1. 1. Scattering of elastic waves by an anisotropic sphere

   Författare :Ata Jafarzadeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sphere; T matrix; Effective wave number; Distribution of inclusions; Phase velocity.; Anisotropy; Attenuation; Scattering;

   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

3. 2. Towards Musicking in a Public Sphere : 1-3 year olds and music pedagogues negotiating a music didactic identity in a Swedish preschool

   Författare :Maria Wassrin; Eva Österlind; Ketil Thorgersen; Tiri Bergesen Schei; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Music education; musicking; early childhood education; preschool; age power structures; very young children; subject specific didactics; public sphere; Hannah Arendt; cultural studies; Subject Learning and Teaching; ämnesdidaktik;

   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

4. 3. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation

   Författare :Joakim Jaldén; Björn Ottersten; Zhi-Quan Luo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; MIMO; Detection; Sphere Decoder; Semidefinite Relaxation; Telecommunication; Telekommunikation;

   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.

5. 4. Women in the public sphere in Egypt : 2011–2014

   Författare :Imad Rasan; Sociologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; women; public sphere; visibility; collectivity; marginalisation; gender; sexual harassment; graffiti;

   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

7. 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

   Författare :Cornelis Dekker; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   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
