   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

3. 2. Mode switch for component-based multi-mode systems

   Författare :Hang Yin; Hans Hansson; Tomas Bures; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; component-based; multi-mode; mode switch; Computer Science; datavetenskap;

   Sammanfattning : Component-based software engineering is becoming a prominent solution to the development of complex embedded systems. Since it allows a system to be built by reusable and independently developed components, component-based development substantially facilitates the development of a complex embedded system and allows its complexity to be better managed.

4. 3. Introducing Mode Switch in Component-Based Software Development

   Författare :Hang Yin; Hans Hansson; Paul Pettersson; Thomas Nolte; Carlo Ghezzi; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mode switch; multi-mode; component-based; Computer Science; datavetenskap;

   Sammanfattning : Self-adaptivity, characterized by the ability to dynamically adjust behavior at runtime, is a growing trend in the evolution of modern embedded systems. While self-adaptive systems tend to be flexible and autonomous, self-adaptivity may inevitably complicate software design, test and analysis. LÄS MER

5. 4. Finite Element Methods for Thin Structures with Applications in Solid Mechanics

   Författare :Karl Larsson; Mats G Larson; Garth N Wells; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a priori error estimation; finite element method; discontinuous Galerkin; corotation; Kirchhoff-Love plate; curved beam; biharmonic equation; Mathematics; matematik;

   Sammanfattning : Thin and slender structures are widely occurring both in nature and in human creations. Clever geometries of thin structures can produce strong constructions while requiring a minimal amount of material. LÄS MER

7. 5. Magnetohydrodynamics of Turbulent Accretion Disks and Planet Formation

   Författare :Wladimir Lyra; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy and astrophysics; Astronomi och astrofysik;

   Sammanfattning : Planets have long been believed to form in disks of gas and dust around youngstars, interacting with their surroundings via a setof complex and highly nonlinear processes. In the core accretion scenario forgiant planet formation dust coagulates first into km-sized icyand rocky planetesimals that further collide, formingprogressively larger solid bodies that eventually give rise to cores of severalEarth masses.
