  1. 1. Spatial analysis and modeling of nerve fiber patterns

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Claes Andersson; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian field theory; Diabetic neuropathies; Multilevel models Statistics ; Institutionen för matematiska vetenskaper. Tillämpad matematik och statistik.; CTH; hierarchical models; Bayesian estimation; epidermal nerve fibers; cluster processes; spatial point processes; diabetic neuropathy;

    Abstract : Diabetic neuropathy is a condition associated with diabetes affecting the epidermal nerve fibers (ENFs). This thesis presents analysis methods and models for ENF data, with two main puroposes: to find early signs of diabetic neuropathy and to characterize how this condition changes the nerve fiber structure.

  2. 2. Structures in High-Dimensional Data: Intrinsic Dimension and Cluster Analysis

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Kerstin Johnsson; [2016-08-16]

    Abstract : With today's improved measurement and data storing technologies it has become common to collect data in search for hypotheses instead of for testing hypotheses---to do exploratory data analysis. Finding patterns and structures in data is the main goal. READ MORE

  3. 3. Characteristics of Self-Injury in Young Adolescents: Findings from Cross-Sectional and Longitudinal Studies in Swedish Schools

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Jonas Bjärehed; [2012]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-suicidal self-injury; NSSI; Deliberate self-harm; DSH; Adolescents; cluster analysis;

    Abstract : Self-injury in adolescents (e.g. when individuals cut, burn, hit or otherwise deliberately cause themselves direct injury), has gained recognition as a potentially important mental health problem during the past decade. Relatively little has been known about the scope and characteristics of this behavior in Swedish adolescents. READ MORE

  4. 4. Directed Evolution of Glutathione Transferases Guided by Multivariate Data Analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sanela Kurtovic; Uppsala universitet.; [2008]
    Keywords : Biochemistry; DNA shuffling; substrate selectivity; mutant library; glutathione transferase; multivariate data analysis; prodrug; Biokemi;

    Abstract : Evolution of enzymes with novel functional properties has gained much attention in recent years. Naturally evolved enzymes are adapted to work in living cells under physiological conditions, circumstances that are not always available for industrial processes calling for novel and better catalysts.

  5. 5. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

    University dissertation from Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Bin Wang; Xiaodong Zou; Andy Stewart; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; oorganisk kemi; Inorganic Chemistry;

    Abstract : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects. READ MORE
