Complete-Range Activity-Based Rtl Power Estimation, Nur Kurt-Karsilayan

Dissertations and Theses

In recent years, power consumption has become a major concern in the electronic industry. Power reduction can be accelerated in the design cycle by fast and accurate power estimation tools. Since the units of lower-levels of design abstraction are transistors or gates, power estimation becomes a slow process at these levels. Therefore designers need to have tools for fast and accurate power estimation at the higher levels of design abstraction such as register transfer level (RTL).

A novel RTL power estimation technique called CRAB-RPE will be presented in this thesis. The CRAB power model is built upon four important properties …

Routing, Driven Placement For Atmel 6000 Architecture Fpgas, Songhua Zhang

Dissertations and Theses

Based on the concept of Cell Binary Tree (CBT), a new technique for mapping combination circuits into ATMEL 6000 Architecture FPGAs is presented in this thesis. Cell Binary Tree (CBT) is a net-list representation of combinational circuits. For each node of CBT there is a distinguished variable associated with it, the node itself represents a certain logic function, which is selected according to target FPGA architecture. The proposed CBT placement algorithms preserve local connectivity and allow better mapping into ATMEL FPGA. Experiments reveal that the new mapping technique achieved reduction in a number buses used for routing comparing with previously …

The Juice Is Loose?: A Qualitative Study Of Employees' Perceptions Of Informal And Formal Communication Channels, Warren Jerome Brown

An Ice Shelf Mechanism For Heinrich Layer Production, Christina L. Hulbe

Geology Faculty Publications and Presentations

The effect of an ice shelf in the Labrador Sea on ice-rafted sediment delivery to the glacial North Atlantic is investigated using a finite element numerical model of ice shelf flow. Discharge into the shelf from Hudson Strait creates a thick central core, extending downstream into the shelf, that is flanked by relatively thin ice. Melting at the base of the deep keel would produce cool, fresh water which would rise to refreeze along the keel's flanks. Debris deposited by melting deep central ice could create the Heinrich layers observed in the Labrador Sea while the debris-rich ice protected by …

The Effectiveness Of Planned Transitions Therapy In The Treatment Of Three Children With Developmental Verbal Dyspraxia, Emily M. Campbell

Dissertations and Theses

The intent of this investigation was to note whether use of Planned Transitions Therapy (PTT) would help to improve the intelligibility of 3 children with developmental verbal dyspraxia (DVD). PTT is an approach that emphasizes the sequencing of lingual movements from one place of articulation to the next for the production of speech. Rather than focusing on the production of sounds, exercises with PTT focus on transitions between sounds.

Three male subjects presenting characteristics of DVD received 30-minute treatment sessions with a traditional intervention approach for 6 weeks. Each subject also received periods of intervention with PTT. Subject A received …

The Concept Of Trustworthiness: A Cross-Cultural Comparison Between Japanese And U.S. Business People, Masami Nishishiba

Dissertations and Theses

Since trust has been reported as an important component in both Japanese and U.S. organizations, the indication of lack of trust between Japanese and U.S. employees in Japanese subsidiaries is of great concern to management. If one wants to improve the level of trust between Japanese and U.S. employees, one must explore the reasons why they sometimes do not trust each other. Since there may be cultural differences between the two groups in the concept of trustworthiness, the first step is to examine whether Japanese and U.S. employees share the same notion of what constitutes a trustworthy person. Therefore, the …

The Effect Of Lymph Sac Pressure On Lymph Heart Pressure Development In The Toad Bufo Marinus, Michael Georgitsis

Dissertations and Theses

Lymph hearts play an important role in blood volume regulation in anurans by controlling the movement of fluid from the lymphatic spaces to the vasculature. The anatomical continuity between lymph sacs and lymph hearts predicts a coupling of pressure between the two structures which may represent a physical basis for lymph heart regulation. The precise relationship between lymph heart pressure and lymph heart output was not examined so that conclusions regarding changes in work performed by the hearts as a result of changing lymph sac pressure could not be made. However, increases in lymph sac pressure led to increases in …

A Comparison Of Speech Onset Latencies Between Persons Who Stutter And Persons Who Do Not Stutter Across Varied Phonological Priming Conditions, Brian Joseff Riffel

Dissertations and Theses

A recent theory of stuttering, the "Covert Repair Hypothesis of Disfluencies" (Kolk & Postma, in press; Postma & Kolk, 1992, 1993), accounts for the difference between persons who stutter (PWS) and persons who do not stutter (PWNS) by concluding that PWS are slower than PWNS in their phonological encoding abilities. This belief is supported through experimental studies by Bosshardt (1990) and Postma et al (1990), both of which found PWS to be slower than PWNS in silent reading tasks. In addition, Wijnen and Boers (1994) found that PWS demonstrate longer speech onset latencies than PWNS at baseline, but then approximate …

Effects Of Orofacial Clefts On Early Career Maturity, Jeanniekay Mccall

Dissertations and Theses

The purpose of this study was to investigate career maturity in 14- and 17- year-old male and female adolescents with cleft lip and palate. Career maturity is defined as the repertoire of behaviors pertinent to identifying, choosing, planning, and executing career goals available to a specific individual as compared with those possessed by a peer group. Clefting is a congenital anomaly that occurs in approximately 1 in every 600 newborns and can result in facial scarring and speech deviations that may last throughout life, and may result in complications such as withdrawal, inhibition, lower self-esteem, and increasing self-doubt regarding interpersonal …

The Role Of The Hepatic Vagus In The Pathogenesis Of Fever, Christopher Todd Simons

Dissertations and Theses

Recent evidence has suggested a role of vagal afferents in the pathogenesis of fever. Although bilateral truncal subdiaphragmatic vagotomy has been shown to attenuate the febrile response to lipopolysaccharide (LPS) and interleukin-1, no study has yet been able to verify which of the five subdiaphragmatic vagal branches (viz., the anterior and posterior celiac branches, the anterior and posterior gastric branches, and the hepatic branch) is responsible for communicating this signal. The present study tested the hypothesis that the hepatic vagal branch mediates pyrogenic signals from the periphery to the brain. Male Wistar rats underwent one of four selective …

Seaman's Valley And Maroon Material Culture In Jamaica, E. Kofi Agorsah

Black Studies Faculty Publications and Presentations

Seaman's Valley site was one of the few known places in Jamaica where the Maroons came into face to face combat with the colonial military in a battle that featured the largest force ever sent against the Maroons. In that encounter the colonial forces were routed in a total defeat resulting in the abandonment of arms and ammunition and personnel. This paper compares the material culture from the Seaman's Valley site and Nanny Town. This paper will then show the significance of the longstanding strategic relationship between the two locations during the Maroon struggle for freedom and even after peace …

Real Ear To Coupler Differences In Children And The Effects Of Hearing And Microphone Location, Cindy Richardson

Dissertations and Theses

The early identification of hearing loss and selection of appropriate amplification are the most important goals for children with hearing impairment. Selection of appropriate amplification for a pediatric population involves maximizing the hearing impaired child's residual hearing, for development of speech and language. In addition, it is important to consider the acoustic differences between the 2 cc coupler versus the real ear.

During the hearing aid selection process, it is customary to predict how a hearing aid will respond in the real ear, based upon a given 2 cc coupler response. Killion and Monser (1980) developed a formula for converting …

Grandmothers Laughing: Intergenerational Transmission Of Cultural Beliefs About Pregnancy And Childbirth Among Native American Women, Claudia Robin Long

Dissertations and Theses

This dissertation reports findings from a qualitative study of intergenerational transmission of pregnancy and childbirth information among Native American women. Proposed is a theory of intergenerational transmission that explains four pathways used by Indian women to gain information about pregnancy and childbirth. Antecedent, consequent, and core elements are associated with the transmission process.

Discriminant sampling was used to identify the middle generation of Indian mothers and grandmothers, between 36 and 65 years of age, residing on or near the reservation, with experience of assimilation policies that had moved off-reservation temporarily. The researcher used the grounded theory method to analyze responses …

High-Performance Input/Output Circuit For Cmos Integrated Circuit Interface, Chee How Lim

Dissertations and Theses

In recent years, strong demand for high-performance electronic products has fueled the need for high-speed and high-integration VLSI circuits. This demand is expected to continue growing in the future, which will lead to development of IC's that are much more compact and operate at higher frequencies. As a result, preserving signal integrity for proper IC communications becomes an increasingly difficult challenge.

In this thesis, an understanding of IC noise in relation to IC packaging is sought. An IC package is modeled with sophisticated 3-D simulators to extract its corresponding parasitics. These parasitics, expressed in terms of resistance, inductance, and capacitance …

Dynamic Load Distribution In Mist, K. Al-Saqabi, R. M. Prouty, Dylan Mcnamee, Steve Otto, Jonathan Walpole

Computer Science Faculty Publications and Presentations

This paper presents an algorithm for scheduling parallel applications in large-scale, multiuser, heterogeneous distributed systems. The approach is primarily targeted at systems that harvest idle cycles in general-purpose workstation networks, but is also applicable to clustered computer systems and massively parallel processors. The algorithm handles unequal processor capacities, multiple architecture types and dynamic variations in the number of processes and available processors. Scheduling decisions are driven by the desire to minimize turnaround time while maintaining fairness among competing applications. For efficiency, the virtual processors (VPs) of each application are gang scheduled on some subset of the available physical processors.

The Language Of Transformation In A "Conversation For Possibility": A Metaphor Analysis, Deborah Jean Gabbert

Dissertations and Theses

Metaphor allows us to understand and experience "relatively abstract or unstructured subject matter in terms of more concrete, or at least more highly structured subject matter". Lakoff and Johnson's (1980) and Lakoff's (1993) contemporary theory of metaphor contends that: metaphor is fundamentally conceptual; metaphoric structuring is the basis for the organization and functioning of much of the ordinary human conceptual system; and metaphorical language found in everyday speech is a surface manifestation of underlying conceptual metaphors. The metaphors most salient in a culture's discourse will reveal something about what is thinkable, knowable, and doable in that culture. Metaphors have the …
