Anesthesia Clinical Core Competencies And High Fidelity Human Simulation, Jeffrey Colby James

Doctoral Dissertations

The purpose of the study was to identify anesthesia clinical core competencies that are appropriate for evaluating proficiency utilizing High Fidelity Human Simulation (HFHS). This purpose was achieved by identifying the perceptions of nurse anesthesia educational program administrators and faculty regarding the anesthesia clinical core competencies that are appropriate for evaluating proficiency utilizing HFHS. Participants completed a 50-item web-based survey instrument and demographic questionnaire (Anesthesia Core Competency and Simulation Survey). High fidelity human simulation (HFHS) based evaluation of anesthesia clinical core competency proficiency can be a valuable tool for assessing anesthesia trainees, certifying nurse anesthetists, and recertifying nurse anesthetists. Evidence …

Computing Approximate Solutions To The Art Gallery Problem And Watchman Route Problem By Means Of Photon Mapping, Bruce Andrew Johnson

Doctoral Dissertations

Wireless sensor networks (WSNs) can be partitioned component sensor nodes (SNs) who are meant to operate and sense information arriving from multiple spectra in their environment. Determining where to place a single SN or multiple SNs such that the amount of information gained is maximized while the number of SNs used to gain that information is minimized is an instance of solving the art gallery problem (AGP). In order to solve the AGP, we present the Sensor Placement Optimization via Queries (SPOQ) algorithm that uses level sets populated by queries to a photon map in order to find observation points …

Parallel Multi-Core Verilog Hdl Simulation, Tariq B. Ahmad

Doctoral Dissertations

In the era of multi-core computing, the push for creating true parallel applications that can run on individual CPUs is on the rise. Application of parallel discrete event simulation (PDES) to hardware design verification looks promising, given the complexity of today’s hardware designs. Unfortunately, the challenges imposed by lack of inherent parallelism, suboptimal design partitioning, synchronization and communication overhead, and load balancing, render this approach largely ineffective. This thesis presents three techniques for accelerating simulation at three levels of abstraction namely, RTL, functional gate-level (zero-delay) and gate-level timing. We review contemporary solutions and then propose new ways of speeding up …

An Evidence-Based Educational Intervention For Staff Nurses And The Rapid Response Team, Grace Katherine Gembrowski

Doctoral Dissertations

Rapid response systems (RRSs) have been proven to decease mortality, cardiac arrests, and ICU admissions. The three major health care system issues lead to failure to rescue: failure to communicate, failure to plan, and failure to recognize deteriorating conditions. It is crucial in a hospital setting that nurses have a basic knowledge base of why, when, and how the RRS should be activated as they are the first line of defense to recognizing signs of deterioration in patients. Previous research has shown that, although signs of patient deterioration are seen by staff, they are not always acted upon (Pusateri et …

Numerical Simulation Of Hydrogen Absorption/Desorption Processes In Cylindrical Metal-Hydrogen Reactors For Hydrogen Storage, Fei Han

Doctoral Dissertations

Hydrogen is one of the best fuels because of its high calorific value and environmental friendliness. However, because of its low density, it has storage problems such as high pressure, large volume requirements, heavy weight and safely risks; this quality prevents its wide usage and commercialization.

Researchers have found that some metal/inter-metallic compounds/alloys, such as Mg, La, LaNi5, ZrV2, Mg2Ni and Ti 2Ni, can react with hydrogen and attain relatively large amounts of hydrogen at a relatively low pressure and near normal temperature. Under certain conditions, hydride can desorb hydrogen quickly. Thus, the metal- hydrogen reaction could be a practical …
