6. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models
Sammanfattning : 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. LÄS MER
7. Segmentation of Laser Range Radar Images using Hidden Markov Field Models
Sammanfattning : Segmentation of images in the context of model based stochastic techniques is connected with high, very often unpracticle computational complexity. The objective with this thesis is to take the models used in model based image processing, simplify and use them in suboptimal, but not computationally demanding algorithms. LÄS MER
8. Hidden Markov models for remote protein homology detection
Sammanfattning : Genome sequencing projects are advancing at a staggering pace and are daily producing large amounts of sequence data. However, the experimental characterization of the encoded genes and proteins is lagging far behind. LÄS MER
9. Rainflow Analysis of Switching Markov Loads
Sammanfattning : Rainflow cycles are often used in fatigue analysis of materials for describing the variability of applied loads. Therefore, an important characteristic of a random load process is the intensity of rainflow cycles, also called the expected rainflow matrix (RFM), which can be used for evaluation of the fatigue life.

10. Predicting transmembrane topology and signal peptides with hidden Markov models
Sammanfattning : Transmembrane proteins make up a large and important class of proteins. About 20% of all genes encode transmembrane proteins. They control both substances and information going in and out of a cell. LÄS MER
