RESUMO
The experimental data presented in this paper address the energy loss determination for argon at 4 MeV/u projectile energy in laser-generated carbon plasma covering a huge parameter range in density and temperature. Furthermore, a consistent theoretical description of the projectile charge state evolution via a Monte Carlo code is combined with an improved version of the CasP code that allows us to calculate the contributions to the stopping power of bound and free electrons for each projectile charge state. This approach gets rid of any effective charge description of the stopping power. Comparison of experimental data and theoretical results allows us to judge the influence of different plasma parameters.
RESUMO
The paper shows that the currently available Russian and foreign computer medical monitors (CMMs) may generally solve the simplest tasks of data visualization, recording, and archiving. It is justified that to enhance the "intellectuality" of CMMs, it is necessary to turn to the solution of the problems and tasks of medical monitoring, by using the whole range of methods for biosignal detection and processing, which has been accumulated in modern radio engineering, in the theory of communication, and in engineering and medical cybernetics.

Medical monitoring is regarded as a task of detecting and classifying human abnormalities. A computer medical monitor (CMM) is a complex hierarchical system with artificial intellect elements at the top levels of hierarchy. Each level of hierarchy performs a definite task in collecting and processing current information. Based on this approach, the authors put forward tasks of medical diagnostic and prognostic studies by developing the hierarchical network architecture of CMM.

Analysis of about 30 medical computer monitors has allowed the authors to make a conclusion on the present status of this field of medical engineering, operating properties and technical data. The parameters to be monitored, methods of their determination and processing are dealt with. The lines of further development of Russian medical computer monitors are outlined.

The paper deals with the problems of medical monitoring, namely how to solve those in the detection and classification of human abnormalities. The medical monitor is a complex hierarchic system and the authors state problems and tasks for each level of hierarchy and the objectives of studies in medical diagnosis and prediction while designing the hierarchic network structure of a medical computer monitor. A parallel is drawn between the image recognition theory and medical diagnosis.
