Benchmarking Permutation Flow Shop Problem: Adaptive And Enumerative Approaches Implementations Via Novel Threading Techniques, Hari Prasad Sapkota

UNLV Theses, Dissertations, Professional Papers, and Capstones

A large number of real-world planning problems are combinatorial optimization problems which are easy to state and have a finite but usually very large number of feasible solutions. The minimum spanning tree problem and the shortest path problem are some which are solvable through polynomial algorithms. Even though there are other problems such as crew scheduling, vehicle routing, production planning, and hotel room operations which have no properties such as to solve the problem with polynomial algorithms. All these problems are NP-hard. The permutation flow shop problem is also NP-hard problem and they require high computation. These problems are solvable …

A Group Development Program Based On Transformational Leadership To Improve Team Performance, Anne-Marie Schenk

UNLV Theses, Dissertations, Professional Papers, and Capstones

As reimbursement models move from volume-based to value-based, organizations increasingly depend on meeting patient outcome goals in order to achieve their budgetary targets. Leadership teams are a vital part of healthcare organizations and their performance is crucial to the overall organization’s performance. The organization of interest saw a group of strong individual leaders struggle with outcome production due, in part, to overall team dysfunction. To address this need, this DNP project is a group development program, based on the concepts of transformational leadership. As functional groups and transformational leaders are known to drive outcomes, when implemented, this program’s goal is …

Prevalence And Use Of High-Fidelity Simulation In Family Nurse Practitioner Programs, Christina Rosa Pendrak Pepin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Family nurse practitioner (FNP) programs represent almost 60% of all accredited primary-care NP programs in the U.S. in 2015. Increased enrollments and creation of new NP programs has led to a shortage of appropriate clinical sites and the increased competition for quality clinical sites. FNP programs have turned towards utilizing innovative ways to address this shortage including the use of high-fidelity simulation. However, a lack of literature supports substituting traditional clinical hours with high-fidelity simulation. Only 45 articles were found over a 35-year period describing the use of high-fidelity simulation in an FNP program and of those published since 2014, …

Estimation Of Stage-Area-Storage Relationships In Reservoirs And Stage-Discharge Relationships In Rivers Using Remotely Sensed Data, Sailuj Shakya

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis estimates the relationships between the water surface levels and quantities of water in reservoirs and rivers using remotely sensed data without any field measurements. However, the accuracies of the estimates were validated using the field measurements from ground stations. The relationships between the water surface levels and quantities are fundamental for monitoring water quantities for the operation of hydraulic structures, as well as analyzing variability and changes in hydrology. Accessibility and transparency are big issues in establishing a monitoring system that can provide field validation of efforts to model global climate systems. Remote sensing has a capability of …

Elucidating The Lasting Influence Of Early Pubertal Timing On Disordered Eating Symptoms, Megan Marie Shope

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Extant data indicate that girls who mature earlier than their peers are at increased risk for disordered eating symptoms. Nonetheless, whether early pubertal timing exerts differential effects across key disordered eating symptoms (e.g., body weight/shape concerns vs. binge eating) and whether pubertal timing effects are present after the completion of puberty (i.e., in adulthood) remains relatively unclear. Additionally, leading theories posit that pubertal increases in adiposity and psychosocial factors (e.g., perceived pressures for thinness) likely underlie the predictive effects of earlier maturation on disordered eating risk, yet few studies have empirically tested this possibility. The current study aimed to …

Cesium Platinum Iodide Perovskite Synthesis, Development And Application In Photovoltaic Devices, Dakota Schwartz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Third generation photovoltaics, including perovskites, are essential to improving solar technology for widespread future use. Perovskite solar cells have surpassed 23.7% power conversion efficiency, comparable to traditional silicon photovoltaic panels. However, these perovskites are fabricated using lead-based compounds, posing toxicity issues. Furthermore, existing perovskites have limited thermal and moisture stability in ambient environments. In order to address toxicity and stability concerns, as well as to maximize photon absorption in solar cells through bandgap optimization, this effort focuses on the development of novel leadfree perovskite materials. A cesium platinum iodide composition is selected as a model system due to the theoretical …

Multi-Resolution Spatio-Temporal Change Analyses Of Hydro-Climatological Variables In Association With Large-Scale Oceanic-Atmospheric Climate Signals, Kazi Ali Tamaddun

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary objective of the work presented in this dissertation was to evaluate the change patterns, i.e., a gradual change known as the trend, and an abrupt change known as the shift, of multiple hydro-climatological variables, namely, streamflow, snow water equivalent (SWE), temperature, precipitation, and potential evapotranspiration (PET), in association with the large-scale oceanic-atmospheric climate signals. Moreover, both observed datasets and modeled simulations were used to evaluate such change patterns to assess the efficacy of the modeled datasets in emulating the observed trends and shifts under the influence of uncertainties and inconsistencies. A secondary objective of this study was to …

Assessing Simulated Transmissivity In Numerical Flow Models Of Complex Hydrogeology, Afan Tarar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accurately extracting a meaningful transmissivity, a target value within one order of magnitude of field estimates, in numerical models poses a significant challenge when modeling complex groundwater systems. Aquifer transmissivity is directly proportional to the aquifer thickness and the estimated aquifer hydraulic conductivity. In complex geologic conditions (especially in fractured systems) with multiple heterogeneous and anisotropic hydrogeologic units, transmissivity can vary over several orders of magnitude.

To extract a meaningful value of transmissivity from a numerical model, a simple five-layer MODFLOW model was constructed. Each layer in the model was assigned a fixed hydraulic conductivity and thickness. The model simulates …

Optimizing Cycle Exercise Performance During Normobaric Hypoxia Exposure, Cierra Brittany Ugale

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: The purpose of the present study was to examine whether implementing factors of OPTIMAL Theory: Enhanced Expectancies (EE), Autonomy Support (AS), and External Focus (EF) during a cycle exercise bout at a simulated altitude of 21,000 feet elevation had an effect on exercise performance and EPOC response in comparison to a control condition.

Methods: Sixteen participants (n = 8 women, n = 8 men) completed resting oxygen measurements (resting metabolic rate) between 6:00 A.M. and 8:00 A.M. Cycle exercise to fatigue at a constant workload was performed (100 W) while breathing air with reduced oxygen content to simulate exercising …

Beyond Genetics: Addressing Activity In Microbial Ecology, Scott Christopher Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of microbial ecology is on the cusp of another revolution, one that uses synergy to address the limitations of previous studies. My dissertation is representative of the new era of research to come, through combining the latest technological advances with established classical methods to provide a more complete understanding of microbial ecosystems. In my first study, I evaluate the conservation of central carbon metabolic pathways and activity along a temperature and diversity gradient (60-95 ℃) through the use of 16S rRNA gene amplicon data, metagenome sequencing, and position-specific 13C-labeled metabolite probing. In my second study, I provide the …

The Ruins Of Doves, Mariah Tahera Yusofzei

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Ruins of Doves is a collection of 40 poems that attempts to access the conversational space for the poet’s encounters with her environment, and correspondingly, with the divine. Keeping with this sentiment, each poem embodies a little song or prayer, where the poem itself acts as a gateway in attempting to understand the divine. Amid the quietness in the space of the poem is where the poet explores her relationship with the divine. An understanding of community, domestic love, and intimacy share a point of arrival where many of the poems begin. Each poem is an accumulation and a …
