Quantitative partielle- oder allgemeine Gleichgewichtsmodelle stellen in der angewandten Ökonomie ein wichtiges Instrument zur Politikfolgenabschätzung dar. Aus wissenschaftlicher Sicht wird an diesen Modellen ihre mangelnde Transparenz sowie ihre Abhängigkeit von empirisch wenig gesicherten Parametern und Annahmen kritisiert. Mittels einer Meta-Analyse werden daher Studien untersucht, welche Politikfolgen der laufenden WTO-Verhandlungen (Doha-Runde) simuliert haben. Als zentrales Ergebnis zeigt sich, dass die erhebliche Varianz innerhalb simulierter regionaler Einkommensveränderungen durch vergleichsweise wenige, ermittelbare Variablen zu einem hohen Anteil erklärt werden kann. Die Ergebnisse der Meta-Regression können daher als Orientierungshilfe bei Vergleich und Bewertung existierender sowie zukünftiger Simulationsstudien dienen.

The wobbling motion of a 60 HP LCS scroll compressor is studied thanks to a multi-body dynamic model of the compressor in this thesis. The wobbling motion is a relative motion that appears between the two scroll elements and which consists in inclining to one side to an the other side as a wheel. The aims of this thesis are to find what are the most wobbling motion influential factors and to define what are the optimum values of these factors to obtained a wanted wobbling motion.

Optimization generally involve picking the optimum solution to a problem considering all the factors or design variables. HOLISHIP (HOLIstic optimisation of SHIP design and operation for life-cycle) is a European Union research project which is a system based approach aimed at developing optimized designs for the future, structure of which is divided into clusters and into several work packages (WP). Structural optimization of RoRo & RoPax vessels pose several challenges due to the unique design features of these type of vessels. This Thesis work concentrates on structural optimization of midship section transverse frame of RoRo & RoPax hulls for minimum weight thus achieving reduction of lightship weight which is one of the major technical requirements during conceptual design phase as part of WP4&WP7 of HOLISHIP project. Rule based tool called ‘STEEL’ by Bureau Veritas is used for the structural & load modeling and further structural analysis of the transverse frame and then optimization loop is established using ‘modeFRONTIER’ and ‘CAESES’ tools to study effect of different design variables. Also the structural optimization loop involving STEEL tool is to couple with a parametric hull in order to enable study of coupled structural analysis for different parametric hull variations. Structural weight is kept as the objective to minimize and design constraints are considered as per applicable Bureau Veritas rules for classification of steel ships. Then surrogate models are generated to replace the optimization loop using Response surface methodology and results obtained with different algorithms like polynomial regression, artificial neural networks etc. are studied further which would reduce complexity associated compared to conventional direct methods

Fermented foods are consumed all over the world and their consumption shows an increasing trend. They play many roles, from preservation to food security, improved nutrition and social well-being. Different microorganisms are involved in the fermentation process and the diversity of the microbiome is high.Fermented foods are food substrates that are invaded or overgrown by edible microorganisms whose enzymes hydrolyze polysaccharides, proteins and lipids to nontoxic products with flavors, aromas, and textures that are pleasant and attractive to the human consumer. Fermentation plays different roles in food processing, including the development of a wide diversity of flavors, aromas, and textures in food, lactic acid, alcoholic, acetic acid, alkaline and high salt fermentations for food preservation purposes, biological enrichment of food substrates with vitamins, protein, essential amino acids, and essential fatty acids and detoxification during food fermentation processing.

Thin films are important in many of the technologies used every day, impacting major markets for energy, medicine, and coatings. Scientists and engineers have been producing thin films on a wide range of surfaces for many decades but now have begun to explore giving these films new and controlled structures at the nanometer scale. These efforts are part of the new horizons opened by the field of nanoscience and impart novel structures and properties to these thin films. This book covers some of the methods for making these nanostructured thin films and their applications in areas impacting on health and energy usage.

Global concern about climate change caused by the exploitation of fossil fuels is encouraging the use of renewable energies. For instance, the European Union aims to be climate neutral by 2050. Biogas is an interesting renewable energy source due to its high calorific value. Today, biogas is mainly used for the production of electricity and heat by a combined heat and power engine. However, before its valorization, biogas needs to be desulfurized (H2S removal) to avoid corrosion and sulfur oxides emissions during its combustion. Biogas can be upgraded (CO2 removal) and used as vehicle fuel or injected into the natural gas grid. In the last 15 years, significant advances have occurred in the development of biological desulfurization processes. In this book with five chapters, the reader can find some of the latest advances in the biogas desulfurization and an overview of the state-of-the-art research. Three of them are research studies and two are reviews concerning the current state of biogas desulfurization technologies, economic analysis of alternatives, and the microbial ecology in biofiltration units. Biogas desulfurization is considered to be essential by many stakeholders (biogas producers, suppliers of biogas upgrading devices, gas traders, researchers, etc.) all around the world.

This book is intended to be a textbook for advanced undergraduate students, graduate students in engineering, and mid-career engineering professionals. It can also be a reference book, or be used to prepare for the Six Sigma Green Belt and Black Belt certifications by organizations such as American Society for Quality. The book focuses on the introduction of the basic concepts, processes, and tools used in Lean Six Sigma. A unique feature of this book is the detailed discussion on Design for Six Sigma aided by computer modeling and simulation. The authors present several sample projects in which Lean Six Sigma and Design for Six Sigma were used to solve engineering problems or improve processes based on their own research and development experiences in engineering design and analysis.
