Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin Jan 2008

Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin

Graduate Theses, Dissertations, and Problem Reports (ETD)

In material nano- and micro-indentation research, Young's modulus can be obtained based on the initial unloading stiffness of the load-depth curve. The accurate load and displacement measurement as well as high precision position control of the indenter are needed to achieve the required measurement resolution. The application of PZT actuator is often used to perform the indentation experiment. However, conventional PZT controllers can only provide displacement control. Furthermore, each PZT actuator only serves a specific PZT controller using its unique calibration factor. Thus, it is beneficial to develop a controller, which can carry out both load and displacement control algorithm, …

Protein Degradation In Mammalian Hibernator, Spermophilus Lateralis, Vanja Velickovska Jan 2008

Protein Degradation In Mammalian Hibernator, Spermophilus Lateralis, Vanja Velickovska

UNLV Retrospective Theses & Dissertations

Protein synthesis is virtually non-existent during hibernation in golden-mantled ground squirrels. In the presence of negligible protein synthesis continued protein degradation would disrupt the maintenance of homeostasis and the survival of the animal. Earlier investigation showed that ubiquitin conjugate concentrations increase 2-3 fold during hibernation, which would seemingly suggest an increase of protein degradation. In this study I examined protein degradation per se as a function of the temperatures experienced by the hibernator and demonstrated that protein degradation is virtually absent at low temperatures. A new method was developed to determine the rates of ubiquitylation as a function of temperature, …


The Effects Of Automated Essay Scoring As A High School Classroom Intervention, Kathie L Frost Jan 2008

The Effects Of Automated Essay Scoring As A High School Classroom Intervention, Kathie L Frost

UNLV Retrospective Theses & Dissertations

This quasi-experimental, mixed methods study investigated whether students writing development and proficiency, in combination with teacher-led instruction, are significantly affected by the use of an automated essay scoring (AES) system. The ninth grade standard and honors English students were divided into control and treatment groups at a large, urban high school. Student writing was examined for any changes in proficiency, measured by human- and AES-scored holistic measures. A developmental writing index was used to analyze the rate of change in pre- and post-essays. The AES system was further researched by comparing the treatment and control groups' trait score categories. Finally, …

Although strides recently have been made to facilitate the understanding of relational aggression and its consequences, one significant limitation has been the lack of research on long-term impact. Through a grounded theory approach, this study examines how resiliency behaviors exhibited by victims of relational aggression during their adolescent years aid in the development of trusting adult friendships.


Ayp Accountability Policy And Assessment Theory Conflicts, Randall S. Davies Jan 2008

Ayp Accountability Policy And Assessment Theory Conflicts, Randall S. Davies

Mid-Western Educational Researcher

A major objective of NCLB is to hold schools accountable for student achievement including closing the achievement gap and raising standards of student academic proficiency. While the majority of individuals support the underlying values of NCLB, not all agree its accountability policy is reasonable. The most problematic issue is the mandate that schools be held accountable to ensure all students perform at grade level when the methods used by states to determine grade level proficiency preclude the attainment of this standard. The unintended consequences of a policy that does not align theoretically with established educational best practice inevitably result in …


Sheltering Corporate Assets From Political Extraction, Lorenzo Caprio, Mara Faccio, John J. Mcconnell Jan 2008

Sheltering Corporate Assets From Political Extraction, Lorenzo Caprio, Mara Faccio, John J. Mcconnell

Purdue CIBER Working Papers

We hypothesize that firms structure their asset holdings so as to shelter assets from extraction by politicians and bureaucrats. Specifically, in countries where the threat of political extraction is higher, we hypothesize that firms will hold a lower fraction of their assets in liquid form. Consistent with this conjecture, using firm-level data from 109 countries, we find that, across countries, corporate holdings of cash and marketable securities are negatively correlated with measures of political corruption. Further, we find that annual investment in property, plant, equipment, and inventory plus dividends is positively correlated with the measures of corruption suggesting that owners …

Visualization Of Convection Patterns Near An Evaporating Meniscus Using Micro-Piv, Pramod Chamarthy, Hemanth Dhavaleswarapu, S V. Garimella, Jayathi Y. Murthy, Steven Wereley

CTRC Research Publications

Experimental visualizations of the three dimensional (3D) convection patterns generated near an evaporating meniscus in horizontally oriented capillary tubes are presented. These patterns are caused due to the differential evaporation along the meniscus. In this study, transparent capillary tubes with refractive index close to that of the evaporating liquid were used to minimize refraction effects and obtain velocity vectors near the walls. Polystyrene fluorescent particles of 0.5 lm diameter suspended in methanol were used to make the measure- ments in tubes of 75, 200 and 400 lm diameter. For the 75 lm tube, gravity was observed to have no effect …

Evolutionary Methodology For Optimization Of Image Transforms Subject To Quantization Noise, Michael Ray Peterson

Browse all Theses and Dissertations

Lossy image compression algorithms sacrifice perfect imagereconstruction in favor of decreased storage requirements. Modelossy compression schemes, such as JPEG2000, rely upon the discrete wavelet transform (DWT) to achieve high levels of compression while minimizing the loss of information for image reconstruction. Some compression applications require higher levels of compression than those achieved through application of the DWT and entropy coding. In such lossy systems, quantization provides high compression rates at the cost of increased distortion. Unfortunately, as the amount of quantization increases, the performance of the DWT for accurate image reconstruction deteriorates. Previous research demonstrates that a genetic algorithm can …


Mechanisms Of Nickel-Based Coatings For Fretting Wear Mitigation Of Ti6al4v Interfaces, Carl H. Hager Jr. Jan 2008

Mechanisms Of Nickel-Based Coatings For Fretting Wear Mitigation Of Ti6al4v Interfaces, Carl H. Hager Jr.

Browse all Theses and Dissertations

Fretting wear is an accumulation of damage that occurs at component interfaces that are subjected to high contact stresses coupled with low amplitude oscillation. The key to fretting wear reduction in metallic contacts is the mitigation of galling at the interface, followed by the control of debris production and the rheology of active wear debris. Once the thin surface species of the metallic interfaces is dispersed, adhesion between the contacting nascent surfaces causes the inception of severe surface deformation and material transfer or removal. This is extremely apparent in the fretting wear of aerospace materials such as titanium alloy and …
