Zearalenone contamination in swine feed and the effects on reproductive health
(Virginia Tech, 2021-04-15)Zearalenone (ZEN) is an estrogenic mycotoxin produced by fungi in the genus Fusarium. Fusarium species commonly occur in cereal crops such as corn, wheat, barley, and rice which are used in swine feed. In addition to ... -
Zebra GC: A Fully Integrated Micro Gas Chromatography System
(Virginia Tech, 2014-08-29)A ready-to-deploy implementation of microfabricated gas chromatography (microGC) system characterized for detecting hazardous air pollutants (HAPs) at parts-per-billion (ppb) concentrations in complex mixtures has been ... -
Zero Divisors, Group Von Neumann Algebras and Injective Modules
(Virginia Tech, 2015-06-29)In this thesis we discuss linear dependence of translations which is intimately related to the zero divisor conjecture. We also discuss the square integrable representations of the generalized Wyle-Heisenberg group in 𝑛² ... -
Zero Quantum Nuclear Magnetic Resonance experiments utilizing a toroid cell and coil
(Virginia Tech, 1989-04-15)Over the past ten to fifteen years the area of Nuclear Magnetic Resonance (NMR) Spectroscopy has seen tremendous growth. For example, in conjunction with multiple quantum NMR, molecular structural mapping of a compound can ... -
Zero Voltage Switching (ZVS) Turn-on Triangular Current Mode (TCM) Control for AC/DC and DC/AC Converters
(Virginia Tech, 2020-01-10)One of the greatest technological challenges of the world today is reducing the size and weight of the existing products to make them portable. Specifically, in electric vehicles such as electric cars, UAVs and aero planes, ... -
Zero-pole interpolation of nonregular rational matrix functions
(Virginia Polytechnic Institute and State University, 1989)In this thesis the right and left pole structure of a not necessarily regular rational matrix function W is described in terms of pairs of matrices-right and left pole pairs. The concept of orthogonality in Rn ... -
Zero-voltage switched resonant and PWM converters: design-oriented analysis and performance evaluation
(Virginia Tech, 1994-04-26)The relative performance evaluation of the different alternatives of bridge topologies with zero-voltage switching is presented. A design-oriented analysis is developed to optimize implementation of the converters in terms ... -
Zinc distribution in a small stream receiving treated textile wastewater
(Virginia Tech, 1977-09-05)Effluent samples for a treated textile waste water and treated domestic sewage waste water and water and sediment samples for an 8.2 km region of Ash Camp Creek near Keysville, Virginia, were collected in June, 1977. ... -
ZnGa₂O₄ and ZnGa₂O₄:Mn²⁺ for potential use in vacuum fluorescent displays
(Virginia Tech, 1993-06-06)Zinc gallate and Mn²⁺-activated zinc gallate were identified as potential low-voltage cathodoluminescent phosphors for use in vacuum fluorescent displays. The stability of these oxide phosphors in high-vacuum and absence ... -
Zone Based Scheduling: A Framework for Scalable Scheduling of SPMD parallel programs on the Grid
(Virginia Tech, 2003-06-16)Grid computing is a field of research that combines many computers from distant locations to form one large computing resource. In order to be able to make use of the full potential of such a system there is a need to ... -
A Zone-Based Multiple Regression Model to Visualize GPS Locations on a Surveillance Camera Image
(Virginia Tech, 2015-06-17)Surveillance cameras are integral in assisting law enforcement by collecting video information that may help officers detect people for whom they are looking. While surveillance cameras record the area covered by the camera, ... -
Zoning's Connection with Racial Distribution: A Case Study on the Washington, D.C. MSA
(Virginia Tech, 2007-03-29)Zoning, as a public land-use tool, has several important goals. As zoning accomplishes these goals, however, zoning has had the unintended outcome of guiding high numbers of minorities into certain areas in which multi-family ... -
Zoo exhibit design: the influence of animal visibility on visitor experience
(Virginia Tech, 1996)Naturalistic exhibits have become popular among zoo designers as well as zoo visitors. However, one problem associated with naturalistic exhibits is that many times visitors cannot see the animals. The primary purpose of ... -
Zoomorphic Architecture: The Carolina Coastal Museum
(Virginia Tech, 2002-07-09)Throughout the evolution of man, the ocean has played an integral part in his survival. As technology has advanced so has man's use of the ocean. In order to preserve the history of these advancements for future generations, ... -
ZxOS: Zephyr-based Guest Operating System for Heterogeneous ISA Machines
(Virginia Tech, 2022-03-04)With the fast-approaching limits of single-threaded CPU performance, chip vendors are manufacturing an array of radically different computing architectures, including multicore and heterogeneous architectures, to continue ... -
A Zynq-based Cluster Cognitive Radio
(Virginia Tech, 2014-07-25)Traditional hardware radios provide very rigid solutions to radio problems. Intelligent software defined radios, also known as cognitive radios, provide flexibility and agility compared to hardware ...
