This cluster consists of the following projects:

Remote detection of drugs and explosives

The focus of this project will be in the development of highly sensitive, selective, stable and robust sensors that are capable of detecting very small quantities of the target substances in the presence of other potentially interfering substances in differing weather conditions. Sensors capable of detecting hazardous substances can help the police to uncover criminal activity at an early stage, thereby reducing or even preventing its negative consequences. In light of this, sensor research into substances that may or may not be hazardous is one of the key areas being looked at by the Advanced Forensic Technology (AFT) research group. You will help us by contributing to this research by developing a demonstrator that can detect hazardous substances.

Field Engineer 3.0 – digital soil investigation for health, forensic and environment

Urban areas face large changes. A sustainable energy transition, adapting to climate change and a huge task in building new houses. Scarcity of space and increasing pressure on the living environment makes the use of the subsurface more and more important. Energy from the soil, waterstorage, cables and pipelines – the subsurface is increasingly important. Furthermore – construction of buildings and infrastructure is more and more done in the subsurce. Civil and archeological surveys of the soil are crucial. Research and fieldwork on urban soil is a crucial cornerstone for this. Knowing the structure, groundwater tables and chemical composition makes sustainable urban planning and construction possible. Due to growing scarcity of space, time and skilled personnel we examine  the possibillities of more and more autonomous process of fieldwork: taking samples and analyse them. We call that the soil field engeneer 3.0. In this assignment, a student group will explore the possibilities of (semi-) autonomous sample taking. Antea Group consultancy & engineering and the research groups Mechatronica and Soil and Underground of Saxion work together on this research.  Central in this assignment are the following research questions: 1) what are the main characteristics of the current way of sample taking? What are the best practices and expierences in civil, environmental, archeologic and forensic field work on soil? 2) Which knowledge and skills do the current field workers have? 3) What are the requirements for a digital field engeneer following from that? 4) What is already done in autonomous field work on soil issues? What issues are still to be developed, such as automatization, lab on a chip-technologies, autonomous measurements, etc. 5) Which techniques are available, and what are the pros and cons of them? Autonomous and semi-autonomous? 6) How can a businesscase on the use of these techniques look like? 7) What steps are necessary to develop a first prototype? Deliverables: a report with the results of the research, a factsheets on existing technologies that (possible) can provide the desired functions, a business case, technical requirements and implementationplan for developing a prototype.

Sensoring for climate change

Climate change is an urgent and political topic. One of the main aspects of climate change is dealing with droughts. Longer periods with less rain induce lower groundwatertables. Our region of east-Netherlands suffers from this. These lowering groundwatertables lead to drying out of agricultural crops and natural areas, land subsidence and problems with foundations of houses and infrastructure. Antea Group consultancy & engineering and the research groups BioNano and Soil and Underground of Saxion work together on research of these problems with groundwater and droughts. In this assignment they are looking for students that want to work on the development of smart sensoring for these issues. Central in this assignment are the following research questions: what ways of measuring are there, how can sensors help in measuring groundwatertables, their development and their impact on soil subsidence and foundations of buildings, what is de potential size of the problem and the potential value of sensoring for that, which sensors are available, and what are the pros and cons of them, how can a businesscase on the use of these sensors look like, when is a ‘senor-package’ attractive for potential customers, develop such a businesscase: what do we have to do if we want to develop a sensor-package, what are the alternatives for such a business case, how can these help into drought issues in the east of the Netherlands? We research these question by using two cases: 1) concerning groundwater draughts in an urban area, 2) concerning groundwater and foundation problems in one or several buildings. Deliverables: a report with the results of the research, factsheets on existing sensors that (possible) can provide the desired functions, a business case and implementationplan for developing adequate sensors – sensorpackage, a design (VO) for a monitoringplan for both cases.

Sensoring for health detection for asbestos in soil

Health issues are important issues in modern society. In ths, dealing with asbest plays an important role. During the 20eth century, asbestos was used in many applications, such as in rooftops of houses, barns and industry, roals construction and sewers. Even though the use of asbestos has already been forbidden for decades, it is still abundant in these roofs and construction works. Moreover, difuse spread of asbestos particles via rainfall, for example on land near roads, poses a big threat to human health. Political discussions revolve around how to get rid of these difuse particles and how to pay for this. An important issue in dealing with asbestos is the detection of it. If the presence of asbestos is suspected – for example whilst renovating a house or constructing a new road – extensive laboraty research is obligatory. This causes  substantial delay and costs. Antea Group consultancy & engineering and the research group BioNano and Soil and Underground of Saxion work together on research of these problems with asbestos. In this assignment they are looking for students that want to work on the development of smart sensoring for these issues. Central in this assignment are the following research questions: how can sensors measure asbestos in soil and debris, what is de potential size of the problem and the potential value of sensoring for that, which sensors are available, and what are the pros and cons of them, what are the main issues in implementation of sensors for this issue, how can a businesscase on the use of these sensors look like, develop such a businesscase. Deliverables: a report with the results of the research, factsheets on existing sensors that (possible) can provide the desired functions, a business case and implementationplan for developing adequate sensors – sensorpackage.

Multi-temporal remote sensing

The world around us is changing as we speak. Various challenges for the near future have been addressed by the Dutch government. These challenges are summarized in four missions on the topics of Health, Security, Food Production and Climate. One of the addressed key technologies in the last three missions is remote sensing. Remote sensing is the acquisition of information about the surface of the earth without making physical contact. A distinction is made between active and passive techniques. In active techniques a signal is emitted by source and its reflection is detected by a sensor. In passive techniques reflection of natural radiation such as the reflection of sunlight is detected by a sensor. The Soil and Subsurface Research Group intends to establish a Centre of Expertise for Remote Sensing in the near future. In this TripleS-project you will work on three exemplary projects in the field of civil engineering, archaeology and water safety which relate to subjects like climatic change, heat stress, soil subsidence and air quality. The projects will be carried out for Omgevingsdienst Midden-Holland (ODMH). The focus in these sub-projects is the use of multi-temporal imagery at different geographical scales. Data from various sources will be provided by this organization. Furthermore you will use downloadable open data from platforms like AHN.nl and sattelietdata.nl. For each sub-project it will be possible to acquire data with a sensor at a test-location. Therefore a small amount of fieldwork will be part of the project. The exact content of the project and product will be defined with ODMH and the Soil and Subsurface Research Group. The choice for a specific sensor and test location has to be well substantiated by the project team and discussed thoroughly with the professionals of ODMH. One of the challenges at the end of the project is to think up a smart solution for presenting the acquired data in the online webserver of ODMH. The project requires an intrinsic interest in working with GIS (Geographic Information System) but skills in working with GIS are not mandatory. We expect students to develop these skills during the project. Although upfront skills in working with GIS-software like QGIS or ArcGIS are in this project an advantage.
