Using high resolution displays for high resolution cardiac data

The ability to perform fast, accurate, high resolution visualization is fundamental to improving our understanding of anatomical data. As the volumes of data increase from improvements in scanning technology, the methods applied to rendering and visualization must evolve. In this paper we address the interactive display of data from high resolution MRI scanning of a rabbit heart and subsequent histological imaging. We describe a visualization environment involving a tiled LCD panel display wall and associated software which provide an interactive and intuitive user interface. The oView software is an OpenGL application which is written for the VRJuggler environment. This environment abstracts displays and devices away from the application itself, aiding portability between different systems, from desktop PCs to multi-tiled display walls. Portability between display walls has been demonstrated through its use on walls at both Leeds and Oxford Universities. We discuss important factors to be considered for interactive 2D display of large 3D datasets, including the use of intuitive input devices and level of detail aspects

A study of spatial data management and analysis systems

The Earth Resources Laboratory of the NASA Stennis Space Center is a center of space related technology for Earth observations. It has assumed the task, in a joint effort with Jackson State University, to reach out to the science community and acquire information pertaining to characteristics of spatially oriented data processing

Space human factors discipline science plan

The purpose of this Discipline Science Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the comprehensive areas of behavior, performance, and human factors. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, defines critical questions in the subdiscipline areas, and identifies technological priorities. It covers the significant research areas critical to NASA's programmatic requirements for the Extended Duration Orbiter, Space Station Freedom, and Exploration mission science activities. These science activities include ground-based and flight; basic, applied and operational; and animal and human research and development. This document contains a general plan that will be used by both NASA Headquarters program offices and the field centers to review and plan basic, applied, and operational research and development activities, both intramural and extramural, in this area

VISUAL MOUSE (COLOR TRACKING)

This Final Year Project is about Visual Mouse (Color tracking). This project will demonstrates how a webcam could be used to track objects in front of it and track hand movements to drawon the computer. It is applicable for paper presentations and lectures. This project will deal with algorithm and tools in MATLAB software as its medium. The basic principle of this project would be distinguishing color and use its properties to move a cursor in MATLAB and draw as well

Legal Problems of Computer Abuse

Computer abuse consists of incidents caused by intentional acts from which a perpetrator realized or could have realized a gain and/or a victim suffered or could have suffered a loss. In this Article, Susan Hubbell Nycum discusses a wide variety of criminal acts relating to computers and notes that, because of the unique nature of the computer itself, these acts do not fit within traditional criminal classifications. Reform at both the state and federal levels is necessary if the law is to provide adequate protection for computer hardware and software users. The accelerating, almost uncontrolled increase in computer use affects the court system as well. The material presented herein is based on a multi-year study supported in part by the National Science Foundation. The study now includes an analysis of over 500 reported incidents of computer abuse

Factors that impact on the effectiveness of professional development programs for science teachers in Saudi Arabia

The Saudi Arabian Government has made a substantial investment in reforming the science curriculum in Saudi Arabia. The need for effective professional development (PD) programs is especially crucial in the context of recent curriculum reform in Saudi Arabia. The country has adopted new science curricula following the guidelines of renowned global publishers like McGraw-Hill. However, the introduction of the new science curriculum is posing challenges for science teachers, as it requires a paradigm shift from a teacher-centred to a learner-centred pedagogy. The research for this research involved an in-depth study on the impact of mandatory PD programs on Saudi Arabian science teachers in order to identify potential challenges to achieving the expected level of benefit from the PD programs. This study used a qualitative approach to data collection techniques. through employs three main methods for data collection, observation ,open-ended questionnaire and interview. the most effective professional development programs are likely to be those that address the specific subject matter that relates to the teaching issues faced daily by teachers, rather than those that cover vague and decontextualised educational or pedagogical concepts. Other factors include teachers’ involvement in learning communities, the facilities and resources provided by the school, and individual learning styles. On the other hand, common factor responsible for the failure of professional development programs is that the content covered is not relevant to the teachers’ specific needs. PD programs in Saudi Arabia are mainly focused on quantity instead of quality
