  1. 21. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

    Författare :Christian Rosén; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektroteknik; Electrical engineering; wastewater treatment; supervisory control; simulation; process monitoring; principal component analysis PCA ; multivariate statistics; modelling; activated sludge; detection; control engineering; Automatiska system; robotteknik; reglerteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

  3. 22. On Spectral Estimation and Bistatic Clutter Suppression in Radar Systems

    Författare :Jacob Klintberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radar Signal Processing; Parametric Spectral Estimation; Maximum Likelihood Estimation; Space-Time Adaptive Processing;

    Sammanfattning : Target detection serve as one of the primary objectives in a radar system. From observations, contaminated by receiver thermal noise and interference, the processor needs to determine between target absence or target presence in the current measurements. LÄS MER

  4. 23. On Money and Consumption

    Författare :Erik Öberg; Per Krusell; Marco Bassetto; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; nationalekonomi;

    Sammanfattning : Price Level Determination When Tax Payments Are Required in Money. We formalize the idea that the price level can be determined by a requirement that taxes be paid in money. LÄS MER

  5. 24. Water supply in hard rock coastal regions : The effect of heterogeneity and kinematic porosity

    Författare :Robert Earon; Bo Olofsson; Gerhard Barmen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal aquifer; Crystalline rock; Water balance; Geographic information systems; Water supply planning;

    Sammanfattning : Water resources in hard rock terrain are difficult to characterize due to heterogeneity and anisotropy in the fracture network, low porosities and limited recharge volumes available during the summer season. Three methods were developed and evaluated in order to assist in water supply planning. LÄS MER

  7. 25. Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates

    Författare :Jesper Hansson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; Economics; Real exchange rate; Public debt; Structural VAR model; Cointegration; Habits; Permanent income hypothesis PIH ; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : Advances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate.
