Numerical Analysis of Signal Response Characteristic of Piezoelectric Energy Harvesters Embedded in Pavement
(MDPI, 2020-06-18)Piezoelectric pavement energy harvesting is a technological approach to transform mechanical energy into electrical energy. When a piezoelectric energy harvester (PEH) is embedded in asphalt pavements or concrete pavements, ... -
mD-Resilience: A Multi-Dimensional Approach for Resilience-Based Performance Assessment in Urban Transportation
(MDPI, 2020-06-15)As demonstrated for extreme events, the resilience concept is used to evaluate the ability of a transportation system to resist and recover from disturbances. Motivated by the high cumulative impact of recurrent perturbations ... -
Estimation of the Intrinsic Power Efficiency in Magnetoelectric Laminates Using Temperature Measurements
(MDPI, 2020-06-11)Magnetoelectric (ME) power efficiency is a more important property than the ME voltage or the current coefficients for power conversion applications. This paper introduces an analytical model that describes the relation ... -
Comparison of Potential Contribution of Typical Pavement Materials to Heat Island Effect
(MDPI, 2020-06-10)Pavement materials have significant influence on the urban heat island effect (UHIE). This paper presents a study on the potential effects of pavement materials on UHIE in a natural environment. Three typical pavement ... -
Acoustic Energy Harvesting and Sensing via Electrospun PVDF Nanofiber Membrane
(MDPI, 2020-05-31)This paper introduces a new usage of piezoelectric poly (vinylidene fluoride) (PVDF) electrospun nanofiber (NF) membrane as a sensing unit for acoustic signals. In this work, an NF mat has been used as a transducer to ... -
Towards a Better Estimation of Inspection Intervals for Cracking Steel Railroad Bridges
(American Railway Engineering and Maintenance-of-Way Association, 2015-10-05)In order to best prioritize limited funds for railroad bridge capital and maintenance, it is important for the bridge engineer to have an accurate estimate of service life for existing steel bridges. In the context of the ... -
Fracture Resilience and Redundancy of Built-up Steel Girders
(American Institute of Steel Construction, 2016-04-15)Internal member redundancy provides built-up steel girders with the ability to resist total member failure in the event an individual component fails. Anecdotal evidence of in- service performance has historically shown ... -
Accelerated Corrosion Testing of ASTM A1010 Stainless Steel
(American Institute of Steel Construction, 2018-04-11)ASTM A1010 (recently adopted as ASTM A709 Gr50CR) is a material which has advantageous corrosion properties. It is a low-grade stainless steel which forms a protective patina and has been marketed as an alternative to other ... -
Determining typical buyer sensitivity for solar installation cost - Energy savings benefit
(American Solar Energy Society, 2012-12-31)A survey was conducted at the U.S. Department of Energy Solar Decathlon 2011 in Washington, DC to determine why American consumers have not yet adopted solar electric technology in their homes. With over 700 respondents, ... -
Perturbation-based balance training targeting both slip- and trip-induced falls among older adults: a randomized controlled trial
(2020-06-12)Abstract Background Falls are the leading cause of injuries among older adults. Perturbation-based balance training (PBT) is an innovative approach to fall prevention that aims to improve the reactive balance response ... -
Process-Guided Deep Learning Predictions of Lake Water Temperature
