1. 1. Business Basics : A Grounded Theory for Managing Ethical Behavior in Sales Organizations

   Författare :Benny Berggren Newton; Lars-Johan Åge; Aihie Osarenkhoe; Erik A. Borg; Jens Hultman; Södertörns högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Management; Ethical Behavior; Business Basics; Sales Organizations; Grounded Theory; Management; Etiskt beteende; Business Basics; Säljande organisationer; Grundad Teori; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering;

   Sammanfattning : Background: Managing co-workers’ ethical behavior in sales organizations is a complex social process. To start, sales organizations incorporate several actors to manage, often simultaneously, all with their own agendas. LÄS MER

3. 2. Multigrid Preconditioners for the Discontinuous Galerkin Spectral Element Method : Construction and Analysis

   Författare :Lea Miko Versbach; Numerisk analys; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Discontinuous Galerkin Method; Finite Volume Method; Implicit Schemes; Local Fourier Analysis; Multigrid Method; Preconditioner; Space-Time Discretization; Spectral Element Method;

   Sammanfattning : Discontinuous Galerkin (DG) methods offer a great potential for simulations of turbulent and wall bounded flows with complex geometries since these high-order schemes offer a great potential in handling eddies. Recently, space-time DG methods have become more popular. LÄS MER

4. 3. Efficient Solvers for Space-Time Discontinuous Galerkin Spectral Element Methods

   Författare :Lea Miko Versbach; Numerisk analys; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Discontinuous Galerkin Method; Spectral Element Method; Finite Volume Method; Implicit Schemes; Preconditioner; Multigrid Method; Space-Time; Lobatto IIIC Method; Local Fourier Analysis;

   Sammanfattning : In this thesis we study efficient solvers for space-time discontinuous Galerkin spectral element methods (DG-SEM). These discretizations result in fully implicit schemes of variable order in both spatial and temporal directions. LÄS MER

5. 4. A Newton Method for Solving Non-Linear Optimal Control Problems with General Constraints

   Författare :Henrik Jonson; Torkel Glad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Newton method; Non-linear; Control problems;

   Sammanfattning : Optimal control of general dynamic systems under realistic constraints on input signals and state variables is an important problem area in control theory. Many practical control problems can be formulated as optimization tasks, and this leads toa significant demand for efficient numerical solution algorithms. LÄS MER

7. 5. Adaptive Finite Element Methods for Optimal Control Problems

   Författare :Karin Kraft; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dual weighted residual; adaptive; Newton method; variational inequality; vehicle dynamics.; multilevel algorithm; discontinuous Galerkin method; a posteriori error estimate; finite element method; optimal control; control constraint;

   Sammanfattning : In this thesis we study the numerical solution of optimal control problems. The problems considered consist of a systemof differential equations, the state equations, which are governed bya control variable. The goal is to determine the states and controls which minimize a given cost functional. LÄS MER
