1. Performing Punk : Subcultural Authentications and the Positioning of the Mainstream
Abstract : This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic.

2. Weighted Hardy-type inequalities on the cones of monotone and quasi-concave functions
Abstract : This PhD thesis deals with weighted Hardy-type inequalities restricted to cones of monotone functions and quasi-monotone functions.The thesis consists of four papers (papers A, B, C and D) and an introduction, which gives an overview of this specific field of functional analysis and also serves to put these papers into a more general frame.

3. Improvements of SPECT by a new collimator design and simultaneous transmission-emission tomography
Abstract : SPECT (Single Photon Emission Computed Tomography) and planar scintigraphy are the most established and world wide-spread nuclear medicine imaging techniques for clinical use today. SPECT is a tomographic technique that allows 3-D visualization of biochemical processes or physiological flow in the human body by external detection of photons from an administered radiopharmaceutical.

4. Millimeter-Wave Communications for Indoor Dense Spaces : Channel Modeling and Network Deployment
Abstract : In the ever-evolving landscape of wireless communication, the deployment of millimeter-wave (mmWave) technology has emerged as a game-changer for indoor environments. As the demand for high-speed, low-latency connectivity continues to surge, especially in densely populated areas, mmWave access point deployment has gained prominence due to its ability to deliver unprecedented data rates thanks to the available wide bandwidths.

5. The Maximum Principle for Cauchy-Riemann Functions and Hypocomplexity
Abstract : This licentiate thesis contains results on the maximum principle forCauchy–Riemann functions (CR functions) on weakly 1-concave CRmanifolds and hypocomplexity of locally integrable structures. Themaximum principle does not hold true in general for smooth CR functions,and basic counterexamples can be constructed in the presenceof strictly pseudoconvex points. READ MORE
