	abstract = {Morse theory studies the relationship between the topology of a manifold M and the critical points of a scalar function f defined over M. Morse and Morse-Smale complexes, defined by critical points and integral lines of f, induce a subdivision of M into regions of uniform gradient flow, representing the morphology of M in a compact way. Function f can be simplified by canceling its critical points in pairs, thus simplifying the morphological representation of M, given by Morse and Morse-Smale complexes of f. Here, we propose a compact representation for the two Morse complexes in 3D, which is based on encoding the incidence relations of their cells, and on exploiting the duality among the complexes. We define cancellation operations, and their inverse expansion operations, on the Morse complexes and on their dual representation. We propose a multi-scale representation of the Morse complexes which provides a description of such complexes, and thus of the morphology of a 3D scalar field, at different levels of abstraction. This representation allows us also to perform selective refinement operations to extract description of the complexes which varies in different parts of the domain, thus improving efficiency on large data sets, and eliminating the noise in the data through topology simplification.},

	abstract = {The precessional switching process of a uniformly magnetized thin film with in-plane anisotropy subject to pulsed magnetic fields applied in the film plane is analyzed. Critical fields required to achieve switching are studied for the case when the applied field is constant during the pulse duration and forms arbitrary angles with the hard axis. By using two integrals of magnetization motion, the explicit expressions for the critical field are derived. The formulas for durations of rectangular magnetic field pulses that guarantee the precessional switching of magnetization are presented as well.},

	abstract = {The National Aeronautics and Space Administration (NASA) Space Shuttle program is a multi-billion dollar activity scheduled to span over 40 years. Maintaining such software with requirements for high reliability and mission safety taxes current development methods. The authors present how independent verification and validation (IV amp;V) activities are used to support these requirements. They also show how the IV amp;V activities for this program differ from those of more traditional software developments},
