In Memoriam Willem van Zwet (1934-2020)

Prof. Willem van Zwet from Leiden University was advisor to the Mathematisch Centrum (now called CWI) from 1965-1984, chair of CWI’s Science Committee and Member of the Board. Throughout his career, Van Zwet played a key role in academic mathematical statistics in the Netherlands.

Bart Kamphorst finds best possible scheduling policy for servers in information-scarce settings

Nobody fancies a long wait between requesting some kind of online service and actually receiving that service. Therefore, in many situations, ICT-specialists aim to design their servers in such a way that their customers are served in an efficient manner. Research of CWI PhD-student Bart Kamphorst contributes a number of performance analyses of blind algorithms and moreover identifies a blind algorithm that is in some sense optimal.

More efficient ambulance planning with new mathematical models

In serious life-threatening situations a fast ambulance response is required. Late arrivals can have a serious impact on the well-being of the patients and can also have consequences regarding policy making. In practice, providing a fast ambulance response time is not always possible. PhD candidate Martin van Buuren of CWI has developed mathematical models that can help to realize fast response times.

CWI and ProRail predict railway incidents

Centrum Wiskunde & Informatica and ProRail recently started a research collaboration in the area of the handling of incidents at the Dutch railways. It concerns a public private partnership between CWI and ProRail striking up a four year period. The research is aimed at prevention and handling of a broad spectrum of railway incidents, like disturbance of the railway infrastructure, people walking on the tracks and collisions.

CWI participates in impact study North/Southline

The North/Southline is the largest operation in Amsterdam’s public transport in decades. That is why the municipality of Amsterdam will start an extensive impact study together with knowledge institutions, the transport region Amsterdam and GVB (public transport company Amsterdam). Centrum Wiskunde & Informatica (CWI) will act as one of the main research partners.

Rubicon grants for David de Laat and Alessandro Zocca

CWI researchers David de Laat and Alessandro Zocca both received an NWO Rubicon grant. De Laat will study new techniques to compute optimal packings at MIT for one year, and Zocca will study renewables and uncertainty in future power systems at Caltech for two years. NWO granted these subsidies to 22 young, highly promising research talents to gain international research experience at foreign top institutes.

CWI researcher makes higher turnover in hotel bookings possible

With a new mathematical method, hotels can receive on average 5% more turnover in the long term when taking online reviews into account. Dirk Sierag, PhD student of CWI, analysed with historical data the behaviour of consumers booking rooms. Based on the results he designed mathematical models that can support hotels in determining optimal prices of hotel rooms. The research results can also be applied on movies, concerts, sporting events and, for example, Uber taxi rides.

NWO Complexity grant for Stochastics researchers

A consortium led by CWI researcher Rob van der Mei (Stochastics) has been awarded a grant within the Complexity in Transport & Logistics programme. Elenna Dugundji of CWI is one of the co-applicants an project manager of the research project. In total 15 proposals were submitted, of which 7 were granted. The available budget for this programme is a maximum of € 3.5 million and is provided by the NWO divisions of Social Sciences (MaGW) and Physical Sciences (EW) and the NWO governing board.
