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 …

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 …

The Advantages Of Integrated Project Delivery (Ipd) Utilization In The Construction Industry Compared To Traditional Project Delivery Methods, Mert Oytun
