1. 16. Pontryagin approximations for optimal design

   Författare :Jesper Carlsson; Anders Szepessy; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topology Optimization; Inverse Problems; Hamilton-Jacobi; Regularization; Error Estimates; Impedance Tomography; Numerical analysis; Numerisk analys;

   Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for applications in optimal design and reconstruction. Such optimal control problems are often ill-posed and need to be regularized to obtain good approximations. LÄS MER

3. 17. Theology beyond Representation : Foucault, Deleuze and the Phantasms of Theological Thinking

   Författare :Petra Carlsson; Mattias Martinson; Anders Johansson; Philip Goodchild; Uppsala universitet; []
   Nyckelord :Theology; Representation; Representation critique; Michel Foucault; Gilles Deleuze; Thomas J.J. Altizer; Graham Ward; Emilia Fogelklou; Death of God theology; Radical Orthodoxy; Systematic Theology and Studies in Worldviews; Systematisk teologi med livsåskådningsforskning;

   Sammanfattning : Theology beyond Representation explores the theological opportunities embedded in Michel Foucault’s and Gilles Deleuze’s critique of Christian thinking and of what they regard as a Christian and oppressive logic of representation. Foucault’s and Deleuze’s thoughts on representation are currently discussed in many fields neighbouring theology (e. LÄS MER

4. 18. Utilizing Problem Structure in Optimization of Radiation Therapy

   Författare :Fredrik Carlsson; Anders Forsgren; Edwin Romeijn; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated radiation therapy; conjugate-gradient method; step-and-shoot delivery; column generation; quasi-Newton method; regularization; sequential quadratic programming; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : In this thesis, optimization approaches for intensity-modulated radiation therapy are developed and evaluated with focus on numerical efficiency and treatment delivery aspects. The first two papers deal with strategies for solving fluence map optimization problems efficiently while avoiding solutions with jagged fluence profiles. LÄS MER

5. 19. Optimal Control of Partial Differential Equations in Optimal Design

   Författare :Jesper Carlsson; Anders Szepessy; Peter Hansbo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimal design; Numerical analysis; Numerisk analys;

   Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for inverse problems in optimal design. Important examples of such problems are optimal material design and parameter reconstruction. In optimal material design the goal is to construct a material that meets some optimality criterion, e.g. LÄS MER

7. 20. Ideals and boundaries in Algebras of Holomorphic functions

   Författare :Linus Carlsson; Anders Fällström; Jan Wiegerinck; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; maximal ideal space; the Gleason problem; generalized Shilov boundaries; Nebenhülle; the Koszul complex; Banach algebras of holomorphic functions; MATHEMATICS; MATEMATIK;

   Sammanfattning : We investigate the spectrum of certain Banach algebras. Properties like generators of maximal ideals and generalized Shilov boundaries are studied. LÄS MER
