Settling characteristics of fractal aggregates
The settling velocity of aggregates found in engineered water and wastewater treatment facilities are usually assumed to follow Stokes' law. These particles, however, are typically porous and may be fractal in nature. As ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Bacteria and fullerene: The microbial response to fullerene water suspensions
The current nanotechnology boom necessitates timely research into the health and environmental impacts of nanomaterials to enhance their eco-responsible manufacture, use, and disposal. Using the water-insoluble C60 as a ...
Detroit continues to stand out as emblematic of failing urban economies, infrastructure, density, and form. But its spatially dominant urban relationships also provide the opportunity required to transform unsustainable, ...
Through an exploration of the architectural aperture, this thesis seeks to abandon a representational understanding of the image and restore a more performative one. Architecture’s imageability – its capacity to create ...
Sponge, Table, Pads: Exchange Space
This thesis takes the typical one-to-one relationship between a tower and a lobby and asks what if a three-layer base that produces a higher density and a scale exceeding the physical boundary of a single office tower ...
Towards a Greater [W]hole: Understanding Form in the City's Psyche
This thesis investigates the part-to-whole relationship in architectural and urban design, and the dialectic that exists between the conceptual and the perceptual in the built environment. Working with Gestalt principles ...
Exchange is at the core of public space. Whether trading products or sharing information, exchange between people produces social interactions and spatialized hubs of activity. Without exchange public spaces fail. Today, ...
Bioactive scaffolds for optimizing engineered tissue formation
Tissue-engineering scaffolds were designed to mimic several features of the extracellular matrix using a combination of the synthetic polymer, PEG diacrylate, and bioactive factors. Scaffolds were formed by exposing aqueous ...
A tunable laser-based mid-infrared source for use in trace gas detection
A new widely tunable mid-infrared (IR) source based on difference-frequency generation (DFG) in Gallium Selenide (GaSe) for use in high-resolution spectroscopy and trace gas detection is described. The characteristics of ...
