Data Mining-Driven Approahces For Process Monitoring And Diagnosis, Thuntee Sukchotrat Jan 2008

Data Mining-Driven Approahces For Process Monitoring And Diagnosis, Thuntee Sukchotrat

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

The objective of this dissertation is to develop a new set of efficient process monitoring and diagnostic tools through their integration with data mining algorithms. Statistical process control (SPC) is one of the most widely used techniques for quality control. Although traditional SPC tools are effective in simple manufacturing processes that generate a small volume of independent data, these tools falter when confronted by the large streams of complex and correlated data found in modern manufacturing systems. As the limitations of SPC methodology become increasingly obvious in the face of ever more complex manufacturing processes, data mining, because of its …

Temporal Potential Function Approach For Path Planning In Dynamic Environments, Vamsikrishna Gopikrishna Jan 2008

Temporal Potential Function Approach For Path Planning In Dynamic Environments, Vamsikrishna Gopikrishna

Computer Science and Engineering Theses - Archive

A Dynamic environment is one in which either the obstacles or the goal or both are in motion. In most of the current research, robots attempting to navigate in dynamic environments use reactive systems. Although reactive systems have the advantage of fast execution and low overheads, the tradeoff is in performance in terms of the path optimality. Often, the robot ends up tracking the goal, thus following the path taken by the goal, and deviates from this strategy only to avoid a collision with an obstacle it may encounter. In a path planner, the path from the start to the …

Adapting Harmonic Function Path Planning: To Reflect User Motion Preferences, Giles John D'Silva Jan 2008

Adapting Harmonic Function Path Planning: To Reflect User Motion Preferences, Giles John D'Silva

Computer Science and Engineering Theses - Archive

Every human in the real world has a unique motion preference while moving to achieve a given task. These preferences could be expressed by moving in a straight line, following the wall along a corridor, avoiding sharp turns, preferring hard flat surfaces over damp uneven surfaces, choosing the shortest path to the goal or by giving a high priority towards safety by maintaining a definite distance from obstacles. To automatically incorporate user preferences into motion planning we could extract the trajectories taken by the user to achieve a task in a given local vironment and attempt to use them in …

Texas And The Good Roads Movement: 1895 To 1948, Karl E. Wallace Jan 2008

Texas And The Good Roads Movement: 1895 To 1948, Karl E. Wallace

History Theses - Archive

The Good Roads Movement in America grew directly out of concerns over the debilitating effects of rural isolation. However, as each state faced its own unique challenges to the building and maintenance of roads, the early movement reflected broad regional differences. In Texas, the breadth of its borders, the scattered and uneven distribution of its population, and numerous historically rooted prejudices towards the proper role of government defined its differences. Even after the need for good roads had become undeniable, and roads advocacy was galvanized into a national movement, the social and political divisions that existed within Texas would prevent …

Not My Father's Game: Immigration, Major League Baseball And The Dominican Republic, Marylyn Koble Jan 2008

Not My Father's Game: Immigration, Major League Baseball And The Dominican Republic, Marylyn Koble

Sociology & Anthropology Theses - Archive

Since the 1980's the number of Latino players, specifically, Dominicans, on major and minor league baseball teams has increased significantly. This demographic shift is due, in large part, to Major League Baseball (MLB) teams actively recruiting and developing Dominican players via the Dominican academy system. This thesis focuses on the process through which Dominican minor league baseball players are made into commodities by the global corporation of MLB. I examine the experiences of Dominican players as both baseball commodities and immigrants, comparing the challenges they face acculturating to American life with other Dominican immigrants in the North Texas area.

(Im)Politeness In Casual Conversations Among Female Mandarin Speakers: A Practice-Based Perspective, Hui-Yen Wang Jan 2008

(Im)Politeness In Casual Conversations Among Female Mandarin Speakers: A Practice-Based Perspective, Hui-Yen Wang

Linguistics & TESOL Dissertations - Archive

The fact that people have the choice to use different words and attitudes to convey messages of various significance has been attributed to politeness concerns. However, what constitutes politeness varies from culture to culture and person to person. Therefore, a universal definition for what politeness is does not seem plausible. Furthermore, using the term `politeness' to indicate the study of all kinds of linguistic behavior is problematic because `politeness' seems to exclude behavior that is inappropriate, aggressive or rude. To provide a more comprehensive account of politeness, this research draws upon the notion of "(im)politeness" (Watts, 2003) to account for …

Spectroscopy Is Applied Quantum Mechanics. Part 2: The Quantum Revolution, David W. Ball Jan 2008

Spectroscopy Is Applied Quantum Mechanics. Part 2: The Quantum Revolution, David W. Ball

Chemistry Faculty Publications

The article presents several theories relative to the nature of matter. The quantum theory of German theoretical physicist Max Planck proposes that the energy of a vibrating atom was related to its frequency. Albert Einstein's quantum theory of light hypothesizes that light itself had an energy that was directly proportional to its frequency. Danish physicist Niels Bohr develops an equation that could help explain the lines that appeared in the spectrum of the hydrogen atom.
