Robert Musils Die Verwirrungen des Zöglings Törleß handelt von der Entwicklung eines Kadetten angesichts des grausamen Missbrauchs eines anderen Jungen Basini. Dieser Aufsatz analysiert die protofaschistischen Eigenschaften von Haupttätern Reiting und Beineberg, sowie die ästhetische und apolitische Haltung von Törleß gegenüber diesen Verletzungen. Indem dieser Roman eine geschichtliche Interpretation der Zeit erlaubt, muss die „verbesserte“ Position der erwachsenen Hauptfigur, deren Beschreibung vom Erzähler die Handlung unterbricht und einfärbt, als apolitisch und kritisch gesehen werden.

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 machines, where theories as “OEE” (overall equipment efficacy) should be illuminated and analyzed. The theory of “Single Minute Exchange of Die” is also presented. The method used in this project is mostly based on qualitative studies but also quantitative studies are presented. Information has been gathered from Willo Maskin ABs own calculations, the university library of Växjö and electronical sources. The studies have been made through observation and notes of the production process at the workplace. Routines have been checked and discussions with people involved in the process have been passed. The observation also included machine stand still measurement and OEE calculations. The measuring for each machine under a time period shows the lack in the production progress and the methods used. The results show that the machine adjustment is the part of the process that requires the most production time. Discussions with machine operators prove that a lot of them don’t know how to handle new machines. However, the machines work very efficient when they work. It takes short adjustments and further education of operators to increase the availability. The introduction of different production follow-up systems is necessary to be able to measure, and in a long term even reduce the reasons of standstill.

The central goal of this research is to quantitatively characterize the relationships between processing, microstructure, and mechanical properties of important high-pressure die-cast (HPDC) Mg-alloys. For this purpose, a new digital image processing technique for automatic detection and segmentation of gas and shrinkage pores in the cast microstructure is developed and it is applied to quantitatively characterize the effects of HPDC process parameters on the size distribution and spatial arrangement of porosity. To get better insights into detailed geometry and distribution of porosity and other microstructural features, an efficient and unbiased montage based serial sectioning technique is applied for reconstruction of three-dimensional microstructures. The quantitative microstructural data have been correlated to the HPDC process parameters and the mechanical properties. The analysis has led to hypothesis of formation of new type of shrinkage porosity called, gas induced shrinkage porosity that has been substantiated via simple heat transfer simulations. The presence of inverse surface macrosegregation has been also shown for the first time in the HPDC Mg-alloys. An image analysis based technique has been proposed for simulations of realistic virtual microstructures that have realistic complex pore morphologies. These virtual microstructures can be implemented in the object oriented finite elements framework to model the variability in the fracture sensitive mechanical properties of the HPDC alloys.

High Pressure Die Casting (HPDC) is low-cost technique for the mass production of complex, non-ferrous parts. Despite its benefits such as dimensional accuracy, surface quality and high production rate / some mechanical drawbacks limit use of HPDC in production of critical parts especially under dynamical loads. This study aims to improve impact resistance and surface hardness of die cast parts by means of tool steel inserts. These inserts act as a barrier between the impactor and die casting alloy, in order to avoid surface deformation and reduce stress localization which leads crack formation. Except the impact surface, whole insert is embedded into the die casting alloy by placing them on specially machined die casting molds prior to the metal injection. The mentioned method was evaluated by mechanical test and micro-examinations which were applied on AISI D2 tool steel inserted A518.0, A413.2 and Zamak5 alloy samples. To see the effect of inserts on energy absorbance under single destructive loads, both monolithic (conventional) and inserted (produced by mentioned technique) samples were subjected to Charpy impact test. In order to observe its behavior under non-destructive, cyclic, low velocity impacts / a dedicated real rifle part was produced by this method and tested in the real service loads. Explicit Finite Elemental Analysis was also carried out to understand how the inserts increases the energy absorbance and protect the die cast body by simulating both destructive and non-destructive impact loads. In addition to these, micro-examinations were also conducted especially on insert-die casting alloy interface for chemical and physical interactions, defects and stability. In regards of experimental findings, mechanical feasibility of the method was achieved. It was proved that steel inserts improve energy absorbance, stress distribution and impact-surface hardness of die cast products.

Aus der Truppe der Beiträger, die überwiegend dezimalklassifikatorische Beiträge lieferten, gab Magda Heiner-Freiling, Die Deutsche Bibliothek, Frankfurt, einen Sachstandsbericht zum Projekt „DDC Deutsch“ und eine Vorausschau auf die zu erwartenden Dienstleistungen. Festzuhalten ist an dieser Stelle nur soviel, daß die Sachgruppen der Deutschen Nationalbibliografie seit Jahrgang 2004 auf DDC umgestellt sind; damit wurde unsere laufende Nationalbibliografie von einer hausgemachten Systematik in eine international gebräuchliche Klassifikation überführt. Dies entsprach auch der Empfehlung, die im Jahre 1998 von einer Expertenkommission des damaligen Deutschen Bibliotheksinstituts gegeben wurde, die überwiegend mit Mitgliedern der Gesellschaft für Klassifikation besetzt war.
