Ultra-wideband miniaturized microstrip patch antennas for wireless communications: design guidelines and modeling
(2013)
and radiation pattern of the UWB microstrip patch antenna is extensively investigated with simulations using FEKO. A set of simple design guidelines is proposed to provide approximate rules that result in optimum "first-pass" designs of probe-fed, miniaturized...
Laser target triggering of gas switches
(University of Missouri--Columbia, 2008)
Laser target triggering has been investigated at the University of Missouri as a method to reduce the laser energy required to trigger a laser triggered gas switch. Laser targets were solid materials embedded into the cathode of a LTGS that acted...
Gravitomagnetic Jets
(arXiv, 2010)
We present a family of dynamic rotating cylindrically symmetric Ricci-flat gravitational fields whose geodesic motions have the structure of gravitomagnetic jets. These correspond to helical motions of free test particles ...
The precision of retrieving temporal information : behavioral and electrophysiological studies
(University of Missouri--Columbia, 2020)
The knowledge of when an event took place provides benefits to episodic memory, such as distinguishing among multiple traces and learning event sequences. As a tool for understanding memory, time is appealing given its ...
Simulation algorithms for fractal radiation
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis presents a method to analyze a series of structures, referred to as fractals, that radiate electromagnetic waves. The fractal series are components of the so...
Writing on the wall : late-third century urban defenses in south Languedoc
(University of Missouri--Columbia, 2009)
The movement from the Roman to the medieval world is one of the most significant transitional moments of Western history. One of the most visible aspects of that transition is the installation of circuit walls that transform ...
Effects of temperature, photoperiod, and substrate on the maturation and reproductive behavior of the Topeka shiner (Notropis topeka)
(University of Missouri--Columbia, 2008)
The Topeka shiner (Notropis topeka) is a federally-listed endangered cyprinid species native to small headwater prairie streams in the mid-west of the United States. It generally spawns over and around sunfish (Lepomis ...
Structural variation at the KIT locus is responsible for the piebald phenotype in Hereford and Simmental cattle
(University of Missouri--Columbia, 2014)
animals homozygous and heterozygous for spotted and non-spotted alleles or extensive experimentation with developing embryos....
The early imperial ceramics as evidence for life at Roman Sardis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Historical testimonia tell us that in the year 17 CE, an earthquake struck in Western Asia Minor and destroyed the city of Sardis. Recent excavations in the Field 49, Field 55...
Functional characterization of two putative mobile elements of the 'Mycoplasma mycoides cluster'
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Horizontal gene transfer has played a major role in bacterial evolution, including in the genus Mycoplasma, which is comprised of some of the simplest and smallest free...
Classroom seating : applying Johnson's decision making inventory
(University of Missouri--Columbia, 2007)
Over a period of three weeks students in an introductory Parks and Recreation course were studied to determine their decision making styles, seating choice and movement. Data were collected on the first day of class to ...
Predictors of academic success for conditionally admitted first-time freshmen at a four-year public university
(University of Missouri--Columbia, 2010)
This quantitative study examined a sample of 249 conditionally admitted firsttime freshman at a four year public university to answer four research questions pertaining to the potential prediction of academic success and college retention...
Taphonomic characteristics of fossils on the burgessshale-type spectrum
(University of Missouri--Columbia, 2018)
"Study of exceptional fossil preservation tends to yield exciting results. Since soft-bodied organisms and the soft tissues of biomineralizing organisms are usually not preserved in the fossil record, instances of soft-tissue ...
Value addition to acid whey from Greek yogurt processing with millets (kodo and proso) for development of nutritious food products
(University of Missouri--Columbia, 2022)
The disconnect between massive demand and abundant supply of food has resulted in millions of people suffering from hunger and billion metric tons of food being wasted. Circular food economy could be a solution to the problem, whereby...
Application of a digital terrain model for forrest land classification and soil survey
(University of Missouri--Columbia, 2004)
Models (DEM's) to produce Digital Terrain Models (DTM's) in the Missouri Ozarks. Terrain models produced from several DEM sources were evaluated for their accuracy in predicting slope, aspect and landforms on a 3691 ha area. The DEM's created from USGS...
Assessing costs and environmental impacts of municipal food waste treatment options in Columbia, Missouri : a decision support tool integrating life cycle analysis and robust optimization
(University of Missouri--Columbia, 2021)
and targets, decisionmakers need data-driven analysis to understand both the costs and environmental impacts of their plans. This study develops a decision support tool applied in Columbia, Missouri, USA, with aims to model the economic and environmental...
Numerical Analysis of Helical and Log-periodic Antennas for Short Pulse Applications
(2020)
The planar log-periodic (LP) and helical antennas are numerically studied as two antennas with a wide range of applications. The advantages of the LP antenna are the large adjustable bandwidth as a frequency independence ...
Modeling of molecular and particulate transport in dry spent nuclear fuel canisters
(University of Missouri--Columbia, 2007)
There are two important phenomena associated with the depressurization of a dry spent nuclear fuel canister after the formation of a through-wall pinhole breach. The first phenomenon is the release from the canister of any ...
