Los Molinitos De La Gente: Arquitectura Popular En El Río Grande Del Norte, 1600-1950, José A. Rivera, Levi Romero

Faculty Publications

For centuries, acequias and small grist mills in northern New Mexico villages played a major role in the agricultural economy of the region following the introduction of wheat from the Old World to the Americas. Wheat, in its ground form as flour, was a staple during the Spanish colonial period of the region. To process raw wheat, local mills (molinos) were essential infrastructure as were the acequias (ditches) that powered them. Most molinos were built from logs and were situated near the banks of watercourses. The wheel and axle were driven by the gravity force of water drawn …

Three-Dimensionalization Mediates The Subjective Experience Of Fractal Interior Spaces, Joori Suh, William Stalker, Steen Pedersen, Assaf Harel

Psychology Faculty Publications

A fractal, a self-similar organic or geometric pattern that repeats at varying scales, is one of the most compelling characteristics found in nature. Previous studies on fractal patterns have demonstrated consistent trends in potential psychological benefits, such as stress reduction. However, we fall short of understanding one of the essential properties of fractals found in nature, i.e., the three-dimensionality of their appearance. In this study, we aimed at understanding the role of the three-dimensionalization of fractal patterns in spatial structures on human subjective perceptual experience. Two hundred seventy three-dimensional spatial prototype models were created for this study, spanning two dimensions: …

Engineering-Enhanced Theatre: How Engineering Involvement Can Aid Regional Theatres, Albert M. Le

Architectural Engineering

Engineering and theatre are disciplines not often associated with each other within regional and small theatre companies in the United States. The distinction between the two fields of study is not simply from the fundamental differences between how each field is taught and practiced, but also the difficulties encountered within a scope of theatre often constrained with limited budget and time for each production. However, when beginning to explore the intersection between engineering and theatre, it is found that the empirical nature of current theatrical practices can be countered, and scenic design and construction can be re-envisioned with engineering involvement …

Settling Dust, Unsettling Ground, Olivia Newroz

Masters Theses

Understanding dust as a material system that blurs the line between ground and atmosphere, I developed a dust machine as a tool for making dust legible at the human scale. While the blurriness of ground is visualized at both particle and planetary scales, at the human scale, it becomes less evident. Drawing from Lisa’s Moffitt’s discussion of “environmental models”–that is, models that don’t merely simulate phenomena, in this case dust, but rather produce the underlying force itself––I produced visualizations of how dust, as both a grounded and atmospheric element, intertwines ground and weather across scales, through a cyclical process of …

In Pursuit Of Eye Tracking For Visual Landscape Assessments, David Evans, Brent Chamberlain

Landscape Architecture and Environmental Planning Faculty Publications

Visual quality and impact assessments have historically relied on experts to formally evaluate the visual properties of a landscape. In contrast, environmental psychologists have studied subjective landscape preferences using ratings and surveys. These two approaches represent, respectively, the “objectivist” and “subjectivist” paradigms within visual landscape research. A gap, however, exists between these approaches: actual observation behaviors. In this paper, we argue for the inclusion of eye-tracking research in visual landscape assessments as a critical bridge between objective landscape qualities and subjective visual experiences. We describe the basics of eye-tracking methods and data types to introduce the role of eye movements …

Indefinability Of Effective Stress For Unsaturated Soils, Xiong Zhang, Sandra Houston

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

For decades, researchers have searched for an unsaturated soil effective stress that performs analogously to effective stress for saturated soils and provides some simplifications over net stress and suction approaches. A recent debate is whether problems identified with unsaturated soil effective stress can be resolved via elastoplastic analyses. Effective stress equations are reviewed and categorized as being based on volume change, shear strength, yield, or degree of saturation. These equations are evaluated for consistency with saturated soil effective stress expectations using the Barcelona basic model (BBM), simplified into an integrated elastoplastic framework using the modified state surface approach (MSSA).
