Mass Manufacturing 8x20 Tiny Homes For Low Income Housing In Slo, Tyler James Morales

Construction Management

The United States housing prices have been on the rise for years. This increase has led to an extremely large number of citizens in this country who are unable to afford their rent, much less buy a home. One of the many potential solutions to this problem are tiny homes. Tiny homes have been around since the 1850’s but have just recently been thrusted back into the spotlight. Today Tiny Homes is more than a style of housing but a movement to return to simpler times and simpler lifestyles by living out of a much smaller home. Our project goal …

In Vitro Characterization Of Shape Memory Polymer Foam Hemostats, Nakira Hollinae Christmas

Theses - ALL

Shape memory polymer foam hemostats are a promising option for future hemorrhage control in battlefield wounds. To enable their use as hemostatic devices they must be optimized in terms of formulation and architecture and characterized in terms of safety and efficacy. As a device advances through the stages of development, pre-clinical testing is required in animals. In order to help mitigate the excess use of animals as well as decrease the costs of pre-clinical research, relevant in vitro models need to be created and used for device optimization. In the work conducted here, two in vitro models were created; a …

Validation Of Digital Surface Models (Dsms) Retrieved From Unmanned Aerial Vehicle (Uav) Point Clouds Using Geometrical Information From Shadows, Mahyar Aboutalebi, Alfonso F. Torres-Rua, Mac Mckee, William Kustas, Héctor Nieto, Calvin Coopmans

AggieAir Publications

Theoretically, the appearance of shadows in aerial imagery is not desirable for researchers because it leads to errors in object classification and bias in the calculation of indices. In contrast, shadows contain useful geometrical information about the objects blocking the light. Several studies have focused on estimation of building heights in urban areas using the length of shadows. This type of information can be used to predict the population of a region, water demand, etc., in urban areas. With the emergence of unmanned aerial vehicles (UAVs) and the availability of high- to super-high-resolution imagery, the important questions relating to shadows …

Multispectral Remote Sensing For Yield Estimation Using High-Resolution Imagery From An Unmanned Aerial Vehicle, Mahyar Aboutalebi, Alfonso F. Torres-Rua, Niel Allen

AggieAir Publications

Satellites and autonomous unmanned aerial vehicles (UAVs) are two major platforms for acquiring remotely-sensed information of the earth’s surface. Due to the limitations of satellite-based imagery, such as coarse spatial resolution and fixed schedules, applications of UAVs as low-cost remote sensing systems are rapidly expanding in many research areas, particularly precision agriculture. UAVs can provide imagery with high spatial resolution (finer than 1 meter) and acquire information in visible, near infrared, and even thermal bands. In agriculture, vegetation characteristics such as health, water stress, and the amount of biomass, can be estimated using UAV imagery. In this study, three sets …

Patterns in the strain loading were monitored to draw conclusions about …

3d Modeling Of Murine Abdominal Aortic Aneurysms: Quantification Of Segmentation And Volumetric Reconstruction, Paula A. Sarmiento, Amelia R. Adelsperger, Craig J. Goergen Ph.D.

The Summer Undergraduate Research Fellowship (SURF) Symposium

Abdominal Aortic Aneurysms (AAA) cause 5,900 deaths in the United States each year. Surgical intervention is clinically studied by non-invasive techniques such as computed tomography and magnetic resonance imaging. However, three-dimensional (3D) ultrasound imaging has become an inexpensive alternative and useful tool to characterize aneurysms, allowing for reconstruction of the vessel, quantification of hemodynamics through computational fluid dynamics (CFD) simulation, and possible prediction of aortic expansion and rupture. However, current analysis techniques for these images require the use of multiple software platforms for either modeling or simulation, prompting the need for alternatives to improve data processing. This study monitors the …

Evaluating The Effectiveness Of Cranial Molding For Treatment Of Positional Plagiocephaly Using Finite Element Analysis, Maziyar Keshtgar

Master's Theses

Since the advent of recommendations for placing infants in the supine position during sleep to reduce the incidence of sudden infant death syndrome, clinicians have noted an increase in the frequency of cranial asymmetry due to deformation of suture sections of the infants’ skulls as a result of constant concentrated stress in one area at the back of their head. This specific form of cranial deformation is known as positional plagiocephaly and its rate of occurrence has increased from 0.3% in 8.2% within the past 30 years.

Current treatments and methodologies for preventing and correcting positional plagiocephaly such as stretching …

Using Photogrammetry To Document, Analyze, And Reverse-Engineer Grave Markers, Robert Z. Selden Jr.

CRHR: Archaeology

There are a wide range of applications for three-dimensional (3D) data in archaeology, and a diverse array of methods for collecting and analyzing those data. In this article, free 3D photogrammetry software (Autodesk 123D Catch) is used to document a series of grave markers. The data are subsequently exported to Geomagic Design X to demonstrate and briefly discuss the various potential analyses that might be used to illustrate the effects of preservation treatments and marker degradation through time. Further, one marker is reverse-engineered, illustrating the capacity of 3D modeling to expedite the process of design, should elements warrant replacement. Additional …

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

Three-Dimensional Modeling Of The Plasma Arc In Arc Welding, Gu Xu, J. Hu, Hai-Lung Tsai

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Most previous three-dimensional modeling on gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) focuses on the weld pool dynamics and assumes the two-dimensional axisymmetric Gaussian distributions for plasma arc pressure and heat flux. In this article, a three-dimensional plasma arc model is developed, and the distributions of velocity, pressure, temperature, current density, and magnetic field of the plasma arc are calculated by solving the conservation equations of mass, momentum, and energy, as well as part of the Maxwell's equations. This three-dimensional model can be used to study the nonaxisymmetric plasma arc caused by external perturbations such as …
