Bearing Capacity
(2014-02-06)
The pressure that a foundation unit can impose onto the supporting earth mass without causing overstressing (or shear failure) is the soil's bearing capacity. The three principal modes of soil failure established by the ...
Atterburg Limits
(2014-02-06)
Atterberg Limits describe the water contents at which clays change behavior. The water content indicating the division between the liquid and plastic state is the liquid limit. The Liquid Limit is determined using a brass ...
Unconfined Compression Test
(2014-02-06)
The unconfined compression test. Collect approcimately 1200g of soil passing through the No. 4 Sieve. Add water and mix soil sample thoroughly. Weigh empty Harvard Miniature Mold and place layer of soil in mold. Compact ...
Categorizing Sedimentary Rocks by Origin
(2014-02-06)
Using examples, this video tells students what to look for in order to identify rocks.
On the Characterization and Reduction of Ill-Conditioning in Jointly Estimating Proton Density, T2* Decay and the Field Map
(2014-02-13)
We employ principal angles as a tool to demonstrate that the complex frequency is the main cause for ill-conditioning of model-based MRI reconstruction. We show that kernels of EPI and spiral trajectories have different ...
Characterization of Plenoptic Imaging Systems and Efficient Volumetric Estimation from Plenoptic Data
(2015-01-13)
Plenoptic imaging is a rapidly growing field driven
by the ever-declining cost of imaging systems and the promise
of image focus, perspective, and depth of field manipulation
during post-processing. While plenoptic ...
An efficient auxiliary variable method for quantification of spin density, R2* decay and field inhomogeneity maps in magnetic resonance imaging
(2015-04-07)
Quantification of spin density, $R_2^*$ decay and off-resonance frequency maps is very important in some applications of magnetic resonance imaging (MRI). To reconstruct these parameter maps, a time-varying model such as ...
Trust region methods for estimation of a complex exponential decay model in MRI with a single-shot or multi-shot trajectory (in review)
(2015-05-05)
Joint estimation of spin density, R2* decay and off-resonance frequency maps is very useful in many magnetic resonance imaging (MRI) applications. The standard multi-echo approach can achieve high accuracy but requires a ...
A Solution of Rigid Perfectly Plastic Deep Spherical Indentation based on Slip Line Theory
(2015-11-16)
During indentation it is often important to determine the relationship between the average pressure and the yield strength. This work uses slip line theory to determine this relationship for the case of a rigid sphere ...
Forest restoration as a strategy to mitigate climate impacts on wildfire, vegetation, and water in semiarid forests
(2020-05-18)
Climate change and wildfire are interacting to drive vegetation change and potentially reduce water quantity and quality in the southwestern United States, Forest restoration is a management approach that could mitigate ...
Field‐based robotic phenotyping of sorghum plant architecture using stereo vision
(2020-02-24)
Sorghum (Sorghum bicolor) is known as a major feedstock for biofuel production. To improve its biomass yield through genetic research, manually measuring yield component traits (e.g. plant height, stem diameter, leaf angle, ...
AU Smart Cart Senior Design Project Report Fall 2012
(2017-10-26)
Team 3 consists of six members working together to design and build a fully autonomous shopping cart. The purpose of the cart is to perform as a personal shopping assistant to the user as he/she shops in different environments. ...
Discrimination experiments with the U.S. Army's standard metal detector
(2022-10-25)
[1] Discrimination experiments with the U. S. Army's standard hand-held metal detector (AN/PSS-12) are described. An appendix describes the functioning of the device as a metal detector, and the body of the paper discusses ...
The electrostatic characterization of an n-element planar array using the singularity expansion method
(2022-09-28)
In this paper, the singularity expansion method (SEM) is used to describe the electrostatic charge distribution on an array of thin linear antennas placed in a uniform electric field. The SEM, which has primarily been used ...
UNSATURATED-ZONE WATER
(2022-10-11)
Experimental and numerical investigation of saltwater intrusion dynamics in flux-controlled groundwater systems
(2020-08-20)
Sea level rise and reduction of groundwater fluxes due to changes in rainfall patterns are the two major climate change–induced hydrological variables that can severely affect saltwater intrusion in coastal aquifers. In ...
Noble gas abundance and isotope ratios in the atmosphere of Jupiter from the Galileo Probe Mass Spectrometer
(2020-06-30)
The Galileo Probe Mass Spectrometer provided the first data on the noble gas mixing and isotope ratios in the Jovian atmosphere. These measurements and the comparison with solar values constrain models of Jupiter's formation. ...
Estimating the Center of Rotation of Tomographic Imaging Systems with Limited Projections
(2021-04-02)
For a tomographic imaging system, image reconstruction quality is highly correlated with accurate determination of the true center of rotation (COR) location. A significant center offset error will introduce ringing, ...
Data for: Comparison of two dielectric sensors in coarse-grained soils of increasing salinity
(2023-07-12)
Moisture content can impact the resilient modulus of pavement base course and subgrade layers. Given its influence on the post-inundation resilient moduli of the coastal pavement and base course and subgrade layers, it is ...
