Multifractal Analysis Of Memory Usage Patterns, Jonathan Browning Crowell Dec 2001

Multifractal Analysis Of Memory Usage Patterns, Jonathan Browning Crowell

Graduate Theses, Dissertations, and Problem Reports (ETD)

The discovery of fractal phenomenon in computer-related areas such as network traffic flow leads to the hypothesis that many computer resources display fractal characteristics. The goal of this study is to apply fractal analysis to computer memory usage patterns. We devise methods for calculating the Holder exponent of a time series and calculating the fractal dimension of a plot of a time series. These methods are then applied to memory-related data collected from a Unix server. We find that our methods for calculating the Holder exponent of a time series yield results that are independently confirmed through calculation of the …

Cmos Fingerprint Sensor Electrostatic Modeling, Praveen Kumar Soora May 2001

Cmos Fingerprint Sensor Electrostatic Modeling, Praveen Kumar Soora

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of Biometrics in personal identification is an important emerging technology in modern electronic society. Fingerprints are one of the most popular biometric technologies, currently used in majority of biometric applications. In recent years, solid-state capacitive fingerprint sensors which image fingerprints using Silicon CMOS Technology are gaining much acceptance in the market. This research work is carried out to quantify and explore approaches for achieving improved sensitivity of the capacitive imaging process through reduction of parasitic capacitances and sensor cell scaling for future generation devices. Evaluation of sensor cell and array geometries was completed using a commercial 2-D electrostatic …

The Effect Of Role, Age, Gender, And Years Of Experience Upon The Perceived Importance Of Clinical Teacher Behavior Categories In Athletic Training Education., Christine A. Lauber Jan 2001

The Effect Of Role, Age, Gender, And Years Of Experience Upon The Perceived Importance Of Clinical Teacher Behavior Categories In Athletic Training Education., Christine A. Lauber

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study investigated the effect of athletic training education program role (program director or clinical instructor), age, gender, and years of experience upon the perceived importance of instructional, interpersonal, evaluative, professional, and personal categories of clinical teacher behaviors and characteristics. The population of the study consisted of Commission on Accreditation of Allied Health Education Programs (CAAHEP) accredited entry-level undergraduate athletic training education programs. All CAAHEP accredited entry-level undergraduate athletic training education programs were surveyed. Respondents to the survey were program directors and full-time on campus clinical instructors serving in these programs. The Clinical Instructor Behavior Instrument, developed by the researcher, …

The Effects Of Smoking On Blood Cells, And The Association Between Smoking And Nutrient Intake Among Pregnant Women Residing In Northern West Virginia., Rebecca King Jan 2000

The Effects Of Smoking On Blood Cells, And The Association Between Smoking And Nutrient Intake Among Pregnant Women Residing In Northern West Virginia., Rebecca King

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cigarette smoking is a risk factor in respiratory disease, cancer and cardiovascular diseases and other health problems. The purpose of the study was to determine the effects of smoking on white blood cells and to assess the relation between smoking, red blood cells, nutrient intake, and newborn weight among pregnant WIC participants residing in Northern West Virginia. The study consisted of 110 pregnant women. Data for this study were obtained by in-person interviews at the clinical site or at the participants' home. The findings of the study indicated that the smokers, white blood cells and lymphocytes were positively associated with …

Use Of Wavelet-Packet Transforms To Develop An Engineering Model For Multifractal Characterization Of Mutation Dynamics In Pathological And Nonpathological Gene Sequences, David Lee Walker May 1999

Use Of Wavelet-Packet Transforms To Develop An Engineering Model For Multifractal Characterization Of Mutation Dynamics In Pathological And Nonpathological Gene Sequences, David Lee Walker

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study uses dynamical analysis to examine in a quantitative fashion the information coding mechanism in DNA sequences. This exceeds the simple dichotomy of either modeling the mechanism by comparing DNA sequence walks as Fractal Brownian Motion (fbm) processes. The 2-D mappings of the DNA sequences for this research are from Iterated Function System (IFS) (Also known as the "Chaos Game Representation" (CGR)) mappings of the DNA sequences. This technique converts a 1-D sequence into a 2-D representation that preserves subsequence structure and provides a visual representation. The second step of this analysis involves the application of Wavelet Packet Transforms, …

Improvement Of Instruction In Special Education: An Ethnographic Look., Wanda Lee Letendre Jan 1999

Improvement Of Instruction In Special Education: An Ethnographic Look., Wanda Lee Letendre

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was to understand how a special education supervisor, four beginning special education teachers and their building principal experienced improvement of instruction. The study was conducted in four special education classrooms in a county with a school-aged population of approximately 14,000 students. The county was located in a rural, upper Southern state. Data were collected primarily from January through June of 1997. Using qualitative methodology, data were collected by use of participant observation, interviews, and analysis of documents pertinent to improvement of instruction. Field notes, transcripts, and pertinent information from documents were entered into Ethnograph software …

Visual And Iconographic Design Principles: Implications For Computer-Assisted Instruction., Lindia Lee Gordon Jan 1996

Visual And Iconographic Design Principles: Implications For Computer-Assisted Instruction., Lindia Lee Gordon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was to provide educators and developers of computer-assisted instruction with a validated, concise list of visual and iconographic design principles that should be considered when designing graphical icons to stimulate learning as a part of the user interface of their courseware packages in order to create more effective learning. A panel of 12 experts in a modified Delphi study identified and validated visual and iconographic design principles necessary in the development of icons for CAI. As a result of this study, 37 visual and iconographic design principles were identified and validated. The final conclusions of …

Effects Of Task And Environment-Related Variables On Individuals' Lifting Capabilities While Wearing Protective Clothing., Mohamed Zaki Ramadan Jan 1988

Effects Of Task And Environment-Related Variables On Individuals' Lifting Capabilities While Wearing Protective Clothing., Mohamed Zaki Ramadan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study was conducted to evaluate the lifting capabilities of individuals while wearing protective clothing in a hot environment and to investigate the behavior of the physiological stresses induced by the lifting process associated with those variables. In order to achieve the objectives of this research, two separate studies were conducted. The first part was an acclimatization and training program followed by a psychophysical experiment. Five male subjects, 28 to 31 years of age, participated in this study. They were heat acclimatized and trained for ten days prior to participation in the main experiment. The independent variables studied in the …

Acclimatization Of Older Men To Work In Heat., Edward Payson Daugherty Jan 1987

Acclimatization Of Older Men To Work In Heat., Edward Payson Daugherty

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is a paucity of evidence to support the hypothesis that there is no significant difference (NSD) between the rate of acclimatization gain and loss of young and old men as they work in a hot environment. Ten young men (Group 1 (x age 24.8 years)) and 5 older men (Group 2 (x age 64.4 years)) volunteered to complete a 39 day exercise regimen in an environmental chamber. Days 1-4 were the Baseline Phase (BL) (68-72 F{dollar}\\sp\\circ{dollar} dry bulb (DB), relative humidity (RH) 40%). Days 5-18 were the Acclimatization Phase (AC) (DB = 100 F{dollar}\\sp\\circ{dollar}, RH = 40%). Days 19-39 …
