Mededeling van het Bestuur

Be?indiging Elektronische Mededelingen van het KWG per 1-1-2018

Per 1 januari 2018 zullen de Elektronische Mededelingen van het KWG worden stopgezet. De reden hiervoor is dat het lastig is om per e-mail agenda en nieuwsberichten te verspreiden zonder klachten te krijgen over leesbaarheid of aantal klikken die nodig zijn om de Mededelingen op het scherm zichtbaar te maken. De huidige opzet is verouderd en kost de opstellers veel tijd. Verder verschraalt het aanbod en er bestaat enige twijfel of alle onderdelen van de Mededelingen gelezen worden.

Voor de agenda is de Wiskunde Persdienst beschikbaar en nieuwsberichten staan o.a. op de WPD en/of de KWG website.

De Mededelingen van het Bestuur die regelmatig aan het begin van de Elektronische Mededelingen worden opgenomen blijven bestaan maar in een andere vorm: ze worden vanaf 1-1-2018 als tekstbericht aan de KWG-leden, van wie we een correct e-mail adres hebben, toegezonden met als Subject: ?Mededeling(en) van het KWG-bestuur?. Dit zijn bv. aankondigingen van het NMC, van Algemene Ledenvergaderingen, van Statutenwijzigingen en van andere voor het Genootschap belangrijke zaken.

Mocht u toch prijs stellen op regelmatige toezending van agenda en nieuwsberichten dan verzoeken we u mee te denken over een nieuwe opzet.

Voor evt. commentaar/suggesties, mail naar wiskgenoot

Call for submissions for the KWG PhD prize for the best presentation of PhD research in mathematics

Every year, the Dutch Royal Mathematical Society (KWG) invites several PhD candidates to present their research at the Dutch Mathematical Congress (NMC). A jury of mathematicians from various fields chooses a winner who receives, besides the prestige attached to winning, a floating trophy and a monetary reward of 1000 euro.

This year the PhD prize competition is open to PhD candidates in mathematics from all universities in the Netherlands, and the 2018 KWG Dutch Mathe?mati?cal Congress will be held on April 3rd and 4th at the Koningshof in Veldhoven (near Eindhoven). The jury will be chaired by Prof. dr. Bas Edixhoven (UL).
The prize money is made available by Bronstee.com.

In order to enter the competition please send an extended abstract (one page approximately, maximum of two pages) and short CV (maximum one page) to the following email address
kwg.phd.prize@gmail.com. Please also ask your daily supervisor to send a concise letter of recommendation to the same address.

The deadline for proposals is Sunday, January 28th 2018.

Professor Samir Siksek
Mathematics Institute
University of Warwick

INRIA (Paris, France), and Philips (Eindhoven)

PhD position, jointly in INRIA (Paris) and Philips (Eindhoven). The division of time is 50-50 between Paris and Eindhoven, while the precise schedule is still to be determined.

The supervisors will be Jean-David Benamou in Paris, one of the leaders in the area of Optimal Transport, and Wilbert IJzerman in Eindhoven, a group leader at Philips and part-time professor at TU Eindhoven. Together with Jan ten Thije Boonkkamp (maths, TUe) and others in other departments Wilbert is building a group of people in Eindhoven working on mathematical problems that arise in lighting.

Scientific context
FreeForm Optics [FFO] is the branch of Optics concerned with the design of non-conventional asymmetric refractive and reflective optical elements [OE] or systems of such elements. This research is important to improve the energy efficiency of lighting devices and reduce light pollution (for example of street lighting). A classic application of FFO (amongst many) is the irradiance tailoring problem : design an optical system transferring a given light source emittance (e.g a car headlight bulb) to a prescribed irregular target irradiance (e.g. the angular far field distribution of projected light). The FFO design at the industrial level has remained so far largely heuristic.
On the academic side, two classes (collimated or point source illuminance) of idealized tailoring irradiance problems can be exactly modelled and solved using Optimal Transport [OT] theory. OT defines a unique map or a coupling between prescribed distributions representing given illuminance and irradiance. This map can then be used to construct the OE shape. Recent advances in OT numerical solvers allow to tackle systems described by millions of degrees of freedom. This offers a sound mathematical and numerical background to FFO.

1) OT modeling cannot be directly used for systems of OE involving multiple reflectors/lenses. 2)
The collimated or point source illuminance hypothesis is not compatible with the use of LED light source technology and the current miniaturization trend. The size of the light source is too large compared to be considered as a far field point source for the reflector part of the OE. The OT theory and solvers again cannot directly be used.


-    Master degree (or equivalent) in Applied Mathematics or Optical

-    Engineering Excellent Programming skills.

-    Optional : Familiarity with convex analysis, calculus of variation and nonlinear optimization techniques.

-    Strong interest in interdisciplinary scientific work.

-    Ability to work independently and as part of a team.

-    Strong motivation to pursue a PhD degree.

Applications should be sent to: Jean-David.Benamou, Wilbert.Ijzerman

Eligibility: The candidate recruited in the ROMSOC project must be in the first four years from the date when the candidate obtained the degree entitling him or her to embark on a doctorate (e.g. master degree). No doctoral degree has been awarded during these four years. The candidate must not have resided or carried out her/his main activity (work, studies, etc.) in France for more than 12 months in the 3 years immediately prior to the recruitment date. Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not taken into account. The candidate must work exclu?sively for the project during the employment contract. The candidate must fulfill the conditions to be admitted in the PhD programme indicated in the job vacancy. Tuition fees will be covered by the fellowship. These condi?tions must be fulfilled at the starting date of the contract.
