1. Practical Deployment Aspects of Cell-Free Massive MIMO Networks
Sammanfattning : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. LÄS MER
2. Security of Electricity Supply in Power Systems : Establishing a Global Framework for Assessing Power System Health and Analyzing Outage Statistics in Sweden
Sammanfattning : The primary objective of this thesis is to enhance the security of electricity supply by providing a holistic perspective and introducing a comprehensive framework for assessing power system health. This novel approach aims for a thorough evaluation of the system’s overall performance and well-being, using the physical dimensions of the security of supply as the foundation for a power system health index.

3. Using Outage Probability to Tailor Communication Protocols Suitable for Cyber-Physical Systems Operating in Confined Areas
Sammanfattning : Some types of Cyber-Physical System (CPS) applications found within e.g., quarrying, mining, harbors, and construction sites, operate within confined areas. LÄS MER
4. On the Performance of Underlay Cognitive Radio Networks with Interference Constraints and Relaying
Sammanfattning : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. LÄS MER
5. Studies of safety and critical work situations in nuclear power plants : a human factors perspective
Sammanfattning : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. LÄS MER
