1. 1. Sense of Touch in Robots

   Författare :Magnus Johnsson; Kognitionsvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; touch perception; neural network; robot hand; brain model; cognitive model; robot model; tensor network; associative self-organizing map; SOM; proprioception;

   Sammanfattning : This thesis discusses a number of robot touch perception systems. All these systems are self-organizing and model different aspects of human touch perception. The thesis starts out with introductions to the anatomy and the physiology of the human hand. LÄS MER

3. 2. Mapping the proteome with data-driven methods: A cycle of measurement, modeling, hypothesis generation, and engineering

   Författare :Filip Buric; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tensor factorization; mass spectrometry; model interpretation; sequence feature engineering; deep learning; proteomics; machine learning; data-independent acquisition; feature learning;

   Sammanfattning : The living cell exhibits emergence of complex behavior and its modeling requires a systemic, integrative approach if we are to thoroughly understand and harness it. The work in this thesis has had the more narrow aim of quantitatively characterizing and mapping the proteome using data-driven methods, as proteins perform most functional and structural roles within the cell.

4. 3. Morphological alterations in frontotemporal dementia

   Författare :Alexander Santillo; Klinisk minnesforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; frontotemporal dementia; diffusion tensor imaging; von Economo neurons;

   Sammanfattning : The present thesis explores alterations in brain morphology in the neurodegenerative disorder of frontotemporal dementia (FTD). With the aim to improve the clinical diagnostics of FTD, we explored the diagnostic potential of measuring morphological alterations in the white matter by diffusion tensor imaging (DTI)- MRI, compared with the more commonly used assessment of grey matter thickness and volume.

5. 4. Earthquake Sources, the Stress Field and Seismic Hazard : A Study in Eritrea and its Surrounding

   Författare :Lijam Zemichael Hagos; Roland Roberts; Hossein Shomali; Kuvvet Atakan; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Seismic hazard; Focal mechanism; Moment tensor inversion; Stress field; Afar depression; Eritrea; Geovetenskap; Earth sciences; Geovetenskap;

   Sammanfattning : Presented in this thesis are some basic concepts and applications of seismic hazard analysis and the elements that influence the amplitude and geometric attenuation of earthquake ground motion. This thesis centers on the identification of the styles of failure, focal mechanisms, and the state of regional stress in the study area. LÄS MER

7. 5. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

   Författare :Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

   Sammanfattning : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.
