This work describes the design, implementation and validation of an autonomous gas leakage inspection robot. Navigation with centimeter level accuracy is achieved using RTK GNSS integrated using the ROS 2 and Nav2 frameworks. The proposed solution has been validated successfully in terms of navigation …

Within our research on robotic gas detection, we have focused on making a prototype based on Boston Dynamics SPOT, because it takes a lot of difficulties out of prototyping. For instance, it has its own obstacle avoidance algorithm, good drivers are available for ROS2, and SPOT is meant for outdoor …

We present an industry use case in which we discuss the practical use of a formal list of definitions. The list of definitions will be used as a basis for a knowledge graph that will serve knowledge panels when interacting with information in the company and that will help improve question answering …

In this abstract we describe a computational approach for detecting discursive patterns in social media. Newsrooms of municipalities and public organizations such as the police follow public debate on social media to be aware of and prepare for local and global issues and rumors. The onset of these issues …

Deze bachelor scriptie is geschreven voor het afstudeeronderzoek dat deel uit maakt van de opleiding archeologie aan Hogeschool Saxion te Deventer. De auteur van deze scriptie is Hugo Pothof. Het doel van dit onderzoek was het ontwikkelen van een nieuwe methode voor het herkennen van afwijkende graven. …

In dit onderzoek is gekeken naar voorbeelden uit de literatuur vanuit verschillende gezondheidsdisciplines. Verschillende studies pasten machine learning (vaak deep learning) toe voor de vroegdetectie van ziekten op basis van beschikbare data uit het elektronisch patiëntendossier (EPD). Het bleek dat …

In recent years, drones have increasingly supported First Responders (FRs) in monitoring incidents and providing additional information. However, analysing drone footage is time-intensive and cognitively demanding. In this research, we investigate the use of AI models for the detection of humans in drone …

In this research there was looked at the connection between the Zeta potential and the pressure sensitivity of a chloroprene dispersion in order to gain insight in dispersion stability. This was done by varying the pH and ionic strength of the chloroprene dispersion. There was also looked at whether …

In mobile robotics, LASER scanners have a wide spectrum of indoor and outdoor applications, both in structured and unstructured environments, due to their accuracy and precision. Most works that use this sensor have their own data representation and their own case-specific modeling strategies, and no …
