Effect of Simulation on Interprofessional Communication and Collaboration for Nurses in China

Description

Nurses working in China do not have access to hospital data, access to professional organizations, or to the internet for reviewing evidence-based practice (EBP). Chinese healthcare organizational leaders are seeking

Nurses working in China do not have access to hospital data, access to professional organizations, or to the internet for reviewing evidence-based practice (EBP). Chinese healthcare organizational leaders are seeking international support to provide nurse leaders with necessary skills to lead China based organizations in safe, quality, healthcare delivery.

With the opening of a new hospital in Yinchuan, China, it is imperative to ensure that a climate of collaboration, teamwork, and clear communication methods exist between nurses, doctors, and other interprofessional staff members. Evidence indicates that use of simulation with standardized communication tools and processes (use of Situation-Background- Assessment-Recommendation [SBAR], TeamSTEPPS, and checklists) can facilitate interprofessional collaboration and teamwork and improve communication among interprofessional staff. Designing effective simulation scenarios with sensitivity to Chinese culture, with an interprofessional staff will enhance quality and patient safety in Chinese hospitals.

The intention of this report is to use computer simulations to investigate the viability of two materials, water and polyethylene, as shielding against space radiation. First, this thesis discusses some of the challenges facing future and current manned space missions as a result of galactic cosmic radiation, or GCR. The project then uses MULASSIS, a Geant4 based radiation simulation tool, to analyze the effectiveness of water and polyethylene based radiation shields against proton radiation with an initial energy of 1 GeV. This specific spectrum of radiation is selected because it a component of GCR that has been shown by previous literature to pose a significant threat to humans on board spacecraft. The analysis of each material indicated that both would have to be several meters thick to adequately protect crew against the simulated radiation over a several year mission. Additionally, an analysis of the mass of a simple spacecraft model with different shield thicknesses showed that the mass would increase significantly with internal space. Thus, using either material as a shield would be expensive as a result of the cost of lifting a large amount of mass into orbit.

Thermal Analysis of Preliminary Design of Pulsed Plasma Thruster for Multi-Axis CubeSat Attitude Control Applications

Description

Smallsats such as CubeSats have a variety of growing applications in low Earth orbit (LEO), near Earth orbit (NEO), and deep space environments across communications, imaging, and more. Such applications have tight pointing requirements and thus an accompanying need for attitude control systems (ACS) with finer pointing capabilities and longer lifetimes. Current systems such as magnetorquers and reaction wheels have notable limitations. Magnetorquers lose applicability for many deep space applications while the latter is dependent on moving components and cannot be operated independently due to momentum saturation among other limitations. Micro-Pulsed Plasma Thrusters (μPPTs) can be designed for multi-axis control in space. The use of solid Teflon (PTFE) propellant to produce a controllably small impulse within the thrusters can enable increased fine pointing accuracy and precision. In this paper, a preliminary design of an 8-thruster set of breech-fed μPPTs is analyzed through mechanical simulation tools to address challenges posed by miniaturization into a 1U module. Mechanical challenges of miniaturizing a μPPT module are particularly driven by the volume constraint and the associated appropriate mass. Thermal analysis performed using C&R Thermal Desktop, addresses the thermal environment for various use cases, individual component heating, as well as heat transfer through the module. This directly informs component layout recommendations and thermal controls based upon maintaining operational temperature ranges for various use cases. This model as well as fabrication considerations inform material selections for various structures in the preliminary μPPT design. In this paper I will discuss the overall design of the PPT model that has been configured here at Arizona State University by the Sun Devil Satellite Laboratory. I will then discuss the findings of my thermal analysis that was performed using Thermal Desktop.

In this project, we created a code that was able to simulate the dynamics of a three site Hubbard model ring connected to an infinite dissipative bath and driven by an electric field. We utilized the master equation approach, which will one day be able to be implemented efficiently on a quantum computer. For now we used classical computing to model one of the simplest nontrivial driven dissipative systems. This will serve as a verification of the master equation method and a baseline to test against when we are able to implement it on a quantum computer. For this report, we will mainly focus on classifying the DC component of the current around our ring. We notice several expected characteristics of this DC current including an inverse square tail at large values of the electric field and a linear response region at small values of the electric field.

Agriculture is the second largest water consumer in the Phoenix Metropolitan region, after the municipal sector. A significant portion of the cultivated land and agricultural water demand is from the production of animal feed, including alfalfa (~69% of total cropland area), corn (~8), and sorghum (-3%), which are both exported and needed to support local dairy industry. The goal of this thesis is to evaluate the impacts on water demand and crop production of four different crop portfolios using alfalfa, corn, sorghum, and feed barley. For this aim, the Water Evaluation And Planning (WEAP) platform and the embedded MABIA agronomic module are applied to the Phoenix Active Management Area (AMA), a political/hydrological region including most of Phoenix Metro. The simulations indicate that the most efficient solution is a portfolio where all study crop production is made up by sorghum, with an increase of 153% in crop yield and a reduction of 60% of water consumption compared to current conditions. In contrast, a portfolio where all study crop production is made up by alfalfa, which is primary crop grown in current conditions, decreased crop yield by 77% and increases water demand by 105%. Solutions where all study crop production is achieved with corn or feed barley lead to a reduction of 77% and 65% of each respective water demand, with a portfolio of all corn for study crop production increasing crop yield by 245% and a portfolio of all feed barley for study crop production reducing crop yield by 29%.

Covid-19 is unlike any coronavirus we have seen before, characterized mostly by the ease with which it spreads. This analysis utilizes an SEIR model built to accommodate various populations to understand how different testing and infection rates may affect hospitalization and death. This analysis finds that infection rates have a significant impact on Covid-19 impact regardless of the population whereas the impact that testing rates have in this simulation is not as pronounced. Thus, policy-makers should focus on decreasing infection rates through targeted lockdowns and vaccine rollout to contain the virus, and decrease its spread.

High-entropy alloys possessing mechanical, chemical, and electrical properties that far exceed those of conventional alloys have the potential to make a significant impact on many areas of engineering. Identifying element combinations and configurations to form these alloys, however, is a difficult, time-consuming, computationally intensive task. Machine learning has revolutionized many different fields due to its ability to generalize well to different problems and produce computationally efficient, accurate predictions regarding the system of interest. In this thesis, we demonstrate the effectiveness of machine learning models applied to toy cases representative of simplified physics that are relevant to high-entropy alloy simulation. We show these models are effective at learning nonlinear dynamics for single and multi-particle cases and that more work is needed to accurately represent complex cases in which the system dynamics are chaotic. This thesis serves as a demonstration of the potential benefits of machine learning applied to high-entropy alloy simulations to generate fast, accurate predictions of nonlinear dynamics.

Information technology has become an increasing popular major offered by various universities, and provides the student with notable flexibility regarding courses as there are multiple career paths to suit the person’s specific technical interests. However, the methods universities use to promote their majors, including IT, are not as effective as it needs to be. The mediums currently used are mostly comprised of brochures, flyers, a single web page from the university’s entire website, and some communication with advisors, among others. This can be an issue for many readers as the information is often brief, providing only summaries of what can be expected, and ambiguous statistics that may not accurately or completely reflect the prospects of graduates looking to make a living the rest of their adult lives. This could cause some students to choose a major that may not be their best fit, and changing majors later will be very costly and delay graduation by one or more years. Therefore, the advocation of majors will have be rethought. The IT major offered at ASU is a perfect opportunity to determine whether a major can be promoted through a different approach with a senior capstone project involving a website. This Barrett creative project will act as a subset of the capstone project that will explore an attempt at introducing in interactive element to the website that allows prospective students to get a brief introduction to the computer networking aspect of IT, which includes a real world introductory game, along with more detailed exercises if the user is interested.
