Studying allocation under close to natural conditions requires non-invasive methods, which are now becoming available for measuring plants on a par with those developed for humans. By combining magnetic resonance imaging (MRI) and positron emission tomography (PET), we investigated three contrasting root/shoot systems growing in sand or soil, with respect to their structures, transport routes and the translocation dynamics of recently fixed photoassimilates labelled with the short-lived radioactive carbon isotope 11C. Storage organs of sugar beet (Beta vulgaris) and radish plants (Raphanus sativus) were assessed using MRI, providing images of the internal structures of the organs with high spatial resolution, and while species-specific transport sectoralities, properties of assimilate allocation and unloading characteristics were measured using PET. Growth and carbon allocation within complex root systems were monitored in maize plants (Zea mays), and the results may be used to identify factors affecting root growth in natural substrates or in competition with roots of other plants. MRI-PET co-registration opens the door for non-invasive analysis of plant structures and transport processes that may change in response to genomic, developmental or environmental challenges. It is our aim to make the methods applicable for quantitative analyses of plant traits in phenotyping as well as in understanding the dynamics of key processes that are essential to plant performance.}, language = {en} } @article{WedrowskiBruyndonckxTavernieretal.2009, author = {Wedrowski, M. and Bruyndonckx, P. and Tavernier, S. and Zhi, L. and Dang, J. and Mendes, P.

This paper presents results on the robustness of the spatial resolution as a function of the random fraction in the data, temperature and HV fluctuations.

Time-to-Digital-Converters (TDC) replace the conventional ADCs and multiple TDCs can be realized easily in one PLD chip (Programmable Logic Device). The output of a PWM stage is only one digital signal per channel which is well suited for transport so that further processing can be performed apart from the detector. This is particularly interesting for large systems with high channel density (e.g. high resolution scanners). In this work we present a circuit with a linear transfer function that requires a minimum of components by performing the PWM already in the preamp stage. This allows a very compact and also cost-efficient implementation of the front-end electronics.}, language = {en} } @incollection{BoonzaaijerHelmig2009, author = {Boonzaaijer, Karel and Helmig, Ilka}, title = {2D Room : cardboard installation}, series = {Papercraft [1] : design and art with paper}, booktitle = {Papercraft [1] : design and art with paper}, publisher = {Gestalten Verlag}, address = {Berlin}, isbn = {978-3-89955-251-5}, pages = {206}, year = {2009}, subject = {Papierkunst}, language = {en} } @incollection{HelmigBoonzaaijer2009, author = {Helmig, Ilka and Boonzaaijer, Karel}, title = {Growing 48 hours : design experiment in an aircraft hangar ...}, series = {Papercraft [1] : design and art with paper}, booktitle = {Papercraft [1] : design and art with paper}, publisher = {Gestalten Verlag}, address = {Berlin}, isbn = {978-3-89955-251-5}, pages = {224}, year = {2009}, subject = {Papierkunst}, language = {en} } @incollection{ReimerWellmerBraunetal.2009, author = {Reimer, Lars and Wellmer, Georg and Braun, Carsten and Ballmann, Josef}, title = {Computational methods for aero-structural analysis and optimisation of aircrafts based on reduced-order structural models}, series = {MEGADESIGN and MegaOpt - German initiatives for aerodynamic simulation and optimization in aircraft design.
