Demonstration includes 3 minutes demo of the software workbench with a case study and 2 minutes video showing PRODDIA main features and other results.
	EC Electronics	EC Electronics will demonstrate a new portable low-power battery operated wireless mechanical impedance sensor device PI-8000 (8 channels) to assess the condition of monitoring structure. Hotspot Monitoring of damage progression through real-time damage detection based on PI-8000 will be shown. PI-8000 system can be easily expandable up to 128 units.
	Georgia Institute of Technology	A 5-min video will be presented on our latest research exploiting mobile sensor networks for SHM. Integrating mobility with sensing nodes resolves some most critical challenges faced by current static wireless sensor networks. Multiple mobile sensing nodes form an organic mobile sensor network that can search for potential structural damage.
	Katholieke Universiteit Leuven	A live-demonstration of a percolation sensor for detecting the presence of corrosive liquids in floor beam/seat track structure of airplanes.
	Metis Design Corporation	MDC plans to demonstrate real-time damage detection on representative composite structure using 3 sensor node digital sensor network to cover the large specimen (over 1 m2), data will be wireless transferred to a laptop for fast visualization of the damage. Single as well as multiple damage events introduced simultaneously.
	Mistras Group, Inc.	The 4-channel Acoustic Emission wireless node is designed as a local area monitoring system capable of detecting damage onset or progression such as crack growth, active corrosion, delamination formation in composites, impact damage, etc.
	National Instruments	National Instruments would demonstrate a new low-power wireless sensor device for strain gages and show the programming of the intelligent wireless device for local data processing of strain data using LabVIEW.
	Optilab	Optilab will demonstrate how the FBG Sensor Interrogator (FSI), a measurement system for FBG based optical sensing applications, can simultaneously have low speed sensing with 0.1 pm resolution and high speed sensing of 200 Hz and up in a single chassis. Furthermore, Optilab will demonstrate scalability of this FSI and innovative C-based software that can be streamed to computers and mobile devices in a numerical, graphical 2D, or 3D model visual interface.
	Princeton University	Demonstrating Bridge Health Monitoring system to show live measurements to the audience and also show the "Playback" software for analysis of events showing important loading in the form of heavy truck and related deformation captured by cameras and sensors.
	Structures And Composites Laboratory	Structures and Composites Lab will demonstrate the importance of combination of offline training algorithms with real-time diagnostics for monitoring composite structures. Both damage classification and quantification models are the result of currently developed learning algorithms.
	Structure Inspection & Monitoring Inc.	Demonstrates the development of SIM Diagnostic Software, as part of Bridge Health monitoring system, to exploit the capabilities of smart sensors where the cost of data communications may be a major portion of the cost. The software reports data summaries on an exception basis to help engineers track changes not predicted from the latest model estimate stored at the data center.
	University of Michigan	This SHM-in-action demonstration will describe a permanent wireless monitoring system installed on the New Carquinez Bridge in Vallejo, CA. Access to the bridge monitoring system will be conducted to highlight the sensor network installed and to showcase variety of cyber infrastructure tools developed to support the automated interrogation of bridge response data.
	VCE GmbH	VCE would demonstrate how monitoring can influence Life Cycle Engineering. An example of the Life Cycle Software will be shown where changes in measurement or in management affect the Life Cycle Curve and therefore the predicted remaining lifetime in real time. This tool can help decision makers where and when to invest in their infrastructure to optimize costs and the state of preservation.

Objective:

To show how a structural health monitoring (SHM) system practically works. If you are working with SHM systems and would like to show in a short presentation how they practically work, then you shall participate. This presentation can be additional to exhibits or oral presentations and is specifically targeted to underline the practical aspect of the SHM.

Motivation:

There is a significant progress in SHM technology recently for a variety of applications. This presentation shall focus on how these SHM systems work in practice in terms of installation, handling, interpretation, and robustness for the following applications:

• operational loads monitoring,
• damage detection,
• health monitoring, and
• life cycle management.

The session targets at:

• showing the audience how SHM works in practical applications,
• better understanding the practical issues of different SHM systems,
• getting further feedback and requirements expressed from current and potential SHM users, and
• SHM users to share their experience.

Procedure:

The session intends to show as much of demonstration cases as possible, addressing as many of the aspects mentioned below:

• the way the monitoring system and the test is operated;
• type of sensors and actuators (if required) and their way of attachment to components, linkage to the signal generation and acquisition unit, etc.;
• signal generation and acquisition unit as a hardware and how it operates;
• the way input data are entered and sensor data are received and how the result is presented during the test;
• procedure for sensor signal processing;
• the 'man-machine interface' such as data input and output display;
• component(s) tested, area/volume to be monitored, loading procedure and the damage initially observed by conventional means of non-destructive testing;
• characteristics of the system such as weight, size, volume, reliability, cost, etc.

Each presentation is allowed no more than 5 minutes through a video, internet or a hardware live demonstration only , which will be directly displayed to the audience on a large screen. It is mandatory that the SHM system is shown in action. Static displays are not acceptable . Each presentation will be followed by a brief Q&A session where the SHM demonstrators must answer questions from the audiences.

The test cases being presented can be either based on self-developed or purchased SHM systems. The source of the SHM hardware is eligible to be mentioned but no further advertisement from or about the supplier of the SHM system will be accepted.

Any detailed background of the SHM system and the testing can be provided through the manuscript in the workshop proceedings. Provision of a manuscript in the proceedings is however not mandatory. Exhibitors can provide a direct video link to their booth at the workshop such that demonstrations can be made from there and can be directly transmitted to the audience via a screen.
