An Algorithm for the PLA Equivalence Problem

An Algorithm for the PLA Equivalence Problem

Date: December 1995
Creator: Moon, Gyo Sik
Description: The Programmable Logic Array (PLA) has been widely used in the design of VLSI circuits and systems because of its regularity, flexibility, and simplicity. The equivalence problem is typically to verify that the final description of a circuit is functionally equivalent to its initial description. Verifying the functional equivalence of two descriptions is equivalent to proving their logical equivalence. This problem of pure logic is essential to circuit design. The most widely used technique to solve the problem is based on Binary Decision Diagram or BDD, proposed by Bryant in 1986. Unfortunately, BDD requires too much time and space to represent moderately large circuits for equivalence testing. We design and implement a new algorithm called the Cover-Merge Algorithm for the equivalence problem based on a divide-and-conquer strategy using the concept of cover and a derivational method. We prove that the algorithm is sound and complete. Because of the NP-completeness of the problem, we emphasize simplifications to reduce the search space or to avoid redundant computations. Simplification techniques are incorporated into the algorithm as an essential part to speed up the the derivation process. Two different sets of heuristics are developed for two opposite goals: one for the proof of equivalence ...

Alterations in Human Baroreceptor Reflex Regulation of Blood Pressure Following 15 Days of Simulated Microgravity Exposure

Alterations in Human Baroreceptor Reflex Regulation of Blood Pressure Following 15 Days of Simulated Microgravity Exposure

Date: August 1993
Creator: Crandall, Craig G. (Craig Gerald)
Description: Prolonged exposure to microgravity is known to invoke physiological changes which predispose individuals to orthostatic intolerance upon readaptation to the earth's gravitational field. Attenuated baroreflex responsiveness has been implicated in contributing to this inability to withstand orthostatic stress. To test this hypothesis, eight individuals were exposed to 15 days of simulated microgravity exposure using the 6° head-down bed rest model. Prior to, and after the simulated microgravity exposure, the following were assessed: a) aortic baroreflex function; b) carotid baroreflex function; c) cardiopulmonary baroreflex function; and d) the degree of interaction between the cardiopulmonary and carotid baroreflexes.

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing

Date: August 1990
Creator: Houtz, Andrew W. (Andrew William)
Description: This study explores the possibility that attentional deficits are an early clinical symptom of Alzheimer's disease. The three goals are to demonstrate that individuals with Alzheimer's disease are impaired on tasks of attentional processing, to compare the sensitivity of currently used measures of attention to attentional dysfunction, and to compare the behavioral response styles (errors of commission) of Alzheimer's disease subjects and non-impaired subjects. The subjects were 22 males and 46 females with a mean age of 70.76 years. Thirty-six had the presumptive diagnosis of Alzheimer's disease; 18 were identified as mildly impaired and 18 as moderately impaired on the Cognitive Capacity Screening Examination. The remaining 32 subjects comprised the non-impaired control group. Five measures of attention were administered to all participants: the Digit Span Subtest of the WAIS-R, the Seashore Rhythm Test of the Halstead-Reitan Neuropsychological Battery, the Vigilance and Distractibility tasks of the Gordon Diagnostic System, and the Concentration/Interference task. The results show a significant difference in attentional processing between normal (non-impaired) subjects and subjects diagnosed with Alzheimer's disease. All measures of attention used in this study, except the Concentration/Interference task, differentiated normal subjects from moderately impaired Alzheimer's disease subjects. The Digit Span Subtest and the Seashore Rhythm ...

Ambiguity of Loss, Anticipatory Grief, and Boundary Ambiguity in Caregiver Spouses and Parents

Ambiguity of Loss, Anticipatory Grief, and Boundary Ambiguity in Caregiver Spouses and Parents

Date: August 1993
Creator: Rider, Jan, K. (Jan Kathleen)
Description: The purpose of the present cross-sectional study was to examine the effects of ambiguity of loss and type of caregiver-to-patient relationship on anticipatory grief, negative physical and psychological outcomes associated with grief, and boundary ambiguity in family caregivers of chronically ill patients. Questionnaires were completed by 23 parents of ill children and 30 spouses of ill mates. Using an original and a revised concept for level of ambiguity, partial support was found for the prediction that parents and spouses in high ambiguity of loss circumstances would report more anticipatory grief than those in low ambiguity ones. Contrary to prediction, a slight but nonsignificant trend occurred for parents and spouses in low ambiguity situations to report more negative physical and psychological effects associated with grief as well. Level of ambiguity was not found to impact boundary ambiguity as had been hypothesized. Spouses reported more boundary ambiguity than parents, regardless of level of ambiguity of the loss. Contrary to prediction that parents would report less anticipatory grief and more negative physical and psychological outcomes than spouses, generally, no significant differences were found between the two groups. However, using the original concept of ambiguity, parents did tend to recall more past grief than ...

The American Eve: Gender, Tragedy, and the American Dream

The American Eve: Gender, Tragedy, and the American Dream

Date: May 1993
Creator: Long, Kim Martin
Description: America has adopted as its own the Eden myth, which has provided the mythology of the American dream. This New Garden of America, consequently, has been a masculine garden because of its dependence on the myth of the Fall. Implied in the American dream is the idea of a garden without Eve, or at least without Eve's sin, traditionally associated with sexuality. Our canonical literature has reflected these attitudes of devaluing feminine power or making it a negative force: The Scarlet Letter, Moby-Dick, Adventures of Huckleberry Finn, The Great Gatsby, and The Sound and the Fury. To recreate the Garden myth, Americans have had to reimagine Eve as the idealized virgin, earth mother and life-giver, or as Adam's loyal helpmeet, the silent figurehead. But Eve resists her new roles: Hester Prynne embellishes her scarlet letter and does not leave Boston; the feminine forces in Moby-Dick defeat the monomaniacal masculinity of Ahab; Miss Watson, the Widow Douglas, and Aunt Sally's threat of civilization chase Huck off to the territory despite the beckoning of the feminine river; Daisy retreats unscathed into her "white palace" after Gatsby's death; and Caddy tours Europe on the arm of a Nazi officer long after Quentin's suicide, ...

American Grotesque from Nineteenth Century to Modernism: the Latter's Acceptance of the Exceptional

American Grotesque from Nineteenth Century to Modernism: the Latter's Acceptance of the Exceptional

Date: August 1994
Creator: Kisawadkorn, Kriengsak
Description: This dissertation explores a history of the grotesque and its meaning in art and literature along with those of its related term, the arabesque, since their co-existence, specifically in literature, is later treated by a well-known nineteenth-century American writer in Tales of the Grotesque and Arabesque- Theories or views of the grotesque (used in literature), both in Europe and America, belong to twelve theorists of different eras, ranging from the sixteenth century to the present period, especially Modernism (approximately from 1910 to 1945)--Rabelais, Hegel, Scott, Wright, Hugo, Symonds, Ruskin, Santayana, Kayser, Bakhtin, (William Van) O'Connor, and Spiegel. My study examines the grotesque in American literature, as treated by both nineteenth-century writers--Irving, Poe, Hawthorne, and, significantly, by modernist writers--Anderson, West, and Steinbeck in Northern (or non-Southern) literature; Faulkner, McCullers, and (Flannery) O'Connor in Southern literature. I survey several novels and short stories of these American writers for their grotesqueries in characterization and episodes. The grotesque, as treated by these earlier American writers is often despised, feared, or mistrusted by other characters, but is the opposite in modernist fiction.

Analyses of Particulate Contaminants in Semiconductor Processing Fluids

Analyses of Particulate Contaminants in Semiconductor Processing Fluids

Date: August 1998
Creator: Xu, Daxue
Description: Particle contamination control is a critical issue for the semiconductor industry. In the near future, this industry will be concerned with the chemical identities of contaminant particles as small as 0.01 pm in size. Therefore, analytical techniques with both high chemical sensitivity and spatial resolution are required. Transmission electron microscopy (TEM) provides excellent spatial resolution and yields structural and compositional information. It is rarely used, however, due to the difficulty of sample preparation. The goals of this research are to promote the use of TEM as an ultrafine particle analysis tool by developing new sample preparation methods, and to exploit the new TEM techniques for analysis of particles in semiconductor processing fluids. A TEM methodology for the analysis of particulate contaminants in fluids with an elemental detectability limit as low as 0.1 part per trillion (ppt), and a particle concentration detectability limit as low as 1 particle/ml for particles greater than 0.2 pm was developed and successfully applied to the analysis of particles in HF, H202, de-ionized (DI) water, and on the surface of an electronic device. HF samples from three manufacturers were examined. For HF (B), the maximum particle concentration was 8.3 x 103 particles/ml. Both a viscous material ...

Analysis of a Human Transfer RNA Gene Cluster and Characterization of the Transcription Unit and Two Processed Pseudogenes of Chimpanzee Triosephosphate Isomerase

Date: August 1990
Creator: Craig, Leonard C. (Leonard Callaway)
Description: An 18.5-kb human DNA segment was selected from a human XCharon-4A library by hybridization to mammalian valine tRNAiAc and found to encompass a cluster of three tRNA genes. Two valine tRNA genes with anticodons of AAC and CAC, encoding the major and minor cytoplasmic valine tRNA isoacceptors, respectively, and a lysine tRNAcuu gene were identified by Southern blot hybridization and DNA sequence analysis of a 7.1-kb region of the human DNA insert. At least nine Alu family members were found interspersed throughout the human DNA fragment. The tRNA genes are accurately transcribed by RNA polymerase III in a HeLa cell extract, since the RNase Ti fingerprints of the mature-sized tRNA transcription products are consistent with the DNA sequences of the structural genes. Three members of the chimpanzee triosephosphate isomerase (TPI) gene family, the functional transcription unit and two processed pseudogenes, were characterized by genomic blotting and DNA sequence analysis. The bona fide TPI gene spans 3.5 kb with seven exons and six introns, and is the first complete hominoid TPI gene sequenced. The gene exhibits a very high identity with the human and rhesus TPI genes. In particular, the polypeptides of 248 amino acids encoded by the chimpanzee and human ...

An Analysis of a Major State and a Small Local Newspaper Reporting on Public Education in the Years 1988 and 1993

Date: May 1996
Creator: Gindt, Gerard J. (Gerard Joseph)
Description: This study was conducted to analyze the differences in the news coverage of public education by a state and local newspaper, to ascertain if trends exist in the coverage of topics, and if the coverage is negative, positive, or neutral. All issues of The Dallas Morning News and The Piano Star Courier from the years 1988 and 1993 were evaluated. All articles about public education (with the exception of athletics, obituaries, and advertisements) were evaluated using a content analysis form. The content analysis form provided information for classifying all articles. Information was tallied for the number of articles and column inches by newspaper and category. Findings indicated a number of differences between the two newspapers in 1988 and 1993. The Dallas Morning News increased the number of articles and column inches of space it committed to the coverage of public education from 1988 to 1993. During the same period The Piano Star Courier reduced both the number of articles and column inches of space which it used for the topic of education. The Piano Star Courier began publishing editions on only five of the seven days per week in February, 1993. The Dallas Morning News reduced its local coverage and ...

An Analysis of Corporate Accounting and Reporting Practices in Bahrain

An Analysis of Corporate Accounting and Reporting Practices in Bahrain

Date: December 1993
Creator: Abdul-Rahim, Hassan M.
Description: The primary objective of this dissertation is to determine the factors that have shaped the corporate financial reporting practices in Bahrain. Prior researchers have offered two explanations, environmental factors and cultural importation, for the emergence of financial reporting practices in developing countries. The environmental explanation suggests that a nation's financial reporting practices will be shaped by its socioeconomic structure. The cultural importation explanation states that the desire for international legitimacy creates incentives for developing nation to adopt Western financial reporting practices. Bahrain provided an excellent environment in which to examine the two explanations since its public and closed corporations have similar economic characteristics. Only public corporations are legally required to publish financial reports. I posited that public corporations would try to gain legitimacy for their published reports by adopting Western standards, while closed corporations would not have a similar incentive. I used an interpretive framework to analyze the Bahrain socioeconomic environment and to examine the general financial reporting practices of Bahraini corporations. I found that closed corporations provided data responsive to the Bahraini environment. Public corporations, however, adopted International Accounting Standards. My analysis supported prior researchers7 findings that colonialism, the need for international legitimacy, and international audit firms were important ...

An Analysis of Factors Associated with Voluntary Disclosure of Management's Responsibilities for Internal Control

An Analysis of Factors Associated with Voluntary Disclosure of Management's Responsibilities for Internal Control

Date: August 1992
Creator: Tanner, Margaret Morgan
Description: The purpose of this study was to identify company characteristics associated with the presence of disclosures regarding internal control in the annual report. Gibbins, Richardson and Waterhouse [1990] have developed a framework from which to examine financial disclosure,. These authors define two dimensions of a company's disclosure position; opportunism and ritualism. I examined the association between variables representing the dimensions identified by these authors and a company's decision regarding disclosure of a management report on internal control. I compared specific characteristics of companies disclosing this information to those of companies not disclosing. The dependent variable represented the presence or absence of disclosure. I used logit analysis to test the significance of the chosen characteristics relative to the decision to include or exclude a management report on internal control in the annual report. My results were consistent with the existence of ritualism with respect to this issue. Reporting on internal controls was associated with membership in the Financial Executives Institute, auditor choice, certain industry designations and prior inclusion of such a report. FEI membership was closely related to initial reporting decisions as well'. I found evidence of opportunism as well. The likelihood of reporting on internal controls was related to company ...
