Spread and SpreadRecorder An Architecture for Data Distribution

The Space Acceleration Measurement System (SAMS) project at the NASA Glenn Research Center (GRC) has been measuring the microgravity environment of the space shuttle, the International Space Station, MIR, sounding rockets, drop towers, and aircraft since 1991. The Principle Investigator Microgravity Services (PIMS) project at NASA GRC has been collecting, analyzing, reducing, and disseminating over 3 terabytes of collected SAMS and other microgravity sensor data to scientists so they can understand the disturbances that affect their microgravity science experiments. The years of experience with space flight data generation, telemetry, operations, analysis, and distribution give the SAMS/ PIMS team a unique perspective on space data systems. In 2005, the SAMS/PIMS team was asked to look into generalizing their data system and combining it with the nascent medical instrumentation data systems being proposed for ISS and beyond, specifically the Medical Computer Interface Adapter (MCIA) project. The SpreadRecorder software is a prototype system developed by SAMS/PIMS to explore ways of meeting the needs of both the medical and microgravity measurement communities. It is hoped that the system is general enough to be used for many other purposes

Spotlight-8 Image Analysis Software

Spotlight is a cross-platform GUI-based software package designed to perform image analysis on sequences of images generated by combustion and fluid physics experiments run in a microgravity environment. Spotlight can perform analysis on a single image in an interactive mode or perform analysis on a sequence of images in an automated fashion. Image processing operations can be employed to enhance the image before various statistics and measurement operations are performed. An arbitrarily large number of objects can be analyzed simultaneously with independent areas of interest. Spotlight saves results in a text file that can be imported into other programs for graphing or further analysis. Spotlight can be run on Microsoft Windows, Linux, and Apple OS X platforms

Bacteriology of Hemodialysis Fluids: Are Current Practices Meaningful?

A report submitted by Ted Pass to the Research and Creative Productions Committee on September 25, 1990 on the current practices for monitoring bacterial contamination of fluids employed in the preparation and execution of hemodialysis therapy

Color Image Processing and Object Tracking System

This report describes a personal computer based system for automatic and semiautomatic tracking of objects on film or video tape, developed to meet the needs of the Microgravity Combustion and Fluids Science Research Programs at the NASA Lewis Research Center. The system consists of individual hardware components working under computer control to achieve a high degree of automation. The most important hardware components include 16-mm and 35-mm film transports, a high resolution digital camera mounted on a x-y-z micro-positioning stage, an S-VHS tapedeck, an Hi8 tapedeck, video laserdisk, and a framegrabber. All of the image input devices are remotely controlled by a computer. Software was developed to integrate the overall operation of the system including device frame incrementation, grabbing of image frames, image processing of the object's neighborhood, locating the position of the object being tracked, and storing the coordinates in a file. This process is performed repeatedly until the last frame is reached. Several different tracking methods are supported. To illustrate the process, two representative applications of the system are described. These applications represent typical uses of the system and include tracking the propagation of a flame front and tracking the movement of a liquid-gas interface with extremely poor visibility

Student empathy levels across 12 medical and health professions: an interventional study

BackgroundEmpathy is a difficult characteristic to define, teach and assess; the &lsquo;nebulous&rsquo; properties of empathic behaviour often means that educators fail to incorporate the explicit teaching and assessment of empathy within the curriculum. One solution suggested is that teaching empathy in an interprofessional education setting is an effective educational approach in developing empathic behaviours.MethodStudent participants from Monash University, Deakin University, University of South Australia, and Edith Cowan University completed a self-reporting survey package pre and post two-hour empathy workshop consisting of the Jefferson Scale of Empathy &ndash; Health Profession &ndash; Student version (JSE-HP-S).ResultsA total of 293 students from 12 different medical and health care professions participated in the empathy workshops. The majority of participants were from Monash University n&thinsp;=&thinsp;230 (78 %), the nursing profession n&thinsp;=&thinsp;59 (20 %), &lt; 26 years of age n&thinsp;=&thinsp;215 (73 %) and enrolled in first year studies n&thinsp;=&thinsp;123 (42 %). Using a paired t-test repeated measure self-reported empathy levels improved at p&thinsp;&lt;&thinsp;0.0001, mean 114.34 vs. 120.32 (d&thinsp;=&thinsp;0.22).ConclusionThis project has shown that self-reported empathy levels have been shown to statistically improve following DVD simulation-based workshops.<br /
