2. 1. Techniques for Efficient Implementation of FIR and Particle Filtering

   Author : Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

   Abstract : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters.

4. 2. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

   Author : Anders Engdahl; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

   Abstract : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. READ MORE

5. 3. Data driven modeling in the presence of time series structure: : Improved bounds and effective algorithms

   Author : Othmane Mazhar; Boualem Djehiche; Munther Dahleh; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time series; Non-asymptotic estimation; Minimax; Change point detection; Hidden Markov model; State space model; Least square; Penalized Regression; Random covariance matrix; Concentration inequality; Chaining integral; Self-normalized martingale inequality; Cramér-Rao inequality; van Trees inequality; Matematisk statistik; Mathematical Statistics;

   Abstract : This thesis consists of five appended papers devoted to modeling tasks where the desired models are learned from data sets with an underlying time series structure. We develop a statistical methodology for providing efficient estimators and analyzing their non-asymptotic behavior. READ MORE

6. 4. Low Power and Low complexity Constant Multiplication using Serial Arithmetic

   Author : Kenny Johansson; Lars Wanhammar; Oscar Gustafsson; Süleyman Demirsoy; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Computer arithmetic; Multiplication; Addition; Low power; Switching activity; Electronics; Elektronik;

   Abstract : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplication using serial arithmetic. The possibility to reduce the complexity and energy consumption is investigated. READ MORE

7. 5. Charge Sampling Circuits and A/D Converters - Theory and Experiments

   Author : Gang Xu; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

   Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE
