The teaching process can be represented as a sequence of lessons beginning at the specific moments of time that are generally not equidistant. The sequence of teaching effects which will transfer the pupil into a preassigned final state in a definite sense has to be optimal. The algorithm which carries out the transfer process at the earliest possible time is considered to be the best.","PeriodicalId":391891,"journal":{"name":"Proceedings of the 9th International Scientific and Practical Conference of Students, Post-graduates Modern Techniques and Technologies, 2003.

While it is difficult to obtain an acceptable combination, a compromise between these parameters is recommended. By optimizing the two-level presentations, the minimal (short) function can be determined. The problem of the Boolean function minimization is the determination of the function minimal by the number of literals (minimal function) or by the number of conjunctions (short one). In optimizing multi-level presentations the methods of decomposition and factorization are used. Conjunctions factorization is the method of algebraic change of the conjunctions factors of one Boolean variable: factors including not less than two literals are extracted.","PeriodicalId":391891,"journal":{"name":"Proceedings of the 9th International Scientific and Practical Conference of Students, Post-graduates Modern Techniques and Technologies, 2003.

The results of EM have shown, that heat treatment lead to destruction of needle-like structure of tremolite crystals. The dates of DTA also testified as changes in tremolite composite.

This paper considers the structure, mechanical characteristics and the peculiarities of plastic flow of SMC Armco-iron subjected to thermal annealing at different temperatures. Structural investigations were performed by the methods of translucent electron microscopy (TEM). Investigation of straining relief showed that regardless of the mode and the quantity of passages in even-channel angular pressing the samples of SMC alpha-Fe have high tendency to the straining localization. Mechanical properties of the investigated samples are determined by the mode of ECAP. Thermal annealing of the samples of SMC alpha-Fe allows one to change their mechanical characteristics within wide ranges.","PeriodicalId":391891,"journal":{"name":"Proceedings of the 9th International Scientific and Practical Conference of Students, Post-graduates Modern Techniques and Technologies, 2003.

For the anesthesiologist, it gives possibility to appreciate the various pathologies and possibility to take action for accident prevention.
