Max Operation In Statistical Static Timing Analysis On The Non-Gaussian Variation Sources For Vlsi Circuits, Abu M. Baker
Max Operation In Statistical Static Timing Analysis On The Non-Gaussian Variation Sources For Vlsi Circuits, Abu M. Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
As CMOS technology continues to scale down, process variation introduces significant uncertainty in power and performance to VLSI circuits and significantly affects their reliability. If this uncertainty is not properly handled, it may become the bottleneck of CMOS technology improvement. As a result, deterministic analysis is no longer conservative and may result in either overestimation or underestimation of the circuit delay. As we know that Static-Timing Analysis (STA) is a deterministic way of computing the delay imposed by the circuits design and layout. It is based on a predetermined set of possible events of process variations, also called corners of …
Object Detection Using Contrast Enhancement And Dynamic Noise Reduction, Justin Lee Baker
Object Detection Using Contrast Enhancement And Dynamic Noise Reduction, Justin Lee Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
Edge detection is one of the most important steps a computer must perform to gain understanding of an object in a digital image either from disk or from video feed. Edge detection allows for the computer to describe the shape of the objects in an image and create a pixel boundary defining what is considered part of an object, and what is not. Cannys edge detection algorithm is one of the most robust and accurate of these edge detection algorithms. However, as with many algorithms in image processing, there are many cases where the algorithm does not perform as well …

Developing Ethical Competence: The Perspective Of Nurse Educators From Pre-Licensure Baccalaureate Nursing Programs Accredited By The Commission On Collegiate Nursing Education, Jennifer Lee Bartlett
UNLV Theses, Dissertations, Professional Papers, and Capstones
Nurses face ethically-charged situations every day, yet ethics education is not universally integrated into pre-licensure baccalaureate nursing programs. Like other forms of competence, ethical competence requires development. Nurse educators are poised to impact on the competence of their students, both defining the ethics content and designing students' exposure. The purpose of this study is to describe the concept of ethical competence from the perspective of baccalaureate nursing faculty and describe current methods of integration and evaluation of ethics education in pre-licensure baccalaureate nursing programs. This research will be conducted using a sequential (quantitative-qualitative) mixed method approach. The first phase of …

Temperature Trends And Urban Heat Island Intensity Mapping Of The Las Vegas Valley, Adam Leland Black
UNLV Theses, Dissertations, Professional Papers, and Capstones
Modified urban climate regions that are warmer than rural areas at night are referred to as Urban Heat Islands or UHI. Islands of warmer air over a city can be 12 degrees Celsius greater than the surrounding cooler air. The exponential growth in Las Vegas for the last two decades provides an opportunity to detect gradual temperature changes influenced by an increasing presence of urban materials. This thesis compares ground based thermometric observations and satellite based remote sensing temperature observations to identify temperature trends and UHI areas caused by urban development.
Analysis of temperature trends between 2000 and 2010 at …
Actresses Redefining Theater And Femininity In Eighteenth-Century France, Rebecca Anne Bolen
Actresses Redefining Theater And Femininity In Eighteenth-Century France, Rebecca Anne Bolen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Published in 1798 and 1800, the memoires of Hypolite Clairon and Marie-Françoise Marchand Dumesnil relate the experiences and values of individuals who lived through massive social and cultural, and eventually political, changes. How and when these two women felt the need to adhere to society's standards in comparison to those instances when they were confident enough to assert themselves illuminates the ways in which developing a public persona could open up a space for women to stretch the boundaries of feminine self-fashioning. This space was not unlimited and may have depended on actresses making concessions to societal expectations. It was …

The Lived Experiences Of Acute-Care Bedside Registered Nurses Caring For Patients And Their Families With Limited English Proficiency, Jami-Sue Coleman
UNLV Theses, Dissertations, Professional Papers, and Capstones
Approximately 8.6% of the total U.S. population is considered limited English proficient (LEP), a term that has been used by official US federal policy and will be used throughout this study. In a landmark report, the Institute of Medicine found that minorities received lower-quality health care than Caucasians even when insurance status, income, and other factors were equivalent. These differences were tied to issues such as bias, stereotypes and communication barriers between patients and their caregivers. In the hospital setting, registered nurses provide the most direct contact with patients and their families. Effective communication between patients and health care professionals …

Investigating Potential Factors That Influence Recruitment For Parenting Skills Classes, Rachel Elizabeth Davis
UNLV Theses, Dissertations, Professional Papers, and Capstones
Juvenile delinquency and child maltreatment are prevalent in the U.S., particularly among ethnic minority children. Although parent skills training is effective in preventing these problems, recruitment and retention rates of parents from ethnic, racial, and socioeconomic minority groups are less than satisfactory. In a qualitative study of 13 high-risk African American mothers, Davis (2009) investigated the deterrents to recruitment and participation for parent skills training programs. The resulting theory, the Mothers Shouldn't Need Help Script, explicates the relationship between the beliefs reported by these mothers and participation in parenting skills classes. To build on these findings, the overarching purpose of …

Computer-Based Stereoscopic Parts Recognition For Robotic Applications, Ahmad A. Fayed
Computer-Based Stereoscopic Parts Recognition For Robotic Applications, Ahmad A. Fayed
UNLV Theses, Dissertations, Professional Papers, and Capstones
Most of robotic handling and assembly operations are based on sensors such as range and touch sensors. In certain circumstances, such as in the presence of ionizing radiation where most customary sensors will degrade over time due to radiation exposure, these sensors won't function properly. Utilizing two or more cameras (stereo vision) located outside the target zone and analyzing their images to identify location and dimensions of parts within the robot workspace is an alternative for using sensors. Object Recognition is affected by the light condition which oftentimes causes the gray-scale or red, green, and blue values to have a …

Design And Fabrication Of An Infrared Optical Pyrometer Asic As A Diagnostic For Shock Physics Experiments, Jared Gordon
UNLV Theses, Dissertations, Professional Papers, and Capstones
Optical pyrometry is the sensing of thermal radiation emitted from an object using a photoconductive device to convert photons into electrons, and is an important diagnostic tool in shock physics experiments. Data obtained from an optical pyrometer can be used to generate a blackbody curve of the material prior to and after being shocked by a high speed projectile. The sensing element consists of an InGaAs photodiode array, biasing circuitry, and multiple transimpedance amplifiers to boost the weak photocurrent from the noisy dark current into a signal that can eventually be digitized. Once the circuit elements have been defined, more …
Managerial Behavioral Complexity And The Collegiate Registrar, Katherine Jeanette Humphreys
Managerial Behavioral Complexity And The Collegiate Registrar, Katherine Jeanette Humphreys
UNLV Theses, Dissertations, Professional Papers, and Capstones
Colleges often put an emphasis on the student experience and the student as a "customer" that should be courted, tracked, and understood. Yet, there are few academic studies that address the administrative roles that oversee the offices with direct student contact. All colleges have a registrar's office, or an office responsible for much of the institution's infrastructure from enrollment to graduation. Gunn & Backes (1992) point out, "In a climate where schools are competing for the best students, something as simple as making the registration system run smoothly and efficiently for the student can have major impacts, providing services that …

What Works In Suicide Bereavement: What Helps And What Hurts?, Quintin Hunt
UNLV Theses, Dissertations, Professional Papers, and Capstones
Suicide is one of the most painful grief experiences that any family may experience. The suicide bereavement literature, though small, is replete with research that shows family and systemic impacts of suicide. The literature also includes constant calls for family- and systemic-based intervention as every part of society is impacted. Research in the field of marriage and family therapy, however, has ignored suicide and suicide bereavement almost entirely. The purpose of this qualitative study is to develop a more thorough understand of the grief that survivors of suicide experience and to systemically understand what helps and hurts the grieving process. …

Nonlinear Adaptive Diffusion Models For Image Denoising, Ajay Kumar Mandava
UNLV Theses, Dissertations, Professional Papers, and Capstones
Most of digital image applications demand on high image quality. Unfortunately, images often are degraded by noise during the formation, transmission, and recording processes. Hence, image denoising is an essential processing step preceding visual and automated analyses. Image denoising methods can reduce image contrast, create block or ring artifacts in the process of denoising. In this dissertation, we develop high performance non-linear diffusion based image denoising methods, capable to preserve edges and maintain high visual quality. This is attained by different approaches: First, a nonlinear diffusion is presented with robust M-estimators as diffusivity functions. Secondly, the knowledge of textons derived …
