1. 6. 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. 7. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams

   Författare :Hamza Benmakhlouf; Pedro Andreo; Klemens Zink; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Backscatter factors; Diagnostic radiology dosimetry; Mass energy-absorption coefficients; Monte Carlo; Output correction factors; Radiotherapy dosimetry; Reference dosimetry; Relative dosimetry; Small photon fields; Medical Radiation Physics; medicinsk strålningsfysik;

   Sammanfattning : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.

4. 8. An insight into the metabolism of New Psychoactive Substances : Structural elucidation of urinary metabolites of synthetic cannabinoids and fentanyl analogues using synthesized reference standards

   Författare :Jakob Wallgren; Johan Dahlén; Peter Konradsson; Xiongyu Wu; Mogens Johannsen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. LÄS MER

5. 9. Manufacturing system data management and development : towards a STEP compliant reference model for manufacturing

   Författare :Mattias Larsson; Torsten Kjellberg; Anders Dannstedt; KTH; []
   Nyckelord :Information Management; Industrial Engineering; Collaborative Engineering;

   Sammanfattning : Collaborative engineering assumes a common understanding of the domain. To make joint decisions the engineers must have a common language to start from. Standards such as STEP may be used to communicate engineering data but to speak about information integration and interoperability there must be ways to expose and share concepts as well. LÄS MER

7. 10. Development of Industrial Information Systems based on Standards

   Författare :Jonas Rosén; Torsten Kjellberg; Fumihiko Kimura; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Manufacturing engineering; Produktionsteknik; Information technology; Informationsteknik;

   Sammanfattning : This thesis has studied how ISO STEP application protocols can be used as a base for development of enterprise information systems that provides information sharing capabilities in a collaborative environment. In this thesis, five papers have been selected and are presented in the context of four themes that characterize the whole research body. LÄS MER
