eighteenth century, and Bach&rsquo;s reactions evident in written documents, his compositions and in his unique synthesis of compositional styles intersecting the aesthetics of his era. The circumstances under which the cantata was written provide context for the significant libretto revisions undertaken to adapt the cantata from its closest known counterpart, BWV 210a. Finally, Johann Scheibe&rsquo;s published criticism against Bach is explored as an important flashpoint for Bach&rsquo;s use of BWV 210 as a musical rebuttal. Not only is a better understanding of a lesser-known cantata achieved, but a glimpse into the mindset of Bach is also realized through the unusually personal response included in BWV 210.

In the fight to reduce carbon emissions, it is easy to see the necessity of reducing energy consumption. Buildings consume a large amount of energy, and have significant potential for energy savings. One tool for realising these potential savings is building simulation. To be able to use building simulation, accurate models for windows are needed. The models include individual layer models, to determine the solar and longwave radiative behaviours, as well as whole-system models to determine heat flows through the various layers of fenestration systems. This thesis looks at both kinds of models for incorporating windows into building simulations. A new network whole-system model is implemented, and integrated into the California Simulation Engine building simulation software. This model is also used as the calculation engine for a stand-alone rating tool. Additionally, a measurement technique used to measure off-normal solar properties of drapery materials, as part of developing shading layer models, is investigated using a Monte Carlo simulation. The network model uses a very general resistance network, allowing heat transfer between any two layers in a complex fenestration system (CFS), whether they are adjacent or not, between any layer and the indoor or outdoor side, or between the indoor and outdoor sides, although this last case is unlikely. Convective and radiative heat transfer are treated using the same format, resulting in increased stability. This general resistance network is used to calculate indices of merit for the CFS using numerical experiments. This approach requires fewer iterations to solve than previous solution methods, and is more flexible. The off-normal measurement technique which was investigated used a sample holder inserted into an integrating sphere. This is a non-standard way of using an integrating sphere, and early analyses did not provide conclusive information as to the effect of the sample holder. A Monte Carlo analysis confirmed the amount of beam attenuation as being 20% for the sample holder used in the experiments. Also con firmed was the effectiveness of dual-beam integrating spheres in correcting for the presence of a sample holder. The stand-alone rating tool which uses the general network framework, incorporates an easy-to-use visual interface. This tool models multiple types of shading layers with no restrictions on how they are combined. Users can easily change any one layer to see the effects of different arrangements. Users may specify any combination of indoor and outdoor ambient and mean radiant temperatures, insolation, and beam/diffuse split.

In current afterburners combustion is stabilized by the high temperature, recirculating region behind bluff body flame holders, such as V-gutters. Blocking the high speed flow with bluff bodies causes a significant pressure drop, and heating the flame holder by the hot combustion product causes a thermal signature, which is a critical problem in a military jet. To reduce these problems, ignition methods using a high frequency (HF) spark discharge, or a radical jet generator (RJG) were developed. The HF discharge ignited and stabilized a flame successfully in a premixed methane-air flow. The electrical power consumption was very small compared to the combustion heat release, as long as the operating velocity was relatively low. However, a theoretical study showed that the ratio of the electrical power consumption to the heat generation by the stabilized flame increases rapidly with increasing flow velocity. For flame stabilization in a high velocity flow, the developed RJG showed much better performance than direct exposure to a plasma. The present study investigated the characteristics of a radical jet produced in a RJG and injected into a main combustor. The limits of flame stabilization by this jet was measured experimentally, and compared to those of bluff body flame holders. The flame holding performance of the radical jet was also experimentally compared to that of a thermal jet. The effect of radicals on flame stabilization was examined using CHEMKIN, and the limit of flame stabilization by the radical jet was estimated for a simple flow configuration using an approximate solution. The results suggest that the reduction of local spontaneous ignition delay time by active species in the radical jet and the longer length of a typical radical jet compared to the dimension of the recirculation zone behind a bluff body increases the maximum velocity at which a flame can be stabilized.

Buscou-se problematizar, nesse sentido, as mudanças propostas pela Reforma Psiquiátrica, à luz da integralidade da assistência e o papel da atenção básica, da ESF frente ao cuidado ao PTM, uma vez que esses compartilham os princípios fundamentais como: vínculo, responsabilização e acolhimento. Portanto, a partir de uma perspectiva crítica, o trabalho abarca as mudanças no âmbito do cuidado ao PTM, realizou-se pesquisa de campo com os profissionais da ESF e equipe gestora da Secretaria Municipal de Saúde e Assistência Social. Assevera-se que foram lançadas algumas contribuições reflexivas sobre o cuidado ao PTM na atenção básica, tendo como referência o materialismo histórico, do qual foram extraídas categorias analíticas que poderão contribuir com a efetivação da assistência na ESF e a organização do trabalho. A partir das análises dos dados coletados, foi possível perceber que os profissionais da atenção básica não realizam o cuidado ao PTM, primam pelo encaminhamento ao serviço de saúde mental de referência e não conhecem os pressupostos da Reforma Psiquiátrica e as mudanças no âmbito do cuidado. / This study focuses attention on the care of Mental Illness Holder – MIH in basic attention programs, particulary in the Family Health Strategy – FHS in the city of Timóteo/MG, as well as, on the indentification of the possibilities and limits that are present in the routine of basic attention professionals on the effectiveness of the attention. A problematization of the new proposals of the Psychiatric Reform on the light of the complete assistance and the role of basic attention of FHS concerning MIH was searched, considering they share the same fundamental principles, such as: the link, responsabilization and reception. Therefore, from a critical perspective, the work covers the changes on the care of MIH and a research with FHS professionals and local Social Service and Health staff was made. Some contributions for reflection about the care of MIH in the basic attention were presented, and analitical categories from the historical materialism were extracted and can contribute in the effectiveness of care at FHS and the organization of the work. With the analysis of the collected data, this study verifies that basic attention professional don’t provide the care to MIH but just send the patients to the mental health service of reference wich don’t know about Psychiatric Reform or about the changes in the field of care.
