Visual Attention to Radar Displays

A model is described which predicts the allocation of attention to the features of a radar display. It uses the growth of uncertainty and the probability of near collision to call the eye to a feature of the display. The main source of uncertainty is forgetting following a fixation, which is modelled as a two dimensional diffusion process. The model was used to predict information overload in intercept controllers, and preliminary validation obtained by recording eye movements of intercept controllers in simulated and live (practice) interception

Development, characterization, and deployment of a high-resolution time-of-flight chemical ionization mass spectrometer (HR-TOF-CIMS) for the detection of carboxylic acids and trace-gas species in the troposphere

Includes bibliographical references.2016 Summer.A historical account of the advances leading to modern high-resolution time-of-flight chemical ionization mass spectrometers (HR-TOF-CIMS) for gas-phase measurements is presented. Recent literature detailing the description of the HR-TOF-CIMS is critically evaluated and put into the context of the historical literature. The development of the HR-TOF-CIMS with reagent ion switching capabilities in the negative mode (acetate and iodide reagent ions), and a novel, low-pressure high-flow inlet with online calibration system is shown to work well in the field. Findings from the deployment of this measurement system during the 2013 Southern Oxidant and Aerosol Study are discussed. Subsequent work with voltage scanning methodologies for controlling cluster transmission is presented and applied to potential aerosol mass chamber experiments examining the oxidation of alpha-pinene. The applicability of acetate chemical ionization to the direct headspace analysis of beer samples is presented. Lastly, the future directions of acetate chemical ionization and voltage scanning are discussed in relation to numerous recent developments related to both gas-phase measurements and new particle formation

Tactical Missile Design at The Naval Postgraduate School

The article of record as published may be found at http://dx.doi.org/10.2514/6.2010-911410th AIAA Aviation Technology, Integration, and Operations (ATIO) ConferenceA Tactical Missile Track has been an available academic track at The Naval Postgraduate School for nearly three decades. The coursework associated with the track can be taken over a one-year period leading to a masters degree in Mechanical and Aerospace engineering and culminates with tactical missile design as the capstone course. The capstone design course often includes the participation of an industry representative to provide the students with a real-world “system integration” point of view and advise the students throughout the design process. The coursework leading up to the design course consists of fundamental “core” courses that apply to nearly all missile systems as well as a wide range of technical electives ranging from campaign analysis to warhead design and effectiveness. A brief history of the Tactical Missile Track is provided and details associated with the available electives are also presented and discussed to show some of the unique feature of Tactical Missile Design at The Naval Postgraduate School. Finally, examples of past design efforts are also presented

Entrepreneurial Competencies in Action: Online Fundraising Initiatives by University Students

It has been argued that entrepreneurship educators are inclined to let students learn in a safe controlled environment, with no pressure except to pass the module. Students working in groups of three were given 12 weeks (Target 1) to develop a fundraising initiative, work with various stakeholders, and execute their online fundraising initiative to meet a target goal of €2000 (Target 2) per group. Employing approaches such as Effectuation, Lean Start-Up and the Business Model Canvas, a self-directed learning approach ensured students were able to take ownership of their learning journey with the lecturer acting as coach or facilitator. The learning innovation stems from the highly experiential nature of the assignment, the various deadlines and targets that had to be met throughout the process, the promoted collaboration with real world environments, the introduction of mentors and other support actors, and the successful adaptation of the assignment to an online learning environment. The assignment can be undertaken in an online or offline environment, and it provides a highly practical learning experience that enables students to utilize and develop the 15 entrepreneurship competencies identified in the EntreComp framework under the pressure of meeting time and monetary targets

An Epidemiological Study of Anemia and Renal Dysfunction in Patients Admitted to ICUs across the United States

The aims of this study were to determine the associations between anemia of critical illness, erythropoietin stimulating agents (ESA), packed red blood cell transfusions and varying degrees of renal dysfunction with mortality, and ICU- and hospital length of stay (LOS). This was a cross-sectional retrospective study of 5,314 ICU patients from USA hospitals. Hospital, patient demographics, and clinical characteristics were collected. Predictors of mortality and hospital and ICU LOS were evaluated using multivariate logistic regression models. The mean ICU admission hemoglobin in this study was 9.4 g/dL. The prevalence of ESA use was 13% and was associated with declining renal function; 26% of the ICU patients in this study received transfusion. ESA utilization was associated with 28% longer hospital LOS (). ICU LOS was increased by up to 18% in patients with eGFR rates of \u3c30 and 30–59 mL/min/1.73 m2, respectively () but not in those receiving dialysis. Mortality was significantly associated with renal dysfunction and dialysis with odds ratios of 1.94, 2.66 and 1.40 for the dialysis, and eGFR rates of \u3c30 and 30–59 and mL/min/1.73 m2, respectively (). These data provide a snapshot of anemia treatment practices and outcomes in USA ICU patients with varying degrees of renal dysfunction
