ELLIS Delft Talk by Javier Alonso-Mora

ELLIS Delft Talk by Javier Alonso-Mora 12 April 2022 16:00 (NOTE: the meeting moved from 5th -> 12th) This will be a hybrid meeting This meeting is open for all interested researchers. Motion Planning among Decision-Making Agents: Trajectory Optimization with Learned Cost Functions Abstract We move towards an era of smart cities, where autonomous vehicles will provide on-demand transportation while making our streets safer and mobile robots will coexist with humans. The motion plan of mobile robots and autonomous vehicles must, therefore, account for the interaction with other agents and consider that they are, as well, decision-making entities. For example, when humans drive a car, they are fully aware of their environment and how other drivers and pedestrians may react to their future actions. Towards this objective I will discuss several methods for motion planning and multi-robot coordination that leverage constrained optimization and reinforcement learning to achieve interactive behaviors with safety guarantees. Namely: using inverse reinforcement learning and social value estimation to achieve social behaviors; employing a learned policy to guide the motion planner in dense traffic scenarios or for information gathering; achieving social trajectories by learning a cost function from a dataset of human-driven vehicles; and learning to communicate the relevant information for multi-robot coordination. The methods are of broad applicability, including autonomous vehicles and aerial vehicles.

van Duijvenbode, J.R.

Profile TU Delft (2018 – current) Ph.D. candidate in Resource Engineering I obtained a MSc degree in the European Mining Course (EMC) from Delft University of Technology, Aalto University and RWTH Aachen. My master thesis was about: Development and Validation of Short-term Mine Planning Optimization Algorithms for a Sublevel Stoping Operation with Backfilling. Research PhD research into the behavioural Geology – Understanding how differences in geology influence metallurgical performance. The research topic consists of integrating collected information on metallurgical properties, directly or through proxies back into the resource model. The consideration of metallurgical costs is the only way forward to obtain truly optimized mining decisions, accounting for constraints and bottlenecks in the comminution circuit and chemical processing plant. This is important to better characterize metallurgical behavior of the plant feed, which allows for a morel optimal selection of process control settings. The envisioned solution will result in an increased recovery in combination with a lower utilization of energy and chemicals per tonne of processed material (lower environmental footprint). Consequently, overall OPEX will drop making lower grade ore economic while increasing the mineral resources that are available for conversion to ore reserves (lesser need to open up new mines). Moreover, a better characterization of mining blocks reduces the unintended processing of waste due to lower overall classification errors. Copromotor: Dr. M. Soleymani Shishvan Promotor(s): Dr. M.

ELLIS Delft Talk by Guillaume Rongier

ELLIS Delft Talk by Guillaume Rongier Going beyond empirical relationships in geology: The example of total organic carbon 01 February 2022 16:00 Abstract While machine learning has a long history in geology, empirical relationships remain widely used. Through the example of total organic carbon (TOC), this talk will illustrate the close links between empirical relationships and machine learning, and the benefits of turning to machine learning. TOC is a measure of the proportion of organic carbon in rock samples typically gathered from boreholes. It can be used to assess the potential for hydrocarbons, understand rock mechanics, or assess reducing conditions for basin-hosted mineral systems, and is paramount when seeking to understand variations in paleo-environmental conditions. Since gathering and analyzing rock samples is expensive, empirical relationships have been developed to predict TOC from well logs, which are based on more widely available geophysical measurements into boreholes. Those empirical relationships come from geological and petrophysical principles implemented in mathematical models manually fitted to the data. This leads to several limitations, mainly poor generalization, inability to quantify uncertainties, time-consuming and subjective calibration that leads to reproducibility issues. But those empirical relationships can be rewritten as linear regressions, a simple change that solves many of the previous limitations. Turning to more advanced machine learning methods improves predictions by taking into account the non-linearity and variability in the data. Using the expert knowledge behind empirical relationships as input besides well logs improves the predictions as well: this shows that leveraging geological and petrophysical concepts through feature selection and engineering boosts machine learning performances.

Early attempt at colour photography discovered

Delft University of Technology has unearthed six glass slides (1890 – 1910), which represent one of the earliest attempts at colour photography. The slides were found during an inventory conducted by the Programme Tailor-Made Approach to Faculty Collections at the Imaging Physics department of the Faculty of Applied Sciences. To view the images, technician Thim Zuidwijk reconstructed a diffraction chromoscope, revealing vivid depictions of a vase with a floral motif and a still life of a fruit basket alongside a banana and a wrapped citrus fruit.

How storm surge barriers can keep the Netherlands safe and liveable

A safe and liveable delta, who doesn't go for that? Storm surge barriers play a crucial role in this. Yet there are many choices to be made in the short term to keep the storm surge barriers in a good condition, to eventually cope with rising sea levels in the longer term. A new project receives funding from NWO for five years to explore the best routes to a liveable delta. Storm surge barriers, like the Maeslantkering and the Oosterscheldekering are essential for protecting the Netherlands from high water coming in from the sea. How long will these imposing structures remain effective bearing in mind sea level rise, decay of the structures and an altering surrounding area. In the short term, decisions will have to be taken on maintenance, while in the longer term, adaptation or replacement should be considered. Linking storm surge barriers with the delta Within the SSB-Δ (storm surge barrier delta) project, a diverse consortium will investigate under what circumstances storm surge barriers can keep the Netherlands safe and liveable. The consortium consists of the universities of Delft, Utrecht, and Rotterdam; the universities of applied sciences of Rotterdam and Zeeland; knowledge institutes Deltares and TNO, as well as Rijkswaterstaat, water boards and companies. Bram van Prooijen, associate professor at TU Delft, will lead the research: “Decisions on flood defences are important for the entire delta. The link between the hinterland and the flood defences needs to be made properly. During this project, we will have the opportunity to bring different areas of expertise together and strengthen each other.” Long term perspective Therefore, the research is not only about the technical lifespan of the barriers. It will also clarify how the delta is going to change and how society thinks about it, resulting in a guideline to on how and when decisions need to be taken in the short term, with a long term perspective. Van Prooijen cites an example of car maintenance: “Think of replacing the engine block. This is very expensive maintenance, but sometimes necessary to keep the car running safely. But is it worth the investment if you plan to buy a new car next year? Or if you prefer to travel by train? Important choices will have to be made for storm surge barriers. We want to provide a strong basis for that.” Informed decisions The project will reveal the possible pathways to a liveable delta, and how storm surge barriers fit into that. Van Prooijen: “That offers clarity, to make quick and better-informed decisions. Many trials run for a long time, with the outcome of this research we can decide which trials specifically are the best option to proceed with.” Future experts One of the storm surge barriers involved in the research is the Maeslantkering. This barrier is expected to last another fifty years or so. That may seem far away, Van Prooijen reasons, “but we need to train the experts who will decide on this now. Those are probably the PhD students on this project.”

Besides this, some topics and challenges are so complex and multifaceted that they affect various faculties and call for multidisciplinary approaches. At TU Delft, a team of researchers and support staff have joined forces to tackle the issue of improving cybersecurity and detecting cybercrime. How do we keep the internet, and therefore Dutch and European society, safe?

Researchers hand over Position Paper to Tweede Kamer

On behalf of the TU Delft PowerWeb Institute, researchers Kenneth Brunninx and Simon Tindemans are handing over a Position Paper to the Dutch Parliament on 14 November 2024, with a possible solution to the major grid capacity problems that are increasingly cropping up in the Netherlands. The Netherlands is unlikely to meet the 2030 climate targets, and one of the reasons for this is that large industry cannot switch to electricity fast enough, partly because of increasingly frequent problems around grid capacity and grid congestion. In all likelihood, those problems will actually increase this decade before they can decrease, the researchers argue. The solution offered by the TU Delft PowerWeb Institute researchers is the ‘flexible backstop’. With a flexible backstop, the current capacity of the power grid can be used more efficiently without sacrificing safety or reliability. A flexible backstop is a safety mechanism that automatically and quickly reduces the amount of electricity that an electric unit can draw from the grid (an electric charging station or a heat pump) or deliver (a PV installation). It is a small device connected or built into an electrical unit, such as a charging station or heat pump, that ‘communicates’ with the distribution network operator. In case of extreme stress on the network, the network operator sends a signal to the device to limit the amount of power. Germany recently introduced a similar system with electric charging stations. The backstop would be activated only in periods of acute congestion problems and could help prevent the last resort measure, which is cutting off electricity to users. ‘Upgrading the electricity network remains essential, but in practice it will take years. So there is a need for short-term solutions that can be integrated into long-term planning. We, the members of the TU Delft PowerWeb Institute, call on the government, network operators and regulator to explore the flexible backstop as an additional grid security measure,’ they said.
