Mirror Modeler: A Web Based Interactive Mathematics Modeling System

This paper presents an open user modeler called the mirror modeler that pretends to be the student and solves sample questions while the student watches mimicking student errors. This ability when added to an interactive teaching environment seems to greatly facilitate the learning process for two types of mathematical series while raising a serious question about the complexity of the third.

Modeling Object-Oriented Program Execution

This paperdescribes awayof organizing information about an object-orientedprogram’s execution. The context is our system for visualizing that execution. The critical constraints are completeness, compactness, and efficient retrieval. We describe our design and how it meets these constraints.

New skew equienergetic oriented graphs

Let $S(G^{sigma})$ be the skew-adjacency matrix of the oriented graph $G^{sigma}$, which is obtained from a simple undirected graph $G$ by assigning an orientation $sigma$ to each of its edges. The skew energy of an oriented graph $G^{sigma}$ is defined as the sum of absolute values of all eigenvalues of $S(G^{sigma})$. Two oriented graphs are said to be skew equienergetic iftheir skew energies...

Modeler Independent Procedural Interfaces for Solid Modeling

This paper describes modeler independent application programming interfaces called adaptors. A solid modeler is augmented with an adaptor so as to provide a standard procedural interface to applications and function as a geometric server. Adaptors give the applications portability and free the application programmers from the details of specific modelers. Adaptors have been developed at USC for...
