1. 1. Road traffic metals : sources and emissions

   Författare :David Hjortenkrans; Bo Bergbäck; Per-Arne Malmqvist; Högskolan i Kalmar; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

   Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER

3. 2. Network-based Anomaly Detection for SCADA Systems : Traffic Generation and Modeling

   Författare :Chih-Yuan Lin; Simin Nadjm-Tehrani; Mikael Asplund; Aditya P. Mathur; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open standards and being connected to the Internet to enable remote control. LÄS MER

4. 3. Virtual Human Characters for Autonomous Vehicle-to-Pedestrian Communication

   Författare :Alexandros Rouchitsas; Håkan Alm; Jessica Körning-Ljungberg; Jonas Lundberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; external human-machine interfaces; pedestrian acknowledgement; vehicle intention; traffic safety; traffic flow; gaze direction; facial expression; Engineering Psychology; Teknisk psykologi;

   Sammanfattning : Pedestrians base their street-crossing decisions on both vehicle-centric cues, like speed and acceleration, and driver-centric cues, like gaze direction and facial expression. In the future, however, drivers of autonomous vehicles will be preoccupied with non-driving related activities and thus unavailable to provide pedestrians with relevant communicative cues. LÄS MER

5. 4. An evaluation of sources contributing to urban runoff pollution

   Författare :Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER

7. 5. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface

   Författare :Mattias Bäckström; Gunnar Jacks; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lead; trace elements; traffic; shooting range; peat; sediments; speciation; biokemi; Chemistry; Kemi; Kemi; Chemistry;

   Sammanfattning : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. LÄS MER
