1. 21. Parallel Data Streaming Analytics in the Context of Internet of Things

   Författare :Hannaneh Najdataei; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; clustering; stream continuous data processing; edge computing; Internet of Things; parallelism; elasticity; data analysis; fog computing; scalability;

   Sammanfattning : We are living in an increasingly connected world, where the ubiquitously sensing technologies enable inter-connection of physical objects, as part of Internet of Things (IoT), and provide continuous massive amount of data. As this growth soars, benefits and challenges come together, which requires development of right tools in order to extract valuable information from data. LÄS MER

3. 22. IT Service Delivery in Nicaraguan Internet Service Providers : analysis and Assessment

   Författare :Will Johnny Flores Delgadillo; Paul Johannesson; Lazar Rusu; Eva Söderström; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IT; service delivery; Internet service provider; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning :   The thesis addresses the research question: How to describe, understand, and explain IT service delivery? Based on the research question, the following research questions were derived:  How to analyse IT service delivery based on ITIL in order to determine its current situation? How to formalize elements of IT service delivery in maturity level that can be used to assess its current status? These research questions are answered by two IT artefacts: an analysis method and a maturity model for IT service delivery. Both of them are constructed by design-science research guidelines.

5. 24. Pathway analysis: methods and perspectives

   Författare :Gustavo Stolf Jeuken; Lukas Käll; Mika Gustafsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pathway analysis; mutual information; survival analysis; enrichment analysis; transcriptomics.; Biotechnology; Bioteknologi;

   Sammanfattning : The amount of data being generated by high throughput molecular biology experiments grows every day, both in quantity and quality. With this comes the desire to have more powerful and comprehensive methods for statistical analysis that have been developed with the nature of this data in mind. LÄS MER

7. 25. Data Modeling for Outlier Detection

   Författare :Shahrooz Abghari; Niklas Lavesson; Håkan Grahn; Veselka Boeva; Anders Holst; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data modeling; cluster analysis; stream data; outlier detection;

   Sammanfattning : This thesis explores the data modeling for outlier detection techniques in three different application domains: maritime surveillance, district heating, and online media and sequence datasets. The proposed models are evaluated and validated under different experimental scenarios, taking into account specific characteristics and setups of the different domains. LÄS MER
