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…

A key problem in model-based object recognition is selection, namely, the problem of determining which regions in the image are likely to come from a single object. In this paper we present an approach that extracts and uses color region…

The effect of schooling on nutritional knowledge, attitudes and nutritional outcomes in Ethiopia was investigated. Data were obtained in late 1989 in Debre Birhan in Shoa province from three groups: 267 mothers, 114 clinic users and six primary schools with…

Stemming from the dialectical concepts of critical epistemology developed by feminism and Critical Theory (specifically, the Frankfurt School), this thesis attempts to articulate the political dimension of knowledge and to demonstrate how this dimension is incorporated into the liberatory pedagogical…

This thesis is about how medical knowledge is constructed by staff for patients and their families in a Japanese 'comprehensive care' facility for the treatment of epilepsy (the JEC). The thesis sets out to explain the possible reasons for differences…

A survey was undertaken to assess the knowledge, attitudes and practices, with respect to malaria, of 300 women from six randomly selected rural communities in Central Ethiopia from December 1991 to February 1992. Eighty-five per cent were able to recognize…

Concept mapping in college-level physics was investigated. The study was carried out in three parts. First, an attempt was made to validate concept mapping as a method of evaluating student learning at the junior college level (ages 16-21). Several measures…

A methodology was developed in this study for identifying the cognitive, pedagogical, and computational characteristics of computer-based learning environments. The characterization of the cognitive and pedagogical features was achieved by decomposing the learning environments into episodes which were composed of…
