During the IBIS project a high-quality data library of continuous and intermittent physiological signals and variables from patients during intensive care and surgery has been collected. To facilitate exploration of the full content of this data library a data browser was developed, which offers a flexible graphical display of the collection of multivariate data. To supplement the functionality of the display of the 'raw' data, a set of screening and pre-processing tools has been developed. A separate trend analysis tool offers a convenient overview of an entire recording focusing on the slow changes in the general state of the patient and the interaction between different physiological subsystems seen from a long-term perspective. A frequency analysis tool for processing the electroencephalography (EEG) signals has been integrated in the data browser to facilitate a quick screening of the cerebral function. The data library is the foundation of the development and validation of biosignal interpretation methods. This process can potentially be more productive using the described tool for algorithm prototyping based on a graphical network specifying the interaction between data processing primitives.

An automatic programming system using object-oriented programming techniques is described. This system is intended for use as a design tool for signal processing software. The system starts with a graphical description of an algorithm, supports interactive editing and performance analysis, and produces as output source code which implements the algorithm.

ESA's Earth Observation (EO) missions provide a unique dataset of observational data of our environment. Calibration, algorithm development and validation of the derived products are indispensable tasks for an efficient exploitation of EO data and form the basis for reliable scientific conclusions. In spite of its importance, the cal/val and algorithm development work is often hindered by insufficient means to access data, time consuming work used to identify suitable in-situ data matching the EO data, incompatible software and limited possibilities for a rapid prototyping and testing of ideas. In view of the amount of data produced by the future ESAs series of Sentinel satellites, a very efficient technological backbone is required to maintain the ability of ensuring data quality and algorithm performance. Brockmann Consult has developed such a backbone based on leading edge technologies within an ESA R&D study. Calvalus is a new processing system that utilises the map-reduce programming model with a distributed file system.
