2. 6. Dynamic Matrix Algorithms and Applications in Convex and Combinatorial Optimization

   Author : Jan van den Brand; Danupon Na Nongkai; Santosh Vempala; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dynamic Algorithm; Data Structure; Optimization; Linear Program; Bipartite Matching; Shortest Path; Maximum Flow; Minimum Cost Flow; Diameter; Computer Science; Datalogi;

   Abstract : Dynamic algorithms are used to efficiently maintain solutions to problems where the input undergoes some changes.This thesis studies dynamic algorithms that maintain solutions to linear algebra problems and we explore their applications and implications for dynamic graphs and optimization problems.

4. 7. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

   Author : Fatima Hlal; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

   Abstract : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. READ MORE

5. 8. Topology Optimization of Fatigue-Constrained Structures

   Author : Henrik Svärd; Krister Svanberg; Pierre Duysinx; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; topology optimization; fatigue constraints; stress constraints; density filters; restriction methods; weakest link theory; critical plane criteria; Mathematics; Matematik;

   Abstract : Fatigue, or failure of material due to repeated cyclic loading, is one of the most common causes of mechanical failures. The risk of fatigue in a load carrying component is often lowered by adding material, thereby reducing stresses. READ MORE

6. 9. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

   Author : Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. READ MORE

7. 10. Framework for cost and weight efficient conceptual design of automotive composite body structures

   Author : Per Mårtensson; Dan Zenkert; Kevin Potter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composites automotive cost weight body structure; Flyg- och rymdteknik; Aerospace Engineering; Fiber- och polymervetenskap; Fibre and Polymer Science; Transportvetenskap; Transport Science;

   Abstract : The automotive industry is facing a great challenge - reducing the weight of their vehicles. Carbon fibre composites are regarded by many as the only real option as traditional engineering materials are now running out of potential for further weight reduction. READ MORE
