Self-­Supervised Learning for Visual Obstacle Avoidance

van Dijk, Tom (author)

With a growing number of drones, the risk of collision with other air traffic or fixed obstacles increases. New safety measures are required to keep the operation of Unmanned Aerial Vehicles (UAVs) safe. One of these measures is the use of a Collision Avoidance System (CAS), a system that helps the drone autonomously detect and avoid obstacles....

Onderzoek naar de generieke productiviteitsontwikkeling in de reguleringsmethode van TenneT TSO BV

Blank, J.L.T. (author), Bos, J.W.B. (author), Koot, P.M. (author), Balk, B.M. (author)

Dit rapport analyseert de reguleringsmethode van TenneT door de NMa en beantwoordt drie door de NMa voorgelegde vragen. De eerste vraag betreft de mate waarin de huidige reguleringsmethode leidt tot de juiste prikkels voor TenneT om de doelmatigheid van de bedrijfsvoering te bevorderen. De tweede vraag betreft de mate waarin de huidige...

Multi-agent model predictive control for transportation networks: Serial versus parallel schemes

Negenborn, R.R. (author), De Schutter, B. (author), Hellendoorn, J. (author)

We consider the control of large-scale transportation networks, like road traffic networks, power distribution networks, water distribution networks, etc. Control of these networks is often not possible from a single point by a single intelligent control agent; instead control has to be performed using multiple intelligent agents. We consider...

Final report on generic prediction method of wave overtopping

Van Gent, M.R.A. (author), Pozueta, B. (author), Van den Boogaard, H.F.P. (author), Medina, J.R. (author)

Within the framework of the European project CLASH phenomena related to wave overtopping are studied. In this report a method to predict wave overtopping at a wide range of coastal structure types is given. The method is based on Neural Network modelling of the mean wave overtopping discharge. The method can be applied for coastal structures...

Effect of obliqueness, short-crested waves and directional spreading, report on additional tests

Lykke Andersen, T. (author), Burcharth, H.F. (author)

Based on a database of laboratory data on wave overtopping (around 10,000 tests) a neural network technique is used for producing a generic prediction method. In the first database (around 7,000 tests) the following white spots were detected where additional tests could improve the generic prediction method. This report deals with the laboratory...

Data mining, knowledge discovery and data-driven modelling

Solomatine, D.P. (author), Velickov, S. (author), Bhattacharya, B. (author), Van der Wal, B. (author)

The project was aimed at exploring the possibilities of a new paradigm in modelling - data-driven modelling, often referred as "data mining". Several application areas were considered: sedimentation problems in the Port of Rotterdam, automatic soil classification on the basis of cone penetration tests, prediction of water levels in the ocean,...
