In order to substantially contribute to the NATO Feasibility Study on Active Layered Theatre Ballistic Missile Defence
(TBMD) the BMC4I and Interoperability aspects have been explored. The results of this exploration are captured in an
information architecture. This information architecture can be used as a reference and assessment framework in the national
evaluation of the results of the above-mentioned feasibility study.

This paper addresses the problem that in many cases, observations cannot provide complete fields of the measured
quantities, because they yield data only along a single cross-section through the examined fields. The paper describes a new
Fourier-adjustment technique that allows existing fractal models to build realistic surroundings to the measured cross-sections.
This new approach allows more representative calculations of cloud radiative processes and may be used in other areas as well.

An adaptive autoregressive moving average (ARMA) modelling of nonstationary EEG (Electroencephalography) by
means of Kalman smoother is presented. The main advantage of the Kalman smoother approach compared to other adaptive
algorithms such as LMS or RLS is that the tracking lag can be avoided. This advantage is clearly presented with simulations.
Kalman smoother is also applied to tracking of alpha band characteristics of real EEG during an eyes open/closed test. The
observed tracking ability of Kalman smoother, compared to other methods considered, seemed to be better.

This viewgraph presentation provides information on optimizing the travel distance between two points on a curved
surface. The presentation addresses the single source shortest path problem, fast algorithms for estimating the eikonal
equation, fast schemes and barrier theorems, and the discontinuous Galerkin method, including hyperbolic causality, finite
