Condition Rating Prediction Using An Interactive Deterioration Model Development Package, Minwoo Chang, Mitchell S. Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents an advanced method to determine explanatory variables required for developing deterioration models without the interference of human bias. Although a stationary set of explanatory variables is ideal for long-term monitoring and asset management, the penalty regression results vary annually due to the innate bias in the inspection data. In this study, weighting factors were introduced to consider the inspection data collected for several years, and the most stationary set was identified. To manage the substantial amount of inspection data effectively, we proposed a software package referred to as the Deterioration Model Development Package (DMDP). The objective of …

Framework For Extracting And Characterizing Load Profile Variability Based On A Comparative Study Of Different Wavelet Functions, Andrew Parker, Kevin James, Dongming Peng, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

The penetration of distributed energy resources (DERs) on the electric power system is changing traditional power flow and analysis studies. DERs may cause the systems' protection and control equipment to operate outside their intended parameters, due to DERs' variability and dispatchability. As this penetration grows, hosting capacity studies as well as protection and control impact mitigation become critical components to advance this penetration. In order to conduct such studies accurately, the electric power system's distribution components should be modeled correctly, and will require realistic time series loads at varying temporal and spatial conditions. The load component consists of the built …

Can Public Construction And Demolition Data Describe Trends In Building Material Recycling? Observations From Philadelphia, Kimberlee Marcellus-Zamora, Patricia Gallagher, Sabrina Spatari

College of Architecture and the Built Environment Faculty Papers

There is a significant amount of waste generated during construction and demolition (C&D) activities, but few data to understand the sources, age, spatial origin, and its fate following entry into the waste management system. With few public records that track C&D waste flows, we turned to industry and Leadership in Energy and Environmental Design (LEED) to quantify C&D data and meta-data using material flow analysis (MFA). LEED databases are not normally used to build life cycle inventories or material flow accounts because they do not house sufficiently detailed data. We propose using the geo-referenced data on reused C&D waste in …

Multimodal Transit And A New Civic Architecture, Samuel Bruce Hill

Masters Theses

We live in an age defined by the automobile and its infrastructure. This paradigm of movement has shaped how we live our lives, and the urban frameworks we inhabit. Cars as a form of transportation damage the environment and engender unsustainable lifestyles. They also create anti-social spaces with the infrastructure they require, and therefore their success is inverse to that of the pedestrian experience.

I seek to adapt this transit paradigm with a more flexible and resilient multimodal system. My work focuses on reinvigorating a rail line in central Massachusetts and designing a modular station system that can serve as …
