1. 11. Laminated Veneer Products : Shape Stability and Effect of Enhanced Formability on Bond-Line Strength

   Författare :Lars Blomqvist; Jimmy Johansson; Hans Petersson; Dick Sandberg; Peter Niemz; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : This thesis concerns two aspects of the manufacture of laminated veneer products (LVPs). The first aspect is related to the possible improvement of the shape stability of LVPs, and the second has its starting point in the modification of the veneer for enhanced formability as well as the question of whether and how these modifications affect the bond-line strength.

3. 12. Low Power and Low Complexity Shift-and-Add Based Computations

   Författare :Kenny Johansson; Oscar Gustafsson; Lars Wanhammar; Izzet Kale; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Function approximation; Digital circuits; Computer arithmetic; Constant multiplication; Addition; Low power; Switching activity estimation; Electronics; Elektronik;

   Sammanfattning : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplications, which are realized using shift-and-add based computations. The possibilities to reduce the complexity, i.e. LÄS MER

4. 13. Reconstruction of a stationary flow from boundary data

   Författare :Tomas Johansson; Lars-Erik Andersson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cauchy problem; Generalized Stokes system; Ill-posed problems;

   Sammanfattning : We study a Cauchy problem arising in uid mechanics, involving the socalled stationary generalized Stokes system, where one should recover the ow from boundary measurements. The problem is ill-posed in the sense that the solution does not depend continuously on data.Two iterative procedures for solving this problem are proposed and investigated. LÄS MER

5. 14. Low Power and Low complexity Constant Multiplication using Serial Arithmetic

   Författare :Kenny Johansson; Lars Wanhammar; Oscar Gustafsson; Süleyman Demirsoy; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Computer arithmetic; Multiplication; Addition; Low power; Switching activity; Electronics; Elektronik;

   Sammanfattning : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplication using serial arithmetic. The possibility to reduce the complexity and energy consumption is investigated. LÄS MER

7. 15. Organizational death and employee motivation : Investigating a plant closure in a multi-plant organization

   Författare :Lars Häsänen; Johnny Hellgren; Gunn Johansson; Lena Mårtensson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Plant closure; closedown; goal theory; goal setting; motivation; organizational death; productivity; efficiency; performance and psychological climate; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : Major organizational changes are often connected with a variety of negative outcomes for both employees and the organization alike. As a contrast to this, organizational deaths have instead been associated with increased productivity and motivation to perform, despite certainty of job loss. LÄS MER
