1. 1. Low-Complexity Signal Processing for Speech Enhancement and Audio Analysis

   Författare :Markus Lindroth; Benny Lövström; Ingvar Claesson; Fredric Lindström; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied Signal Processing; Tillämpad signalbehandling;

   Sammanfattning : In real-time signal processing there is a constraint to finish processing of an audio signal before the next audio segment is received. This makes it important to have signal processing algorithms with low computational complexity while still maintaining high quality results. LÄS MER

3. 2. The relationship between orthology, protein domain architecture and protein function

   Författare :Kristoffer Forslund; Erik Sonnhammer; Cristina Al-Khalili Szigyarto; Sarah Teichmann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homology; orthology; paralogy; gene duplications; protein function prediction; low-complexity regions; protein domains; domain architecture evolution; introns; intron position conservation; orthology conjecture; domain grammar hypothesis; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

   Sammanfattning : Lacking experimental data, protein function is often predicted from evolutionary and protein structure theory. Under the 'domain grammar' hypothesis the function of a protein follows from the domains it encodes. LÄS MER

4. 3. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs

   Författare :Thomas Olsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; dual supply voltage; clock generator; digital; VHDL; CMOS; low-power; Distributed clocking; PLL;

   Sammanfattning : With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. LÄS MER

5. 4. Fundamental Limits in Wireless Wideband Networking

   Författare :Tan Tai Do; Mikael Skoglund; Tobias Oechtering; Olav Tirkkonen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The rapid growth of the wireless communication industry recently does not only bring opportunities but also challenges on developing radio technologies and solutions that can support high data rate as well as reliable and efficient communications. Two fundamental factors that limit the transmission rate are the available transmit energy and the available bandwidth. LÄS MER

7. 5. Nonlinear Model Predictive Control for Autonomous Vehicles

   Författare :Paolo Falcone; Universita degli Studi del Sannio; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this thesis we consider the problem of designing and implementing Model Predictive Controllers (MPC) for stabilizing the dynamics of an autonomous ground vehicle. For such a class of systems, the non-linear dynamics and the fast sampling time limit the real-time implementation of MPC algorithms to local and linear operating regions. LÄS MER
