  1. 41. Efficient concurrent data structure access parallelism techniques for increasing scalability

    Författare :Adones Rukundo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FIFO queue; parallelism; performance modelling; design framework; semantic relaxation; Data structure; multi-access; lock free; performance analysis; counter; concurrency; search tree.; stack; multi-core processor; priority queue;

    Sammanfattning : Multi-core processors have revolutionised the way data structures are designed by bringing parallelism to mainstream computing. Key to exploiting hardware parallelism available in multi-core processors are concurrent data structures. LÄS MER

  3. 42. Models for Ordered Categorical Pharmacodynamic Data

    Författare :Per-Henrik Zingmark; Mats O Karlsson; E. Niclas Jonsson; France Mentré; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Pharmacodynamic; Modelling; Categorical data; NONMEM; Proportional odds model; Markov model; Differential drug effect model; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI;

    Sammanfattning : In drug development clinical trials are designed to investigate whether a new treatment is safe and has the desired effect on the disease in the target patient population. Categorical endpoints, for example different ranking scales or grading of adverse events, are commonly used to measure effects in the trials. LÄS MER

  4. 43. Towards an Ontology Design Pattern Quality Model

    Författare :Karl Hammar; Kurt Sandkuhl; Henrik Eriksson; Vladimir Tarasov; Eva Blomqvist; Arianit Kurti; Jönköping University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology; OWL; Ontology Design Pattern; Semantic Web; Quality Model;

    Sammanfattning : The use of semantic technologies and Semantic Web ontologies in particular have enabled many recent developments in information integration, search engines, and reasoning over formalised knowledge. Ontology Design Patterns have been proposed to be useful in simplifying the development of Semantic Web ontologies by codifying and reusing modelling best practices. LÄS MER

  5. 44. Data Importance in Power System Asset Management

    Författare :Wadih Naim; Patrik Hilber; Miroslav Begovic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data availability; data quality; asset management; power systems; maintenance optimization; Datatillgänglighet; datakvalitet; tillgångsförvaltning; kraftsystem; underhållsoptimering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The current shift towards a higher degree of data-driven decision making in power system asset management highlights the importance of asset data. This thesis identifies, investigates, and proposes methods for data-related research gaps that are encountered by asset managers. These research gaps are in data availability and data quality.

  7. 45. Integrating multi-omics for type 2 diabetes : Data science and big data towards personalized medicine

    Författare :Klev Diamanti; Jan Komorowski; Claes Wadelius; Manfred Grabherr; Peter Spégel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes; multi-omics; genomics; metabolomics; data science; machine learning; personalized medicine; Bioinformatics; Bioinformatik;

    Sammanfattning : Type 2 diabetes (T2D) is a complex metabolic disease characterized by multi-tissue insulin resistance and failure of the pancreatic β-cells to secrete sufficient amounts of insulin. Cells recruit transcription factors (TF) to specific genomic loci to regulate gene expression that consequently affects the protein and metabolite abundancies. LÄS MER
