16. Managing Geometrical Variation through Optimization and Visualization
Abstract : All manufacturing processes are afflicted by variation that causes deviations in critical dimensions in the final product. Geometrical variation results in form and size deviation in individual parts. Assembly variation comes from defects in assembly equipment, and influence how parts are mounted together. READ MORE

17. Machinery diagnostic techniques for maintenance optimization
Abstract : One of the future challenges of machinery diagnostics and prognosticsis to prepare for the Internet of Things (IoT), where it is possible to change and improve existing approaches drastically. An intensifying application of the IoT will increase the use of embedded sensors and, therefore, create a demand for diagnostic tools where manual workis minimized and is mainly handled by smart algorithms.

20. Optimization of Maintenance Planning for Multi-Component Systems, and Primal-Dual Convergence Characterizations in Convex Optimization
Abstract : This thesis considers two topics within mathematical programming. The first topic is an investigation into the behaviour of primal-dual subgradient algorithms with primal ergodic averaging in the case where it is not known a priori whether the primal program is consistent or not.
