Utilitarian Approaches For Multi-Metric Optimization In Vlsi Circuit Design And Spatial Clustering, Upavan Gupta

USF Tampa Graduate Theses and Dissertations

In the field of VLSI circuit optimization, the scaling of semiconductor devices has led to the miniaturization of the feature sizes resulting in a significant increase in the integration density and size of the circuits. At the nanometer level, due to the effects of manufacturing process variations, the design optimization process has transitioned from the deterministic domain to the stochastic domain, and the inter-relationships among the specification parameters like delay, power, reliability, noise and area have become more intricate. New methods are required to examine these metrics in a unified manner, thus necessitating the need for multi-metric optimization. The optimization …

Electrospray ionization is a technique widely used in mass spectrometry. Almost every material, specifically large molecules like proteins or polymers can be ionized directly out of solution. During the ionization process molecules are not fragmented. In this work a prototype apparatus for creating three-dimensional patterns in a ultra high vacuum environment using an electrospray ion source was optimized for higher ion currents hence deposition rate by improving the core component of the apparatus, an electrodynamic ion funnel. The major improvements are a redesigned heated vacuum inlet, modified gas flow inside the ion funnel because of sealing the ion funnel against …

Manufacturing Process Design And Control Based On Error Equivalence Methodology, Shaoqiang Chen

USF Tampa Graduate Theses and Dissertations

Error equivalence concerns the mechanism whereby different error sources result in identical deviation and variation patterns on part features. This could have dual effects on process variation reduction: it significantly increases the complexity of root cause diagnosis in process control, and provides an opportunity to use one error source as based error to compensate the others.

There are fruitful research accomplishments on establishing error equivalence methodology, such as error equivalence modeling, and an error compensating error strategy. However, no work has been done on developing an efficient process design approach by investigating error equivalence. Furthermore, besides the process mean shift, …

The Spatial Distribution Of Geoprivacy Concerns In Florida: A County Level Analysis, Joshua W. House

USF Tampa Graduate Theses and Dissertations

Certain types of spatial data maintained and distributed by counties at taxpayer expense can be used with powerful mapping and analysis software, called Geographic Information Systems (GIS), to compromise an indvidual's locational privacy. The kind of privacy at threat here is referred to as geoprivacy, which is concerned with the rights to prevent disclosure of the location of one's home, workplace, or daily activities. While the availability of accessible and accurate geospatial data has increased geoprivacy concerns in recent years, this threat remains virtually unknown to the general public.

Although previous research has explored various components of the geoprivacy …

“Pleasant Episodes” Of Gastronomy: Food And Drink In F. Scott Fitzgerald’S The Beautiful And Damned, Melissa Faith Dullaghan

USF Tampa Graduate Theses and Dissertations

This thesis explores the motif of gastronomy in Fitzgerald's critically undertreated second novel, The Beautiful and Damned. Within the discussion of the leisure class, Fitzgerald scholars often focus on Jay Gatsby's parties, but they seem to neglect Anthony Patch and company's fancy for food and drink in Ivy League supper clubs of Manhattan, vaudeville theaters, and houses of languor in Upstate New York. Building upon George J. Searles's article "The Symbolic Function of Food and Eating in F. Scott Fitzgerald's The Beautiful and Damned," this thesis examines the meaning of Fitzgerald's pervasive "prandial allusions" and character psychology with …

Micro-Autoradiographic Fusion Tomography, James Merker

USF Tampa Graduate Theses and Dissertations

Two-dimensional (2-D) micro-autoradiography is typically used to identify the location of a radio-labeled ligand bound to a cellular target in tissue sections. Data, such as a histological image, combined with the autoradiographic data provide a spatial relationship of the radiolabel to cellular structures. However, the disadvantage of 2-D imaging is that it only provides a local distribution of the radiolabel within a tissue slice, and not a volumetric regional distribution in the structure of interest. The development of 3-D autoradiographic/histological visualizations would provide important information not otherwise apparent, such as the ability to visualize the distribution of the labeled agents …

The Role Of Rala And Ralb In Cancer, Samuel C. Falsetti

USF Tampa Graduate Theses and Dissertations

Ras genes are frequently mutated in human cancers and present compelling targets for therapeutic intervention. While previous attempts to directly inhibit oncogenic Ras function have largely been unsuccessful use of targeted agents to inhibit the three primary oncogenic pathways activated by mutated Ras: RalGEF-Ral, PI3K-Akt and Raf- MEK-Erk, is an area of intense investigation. Here, we describe the ability of a novel pharmacological inhibitor of geranylgeranyltransferase I, GGTI-2417, to inhibit Ral prenylation and localization. We further used a Ral rescue system to selectively preserve RalA and RalB function and localization during GGTI-2417 treatment and determine the precise roles for inhibition …
