Exploratory visual analytics for the european single intra-day coupled electricity market

European single intra-day coupled electricity market (SIDC) trading activity has increased substantially in recent years mainly as a consequence of the increasing penetration of renewable energy production and its subsequent impact on imbalance market prices. Nonetheless, more research is needed to understand this growing market. This paper...

Enhanced Spatial Stability with Hilbert and Moore treemaps

Abstract—Treemaps are a well known and powerful space-filling visualisation method for displaying hierarchical data. Many alternative treemap algorithms have been proposed, often with the aim being to optimise performance across several criteria, including spatial stability to assist users in locating and monitoring items of interest. In this...

Hyperspectral Data Analysis and Visualisation

Electro-Optical (EO) imaging sensors are widely used for a range of tasks, e.g. for Target Acquisition (TA: detection, recognition and identification of (military) relevant objects) or visual search. These tasks can be performed by a human observer, by an algorithm (Automatic Target Recognition) or by both (Aided Target Recognition). In the past...

Analyse van sociale media

Het gebruik van sociale media overtreft al enkele jaren in ruime mate het gebruik van klassieke media als e-mail (Nielsen, 2009). Voor velen is een bestaan zonder Facebook, Flickr, Hyves, MySpace, FourSquare, LinkedIn en Twitter dan ook niet meer denkbaar. Door de sporen die elke gebruiker van sociale media achterlaat in de vorm van berichtjes,...

Thunderstorms in my computer: The effect of visual dynamics and sound in a 3D environment

We assessed the effects of the addition of dynamic visual elements and sounds to a levee patroller training game on the appraisal of the environment and weather conditions, the engagement of the users and their performance. Results show that the combination of visual dynamics and sounds best conveys the impression of severe weather conditions...

Integrating VR and knowledge-based technologies to facilitate the development of operator training systems and scenarios to improve process safety

Process safety can be regarded of paramount importance since any malfunction or mal-operation of a hazardous processing plant may lead to accidents that will cause damage to properties, injury to people and may even result in fatalities. This project investigates how Virtual Reality (VR) and knowledge-based (in particular rule-based)...

Visual interpretation of polarimetric SAR imagery

A study is presented in which several different representations of polarimetric SAR data for visual interpretation are evaluated. Using a group of observers the tasks 'land use classification' and 'object detection' were examined. For the study, polarimetric SAR data were used with a resolution of 3 meters. These data were obtained with the...

Assessment of dermal exposure during airless spray painting using a quantitative visualisation technique

The range of dermal exposure to non-volatile compounds during spray painting was studied in a semi-experimental study involving three enterprises and 12 painters. A fluorescent tracer was added to the paint and deposition of the tracer on clothing and uncovered parts of the skin was assessed using video imaging and processing techniques. A...
