1. 11. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

   Författare :Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation automation systems; IEC 61850; electrical topology; electrical engineering; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.

3. 12. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

   Författare :Gustaf Svedjemo; Erland Jungert; Wollter Arnberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia; Computer science; Datavetenskap; History subjects; Historieämnen;

   Sammanfattning : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. LÄS MER

4. 13. Road network and GPS tracking with data processing and quality assessment

   Författare :Xiaoyun Zhao; Johan Håkansson; Kenneth Carling; Bin Jiang; Högskolan Dalarna; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS tracking; Reliability; Road network; visualized map; road network; Map-matching; P-median Model; Network density; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : GPS technology has been embedded into portable, low-cost electronic devices nowadays to track the movements of mobile objects. This implication has greatly impacted the transportation field by creating a novel and rich source of traffic data on the road network. LÄS MER

5. 14. Att göra historia : En kritisk studie av historieämnet som kunskapsorganiserande system

   Författare :Per Nyström; Eva Hemmungs Wirtén; Birger Hjørland; Geir Vestheim.; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Classification systems; Social construction; Narratology; Historiography; Library and information science; Biblioteks- och informationsvetenskap; Biblioteks- och informationsvetenskap; Library and Information Science;

   Sammanfattning : The central theme of the present thesis is the history subject viewed as a knowledge organizing system (KOS). The history subject is studied as a class within the two universal classification systems SAB and DDC, where it is characterized by a conceptual intention and extension giving it a unique identity.

7. 15. Methods and Algorithms for Data-Intensive Computing : Streams, Graphs, and Geo-Distribution

   Författare :Hooman Peiro Sajjad; Vladimir Vlassov; Keijo Heljanko; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream processing; geo-distributed infrastructure; edge computing; streaming graph; dynamic graph; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

   Sammanfattning : Struggling with the volume and velocity of Big Data has attracted lots of interest towards stream processing paradigm, a paradigm in the area of data-intensive computing that provides methods and solutions to process data in motion. Today's Big Data includes geo-distributed data sources. LÄS MER
