4. 3. Identification of viscoelastic materials and continuous-time stochastic systems

   Författare :Magnus Mossberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; identification; viscoelastic; continuous-time; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

   Sammanfattning : Two system identification problems, identification of viscoelastic material properties and identification of continuous-time stochastic systems, are considered in the thesis. The viscoelastic material properties are characterised by the frequency-dependent complex modulus. LÄS MER

5. 4. Designing Space-Time Codes Using Orthogonal Designs

   Författare :Girish Ganesan; Thomas Marzetta; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space-time codes; Orthogonal designs; Amicable orthogonal designs; Differential detection; Trellis codes; Turbo codes; Signal processing; Signalbehandling; Signalbehandling; Signal Processing;

   Sammanfattning : This thesis deals with coding schemes for systems with multiple transmit antennas. The problem of finding optimal transmission schemes for the case when the transmitter knows the channel and the case when the transmitter does not know the channel are considered. LÄS MER

7. 5. Keeping track of time : Daily time management, participation, and time-related interventions for children, adolescents, and young adults with neurodevelopmental disorders

   Författare :Birgitta Wennberg; Per A Gustafsson; Anette Kjellberg; Gunnel Janeslätt; Maria Larsson-Lund; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; autonomy; ID; daily time management; intervention; occupational therapy; participation; time assistive devices; time processing ability;

   Sammanfattning : The overall aim of this thesis was to investigate daily time management (DTM) and time-related interventions aiming to enhance participation in everyday activities among school-age children and young adults with neurodevelopmental disorders.In study I, experiences of participation when using time assistive devices (TADs) in daily activities were investigated from the perspective of young adults (aged 17–37) with intellectual disabilities (ID) (n = 9), using semi structured interviews.
