This book provides the first comprehensive overview of theoretical issues, historical developments and current trends in ICALL (Intelligent Computer-Assisted Language Learning). It assumes a basic familiarity with Second Language Acquisition (SLA) theory and teaching, CALL and linguistics. It is of interest to upper undergraduate and/or graduate students who study CALL, SLA, language pedagogy, applied linguistics, computational linguistics or artificial intelligence as well as researchers with a background in any of these fields.

Singularity theory is an area of mathematics at the crossroads of algebraic geometry, topology, and differential equations.
Initiated by Thom, Arnol'd and others in the 1970s, it quickly developed into a central area of mathematics.
Challenging problems on singularities were both a driving force and a beneficiary of the development of Grobner basis methods in computer algebra.
This unique volume is a collection of recent original research by some of the leading figures of singularity theory of the last three decades. The articles highlight a large variety of techniques, ranging from...
