1. 11. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport

   Författare :Ahmet Mandev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; greenhouse gas GHG emissions; charging behavior; fuel consumption; eVKT; eVMT; PHEV Plug-in hybrid electric vehicle ; utility factor;

   Sammanfattning : The Paris Agreement emphasizes the importance of greenhouse gas mitigation in the transport sector to address climate change and create a sustainable future with lower carbon emissions. Plug-in hybrid electric vehicles (PHEVs) can be helpful in reducing greenhouse gas emissions in transportation when combined with efforts to decarbonize the electricity sector. LÄS MER

3. 12. Computational Methods for Optimal Control of Hybrid Systems

   Författare :Sven Hedlund; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; control engineering; robotteknik; Automatiska system;

   Sammanfattning : This thesis aims to find algorithms for optimal control of hybrid systems and explore them in sufficient detail to be able to implement the ideas in computational tools. By hybrid systems is meant systems with interacting continuous and discrete dynamics. Code for computations has been developed in parallel to the theory. LÄS MER

4. 13. A Multi-Dimensional Approach to Human Mobility and Transportation Mode Detection Using GPS Data

   Författare :Paria Sadeghian; Johan Håkansson; Xiaoyun Zhao; Mengjie Han; Kevin Heaslip; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transport mode detection; Machine learning; Statistical learning; Rule-based method; Data labelling;

   Sammanfattning : GPS tracking data is an essential resource for analyzing human travel patterns and evaluating the effects on transportation systems. The primary challenge, however, is to accurately identify the modes of transportation within unlabeled GPS data. These approaches range from simple rule-based systems to advanced machine-learning techniques. LÄS MER

5. 14. Hybrid microscopic-mesoscopic traffic simulation

   Författare :Wilco Burghout; Karl-Lennart Bång; Jaime Barceló; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorsystem; Datorsystem; Computer engineering; Datorteknik;

   Sammanfattning : Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of complicated traffic facilities and Intelligent Transportation Systems that often consist of complex traffic management, safety and information systems.

7. 15. Planning and Control of Cooperative Multi-Agent Manipulator-Endowed Systems

   Författare :Christos Verginis; Dimos V. Dimarogonas; Pedro Lima; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-agent systems; Temporal logics; Cooperative manipulation; Motion planning; Control; Navigation; Action planning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Multi-agent planning and control is an active and increasingly studied topic of research, with many practical applications, such as rescue missions, security, surveillance, and transportation. More specifically, cases that involve complex manipulator-endowed systems  deserve extra attention due to potential complex cooperative manipulation tasks and their interaction with the environment.
