Geometry Students’ Arguments About a 1-Point Perspective Drawing

A differential geometry perspective about multiple data streams preprocessing

In the Multiple Data Streams (MDS) environment, data sources generate data with no end in sight. Because of the difference of data sources, transaction numbers of MDS are not always equal to each other during a same period. Preprocessing MDS to obtain same number of samples for each stream is an essential step for lots of mining tasks. All existing preprocessing methods assume that data arrive ...

Arguments About Values

Arguments are more or less persuasive depending on the values their outcomes promote and demote. This idea, closely related to Perelman’s ideas work on argumentation, has been formally modeled by Bench-Capon in his well-known Value-Based Argumentation Frameworks, based on Dung’s abstract argumentation. In this paper, the question is addressed how arguments about which values are promoted and de...

Formalising arguments about norms

In most attempts to model legal systems as formal argumentation systems, legal norms are viewed as an argumentation’s system inference rules. Since in formal argumentation systems inference rules are generally assumed to be fixed and independent from the inferences they enable, this approach fails to capture the dialectical connection between norms and arguments, where on the one hand legal arg...

Fixed-Point Ellipse Drawing Algorithm

This algorithm draws ellipses with integer centres and decimal radii on discrete devices using fixed-point arithmetic. These ellipses have both X and Y axis parallel to the coordinate axes. It uses forward differences to diminish its cost. It has a low comp utational complexity while the error is lower than traditional algorithms. This algorithm works in the squared R space (fixed-point) and tr...
