The paper describes a tool designed within the first stage of the European project INVISIP in order to explore geographical metadata in the site planning process. A visual data mining approach is applied to a database of geographical metadata to help the user find an optimal subset of the existing geographical datasets for his particular planning task. It allows the user to perform both confirm...

Brushing teeth is a daily habit to maintain oral hygiene, including the maintenance of oral cleanliness and prevention of caries and periodontal disease. However, tooth brushing is often not carried out correctly or forgotten because the task is boring. Although several works have contributed to improving brushing performance and motivation, the feedback seems to be very remote from the brushin...

In graph cleaning problems, brushes clean a graph by traversing it subject to certain rules. Various problems arise, such as determining the minimum number of brushes that are required to clean the entire graph. This number is called the brushing number. Here, we study a new variant of the brushing problem in which one vertex is cleaned at a time, but more than one brush may traverse a dirty ed...

In this paper we present angular brushing for parallel coordinates (PC) as a new approach to highlighting rational data-properties, i.e., features which – in a non-separable way – depend on two data dimensions. We also demonstrate smooth brushing as an intuitive tool for specifying nonbinary degree-of-interest functions (for focus+context visualization). We also briefly describe our implementat...

The complex structure of longitudinal data with associated discrete covariates requires developing visual methods for a better understanding of underlying structures. In this paper, a simple and flexible method, linked brushing, was studied for such datasets to detect the mean structure. Methods were applied to a random dataset from The Panel Study of Income Dynamics (PSID), which was first use...

As the complexity and amount of real world data continuously grows, modern visualization systems are changing. Traditional information visualization techniques are often not sufficient to allow an in-depth visual data exploration process. Multiple view systems combined with linking & brushing are only one building block of a successful InfoVis system. In this paper we propose the incorporation ...

Visualisations have previously combined linking and brushing operations successfully. However, none to our knowledge have combined linking and focussing techniques. We describe the motivation behind developing such a technique, and show how our visualisation takes advantage of inherent links in a set of multiple overlapping hierarchies to build a mechanism that can produce linked focus + contex...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...
