Eine solche Messung wird beispielsweise notwendig, wenn ein Geb{\"a}ude verst{\"a}rkt, erh{\"o}ht oder anders als bisher genutzt werden soll, aber keine Unterlagen mehr {\"u}ber die Fundamente vorhanden sind. Das Messprinzip des schon seit einigen Jahrzehnten bekannten Verfahrens ist relativ einfach: Auf dem Pfahlkopf wird meist durch Hammerschlag eine Stoßwelle erzeugt, die durch den Pfahl nach unten l{\"a}uft. Dabei wird Energie in den Boden abgegeben. Die abgestrahlten Wellen werden von Sensoren in einem parallel zum Pfahl hergestellten Bohrloch registriert. Aus den Laufzeiten lassen sich die materialspezifischen Wellengeschwindigkeiten im Pfahl und im Boden sowie die Pfahll{\"a}nge ermitteln. Bisher wurde meist ein sehr einfaches Verfahren zur Datenauswertung verwendet, das die L{\"a}nge der Pf{\"a}hle systematisch {\"u}bersch{\"a}tzt. In der vorliegenden Dissertation wurden die mathematisch-physikalischen Grundlagen beleuchtet und durch Computersimulation die Wellenausbreitung in Pfahl und Boden genau untersucht. Weitere Simulationen kl{\"a}rten den Einfluss verschiedener Mess- und Strukturparameter, beispielsweise den Einfluss von Bodenschichtung oder Fehlstellen im Pfahl. So konnte gekl{\"a}rt werden, in welchen F{\"a}llen mit dem Parallel-Seismik-Verfahren gute Ergebnisse erzielt werden k{\"o}nnen (z. B. bei Fundamenten in Sand oder Ton) und wo es an seine Grenzen st{\"o}ßt (z. B. bei Gr{\"u}ndung im Fels). Auf Basis dieser Ergebnisse entstand ein neuer mathematischer Formalismus zur Auswertung der Laufzeiten. In Verbindung mit einem Verfahren zur Dateninversion, d. h. der automatischen Anpassung der Unbekannten in den Gleichungen an die Messergebnisse, lassen sich sehr viel genauere Werte f{\"u}r die Pfahll{\"a}nge ermitteln als mit allen bisher publizierten Verfahren. Zudem kann man nun auch mit relativ großen Abst{\"a}nden zwischen Bohrloch und Pfahl (2 - 3 m) arbeiten. Die Methode wurde an simulierten Daten ausf{\"u}hrlich getestet. Die Messmethode und das neue Auswerteverfahren wurden in einer Reihe praktischer Anwendungen getestet - und dies fast immer erfolgreich. Nur in einem Fall komplizierter Fundamentgeometrie bei gleichzeitig sehr hoher Anforderung an die Genauigkeit war schon nach Simulationen klar, dass hier ein Einsatz nicht sinnvoll ist. Daf{\"u}r zeigte es sich, dass auch die L{\"a}nge von Pfahlw{\"a}nden und Spundw{\"a}nden ermittelt werden kann. Die Parallel-Seismik-Methode funktioniert als einziges verf{\"u}gbares Verfahren zur Fundamentl{\"a}ngenermittlung zugleich in den meisten Bodenarten sowie an metallischen und nichtmetallischen Fundamenten und kommt ohne Kalibrierung aus. Sie ist nun sehr viel breiter einsetzbar und liefert sehr viel genauere Ergebnisse. Die Simulationen zeigten noch Potential f{\"u}r Erweiterungen, zum Beispiel durch den Einsatz spezieller Sensoren, die zus{\"a}tzliche Wellentypen empfangen und unterscheiden k{\"o}nnen.}, language = {de} } @phdthesis{Boeniger2010, author = {B{\"o}niger, Urs}, title = {Attributes and their potential to analyze and interpret 3D GPR data}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-50124}, school = {Universit{\"a}t Potsdam}, year = {2010}, abstract = {Based on technological advances made within the past decades, ground-penetrating radar (GPR) has become a well-established, non-destructive subsurface imaging technique. Catalyzed by recent demands for high-resolution, near-surface imaging (e.g., the detection of unexploded ordnances and subsurface utilities, or hydrological investigations), the quality of today's GPR-based, near-surface images has significantly matured. At the same time, the analysis of oil and gas related reflection seismic data sets has experienced significant advances. Considering the sensitivity of attribute analysis with respect to data positioning in general, and multi-trace attributes in particular, trace positioning accuracy is of major importance for the success of attribute-based analysis flows. Therefore, to study the feasibility of GPR-based attribute analyses, I first developed and evaluated a real-time GPR surveying setup based on a modern tracking total station (TTS). The combination of current GPR systems capability of fusing global positioning system (GPS) and geophysical data in real-time, the ability of modern TTS systems to generate a GPS-like positional output and wireless data transmission using radio modems results in a flexible and robust surveying setup. To elaborate the feasibility of this setup, I studied the major limitations of such an approach: system cross-talk and data delays known as latencies. Experimental studies have shown that when a minimal distance of ~5 m between the GPR and the TTS system is considered, the signal-to-noise ratio of the acquired GPR data using radio communication equals the one without radio communication. To address the limitations imposed by system latencies, inherent to all real-time data fusion approaches, I developed a novel correction (calibration) strategy to assess the gross system latency and to correct for it. This resulted in the centimeter trace accuracy required by high-frequency and/or three-dimensional (3D) GPR surveys. Having introduced this flexible high-precision surveying setup, I successfully demonstrated the application of attribute-based processing to GPR specific problems, which may differ significantly from the geological ones typically addressed by the oil and gas industry using seismic data. In this thesis, I concentrated on archaeological and subsurface utility problems, as they represent typical near-surface geophysical targets. Enhancing 3D archaeological GPR data sets using a dip-steered filtering approach, followed by calculation of coherency and similarity, allowed me to conduct subsurface interpretations far beyond those obtained by classical time-slice analyses. I could show that the incorporation of additional data sets (magnetic and topographic) and attributes derived from these data sets can further improve the interpretation. In a case study, such an approach revealed the complementary nature of the individual data sets and, for example, allowed conclusions about the source location of magnetic anomalies by concurrently analyzing GPR time/depth slices to be made. In addition to archaeological targets, subsurface utility detection and characterization is a steadily growing field of application for GPR. I developed a novel attribute called depolarization. Incorporation of geometrical and physical feature characteristics into the depolarization attribute allowed me to display the observed polarization phenomena efficiently. Geometrical enhancement makes use of an improved symmetry extraction algorithm based on Laplacian high-boosting, followed by a phase-based symmetry calculation using a two-dimensional (2D) log-Gabor filterbank decomposition of the data volume. To extract the physical information from the dual-component data set, I employed a sliding-window principle component analysis. The combination of the geometrically derived feature angle and the physically derived polarization angle allowed me to enhance the polarization characteristics of subsurface features. Ground-truth information obtained by excavations confirmed this interpretation. In the future, inclusion of cross-polarized antennae configurations into the processing scheme may further improve the quality of the depolarization attribute. In addition to polarization phenomena, the time-dependent frequency evolution of GPR signals might hold further information on the subsurface architecture and/or material properties. High-resolution, sparsity promoting decomposition approaches have recently had a significant impact on the image and signal processing community. In this thesis, I introduced a modified tree-based matching pursuit approach. Based on different synthetic examples, I showed that the modified tree-based pursuit approach clearly outperforms other commonly used time-frequency decomposition approaches with respect to both time and frequency resolutions. Apart from the investigation of tuning effects in GPR data, I also demonstrated the potential of high-resolution sparse decompositions for advanced data processing. Frequency modulation of individual atoms themselves allows to efficiently correct frequency attenuation effects and improve resolution based on shifting the average frequency level. GPR-based attribute analysis is still in its infancy. Considering the growing widespread realization of 3D GPR studies there will certainly be an increasing demand towards improved subsurface interpretations in the future. Similar to the assessment of quantitative reservoir properties through the combination of 3D seismic attribute volumes with sparse well-log information, parameter estimation in a combined manner represents another step in emphasizing the potential of attribute-driven GPR data analyses.}, language = {en} } @article{YanKlieglShuetal.2010, author = {Yan, Ming and Kliegl, Reinhold and Shu, Hua and Pan, Jinger and Zhou, Xiaolin}, title = {Parafoveal load of word N+1 modulates preprocessing effectiveness of word N+2 in chinese reading}, doi = {10.1037/a0019329}, year = {2010}, language = {en} } @article{YanKlieglRichteretal.2010, author = {Yan, Ming and Kliegl, Reinhold and Richter, Eike M. and Nuthmann, Antje and Shu, Hua}, title = {Flexible saccade-target selection in Chinese reading}, issn = {1747-0218}, doi = {10.1080/17470210903114858}, year = {2010}, abstract = {As Chinese is written without orthographical word boundaries (i.e., spaces), it is unclear whether saccade targets are selected on the basis of characters or words and whether saccades are aimed at the beginning or the centre of words. Here, we report an experiment where 30 Chinese readers read 150 sentences while their eye movements were monitored. They exhibited a strong tendency to fixate at the word centre in single-fixation cases and at the word beginning in multiple-fixation cases. Different from spaced alphabetic script, initial fixations falling at the end of words were no more likely to be followed by a refixation than initial fixations at word centre. Further, single fixations were shorter than first fixations in two-fixation cases, which is opposite to what is found in Roman script. We propose that Chinese readers dynamically select the beginning or centre of words as saccade targets depending on failure or success with segmentation of parafoveal word boundaries.}, language = {en} } @article{KlieglWeiDambacheretal.2010, author = {Kliegl, Reinhold and Wei, Ping and Dambacher, Michael and Yan, Ming and Zhou, Xiaolin}, title = {Experimental effects and individual differences in linear mixed models: estimating the relationship between spatial, object, and attraction effects in visual attention}, doi = {10.3389/fpsyg.2010.00238}, year = {2010}, language = {en} } @book{Schmidt2010, author = {Schmidt, Thorsten Ingo}, title = {Verfassungsprozessrecht}, series = {Pr{\"u}fe dein Wissen : Rechtsf{\"a}lle in der Frage und Antwort}, volume = {34}, journal = {Pr{\"u}fe dein Wissen : Rechtsf{\"a}lle in der Frage und Antwort}, publisher = {Beck}, address = {M{\"u}nchen}, isbn = {978-3-406-60336-5}, pages = {266 S.}, year = {2010}, language = {de} } @phdthesis{Ganzert2010, author = {Ganzert, Lars}, title = {Bacterial diverity and adaption in permafrost-affected soils of maritime Antartica and Northeast Greenland}, address = {Potsdam}, pages = {104 S.}, year = {2010}, language = {en} }
