1. 16. Strategic Design of Multi-Actor Nascent Energy and Industrial Infrastructure Networks under Uncertainty

   Författare :Yeshambel Melese; Paulien Herder; Rob Stikkelman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Infrastructure networks, such as gas transmission and distribution pipelines, electricity transmission and distribution cables, district heating networks and carbon capture and storage pipeline networks are vital infrastructures that form the backbone of our energy system. They transport commodities (i.e. LÄS MER

3. 17. Hydraulic transport of mineral and ore products : friction losses of stratified flows at high solids concentrations

   Författare :Åsa Sundqvist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Sammanfattning : The overall objective of the work presented in this thesis was to investigate the hydraulic transport of mineral and ore products with regard to friction losses in horizontal pipelines at high solids concentrations. In detail, the objectives are to present and examine experimental pilotscale and large-scale friction loss results, and to investigate the performance of a scaling relationship for stratified slurry flows with regard to the effects of pipe diameter and solids concentration.

4. 18. Numerical modelling considerations for analysis of concrete hydraulic structures subjected to high-frequency seismic loads

   Författare :Roghayeh Abbasiverki; Anders Ansell; Erik Nordström; Richard Malm; Peter Folkow; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betongbyggnad; Concrete Structures;

   Sammanfattning : Concrete hydraulic structures are of great importance in today's society. When situated in areas with hard bedrock, these structures may become extra vulnerable to seismic excitations as these here are dominated by high-frequency vibrations which can have disastrous consequences for slender structures.

5. 19. Scalable and Reliable Data Stream Processing

   Författare :Paris Carbone; Seif Haridi; Peter Pietzuch; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; stream processing; data management; databases; distributed computing; data processing; fault tolerance; database optimisation; programming systems; data science; data analytics; computer science; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Data-stream management systems have for long been considered as a promising architecture for fast data management. The stream processing paradigm poses an attractive means of declaring persistent application logic coupled with state over evolving data. LÄS MER

7. 20. Bioinformatic screening for candidate mutations underlying phenotypic traits in domestic animals

   Författare :Shumaila Sayyab; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Domestic animals represent excellent model organisms for gene mapping and identification of mutations underlying phenotypic traits. Humans have selected spontaneous mutations in farm and companion animals since they were domesticated and this has resulted in large phenotypic variation among different breeds. LÄS MER
