  1. 1. Improved pharmacometric model building techniques

    Författare :Radojka Savic; Mats Karlsson; Siv Jönsson; Matt Hutmacher; Uppsala universitet; []
    Nyckelord :Model building; Absorption model; Transit compartment model; Nonparametric method; Extended grid method; Semiparametric; Distribution transformation; Shrinkage; Model diagnostics;

    Sammanfattning : Pharmacometric modelling is an increasingly used method for analysing the outcome from clinical trials in drug development. The model building process is complex and involves testing, evaluating and diagnosing a range of plausible models aiming to make an adequate inference from the observed data and predictions for future studies and therapy.

  2. 2. Nonlinear Modeling of FETs for Microwave Switches and Amplifiers

    Författare :Ankur Prasad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HEMT; symmetry; small-signal model; field-plate.; GaAs; GaN; nonlinear model; trap model; symmetrical model; trap; model;

    Sammanfattning : The exponential growth in wireless systems require rapid prototyping of radio frequency circuits (RF) using computer-aided design (CAD) enabled models. Most of the RF circuits (e.g. switches, amplifiers, mixers, etc. LÄS MER

  3. 3. Stochastic model updating and model selection with application to structural dynamics

    Författare :Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

    Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

  4. 4. Architecting model driven system integration in production engineering

    Författare :Yujiang Li; Lars Mattsson; Gunilla Franzén Sivard; Torsten J. A. Kjellberg; Mikael Hedlind; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System architecture; system integration; information model; ISO 10303; application context; implementation context; implementation model.; Production Engineering; Industriell produktion;

    Sammanfattning : System integration is a key enabler to maximize information value in an engineering context. The valuable information is normally represented by information models which play a decisive role in the implementation of system integration. LÄS MER

  5. 5. Cluster model of disordered systems : application to doped semiconductors and a simple model polymer

    Författare :Rolf G. Riklund; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis we study with an extended cluster model calculation the combined effect of disorder and electron-electron interaction on the electronic structure of doped semiconductors and a simple model polymer chain. First a one-band model using a Hartree calculation is compared to other authors result for the impurity band using less realistic Hamiltonians. LÄS MER
