Further Examination Of Moore's Law With Data Envelopment Analysis, Timothy R. Anderson, Rolf Färe, Shawna Grosskopf, Lane Inman, Xiaoyu Song

Engineering and Technology Management Faculty Publications and Presentations

Although it has stood the test of time for over 30 years, Moore's Law addresses but a single aspect of microprocessor design. As a proxy for technology, the number of transistors in an integrated circuit represents a limited perspective on the technology as a whole. Anderson et al. proposed a set of metrics by which to measure a technology, and a means to measure its progress over time utilizing data envelopment analysis. In this revised model, the assumption of state of the art (SOA) on product release is dropped, technical progress is measured iteratively over time, the effective time elapsed …

Determination Of Phase Composition Of Sputtered Tantalum On Steel Substrates By Resistivity Measurements, Younes Abbassi

Theses

The objective of this thesis was to develop a method of distinguishing between alpha and beta phases of tantalum films on steel substrates, using the four-point probe resistivity measurements. While there is a large difference between resistivities of the two Ta phases, the problem is challenging because the measurements are influenced by the low resistivity of steel.

For reference, the resistivity measurements of tantalum coatings (1-20 μm) on silicon and silicon dioxide substrates were conducted first. The measured resistivities were related to the crystallographic phase composition of Ta, which has lower resistivity in bcc form, α-phase, (13.5 to 42 μΩcm), …

Development Of A Method To Examine Shear Stress On Cardiomyocytes, Dhawal Desai

Theses

Cardiac hypertrophy is the remodeling or enlargement of the heart exhibited by individuals suffering from heart disease. Cardiac hypertrophy involves two mechanisms, mechanical stresses and humoral changes in the cardiac tissue. One such humoral change involves the Renin Angiotensin System (RAS). The primary fimction of RAS is maintenance of hemodynamics of the body mediated through an effector protein, Angiotensin 11. However, RAS has been shown to play a significant role in the pathophysiology of the heart; contributing to hypertension, cardiac hypertrophy and myocardial infarction. RAS acts through binding of Angiotensin 11 at its receptors. The two forms of Angiotensin 11 …

Genome-Wide Screening For Trait Conferring Genes Using Dna Microarrays, R. T. Gill, S. Wildt, Y. T. Yang, S. Ziesman, G. Stephanopoulos

Dartmouth Scholarship

We report a DNA microarray-based method for genome-wide monitoring of competitively grown transformants to identify genes whose overexpression confers a specific cellular phenotype. Whereas transcriptional profiling identifies differentially expressed genes that are correlated with particular aspects of the cellular phenotype, this functional genomics approach determines genes that result in a specific physiology. This parallel gene-trait mapping method consists of transforming a strain with a genomic library, enriching the cell population in transformants containing the trait conferring gene(s), and finally using DNA microarrays to simultaneously isolate and identify the enriched gene inserts. Various methods of enrichment can be used; here, genes …

Semiconductors are distinguished among all materials by having a non-vanishing energy band gaps. They are often used in industry in the form of alloys or heterostructures in order to tailor energy gaps suitable for the desired applications. In general, semiconductor materials have broad applications in industry, ranging from micro-electronic devices, to light emitters and detectors, to laser and solar cells. In the last two decades, particular attention has been given to the II-VI semiconductor heterostructures because of their suitability as photoelectronic devices covering from the infra-red to the ultra-violet spectral ranges. The scope of this thesis belongs to the field …

A Novel Membrane Process For Autotrophic Denitrification, Agnieszka Pierkiel

Theses and Dissertations

This research focused on the novel use of hollow fiber membranes for gas delivery in biological dentrification using hydrogen-oxidizing bacteria. Autotrophic denitrification is a biological process that reduces nitrate to nitrogen gas using an inorganic carbon source. Hydrogen gas is an electron donor and nitrate is the electron acceptor in the reaction. The specific research objectives were to:

• develop a mixed acclimated culture of hydrogen-oxidizing bacteria;
• evaluate biodegradation kinetics of the acclimated culture;
• evaluate hydrogen transfer characteristics of hollow fiber membrane modules;

and

• demonstrate technical feasibility of a continuous bioreactor-membrane system for denitrification.

The following kinetic coefficients were obtained: µ …

Use Of Positron Annihilation Spectroscopy For Stress-Strain Measurements, Ajit K. Roy

Transmutation Sciences Materials (TRP)

The purpose of this collaborative research project involving the University of Nevada, Las Vegas (UNLV) and Idaho State University (ISU) is to evaluate the feasibility of determining residual stresses of welded (after pre-straining) engineering materials using a new nondestructive technique based on positron annihilation spectroscopy. The proposed technique is to use γ-rays 2 from a small MeV electron Linac to generate positrons inside the sample via pair production. This method can be used for materials characterization and investigation of defects in thick samples that could not be accomplished by conventional positron techniques or other nondestructive methods. The data generated will …

Fisheries Management Report No. 6 - Proceedings Of Marron Farming Open Day 2002, Greg B. Maguire

Fisheries Published Reports

The marron industry is of considerable importance to the Department of Fisheries, being one of the older aquaculture industries in Western Australia, and one that accounts for around half the aquaculture licence holders in the State. While it has not grown as quickly as many hoped in the past, in 2000/01, some 52.2 tonnes of marron were produced, worth $1.18 million at the farm gate.

It is regionally significant, particularly in the south-west, and depending on appropriate site selection, has considerable potential in other areas. Farms are distributed from near Geraldton to around Bremer Bay, with additional interest around Esperance. …

Behavior Of Nano-Engineered Platelets In A Coronary Artery Stenosis Model, Hua Ai

Doctoral Dissertations

Cardiovascular disease is the leading cause of death in North America. Cardiac infarction caused by thrombus plaque rupture can often lead to sudden death. Arterial stenosis caused by atherosclerosis is an important precursor leading to thrombus formation. Shear stress, abnormal lipid metabolism, and subendothelial layer exposure are the major contributors to arterial thrombus formation. Platelet activation by the above factors, followed by adhesion is the basic sequence in thrombus formation.

Platelets were encapsulated with nanofilm in order to reduce platelet activation and adhesion under high shear stress. Polyions, nanoparticles and immunoglobulins were assembled in nano-organized shells on fixed bovine platelets …

Infopipes: An Abstraction For Multimedia Streaming, Andrew P. Black, Huang Jie, Rainer Koster, Jonathan Walpole, Calton Pu

Computer Science Faculty Publications and Presentations

To simplify the task of building distributed streaming applications, we propose a new abstraction for information flow – Infopipes. Infopipes make information flow primary, not an auxiliary mechanism that is hidden away. Systems are built by connecting predefined component Infopipes such as sources, sinks, buffers, filters, broadcasting pipes, and multiplexing pipes. The goal of Infopipes is not to hide communication, like an RPC system, but to reify it: to represent communication explicitly as objects that the program can interrogate and manipulate. Moreover, these objects represent communication in application-level terms, not in terms of network or process implementation.
