  2. 1. Dynamic Modelling of Transit Operations and Passenger Decisions

    Author : Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

    Abstract : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. READ MORE

  4. 2. The Tail Assignment Problem

    Author : Mattias Grönkvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hybrid optimization; fleet planning; aircraft routing; column generation; airline optimization; tail assignment; constraint programming;

    Abstract : The Aircraft Assignment problem is the problem of assigning flights to aircraft in such a way that some operational constraints are satisfied, and possibly that some objective function is optimized.We propose an approach to aircraft assignment which captures all operational constraints, including minimum connection times, airport curfews, maintenance, and preassigned activities.

  5. 3. Lignin Model Compounds: Synthesis, Stereochemistry and Acidolysis

    Author : Shiming Li; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boric acid complexes; Arylglycerol b-aryl ethers; stereochemistry; 3-Diaryl-2-propen-1-ols; 1; Phenylcoumarans; lignin model compounds; acidolysis; ion-exchange chromatography; 3-propanediols; 2-Diaryl-1; 2; X-ray crystallography;

    Abstract : Lignin model compounds representative of structural elements in lignin of the b-1, b-5, b-O-4, cinnamaldehyde and cinnamyl alcohol types were synthesized. erythro-Forms of b-1 models of the 1,2-diaryl-1,3-propanediol type were prepared by BF3-catalyzed rearrangement of chalcone epoxides and subsequent reduction of the rearrangement products with NaBH4.

  6. 4. Passenger assessments of quality in local public transport- measurement, variability and planning implications

    Author : Helena Sjöstrand; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

    Abstract : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. READ MORE

  7. 5. Synergistic Strategies in Multi-Robot Systems: Exploring Task Assignment and Multi-Agent Pathfinding

    Author : Yifan Bai; George Nikolakopoulos; Tomi Westerlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous robots; Multi-robot systems; Task assignment; Multi-agent path-finding; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Abstract : Robots are increasingly utilized in industry for their capability to perform repetitive,complex tasks in environments unsuitable for humans. This surge in robotic applicationshas spurred research into Multi-Robot Systems (MRS), which aim to tackle complex tasksrequiring collaboration among multiple robots, thereby boosting overall efficiency.
