  1. 21. Hidden Markov models : Identification, control and inverse filtering

    Author : Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 22. Characterization and optimization of the in vitro motility assay for fundamental studies of myosin II

    Author : Malin Persson; Alf Månsson; Carlo Reggiani; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Myosin II; skeletal muscle; actomyosin; in vitro motility assay; protein adsorption; cargo transportation; CapZ; cross-bridge cycle; inter-head cooperativity; processivity; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : Myosin II is the molecular motor responsible for muscle contraction. It transforms the chemical energy in ATP into mechanical work while interacting with actin filaments in so called cross-bridge cycles. Myosin II or its proteolytic fragments e.g. READ MORE

  3. 23. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models

    Author : Nasser Mohammadiha; Arne Leijon; W. Bastiaan Kleijn; Cédric Févotte; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech enhancement; noise reduction; nonnegative matrix factorization; hidden Markov model; probabilistic latent component analysis; online dictionary learning; super-Gaussian distribution; MMSE estimator; temporal dependencies; dynamic NMF;

    Abstract : Reducing interference noise in a noisy speech recording has been a challenging task for many years yet has a variety of applications, for example, in handsfree mobile communications, in speech recognition, and in hearing aids. Traditional single-channel noise reduction schemes, such as Wiener filtering, do not work satisfactorily in the presence of non-stationary background noise. READ MORE

  4. 24. Hidden Markov models - Traffic modeling and subspace methods

    Author : Sofia Andersson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; operationsanalys; Statistics; operations research; subspace identification; state space representation; likelihood estimation; Poissonification; traffic analysis; hidden Markov model; Markov-modulated Poisson process; programmering; aktuariematematik;

    Abstract : The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. READ MORE

  5. 25. Variation in length of proteins by repeats and disorder regions

    Author : Rauan Sagit; Arne Elofsson; Andrey Kajava; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein length; repeats; domain repeats; protein evolution; duplication; tandem duplication; intrinsic disorder; intrinsically disordered; variation in length; insertion; deletion; recombination; expansion; contraction; Biochemistry; biokemi;

    Abstract : Protein-coding genes evolve together with their genome and acquire changes, some of which affect the length of their protein products. This explains why equivalent proteins from different species can exhibit length differences. READ MORE
