  2. 1. Identification and Control of Systems Subject to Abrupt Changes

    Author : Mille Millnert; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive identification; adaptive control; jumping parameters; Markov regime; time varying parameters;

    Abstract : Many different recursive identification methods for time varying systems have been suggested in the literature. An assumption that the variations in the system parameters are slow is common for almost all the methods. READ MORE

  4. 2. Adaptive Forgetting through Multiple Models and Adaptive Control of Car Dynamics

    Author : Peter Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive forgetting; Multiple models; Adaptive control; Car dynamics;

    Abstract : A new recursive identif ication method, Adaptive Forgetting through Multiple Models - AFMM, is presented and evaluated using computer simulations. AFMM is specif ically suited for identification of systems with jumping or rapidly changing parameters. READ MORE

  5. 3. On Hypersurface Coamoebas and Integral Representations of A-Hypergeometric Functions

    Author : Jens Forsgård; Boris Shapiro; Elizabeth Wulcan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; matematik; Mathematics;

    Abstract : This thesis is concerned with coamoebas and their connection to integral representations A-hypergeometric functions. In the first part, we introduce the lopsidedness criterion for coamoebas, and define the lopsided coamoeba. We show that the lopsided coamoeba comes naturally equipped with an order map. READ MORE

  6. 4. Water-Induced Charge Transport in Microcrystalline Cellulose

    Author : Martin Nilsson; Maria Strømme; Göran Alderborn; Jürgen Einfeldt; Uppsala universitet; []
    Keywords : Materials science; Materialvetenskap;

    Abstract : Microcrystalline cellulose (MCC) is the most frequently used excipient for direct compaction of tablets within the pharmaceutical industry. It has earlier been indicated that the interactions between the hydration shell – surrounding the drug molecules in an MCC tablet – and the cellulose regulate the speed of the drug release process.

  7. 5. On friction in metal power compaction process

    Author : Naghi Solimannezhad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The present work describes different ways of measuring and studying friction in a metal powder compaction process. Reducing friction during this process will allow an increase in the density of powder components and reduce variation in the density, which is a common problem in this process. This work contain three papers. READ MORE
