2. 11. Optimal Decisions with Limited Information

   Author : Ather Gattami; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems; numerical analysis; Computer science; Convex Optimization; Graph Theory; Team Decision Theory; Game Theory; control; Datalogi; numerisk analys; system; kontroll; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This thesis considers static and dynamic team decision problems in both stochastic and deterministic settings. The team problem is a cooperative game, where a number of players make up a team that tries to optimize a given cost induced by the uncertainty of nature. READ MORE

4. 12. Resource Allocation in Multi-Antenna Communication Systems with Limited Feedback

   Author : David Hammarwall; Björn Ottersten; David Gesbert; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : The use of multiple transmit antennas is considered a key ingredient to significantly improve the spectral efficiency of wireless communication systems beyond that of currently employed systems. Transmit beamforming schemes have been proposed to exploit the spatial characteristics of multi-antenna radio channels; that is, multiple-input single-output (MISO) channels. READ MORE

5. 13. Interference alignment and power control for wireless interference networks

   Author : Hamed Farhadi; Mikael Skoglund; Michail Matthaiou; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference alignment; power control; limited feedback; wireless communication; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : This thesis deals with the design of efficient transmission schemes forwireless interference networks, when certain channel state information(CSI) is available at the terminals.In wireless interference networks multiple source-destination pairsshare the same transmission medium for the communications.

6. 14. Computer-based speech therapy using visual feedback with focus on children with profound hearing impairments

   Author : Anne-Marie Öster; David House; James Mahshie; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech technology; hearing-imparment; speech therapy; visual feedback; second language learning; computer-based speech training; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : This thesis presents work in the area of computer-based speech therapy using different types of visual feedback to replace the auditory feedback channel. The study includes diagnostic assessment methods prior to therapy, type of therapy design, and type of visual feedback for different users during different stages of therapy for increasing the efficiency.

7. 15. Mathematical modelling approach to collective decision-making

   Author : Natalia Zabzina; Denis Gaidashev; Torbjörn Lundh; Uppsala universitet; []
   Keywords : collective behaviour; collective decision-making; communication mechanisms; positive feedback; mathematical modelling; bifurcation phenomena; steady state solutions; symmetry breaking; symmetry restoring; diffusion-limited aggregation; fractal dimension;

   Abstract : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. READ MORE
