6. The network performance assessment model : a new framework of regulating the electricity network companies
Abstract : When the Swedish electricity market was re-regulated in 1996 the trading with electricity was exposed to competition and the net service henceforth should be comprised by a monopoly comprised by a regulation. The regulation was based on a review of the costs of the network companies. No attention were paid to if the network was efficient. READ MORE

8. Demand responsive resource management for cellular networks : link asymmetry, pricing and multihopping
Abstract : Economic affordability of services and infrastructures has rapidly become one of the key issues in the evaluation and design of wireless access systems. The provisioning of high data rates, at an ``affordable'' price, constitutes a serious challenge to the structure and management of current and future wireless networks. READ MORE

9. Grey-box Identification of Distributed Parameter Systems
Abstract : This thesis considers the problem of making dynamic models for industrial processes by combining physical modelling with experimental data. The focus is on distributed parameter systems, that is, systems for which the model structure involves partial differential equations (PDE). Distributed parameter systems are important in many applications, e. READ MORE

10. Electromagnetic Interference in Distributed Outdoor Electrical Systems, with an Emphasis on Lightning Interaction with Electrified Railway Network
Abstract : This thesis deals with the electromagnetic compatibility (EMC) problems of distributed electrical networks, especially that caused by lightning to electrified railway. Lightning transients were found to damage important devices that control train movements, causing traffic stoppage and delays. READ MORE
