1. 1. Regressor and Structure Selection : Uses of ANOVA in System Identification

   Författare :Ingela Lind; Lennart Ljung; Torsten Söderström; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Regressor selection; Analysis of variance; Nonlinear systems; Structure selection; Automatic control; Reglerteknik;

   Sammanfattning : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. LÄS MER

3. 2. Characterization of crystalline materials by rotation electron diffraction : Phase identification and structure determination

   Författare :Yifeng Yun; Xiaodong Zou; Christian W. Lehmann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; phase identification; rotation electron diffraction; structure determination; three-dimensional electron diffraction; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Electron crystallography is powerful for determination of complex structures. The newly-developed 3D electron diffraction (ED) methods make structure determination from nano- and micron-sized crystals much easier than using other methods, for example X-ray diffraction. LÄS MER

4. 3. Hidden Markov models : Identification, control and inverse filtering

   Författare :Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

5. 4. On-Line Structure Selection for the Identification of Multivariable Systems

   Författare :A J M van Overbeek; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-line structure; Identification; Multivariable systems;

   Sammanfattning : An algorithm is described for the selection of mod el structure for identifying multivariable mode Is of"black box" character. The algorithm receives as "input" a mode I in a given parametrization (= mode I structure). It is then tested whether this parametrization is suitable (well conditioned) for identification purposes.

7. 5. A Study in RNA Bioinformatics : Identification, Prediction and Analysis

   Författare :Eva Freyhult; David Ardell; Robert Giegerich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; bioinformatics; secondary structure; structure prediction; dynamic programming; energy landscape; homology search; sequence logo; tRNA; Bioinformatics; Bioinformatik;

   Sammanfattning : Research in the last few decades has revealed the great capacity of the RNA molecule. RNA, which previously was assumed to play a main role only as an intermediate in the translation of genes to proteins, is today known to play many important roles in the cell in addition to that as a messenger RNA and transfer RNA, including the ability to catalyze reactions and gene regulations at various levels.
