16. Planning Robotic Assembly Sequences
Sammanfattning : In the automotive industry, short ramp up times and high product quality drive the development toward state-of-the-art solutions both in the research and industrial perspective. In addition to that, a sustainable industry requires optimized equipment utilization, in terms of materials used and consumed energy. LÄS MER
17. Matematiskt gestaltande i förskolan
Sammanfattning : The purpose of the thesis is to study how mathematics is experienced and used in preschool children’s activities and how preschool teachers frame their teaching of mathematical content. The studies include analyses of children’s actions in different activities from a mathematical perspective and preschool teachers’ intentions with and their teaching of mathematics. LÄS MER
18. Geometric Variation Simulation for the Development of Products with Plastic Components
Sammanfattning : Every manufactured product deviates from the intended product. Furthermore, in a series of products geometrical variation is always present. This variation will lead to functional and aesthetical variation of the product. Geometrical variation stems from variation in the manufacturing of parts and fixtures and variation in assembly operations. LÄS MER
19. Design for Producibility in Fabricated Aerospace Components - A framework for predicting and controlling geometrical variation and weld quality defects during multidisciplinary design
Sammanfattning : In the aerospace industry, weight reduction has been one of the key factors in making aircraft more fuel efficient in order to satisfy environmental demands and increase competitiveness. One strategy adopted by aircraft component suppliers to reduce weight has been fabrication, in which small cast or forged parts are welded together into a final shape. LÄS MER
20. FEM Modelling of Micro-galvanic Corrosion in Al Alloys Induced by Intermetallic Particles : Exploration of Chemical and Geometrical Effects
Sammanfattning : Localized corrosion, such as pitting, crevice corrosion or galvanic corrosion, is a long-standing phenomenon that can greatly limit the life of metallic materials. For decades experimental methods have been used to try to understand the underlying physical, chemical and electrochemical processes that control localized corrosion in order to find effective protection methods against its propagation.
