    Författare :Kaushik Mahata; Torsten Söderström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Sammanfattning : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. LÄS MER

  3. 22. On Multivariable and Nonlinear Identification of Industrial Robots

    Författare :Erik Wernholt; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The main objective of the thesis is the identification of flexibilities and nonlinearities in mathematical models of industrial robots. In particular, a nonparametric frequency-domain estimation method for the multivariable frequency response function (MFRF) has been evaluated and analyzed for the robot application. LÄS MER

  4. 23. Structural Control and Identification of Civil Engineering Structures

    Författare :Tarek Edrees; Francesc Pozo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : In general, the main purpose of a structural control system is to apply powerful control techniques that improve the behaviour of civil structures under various kinds of dynamic loading. The first part of this thesis presents novel applications of posicast and input shaping control schemes that have never previously been applied in the field of structural control. LÄS MER

  5. 24. Hereditary Colorectal Cancer; Identification, Characterization and Classification of Mutations

    Författare :Anna Rohlin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hereditary Colorectal cancer; FAP; AFAP; mutations; mosaic mutation; exome sequencing; massively parallel sequencing; next generation sequencing; atypical polyposis; APC; POLE; GREM1; PPAP;

    Sammanfattning : Hereditary factors are thought to play are role in 20-30% of all colorectal cancers Around 6% are found as high penetrant disease-causing mutations in genes correlated to hereditary polyposis or hereditary non-polyposis syndromes. The aim of this thesis was to identify new causative genes and variants and also mutation mechanisms in families presenting a polyposis, atypical polyposis or nonpolyposis CRC phenotype. LÄS MER

  7. 25. Optimal input design for nonlinear dynamical systems : a graph-theory approach

    Författare :Patricio E. Valenzuela Pacheco; Cristian R. Rojas; Roland Hildebrand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input design; Markov chains; system identification; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Optimal input design concerns the design of an input sequence to maximize the information retrieved from an experiment. The design of the input sequence is performed by optimizing a cost function related to the intended model application. Several approaches to input design have been proposed, with results mainly on linear models. LÄS MER
