1. 21. Improvements for IceCube Event Reconstruction through Geometry Calibration and Photon Timing Distributions

   Författare :Matti Jansson; Klas Hultqvist; Chad Findley; Aart Heijboer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Large detector systems for particle and astroparticle physics; Neutrino detectors; Splines; Maximum likelihood; Physics; fysik;

   Sammanfattning : The origin of high-energy cosmic rays is an unsolved mystery because cosmic rays do not travel in a straight line but are bent by magnetic fields due to their electric charge. High energy neutrinos are predicted to be created close to these origins, and are an unambiguous probe, while gamma rays could be obscured or created by other processes. LÄS MER

3. 22. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation

   Författare :Thomas Metz; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pulsed lasers; Physics; Fysik; Laser technology; Laserteknik; non-linear spectroscopy; maximum likelihood; curve fitting; data adjustment; statistical inference; formaldehyde; PAH; polycyclic aromatic hydrocarbons; lifetime imaging; two-dimensional; streak camera; LIF; laser-induced fluorescence; Fluorescence lifetimes; time-resolved;

   Sammanfattning : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. LÄS MER

4. 23. On Parameter Estimation Employing Sinewave Fit andPhase Noise Compensation in OFDM Systems

   Författare :Senay Negusse; Peter Händel Professor; Per PhD Zetterberg Docent; Mikko Valkama; KTH; []

   Sammanfattning : In today’s modern society, we are surrounded by a multitude of digital devices.The number of available digital devices is set to grow even more. As the trendcontinues, product life-cycle is a major issue in mass production of these devices. LÄS MER

5. 24. Spectral Analysis of Nonuniformly Sampled Data and Applications

   Författare :Prabhu Babu; Peter Stoica; Fredrik Gustafsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral analysis; array processing; nonuniform sampling; sparse parameter estimation; direction of arrival DOA estimation; covariance fitting; sinusoidal parameter estimation; maximum-likelihood; non-parametric approach; exoplanet detection; radial velocity technique; Sudoku; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : Signal acquisition, signal reconstruction and analysis of spectrum of the signal are the three most important steps in signal processing and they are found in almost all of the modern day hardware. In most of the signal processing hardware, the signal of interest is sampled at uniform intervals satisfying some conditions like Nyquist rate. LÄS MER
