This paper addresses the problem of recovering relative structure, in the form of an invariant, referred to as projective structure, from two views of a 3D scene. The invariant structure is computed without any prior knowledge of camera geometry, or…

The design of the control laws governing the behavior of individual agents is crucial for the successful development of cooperative agent teams. These control laws may utilize a combination of local and/or global knowledge to achieve the resulting group behavior.…

In this note we discuss how recognition can be achieved from a single 2D model view exploiting prior knowledge of an object's structure (e.g. symmetry). We prove that for any bilaterally symmetric 3D object one non- accidental 2D model view…

It is obvious to anyone familiar with the rules of the game of chess that a king on an empty board can reach every square. It is true, but not obvious, that a knight can reach every square. Why is…

The guava (Psidium guajava 1.) cv. Paluma has been cultivated in Sao Francisco Valley, Northeastern of Brazil, for in natura consumption and processing purposes. In spite of its importance, there are few scientific knowledge regarding guava physiology, nutrition, irrigation and…

Considering the importance of the debate on the topic of disasters related to landslides, flooding and technological risks, under international and more recently in Brazil, this work analyzes the situations of vulnerability risk areas on the Northern Coast of São…

In a pervasive media and technology landscape that is increasingly global, participatory and connected, one in which learners and teachers can increasingly become creators of knowledge rather than mere consumers of prepared messages and ideas, it is vital for the…

Presented at the 21st Conference of the Comparative Education Society in Europe (CESE), held in Granada, in Summer 2006., One of twenty-five papers exploring our contemporary reading of what is global, the way we comparatively understand this world of new…

Nos preocupamos mucho de la enseñanza de la bioética y de las mejores metodologías para conseguir trasmitir conocimientos, actitudes y valores, pero no hemos reflexionado suficientemente en la importancia de los valores éticos en la educación para la salud, y…

Human and social studies on emotions are diversely interested in the reality emotions signify. Within this field, the discourse analysis approach focuses its attention on the linguistic expression of emotions and cannot thus extend its evaluation on psychological or sociological…
