2. 1. Simulation based design : structural optimization at early design stages

   Author : Marcus Redhe; Linköpings universitet; []
   Keywords : ;

   Abstract : The aim of this thesis is to evaluate and develop different modelling tools which can be used in the vehicle crashworthiness design process. These tools will improve the understanding of the vehicle behaviour and thus improve the crashworthiness of the vehicle. READ MORE

4. 2. Liquid Chromatography Coupled to Mass Spectrometry : Implementation of Chemometric Optimization and Selected Applications

   Author : My Moberg; Jonas Bergquist; Karin E. Markides; Dan Bylund; Douglas B. Kell; Uppsala universitet; []
   Keywords : Analytical chemistry; liquid chromatography; mass spectrometry; tandem mass spectrometry; electrospray ionization; inductively coupled plasma; chemometrics; optimization; multivariate data analysis; design of experiments; response surface model; siderophore; azathioprine; peptide; Analytisk kemi;

   Abstract : Liquid chromatography (LC) coupled to mass spectrometry (MS) offers highly selective and sensitive analysis of a wide variety of compounds. However, the use of hyphenated experimental set-ups implies that many parameters may have an effect on the studied response. READ MORE

5. 3. Aerodynamic Design and Optimization of Intermediate Ducts for High By-pass Ratio Jet Engines

   Author : Fredrik Wallin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate transition ducts; vortex generators; S-shaped ducts; response surface methodology; source term model; optimization;

   Abstract : Demands on improved efficiency and reduced noise levels cause a strive toward high by-pass ratio commercial aero engines. This results in multi-spool aero engines with small high-pressure ratio cores and large fans. The low-pressure system has a lower rotational speed and a larger radius than the high-pressure core system. READ MORE

6. 4. Metamodel based multi-objective optimization

   Author : Kaveh Amouzgar; Peter Hansbo; Niclas Strömberg; Kent Salomonsson; Sunith Bandaru; Jönköping University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-objective optimization; strength Pareto evolutionary algorithm; SPEA2; metamodel; surrogate model; response surface; radial basis functions; RBF;

   Abstract : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. READ MORE

7. 5. Reliability Assessment and Probabilistic Optimization in Structural Design

   Author : Rami Mansour; Mårten Olsson; Xioping Du; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design optimization RBDO ; First- and Second-Order Reliability Method FORM and SORM ; Response Surface Single Loop RSSL ; Probability of failure; Reliability Assessment; Probability of fatigue failure; Hållfasthetslära; Solid Mechanics;

   Abstract : Research in the field of reliability based design is mainly focused on two sub-areas: The computation of the probability of failure and its integration in the reliability based design optimization (RBDO) loop. Four papers are presented in this work, representing a contribution to both sub-areas. READ MORE
