  2. 1. Event Prediction and Bootstrap in Time Series

    Author : Anders Svensson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; bootstrap control.; statistical bootstrap; catastrophe; level-crossings; ARMAX process; Optimal alarm system; time series; optimal event predictor; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. READ MORE

  4. 2. Signal Processing Techniques for Detection of Buried Landmines using Ground Penetrating Radar

    Author : Håkan Brunzell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

    Abstract : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. READ MORE

  5. 3. Detection and Depth Sounding of Small Targets with Airborne Laser Bathymetry

    Author : Michael Tulldahl; Rainer Reuter; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The subject of this thesis is an investigation of the potential for detecting small targets (size about 1 m3) with airborne scanning laser depth sounding. Examples of other optical techniques of interest for small target detection are: range gated imaging, polarized detection and passive multispectral imaging. READ MORE

  6. 4. Stealthy Sensor Attacks on Feedback Systems : Attack Analysis and Detector-based Defense Mechanisms

    Author : David Umsonst; Henrik Sandberg; Hideaki Ishii; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis, we investigate sensor attacks on feedback systems and how anomaly detectors can be used as a defense mechanism. We consider an attacker with access to all sensor measurements and full knowledge about the closed-loop system model. READ MORE

  7. 5. Sound Classification in Hearing Instruments

    Author : Peter Nordqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound Classification HMM Hearing Aid; Signal processing; Signalbehandling;

    Abstract : A variety of algorithms intended for the new generation of hearing aids is presented in this thesis. The main contribution of this work is the hidden Markov model (HMM) approach to classifying listening environments. This method is efficient and robust and well suited for hearing aid applications.
