2. 16. 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

4. 17. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

   Author : Anton Albinsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

   Abstract : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. READ MORE

5. 18. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

   Author : Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

   Abstract : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. READ MORE

6. 19. Estimation and detection of transmission line characteristics in the copper access network

   Author : Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

   Abstract : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. READ MORE

7. 20. DSGE Model Estimation and Labor Market Dynamics

   Author : Glenn Mickelsson; Nils Gottfries; Karl Walentin; Martin M Andreasen; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; DSGE Models; Macroeconomics; Estimation; Uninformative Priors; Maximum Likelihood; Labor Hoarding; US Labor Market; Swedish Micro Data; Economics; Nationalekonomi;

   Abstract : Essay 1: Estimation of DSGE Models with Uninformative PriorsDSGE models are typically estimated using Bayesian methods, but because prior information may be lacking, a number of papers have developed methods for estimation with less informative priors (diffuse priors). This paper takes this development one step further and suggests a method that allows full information maximum likelihood (FIML) estimation of a medium-sized DSGE model. READ MORE
