1. Flexible Circuits and Materials for Creating Large-Area RFID Reader Antenna Systems
Sammanfattning : One of the applications for RFID technology is to monitor and position RFID-tagged objects over large volumes. To achieve this, one possible option is to implement RFID reader antennas, which are relatively thin but with significantly large areas, and place them beneath the RFID-tagged objects. LÄS MER
2. Approximate Methods of Optimal Control via Dynamic Programming Models
Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data and perform online simulation, this thesis studies the discrete-time infinite horizon optimal control problems and introduces some approximate solution methods via abstract dynamic programming (DP) models.

3. Approximate Solution Methods to Optimal Control Problems via Dynamic Programming Models
Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data, this thesis introduces some suboptimal schemes via abstract dynamic programming models.

4. Who benefits when IKEA enters local markets in Sweden? : An empirical assessment using difference-in-difference analysis, synthetic control methods, and Twitter sentiment analysis
Sammanfattning : Policy makers often spend considerable amounts of money to attract IKEA to their region despite not having any empirical measurements on its expected contribution to the local economy. As such, an empirical study of the economic and social impact of new IKEA stores can aid political decision making, and contribute to the literature regarding how big-box retail entry affects the regions where they enter.

5. High frequency electronic packaging and components : characterization, simulation, materials and processing
Sammanfattning : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both high density interconnects and high frequency devices have led to the search for new materials, material combinations, methods, processes and production equipment.
