11. Optimization modeling of frequency reserves and inertia in the transition to a climate-neutral electricity system
Sammanfattning : The ongoing transition towards electricity production systems that are dominated by wind and solar power challenge both the traditional strategy for meeting a varying electricity demand and the traditional way of controlling the AC frequency of the electricity grid. This work investigates how frequency reserves (FR) and inertia, as well as inter-hourly variation management interact in the transition to a climate-neutral electricity system. LÄS MER
12. Geographic Accessibility Analysis - Methods and Application
Sammanfattning : Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. LÄS MER
13. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach
Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

14. Tumour stromal and demographical factors affecting the metastatic aggressiveness of small differentiated papillary thyroid cancers in Sweden
Sammanfattning : Background: The incidence of papillary thyroid cancer (PTC) has been increasing over the recent decades, especially that of small papillary thyroid cancers (sPTCs) (≤ 20mm in size). sPTCs are generally classified as low risk cancers with a very favourable diagnosis, yet some of these cancers still cause locoregional and distant metastasis, recurrence and even death.

15. An Operations Research Approach for Daily Emergency Management
Sammanfattning : Emergency services play a vital role in society by providing help to affected people and minimizing damage to public and private assets as well as the environment during emergencies. However, these organizations deal with problems of increasing demand uncertainty and resource shortage over time. LÄS MER
