5. 3. Computational Complexity of some Optimization Problems in Planning

   Author : Meysam Aghighi; Peter Jonsson; Christer Bäckström; Hector Geffner; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Automated planning is known to be computationally hard in the general case. Propositional planning is PSPACE-complete and first-order planning is undecidable. One method for analyzing the computational complexity of planning is to study restricted subsets of planning instances, with the aim of differentiating instances with varying complexity. READ MORE

6. 4. Strong Partial Clones and the Complexity of Constraint Satisfaction Problems : Limitations and Applications

   Author : Victor Lagerkvist; Peter Jonsson; Christer Bäckström; Nadia Creignou; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this thesis we study the worst-case time complexity of the constraint satisfaction problem parameterized by a constraint language (CSP(S)), which is the problem of determining whether a conjunctive formula over S has a model. To study the complexity of CSP(S) we borrow methods from universal algebra. READ MORE

7. 5. Residual stresses, fatigue and deformation in cast iron

   Author : Mattias Lundberg; Johan Moverare; Ru Lin Peng; Taina Ahmad; Daniel Bäckström; Maqsood Ahmad; Sten Johansson; Mattias Calmunger; Peter Hedström; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The complex geometry of cylinder heads in heavy-duty diesel engines makes grey iron or compact graphite iron a preferred material choice due to its price, castability, thermal conductivity and damping capacity. Today’s strict emission laws have increased the demands on engine performance and engine efficiency. READ MORE
