ic current, etc.), but with other characteristics (10g в†’ 100g, 5mA в†’ 0.5mA, 1Hz в†’ 10Hz, 5 impulses в†’ 15 impulses, etc.). Amplifiers, code converters, logic components of electronics are the examples of elements with logic hetero-reactivity. Neurons do not possess physical hetero-reactivity as they can perceive only potentials of action and generate the potentials. But they have logic hetero-reactivity and they can transform frequency and pulse count. They do not transform a physical parameter as such, but its characteristics. Any system consists of executive and operating elements. At the same time any control block of any system itself consists of some kind of parts (elements), so it also falls under the definition of systems. In other words, control block and its parts are specific systems (subsystems) themselves with their goals, and they have their own executive elements and local control blocks operating these executive elements. Compulsory condition for part of them is their ability to hetero-reactivity of one or other sort. The effect of their control action consists only in their relative positioning. Command is entered into the local control block (condition of the task, the goal/objective) and the latter continually watches that the result of action always satisfies the command. At that, the command can be set from the outside by other system external in relation to the given one, or the self-training block may "decide" independently to change the parameters (but not the goal) set by the command. So, the elements of control may be the same as the executive elements. The difference is only in relative positioning. Director of an enterprise is just the same kind of individual as any ordinary engineer. All elements of the system, both executive and controlling, are structured according to a certain scheme specific for each concrete case (for each specific goal), but all of them must have the "exit" point/outlet /, whence the result of action of the given element is produced, and two "entry points" - for external influence and for entry of the command. If the exit points of any elements are connected to the entry points for external influences of other elements, such elements are executive. In this case executive elements are converters of one kind of results of action into the other, because the results of actions of donor systems represent external influence for the recipient systems (executive elements). They (external influences) ostensibly enter the system and exit it being already transformed into the form of new results of action. If exit points of elements are connected to command entry points of other elements, such elements are controlling and represent a part of control block. In such cases the result of action of some systems represents the command for the executive elements, the instruction on how to transform the results of action of donor systems into the results of action of recipient systems. But...
