Heritagutopia: A New Utopian Paradigm, Luca Donner, Francesca Sorcinelli Dec 2024

Heritagutopia: A New Utopian Paradigm, Luca Donner, Francesca Sorcinelli

All Works

The progress of humanity has always, and sometimes even unconsciously, been confronted with the concept of utopia at the social, economic, political, and urban level. The strength of every utopian vision lies in the disruptive factor inherent in the idea of metamorphosis of the status quo. In the urban context, it represents the pillar on which the vision of modern society and its city are based and understood as potential and progress for mankind. Authors such as Bauman, Bloch, Calvino, More, Mumford, Tafuri, and others, have formed the theoretical framework of the dialectic on which this study is based. As …

Memoryscapes: A Study Of Memory And Experience In Architecture, Jacob Granger May 2024

Memoryscapes: A Study Of Memory And Experience In Architecture, Jacob Granger

Architecture Masters of Science Program: Theses

Thesis statement

Architecture and urban spaces are fundamental in shaping both personal and collective memories, serving as the physical manifestations of narratives that define and inform community identity and individual experiences. This thesis asserts that urban design and architectural features extend beyond their utilitarian functions to actively craft and influence these memories. By intertwining intentional design with memory, architecture not only reflects but also molds our understanding of communal identity and historical narratives. This perspective offers a unique exploration of the interplay between tangible structures and the intangible experiences they foster, illustrating how architecture does not merely mirror reality but …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The rapid development of marine concrete structures and the sharp shortage of freshwater resources contribute to the wide investigation of seawater-mixed ultra-high-performance concrete (swuhpc). However, few studies have investigated the chloride ions (cl-) binding mechanism of swuhpc. Herein, the chloride binding experiments and molecular dynamics (md) simulation were carried out to reveal the physically and chemically bound cl- mechanisms of swuhpc. The results of the experiments clearly demonstrate that the addition of silica fume (sf) led to a significant decrease in the capacity of cl- binding. Conversely, the incorporation of metakaolin (mk) resulted in a marked increase in the content …

Planning Masters Professional Reports

The climate is warming at an alarming rate. This has brought many challenges to daily life in cities across the world. One of the most significant of these is intraurban heat and the Urban Heat Island Effect. Per The United States Environmental Protection Agency (EPA) website, urban heat islands are those urbanized areas that experience higher temperatures versus other outlying areas. As cities become more populated, this and resulting increased infrastructure will enhance the phenomenon. This in turn will exacerbate the negative consequences of this phenomenon to people as well as both the built and natural environments. As cities work …

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer May 2024

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer

Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research

Spatial hearing provides access to auditory spatial cues that promote speech perception in noisy listening situations. However, reverberation degrades auditory spatial cues and limits listeners’ ability to utilize these cues for segregating target speech from competing babble. Hence, spatial unmasking—an intelligibility benefit from a spatial separation between a target and masker—is reduced in reverberant environments as compared to free field. This work tests the hypothesis that interaural decorrelation, the result of increasing reverberation, will broaden the perceived auditory source width with a cascading effect of reduced auditory spatial acuity and subsequently poorer spatial unmasking. To understand the perceptual consequences of …
