  1. 36. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

    Författare :Ulrik Egede; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

    Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER

  3. 37. Approximations of Bayes Classifiers for Statistical Learning of Clusters

    Författare :Magnus Ekdahl; Timo Koski; Jukka Corander; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pattern Recognition; Stochastic Complexity; Naïve Bayes; Bayesian Network; Classification; Clustering; Chow-Liu trees; Mathematical statistics; Matematisk statistik;

    Sammanfattning : It is rarely possible to use an optimal classifier. Often the classifier used for a specific problem is an approximation of the optimal classifier. Methods are presented for evaluating the performance of an approximation in the model class of Bayesian Networks. LÄS MER

  4. 38. Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution

    Författare :Mike Gerdes; Diego Galar; Uday Kumar; Dieter Scholz; Piotr Bilski; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition Monitoring; Remaining Useful Life Prediction; Decision Tree; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring; Feature Extraction; Feature Selection; Data Driven; Health Prognostic; Knowledge Based System; Supervised Learning; Data-Driven Predictive Health Monitoring; Health Indicators; Machine Learning; Big Data; Pattern Recognition; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Reducing unscheduled maintenance is important for aircraft operators. There are significant costs if flights must be delayed or cancelled, for example, if spares are not available and have to be shipped across the world. LÄS MER

  5. 39. Computational biology of blood disorders: Patterns and algorithms

    Författare :Björn Nilsson; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical genetics; Klinisk genetik; Image analysis; Ontological analysis; Pattern recognition; Gene expression profiling; Microarrays; Hematologic malignancies; Acute leukemia; Chronic myeloid leukemia;

    Sammanfattning : The morphological and molecular characterization and of malignant blood disorders is pivotal to ensure a correct diagnosis, guide therapy, and, in the longer term, to identify their molecular causes. Over the past several years, new technology has increased our abilities to describe, typecast, and understand hematologic malignancies beyond what was previously possible. LÄS MER

  7. 40. Towards Automatic Image Analysis for Computerised Mammography

    Författare :Christina Olsén; Frank Drewes; Fredrik Georgsson; Gunilla Borgefors; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Aided Diagnosis; Quality Assessment; Image Analysis; Ground Truth Assessment; Artificial Intelligence; Measurements; Segmentation Evaluation; Performance Measures; Pattern Recognition; Validation; Decision Support; Medicine; Computer science; Datavetenskap;

    Sammanfattning : Mammographic screening is an effective way to detect breast cancer. Early detection of breast cancer depends to a high degree on the adequacy of the mammogram from which the diagnosis is made. Today, most of the analysis of the mammogram is performed by radiologists. LÄS MER
