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…

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…

This study examined growth in graphical literacy for students contributing to an online, multimedia, communal environment as they advanced their understanding of biology, history and optics. Their science and history studies started early in Grade 3 and continued to the…

In 1993 Carey and Smith conjectured that the most promising way to boost students’ understanding of the nature of science is a “theory-building approach to teaching about inquiry.” The research reported here tested this conjecture by comparing results from two…

Over four academic years a design experiment was conducted involving four online university courses with the goal of shifting from Guided to Self-Organized Inquiry to foster Knowledge Building communities in the classroom. Quantitative analyses focused on notes contributed to collective…

Academic researchers have contributed in the knowledge of future studies, and this knowledge has been improved through real application in companies and public institutions. Business executives and public administrators permanently have to face difficult decision processes, and therefore have to…

In the present paper, specimens of Cerambycidae were examined in the Entomology Museum of Central Anatolia Forestry Research Directorship, Ankara, Turkey. As a result of identification of these specimens, thirty-eight species and two subspecies belonging to twenty-eight genera of five…
