1. 16. Noise improves cognitive performance in children with dysfunctional neurotransmission

   Författare :Göran Söderlund; Sverker Sikström; Lars-Göran Nilsson; Edmund Sonuga-Barke; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; noise; stochastic resonance; dopamine; episodic memory; model; brain arousal; SPT; cognitive performance; children; Psychology; Psykologi; psykologi; Psychology;

   Sammanfattning : Research on children with Attention Deficit Hyperactivity Disorder (ADHD) has shown that they are extremely sensitive to distraction from external stimuli that lead to poor cognitive performance. This thesis shows that cognitive performance can be improved if this external stimulus is smooth and continuous (e.g. auditory white noise). LÄS MER

3. 17. Performance Analysis and Optimization via Simulation

   Författare :Anders Svensson; Institutionen för informatik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; performance analysis; load sharing; mathematical model formalism; real-time control; design; Telecommunication engineering; modular optimization; circuit switched networks; Telekommunikationsteknik;

   Sammanfattning : A large amount of scientific work has been carried out to enhance the methods used for design and control of technical systems. For many of these systems, the main objective is to utilize the limited resources in an optimal way. Different simulation techniques have, in many cases, been successfully applied to the analysis.

4. 18. Robust Multimedia Communications over Packet Networks

   Författare :Guoqiang Zhang; W. Bastiaan Kleijn; Vinay Vaishampayan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Sammanfattning : Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. LÄS MER

5. 19. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization

   Författare :Nils Fagerberg; Johan Bergh; Peter Lohmander; Stergios Adamopoulos; Hubert Hasenauer; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; continuous cover forestry; selective cutting; Picea abies; uneven-aged; single-tree-selection; growth model; knot size model; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER

7. 20. Complexity and Error Analysis of Numerical Methods for Wireless Channels, SDE, Random Variables and Quantum Mechanics

   Författare :Håkon Hoel; Anders Szepessy; Helse Holden; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Wireless Channels; SDE; Monte Carlo Methods; Molecular Dynamics; Quantum Mechanics;

   Sammanfattning : This thesis consists of the four papers which consider different aspects of stochastic process modeling, error analysis, and minimization of computational cost.     In Paper I, we construct a Multipath Fading Channel (MFC) model for wireless channels with noise introduced through scatterers flipping on and off.
