Modern Computer Algebra by von zur Gathen http://www.amazon.com/Modern-Computer-Algebra-Joachim-Gathen/dp/0521641764

Topology for Computing by Zomorodian http://www.amazon.com/Computing-Cambridge-Monographs-Computational-Mathematics/dp/0521836662/ref=sr_1_2?ie=UTF8&s=books&qid=1259939528&sr=1-2

Geometric Fundamentals of Robotics by Selig applies algebraic and differential geometry to problems in robotics.

Computational Homology by Kaczynski et al has applications of homology to image processing and nonlinear dynamics.

Robert Ghrist, http://www.math.uiuc.edu/~ghrist/, applies topology to problems in engineering, including robotics and sensor networks.

This book by Erica Flapan relating chemistry and algebraic topology was of use to my wife when she has writing her undergrad thesis. It seems like it might qualify.
