Background: Presenting results of diagnostic test accuracy research so that it is accessible to users is challenging. Commonly used accuracy measures (e.g. sensitivity and specificity) are poorly understood by health professionals and the public. Evidence suggests that presenting probabilities as natural frequencies rather than percentages facilitates understanding. We present a test consequenc...

Textual information can be sent as graphic images without being coded in the broadband digital network. By using graphic text, characters or symbols with unsupported fonts can be displayed. Graphical e-mail systems in mobile phones for sending digital photographs are useful in sending graphic text. We researched the visibility of graphic text on the liquid crystal displays in mobile phones comp...

v9fb is a software infrastructure that allows extending framebuffer devices in Linux over the network by providing an abstraction to them in the form of a filesystem hierarchy. Framebuffer based graphic devices export a synthetic filesystem which offers a simple and easy-to-use interface for performing common framebuffer operations. Remote framebuffer devices could be accessed over the network ...

Spatial disparity between a physical object and its visual presentation is very common in virtual environments. An experiment was conducted to systematically investigate the effects of orientation disparity between haptic and graphic displays of objects on human performance in a virtual environment. It was found that human performance was optimum with no orientation disparity. Orientation dispa...

Graphic methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subjective and objective uncertainty display methods are presented, including qualitative assessments, node and arrow diagrams, standard statistical me...

This document is intended to help people without formal training in map design learn to produce maps for publication or electronic display using ArcView, a desktop geographic information system (GIS). A GIS is a system for the display, analysis, storage and retrieval of information about places on the earth. GIS is a useful tool for exploring information and communicating your discoveries to ot...

During normal viewing of an object, a human observer will typically make small movements in the position of the head resulting in small parallax-related image changes. The significance of these changes is apparent when viewing a static stereographic display. Since the observer expects modifications in viewing direction that accompany side to side head movements, the lack of such changes in view...

The key techniques of intelligent analysis instrument developed are proposed. Based on the technique of virtual instrumentation, the intelligent PID control algorithm to control the temperature of thermal analysis instrument is described. The dynamic character and the robust performance of traditional PID controls are improved through the dynamic gain factor, temperature rate change factor, the...

This paper presents the strategy for multi-criteria optimization of a prototype. There are taken into account two different optimization criteria. An original computer program was made to make possible the graphic display of regions on the 3D model surface, which exceed a limit for surface roughness, initial established. The computer program allows the automate calculation of optimal position f...
