4.5 Ellipse (0 < e < 1)

An ellipse with eccentricity e (where 0 < e < 1) is the set of points P in the plane whose distances from a fixed point F are e times their distances from a fixed line d. We obtain such an ellipse in standard form if

  1. the focus F lies on the x-axis, and has coordinates (ae, 0), where a > 0;

  2. the directrix d is the line with equation x = a

Introduction

This is the fifth and final unit in the MSXR209 series on mathematical modelling. In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used.

This unit, the fifth in a series of five, builds on ideas developed and introduced in Modelling pollution in the Great Lakes

Patchworking as a Metaphor for Learning – Understanding youth, learning and technology
On basis of a close empirical examination of a Danish team of 'Power Users' and their work on a self-chosen learning challenge this thesis argues how we can theoretically understand, analyse and methodologically approach learning processes through the metaphorical lens of ‘patchworking’. The metaphor of patchworking highlights how learning processes can be seen as processes of stitching and weaving together different ‘patches and pieces’ into something new. The patches and pieces may not

A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process
