The localisation of freight wagons on marshalling yards: Using multiple GPS measurements of stationary freight wagons to determine their location on a marshalling yard

Freight is moved by trucks on the road more and more, which is a worrying thing, especially for the environment. A very good alternative to transportation by trucks is transportation by trains. The Dutch government aims to increase the transportation of goods by train from 13% of all transportation to 20% of all transportation, but in reality,...

Exploring a pure landmark-based approach for indoor localisation

Humans interact more and more with their environment through technology, recent decades have seen a huge increase in the need for and availability of Location-Based Services (LBS). Recently landmarks have gotten a renewed interest in the field of LBS , although already a quite old phenomenon. In both the outdoor and indoor environment they are...

Analysing TDoA Localisation in LoRa Networks

The IoT contains billions of interconnected devices and is only growing larger by the day. These devices often need to operate for years while keeping mobile objects, such as animals or vehicles, connected to a larger system. Therefore they will be battery-powered, energy efficient and, their position will be tracked. Therefore, connecting these...

Virtual Referee: A system to identify off- sides in Football

The off-side rule is the most complicated rule in soccer. Today, off-sides are determined with the help of referees running on the sides of the field or with the help of cameras. However, for lower league games the installation of a camera based system is very expensive. <br/><br/>This work proposes a sensor based system that can be worn by...

Influence of Interface and Type of Strain Hardening Cementitious Composite (SHCC) on Crack Control in SHCC-Concrete Hybrid Beams

A combination of conventional concrete members with innovative material such as Strain Hardening Cementitious Composite (SHCC) in the tensile zone, can exhibit better crack-width control. This is attributed to the bridging effect by the Polyvinyl Alcohol (PVA) fibers used in SHCC in combination with the special material composition containing...

LoRa Localisation in Cities with Neural Networks

Billions of wireless devices are interconnected to provide services to many<br/>aspects of life and form The Internet of Things. These devices which are<br/>often battery-powered and energy efficient can benefit greatly from an ac-<br/>curate localisation service that does not consume extra energy. Several loc-<br/>alisation methods have been...

Verification of an XFEM Based Slope Stability Analysis Method

There are multiple numerical methods for analysing the stability of slopes. Commonly used methods for assessing the slope stability are the slip surface method, strength reduction methods or methods based on load increments. What those methods have in common is that the stability of a slope is assessed by a factor of safety or critical stability...
