  2. 1. Fast Algorithms for Integral Equations and Least Squares Identification Problems

    Author : Stefan Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

    Abstract : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels.

  4. 2. Cardiac surgery and the kidney - studies on the effects of pharmacological interventions on renal perfusion, filtration and oxygenation

    Author : Gudrun Bragadottir; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute; glomerular filtration rate; renal circulation; oxygen consumption; cardiac surgery; vasopressin; mannitol; levosimendan; estimating equations;

    Abstract : Acute kidney injury (AKI) commonly complicates cardiac surgery and is associated with high mortality. Renal ischemia is considered to be the major cause. There is a close association between glomerular filtration rate (GFR), tubular sodium reabsorption and renal oxygen consumption (RVO2) in humans. READ MORE

  5. 3. Some aspects of statistical inference in systems of equations

    Author : Ghazi Shukur; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; small sample properties.; misspecification; system of equations; dynamic specification; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : The objective of this thesis is to develop a strategy for statistical/econometric inferences applicable to systemwise testing of econometric models. A common deficiency in many applied econometric studies is the absence of statistical diagnostic testing. READ MORE

  6. 4. Identification and Estimation for Models Described by Differential-Algebraic Equations

    Author : Markus Gerdin; Torkel Glad; Lennart Ljung; Manfred Deistler; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-Algebraic Equations; Identifiability; Nonlinear systems; Modelling; Identification; Descriptor systems; Automatic control; Reglerteknik;

    Abstract : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. READ MORE

  7. 5. Estimating Effective Interactions from Particle Trajectories

    Author : Kolbjörn Tunström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

    Abstract : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. READ MORE
