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.

Moreover, self- organizing systems show an overall behavior that cannot easily be predicted or even preprogrammed in a scalable way. It was in the early 1960ies that people like Ashby and Eigen investigated self-organization properties in (natural) systems. Since these days, a great number of (technical) solutions have been developed, which, either on purpose or unintentionally, inherently the basic concepts of self-organization. The aim of this book is to investigate the concepts of self-organization in the context of autonomous sensor and actor networks. The primary objective is to categorize the basic self-organization methods and to survey techniques for communication and coordination in massively distributed systems according to the developed classification scheme. Basically, two possible approaches can be thought of for organizing this book. First, we could start analyzing sensor and actor network technology and figure out what basic mechanisms are employed and how these relate to self-organization. A second approach would be to introduce self-organization as a methodology, apparently used everywhere in our life (in nature and in technical systems), and afterwards to continue with technical issues in sensor and actor networks searching for previously learned self-organization methods. I decided to follow the second approach in order to keep the focus on self-organization while studying the term in the world of sensor and actor networks. The term self-organization is still often misunderstood and misinterpreted. Therefore, this textbook is intended to be a basis for a better understanding of the concepts of self-organization, especially in the domain of sensor and actor networks. It provides a stepwise introduction of definitions, methodologies, and corresponding techniques relevant in the context of self-organization. Recent advances in miniaturization and wireless communication enabled the development of low-cost sensor nodes. Additionally, new application domains of sensor and actor networks emerged that demand for huge numbers of interacting devices. Thus, the relevance of self-organization methods is rapidly increasing as it is considered the primary control paradigm for distributed and massively distributed systems. The reader will see that self-organization has a number of advantages compared to other control paradigms. So, it becomes possible to operate huge numbers of collaborating subsystems even in case of limited resources, unreliable communication, and in case of massive failures of single systems. Unfortunately, these advantages are accompanied by some rather annoying side effects such as the increasing complexity and a nondeterministic behavior. By using optimal combinations of the basic methods of self-organization, these disadvantages can be minimized to some extent. According to the objective of this textbook - to study sensor and actor networks - the most relevant domains of communication and coordination are deeply investigated based on well-known algorithms and mechanisms and a number of case studies. This includes networking aspects of medium access control, ad hoc routing, data-centric communication, and clustering techniques. Additionally, control mechanisms for cooperation, task and resource allocation, and collaborative actuation are investigated. The book is concluded by a brief introduction of the domain of bio-inspired algorithms. This study is included for two reasons. First, to demystify the term bio-inspired networking, and secondly, to show the capabilities of such bio-inspired approaches. }}, author = {{Dressler, Falko}}, isbn = {{978-0-470-02820-9}}, publisher = {{John Wiley & Sons}}, title = {{{Self-Organization in Sensor and Actor Networks}}}, doi = {{10.1002/9780470724460}}, year = {{2007}}, } @article{16648, author = {{Padberg, Kathrin and Hauff, Thilo and Jenko, Frank and Junge, Oliver}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, pages = {{400--400}}, title = {{{Lagrangian structures and transport in turbulent magnetized plasmas}}}, doi = {{10.1088/1367-2630/9/11/400}}, year = {{2007}}, } @inproceedings{13173, author = {{Span, R. and Gerber, M. and Buljina, I. and Baumhögger, Elmar}}, booktitle = {{Boiling}}, isbn = {{1567002250}}, title = {{{POOL BOILING IN HIGHLY VISCOUS MIXTURES - DESIGN OF A NEW APPARATUS AND RESULTS OF PRETESTS}}}, doi = {{10.1615/ihtc13.p28.590}}, year = {{2007}}, } @article{29827, abstract = {{Die Entwicklung neuer Konfigurationen zur Rußabscheidung in Elektrofiltern im Hinblick auf Kfz-Applikationen bedingt die Notwendigkeit, diese auch mithilfe von Simulationen bewerten zu können. Der Beitrag stellt einen neuen Ansatz zur Simulation des Abscheideprozesses für einen Temperaturbereich bis 400 Grad C vor. Entscheidend ist die Möglichkeit, das raumladungsbehaftete elektrische Feld für alle Betriebszustände zu simulieren. Für den Transport der Raumladungen wird ein Ansatz aus der Mehrphasenströmungssimulation verwendet. Die Abscheidung der Partikeln wird mithilfe eines Lagrangeschen Ansatzes modelliert, der die zeitabhängige Aufladung unter lokalen elektrischen Bedingungen berücksichtigt. Die Simulation des Gesamtprozesses wird mit experimentellen Untersuchungen anhand eines Laborabscheiders verifiziert. Simulation und Experiment stimmen gut überein. Insbesondere der dominierende Einfluss durch die Bereiche in der Nähe der Platten konnte gut abgebildet werden. Das Gleiche gilt für die parabolische Form der Strom-Spannungs-Kennlinie. Weitere Untersuchungen sind erforderlich, um die gezeigten Methoden auf die Rußabscheidung zu übertragen.
