1. 1. Real Time Drag Minimization

   Författare :Marianne Jacobsen; Ulf Ringertz; Anders Forsgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; optimization; experimental verification; Vehicle engineering; Farkostteknik;

   Sammanfattning : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. LÄS MER

3. 2. Physical restraint use and falls in institutional care of old people : effects of a restraint minimization program

   Författare :Tony Pellfolk; Karlsson Stig; Knut Engedal; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical restraints; falls; dementia; care of the elderly; risk factors; work environment; restraint minimization education program; staff knowledge and attitude; and quality of care.; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; Geriatrics; geriatrik;

   Sammanfattning : Physical restraint use and falls are common in institutional care of old people and various attempts have been made to reduce their occurrence. Falls and concomitant injuries are a major problem due to their negative effect on morbidity and mortality. LÄS MER

4. 3. Direct and Inverse Methods for Waveguides and Scattering Problems in the Time Domain

   Författare :Erik Abenius; Per Lötstedt; Mats Gustafsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; time-domain; FDTD; finite-element; hybrid; thin sheet; waveguide; PML; inverse scattering; adjoint; gradient-based; minimization; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Sammanfattning : Numerical simulation is an important tool in understanding the electromagnetic field and how it interacts with the environment. Different topics for time-domain finite-difference (FDTD) and finite-element (FETD) methods for Maxwell's equations are treated in this thesis. LÄS MER

5. 4. Algorithms in data mining using matrix and tensor methods

   Författare :Berkant Savas; Lars Eldén; Lieven De Lathauwer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volume; Minimization criterion; Determinant; Rank deficient matrix; Reduced rank regression; System identification; Rank reduction; Volume minimization; General algorithm; Handwritten digit classification; Tensors; Higher order singular value decomposition; Tensor approximation; Least squares; Tucker model; Multilinear algebra; Notation; Contraction; Tensor matricization; Newton s method; Grassmann manifolds; Product manifolds; Quasi-Newton algorithms; BFGS and L-BFGS; Symmetric tensor approximation; Local intrinsic coordinates; Global embedded coordinates; ; Numerical analysis; Numerisk analys;

   Sammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER

7. 5. Reduction Techniques for Finite (Tree) Automata

   Författare :Lisa Kaati; Parosh Aziz Abdulla; Frank Drewes; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite automata; tree automata; bisimulation; minimization; simulation; composed bisimulation; composed simulation; Datavetenskap; Computer Science;

   Sammanfattning : Finite automata appear in almost every branch of computer science, for example in model checking, in natural language processing and in database theory. In many applications where finite automata occur, it is highly desirable to deal with automata that are as small as possible, in order to save memory as well as excecution time. LÄS MER
