1. 1. Model Based Coding : Initialization, Parameter Extraction and Evaluation

   Författare :Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Model-based coding; Motion estimation; Vision based tracking; Initialization; Analysis-by-Synthesis; Texture mapping; Active tracking.; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

   Sammanfattning : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. LÄS MER

3. 2. Model-based coding : extraction, coding, and evaluation of face model parameters

   Författare :Jörgen Ahlberg; Andrew Senior; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis deals with model-based coding of human faces for low bitrate communication. The basicidea of model-based coding is that the appearance and motion of a human face are analysed. By thisanalysis, compact parameters allowing realistic visualization of a synthetic face are extracted. LÄS MER

4. 3. Logistics-based Competition : A Business Model Approach

   Författare :Tobias Kihlén; Mats Abrahamsson; Daniel Kindström; Andreas Norrman; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; logistics-based competition; business model; logistics strategy; strategy; logistics; Business and economics; Ekonomi;

   Sammanfattning : Logistics is increasingly becoming recognised as a source of competitive advantage, both in practice and in academia. The possible strategic impact of logistics makes it important to gain deeper insight into the role of logistics in the strategy of the firm. LÄS MER

5. 4. Dose Adaptation Based on Pharmacometric Models

   Författare :Johan Wallin; Mats Karlsson; Lena Friberg; Maria Garrido; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : Many drugs exhibit major variability in both pharmacokinetic (PK) and pharmacodynamic (PD) parameters that prevents the use of the same dose for all patients. Variability can occur both between patients (IIV) as well as within patients over the course of time (IOV). LÄS MER

7. 5. Modelling animal populations

   Författare :Åke Brännström; Umeå universitet; []
   Nyckelord :population model; stochastic population model; population dynamics; discrete time model; Beverton-Holt model; Skellam model; Hassell model; Ricker model; first principles; coupled map lattice; CML; area integral; square function; Mathematics; matematik;

   Sammanfattning : This thesis consists of four papers, three papers about modelling animal populations and one paper about an area integral estimate for solutions of partial differential equations on non-smooth domains. The papers are: I. Å. Brännström, Single species population models from first principles. LÄS MER
