To replace these destructive and mechanical penetration methods by non-destructive ultrasonic measurements implies a great advance in order to obtain fast studies about the state of the fruit at the time of harvest, during storage, and in the distribution points. Moreover, there are other advantages since this technique can be fast, non-destructive, fully automated, and performed on-line [1]. Within this context, the objective of this study was to examine the relationship between physico-mechanical characteristics (oil-gland break stress, thickness and dehydration) and ultrasonic characteristics in the ``Salustiana'' orange peel during the complete dehydration process of the orange at ambient conditions. After a description of the measurement system [3], the fruit selection procedure and the measurement protocol, we analyze the results of the change of physico-mechanical and ultrasonic properties in the orange peel and their change with storage time.}}, author = {{Camarena Gandia, Francisco and Hemsel, Tobias and Espinosa, Victor and Twiefel, Jens and Ardid, Miquel and Martinez-Mora, Joan and Gandia, Joan Babtiste}}, booktitle = {{Proceedings of 19th international congress on Acoustics, Madrid}}, title = {{{Non-destructive ultrasonic test of orange dehydration}}}, year = {{2007}}, } @inproceedings{9563, author = {{Genzo, Alexander and Sextro, Walter and Panning, Lars}}, booktitle = {{VDI-Berichte}}, pages = {{147--161}}, publisher = {{VDI Verlag GmbH}}, title = {{{Schwingungsverhalten elastischer Körper mit nichtlinearen Kopplungen in ausgedehnten Reibkontakten}}}, volume = {{2022}}, year = {{2007}}, } @article{9564, abstract = {{Surgical resection of brain tumours is a difficult task.

Assuming a tuned disk assembly, numerical static, free, and then forced vibration analyses of a shrouded turbine blade measured in the spin pit are performed systematically. For the excitation forces of an air jet evaluated from the fairly linear behavior of the experimental blade resonance peaks, the reliability of the proposed approach is validated through the very close agreement of the computed and measured resonant peaks. These resonant peaks demonstrate either a fairly linear behavior or a nonlinear one like the jump effect of blade resonance amplitudes, or elastic impacts between the shrouds. Also, the damping performance for different contact configurations between the shrouds is numerically analyzed. These numerical results indicate that the shrouds generate higher frictional damping for small angles (0{\^a}30deg) between the circumferential direction and the normal vector to the contact surface.}}, author = {{Szwedowicz, J and Visser, R and Sextro, Walter and Masserey, P.

Typically they are visual programming tools that support direct-manipulative assembling of the user interface components. We have developed the tool GuiBuilder which follows a model-driven approach to the development of graphical (multimedia) user interfaces. This allows a meta-design approach where user interface developers as well as prospective users of the system are supported in modelling the desired functionality of the GUI on a high level of abstraction that is easy to understand for all involved stakeholders. The model consists of compositional presentation diagrams to model the structure of the user interface and hierarchical statechart diagrams to model its behaviour. GuiBuilder then supports the transformation of the model to Java, i.e., the generation of a working user interface and the simulation of the modelled behaviour. Interactive sessions with the user interface can be recorded and replayed.}}, author = {{Sauer, Stefan and Engels, Gregor}}, booktitle = {{Proceeding of the 4th International Conference on Universal Access in Human-Computer Interaction (UAHCI, as Part of HCI International, 2007), Beijing (China)}}, pages = {{537--546}}, publisher = {{Springer}}, title = {{{Easy Model-Driven Development of Multimedia User Interfaces with GuiBuilder}}}, doi = {{http://dx.doi.org/10.1007/978-3-540-73279-2_60}}, volume = {{4554}}, year = {{2007}}, } @inproceedings{7963, author = {{Bals, Jan-Christopher and Christ, Fabian and Engels, Gregor and Erwig, Martin}}, booktitle = {{Proceedings of the TOOLS Europe Conference (TOOLS 2007), Zürich (Swiss)}}, number = {{9}}, pages = {{383--398}}, publisher = {{Journal of Object Technology}}, title = {{{ClassSheets - model-based, object-oriented design of spreadsheet applications}}}, doi = {{http://www.jot.fm/issues/issue_2007_10/paper19/index.html}}, volume = {{6}}, year = {{2007}}, } @inproceedings{7964, author = {{Mlynarski, Michael and Hinkelmann, Knut and Magenheim, Johannes and Nelkner, Tobias and Reinhardt, Wolfgang and Holzweissig, Kai}}, booktitle = {{Creating New Learning Experiences on a Global Scale, Second European Conference on Technology Enhanced Learning, EC-TEL 2007, Crete, Greece, September 17-20, 2007}}, pages = {{487--492}}, publisher = {{Springer}}, title = {{{KnowledgeBus - An Architecture to Support Intelligent and Flexible Knowledge Management}}}, year = {{2007}}, } @inproceedings{7965, author = {{Förster, Alexander and Engels, Gregor and Schattkowsky, Tim and Van Der Straeten, Ragnhild}}, booktitle = {{Proceedings of the First Joint IEEE/IFIP Symposium on Theoretical Aspects of Software Engineering (TASE 2007), Shanghai (China)}}, pages = {{197--208}}, publisher = {{IEEE Computer Society}}, title = {{{Verification of Business Process Quality Constraints Based on Visual Process Patterns}}}, doi = {{http://dx.doi.org/10.1109/TASE.2007.56}}, year = {{2007}}, } @inproceedings{7966, author = {{Hess, Andreas and Humm, Bernhard and Voß, Markus and Engels, Gregor}}, booktitle = {{Proceedings of the 11th IEEE International Enterprise Distributed Object Computing Conference (EDOC 2007)}}, pages = {{122--129}}, publisher = {{IEEE Computer Society}}, title = {{{Structuring Software Cities - A Multidimensional Approach}}}, year = {{2007}}, } @inproceedings{7967, author = {{Mlynarski, Michael and Nelkner, Tobias and Reinhardt, Wolfgang}}, booktitle = {{Informatiktage 2007: Fachwissenschaftlicher Informatik-Kongress, 30. und 31.
