1. On Functional Tolerances in Machine Design
Sammanfattning : This thesis describes a method that allows tolerances on critical dimensions to be assigned with respect to both quality and manufacturing cost. To be able to quantify and include customer needs in the process of assigning tolerances, the concept of functionality loss is used. LÄS MER
2. Computer aided tolerance allocation in mechanical design
Sammanfattning : .... LÄS MER
3. Efficient Density Matrix Methods for Large Scale Electronic Structure Calculations
Sammanfattning : Efficient and accurate methods for computing the density matrix are necessary to be able to perform large scale electronic structure calculations. For sufficiently sparse matrices, the computational cost of recursive polynomial expansions to construct the density matrix scales linearly with increasing system size. LÄS MER
4. Towards improvement of geometrical quality for manual assembly parts
Sammanfattning : Geometrical variation affects all mass-produced products. This variation will lead to deviations from the nominal design of the product both in terms of aesthetical and functional properties. Geometrical variation originates either from the manufacturing of the parts or from the assembly process. LÄS MER
5. Effective development of haptic devices using a model-based and simulation-driven design approach
Sammanfattning : Virtual reality (VR)-based surgical simulators using haptic devices can increase the effectiveness of surgical training for surgeons when performing surgical procedures in hard tissues such as bones or teeth milling. The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device, which reflects the interaction with the virtual model. LÄS MER
