The Digital Library (DL) field is one of the most promising areas of application for information visualization technology. In this paper, we propose a visual user interface tool kit for digital libraries, to deliver an overview of document sets, with support for interactive direct manipulation. Our system, Citiviz, employs a dynamic hyperbolic tree to display hierarchical relationships among do...

PURPOSE To test the hypothesis that an individual shows concordance of aqueous humor flow in the morning and at night in a prospective inpatient fluorophotometry study in healthy subjects. METHODS Flow was measured in each eye every hour between 8 AM and noon and every 2 hours between midnight and 6 AM. Morning and nighttime flows were analyzed for differences between eyes and for differences...

introduction: the key characteristics of positron emission tomography (pet) are its quantitative capability and its sensitivity, which allow the in vivo imaging of biochemical interactions with small amounts of tracer concentrations. therefore, accurate quantification is important. however, it can be sensitive to several physical factors. the aim of this investigation is the assessment of the e...

In visual data exploration with scatter plots, no single plot is sufficient to analyze complicated high-dimensional data sets. Given numerous visualizations created with different features or methods, meta-visualization is needed to analyze the visualizations together. We solve how to arrange numerous visualizations onto a meta-visualization display, so that their similarities and differences c...

Projecfing multidimensional data to a lower-dimensional visual displayas a scatter-plot-llke visualization is a common approach for analyzing mullidimensional data. Many dimension reduclion techniques existfor performing such a tasle, but the quallty of projections varies in terms of both preserving the original data structure and avoiding cluttered visual displays. In this papel; we propose an...

Visualizations provide a natural means for organizing large complex data sets and mining them for characteristics of interest. In this paper, we describe SPLAT, a scatter and phase plot animation tool. SPLAT offers a broad set of capabilities for investigating Internet measurement data sets based on scatter and phase plots—two well-known techniques for exploratory data analysis. An important fe...

This paper proposes the usage of visualisation widgets for exploratory search with sentiment as a facet. Starting from specific design goals for depiction of ambivalence in sentiment, two visualization widgets were implemented: scatter plot and parallel coordinates. Those widgets were evaluated against a text baseline in a small-scale usability study with exploratory tasks using Wikipedia as da...

Most of the 3D printing applications of preoperative models have been focused on dental and craniomaxillofacial area. The purpose of this paper is to demonstrate the possibilities in other application areas and give examples of the current possibilities. The approach was to communicate with the surgeons with different fields about their needs related preoperative models and try to produce preop...

Despite the increasing popularity of 3D printing, also known as additive manufacturing (AM), the technique has not developed beyond the realm of rapid prototyping. This confinement of the field can be attributed to the inherent flaws of layer-by-layer printing and, in particular, anisotropic mechanical properties that depend on print direction, visible by the staircasing surface finish effect. ...
