In this paper the interactive visual simulation environment SEA is presented. SEA supports the embedding of several existing languages that are in use for the speci-cation of heterogeneous systems in diierent application domains (e. g. SDL, data ow graphs, diierential equations). Furthermore, freely deened graphical elements like pictograms can be incorporated. This feature allows system design...

Regulations concerning different modes of transport of dangerous goods are well harmonized at global level: they were then looked at as a model for developing Globally Harmonized System of Classification and Labelling of Chemicals (GHS), (on which CLP Regulations is based). Transport regulations do not cover some hazard classes, such as germ cell mutagenicity, carcinogenicity, reproductive toxi...

In this paper, we propose an unsupervised neural network allowing a robot to learn sensory-motor associations with a delayed reward. The robot task is to learn the \meaning" of pictograms in order to \survive" in a maze. First, we introduce a new neural conditioning rule (PCR: Probabilistic Conditioning Rule) allowing to test hypotheses (associations between visual categories and movements) dur...

Participants at both end of the communication channel must share common pictogram interpretation to communicate. However, because pictogram interpretation can be ambiguous, pictogram communication can sometimes be difficult. To assist human task of selecting pictograms more likely to be interpreted as intended, we propose a semantic relevance measure which calculates how relevant a pictogram is...

The successful development of any geographic information system project needs the careful design and implementation of spatial databases via conceptual and logical data-modeling. This involves understanding the underlying spatial data model, spatial data types and operators, spatial query languages and spatial indexing techniques. Conventional entity-relationship diagrams have limitations for c...

Mobile phone e-mail is increasingly being chosen by consumers as their primary communication tool. Messages exchanged among mobile phone users frequently contain “emoticons (smileys)” and “emoji (pictograms)”. Some consumers have started to use services that add a relevant animated image to a message. Consumers will start to exchange animated messages if they are available. This paper proposes ...
