1. 16. Railway traffic disturbance management

   Författare :Johanna Törnquist; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Railway traffic; Transportation; Re-scheduling; Disturbance management; Decision support systems;

   Sammanfattning : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. LÄS MER

3. 17. Characterization and Classification of Internet Backbone Traffic

   Författare :Wolfgang John; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Characterization; Measurement; Backbone; Internet; Classification; Traffic; Passive;

   Sammanfattning : We contribute to an improved understanding of Internet traffic characteristics by measuring and analyzing modern Internet backbone data. We start the thesis with an overview of several important considerations for passive Internet traffic collection on large-scale network links. LÄS MER

5. 19. Vessel Traffic Service (VTS): a maritime information service or traffic control system?

   Författare :Gesa Praetorius; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive Systems Engineering; Performance Variability; Resilience Engineering; Traffic Management; Functional Resonance Analysis Method FRAM ; Vessel Traffic Service;

   Sammanfattning : Vessel Traffic Service (VTS) is a shore-side maritime assistance service that supports bridge teams in their safe navigation of port approaches and other areas that present navigational difficulties. The VTS is implemented in national waters and provides vessels with information through transmissions and broadcasts on Very High Frequency (VHF) radio. LÄS MER
