This paper presents the modules in the statistical package ViSta related to categorical data analysis. These modules are: visualization of frequency data with mosaic and bar plots, correspondence analysis, multiple correspondence analysis and loglinear analysis. All these methods are implemented in ViSta with a big emphasis on plots and graphical representations of data, as well as interactivit...

We have developed an application of a full-body, noncontact gesture interface for exploring cyberspace that provides immersive walk-through and information accessing capabilities. The VisTA-walk system is designed for use at the museum exhibitions where easy, durable, and pleasurable user interface is preferable. It uses a large projection screen for immersive cyberspace presentation. VisTA-wal...

In these proceedings I discuss various extragalactic surveys which will be undertaken over the next few years and which will be complementary to any HI and/or continuum surveys with the SKA-precursor telescopes. I concentrate on the near-infrared public surveys which will be undertaken with the Visible and Infrared Survey Telscope for Astronomy (VISTA), and in particular the VISTA Deep Extragal...

This paper presents the functionality of the Visual Interactive System for Transportation Algorithms (VISTA) that utilizes a mesoscopic/microscopic simulation called RouteSim and a Dynamic Traffic Assignment (DTA) routine to emulate the behavior of individual drivers and how they distribute themselves into the transportation network. The principal output of the model is the path chosen by every...

Suppose an observer views a distant object through a window in the far wall of a room or corridor--a visual scene constituting a vista. If the observer moves toward the window, then the distant object will shrink in apparent size and appear farther away. These effects are paradoxical, because the distant object appears smaller as its visual angle increases. The vista paradox occurs under many o...

The Vista instrument has a number of distinct advantages over similar ICP-OES systems. Firstly, the VistaChip is the only single Charge Coupled Device (CCD) that allows full coverage of the spectrum from 165-785nm, with a pixel processing speed of 1 MHz and exceptional anti-blooming properties. These features allow both trace level analytes and major analytes to be determined in the same measur...

BACKGROUND Hemolysis, icterus, and lipemia (HIL) cause preanalytical interference and vary unpredictably with different analytical equipments and measurement methods. We developed an integrated reporting system for verifying HIL status in order to identify the extent of interference by HIL on clinical chemistry results. METHODS HIL interference data from 30 chemical analytes were provided by ...

MOTIVATION The power of multi-sequence comparison for biological discovery is well established. The need for new capabilities to visualize and compare cross-species alignment data is intensified by the growing number of genomic sequence datasets being generated for an ever-increasing number of organisms. To be efficient these visualization algorithms must support the ability to accommodate cons...

BACKGROUND There are few studies for evaluating plaque characteristics of nonstenotic basilar arteries (BA). Our aim was to determine entire BA plaques with a three-dimensional volumetric isotropic turbo spin-echo acquisition (VISTA) and investigate the differences between the patients with and without isolated pontine infarction (IPI). METHODS Twenty-four consecutive symptomatic patients wit...
