   Författare :Lotta Dessen Jankell; Inger Eriksson; Patrik Johansson; Elin Sæther; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; systems thinking; geography teaching; system geographical knowing; system modelling; education for sustainable development; connection web models; system changes; learning activity; practice theory; learning models; geography didactics; systemtänkande; sambandsvävar; geografiundervisning; systemgeografiskt kunnande; systemmodeller; klimatförändringar; hållbar utveckling; ämnesdidaktik med inriktning mot de samhällsvetenskapliga ämnenas didaktik; Teaching and Learning with Specialisation in the Social Sciences Education;

   Sammanfattning : This doctoral thesis is concerned with how upper secondary students in Sweden develop system geographical knowing through Geography teaching, where complex issues such as climate change are dealt with. In many countries, these issues are particularly relevant for the school subject of Geography since the subject is responsible for issues that involve system changes. LÄS MER

4. 3. Uncertainties in Neural Networks : A System Identification Approach

   Författare :Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

   Sammanfattning : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. LÄS MER

5. 4. Final Approach : Measurements and Ratings of Aircraft Landing Noise

   Författare :Anders Johansson; Karl Bolin; Susann Boij; Antonio Filippone; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft noise; acoustic measurements; psycho acoustics measurements; noise annoyance; Flygplansbuller; akustiska mätningar; psykoakustiska mätningar; bullerstörning; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Följande avregleringen av flygmarknaden har flygtrafiken ökat snabbt sedan mitten av 1990-talet. Detta har oundvikligen lett till en utbyggnad av flygplatser, vilket på många platser runt om i världen har lett till oro och konflikter på grund av ökade bullernivåer. LÄS MER

7. 5. A System of Systems View in Early Product Development : An Ontology-Based Approach

   Författare :Ludvig Knöös Franzén; Petter Krus; Christopher Jouannet; Ingo Staack; Kristian Amadori; Daniel DeLaurentis; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Systems Engineering; Ontology; Description Logic Reasoning; Design Space Exploration; Aircraft Design; Search and Rescue; Early Product Development;

   Sammanfattning : The concept of system-of-systems is becoming increasingly common and relevant in many engineering applications. Today’s highly interconnected world entails that more and more systems have dependencies on other systems. LÄS MER
