2. 1. Bayesian Modeling of Directional Data with Acoustic and Other Applications

   Author : Jalil Taghia; Arne Leijon; W. Bastiaan Kleijn; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directional statistics; directional distributions; axial distributions; von Mises-Fisher distribution; complex Watson distribution; complex Bingham distribution; Bayesian inference; probabilistic modeling; variational inference; two-dimensional hidden Markov models; Markov chain; blind source separation; frequency domain BSS; underdetermined BSS; online BSS; Bayesian recursive; gene expression data; gene-microarray data; line spectral frequency; speaker identification. ii;

   Abstract : A direction is defined here as a multi-dimensional unit vector. Such unitvectors form directional data. Closely related to directional data are axialdata for which each direction is equivalent to the opposite direction.Directional data and axial data arise in various fields of science. READ MORE

4. 2. Functional aspects of tactile directional sensibility

   Author : Helena Backlund; Göteborgs universitet; []
   Keywords : Human; directional sensibility; hairy skin; hemispherectomy; postural control; glabrous skin; fMRI; psychophysics;

   Abstract : Tactile directional sensibility, i.e. the ability to tell the movement direction of a moving tactile stimulus, depends on the parallel processing of spatiotemporal information and information about changes in the pattern of skin tension. READ MORE

5. 3. Self-Normalized Sums and Directional Conclusions

   Author : Fredrik Jonsson; Allan Gut; Josef Steinebach; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-normalized sums; heavy-tailedness; Student s t-statistic; distributional symmetry; exponential tilting; directional conclusions; reversal rates; multiple statistical inference; the Benjamini-Hochberg procedure;

   Abstract : This thesis consists of a summary and five papers, dealing with self-normalized sums of independent, identically distributed random variables, and three-decision procedures for directional conclusions. In Paper I, we investigate a general set-up for Student's t-statistic. READ MORE

6. 4. Infrared Emittance of Paper : Method Development, Measurements and Application

   Author : Caroline Hyll; Lars Mattsson; Hannes Vomhoff; Carl-Gustaf Ribbing; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emittance; Emissivity; Thermography; Paper; Sheet; Papermaking; Paper mechanics; Moisture; Material properties; Reflectance; Transmittance; Absorptance; Infrared; Mid-wavelength infrared; MWIR; Long-wavelength infrared; LWIR; Angle-resolved; Directional;

   Abstract : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. READ MORE
