Historically, this area was the scene of a military skirmish which resulted in the unseating of the Spanish Governor of California, and his replacement by the Mexican leader Pio Pico.
Garden State Ballroom 9: Mr Xiangang Lai Co-Authors: Regency Ballroom ABC 9: NDE techniques have the potential to uncover internal defects as well as to estimate material properties with a relatively high spatial resolution at the material level.
Other approaches that are often referred to as Structural Health Monitoring SHM provide information at a somewhat lower spatial resolution but the measurements attempt to assess the overall behavior of a structure structural level assessment.
Both NDE and SHM share an inherent complexity and need proper understanding of the challenges, potentials, and shortcomings to extract reliable information. The authors are attempting to unveil some of these complexities to a relatively broad range of users including infrastructure owners, researchers, and industry stakeholders through the creation of a virtual laboratory website.
The creation of this virtual laboratory represents the primarily goal of an ongoing federally sponsored research study. The Virtual laboratory contains interactive modules where users can learn through simulations or observe real NDE data. The virtual laboratory also attempts to show how different tools can be integrated to improve the decision making process in infrastructure management through case studies on real operating infrastructures with performance concerns.
The paper provides highlights of the current content of the virtual laboratory. There are some presentation materials available for download.

Mr Roman Pinchuk Co-Authors: Ultrasonic material testing in its both functions — flaw detection and mechanical property evaluation — offers one of the possible instrumentation for the quality assurance in construction industry.
Due to its unique deep penetrating capability, ultrasonic testing in certain cases remains the only suitable method for evaluating internal structure of large constructions.
It allows extracting valuable additional information about slight acoustic impedance changes in the material by means of statistical processing of individual wavelets obtained by Dry Point Contact DPC transducer arrays and coherent integration of the impedance gradients.
In the current contribution, the basic principles of the new technique are explicated and few application cases are cited showing the potential of the novel approach for variety of practical ultrasonic inspection tasks in the construction industry. Print this page 9: Mr Sascha Feistkorn Co-Authors: This includes the assessment of the practical needs, typical inspection tasks as well as the limitations of the applied methods regarding their reliability and accuracy.
Among others, the analysis of former field inspections in Switzerland was carried out in more than 40 different individual projects as well as the development of new theoretical approaches.
Therefore, the research partners conducted an extensive study in collaboration with large construction companies to analyze the scope of NDT-CE methods applied in the past decades in Switzerland. As a result, the most relevant difficulties were identified depending on field conditions, such as reinforcement ratio, moisture content, tendon duct material or the size of a discontinuity of the component inspected.
To predict the success of a field inspection, the methods of POD Probability of Detection and GUM Guide to the Expression of Uncertainty in Measurement were used to quantify the performance and the accuracy of Radar and Ultrasound for common practical inspection tasks under different field conditions.
As one result, typical penetration depth values of GPR applied on concrete have been calculated. Furthermore, the estimated success of the respective methods is provided as a function of different field conditions.listing of classic documentary works in MRC.
