TL;DR: A new multimodal biometric database, acquired in the framework of the BiosecurID project, is presented together with the description of the acquisition setup and protocol and features such as: realistic acquisition scenario, balanced gender and population distributions, availability of information about particular demographic groups, and compatibility with other existing databases.

TL;DR: The objective of BSEC'2009 was to evaluate different online signature algorithms on two tasks: the first one aims at studying the influence of acquisition conditions (digitizing tablet or PDA) on systems' performance; the second one aims on studying the impact of information content in signatures on systems’ performance.

TL;DR: A new DTW-based on-line signature verification system is presented and evaluated and its performance is among the best systems reported in the state of the art.

TL;DR: A minimal-pair-based CAPT tool that implements exposure–perception–production cycles and provides automatic feedback to learners is tested for effectiveness in training adult native Spanish users (English level B1–B2) in the production of a set of difficult English sounds.

TL;DR: A new algorithmic technique is presented which allows automatic transformation of the task graph of any unstructured application to a series-parallel form (nested-Parallelism) and shows that a wide range of irregular applications can be expressed using a structured coordination model with a small loss of parallelism.
