Dynamic Storage Allocation Using Simon's Model Of Information Usage., Rachelle Folse Cope Jan 1996

Dynamic Storage Allocation Using Simon's Model Of Information Usage., Rachelle Folse Cope

LSU Historical Dissertations and Theses

In today's rapidly changing field of Management Information Systems (MIS) one problem faced by organizations is the consumption of storage capacity due to the growing base of software assets. Research has shown that very few firms effectively monitor program usage. Storage management issues arise due to the fact that many of the programs occupying valuable storage space are used infrequently. In this dissertation, we apply Simon's model of information usage in order to model the dynamic behavior of program usage. This methodology enables organizations to identify the changing usage frequencies of software assets. We propose a classification scheme which MIS …

Fluorescence Polarization Studies: A Global View Of Molecular Photoionization Dynamics Over An Extended Energy Range., Romith Ranjan Das Jan 1996

Fluorescence Polarization Studies: A Global View Of Molecular Photoionization Dynamics Over An Extended Energy Range., Romith Ranjan Das

LSU Historical Dissertations and Theses

The experimental technique of measuring the degree of polarization of the fluorescence from electronically excited molecular ions is used to determine the alignment of N$\sb2$, CO and N$\sb2$O photoions over an extended range of excitation energy. The polarization of $\rm CO\sp+(B\sp2\Sigma\sp+\to\ X\sp2\Sigma\sp+),\ N\sb2\sp+(B\sp2\Sigma\sb{u}\sp+\ \to \ X\sp2\Sigma\sb{g}\sp+)$, and $\rm N\sb2O\sp+\ (A\sp2\Sigma\sp+\ \to\ X\sp2\Pi)$ fluorescence over a 200 eV photon energy range is used to interpret the oscillator strength distributions for normally unresolved degenerate ionization channels. The results show the influence of a CO $4\sigma\to k\sigma$ shape resonance clearly, and agreement between theory and experiment is excellent. The N$\sb2$O experimental results indicate …

The Study Of High Energy Heavy Nucleus Interactions In Nuclear Emulsion Chambers Using Digital Image Processing., Philip Vern Deines-Jones Jan 1996

The Study Of High Energy Heavy Nucleus Interactions In Nuclear Emulsion Chambers Using Digital Image Processing., Philip Vern Deines-Jones

LSU Historical Dissertations and Theses

Nuclear emulsion chambers with lead targets have been exposed to a 158 GeV per nucleon beam of $\sp{208}$pb nuclei, by far the heaviest ion accelerated to such a high energy to date. These interactions frequently produce more than 1000 charged particles. In order to measure multiplicities and secondary particle trajectories in these extremely large events, an automatic CCD-based microscope system has been developed to analyze images, count secondary tracks, measure their trajectories, and estimate their charge. Based on the analysis of 40 high-multiplicity Pb-Pb events measured using this system, we assess the degree to which these interactions can be described …

Cognitive Differences And Their Predictive Ability On Reading Performance In Skilled And Unskilled Readers., Mary Elizabeth Carter Jan 1996

Cognitive Differences And Their Predictive Ability On Reading Performance In Skilled And Unskilled Readers., Mary Elizabeth Carter

LSU Historical Dissertations and Theses

The present study examined the relationships among short-term memory, working memory, phonological awareness, and reading performance as measured by an informal reading inventory. Relationships between and among the tasks, their predictive importance with regard to word recognition, accuracy, fluency, and comprehension, and their ability to discriminate among groups of readers were investigated. A battery of tests comprising 14 cognitive variables and 24 reading variables was individually administered to 105 fourth and fifth grade normally achieving readers, unidentified unskilled readers, and school identified unskilled readers. Results revealed that working memory, phonological awareness, and syntactic awareness tasks were significantly intercorrelated among themselves, …

Applications Of Grobner Bases To Linear Codes., Jeanne Fitzgerald Jan 1996

Applications Of Grobner Bases To Linear Codes., Jeanne Fitzgerald

LSU Historical Dissertations and Theses

Put $A={\bf F}\sb{q}\lbrack x\sb1,\...,x\sb{s}\rbrack,$ and let I be an ideal of A. Let $P\sb1,\...,P\sb{n}$ be all the ${\bf F}\sb{q}$-rational points of $V(I)$. Define a map $\varphi:A/I\to{\bf F}\sbsp{q}{n}$ by $\varphi(\tilde f)=(f(P\sb1),\...,f(P\sb{n})),$ where f is any preimage of $\tilde f$ under the canonical map from A to $A/I.$ Let $\{\tilde f\sb{i}\vert i\in {\bf N}\}$ be a basis of $A/I$ as an ${\bf F}\sb{q}$-vector space. Define the affine variety code C and its dual $C\sp\perp$ by$$C=\varphi(\langle\tilde f\sb1,\...,\tilde f\sb{m}\rangle);$$C$\sp\perp$ is the orthogonal complement of C with respect to the usual inner product in ${\bf F}\sbsp{q}{n}$. We show that any linear code can be expressed …

The Role Of Environmental Attitudes In Incentive-Based Environmental Management: The Case Of The Wetland Reserve Program., Assane Diagne Jan 1996

The Role Of Environmental Attitudes In Incentive-Based Environmental Management: The Case Of The Wetland Reserve Program., Assane Diagne

LSU Historical Dissertations and Theses

Environmental policy in the United States is increasingly relying on incentive-based mechanisms (IBM). Incentive-based mechanisms, are voluntary environmental management instruments based on free market environmentalism, a framework that attempts to harness market forces. A multi-disciplinary approach was developed to evaluate participation decisions in IBM's such as the Wetland Reserve Program. This approach extended the traditional utility maximization approach to choice behavior by including alternative measures of environmental attitudes based on the theory of reasoned action or the New Environmental Paradigm. The addition of these psychological constructs conceptually improved the utility maximization by allowing the consideration of well established determinants of …

The Effects Of Ama Contributions In The United States Senate: An Analysis Of Roll Call Votes, 1979--1992., Karen Gutermuth Jan 1996

The Effects Of Ama Contributions In The United States Senate: An Analysis Of Roll Call Votes, 1979--1992., Karen Gutermuth

LSU Historical Dissertations and Theses

Based on the economic theory of regulation, our model portrays U.S. senators as utility-maximizing agents and the American Medical Association (AMA) as a rational contributor. We use contributions from the AMA's political arm, the American Political Action Committee (AMPAC), and roll call votes in the U.S. Senate from 1979-1992 to test for AMPAC contributions effects, to test the hypothesis that the AMA "rewards" senators for their voting behavior, and to determine the role of issue specificity. We use pooled, cross-sectional data in a simultaneous Probit-Tobit-Generalized Least Squares framework and extend the traditional analyses by examining alternative timing specifications, election year …

Homework Performance In Middle And High School Students: A Comparison Of The Effects Of Goal Setting With And Without Contingent Rewards., Alice L. Kahle Jan 1996

Homework Performance In Middle And High School Students: A Comparison Of The Effects Of Goal Setting With And Without Contingent Rewards., Alice L. Kahle

LSU Historical Dissertations and Theses

Participation in homework has important academic benefits for students. In addition, parents and teachers expect that completion of homework assignments will help students develop independent study skills. Unfortunately, homework problems are common and a significant number of middle school and high school students fail to complete many homework assignments. Goal setting is a procedure that has been applied to homework and targets academic productivity directly. In this study, the efficacy of a self-managed goal setting procedure for improving the homework performance of middle and high school students was evaluated. A combination multiple baseline and alternating treatments design was utilized to …

"Only A Girl": Christine Frederick, Efficiency, Consumerism, And Women's Sphere., Janice Williams Rutherford Jan 1996

"Only A Girl": Christine Frederick, Efficiency, Consumerism, And Women's Sphere., Janice Williams Rutherford

LSU Historical Dissertations and Theses

Christine Frederick was a home efficiency expert who worked out of her home experiment station, Applecroft, in Greenlawn, New York, from 1910 to 1939. She advocated the application of scientific management, technology, and consumer awareness to homemaking. Frederick came of age during a time when feminism was opening a window of opportunity for middle-class, educated, white women. By the time she graduated from Northwestern University, the nineteenth-century doctrine of separate spheres was being challenged. Charlotte Perkins Gilman's critique of the single-family home had been published, the woman suffrage campaign would gain new momentum within the next few years, and women …

Postexercise Hypotension (Peh) In The Dog: Possible Role Of Immune System Cytokines., Gerald Dwayne Thompson Jan 1996

Postexercise Hypotension (Peh) In The Dog: Possible Role Of Immune System Cytokines., Gerald Dwayne Thompson

LSU Historical Dissertations and Theses

This study investigated postexercise hypotension (PEH) in five normotensive dogs testing these hypotheses: (1) PEH is present in the dog model; (2) high intensity exercise of 85% HR$\rm\sb{max}$ as compared to moderate intensity exercise of 60% HR$\rm\sb{max}$ induces a greater PEH; and (3) IL-1 and its activation of PGE$\sb2$ are associated with PEH. In experiment I, it was found that 85% HR$\rm\sb{max}$ exercise decreased systolic blood pressure (SBP) and mean arterial blood pressure (MABP) at 30 and 60 minutes postexercise (p $<$ 0.05). Both IL-1 and PGE$\sb2$ increased immediately following intense exercise, although temporal patterns were dissimilar. During non-exercise infusion of ibuprofen or dexamethasone (experiment II), blood pressure was not affected, but ibuprofen led to an overall inhibition of PGE$\sb2$. However, dexamethasone infusion led to a significant increase in PGE$\sb2$ at 180 and 210 minutes postinfusion. In experiment IIIA, after intense exercise following ibuprofen or saline infusion, PGE$\sb2$ increased at 120 to 180 minutes postexercise. Similar results were noted after exercise during dexamethasone treatment (experiment IIIB). In experiment IIIA & B, neither ibuprofen nor dexamethasone significantly affected PEH, although non-significant reductions in PEH was observed in dexamethasone treated animals. However, PGE$\sb2$ significantly increased after exercise at time points when PEH was not observed. These data indicate that (1) the intensity of exercise may have an effect on PEH, (2) there is partial support for the involvement of IL-1 and PGE$\sb2$ in PEH due to their immediate increase after exercise although a direct relationship was not observed, and (3) IL-1 still remains a possible mechanism responsible for PEH because of trends for attenuated PEH and PGE$\sb2$ responses following dexamethasone treatment.

Low Temperature Silicon Oxide And Fluorinated Silicon Oxide Films Prepared By Plasma-Enhanced Chemical Vapor Deposition Using Disilane As Silicon Precursor., Juho Song Jan 1996

Low Temperature Silicon Oxide And Fluorinated Silicon Oxide Films Prepared By Plasma-Enhanced Chemical Vapor Deposition Using Disilane As Silicon Precursor., Juho Song

LSU Historical Dissertations and Theses

The deposition and characterization of the silicon oxide and fluorinated silicon oxide films, as interlevel dielectrics in microelectronics devices, prepared by plasma enhanced chemical vapor deposition at low substrate temperature using $\rm Si\sb2H\sb6$ as silicon precursor are studied. The film deposition is limited by the mass transport regime, resulting in nearly temperature independent deposition rate. The characteristics for the silicon oxide films deposited at 120$\sp\circ$C show that the film etch rate is comparable to that obtained by TEOS-based PECVD at 400$\sp\circ$C and the leakage current is comparable to that of the films deposited at 350$\sp\circ$C with conventional SiH$\sb4$ precursor. It …

The Effects Of Industry Deregulation On The Stock Market Responses To Earnings Announcements., Wah Poon Jan 1996

The Effects Of Industry Deregulation On The Stock Market Responses To Earnings Announcements., Wah Poon

LSU Historical Dissertations and Theses

Many sectors of the United States economy have experienced deregulation during the 1970s and 1980s. This study examines how deregulation affects the informativeness of accounting earnings of firms in deregulation industries. In this study, the informativeness of accounting earnings is measured by the earnings response coefficient (ERC, the slope coefficient in the regression of abnormal stock returns on unexpected accounting earnings). The effects of deregulation on ERCs are examined by (1) comparing ERCs before deregulation to those after deregulation to determine the changes in the magnitude of ERCs due to deregulation, (2) investigating the time series of ERCs after deregulation …

"Engineered Enjoyment": Technology, Capitalism, And The Female Body In Film., Catherine Williamson Jan 1996

"Engineered Enjoyment": Technology, Capitalism, And The Female Body In Film., Catherine Williamson

LSU Historical Dissertations and Theses

This dissertation explores the link between technology, capitalism, and the female body in 20th century cinema. It argues that commodified pleasure, or "engineered enjoyment," is always produced by establishing technological control over the female body. The scope of this dissertation is limited to films produced during the post-World War II era. In Chapter One I define "engineered enjoyment" and show how film is the prototypical example of such. In Chapter Two I examine how the cinematic apparatus works as a pleasure-producing system and explore what happens when that system breaks down, as in the 1947 film Lady in the Lake. …

The Association Between Chronic Aerobic Activity And Heart Rate Variability In Patients With Coronary Artery Disease., Robert Howard Wood Jan 1996

The Association Between Chronic Aerobic Activity And Heart Rate Variability In Patients With Coronary Artery Disease., Robert Howard Wood

LSU Historical Dissertations and Theses

Poor heart rate variability (HRV) among patients with coronary artery disease (CAD) is predictive of future incidence of sudden arrhythmic and all-cause death. Furthermore, mental stress appears to further depress HRV in these patients. Chronic aerobic activity level appears to be positively related to HRV among the general population; however, the extent to which this relationship exists among patients with CAD is not clear. Therefore, this study investigated the association between level of chronic aerobic activity and HRV among CAD patients during conditions of paced respiratory control and during the Stroop Color-Word Conflict Test (CWCT). CAD patients were assigned to …

Famine, Plague, And Greed: Socio-Historical Factors Affecting The Development Of The Middle English Dialect Of London., George Vincent Yonek Jan 1996

Famine, Plague, And Greed: Socio-Historical Factors Affecting The Development Of The Middle English Dialect Of London., George Vincent Yonek

LSU Historical Dissertations and Theses

A significant factor in the rise of Standard English was the importance of London as a center of commerce and government, yet the foundation for Modern Standard English is not derived from the Southern dialects, which heavily influenced London in the late Old English and early Middle English period. The variety of English we speak and write today is derived mainly from the East Midland dialect and, to a lesser extent, the North in late Middle English. The purpose of this thesis is to explore the socio-historical causes behind this change in the distribution of features of the London dialect. …

Artificial Grammar Learning In A Dual Task Paradigm., Barbara Cochran Jan 1996

Artificial Grammar Learning In A Dual Task Paradigm., Barbara Cochran

LSU Historical Dissertations and Theses

A series of experiments explored the effects of performing concurrent secondary tasks on learning letter strings created with a finite state artificial grammar. Experiments 1-2 compared a task which disrupted organized encoding to a task which simply required holding information in memory while encoding strings, as well as to two control tasks. Participants performing the disruptive task were worse at judging the grammaticality of test strings than were participants in the two single task control groups. Performance of the memory load group fell between the disruptive task group and the control groups, but was not significantly different from either. Experiments …

Wordsworth's Mother Tongue: Identification, Separation, And Recognition., Robert C. Hale Jan 1996

Wordsworth's Mother Tongue: Identification, Separation, And Recognition., Robert C. Hale

LSU Historical Dissertations and Theses

This psychoanalytic study complicates prevailing notions about William Wordsworth's representations of mothers. Wordsworth does not invariably conflate mothers with Nature or consistently construct women as silent objects of male quest. Rather, he explores a variety of mothers' voices, often associating them with language acquisition and poetic composition. In early work he acknowledges mothers' significance directly and creates more vocal mothers, while in later work and revisions he often conceals mothers' significance and depicts more object-like mothers. In the 1805 version of book two of The Prelude, Wordsworth recalls himself as a "blessed babe" who recognizes his mother as a separate …

Gender And Spousal Violence: A Test Of Social Control And Resource Theories., Deborah Marie Hanrahan Jan 1996

Gender And Spousal Violence: A Test Of Social Control And Resource Theories., Deborah Marie Hanrahan

LSU Historical Dissertations and Theses

This research provides an explanation of spousal violence that has previously been lacking in the family violence literature--a social control approach. This research tests the hypothesis that those with stronger bonds to society will be less likely to engage in spousal violence. Furthermore, this research will incorporate the role that family structures have in stratifying social control for males and females by testing power-control theory, which suggests that women from egalitarian households of origin will be more likely to commit wife-to-husband violence than those from patriarchal households. Conversely, men from egalitarian households should be less likely to commit husband-to-wife violence …

Biochemical And Biophysical Studies Of Wild-Type And Active-Site Mutants Of Human Adenosine Deaminase., Qing Zeng Jan 1996

Biochemical And Biophysical Studies Of Wild-Type And Active-Site Mutants Of Human Adenosine Deaminase., Qing Zeng

LSU Historical Dissertations and Theses

The focus of this work is structural and functional studies of wild-type and active-site mutants of human adenosine deaminase. Two active-site amino acids, Glu217 and His238, were previously substituted with alanine by site-directed mutagenesis. The Glu217Ala and His238Ala mutants showed little or no changes in Zn content and $\rm K\sb{m}$ value, yet dramatic loss of enzyme activity. Circular dichroism studies of the solution conformation of wild-type and mutant human adenosine deaminases indicate that 30 to 50% of $\alpha$-helical structure is lost in Glu217Ala and His238Ala, respectively, whereas $\beta$-sheet structure is fully retained. Inhibitor binding is measured by a fluorescent assay. …

A Case-Based Reasoning Approach To Bankruptcy Prediction Modeling., Stephanie Mattox Bryant Jan 1996

A Case-Based Reasoning Approach To Bankruptcy Prediction Modeling., Stephanie Mattox Bryant

LSU Historical Dissertations and Theses

This study examines the usefulness of an artificial intelligence method, case-based reasoning (CBR), in predicting corporate bankruptcy. Based on prior research, CBR is believed to be a viable method of predicting bankruptcy. Hypotheses are developed to test the usefulness of a CBR system and to compare the accuracy of such a system to the model considered to be the benchmark model in bankruptcy prediction, Ohlson's (1980) nine-factor logistic regression (logit) model. Sample data consisting of manufacturing and industrial firms is drawn from the Compustat database in a 20:1 ratio of nonbankrupt to bankrupt firms, consistent with Ohlson's (1980) proportions. Three …

Women Who Lead High Schools: A Missing Element In Leadership Theory., Kristy Brock Hebert Jan 1996

Women Who Lead High Schools: A Missing Element In Leadership Theory., Kristy Brock Hebert

LSU Historical Dissertations and Theses

I addressed the problem that leadership theory is lacking in regard to how women lead high schools. My primary purpose was to contribute to the limited literature that exists regarding the leadership practices of women who are high school principals. I explored the notion of a female culture of school leadership and situated that culture among quintessential theory dictated by organizational research. I conducted this study in two phases. In Phase One I reported the demographics of 44 female high school principals in Louisiana along with their self-reported values on 32 leadership characteristics. Most important to their leadership were: communication, …

Mechanism Of Nitrogen Fixation: Use Of Carbon Monoxide To Probe Nitrogenase Activity., Linda Margaret Cameron Jan 1996

Mechanism Of Nitrogen Fixation: Use Of Carbon Monoxide To Probe Nitrogenase Activity., Linda Margaret Cameron

LSU Historical Dissertations and Theses

The inhibitor CO was used to investigate the mechanism of Mo and V nitrogenase. While low pressures of CO enhanced, high pressures inhibited V nitrogenase-catalyzed C$\rm\sb2H\sb6$ formation. This is not the case for $\rm C\sb2H\sb4$ formation, where the rate of electron flux determined if CO acted as an enhancer or inhibitor. A two-site model is proposed, in which CO binding to one site enhances, and CO binding to both sites inhibits product formation. Replacement of CO(g) by Ar or $\rm C\sb2H\sb2$ resulted in correlated decay of hi-CO and development of lo-CO EPR signals, suggesting that the two signals arise from …

Synthesis Of Novel Amino Acids With Incorporation Into Peptides And Synthesis Of Peptides With Novel Aggregation States., Scott Michael Cowell Jan 1996

Synthesis Of Novel Amino Acids With Incorporation Into Peptides And Synthesis Of Peptides With Novel Aggregation States., Scott Michael Cowell

LSU Historical Dissertations and Theses

Peptides exhibit properties based on the amino acids present in the peptide and structure the peptide assumes in its environment. For example, peptides have been shown to be antimicrobial when they are amphipathic and in an $\alpha$-helical shape. The mechanism for this antimicrobial activity is subject to dispute. One theory states that the peptides work by forming a "pore" through the cell membrane which causes a depolarization of the membrane and the cell lysis because of osmosis. Another theory states that the peptides merely compromise the integrity of the membrane by solubilizing the membrane. In order for the "pore" theory …

Expression Of A Designed Cecropin Analog Gene Using A Baculovirus Vector., Kyusam Choi Jan 1996

Expression Of A Designed Cecropin Analog Gene Using A Baculovirus Vector., Kyusam Choi

LSU Historical Dissertations and Theses

Cecropins are basic, amphipathic peptides with antibacterial activity against many Gram-positive and Gram-negative bacteria. By retaining the positively charged, amphipathic characteristic of cecropin B, a cecropin analog S1, in which 54% of amino acid residues were substituted, was synthesized and shown to possess a broad spectrum of antimicrobial activity. To determine expression of the cecropin analog S1 in Sf9 cells, two gene constructs were designed, and inserted into Autographa californica nuclear polyhedrosis virus under the control of the polyhedrin promoter. One construct, pBS1, consisted of a gene encoding the analog peptide, so that the gene was intended for expression in …

An Examination Of The Effects Of Increased Response Requirement And Delay On Reinforcer Selection., Teresa Lynne George Jan 1996

An Examination Of The Effects Of Increased Response Requirement And Delay On Reinforcer Selection., Teresa Lynne George

LSU Historical Dissertations and Theses

This study examined the effect that increased response requirement, or effort, (Study 1) and delay to reinforcement (Study 2) have on reinforcer selection and response allocation. A reinforcer assessment using a token system was conducted within the classroom setting to determine high and low preference stimuli. The independent variable (effort or delay) was systematically manipulated for high preference stimuli. The results for eight participants indicated that increased levels of effort and delay independently influenced reinforcer preference and response allocation. The results revealed highly idiosyncratic responding to the different levels of the independent variables. The findings for increased response requirement are …

Plant Species Diversity And Community Structure In A Louisiana Coastal Marsh., Laura Gough Jan 1996

Plant Species Diversity And Community Structure In A Louisiana Coastal Marsh., Laura Gough

LSU Historical Dissertations and Theses

The factors that control plant species diversity have been examined by many researchers, but with little consensus as to the causes of diversity patterns. Plant diversity has been correlated with disturbance, competition, soil resources, and other variables. In the research presented here, I investigated the relationship between plant species richness and biomass, competition, nutrient enrichment, flooding, salinity, and herbivory in field studies in Louisiana coastal marshes. Biomass alone was a poor predictor of richness in two Louisiana marshes. When environmental variables (flooding, salinity, and soil fertility) were included with biomass in a multiple regression model, 82% of the variance in …

The Effects Of Performance Feedback On Treatment Integrity In School-Based Consultation., Kevin Michael Jones Jan 1996

The Effects Of Performance Feedback On Treatment Integrity In School-Based Consultation., Kevin Michael Jones

LSU Historical Dissertations and Theses

This study examined the relative effectiveness of traditional consultation, with and without performance feedback, on treatment integrity. Six teachers employed in a residential treatment community were responsible for treatment implementation. Treatment integrity was defined as the percentage of 2 min intervals during which contingent teacher attention for student on-task behavior was directly observed. Teacher and child behavior were monitored across baseline, traditional consultation, and consultation with performance feedback conditions in a multiple baseline design. In only one of six cases did mean levels of contingent teacher attention, following a Problem Identification Interview and Problem Analysis Interview (Bergan, 1977), exceed 35%. …

Adaptive Harmonic Blocking Compensators., Shih-Min Hsu Jan 1996

Adaptive Harmonic Blocking Compensators., Shih-Min Hsu

LSU Historical Dissertations and Theses

This dissertation explores a new method of adaptive compensation and harmonic suppression in distribution systems. The compensator under development and investigation integrates a harmonic blocking compensator (HBC) with an adaptive balancing compensator (ABC) resulting in an adaptive harmonic blocking compensator (AHBC). Such a compensator can be used for compensating reactive power, for symmetrizing supply currents, for protecting the distribution system against load generated current harmonics and, consequently, the voltage harmonic distortion caused by non-linear loads. Harmonic blocking compensators are designed for compensating fixed loads, and they are not adaptive devices, while the adaptive capability of compensators is becoming more and …

Design And Analysis Of Reduced-Connection Multiple Bus Systems: A Probabilistic Approach., Najmul Karim Jan 1996

Design And Analysis Of Reduced-Connection Multiple Bus Systems: A Probabilistic Approach., Najmul Karim

LSU Historical Dissertations and Theses

In the dissertation we have proposed the first systematic and formal approach to reduce connectivity of general purpose multiple bus systems. The approach is based on a probabilistic technique. The hypothesis on which this dissertation is based stipulates that bus connectivity in multiple bus systems can be much reduced by removing connections which are only needed for highly improbable request patterns. With this approach, performance comparable to that of the original multiple bus system could be achieved while significantly reducing memory bus connectivity. The new architecture thus obtained (Probabilistically load reduced connection multiple bus system, or PRMB in short) might …
