1. Scattering of elastic waves by an anisotropic sphere
Sammanfattning : Scattering of a plane wave by a single spherical obstacle is the archetype of many scattering problems in physics and geophysics. Spherical objects can provide a good approximation for many real objects, and the analytic formulation for a single sphere can be used to investigate wave propagation in more complicated structures like particle composites or grainy materials, which may have application in non-destructive testing, material characterization, medical ultrasound, etc. LÄS MER
2. Towards Musicking in a Public Sphere : 1-3 year olds and music pedagogues negotiating a music didactic identity in a Swedish preschool
Sammanfattning : This thesis explores alternative ways of staging music in preschool. The ‘preschool subject of music’ is approached as a social and cultural construct that is embedded in discursive negotiations. Participants in the study are 1-3 year-old children and their music pedagogues, working in the preschool on a daily basis. LÄS MER
3. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation
Sammanfattning : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

4. Women in the public sphere in Egypt : 2011–2014
Sammanfattning : Through interviews, many documents and secondary data, this dissertation investigates how fifty-four women activists participated in the public sphere in Egypt from the outbreak of the 2011 uprising to the re-emergence of the authoritarian regime in 2014. The women activists studied in the dissertation took part in various counter-publics of social movements, opposition political parties, and civic engagement. LÄS MER
5. Judging in the public sphere : a philosophical and empirical inquiry inte ethico-political judgment and public discourse on prenatal diagnosis and screening in the Netherlands and Sweden
Sammanfattning : Judging is quintessential when dealing with a plurality of points of view in society concerning moral and political questions. In this inquiry, the concept of ethico-political judgment is elaborated as an ideal for public deliberation over moral and political questions. LÄS MER
