molecular understanding of three-dimensional (3d) peptide: mhc models require both basic knowledge of computational modeling and skilled visual perception, which are not possessed by all students. the present model aims to simulate mhc molecular structure with the hands and make a profound impression on the students.

This work introduces a procedure for automatic 3D modeling and discusses its performance in the context of a medical application, namely the 3D modeling of palate’s casts. The general interest of the proposed method lays in the fact that a widespread use of 3D modeling in non-engineering applications requires automatic procedures. The specific interest is in the intriguing mixture of open issue...

To support 3D architectural modeling, geometric constraints are introduced. Explicit and implicit geometric relations between building elements can be expressed by the designer and imposed on the 3D geometry of the design. A complete set of constraint types is defined. Constraints are satisfied through Numerical Methods to achieve that the model responds to the designers’ actions in a user-intu...

This paper models competing mechanism games as extensive games where the extensive form is incompletely understood by a modeler, typically because the modeler doesn’t see all the messages that are being exchanged and doesn’t understand all the contracts that can be enforced. For this reason, the revelation principle can’t be used to characterize supportable outcomes. The paper provides a relati...

It is common knowledge that attention is important for learning. We need to utilize attention in order to learn something efficiently and effectively. Similarly, we may also need to acquire familiarity with (i.e., learn) our surroundings in order to utilize our attention. In this study, learning is defined as a product of one’s exposure to natural visual stimuli. Using a virtual model of a natu...

This paper presents a novel representation for three-dimensional objects in terms of affine-invariant image patches and their spatial relationships. Multi-view constraints associated with groups of patches are combined with a normalized representation of their appearance to guide matching and reconstruction, allowing the acquisition of true three-dimensional affine and Euclidean models from mul...

What are the key features of creative teachers’ pedagogical practice and just how do teachers teach creatively and teach for creativity, thus fostering children’s creative learning? This chapter seeks to respond to these questions putting forward a three-dimensional model in which creative practice is seen as a product of the dynamic interplay between the teacher’s personal qualities, the pedag...

Given an in nite sequence t= ( k)k of −1 and +1, we consider the oriented walk de ned by Sn(t) = ∑n k=1 1 2 : : : k . The set of t’s whose behaviors satisfy Sn(t) ∼ bn is considered (b ∈ R and 0¡ 61 being xed) and its Hausdor dimension is calculated. A two-dimensional model is also studied. A three-dimensional model is described, but the problem remains open. c © 2000 Elsevier Science B.V. All ...

In this survey report we present a study of how features can be used to solve the problems in handling 3D geometric models. We outline the basic aspects of feature based processing of models and discuss some representative application areas. The report also lists the current areas of research in this subject.

Object-oriented conceptual models strive to capture more semantics in order to better represent requirements of real-world applications. Aggregation is a powerful construct for semantic modeling. Intuitively, it relates a composite object to its component objects. This paper presents a new version of aggregation, with a generalized version of cardinality constraints and a new subcategorization ...
