Application Of Manova And Mahalanobis Distance In Quality Control, Mahua. Seth Jan 1997

Application Of Manova And Mahalanobis Distance In Quality Control, Mahua. Seth

Electronic Theses and Dissertations 1990 - 1999

Many quality control problems are multivariate in nature since multiple process or product variables are measured and monitored in modern industry. Occasionally a multiple population, multi-variable scenario is encountered in parallel line manufacturing system. This work deals with the analysis of such system using multivariate techniques such as Canonical Analysis, MANOVA and Mahalanobis Distance. Using such techniques, the significant differences between the populations and the magnitude and directions of the variations within and between the populations were determined. Also, elimination/reduction of such variations using multivariate techniques led to a drastic improvement of the production system. A methodology for application of …

Adolescent Relationships And Their Contributions To Social And Academic Competence, Vonda Dionne Jones-Hudson

Electronic Theses and Dissertations 1990 - 1999

School success is associated with parent- and peer-relationships. To study the connection between these alliances and school success, 30 African-American and 30 European-American 6th graders were given the Relationship Closeness Inventory, Network of Relationships Inventory, Self-Perception Profile, Revised Class Play, and Youth Self-Report. A parent and best friend also completed surveys. Results show parent and peer support relates to the social competence of youth. Father support is associated with female aggressive-disruptive behavior, and best friend support is associated with sensitive-isolated behavior in boys. African-American parents do more social events with their children than European-American parents do with their children. European-Americans …

Applications Of Evolutionary Algorithms In Mechanical Engineering, Kevin M. Nelson Jan 1997

Applications Of Evolutionary Algorithms In Mechanical Engineering, Kevin M. Nelson

Electronic Theses and Dissertations 1990 - 1999

Many complex engineering designs have conflicting requirements that must be compromised to effect a successful product. Traditionally, the engineering approach breaks up the complex problem into smaller sub-components in known areas of study. Tradeoffs occur between the conflicting requirements and a sub-optimal design results. A new computational approach based on the evolutionary processes observed in nature is explored in this dissertation. Evolutionary algorithms provide methods to solve complex engineering problems by optimizing the entire system, rather than sub-components of the system. Three standard forms of evolutionary algorithms have been developed: evolutionary programming, genetic algorithms and evolution strategies. Mathematical and algorithmic …

Balanced Hypercube: A Versatile Cube-Based Multicomputer System, Ke. Huang Jan 1997

Balanced Hypercube: A Versatile Cube-Based Multicomputer System, Ke. Huang

Electronic Theses and Dissertations 1990 - 1999

We propose the balanced hypercube (BH), which is a variant of the standard hypercube (Q), as a multicomputer topological structure. An n-dimensional balanced hypercube BHn has the same desirable topological properties of the 2n-dimensional standard hypercube Q2n such as size (2^2n nodes and n2^2n edges), regularity and symmetry, connectivity (2n node-disjoint pathes between any pair of nodes), and diameter (2n when n = 1 or n is even). Moreover, BHn has smaller diameter (2n-1) than Qn's (2n) when n is odd other than 1. In addition, BHn is load balanced, i.e., for every node v of BHn, there exists another …

Correctness Analysis Of Cache Conherence Protocols Using Petri Nets, Ahmed Kamal Hassan Jan 1997

Correctness Analysis Of Cache Conherence Protocols Using Petri Nets, Ahmed Kamal Hassan

Electronic Theses and Dissertations 1990 - 1999

The use of cache memories in multiprocessor systems increases the overall systems performance. Caches reduce the amount of network traffic and provide a solution to the memory contention problem. However, caches introduce memory consistency problems. The existence of multiple cache copies of a memory block will result in an inconsistent view of memory if one processor changes a value in its associated cache. Cache coherence protocols are algorithms designed in software or hardware to maintain memory consistency. With the increased complexity of some of the more recent protocols, testing for the correctness of these protocols becomes an issue that requires …

Domestic Sybil: Feminist Concerns In P. L. Travers's "Mary Poppins" And "Mary Poppins Comes Back", Donna M. Revtai Jan 1997

Domestic Sybil: Feminist Concerns In P. L. Travers's "Mary Poppins" And "Mary Poppins Comes Back", Donna M. Revtai

Electronic Theses and Dissertations 1990 - 1999

Certain elements in P. L. Travers's Mary Poppins (1934) and Mary Poppins Comes Back (1935) depict concerns that feminist critics deem important, such as mother figures, females as artists, women who exert power or lack it, female self-concepts, matrilineal connections and mother/child relationships. Travers sometimes treats these subjects ambiguously or ambivalently, but her attention to them indicates a riveting interest at the time. Her creative process whereby she projected childhood fantasies onto her ideal nanny, Mary Poppins, with whom she identified herself and others, relates to a feminine psychology. Travers's cyclic and web-like plots may link her to feminist aesthetics …

Echoes Of Wordsworth And Coleridge Resound In "The Accidental Tourist", Susan Clare Finger Jan 1997

Echoes Of Wordsworth And Coleridge Resound In "The Accidental Tourist", Susan Clare Finger

Electronic Theses and Dissertations 1990 - 1999

Anne Tyler, who lived a "Romantic" childhood in mountain-terrained communes of North Carolina, borrowed ideas from Wordsworth and Coleridge for her 1985 novel The Accidental Tourist. Reflections of these Romantic poets are seen primarily in images but are also seen in Tyler's simple writing style. Macon Leary, the protagonist of the novel, is a wandering writer who loves the English language, but struggles to communicate his feelings verbally, a reflection of Romantic ideology. Other motifs include home as a place abandoned as well as a refuge for the mind and body; the destructive and renewing powers of the city; physical …

Diversity Techniques In Direct Sequence Code Division Multiple Access Communication Systems, Okechukwu Clark Ugweje Jan 1997

Diversity Techniques In Direct Sequence Code Division Multiple Access Communication Systems, Okechukwu Clark Ugweje

Electronic Theses and Dissertations 1990 - 1999

This dissertation investigates the performance of different space diversity combining techniques for the wireless mobile communication systems employing Direct Sequence-Code Division Multiple Access (DS-CDMA). It covers two research topics, all falling under the umbrella of diversity combining techniques. The first part deals with diversity reception of wideband DS-CDMA signals in which the diversity branches experience some correlation. This analysis is performed without the usual assumption that diversity branches are independent and hence uncorrelated. In this case, the analysis is limited to the conventional diversity techniques such as maximal ratio combining, equal gain combining and selection diversity. In particular, the effect …

Effect Of Feeding On Repopulation Of The Sea Anemone Aiptasia Pallida By Symbiotic Dinoflagellates (Zooxanthellae), Randa N. Flinn

Electronic Theses and Dissertations 1990 - 1999

Many marine organisms possess endosymbiotic dinoflagellates called zooxanthellae. Bleaching is the loss of zooxanthellae, but bleached hosts can be repopulated. Little is known about how repopulation is controlled. The sea anemone Aiptasia pallida was used to study the effects of feeding on repopulation. Two groups of aposymbiotic anemones were reinfected with algae from symbiotic clones. One group was fed and the other starved, and counts of algae within each anemone were made at 3 day intervals for 6 weeks. The experiment was repeated, and results showed that the rate of algal growth did not differ between fed and starved groups. …

Effect Of Message Latency In An Atm Network On Signal Processing, Ralph Lawrence Weber Jan 1997

Effect Of Message Latency In An Atm Network On Signal Processing, Ralph Lawrence Weber

Electronic Theses and Dissertations 1990 - 1999

Signal processing requires a steady flow of sampled data to be able to properly manipulate the signal to get the desired output. By using Asynchronous Transfer Mode (ATM) networks, it is possible to divide signal processing amongst a number of stations where each station can be specialized to a single function. Unfortunately, most commercially available ATM Network Interface Cards (NIC) only support message mode ATM Adaptation Layer 5 (AAL5) which is unsuitable to signal processing due to the delays of having to wait for an entire message to be formed prior to sending. It is shown that by using an …
