A Study Of Distributed Clustering Of Vector Time Series On The Grid By Task Farming, Arun B. Nayar Jan 2005

A Study Of Distributed Clustering Of Vector Time Series On The Grid By Task Farming, Arun B. Nayar

LSU Master's Theses

Traditional data mining methods were limited by availability of computing resources like network bandwidth, storage space and processing power. These algorithms were developed to work around this problem by looking at a small cross-section of the whole data available. However since a major chunk of the data is kept out, the predictions were generally inaccurate and missed out on significant features that was part of the data. Today with resources growing at almost the same pace as data, it is possible to rethink mining algorithms to work on distributed resources and essentially distributed data. Distributed data mining thus holds great …

Cognitive Memory Effects On Non-Linear Video-Based Learning, Katherine Renee Comeaux Jan 2005

Cognitive Memory Effects On Non-Linear Video-Based Learning, Katherine Renee Comeaux

LSU Master's Theses

During an informative learning process, information, material, facts and ideas are typically conveyed in a linear arrangement. Individuals are frequently distracted during this process with their attention being diverted to an interruption (Internet, phone call, etc). When presented with any new information, the mind evolves through problem solving and evaluation procedures. The way in which that information is processed and perceived depends on: (a) original presentation (b) examination of material and (c) an individualistic measurement of success. However, when faced with an interruption, the person is forced to deal with non-linear arrangement of information. This research investigates nonlinear presentation or …

Musculoskeletal Disorders In Dentistry, Frank Maurice Pitts Jan 2005

Musculoskeletal Disorders In Dentistry, Frank Maurice Pitts

LSU Master's Theses

Because of the common occurrence of pain experienced by dental professionals during the course of a workday and throughout their career, an epidemiological and a field study were performed in an effort to contribute to the prevention of musculoskeletal disorders in dentistry. The aim of the thesis is two fold: to assess the perception of occupational pain and discomfort felt by dentists through a perception based survey and to assess the muscle behavior of dentists during isotonic postures while performing various dental procedures on their first and last patients in a given work day. One hundred (100) dentists participated in …

An Application Of Parallel Computation To Collaborative Optimization, Shahab Nayyer Jan 2005

An Application Of Parallel Computation To Collaborative Optimization, Shahab Nayyer

LSU Master's Theses

Multidisciplinary Design Optimization (MDO) has evolved as a discipline which provides a body of methods and techniques to assist engineers in solving large scale design problems. There are many frameworks for formulating MDO problems. These frameworks can be broadly classified as single-level or bi-level formulations. Collaborative Optimization (CO) is one of the popular bi-level formulations to solve an MDO problem. There are numerous design optimization problems which are highly CPU time intensive and require a long simulation time. With the advent of cheaper and faster available PC’s, distributed parallel computer clusters have become very popular. These clusters provide large computing …

Multi-National Project Team Communications And Cultural Influences, Morgan E. Henrie Jan 2005

Multi-National Project Team Communications And Cultural Influences, Morgan E. Henrie

Engineering Management & Systems Engineering Theses & Dissertations

This exploratory case study dissertation examined multinational project teams' communication satisfaction as influenced by the project team's cultural attribute of power distance. Utilizing a exploratory case study, semi-guided interview research approach, ordinal scale data and open-ended contextual based question responses was obtained. This data was gathered from United States---Russia and Canada---Angola multi-national, complex, high technology oil transportation project teams. Triangulation data gathering techniques were utilized to obtain empirical data from multiple sources of data and multiple data types. Subsequent data analyses combined descriptive statistical analysis, graphical analysis, cluster analysis, and content analysis techniques to derive a theoretical construct of multi-national …

Complex System Contextual Framework (Cscf): A Grounded-Theory Construction For The Articulation Of System Context In Addressing Complex Systems Problems, W. B. Max Crownover Jan 2005

Complex System Contextual Framework (Cscf): A Grounded-Theory Construction For The Articulation Of System Context In Addressing Complex Systems Problems, W. B. Max Crownover

Engineering Management & Systems Engineering Theses & Dissertations

The complexity of problems facing society continues to grow, and decision-makers and problem-solvers are finding many of today's emerging problems to be beyond their capability to adequately address. There is agreement in the literature that problems of this nature are complex system problems, inextricably linked to some highly complex system of systems. Establishing a clear understanding of the specific complex system context is fundamental to the process of understanding and analyzing complex systems and complex system problems across all of the different systems-based disciplines. While complex system context is widely referred to in systems literature, there is no clear characterization …
