TL;DR: Reduced data collection, storage and communication requirements are found to lead to substantial reductions in the energy requirements of wireless sensor networks at the expense of modal accuracy.

TL;DR: In this article, a solar-powered wireless sensor network architecture that can be permanently deployed in harsh winter climates where limited solar energy and cold temperatures are normal operational conditions is demonstrated on a multi-steel girder bridge carrying northbound I-275 traffic over Telegraph Road.

TL;DR: A scalable and secure cyberinfrastructure platform termed SenStore is introduced for the management and automated analysis of sensing data, which includes a hybrid database architecture that maximizes query efficiency.

TL;DR: NoSQL database systems such as MongoDB and Apache Cassandra are employed to handle time-series data as well the unstructured bridge information model data and standard XML-based modeling languages such as OpenBrIM and SensorML are adopted to manage semantically meaningful data and to support interoperability.

TL;DR: In this article, electrical sensing methods, magnetic sensing, and acoustic emission are used to monitor structural damage in a segmental concrete pipeline during a large-scale test, and the results of this study indicate that electrical sensing method (including the use of conductive grout), magnetic sensing and acoustic emissions, employed alone or in combination, can detect and quantify the damage in segmentsal concrete pipelines.
