1. 11. Probabilistic Sequence Models with Speech and Language Applications

   Författare :Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

   Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER

3. 12. On the Design of Communication Systems for Strong Oscillator Phase Noise - Detection Methods and Constellation Optimization

   Författare :Rajet Krishnan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum a posteriori MAP estimation; constellations; phase noise; maximum likelihood ML detection; Oscillator; symbol error probability; extended Kalman filter EKF ; mutual information.;

   Sammanfattning : The problem of designing wireless communication systems to operate in the presence of oscillator phase noise is a classical problem in communication theory. In recent times, there has been a renewed interest in thisproblem for a multitude of reasons. LÄS MER

4. 13. Power to the people : electricity demand and household behavior

   Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

   Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

5. 14. Models of Electoral Competition : Three Essays on Political Economics

   Författare :Jan Klingelhöfer; Torsten Persson; Christian Schultz; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Elections; Lobbying; Rents; Imperfect Information; Median Voter Theorem; Accountability; Valence; Economics; Nationalekonomi; Economics; nationalekonomi;

   Sammanfattning : This thesis consists of three essays in theoretical political economics. In "The Swing Voters' Blessing", I model elections with quality differences between two ideological candidates. The quality differences are only observable to a limited number of informed voters. LÄS MER

7. 15. Essays on Fiscal Policy, Public Debt and Financial Development

   Författare :Alfredo Schclarek Curutchet; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; private consumption; Ekonomisk planering; Handel; Economic planning; imperfect information; Trade; financial development; economic growth; capital accumulation; productivity growth; private savings rate; vertical innovation; horizontal innovation; industry diversification; public debt; external debt; developing countries; taxation; government expenditure; fiscal policy;

   Sammanfattning : This thesis consists of three distinct articles that can be read separately. Each one has been awarded a chapter of its own. The independence of these chapters should not be taken as meaning that they are unrelated. Besides belonging all to the subfield of macroeconomics, they share the common feature of being inherently economic policy oriented. LÄS MER
