Tensor factorization in civil infrastructure systems
… to collect huge amounts of data generated from civil infrastructure systems. The conventional approach for analyzing structured data of this nature is to impose a matrix- structure on the data before analysis is done. Analysis tasks may include classification, clustering, regression and …

Advancements in Satellite SAR Methods for Monitoring Civil Infrastructure
… enables large-scale, remote monitoring of civil infrastructure. SAR allows for monitoring without installation or maintenance, unlike traditional contact-type sensors. Whilst SAR interferometry (InSAR) is widely used for land monitoring, its application to bridge monitoring is still …

Long-Term Performance of Polymeric Materials in Civil Infrastructure
Polymeric materials are popular in civil infrastructure due to their durability, strength, and resistance to corrosion and environmental degradation. However, the long-term performance of such materials in civil infrastructure is still being researched and investigated. This thesis will focus on …

Robotic Inspection Using Learning Based Impact Echo For Civil Infrastructure
<p>Concrete infrastructure often develops a variety of internal flaws that cannot be detected through visual inspection alone, and must be regularly inspected with other methods to maintain structural integrity. Impact echo (IE) is an acoustic non-destructive evaluation (NDE) technique essential …

Sudden-event monitoring of civil infrastructure using wireless smart sensors
Many of the civil infrastructure damage scenarios involve sudden events, including natural disasters and anthropogenic hazards. Due to their unpredictable nature, many of these events go unnoticed or unreported; but their consequence can be catastrophic, resulting in damage/failure in a matter of …

Improving the Design of Civil Infrastructure Messages for the Public
Civil infrastructure serves as the driving force behind the evolution of a safe, sustainable, and efficient environment. However, the way information about civil infrastructure has been communicated to the public has been insufficient. Since every human is intrinsically different, designing, and …

Vibration based health monitoring of civil infrastructure using energy harvesting techniques
The use of structural health monitoring of civil structures is ever expanding and by assessing the dynamical condition of structures, informed maintenance management can be conducted at both individual and network levels. With the continued growth of information age technology, the potential arises …

Adaptive data analysis for damage detection and system identification in civil infrastructure
… structural systems are often encountered in civil engineering. As extreme events occur more frequently and severely in recent years, more structures are loaded beyond their elastic conditions and may thus experience damage in the years to come. Even if structures remain elastic, energy …

Directed biogenic fabrication : programming cells and their ecosystems to grow civil infrastructure
… framework for co-fabricating ecologically active civil infrastructure with living cells. I propose that imbuing our buildings and urban systems with life, or at least biologic capabilities, will enable tight interconnections between fundamental species occupying different infrastructural niches, …

Machine Learning Based Analysis Of Civil Infrastructure In The Presence Of Sparse Data
<p>The high computational cost of estimating engineering demand parameters (EDPs) via finite element (FE) models, which incorporate uncertainties in earthquake events and material properties, limits the application of the Performance-Based Earthquake Engineering (PBEE) framework. Previous efforts …
