1. Radio Resource Allocation and Utilization in Multiple Radio Access Networks
Sammanfattning : Meeting in a sustainable way the demands of an unprecedented explosive growth in the number of connected devices and mobile data traffic, next-generation mobile networks are expected to make flexible use of spectrum and provide higher capacity by a denser deployment of radio access network infrastructure. In addition, the allocation and the utilisation of radio access resources should improve spectrum usage efficiency and keep energy consumption low, implying the capability to effectively exploit the denser deployment of radio accesses and the co-existence of radio accesses belonging to one or multiple radio access technologies.

2. Development and Application of Reactor Noise Diagnostics
Sammanfattning : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

4. Assessment of everyday functioning for adults with hearing loss : Development of Hearing and Functioning in Everyday life Questionnaire (HFEQ)
Sammanfattning : Aim: The overall aim of the current thesis was to develop a self-assessmentinstrument with a focus on everyday functioning for adults with hearingloss and to investigate its psychometric properties.Methods: Three different methods were applied in the current studies; a scoping review (Study I), two quantitative studies using two different datacollection processes (Study II and IV) and a qualitative study, including anitem-generation workshop and cognitive group interviews (Study III).

5. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children
Sammanfattning : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.
