  1. 1. Improved remaining useful life estimations for on-condition parts in aircraft engines

    University dissertation from Skövde : University of Skövde

    Author : Veronica Fornlöf; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aircraft engine maintenance; Reliability; Remaining useful life; On-condition parts; Prognosis; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : This thesis focuses on obtaining better estimates of remaining life for on-condition (OC) parts in aircraft engines. Aircraft engine components are commonly classified into three categories, life-limited parts (LLP), OC-parts and consumables. Engine maintenance typi-cally accounts for 10% to 20% of aircraft-related operating cost. READ MORE

    Abstract : This thesis consists of four manuscripts in the area of nonlinear time series econometrics on topics of testing, modeling and forecasting nonlinear common features. The aim of this thesis is to develop new econometric contributions for hypothesis testing and forecasting in thesearea.Both stationary and nonstationary time series are concerned. READ MORE

  3. 3. Time-Series Econometrics Applied to Macroeconomic Issues

    University dissertation from Jönköping : Internationella Handelshögskolan

    Author : Abdulnasser Hatemi-J; Högskolan i Jönköping.; [2001]
    Keywords : ;

    Abstract : This doctoral dissertation is a collection of six articles. Special attention is paid to model specification and the time-series properties of the data applied in each case. The first two articles deal with fiscal policy in Sweden and the effects of EMU criteria convergence. READ MORE

  4. 4. Amoebas and Laurent series

    University dissertation from Stockholm : Matematik

    Author : Mikael Forsberg; KTH.; [1998]
    Keywords : ;

    Abstract : The amoeba of a polynomialpis the logarithmic image of the zero set of thepolynomial. l/pcan be developed into several Laurent series. Thelogarithmic image of every such Laurent series have a domain ofconvergence and its loga rithmic image is a component of thecomplement of the amoeba of p. This is the background for thethesis subjett. READ MORE

  5. 5. Essays on Time Series Analysis With Applications to Financial Econometrics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Preve; Uppsala universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian time series; nonnegative autoregression; robust estimation; strong convergence; realized volatility; volatility forecast; forecast comparison; Diebold-Mariano test; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik;

    Abstract : This doctoral thesis is comprised of four papers that all relate to the subject of Time Series Analysis.The first paper of the thesis considers point estimation in a nonnegative, hence non-Gaussian, AR(1) model. The parameter estimation is carried out using a type of extreme value estimators (EVEs). READ MORE
