  1. 21. Robot path planning : an object-oriented approach

    Författare :Morten Strandberg; Bo Wahlberg; Steven La Valle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; mathematics; computer science; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : Path planning has important applications in many areas, for example industrial robotics, autonomous systems, virtual prototyping, and computer-aided drug design. This thesis presents a new framework for developing and evaluating path planning algorithms. The framework is named CoPP (Components for Path Planning). LÄS MER

  3. 22. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Författare :Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER

  4. 23. Multiple-Input Multiple-Output Radio Propagation Channels : Characteristics and Models

    Författare :Kai Yu; Björn Ottersten; David Gesbert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. LÄS MER

  5. 24. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Författare :Keren Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

  7. 25. Identification Techniques for Mathematical Modeling of the Human Smooth Pursuit System

    Författare :Daniel Jansson; Alexander Medvedev; Peter Stoica; Johan Schoukens; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear system identification; biomedical signal processing; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis proposes nonlinear system identification techniques for the mathematical modeling of the human smooth pursuit system (SPS) with application to motor symptom quantification in Parkinson's disease (PD). The SPS refers to the complex neuromuscular system in humans that governs the smooth pursuit eye movements (SPEM). LÄS MER
