Interpolation algorithms and image data artifacts

Interpolation, or resampling coefficients, which are generated from low pass filter Fourier transforms yield more accurate resampled values than those obtained using cubic spline techniques. This is due to the utilization of six data points rather than four as currently used in cubic spline analysis. After resampling functions are applied to image data, artifacts which are similar to ringing may become pronounced. These effects are often present in the original data and the interpolation merely enhances them

Detection of ocean color changes from high altitudes

The detection of ocean color changes, thought to be due to chlorophyll concentrations and gelbstoffe variations, is attempted from high altitude (11.3km) and low altitude (0.3km). The atmospheric back scattering is shown to reduce contrast, but not sufficiently to obscure color change detection at high altitudes

Gas flows in elliptical galaxies

In preparation for the next generation of x ray telescopes, researchers have begun a program investigating the evolving x ray properties of elliptical galaxies. Their galaxy models consist of a modified King profile for the luminous portion of the galaxy and can include an isothermal dark halo comprising 90 percent of the total mass. The stellar population is assumed to form at a rate which decreases exponentially on a dynamical time scale with a Salpeter initial mass function. Stellar mass loss occurs instantaneously as stars evolve off the main sequence. All stars more massive than 8 solar mass produce type II supernovae, while less massive stars loss mass through a planetary nebulae. The evolving rate of type I supernovae is normalized to a fraction, gamma sub sn I, of Tammann's (1974) value. All of this information is then incorporated into a one-dimensional hydrodynamics code to determine the evolving dynamical state of the interstellar medium

Mobile Video Monitoring to Reduce Falls and Sitter Usage

In the United States between 700,000 to 1,000,000 people fall in hospitals each year. Reducing patient falls in the inpatient setting remains a challenge for many acute care hospitals. Inpatient falls can lead to serious injuries such as fractures and internal bleeding. Fall-related complications can lead to increased hospital stay, prolonged rehabilitation, and increased healthcare costs. Inpatient falls are considered preventable. One intervention commonly used to prevent falls and keep patients safe is the use of an in-person sitter or a patient safety companion (PSC). However, sitters are very costly and considered a variable staffing resource. The need for a sitter can be difficult to predict and adequately staff. Many organizations are looking for ways to reduce sitter usage and costs. Research suggests reducing sitter use does not negatively influence patient fall rates and fall with injury rates. An alternative solution to reduce sitter usage is mobile video monitoring. Mobile video monitoring is an innovative tool that has been shown to significantly reduce healthcare cost and reduce patient falls and falls with injury. The purpose of this project was to implement mobile video monitoring to decrease fall incidences, fall with injury incidences, and decrease sitter usage and costs. Demographic data, sitter hours, falls, and fall with injury incidences were collected. Results indicated no significant difference in falls and falls with injury with use of mobile video monitoring versus an in-person sitter. Sitter hours and sitter costs decreased with use of mobile video monitoring during the 44 day pilot

The Voices from the Sanctuary: The Female Narrators of J M Coetzee\u27s In the Heart of the Country and Doris Lessing\u27s Memoirs of a Survivor

In both In the Heart of the Country (1977) by J. M. Coetzee and The Memoirs of a Survivor (1974) by Doris Lessing, a female narrator fabricates a sanctuary—mental rather than physical—that enables each woman to challenge, deflect, or adapt to a conflict and that shelters her from a hostile, patriarchal society. For Coetzee\u27s narrator (Magda) in In the Heart of the Country, writing, rewriting, and editing provide the necessary devices to establish her asylum in her quest for identity. For Lessing\u27s narrator (the survivor) in The Memoirs of a Survivor, escaping behind the wall allows her to find refuge from and to bring order to a rapidly disintegrating society. Because the relationship between the author and narrator in these two novels influences the development of these particular features and characteristics of each narrator, an examination of voice provides evidence that the gender of the author does indeed affect the development of the narrators, evident primarily in the images of time and the engendered perceptions of the narrators. Magda writes from the masculine perspective; her voice represents the male-dominated world of Coetzee controlling the situation from a position of power. A dominant first person I helps the reader view her not simply as a spinster in the middle of nowhere, but rather as a member of the patriarchal system found in the outside world. In the situation of Lessing\u27s survivor, her feminine perspective and feminine empowerment project a strong woman who makes the transition from a patriarchal outside world to a matriarchal world behind the wall. Her actions behind the wall show an acceptance of the past and the present, but also a projection of a better future when dealing with both environments. Without this particular attitude and exacting strength, the survivor could not have successfully moved into the world of the wall. This feminine perspective and empowerment influence her writing style and require the inclusion of others\u27 stories. The shelters fabricated by the narrators, examined in the second section of the paper, are defined by the nature of the spatial dimensions (figurative and literal) of the sanctuaries. This concept of sanctuary evolves from writings about ancient Greek cities in which sanctuaries represent places of asylum and refuge. The narrators\u27 sanctuaries are discussed in terms of an asylum for Magda and a refuge for the survivor. Magda establishes an asylum to adapt to her masculine fight against nature, evidenced by the voice she employs to deal with the outside world. In contrast to Magda\u27s mental asylum, the corporeal nature of the refuge behind the wall represents the unity of the survivor\u27s joining of feminine perception and feminine power. Within the two novels, the personalities, actions, thoughts, relationships, decisions, writing style, voice, and construction of the sanctuaries must be understood within the framework of the perspective and empowerment afforded the narrators by their authors
