  2. 6. Parameter Estimation - in sparsity we trust

    Author : Johan Swärd; Statistical Signal Processing Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; Sparse models; Convex optimization; Symbolic Periodicity; Alternating direction method of multipliers ADMM ; Covariance fitting; multi-pitch estimation problem; Off-grid estimation; Dictionary learning; Atomic norm; Sampling schemes;

    Abstract : This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. READ MORE

  4. 7. Risk Management in Tunneling Projects : Estimation and Planning

    Author : Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Stefan Larsson; Anna Kadefors; Amund Bruland; KTH; []
    Keywords : Cost overrun; Transport infrastructure projects; Time and cost estimation; Probabilistic approaches; Tunneling; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Cost overruns and schedule delays are frequently observed occurrences in the construction of transport infrastructure projects. Such phenomena lead to the mismanagement of significant amounts of both public and private resources. READ MORE

  5. 8. Channel Estimation in Wireless Communication Systems Employing Multiple Antennas

    Author : Mikael Coldrey; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; capacity; channel estimation; non-parametric estimation; training; distributed sources; MIMO; Wireless communications; superimposed pilots; performance bounds;

    Abstract : Antennas that are able to adaptively direct the transmitted (and received) energy are of great interest in future wireless communication systems. The directivity implies reduced transmit power and interference, and also a potential for increased capacity. READ MORE

  6. 9. Automation of front-end loaders : electronic self leveling and payload estimation

    Author : I Yung; Leonid Freidovich; Sven Rönnbäck; Carlos Vázquez; Tomas Nygren; Heikki Handroos; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Front-End Loaders; Electronic Self Leveling; Modeling; Control; Disturbance estimation; Payload estimation; Equations of motion; Pressure-based friction;

    Abstract : A growing population is driving automatization in agricultural industry to strive for more productive arable land. Being part of this process, this work is aimed to investigate the possibility to implement sensor-based automation in a particular system called Front End Loader, which is a lifting arms that is commonly mounted on the front of a tractor.

  7. 10. Estimation Using Low Rank Signal Models

    Author : Kaushik Mahata; Torsten Söderström; Mats Viberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; separable least squares; statistical analysis; viscoelasticity; subspace algorithms; spectrum estimation; Signal processing; Signalbehandling;

    Abstract : Designing estimators based on low rank signal models is a common practice in signal processing. Some of these estimators are designed to use a single low rank snapshot vector, while others employ multiple snapshots. This dissertation deals with both these cases in different contexts. READ MORE
