Optimization Of Operating Parameters For Minimum Mechanical Specific Energy In Drilling, Todd Robert Hamrick
Optimization Of Operating Parameters For Minimum Mechanical Specific Energy In Drilling, Todd Robert Hamrick
Graduate Theses, Dissertations, and Problem Reports
Efficiency in drilling is measured by Mechanical Specific Energy (MSE). MSE is the measure of the amount of energy input required to remove a unit volume of rock, expressed in units of energy input divided by volume removed. It can be expressed mathematically in terms of controllable parameters; Weight on Bit, Torque, Rate of Penetration, and RPM. It is well documented that minimizing MSE by optimizing controllable factors results in maximum Rate of Penetration. Current methods for computing MSE make it possible to minimize MSE in the field only through a trial-and-error process. This work makes it possible to compute …

Significance Of Design Context And Rationale In Long Term Retention Of Data, Samrat Sarovar
Graduate Theses, Dissertations, and Problem Reports
Mechanical Engineering Design is said to be both; science and art. In the process of designing mechanical systems or components, decisions are typically made to conceptualize, synthesize, and ultimately define the final configuration of a mechanical system or component, through an iterative process that involves design, analysis, performance assessment and experimental validation tasks. In the process, a plethora of engineering methods, analytical tools and technical data are used to yield a final design. Typically, the final design is documented, but in most cases, much (if not all) rationale that led to the final configuration is left undocumented and eventually lost. …
Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich
Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich
Graduate Theses, Dissertations, and Problem Reports
Despite the vast processing power of modern GPUs, rendering terrain geometry at sufficient frame rates is still a very difficult task. This is mainly due to the large terrain data that must be managed, displayed and modified at high frame rates. While traditional level-of-detail algorithms for terrain utilize most of the CPU and a fraction of the GPU, our algorithm exploits the parallel processing capabilities of the GPU. We represent the terrain geometry as a set of geometry images which allows us to apply image processing techniques to preserve terrain features during level-of-detail transitions and to render terrain that has …

Data Recovery From Magnetic Media Using Magnetic Force Microscopy, Terry R. Ferrett
Data Recovery From Magnetic Media Using Magnetic Force Microscopy, Terry R. Ferrett
Graduate Theses, Dissertations, and Problem Reports
Magnetic tapes are widely used to store voice and other data. Due to the effect of hysteresis, modification of the magnetization pattern written to a tape by overwriting, erasing, or physical damage leaves remanent information about the previous magnetization state that can not be discerned by standard audio playback devices. Recently, a high resolution microscopy technique known as magnetoresistive microscopy was used by Pappas et al. in an attempt to recover data from audio tapes which were physically damaged. However, the device, while having a higher resolution than tape playback heads, still averages over entire audio track widths when collecting …

The Evolving Perception Of Charles Ives And His Music, Hsiang-Chi Liao
The Evolving Perception Of Charles Ives And His Music, Hsiang-Chi Liao
Graduate Theses, Dissertations, and Problem Reports
When Charles Ives's music began to appear in performances and publications in the 1920s, his admirers often regarded him as an American experimentalist who had created radically new kinds of music that was independent from the European musical tradition. This outlook characterized much of what was written on Ives before the 1980s. At that time, a different picture of Ives gradually began to emerge. It argues that in fact, Ives's music owes as much to the European classical tradition as to American vernacular traditions. Scholars began to reconsider Ives's place in music history and stress his debt to the European …
