1. 1. Viscoelastic Materials : Identification and Experiment Design

   Författare :Agnes Rensfelt; Torsten Söderström; Händel Peter; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscoelastic materials; complex modulus; system identification; optimal experiment design; distributed parameter systems; frequency domain identification; wave propagation; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. LÄS MER

3. 2. Topics in optimal design of experiments

   Författare :Sofia Normark; Hans Nyquist; Johan Lyhagen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal design; factorial experiments; minimax designs; efficiency; locally optimal designs; generalized linear models; binary data; statistik; Statistics;

   Sammanfattning : This thesis contributes to optimal design of experiments in situations where the optimal design depends on unknown parameters. Such situations often occur when the response variable does not have normal distribution, as is the case with many generalized linear models (GLM) and many models for binary response. LÄS MER

4. 3. Optimal design for dose-finding studies

   Författare :Renata Eirini Tsirpitzi; Frank Miller; Kirsten Schorning; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bivariate model; distortion; drug combination; Elfving set; Emax model; Fedorov algorithm; mixed effects models; optimal experimental design; Statistics; statistik;

   Sammanfattning : One of the most complex tasks during the clinical development of a new drug is to find a correct dose. Optimal experimental design has as a goal to find the best ways to perform an experiment considering the available resources and the statistical model. Optimal designs have already been used to determine the design of dose-finding studies. LÄS MER

5. 4. Multidisciplinary Design of Transonic Fans for Civil Aeroengines

   Författare :Oliver Sjögren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design of experiment; Turbofan performance; Stochastic sensitivity analysis; Jet propulsion; Performance optimization; Multidisciplinary design; Transonic fan stage design;

   Sammanfattning : For current state-of-the-art turbofan engines the bypass section of the fan stage alone provides the majority of the total thrust in cruise and the size of the fan has a considerable effect on overall engine weight and nacelle drag. Thrust requirements in different parts of the flight envelope must also be satisfied together with sufficient margins towards stall. LÄS MER

7. 5. Optimal input design for nonlinear dynamical systems : a graph-theory approach

   Författare :Patricio E. Valenzuela Pacheco; Cristian R. Rojas; Roland Hildebrand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input design; Markov chains; system identification; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Optimal input design concerns the design of an input sequence to maximize the information retrieved from an experiment. The design of the input sequence is performed by optimizing a cost function related to the intended model application. Several approaches to input design have been proposed, with results mainly on linear models. LÄS MER
