1. 21. Matching of geometrically and topologically changing meshes

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Kristoffer Jonsson; [2015]
   Keywords : mesh; meshes; matching; matchings; topology; geometry; manifold; compression; animation; animations; fluid; spherical harmonics; tensor; bijective; game; games; DICE;

   Abstract : The aim for this thesis is to develop a foundation for a compression system for animated mesh sequences, specifically under dynamic change of mesh geometry and topology. Compression of mesh sequences is of special interest in the game industry and this particular thesis is a part of an ongoing series of projects at EA DICE. READ MORE

3. 22. Signal Processing for mmWave MIMO Radar

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Óscar Faus García; [2015]
   Keywords : radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

   Abstract : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.

   Keywords : ANN; artificial neural network; SOINN; SOTPAR; SOTPAR2; prediction; spatio-temporal pattern detection; temporal activity diffusion; pattern recognition; unsupervised learning; vector quantization; ANN; artificiellt neuralt nätverk; artificiella neurala nätverk; SOINN; SOTPAR; SOTPAR2; förutsägelse; spatio-temporal mönsterdetekion; temporal aktivitetsdiffusion; mönsterigenkänning; oövervakad inlärning; vektorkvantisering;

   Abstract : Vector Quantization (VQ) is a classic optimization problem and a simple approach to pattern recognition. Applications include lossy data compression, clustering and speech and speaker recognition. READ MORE

5. 24. Subband Adaptive Filtering Technique employing APA For Stereo Echo Cancellation over Audio Signals

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : BHANUDURGA SRI SATYA SIMHA EDAMAKANTI; VISHNU CHAITANYA GUNDU; [2014]
   Keywords : Stereo Echo Cancellation; NLMS; RLS; MCHA; APA; Subband Adaptive Modeling.; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

   Abstract : The world today is relying on hands free devices and teleconferencing equipments but the major problem with the use of these systems is creation of acoustic echo at the time of conversation. The quality of information to be transmitted and received is degraded due to the echo. READ MORE

6. 25. Data Compression in a Vehicular Environment

   University essay from KTH/Signalbehandling

   Author : Johan Lovén; [2014]
   Keywords : GPS; Accelerometer; Telematics; Vehicle;

   Abstract : Vehicles with sensors produce large amounts of data. Transmission of data is connectedwith costs. By using data compression, less data has to be transmitted, reducing priceof operation. A number of algorithms are evaluated through tests with GPS and accelerometerdata. READ MORE
