Study Group Mathematics with Industry 2015
SWI 2015 was held 26–30 January at the Mathematical Institute, Utrecht University. Problems were submitted by Philips, SKF, MobiDot, KNMI (Royal Netherlands Meteorological Institute), NMGroup and the Netherlands Cancer Institute.
Organisation committee SWI 2015:
Ross Kang (Nijmegen),
Tobias Müller — chair,
The workshop follows a traditional format. Companies present a selection of problems on the Monday. The participants devote the entire week to solving these problems in smaller groups. Each group presents their work on the Friday. Wednesday evening is the conference dinner. On Thursday night there is pizza to fuel preparation of the final presentations.
It is opened by Marjan Oudeman, Chair of CvB UU, on Monday morning at Boothzaal, UBU (Heidelberglaan 3). Working rooms are situated in Hans Freudenthalgebouw (Budapestlaan 6). Closing presentations take place on Friday, back in the Boothzaal.
For more information, consult the final programme (pdf).
For quick travel information, see the UBU travel advice; to help in orientation, here is the UBU building, as viewed from the Heidelberglaan bus stop. If needed, a parking pass may be arranged beforehand by contacting firstname.lastname@example.org. Many participants stay at the Mitland hotel, which is close to stop Oorsprongpark on bus line 28. Note that eduroam is available all over the campus, but make sure to set this up before leaving your home institution.

The event attracted coverage from RTV Utrecht and Radio EenVandaag:
- “Utrecht is Wakker” (around 39:25).
- “Wiskundeproblemen oplossen bij bedrijven“
- “Wiskunde met de Industrie – tussenstand“
- “Wiskundeproblemen oplossen bij bedrijven: de deadline“
There is an article (in Dutch) in Technische Weekblad.
A popular proceedings has been prepared and is available here (in Dutch).

For radiation oncology we treat patients with head and neck tumours over the course of 6-7 weeks. This treatment is usually based on one CT scan prior to treatment. We use that as an input for dose calculations in the patient based on a collapsed cone superposition algorithm. To optimise the dose distribution we useView problem details
Building new infrastructure such as transmission lines, roads, rail, etc. is always a source of controversy. High voltage transmission lines blight the landscape they are constructed on, bringing social, environmental and economic detriment to the areas they run through, equally they form the fabric of modern infrastructure enabling efficient transfer of power across the country.View problem details
The Problem The sampling density function in Compressed Sensing can best be optimized once the -space density is known for the object under investigation. This is characterized by an MRI scan (fast pre-acquired data set), from which the -space extent is estimated by a Fourier Transform. In addition, the data is acquired with multiple, spatially-localized,View problem details
The goal is to model and optimize bearing life testing time under constraints. The constraints are from various kinds: Number of available test machines (each machine has 2 test positions): Number of life tests to be run: Statistical distribution assumed for individual bearing life: Weibull (,) Assessed precision: expected maximum ratio between confidence bounds onView problem details
Systems as diverse as clocks, singing crickets, cardiac pacemakers, firing neurons and applauding audiences exhibit a tendency to operate in synchrony. The phenomenon that dynamical systems synchronise their behaviour by some form of information exchange is known as synchronisation. In recent years, the concept of synchronisation is being applied in weather and climate research. ObservedView problem details
Our SWI problem formulation focusses on advancing the quality of our data derivation. Mobidot infers the route, role,objective and mode of transportation from Smartphone data. Smartphones possess a variety of sensors, including GPS, mobile telephone (4G) and wi-fi signals, accelerometer-based mode, etc. that can be used to determine the motion and position of the user,View problem details
