The paper analyzes the methods of processing measurement data of the seismic observation method used in the International Seismic Monitoring System and the Main Center for Special Control of the State Space Agency of Ukraine to solve problems of monitoring nuclear tests at foreign test sites. The directions of improvement of known and development of new methods of processing of measuring data of seismic method of detection in the conditions of presence and absence of a priori information on the form of a seismic signal are defined. If the form of the expected seismic signal is known, then the monitoring of foreign test sites by the seismic grouping system can be realized by supplementing the method of controlled directional reception with a correlation scheme of measurement data processing. In the absence of information on the shape of the seismic signal, the monitoring of the test site is carried out by dividing the group into two subgroups, followed by the cross-correlation method between the original samples of each subgroup. For a network of three-component stations, if there is information about the shape of the expected seismic signal, the method of comparison with the reference signal is used. In the absence of reference signals, monitoring is implemented using system discriminant, which takes into account the kinetic and dynamic properties of the expected signal with a cell from a given area. Possibilities of application of seismic stations of the International system of seismic monitoring are analyzed, use of measuring data which for the decision of problems of monitoring of foreign landfills allows to reduce time of definition of parameters of a seismic event essentially. A feature of the signals registered by seismic stations of the International System is the presence of types of seismic waves characteristic of events with cells in the near zone. Implementation of monitoring of test sites is possible by taking into account the polarization and dynamic properties of seismic waves. The implementation of the proposed approaches will increase the efficiency of solving the problem of detecting nuclear explosions at foreign test sites.

The paper gives a report on the Karolinska Hospital Information System in three parts.In part I, the information problems in health care delivery are discussed and the approach to systems design at the Karolinska Hospital is reported, contrasted, with the traditional approach.In part II, the data base and the data processing system, named T1—J 5, are described.In part III, the applications of the data base and the data processing system are illustrated by a broad description of the contents and rise of the patient data base at the Karolinska Hospital.
