We present a simulator for militar fluvial boats, in which we concentrate in the task of shooting. Shooting from a boat is particularly challenging, due to rapid movements, river conditions, and special considerations that should be taken into account for a shooters security. We present a hardware platform that simulates boat movements under different(More)
In this paper we propose to analyze the variability of brain structures using principal component analysis (PCA). We rely on a data base of registered and segmented 3D MRI images of normal subjects. We propose to use as input of PCA sampled points on the surface of the considered objects, selected using uniformity criteria or based on mean and Gaussian(More)
Although image processing becomes increasingly important in most applications such as medicine, image processing and visualization is usually not a part of the medical education and therefore not widely spread in clinical daily routine. Contrary to students from computer science, medical students are usually not familiar to computational models or(More)
The Pequeños Científicos (Little Scientists) program is a K-6 initiative for the development of scientific and technological competencies of Colombian children. Over the past 5 years, Pequeños Científicos has developed and evaluated some teacher training, strategic planning and assessment tools for the institutionalization of the program in the educational(More)
We study the feasibility of using Belief, Desire and Intention agents for modeling the phenomena of urban growth and segregation. Uncertainty, typical of real world situations is modeled using possibility theory. We have also implemented a simple visualization tool whose aim is to track the changes in the model. Some preliminary experiments suggest that(More)
The urban planning process for fast growing cities like Asian and Latin American cities poses huge challenges. One of the most important challenge is the interaction of many stakeholders who have their own tasks, tools, and data. This paper presents a data conversion process and a data model for creating interactive visualizations that support the(More)
Decision making in the context of urban and regional planning requires communication among different stakeholders. This communication process has several barriers because of domain differences, the different nature and types of data, lack of integrated analysis tools, deficiencies in the interaction with data, and information overload. To overcome these(More)
