1. Applying Data Analytics to Freight Train Delays in Shunting Yards
Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

2. Low Power Wireless Technologies for IIoT : Analysis and enhancement of communication delay, reliability and scalability
Sammanfattning : In recent years, the implementation of wireless communication systems in industrial environments has significantly increased. As a result, new applications such as Industrial Internet-of-Things (IIoT) have arisen, reshaping the future of industrial automation. LÄS MER
3. Simulation of rail traffic : Methods for timetable construction,delay modeling and infrastructure evaluation
Sammanfattning : This thesis covers applications and proposes methods for using simulation in a more effectiveway and also in a wider context than normally used. One of the proposed methods deals withdelay modeling that can be used in a calibration process. LÄS MER
4. Measurements and Models of One-Way Transit Time in IP Routers
Sammanfattning : The main goals of this thesis are towards an understanding of the delay process in best-effort Internet for both non-congested and congested networks. A novel measurement system is reported for delay measurements in IP routers, which follows specifications of the IETF RFC 2679. LÄS MER
5. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints
Sammanfattning : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. LÄS MER
