2. 1. Vibrational Response Reconstruction and Model Validation

   Author : Anders Johansson; [2008]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error metrics; response reconstruction; controllability; rig test; drive signal identification; inverse problems; model validation; state space; model updating;

   Abstract : In this thesis, laboratory response reconstruction andcomputational model validation is investigated. The former concernsapplications of control theory as the objective is to reproduce acertain loading for a known component, while the latter concernsoptimization of a parameterized model as the objective is to modifya computational model to mimic a certain component's behavior.

4. 2. Communication in the context of acute pain : Persuasion or validation?

   University dissertation from Örebro : Örebro University

   Author : Johan Carstens Söderstrand; Örebro universitet.; [2018]
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Acute pain; communication; validation; reassurance; expectations for recovery; catastrophizing; recall; misdirected problem solving; psycho-logical flexibility;

   Abstract : Historically, the dominating theoretical framework for communication in the context of acute pain is reassurance. An inherent assumption of this framework is that the person in pain needs to have their fears and doubts removed and be educated, or persuaded, that the pain problem is not dan-gerous. READ MORE

5. 3. Covariate Model Building in Nonlinear Mixed Effects Models

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Jakob Ribbing; Uppsala universitet.; [2007]
   Keywords : Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Modeling; Covariate selection; Stepwise selection; Covariate analysis; Methodology; Model validation; Model evaluation; Type-2 diabetes; Beta-cell function; Meta analysis; Cross-validation; Least absolute shrinkage and selection operator; Pharmacometrics; ED optimization; Farmakokinetik Farmakoterapi;

   Abstract : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. READ MORE

6. 4. Drug Analysis Bioanalytical Method Development and Validation

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Mikaela Malm; Uppsala universitet.; [2008]
   Keywords : Analytical chemistry; African trypanosomiasis; calibration model; chiral chromatography; dried blood spots; eflornithine; evaporative light-scattering detection; HIV AIDS; lamivudine; liquid chromatography; malaria; nevirapine; piperaquine; pneumonia; solid-phase extraction; sulfadoxine; sulfamethoxazole; validation; zidovudine; Analytisk kemi;

   Abstract : This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries.Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography.

7. 5. Optimization and Model Validation of Transonic Compressors

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Lars R Ellbrant; [2012]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressor; optimization; design; metamodels; CFD; validation; multiobjective;

   Abstract : Economical aspects such as reduced specific fuel consumptions and ever growing environmental requirements on emissions and percieved noise levels, are the major drivers in the search for improvement of aircraft engines. For turbofan engines, the global trend is towards higher efficiency which is accomplished by increasing component efficiencies, the bypass ratio and overall pressure ratio while keeping the engine weight low.
