1. 6. Offline Task Scheduling in a Three-layer Edge-Cloud Architecture

   Författare :Ayeh Mahjoubi; Karl-Johan Grinnemo; Arunselvan Ramaswamy; Alessandro Papadopoulos; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; task offloading; task scheduling; edge computing; internet of things; optimization techniques; heuristics; meta-heuristics; Computer Science; Datavetenskap;

   Sammanfattning : Internet of Things (IoT) devices are increasingly being used everywhere, from the factory to the hospital to the house to the car. IoT devices typically have limited processing resources, so they must rely on cloud servers to accomplish their tasks. Thus, many obstacles need to be overcome while offloading tasks to the cloud.

3. 7. Optimisation models for train timetabling and marshalling yard planning

   Författare :Sara Gestrelius; Anders Peterson; Martin Aronsson; Pieter Vansteenwegen; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Railways provide high capacity, safe and energy efficient transportation of goods and passengers. However, railway transportation also suffers from intrinsic restrictions and the effectiveness and efficiency of the transportation depend on the railway actors’ ability to solve a set of hard and interconnected planning problems.

4. 8. Optimization Approaches for Design of Congestion Pricing Schemes

   Författare :Joakim Ekström; Jan Lundgren; Richard Connors; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent years, there has been a growing interest in congestion pricing as a tool for solving traffic congestion problems in urban areas. However, the transportation system is complex and to design a congestion pricing scheme, i.e. to decide where and how much to charge the road users, is not trivial. LÄS MER

5. 9. Automated Support for the Architecting of Distributed Embedded Systems : Methods and Analysis for Industrial Adoption

   Författare :Xinhai Zhang; Martin Törngren; Marco Di Natale; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion; Computer Science; Datalogi;

   Sammanfattning : The architecture design complexity of modern embedded systems, such as in the automotive domain, is growing due to the rapidly evolved functionalities, the increasing amount of interactions between functions and computation nodes, and the stringent extra-functional requirements. Architecture design is crucial since it affects nontrivial system properties such as safety, cost, performance of functionalities and also the development time. LÄS MER

7. 10. Optimization-Based Methods for Revising Train Timetables with Focus on Robustness

   Författare :Fahimeh Khoshniyat; Jan Lundgren; Johanna Törnquist Krasemann; Steven Harrod; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : With increase in the use of railway transport, ensuring robustness in railway timetables has never been this important. In a dense railway timetable even a small disturbance can propagate easily and affect trains' arrival and departure times. In a robust timetable small delays are absorbed and knock-on effects are prevented effectively. LÄS MER
