This thesis applies data mining in commercial settings in the telecommunications industry.

The elicitation of mentor teachers' practical knowledge by prospective teachers

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

Modern computer-aided simulation tools used by various industries produce gigabytes of data. But currently, they take days and even up to weeks of computation effort. To make the best use of all these data, the DAMIOSO project focuses on developing algorithms and tools for managing, mining, and optimizing…

PUMA aims at composing a geological map of the urban mine of Amsterdam for a selection of metals. Where are main deposits of copper, iron and aluminium located, when will they become available for secondary production, in what state and shape are they?

The change from a closed institution to an open living environment for patients with late stages of dementia will give the patients more freedom in their day-to-day life. The effect of this change on the patients’ mobility, activity and interaction with others will be assessed with sensor technology…

On dinsdag 26 juni 2018, Linlin Sun defended her doctoral thesis ‘International Environmental Obligations and Liabilities in Deep Seabed Mining’. The doctoral research was supervised by Prof. dr. N.J. Schrijver en Prof. dr. E.C.P.D.C. De Brabandere.

Mining time series is a machine learning subfield that focuses on a particular data structure, where variables are measured over (short or long) periods of time.

This project develops a scientific method to extract clinically relevant new information from patient forum websites that discuss patient experiences concerning e.g. medication, nutrition, co-morbidities, genetic factors etc.

Abdolreza Alamdar Baghini defended his thesis on 5 December 2019.

Open Educational Resources (OER) have the potential to change teaching in Higher Education, but adoption is low despite the growing amount of resources available. The current project aims to investigate if and how teacher communities can foster adoption of OER in curricula.

Policy Note Insecurity in Burkina Faso – beyond conflict minerals: The complex links between artisanal gold mining and violence

Using positional data to determine which tactics lead to a successful attack? Rens Meerhoff, researcher at the Sports Data Center of the Leiden Institute of Advanced Computer Science (LIACS), has been using data-mining to analyse football tactics for several years. In Friesch Dagblad he explains the…

Raw materials should no longer be excavated from mines, but reused from sources that are already present, such as unused underground electricity cables and discarded ships. At least, that is necessary for a circular economy. A new report explores where these resources are located and how we can use…

A plant that takes metal from the ground all by itself: a natural way to mine or to clean the soil. PhD student Roderick Bouman (Hortus Botanicus Leiden) described a new plant species from Sabah, Borneo, which can be used to extract nickel. In an open access article in Botanical studies, he and the…

On 21 January, the Institute of Environmental Sciences (CML) has released two reports on circular economy and urban mining in the Netherlands. In them, together with Statistics Netherlands, they take stock of part of the Dutch ‘urban mine’: how much raw material can we reuse from the electricity grid,…

Tanja Masson-Zwaan, an assistant professor at the Institute of Air and Space Law, spoke on Friday 14 April about space mining on BBC Radio.

The SAPPAO project aims to optimise the accuracy and reliability of predicting scheduled flight times. The full name of the project is 'A Systems Approach towards Data Mining and Prediction in Airlines Operations'.

In an (Dutch) interview with the regional Leiden newspaper “Leidsch Dagblad”, Ruben Huele and Ester van der Voet talk about the recently started project PUMA (Prospecting the Urban Mines of Amsterdam).

On Tuesday 26 June Linlin Sun will defend her dissertation entitled ‘International Environmental Obligations and Liabilities in Deep Seabed Mining’. The dissertation has been written under the supervision of prof. dr. N.J. Schrijver and prof. dr. E.C.P.D.C. De Brabandere.

North Korean detention camps are no different from Nazi prison camps. But as long as the country remains economically isolated, international criticism will be ineffective, writes North Korea expert Remco Breuker in the opinion section of Dutch newspaper NRC on 21 February. Breuker advocates using the…

Recycling of post consumer plastic waste is problematic in that the environmental benefits are questionable and the costs are significant. It would be better to separately collect the most useful parts through the expansion of the deposit system.

In this thesis, several aspects of software debugging from automated crash reproduction to bug report analysis and use of contracts have been studied.

Over the last 5-6 years Burkina Faso has become seriously implicated in the rapid and dramatic changes in the geopolitical situation in the Sahel. The country, once reputed for its stability and safety, has come under the spotlight for the number of violent attacks and of internally displaced people.…

In this work, we attempt to answer the question:

An international and multi-disciplinary research consortium spent two days at Leiden University for the launch of their ‘GOLD MATTERS’ project, funded jointly by NORFACE and Belmont Forum. The project 'Sustainability Transformations in Artisanal and Small-scale Gold Mining: A Multi-Actor and Trans-Regional…
