4. 3. Performance Assessment of Long Combination Vehicles using Naturalistic Driving Data

   Författare :Abhijeet Behera; Sogol Kharrazi; Erik Frisk; Mats Jonasson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The deployment of long combination vehicles (LCVs) is currently in progress in Sweden. LCV refers to heavy vehicles that are longer than 25.25 m, which is the conventional length limit in Swedish regulations. LCVs reduce operational costs, improve fuel efficiency and reduce CO2 emission per ton-km. LÄS MER

5. 4. Analytics-driven approaches supporting asset management of sanitary sewer networks

   Författare :Emmanuel Okwori; Annelie Hedström; Maria Viklander; Marius Møller Rokstad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven; Decision Support; Network Robustness; VA-teknik; Urban Water Engineering;

   Sammanfattning : Sewer blockages can cause overflows and flooding, with consequences such as damage to property and environmental pollution, risks to public health and economic loss. Despite the causes being understood, blockages in sewer networks may occur unpredictably. LÄS MER

7. 5. An Emulation-Based Performance Evaluation Methodology for Edge Computing and Latency Sensitive Applications
