1. On Multi-Disciplinary Optimization in Engineer-to-Order Product Configuration
Sammanfattning : Customized products are becoming increasingly common, and increasingly important for maintaining a competitive advantage in certain industries. Being able to quickly and accurately respond to unique customer requirements can provide a competitive edge or even be the only path to survival. LÄS MER
2. Efficient Optimization of Complex Products : A Simulation and Surrogate Model Based Approach
Sammanfattning : This thesis investigates how to use optimization efficiently when complex products are developed. Modelling and simulation are necessary to enable optimization of products, but here it is assumed that verified and validated models of the products and their subsystems are available for the optimization.

3. Market, State, and Morality : Two Studies of How Left and Right Undermined Moral Motivation in the Swedish School System
Sammanfattning : The bulk of the literature on the New Public Management (NPM) has been blind to the moral dimension of the market-oriented reforms of the public sector. However, this thesis studies the potential for institutional arrangements such as financial incentives and other market mechanisms to undermine intrinsic, moral motivation among both“producers” and “consumers” of tax-financed welfare services.

4. Interpreting Policy Convergence Between the Left and the Right
Sammanfattning : This dissertation is made up of four essays that address major problems in the policy areas of education and immigration in Sweden and an introductory essay that offers an overarching analysis of the results of the four individual studies. The first three essays analyze the significant decline in quality of elementary and secondary education since the late 1990s from three different angles: the decline in teachers’ working conditions and status (Essay I), the deficiencies in the regulatory framework of Sweden’s system of school competition between public and for-profit providers of education (Essay II), and the prescribed view of knowledge in Swedish schools (Essay III).

5. ASIP for Wireless Communication and Media
Sammanfattning : While general purpose processors reach both high performance and high application flexibility, this comes at a high cost in terms of silicon area and power consumption. In systems where high application flexibility is not required, it is possible to trade off flexibility for lower cost by tailoring the processor to the application to create an Application Specific Instruction set Processor (ASIP) with high performance yet low silicon cost.
